Migraine – Condition Resources

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

Over 80 NHS publications since 2005 have recommended acupuncture both for tension headaches and migraine (and many more worldwide (Birch et al, 2018)

About the research: It is worth noting that in research, randomised controlled studies (RCT) are the most reliable in terms of quality of evidence, with a systematic review or meta analysis of numerous studies being the best way of seeing the overall picture of the state of the evidence. Below we have a selection of the available research, which does include some larger RCTs, and reviews of the literature alongside smaller studies. The n= figure tells you how many people were participants in the study.

The British Acupuncture Council (BAcC) reviewed the evidence for acupuncture in migraine and tension headaches, where a large number of trials have been carried out, considerably more effective than placebo (Tavola et al, 1992.) The BAcC concluded there was some evidence that acupuncture has a significant therapeutic effect on symptoms such as pain and frequency in migraine attacks. It was also noted in a crossover research trial that in addition to demonstrating a significant effect in reduction of frequency of attacks and their duration, that acupuncture has a very low side effect profile (Hesse et al, 1994; Loh et al, 1984).

The British Acupuncture Council has a Research digest where they examined some recent studies on headache and migraine, as well as an evidence based factsheet (links are below).

In a randomized clinical trial (N=66; Yang et al, 2011) comparing acupuncture to the maintenance drug topiramate for chronic migraine prophylaxis (prevention), acupuncture resulted in a statistically significant, greater reduction in the number of monthly days with moderate to severe migraines (than did topiramate), and had fewer side effects than the drug. The study concluded that acupuncture is an effective and well-tolerated alternative to topiramate for migraine prevention.  The researchers said: “We suggest that acupuncture could be considered a treatment option for CM patients willing to undergo this prophylactic treatment, even for those patients with medication overuse.”  (Yang et al, 2011).

Acupuncture has had a good profile for both migraine and tension headaches since the Cochrane review of 2009, which was updated in 2016 (Linde et al), including 22 trials (n=4985), finding evidence to suggest that adding acupuncture to symptomatic treatment of attacks reduces the frequency of headaches.  The researchers expressed the need for further long term trials in this area.

The current NICE headache guidelines (2012; 1.3.9) state the following: “Prophylactic treatment: Consider a course of up to 10 sessions of acupuncture over 5 to 8 weeks for the prophylactic treatment of chronic tension‑type headache.”

The German Migraine and Headache Society and the German Society of Neurology recommend acupuncture for prevention of migraine in patients who refuse or do not tolerate prevention with drugs. They also state that: “there is some evidence that traditional Chinese acupuncture is effective in the treatment of acute migraine attacks” (Dierner et al, 2019; p12).

A systematic review on migraine without aura (Xu et al, 2018) examined 14 RCTs (n=1155), drawing the conclusion that acupuncture is safe, more beneficial that sham control in addressing symptoms, although they were reserved in the strength of this finding by the quality of some of the evidence available, meaning further studies were warranted.

Ambrosie et el, (2012) looked at cost effectiveness of acupuncture use in this field, using the NHS measure of cost per quality adjusted life year (QALY) gain from treatment usage, finding acupuncture to be cost effective by this measure.

Melchart et al (2003), compared acupuncture with the use of the drug sumatriptan (6 mg subcutaneously), and placebo injection, in an RCT (n=179), in early treatment of an acute migraine attack.  Their main outcome measure was the number of patients in whom a full migraine attack was prevented, with both acupuncture and sumatriptan being more effective than a placebo injection in the early treatment of an acute migraine attack. When an attack could not be prevented, sumatriptan was more effective than acupuncture at relieving headache, but had less side effects than did the drug.  They acknowledged that the practicality of providing acupuncture in an outpatient setting at the onset was more difficult than the use of drugs, but highlighted its positive role in the prevention (prophylaxis) of attacks.

A systematic review protocol was put forward recently (Zhang et al, 2020) for auricular (ear protocol) acupuncture in migraine, so it will be of interest to see the outcome when this is published.

Mechanisms of action:

Acupuncture studies have shown it can: provide pain relief by stimulating nerves in body tissues and leading to endorphin release (natural painkilling substances), as well as downregulating the brain and nervous system’s reaction to stress and pain (Zhao 2008; Zijlstra et al, 2003; Pomeranz, 1987).

Acupuncture stimulates the body to create its own natural painkilling substances, such as Beta Endorphins (β-Endorphin). In studies acupuncture has been shown to stimulate the production of natural painkillers called opioid-like peptides (OLPs), including β-Endorphin: For example, this was shown in an RCT in 90 patients with a range of painful disorders (Petti et al, 1998). The same study showed acupuncture also and enhanced the activity of immune cells (lymphocytes, natural killer cells and monocytes) that help fight infections and diseases (Petti et al, 1998).

Zijlstra et al (2003) reviewed the effects and mechanisms of acupuncture in treating various inflammatory diseases and conditions. They proposed the mechanisms of action:

  • Acupuncture may release neuropeptides from nerve endings that have vasodilative and anti-inflammatory effects through CGRP.
  • Acupuncture may also interact with substance P, which is involved in pain transmission and inflammation.
  • Acupuncture may contribute to analgesia by stimulating the release of β-endorphin, which binds to opioid receptors and inhibits pain signals.
  • Acupuncture may influence the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines such as TNF-α and IL-10.

Acupuncture can activate mast cells at acupoints, which release histamine, serotonin, adenosine, and other mediators that modulate nerve transmission and inflammation (Li et al, 2022)

Acupuncture has been shown in animal models to promote the release of factors that involved in the reduction of inflammation (vascular and immunomodulatory factors – (Kim et al, 2008; Kavoussi and Ross, 2007 [review article]; Zijlstra et al, 2003), and also to affect levels of serotonin (in an animal model), and other peptides in the brain and nervous system and modulate blood flow in the brain and elsewhere in the body, in humans (Zhong and Li, 2007; Shi et al, 2010; Park, 2009).

Electroacupuncture (EA) has been shown in a rat model (Li et al, 2008) to have anti-inflammatory benefits by modulating the hypothalamic-pituitary-adrenal (HPA) axis, (HPA axis regulates the stress response and immune function).  Specifically, Li et al outlined that EA sets off a cascade in the brain (via corticotropin-releasing hormone, and adrenocorticotropic hormone) to produce cortisol, which reduces inflammation and oedema.

Chronic Pain in General

“Acupuncture is effective for the treatment of chronic musculoskeletal, headache, and osteoarthritis pain. Treatment effects of acupuncture persist over time and cannot be explained solely in terms of placebo effects. Referral for a course of acupuncture treatment is a reasonable option for a patient with chronic pain”. (Vickers et al, 2018: large chronic pain review of high quality RCTs updating a previous meta-analysis; 39 trials, n=20827; conditions addressed chronic headache, back/neck pain and osteoarthritis)

Another recent overview (Yin et al, 2017) confirms that there is increasing evidence for acupuncture  as an effective, safe, and cost-effective intervention in chronic low back, neck, shoulder, and knee pain, as well as headaches.

The NHS body in charge of which treatments should be used in particular conditions recommends acupuncture for chronic pain:  The NICE Scenario Management guidelines (2021) for chronic pain state: “consider a course of acupuncture or dry needling, within a traditional Chinese or Western acupuncture system”

Overall, a large systematic review has found acupuncture a cost effective intervention for several painful conditions (Ambrósio et al, 2012).

Knee pain

Knee pain was included in large chronic pain review of RCTs updating a previous meta-analysis (Vickers et al, 2018; 39 trials, n=20827) acupuncture showed a significant clinical superiority over usual care and a smaller advantage over sham.

A systematic review and meta-analysis of 17 trials, showed significant benefits whereby in patients in study groups having received acupuncture, this was associated with significantly reduced chronic knee pain 12 weeks (Zhang et al, 2017).  Specifically comparing treatments including acupuncture in osteoarthritic knee pain, Corbett et al’s (2013, n=9709) systematic review and network meta-analysis found that acupuncture could be considered as one of the more effective physical treatments for alleviating osteoarthritis knee pain in the short-term: Acupuncture was ranked second out of 21 physical treatments in this study.  The team also clarified that further research is also warranted in this area, due to the quality of the research available in some treatment areas across the studies.

Osteoarthritis:

Osteoarthritis of the knee is a chronic degenerative disease, with symptoms of pain, stiffness, swelling and dysfunction.  OA of the knee is the most prevalent pain- and disability inducing condition in adults over 50 years old (Araya-Quintanilla et al. 2022).

An overview of 15 systematic reviews of pain relief in patients with osteoarthritis knee by Araya-Quintanilla et al. (2022) found that in the short term, acupuncture had a moderate positive impact on both pain intensity; and knee function, compared to the control groups. The evidence was rated as low to very low quality according to GRADE ratings.

The systematic review of eleven RCTs with meta-analysis by Tian et al. (2021) found that acupuncture had a positive effect on reducing pain and improving functional activities in patients with knee osteoarthritis. However, there was no significant effect on relieving stiffness or improving the quality of life (mental or physical health) compared to sham acupuncture. The findings suggest that acupuncture can be recommended as a beneficial alternative therapy for patients with chronic pain and knee OA, but further studies are needed to verify the effectiveness in function improvement. The results were confirmed by cumulative Z-curve analysis.

Liu, J., et al, 2022; In this multicentre RCT (n=625), patients were randomly assigned (1:1:1) to receive acupuncture at acupoints with Lower Pain Threshold (LPT); acupuncture at acupoints with Higher Pain Threshold (HPT); and no acupuncture (waiting-list group).  Measures of pain and symptoms (WOMAC) from baseline to 16 weeks; outcome measures of daily life impact of condition (SF-12 score); and active knee range of motion (ROM) were used as comparators. From baseline to 16 weeks, the effects of acupuncture at acupoints with lower versus higher PT were similar, as both were effective for patients with OA of the knee, “results confirmed the positive effects of acupuncture on pain, stiffness, physical function and quality of life of in patients” compared to the waiting list group. 

A further systematic review and meta-analysis is due as per the recent protocol in the BMJ (Lui, C.Y., et al; 2022).

Mechanisms of Action

Acupuncture stimulates the body to create its own natural painkilling substances, such as Beta Endorphins (β-Endorphin). In studies acupuncture has been shown to stimulate the production of natural painkillers called opioid-like peptides (OLPs), including β-Endorphin: For example, this was shown in an RCT in 90 patients with a range of painful disorders (Petti et al, 1998). The same study showed acupuncture also and enhanced the activity of immune cells (lymphocytes, natural killer cells and monocytes) that help fight infections and diseases (Petti et al, 1998).

Irritable Bowel Syndrome (IBS) – Condition Resources

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

Research and Resources on Irritable Bowel Syndrome and Acupuncture:

A scholarly search of the available research papers on the terms “acupuncture” + “IBS” yields over 6640 papers, and narrowing this to “RCT” to identify Randomised Controlled Trials, gives over 900 results; of which 40% have been carried out since 2017 (Google Scholar). This suggests that acupuncture is being used traditionally and currently in this area, leading to a body of research being carried out, the pace of which has increased in recent years, indicating increased recognition that it is worthy of scientific appraisal regarding its potential role.

For constipation, see also our dedicated page here

Interpreting the research:

When reading health research, it is important to know that Systematic Reviews or Meta Analyses of a large number of high-quality research studies are the very best way to be able to say to what extent a given treatment can address a condition, symptom, or set of symptoms.  The next best level of evidence is the individual Randomised Controlled Study (RCT) which uses a systematic technique to compare two or more groups of patients receiving different treatments (or a treatment against a “control”, or no treatment).  In acupuncture trials, the nature of the control group is of particular interest as it is hard to blind a patient to whether they are having a needle inserted or not, and even more challenging to blind the researcher/team to this.

The means and quality of how research is carried out varies considerably from country to country, and in terms of how an intervention is compared to another intervention (or a control).  Of note is the fact that “sham” acupuncture (where needles are placed in apparently inert locations rather than traditional acupuncture points) is not really an inert process as it has physiological effects, so that comparing sham and “true acupuncture” may therefore not give a clear picture alone; but and form a part of a research body where acupuncture versus no treatment, vs conventional treatment or vs a different approach/modality also form part of the evidence base.

The n= figure (where quoted in research) tells you how many people were participants in the study, and usually the larger a study (when it is of good quality and design), the more likely it is to be reliable and applicable to larger populations. When (statistical) “significance” is discussed in view of studies it has a very particular meaning – it is the confidence in the data (using statistical tests) that tells us how likely a result could have just come about by chance. The lower the possibility of a chance result, the more likely it is due to the intervention in the experiment. When you are reading a trial/study, the “p” is the number telling us of significance, and this must be under 5% (or p less than 0.05) to mean we can say it is a (statistically) “significant” result.

The Research:

The British Acupuncture Council has a Research digest where they examined some recent studies on IBS, such as MacPherson et al (2017; n=116) in a follow up two years after their RCT acupuncture for IBS, finding a favourable result 24 months on.  Another RCT for diarrhoea type IBS (Zheng et al, 2016; n=448) found the acupuncture group found a level of improvement in line with that of the group assigned pharmacological (Loperamide) intervention in terms of reducing stool frequency.

Zhu et al (2018a) conducted a network meta-analysis of diarrhoea type IBS, with 29 studies (n=9369) entailed in it, finding that acupuncture may improve symptoms, but that further high quality research was needed to corroborate the overall results.  A meta analysis of diarrhoea predominant IBS (Deng et al, 2017) looked at 17 trials (n=1333), finding improvement in clinical symptoms in the acupuncture groups. Similar trends have been seen in the trials for acupuncture in constipation predominant IBS, in a network meta-analysis, in which the quality of the trials was predominantly of high quality (40 trials n=11032; Zhu et al, 2018b). 

Qi et al (2022; n=90; pilot, multicentre RCT) examined a potential biological mechanism of action on IBS by reducing “visceral hypersensitivity” and modulating the gut-brain axis. They compared 3 groups: Specific acupuncture (real points); non-specific points; and sham acupuncture, and compared measurements of abdominal pain scores and types of stool. Both the specific and non-specific groups showed meaningful improvement in the IBS-D symptoms from baseline. It’s of note that non-specific real points do nonetheless have an impact, although the verum acupuncture effect is longer lived.

Research is ongoing, and recently, a protocol for a systematic review for anxiety and depression in IBS is awaited with interest (Li et al, 2021a), as is a systematic review of a comparison of acupuncture and pinaverium bromide in IBS (Li et al, 2021b), and a systematic review of acupuncture for adults with IBS-D (Guo et al, 2020). Search terms “acupuncture” + “IBS” + “RCT” + “protocol” since 2021 yield over 80 results, showing there is more to come in this area of growing interest in the very near future.

Mechanisms of Action

Acupuncture stimulates the body to create its own natural painkilling substances, such as Beta Endorphins (β-Endorphin). In studies acupuncture has been shown to stimulate the production of natural painkillers called opioid-like peptides (OLPs), including β-Endorphin: For example, this was shown in an RCT in 90 patients with a range of painful disorders (Petti et al, 1998). The same study showed acupuncture also and enhanced the activity of immune cells (lymphocytes, natural killer cells and monocytes) that help fight infections and diseases (Petti et al, 1998).

Moxibustion (an adjunctive acupuncture technique that involves burning herbs near the skin to stimulate acupuncture points) was found to reduce the expression of pro-inflammatory biomarkers (namely, TLR2, IRAK1, IKK-β and NF-κB) in an ulcerative colitis rat model; and to increase the expression of anti-inflammatory biomarkers (specifically, IFN- β and IL-10) in the rats’ colonic mucosa (Wang et al, 2015). Therefore it may have a protective and anti-inflammatory effect on the gut tissue.

Regarding Your Individual Condition and Symptoms:

Whilst the scientific studies are of great interest to researchers and acupuncturists in terms of comparing protocols, for the patient not versed in research they are less accessible, which is why when we asked “can acupuncture work for my (condition or symptom) we are not able to give a simple yes or no response.  We are able to tell you what experience we have had in our decades of experience in practise, of the types of outcomes we have seen in similar cases, and give you an idea of our level of experience and knowledge in that area, and how this could relate to your own individual situation.  For this, we recommend booking a free telephone consultation where we can answer any questions you have and give a realistic appraisal of what acupuncture may be able to provide.

Heartburn, Indigestion Condition Resources

Also known by its medical name of Dyspepsia, or commonly as indigestion or heartburn.

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

Research and Resources on Dyspepsia and Acupuncture:

A scholarly search of the available research papers on the terms “acupuncture” + “dyspepsia” yields over 8,600 papers, and narrowing this to “RCT” to identify Randomised Controlled Trials, gives over 970 results; of which 42% have been carried out since 2017 (Google Scholar). This suggests that acupuncture is being used traditionally and currently in this area, leading to a body of research being carried out, the pace of which has increased in recent years, indicating increased recognition that it is worthy of scientific appraisal regarding its potential role.

Interpreting the research:

When reading health research, it is important to know that Systematic Reviews or Meta Analyses of a large number of high-quality research studies are the very best way to be able to say to what extent a given treatment can address a condition, symptom, or set of symptoms.  The next best level of evidence is the individual Randomised Controlled Study (RCT) which uses a systematic technique to compare two or more groups of patients receiving different treatments (or a treatment against a “control”, or no treatment).  In acupuncture trials, the nature of the control group is of particular interest as it is hard to blind a patient to whether they are having a needle inserted or not, and even more challenging to blind the researcher/team to this.

The means and quality of how research is carried out varies considerably from country to country, and in terms of how an intervention is compared to another intervention (or a control).  Of note is the fact that “sham” acupuncture (where needles are placed in apparently inert locations rather than traditional acupuncture points) is not really an inert process as it has physiological effects, so that comparing sham and “true acupuncture” may therefore not give a clear picture alone; but and form a part of a research body where acupuncture versus no treatment, vs conventional treatment or vs a different approach/modality also form part of the evidence base.

The n= figure (where quoted in research) tells you how many people were participants in the study, and usually the larger a study (when it is of good quality and design), the more likely it is to be reliable and applicable to larger populations. When (statistical) “significance” is discussed in view of studies it has a very particular meaning – it is the confidence in the data (using statistical tests) that tells us how likely a result could have just come about by chance. The lower the possibility of a chance result, the more likely it is due to the intervention in the experiment. When you are reading a trial/study, the “p” is the number telling us of significance, and this must be under 5% (or p less than 0.05) to mean we can say it is a (statistically) “significant” result.

The Research:

The British Acupuncture Council has a Research digest where they have looked at some more recent studies including on Dyspepsia, including a 2-arm trial where the refractory functional dyspepsia patients were seen to experience improvement in symptoms for up to two months, with no adverse side effects (RCT; n=200) (Zheng et al, 2018).   An RCT in Korea (n=76) looked at functional dyspepsia as well as other quality of life related measures, finding a significant improvement in FD symptoms for up to 8 weeks in the acupuncture group (Ko et al, 2016).  

A meta-analysis of 16 RCTs (n=1436 total) found positive results both for symptoms and quality of life, albeit that the quality of the research was low in many cases in the trails they examined, but further high quality RCT studies are needed to corroborate the trends (Pang et al, 2016). Recently, Zhang at al, (2020) reached a similar conclusion on examining 35 studies (n=3301), specifically recommending multi-centre trials and high quality RCT’s to supplement the current research body.

Mao et al’s meta-analysis (2020; n=853 over 7 RCTs) found Electroacupuncture (EA) to have greater efficacy in alleviating Functional Dyspepsia (FD) symptoms versus placebo (sham-EA). However, with the limitation of small sample size and some low quality, the findings are were cautiously interpreted, calling for further quality, large, multi-centre RCTs to supplement the evidence.

Currently, we await with interest the results of Kwon et al’s (2021) paper after “acupuncture as add-on treatment for functional dyspepsia protocol for systematic review”.

Regarding Your Individual Condition and Symptoms:

Whilst the scientific studies are of great interest to researchers and acupuncturists in terms of comparing protocols, for the patient not versed in research they are less accessible, which is why when we asked “can acupuncture work for my (condition or symptom) we are not able to give a simple yes or no response.  We are able to tell you what experience we have had in our decades of experience in practise, of the types of outcomes we have seen in similar cases, and give you an idea of our level of experience and knowledge in that area, and how this could relate to your own individual situation.  For this, we recommend booking a free telephone consultation where we can answer any questions you have and give a realistic appraisal of what acupuncture may be able to provide.

Headaches – Condition Resources

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

About the research: It is worth noting that in research, randomised controlled studies (RCT) are the most reliable in terms of quality of evidence, with a systematic review or meta analysis of numerous studies being the best way of seeing the overall picture of the state of the evidence. Below we have a selection of the available research, which does include some larger RCTs, and reviews of the literature alongside smaller studies. The n= figure tells you how many people were participants in the study.

Over 80 NHS publications since 2005 have recommended acupuncture both for tension headaches and migraine (and many more worldwide (Birch et al, 2018)

The British Acupuncture Council (BAcC) reviewed the evidence for acupuncture in migraine and tension headaches, where a large number of trials have been carried out, considerably more effective than placebo (Tavola et al, 1992.) The BAcC concluded there was some evidence that acupuncture has a significant therapeutic effect on symptoms such as pain and frequency in migraine attacks. It was also noted in a crossover research trial that in addition to demonstrating a significant effect in reduction of frequency of attacks and their duration, that acupuncture has a very low side effect profile (Hesse et al, 1994; Loh et al, 1984).

The British Acupuncture Council has a Research digest where they examined some recent studies on headache and migraine, as well as an evidence based factsheet (links are below).

Acupuncture has had a good profile for both migraine and tension headaches since the Cochrane review of 2009, which was updated in 2016 (Linde et al), including 22 trials (n=4985), finding evidence to suggest that adding acupuncture to symptomatic treatment of attacks reduces the frequency of headaches.  The researchers expressed the need for further long term trials in this area.

The current NICE headache guidelines (2012; 1.3.9) state the following: “Prophylactic treatment: Consider a course of up to 10 sessions of acupuncture over 5 to 8 weeks for the prophylactic treatment of chronic tension‑type headache.”

A randomised controlled trial (n=74), looking at chronic daily headaches (CDL), concluded that supplementing medical management with acupuncture, improved health-related quality of life, and patients’ perception that they suffered less from headaches (Coeytaux et al, 2005).

A large UK RCT (n=401) concluded that “Acupuncture leads to persisting, clinically relevant benefits for primary care patients with chronic headache, particularly migraine. Expansion of NHS acupuncture services should be considered” (Vickers et al, 2004).  Furthermore, the researchers found that in comparison to controls, the acupuncture patients used 15% less medication; made 25% fewer visits to GPs and took 15% fewer days off sick.

A systematic review on migraine without aura (Xu et al, 2018) examined 14 RCTs (n=1155), drawing the conclusion that acupuncture is safe, more beneficial that sham control in addressing symptoms, although they were reserved in the strength of this finding by the quality of some of the evidence available, meaning further studies were warranted.

A recent Randomised Controlled Trial (RCT) for acupuncture for Chronic Tension-Type Headache (N=218) used sham vs true acupuncture providing an 8 week treatment course; this study showed long-term effective prophylaxis (prevention of headaches) as the outcome, and used a 32 week follow up (Zheng at al (2022).

Tao et al (2023)’s a systematic review and meta-analysis looking at prevention of tension-type headaches (TTH) using a large sample size (n=2795; 14 RCT studies) published in the Journal of Neurology showed the efficacy of acupuncture for tension-type headache prophylaxis, whereby the acupuncture groups had more reduction than sham acupuncture in TTH frequency, both after treatment and at follow-up. The researchers concluded acupuncture to be effective and safe for TTH prevention, but noted some limitations in evidence quality, and suggested further high-quality trials to supplement the current evidence.

Ambrosie et el, (2012) looked at cost effectiveness of acupuncture use in this field, using the NHS measure of cost per quality adjusted life year (QALY) gain from treatment usage, finding  acupuncture to be cost effective by this measure.

As far back as 1999, a systematic review of 22 trials (Melchart et al, 1999; n=1042), concluded that the existing evidence suggested acupuncture had a role in the treatment of recurrent headaches. A team with the same lead researcher went on, in 2003, to compare acupuncture with the use of the drug sumatriptan (6 mg subcutaneously), and placebo injection, in an RCT (n=179), in early treatment of an acute migraine attack.   The main outcome measure was the number of patients in whom a full migraine attack was prevented, and both acupuncture and sumatriptan were more effective than a placebo injection in the early treatment of an acute migraine attack. When an attack could not be prevented, sumatriptan was more effective than acupuncture at relieving headache, but had less side effects than did the drug.  They acknowledged that the practicality of providing acupuncture in an outpatient setting at the onset was more difficult than the use of drugs, but highlighted its positive role in the prevention (prophylaxis) of attacks (Melchart et al, 2003).

Mechanisms of action:

Acupuncture studies have shown it can: provide pain relief by stimulating nerves in body tissues and leading to endorphin release (natural painkilling substances), as well as downregulating the brain and nervous system’s reaction to stress and pain (Zhao 2008; Zijlstra et al, 2003; Pomeranz, 1987).

Acupuncture stimulates the body to create its own natural painkilling substances, such as Beta Endorphins (β-Endorphin). In studies acupuncture has been shown to stimulate the production of natural painkillers called opioid-like peptides (OLPs), including β-Endorphin: For example, this was shown in an RCT in 90 patients with a range of painful disorders (Petti et al, 1998). The same study showed acupuncture also and enhanced the activity of immune cells (lymphocytes, natural killer cells and monocytes) that help fight infections and diseases (Petti et al, 1998).

Zijlstra et al (2003) reviewed the effects and mechanisms of acupuncture in treating various inflammatory diseases and conditions. They proposed the mechanisms of action:

  • Acupuncture may release neuropeptides from nerve endings that have vasodilative and anti-inflammatory effects through CGRP.
  • Acupuncture may also interact with substance P, which is involved in pain transmission and inflammation.
  • Acupuncture may contribute to analgesia by stimulating the release of β-endorphin, which binds to opioid receptors and inhibits pain signals.
  • Acupuncture may influence the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines such as TNF-α and IL-10.

Acupuncture can activate mast cells at acupoints, which release histamine, serotonin, adenosine, and other mediators that modulate nerve transmission and inflammation (Li et al, 2022)

Acupuncture has been shown in animal models to promote the release of factors that involved in the reduction of inflammation (vascular and immunomodulatory factors – (Kim et al, 2008; Kavoussi and Ross, 2007 [review article]; Zijlstra et al, 2003), and also to affect levels of serotonin (in an animal model), and other peptides in the brain and nervous system and modulate blood flow in the brain and elsewhere in the body, in humans (Zhong and Li, 2007; Shi et al, 2010; Park, 2009).

Constipation – Condition Resources

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

A scholarly search of the available research papers on the terms “acupuncture” + “constipation” yields over 27,500 papers, and narrowing this to “RCT” to identify Randomised Controlled Trials, gives over 2,900 results; of which 43% have been carried out since 2017 (Google Scholar). This suggests that acupuncture is being used traditionally and currently in this area, much research has been carried out, and that the pace of research here has increased in recent years, meaning the research community recognise its potential role is worthy of appraisal in a scientific manner.

Interpreting the research:

When reading health research, it is important to know that Systematic Reviews or Meta Analyses of a large number of high-quality research studies are the very best way to be able to say to what extent a given treatment can address a condition, symptom, or set of symptoms.  The next best level of evidence is the individual Randomised Controlled Study (RCT) which uses a systematic technique to compare two or more groups of patients receiving different treatments (or a treatment against a “control”, or no treatment).  In acupuncture trials, the nature of the control group is of particular interest as it is hard to blind a patient to whether they are having a needle inserted or not, and even more challenging to blind the researcher/team to this.

The means and quality of how research is carried out varies considerably from country to country, and in terms of how an intervention is compared to another intervention (or a control).  Of note is the fact that “sham” acupuncture (where needles are placed in apparently inert locations rather than traditional acupuncture points) is not really an inert process as it has physiological effects, so that comparing sham and “true acupuncture” may therefore not give a clear picture alone; but and form a part of a research body where acupuncture versus no treatment, vs conventional treatment or vs a different approach/modality also form part of the evidence base.

The n= figure (where quoted in research) tells you how many people were participants in the study, and usually the larger a study (when it is of good quality and design), the more likely it is to be reliable and applicable to larger populations. When (statistical) “significance” is discussed in view of studies it has a very particular meaning – it is the confidence in the data (using statistical tests) that tells us how likely a result could have just come about by chance. The lower the possibility of a chance result, the more likely it is due to the intervention in the experiment. When you are reading a trial/study, the “p” is the number telling us of significance, and this must be under 5% (or p less than 0.05) to mean we can say it is a (statistically) “significant” result.

The Research:

The British Acupuncture Council has a Research digest where they examined some recent studies on constipation including an RCT taken in 15 hospitals in China (n=1075) where the acupuncture group was seen to increase the number of weekly spontaneous bowel movements, with the researchers recommending that further studies are needed to see the longer term outcomes (Liu et al, 2016). 

Another RCT (Zheng et al, 2018; n=684) similarly showed promise in this area, but was limited somewhat by its design in not having a sham acupuncture control (they only had three different types of verum acupuncture compared with pharmacological intervention), meaning it was difficult to know the magnitude of the effect.

A systematic review and meta-analysis of 33 trials (n=4324 total; Zheng et al, 2019) compared eight different non-drug treatments, finding acupuncture and TENS were the most effective in addressing chronic functional constipation symptoms, but interpreting the results with caution due to small study effects. A later systematic review, (Wang et al, 2020) drew similar conclusions, noting increased quality of life in acupuncture groups as well as trends towards symptomatic relief, but noting evidence quality was low, warranting further studies (28 RCT’s; n=3525). A smaller systematic review of electro-acupuncture in this field drew similar conclusions to the above in terms of positive yet tentative trends (Zhang et al, 2020; 6 studies, n=1457).

Research continues, and a number of protocols for systematic reviews in this area have been published recently, the results of which are awaited with interest: e.g. Zhu et al, 2021; Yang et al, 2020; and Chen et al, 2020.

Regarding Your Individual Condition and Symptoms:

Whilst the scientific studies are of great interest to researchers and acupuncturists in terms of comparing protocols, for the patient not versed in research they are less accessible, which is why when we asked “can acupuncture work for my (condition or symptom) we are not able to give a simple yes or no response.  We are able to tell you what experience we have had in our decades of experience in practise, of the types of outcomes we have seen in similar cases, and give you an idea of our level of experience and knowledge in that area, and how this could relate to your own individual situation.  For this, we recommend booking a free telephone consultation where we can answer any questions you have and give a realistic appraisal of what acupuncture may be able to provide.

Useful pages: Stroke ; Angina, Arrhythmias, Coronary Heart Disease, and Heart Failure

Research and Resources on Blood Pressure, Hypertension and Acupuncture:

A scholarly search of the available research studies on “acupuncture” + “blood pressure” reveals over 43,400 papers from journals, and narrowing this to “RCT” leads to over 4,500 hits, of which 37% have been carried out since 2017.  A scholarly search of the available research studies on “acupuncture and hypertension” reveals over 44,500 papers from journals, and narrowing this to “RCT” leads to over 4,500 hits, of which 40% have been carried out since 2017.  This indicates the extent to which acupuncture is used traditionally and currently in this area; with scientific research increasing in pace and demonstrating an area worthy of scientific appraisal and consideration.

When you are reading a trial/study, the “p” is the number telling us of significance, and this must be under 5% (or p less than 0.05) to mean we can say it is a (statistically) “significant” result.

The Research:

Hypertension is a common cardiovascular disease that affects about one billion people worldwide. 

A meta-analysis of studies compared approaches to treating essential hypertension (31 trials; n=2649; Tan et al, 2019), concluded that acupuncture may be useful in addressing hypertension, albeit that quality of the studies was limited and further research was warranted.  Another analysis of 10 trials in BP amongst stroke patients  (Hong et al, 2020; n=847) concluded that acupuncture may be a suitable treatment option for regulating BP after stroke but also noted the low-quality in the data and as need for further well-designed trials.

Niu et al, (2019) examined 13 systematic reviews of 14 non-drug therapies (including acupuncture) in addressing high blood pressure.  They concluded that massage and acupuncture plus an antihypertensive drug may benefit people who wanted to lower their blood pressure; once again methodological issues around available research limited the strength of the recommendations.

Li et al, 2014 carried out a systematic review and meta-analysis of 4 RCTs (n=386) that compared acupuncture with sham acupuncture for treating essential hypertension, in order to assess the effectiveness and safely of acupuncture as an adjunctive approach for the condition, using statistical methods to pool the results and compare the average blood pressure changes between the groups.  Acupuncture was found to significantly lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients taking antihypertensive medications, but not in patients who were not taking medications.  Acupuncture was generally safe and well-tolerated, with only minor adverse events reported.  The authors concluded that acupuncture could be a promising adjunctive therapy for hypertension, but more large-scale and long-term trials are needed to confirm its efficacy and safety.

Acupuncture was found to be a promising adjunctive therapy for essential hypertension in Yin et al’s (2007) a double-blind, randomized, controlled trial, where acupuncture was assessed for its benefits as an add-on to conventional antihypertensive managements such as medication or lifestyle modification on patients with high blood pressure.  In the small (n=30) study, the real acupuncture group showed a significant decrease in mean BP after 8 weeks.  Auricular (ear) acupuncture has also been shown to reduce preoperative blood pressure (BP) elevation in different age groups in a prospective RCT (Ma et al, 2023; n=120).

Mechanism of action:

Animal model studies have shown physiological effects from auricular (ear) acupuncture on the Heart point, whereby using this point regulates cardiovascular function (heart rate, blood pressure). Cardiac related nerve cells were shown to be regulated by the use of Heart (auricular point), lowering blood pressure in the arteries, by means of activating a certain type of nerve cell receptor (baroreceptor sensitive neurons) in part of the brainstem (nucleus tractus solitarius) (Gao et al, 2011).

Acupuncture has been shown in many mechanism-of-action trials to be sympathoinhibitory (able to downregulate the sympathetic nervous system) and lower the stress response in brain and nervous system (Middlekauff et al, 2002).

Li et al (2014) proposed a possible mechanism of action for the lowering of blood pressure, in that acupuncture could regulate the renin-angiotensin-aldosterone system (RAAS), which is involved in blood pressure regulation, by stimulating specific acupoints that correspond to the kidney and liver meridians. The other mechanism is based on the Western medicine theory of modulating the autonomic nervous system (ANS), which controls the heart rate and vascular tone. They further hypothesized that acupuncture might activate the parasympathetic branch of the ANS, thus lowering the sympathetic activity and reducing the release of stress hormones that constrict the blood vessels.

Regarding Your Individual Condition and Symptoms:

Whilst the scientific studies are of great interest to researchers and acupuncturists in terms of comparing protocols, for the patient not versed in research they are less accessible, which is why when we asked “can acupuncture work for my (condition or symptom) we are not able to give a simple yes or no response.  We are able to tell you what experience we have had in our decades of experience in practise, of the types of outcomes we have seen in similar cases, and give you an idea of our level of experience and knowledge in that area, and how this could relate to your own individual situation.  For this, we recommend booking a free telephone consultation where we can answer any questions you have and give a realistic appraisal of what acupuncture may be able to provide.

Bladder Issues – Condition Resources

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

Incontinence and bladder issues may be caused by structural issues, pregnancy and post-partum, overactive bladder in women, and in men there may be issues caused by prostatitis or oncology treatment following prostate cancer impacting upon the bladder function.  Bladder function can also be affected after someone has had a stroke, or related to chronic health conditions.

Research and Resources on Bladder (Urinary System) Issues and Acupuncture:

A scholarly search of the available research studies on “acupuncture” + “urinary”* reveals over 32,000 papers from journals, and narrowing this to “RCT” leads to over 3,400 hits, of which 39% have been carried out since 2017.  From this we can deduce that acupuncture is being used, traditionally and currently in this area; scientific research is being conducted in this area at an increasing pace -indicating an area worthy of scientific appraisal and consideration.  (*We did not use the search term “bladder” as this is an acupuncture meridian and point location name and would otherwise bring up articles that mention these acupoints, as well as those to do with bladder conditions).

Up to 6% of adult women experience up to 3 episodes of acute lower urinary tract infections (UTIs) annually (Alreak & al, 2002). A common issue, millions of women in the receive antibiotic treatment every year, and with raising concerns of antibiotic resistance in pathogens, alternate ways to look at this issue are warranted

Interpreting the research:

When reading health research, it is important to know that Systematic Reviews or Meta Analyses of a large number of high-quality research studies are the very best way to be able to say to what extent a given treatment can address a condition, symptom, or set of symptoms.  The next best level of evidence is the individual Randomised Controlled Study (RCT) which uses a systematic technique to compare two or more groups of patients receiving different treatments (or a treatment against a “control”, or no treatment).  In acupuncture trials, the nature of the control group is of particular interest as it is hard to blind a patient to whether they are having a needle inserted or not, and even more challenging to blind the researcher/team to this.

The means and quality of how research is carried out varies considerably from country to country, and in terms of how an intervention is compared to another intervention (or a control).  Of note is the fact that “sham” acupuncture (where needles are placed in apparently inert locations rather than traditional acupuncture points) is not really an inert process as it has physiological effects, so that comparing sham and “true acupuncture” may therefore not give a clear picture alone; but and form a part of a research body where acupuncture versus no treatment, vs conventional treatment or vs a different approach/modality also form part of the evidence base.

The n= figure (where quoted in research) tells you how many people were participants in the study, and usually the larger a study (when it is of good quality and design), the more likely it is to be reliable and applicable to larger populations. When (statistical) “significance” is discussed in view of studies it has a very particular meaning – it is the confidence in the data (using statistical tests) that tells us how likely a result could have just come about by chance. The lower the possibility of a chance result, the more likely it is due to the intervention in the experiment. When you are reading a trial/study, the “p” is the number telling us of significance, and this must be under 5% (or p less than 0.05) to mean we can say it is a (statistically) “significant” result.

The Research:

Stress Incontinence and overactive bladder:

A large, multicentre RCT (China: 12 hospitals; n=504) for women with stress incontinence showed that the electroacupuncture group experienced less urine leakage after 6 weeks of treatment, than did the sham electroacupuncture control group (Liu et al, 2017).  A further systematic review (Zhao 2018; 10 trials; n=794), showed acupuncture (in particular electroacupuncture) as more effective than sham in decreasing nocturia (night-time incontinence), relieving voiding symptoms, decreasing micturition and incontinence frequency, and enhancing quality of life

A small Chinese (n-71) randomised controlled trial for female stress urinary incontinence compared acupuncture plus pelvic floor muscle exercises with the exercises alone.  All outcomes improved significantly in both groups, with the total effective rate being higher in the acupuncture group than in the control group, along with improves quality of life scores.  A systematic review of treatment of overactive bladder, urge urinary incontinence, and related symptoms (Hartmann et al, 2009; 232 studies) acupuncture was the sole complementary treatment that showed early evidence of benefit.

Forde et al (2016), in a literature review in the International Urogynecology Journal, stated existing studies showed promise for suggesting a role for acupuncture in addressing overactive bladder issues, however there were limitations in the research design, and further well-designed studies should follow to corroborate this.

In other studies, acupuncture treatment significantly reduced the frequency of urinary incontinence compared to a control group (Kim et al, 2008; n=52); a statistically significant difference was found in favour of acupuncture compared to “western” medicine for post-apoplectic urinary issues (Liu et al, 2008); and bladder-specific acupuncture treatments resulted in significant improvements in bladder capacity, urgency, frequency, and quality-of-life scores when compared with placebo acupuncture treatments in a randomised controlled trial (Emmons et al, 2005; n=85).

For Overactive Bladder, Aydoğmuş et al, (2014; RCT; N=82) looked at Urine Nerve Growth Factor (NGF) as a biomarker regarding acupuncture’s effect on bladder function. NGF is a chemical messenger in the body and related to the smooth muscle and urothelium (lining of the urinary tract). Comparing drug treatment solifenacin with acupuncture in two groups, they concluded that “In patients with OAB in whom anticholinergic treatment is contraindicated, acupuncture may be considered another treatment option.” NGF has been shown in a number of studies, to be mediated, normalised by acupuncture.

Acupuncture on the sacral vertebrae (spinal area at the sacrum); the area where nerves suppling the bladder emerge; has been shown to suppress bladder activity, as well as to suppress activity in the areas of the brainstem related to micturition (urination), this in turn could suppress/normalise overactivity of bladder contraction (Wang et al, 2012).

Objective (scientifically measurable) improvements from acupuncture have also been seen in urodynamic studies on females with frequency, urgency and dysuria (Chang, 1988; n=52). Urodynamic studies are medical tests measuring lower urinary tract function. Per Chang in the American Urological Association Journal of Urology : “Our studies indicated that acupuncture could be used as a simple and effective method to treat female patients with frequency, urgency and dysuria”.

More information on acupuncture and the Urinary System is available on out page here

Diabetic neurogenic bladder:

A randomised controlled trial (n=70) compared acupuncture plus the drug methycobal, with the drug alone. The acupuncture plus methycobal group saw significant improvement in the rate of urgency of urination, frequency of micturition, dribbling urination, urinary incontinence and dysuria, than did the drug alone group.  A combined approach was therefore advocated, with acupuncture improving the drug action (Tian et al, 2007)

Post-Stroke:

Acupuncture has been tentatively shown to have positive results for urinary incontinence post-stroke in a systematic review (Thomas, 2008; n=724 from 12 trials, of which 3 were acupuncture trials), although further trials for acupuncture in this field are warranted, due to the low number and quality of the research studies available at the time of the review.  A randomised controlled trial (n=58)  found the moxibustion group (an acupuncture adjunct treatment) had greater improvement in urinary symptoms than the control group (Yun et al, 2007).  In a large study in Taiwan, stroke patients in hospital who received acupuncture treatment experienced a lower incidence of urinary tract infections than did those who didn’t receive acupuncture (Yang et al, 2019)

Bed-wetting in children:

There was some evidence from a systematic review (Bower et al, 2005; 11 studies), that acupuncture could be useful for nocturnal enuresis (bed-wetting) in children when used in conjunction with other treatment, although further trials are warranted due to the low methodological quality of the research studies available at the time.

Post Hysterectomy:

A randomised controlled trial (n=110) examined electroacupuncture on recovery of urinary bladder function after radical hysterectomy.  The electroacupuncture group experienced faster improvement of recovery of bladder function, greater improvement of dynamic indexes, fewer days in hospital after surgery and a reduced likelihood of bladder infection than did the control group.

Urinary tract infection (cystitis):

A randomised controlled trial (Qin et al, 2020; n=341) found acupuncture appeared to be beneficial for treatment and prevention of recurrent UTIs, but also noted limitations in the current evidence. The researchers noted the increasing problem of antibiotic resistance, meant such research becomes increasingly important in the overall approach.

From the guidelines The Society of Obstetricians and Gynaecologists of Canada: “Acupuncture may be considered as an alternative in the prevention of recurrent urinary tract infections in women who are unresponsive to or intolerant of antibiotic prophylaxis.” (Epp and Larochelle, 2017).

Alraek et al (2002) concluded from their small RCT (n=100): “our results, as well as previous findings, indicate that acupuncture treatment may be effective in preventing recurrent lower UTIs in healthy adult women.” This echoed the small Norweigan study (N=67) which concluded that acupuncture seems a worthwhile alternative approach in the prevention of recurring lower UTI in women (Aune et al, 1998).

Prostatitis related bladder symptoms:

Pan et al (2023) in the Journal of Pain Research and Management, looked at the efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), a complex male dysfunction that affects the quality of life. They compared acupuncture with western medicine and sham acupuncture in high quality randomized controlled trials (RCTs).  Outcome measures included pain score, urinary symptom score, NIH-CPSI (prostatitis symptom score), quality of life score, and efficacy rate.  Acupuncture was found superior to western medicine and sham acupuncture in improving all outcome measures.  This was a relatively small review (10 RCTs; n=798) and the team called for further future research, to supplement the evidence body.

In a review of the literature, acupuncture was found to be beneficial in reducing the symptoms of prostatitis, including urinary symptoms (Franco et al, 2019). 

Mechanisms of action of acupuncture in the urinary system:

Initial animal studies suggest a number of biochemical mechanisms of action involved the effect of acupuncture on suppressing overactive bladder (Forde et al, 2016). Physiological/animal studies have shown acupuncture to decrease the expression of a relevant biomarker (c-Fos) in the brain, along with associated reduction in stress urinary incontinence (Chung et al, 2008).

Acupuncture was also found in physiological studies to influence nitrergic neurotransmitters, which raises nitric oxide levels in bladder tissue and causes smooth muscle relaxation, leading to increased bladder capacity (Chen 2006). 

Acupuncture stimulates the body to create its own natural painkilling substances, such as Beta Endorphins (β-Endorphin). In studies acupuncture has been shown to stimulate the production of natural painkillers called opioid-like peptides (OLPs), including β-Endorphin: For example, this was shown in an RCT in 90 patients with a range of painful disorders (Petti et al, 1998). The same study showed acupuncture also and enhanced the activity of immune cells (lymphocytes, natural killer cells and monocytes) that help fight infections and diseases (Petti et al, 1998).

Regarding Your Individual Condition and Symptoms:

Whilst the scientific studies are of great interest to researchers and acupuncturists in terms of comparing protocols, for the patient not versed in research they are less accessible, which is why when we asked “can acupuncture work for my (condition or symptom) we are not able to give a simple yes or no response.  We are able to tell you what experience we have had in our decades of experience in practise, of the types of outcomes we have seen in similar cases, and give you an idea of our level of experience and knowledge in that area, and how this could relate to your own individual situation.  For this, we recommend booking a free telephone consultation where we can answer any questions you have and give a realistic appraisal of what acupuncture may be able to provide.

Allergies – Condition Resources

Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.

About the research:

When reading health research, it is important to know that Systematic Reviews or Meta Analyses of a large number of high-quality research studies are the very best way to be able to say to what extent a given treatment can address a condition, symptom, or set of symptoms.  The next best level of evidence is the individual Randomised Controlled Study (RCT) which uses a systematic technique to compare two or more groups of patients receiving different treatments (or a treatment against a “control”, or no treatment).  In acupuncture trials, the nature of the control group is of particular interest as it is hard to blind a patient to whether they are having a needle inserted or not, and even more challenging to blind the researcher/team to this.

The means and quality of how research is carried out varies considerably from country to country, and in terms of how an intervention is compared to another intervention (or a control).  Of note is the fact that “sham” acupuncture (where needles are placed in apparently inert locations rather than traditional acupuncture points) is not really an inert process as it has physiological effects, so that comparing sham and “true acupuncture” may therefore not give a clear picture alone; but and form a part of a research body where acupuncture versus no treatment, vs conventional treatment or vs a different approach/modality also form part of the evidence base.

The n= figure (where quoted in research) tells you how many people were participants in the study, and usually the larger a study (when it is of good quality and design), the more likely it is to be reliable and applicable to larger populations. When (statistical) “significance” is discussed in view of studies it has a very particular meaning – it is the confidence in the data (using statistical tests) that tells us how likely a result could have just come about by chance. The lower the possibility of a chance result, the more likely it is due to the intervention in the experiment. When you are reading a trial/study, the “p” is the number telling us of significance, and this must be under 5% (or p less than 0.05) to mean we can say it is a (statistically) “significant” result.

The Research:

A scholarly search on “allergies” + “acupuncture” reveals over 3,400 papers, and narrowing to Randomised Controlled Trials (RCT’s) reveals over 369 results (Google Scholar). This shows that acupuncture is being used traditionally and currently in this area, and that it has been recognised there is a need to research it a scientific manner.

Allergic Asthma:

A large, randomised controlled research study in Germany (Brinkhaus et al 2017; n=1445) showed that up to 15 sessions of acupuncture given in addition to routine care increased both disease specific, and health related quality of life, when compared to the group who received routine care alone.

Allergic Dermatitis:

In an animal model study, acupuncture treatment was shown to inhibit swelling of the ears and ear weight in mice with oxazolone-induced skin allergic dermatitis, compared to non-acupuncture treatment (Okumura et al, 2002), and lower levels of inflammatory markers (serum and ear tissue cytokines) were also lowered in the acupuncture group.

A forthcoming systematic review protocol has been published with the aim of evaluating the efficacy and safety of acupuncture in the treatment of atopic dermatitis (protocol: Lee et al, 2019). This is another growing research area, of 451 RCT’s ever published on this, 180 have been carried out since 2017.

Chronic Pruritus:

More generally, for chronic pruritus, a condition of chronic itching that can be caused by different disease states and which adversely affects quality of life, a systematic review is awaited, the protocol having been published in the BMJ Open recently (protocol: Zhang et al, 2020).

Atopic Eczema:

A systematic review (Jiao et al, 2020) looked at 8 RCT’s (n=434), and despite some methodological limitations were able to conclude acupuncture may decrease itch sensitivity and improve the global symptoms of atopic eczema.

The results of a small (n=10), randomised controlled trial (Pfab et al, 2011), suggested acupuncture reduced itch intensity and the expression of certain immune factors (basophils) in patients with atopic eczema. The acupuncture group showed less CD63 positive basophils (allergy markers in the body) and rated mean itch intensity significantly lower than did the control group after exposure to allergens (house dust mite and timothy grass pollen).  Pfab et al 2010 (n=30) had also found that after an allergen stimulus (house mite or grass pollen skin prick), the size of the wheal and flare at the skin site were smaller in the group receiving preventative acupuncture than in the control (no acupuncture) and placebo (non-specific acupuncture points used) groups, suggesting that the actual points used are also relevant and not just the overall action of needling.  Mean itch ratings were also lower once again in the true acupuncture group.

Allergic Rhinitis (Hayfever):

The British Acupuncture Council has a Research digest where they examined some recent studies on Allergic Rhinitis, with an overall trend that acupuncture was found beneficial, comparing favourably with antihistamine use.  A review of the literature (Taw et al, 2015) found that high-quality RCTs demonstrated efficacy and effectiveness of acupuncture in this condition, and also was beneficial in terms of quality of life measures, the researchers also stated that further high quality studies are desirable in this area due to some methodological limits on study designs.  

Feng et al, (2015) carried out a systematic review and meta-analysis of acupuncture in allergic rhinitis, entailing 13 papers (N=2365 in total); the researchers stated this was a safe intervention which gave improvement in the Rhinitis Quality of Life Questionnaire (RQLQ) scores of the participants in the acupuncture groups.

Two studies have also established cost effectiveness of acupuncture in allergic rhinitis; Kim et al, (2012) carried out a systematic review of 17 RCTs using the quality-adjusted life years (QALYs) measure the NHS uses, demonstrating that as well as offering benefits, these were value for money where acupuncture was used.  Witt and Brinkhaus (2010) reached a similar conclusion but more tentatively, calling for further studies to establish this.

McDonald et al (2013) reviewed the pathophysiology of allergic rhinitis and the acupuncture research body in this area.  Acupuncture has been shown to improve clinical outcomes in patients with allergic rhinitis by modulating immune response and reducing inflammation.  Per the review of RCTs, acupuncture may down-regulate Th2 and proinflammatory cytokines, proinflammatory neuropeptides (such as SP, CGRP and VIP) and neurotrophins (such as NGF and BDNF) in allergic rhinitis. Acupuncture may also inhibit histamine-induced itch and TRPV1 signalling, which mediate some of the symptoms of allergic rhinitis.

According to a systematic review and meta-analysis by Yin et al (2020: 39 studies; n=4413) acupuncture can significantly improve the symptoms and quality of life of patients with allergic rhinitis. The authors searched various databases and included 30 randomized controlled trials with 4413 participants. They found that acupuncture improved the nasal symptoms and quality of life of patients with allergic rhinitis, compared to no intervention, sham acupuncture, or conventional medication. They also reported that acupuncture had a better safety profile than medication.

Possible mechanisms of action in allergy:

A review article (Kavoussi & Ross, 2007) suggests that the anti-inflammatory actions that have been demonstrated to be brought about by acupuncture may be mediated via activation of the vagus nerve, alongside deactivation of inflammatory macrophages and other proinflammatory cytokines.  The researchers concluded that “The use of acupuncture as an adjunct therapy to conventional medical treatment for a number of chronic inflammatory and autoimmune diseases seems plausible and should be validated by confirming its cholinergicity”.  Other studies (Zijlstra et al, 2003) have revealed that acupuncture some of the pain modulating and anti-inflammatory effects exhibited in acupuncture may be due to the fact that it has been shown to stimulate certain substances in the body which act as vasodilators, neurotransmitters and painkillers (beta-endorphins, CGRP and substance P) and further stimulate cytokines and nitric oxide, all of which play roles in inflammatory states. 

Acupuncture can activate mast cells at acupoints, which release histamine, serotonin, adenosine, and other mediators that modulate nerve transmission and inflammation (Li et al, 2022)

Zijlstra et al (2003) reviewed the effects and mechanisms of acupuncture in treating various inflammatory diseases and conditions. They proposed the mechanisms of action:

  • Acupuncture may release neuropeptides from nerve endings that have vasodilative and anti-inflammatory effects through CGRP.
  • Acupuncture may also interact with substance P, which is involved in pain transmission and inflammation.
  • Acupuncture may contribute to analgesia by stimulating the release of β-endorphin, which binds to opioid receptors and inhibits pain signals.
  • Acupuncture may influence the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines such as TNF-α and IL-10.

CSR and ERP are blood tests related to the functioning of the immune system, that can measure and monitor inflammation in the body.  They are relevant to conditions such as Rheumatoid Arthritis, and other immune and inflammatory conditions.  Per a review by Feng at al, (2023) electroacupuncture (EA) plus medication had a significant effect in lowering both ESR and CRP levels in patients with RA compared with medication alone.  These results suggest that EA may have an anti-inflammatory effect and improve the immune status of patients with RA.

In an animal study, Sun et al, (2023) were able to show that electroacupuncture worked by blocking a pathway in the synovium called TLR2/4, that activates immune response and inflammation.  The researchers therefore suggested the anti-inflammatory and analgesic effects of EA were related to the inhibition of TLR2/4 signalling on synovial fibroblasts and macrophages.

Wei et al, 2015 investigated the effect of acupuncture on airway inflammation and immune responses in mice with experimental asthma. Acupuncture was effective in reducing airway hyperresponsiveness (AHR); lung inflammation; mucus secretion; and inflammatory markers including Th17 cytokines and NF-κB pathway, in the asthma model. Additionally, acupuncture increased the number and function of Treg cells – a type of white blood cell that can suppress inflammation and prevent autoimmunity.  The article suggests that acupuncture may be a useful complementary therapy for asthma patients due to anti-inflammatory and immune modulation effects.

Liu et al (2014) investigated the anti-inflammatory effect of electroacupuncture (EA) in a rat tissue chamber model of inflammation. The study found that EA inhibited the p65 protein from moving to the cell nucleus to activate inflammatory genes.  EA also increased the expression of IκBα, which binds to NF-κB and preventing it from entering the nucleus to activate inflammatory genes. These interfere with the IκB/NF-κB pathway that regulates inflammation, indicating one of the mechanisms of acupuncture in modulating immune / inflammatory response.

Wang et al (2023) reviewed evidence from animal and human studies regarding the immunomodulatory mechanism of acupuncture, regarding its effects on different components of the immune system, such as mast cells, macrophages, neutrophils, natural killer cells, astrocytes, microglia, CD4+ and CD8+ T cells, and cytokines.  They detailed the neuroanatomical mechanisms of acupuncture in immunomodulation, such as the vagal-adrenal pathway, the cholinergic anti-inflammatory pathway, the spinal sympathetic pathway, the brain-gut axis, and the hypothalamus-pituitary-adrenal axis.  They concluded that studies to support the role of acupuncture in regulating inflammation, infection, allergy, pain, and tissue repair.

Per MacDonald et al (2015), acupuncture may:

  • reduce inflammation and nasal congestion by downregulating proinflammatory neuropeptides, cytokines, and neurotrophins
  • modulate immune function by altering the balance of Th1 and Th2 cells and suppressing mast cell degranulation
  • influence various receptors and signalling pathways that are involved in inflammatory response, such as TRPV1, opioid, chemokine, dopamine, and cannabinoid receptors
  • activate a novel cholinergic anti-inflammatory pathway that involves vagal and sciatic nerves and is mediated by dopamine

Electroacupuncture (EA) has been shown in a rat model (Li et al, 2008) to have anti-inflammatory benefits by modulating the hypothalamic-pituitary-adrenal (HPA) axis, (HPA axis regulates the stress response and immune function).  Specifically, Li et al outlined that EA sets off a cascade in the brain (via corticotropin-releasing hormone, and adrenocorticotropic hormone) to produce cortisol, which reduces inflammation and oedema.


Regarding Your Individual Condition and Symptoms:

Whilst the scientific studies are of great interest to researchers and acupuncturists in terms of comparing protocols, for the patient not versed in research they are less accessible, which is why when we asked “can acupuncture work for my (condition or symptom) we are not able to give a simple yes or no response, we are able to tell you in the decades of experience we personally have at the clinic of the types of outcomes we have seen in similar cases, and give you an idea of our level of experience and knowledge in that area, which is why the research data do not tell the whole story and if you want to find out more specific information in how this could relate to your own individual situation, we recommend booking a free telephone consultation where we can answer any questions you have and give a realistic appraisal of what acupuncture may be able to provide.
