Since more than 20 years, I have been writing about the risks of alternative therapies. One of my first papers on this issue was published in 1995 and focussed on acupuncture. Here is its abstract:

The use of acupuncture is widespread. The procedure is often claimed to be totally, or at least reasonably, safe. The published evidence regarding its potential risks is reviewed. The repeated and/or inappropriate use of an acupuncture needle carries the risk of infections. Amongst others, AIDS and hepatitis have been transmitted. Acupuncture needles may also traumatise tissues and organs. Pneumothorax is the most frequent complication caused in this way. Finally, needles may break and fragments can be dislodged into distant organs. A serious and more general concern related to the safety of acupuncture is the competence of the therapist, whether or not medically qualified. The “philosophy” of acupuncture is not in line with orthodox diagnostic skills; therefore acupuncturists can be dangerously unconcerned with diagnostic categories. Thus indirect risks might add significantly to the direct risks of acupuncture. It is concluded that the true risk of acupuncture cannot be estimated. Whatever its extent, it could and probably should be lowered by enforcing educational and clinical standards.

My reason for banging on about the potential harms (direct and indirect risks) of alternative medicine is fairly obvious: I want to alert healthcare professionals and consumers to the fact that these treatments may not be as harmless as they are usually advertised to be. Yet, I have often be called an alarmist fear-monger. In my view, nothing could be further from the truth.

Thinking about fear-mongering, I began to ask myself whether those who regularly accuse me are the ones guilty of the deed. Are alternative practitioners fear-mongers? Surely not all of them, but some clearly are. Here are a few of the strategies they use for their fear-mongering.


Perhaps the most obvious way to instil fear into people is to tell them that they are affected by a disease or condition they do not have. Many alternative practitioners do exactly that!

  • A chiropractor might tell you that you have a subluxation in your spine.
  • A naturopath would inform you that your body is full of toxins.
  • An acupuncturist will tell you that your life energy is blocked.
  • A homeopath might warn you that your vital force is too low.

These diagnoses have one thing in common: they do not exist. They are figments of the therapist’s imagination. And they have another thing in common: the abnormalities need to be corrected, and – surprise, surprise – the very therapy that the practitioner specialises in happens to be just the ticket for that purpose.

  • The chiropractor will tell you that a simple spinal adjustment will solve the problem.
  • The naturopath will inform you that a bit of detox will eliminate the toxins.
  • The acupuncturist will tell you that his needles will de-block your chi.
  • The homeopath will persuade you that he can find the exact remedy to revive your vital force.

And there we have the third thing these diagnoses have in common: they are all treatable, will all result in a nice bill, and will all improve the cash-flow of the therapist.


But often, it is not even necessary for an alternative therapist to completely invent a diagnosis. Patients usually consult an alternative practitioner with some sort of symptom – frequently with what one might call a medical triviality that does not need any treatment at all but can be dealt with differently, for instance, by issuing some life-style advice or just simple re-assurance that nothing major is amiss. But for the fear-monger, this is not enough. He feels the need to administer his therapy, and for that purpose he needs to medicalize trivialities :

  • A low mood thus becomes a clinical depression.
  • A sore back is turned into a nasty lumbago.
  • A tummy upset morphs into a dangerous gastritis.
  • Abdominal unrest is diagnosed to be a leaky gut syndrome.
  • A food aversion turns into a food intolerance, etc., etc.

The common denominator is again the fact that fear is instilled into the patient. And again, a useless therapy is administered, if at all possible in the form of a lengthy series of treatments. This, of course, generates significant benefit – not therapeutic, but financial!


But there is always the risk that the patient is wiser than expected. She might be so scared learning of her condition that she decides to see her doctor. That would mean a loss of income which has to be avoided! The trick to achieve this is usually not difficult: conventional healthcare professionals must be demonized.

  • They are not treating the root cause of the problem.
  • They are in the pocket of BIG PHARMA.
  • They prescribe medicines with terrible side-effects.
  • They have no idea about holism.
  • They never have enough time to listen, etc., etc.

I know, some of these criticisms are not entirely incorrect (for instance, many conventional medicines do have serious side-effects but, as I try to point out ad nauseam, we need to consider their risk/benefit balance). But that is hardly the point here; the point is to scare the patient off conventional medicine. Only a person who is convinced that the ‘medical mafia’ is out to get her, will prove to be a loyal customer of all things alternative.


And a loyal customer is someone who comes not just once or twice but regularly, ideally from cradle to grave. The way to achieve this ultimate stimulus of the practitioners cash flow is to convince the patient that she needs regular treatments, even when she feels perfectly alright. The magic word here is PREVENTION! The masters here are the chiropractors, I guess; they promote what they call ‘maintenance care’, i.e. the regular treatment of healthy individuals to keep their spines subluxation-free. It goes without saying that maintenance care is a money-making scam.

The strategy requires two little lies, but that’s forgivable considering the good cause, boosting the income of the practitioner:

  1. Conventional doctors don’t do prevention.
  2. The alternative treatment is an effective preventative.

The first statement can be shown to be an obvious lie. All we know about effective disease prevention today comes from conventional medicine and science; nothing originates from the realm of alternative medicine. Remarkably, the most efficacious preventative measure of all times, immunisation, is frequently defamed and neglected by alternative practitioners.

The second statement is a necessary lie; how else would a patient agree to pay regularly for the practitioner’s services? I am not aware of any alternative therapy that can effectively prevent any disease.


  • Some alternative practitioners regularly instil fear into consumers.
  • Several strategies are being used for this purpose.
  • They have the aim of maximising the therapists’ income.
  • Fear-mongering is unethical and despicable.
  • Pointing out that a certain therapy might fail to generate more good than harm is not fear-mongering.

Olivia Newton-John is postponing her June U.S. and Canadian concert tour dates, as the back pain that initially caused her to postpone the first half of her concert tour, has been diagnosed as bone metastases  form her earlier breast cancer. She now intends to complete a short course of photon radiation therapy along with alternative therapies for improving her quality of life. “I decided on my direction of therapies after consultation with my doctors and natural therapists and the medical team at my Olivia Newton-John Cancer Wellness and Research Centre in Melbourne”,  Newton-John said. The actress had been diagnosed with breast cancer in 1992. At that time, she underwent chemotherapy after initially trying alternative treatments like acupuncture and homeopathy.

Olivia Newton-John’s daughter Chloe Lattanzi has said her mum would use cannabis oil to aid in her fight against cancer, while long-time friend John Farnham has thrown his support behind the singer. Lattanzi owns a legal marijuana farm in Oregon and said that her mum would also use other natural healing remedies plus modern medicine in addition to cannabis oil to help her battle the deadly disease for the second time.

The Olivia Newton-John Cancer Wellness & Research Centre is a treatment centre of Austin Health, an Australian public hospital. They say that “anyone with a referral from their doctor can be treated here, regardless of the stage of their treatment or insurance status. At the ONJ Centre your care is built around your individual needs. This includes your physical, psychological and emotional health. Every patient is surrounded by a multidisciplinary team of cancer specialists, allied health and wellbeing therapists. Your dedicated treatment team work together to guide you through your optimal treatment pathway. Learn more about the cancer treatments we deliver at the ONJ Centre, how we support you through your care, and find answers to commonly asked questions.”

Their therapies include acupuncture and several other alternatives used for palliation, but the site seems refreshingly free of false claims and quackery. On their website, they say that “palliative care assists patients who have a life limiting illness to be as symptom free as possible. We work with you to meet your emotional, spiritual and practical needs in a holistic way. Our support is also extended to your family and carers.”

Altogether, this seems like a fairly reasonable approach. Olivia might have learnt a lesson the hard way when her initial breast cancer did not respond to homeopathy. Let’s hope she does get her metastases under control with cutting edge cancer care and is able to keep her spirits up with the additional help of a little complementary medicine.

The new guidelines by the American College of Physicians entitled ‘Noninvasive Treatments for Acute, Subacute, and Chronic Low Back Pain: A Clinical Practice Guideline From the American College of Physicians’ have already been the subject of the previous post. Today, I want to have a closer look at a small section of these guidelines which, I think, is crucial. It is entitled ‘HARMS OF NONPHARMACOLOGIC THERAPIES’. I have taken the liberty of copying it below:

“Evidence on adverse events from the included RCTs and systematic reviews was limited, and the quality of evidence for all available harms data is low. Harms were poorly reported (if they were reported at all) for most of the interventions.

Low-quality evidence showed no reported harms or serious adverse events associated with tai chi, psychological interventions, multidisciplinary rehabilitation, ultrasound, acupuncture, lumbar support, or traction (9,95,150,170–174). Low-quality evidence showed that when harms were reported for exercise, they were often related to muscle soreness and increased pain, and no serious harms were reported. All reported harms associated with yoga were mild to moderate (119). Low-quality evidence showed that none of the RCTs reported any serious adverse events with massage, although 2 RCTs reported soreness during or after massage therapy (175,176). Adverse events associated with spinal manipulation included muscle soreness or transient increases in pain (134). There were few adverse events reported and no clear differences between MCE and controls. Transcutaneous electrical nerve stimulation was associated with an increased risk for skin site reaction but not serious adverse events (177). Two RCTs (178,179) showed an increased risk for skin flushing with heat compared with no heat or placebo, and no serious adverse events were reported. There were no data on cold therapy. Evidence was insufficient to determine harms of electrical muscle stimulation, LLLT, percutaneous electrical nerve stimulation, interferential therapy, short-wave diathermy, and taping.”

The first thing that strikes me is the brevity of the section. Surely, guidelines of this nature must include a full discussion of the risks of the treatments in question!

The second thing that is noteworthy is the fact that the authors confirm the fact I have been banging on about for years: clinical trials of alternative therapies far too often fail to mention adverse effects.  I have often pointed out that the failure to report adverse effects in clinical trials is an unacceptable violation of medical ethics. By contrast, the guideline authors seem not to feel strongly about this omission.

The third thing that is noteworthy is that the guidelines evaluate the harms of the treatments purely on the basis of the adverse effects reported in the clinical trials and systematic reviews included in their efficacy assessments. This is nonsensical for at least two reasons:

  1. The guideline authors themselves are aware that the trials very often fail to mention adverse effects.
  2. For any assessment of harm, one has to go far beyond the evidence of clinical trials, because trials tend to be too small to pick up rare adverse effects, and because they are always conducted under optimally controlled conditions where adverse effects are less likely to occur than in real life.

Together, these features of the assessment of harms explain why the guideline authors arrive at conclusions which are oddly misguided; I would even feel that they resemble a white-wash. Here are two of the most overt misjudgements:

  • no harms associated with acupuncture,
  • only trivial harm associated with spinal manipulations.

The best evidence we have today shows that acupuncture leads to mild adverse effects in about 10% of all cases and is also associated with very severe complications (e.g. pneumothorax, cardiac tamponade, infections, deaths) in an unknown number of patients. More details can be found for instance here, here, here and here.

And the best evidence available shows that spinal manipulation leads to moderately severe adverse effects in ~50% of all cases. In addition, we know of hundreds of cases of very severe complications resulting in stroke, permanent neurological deficits or deaths. More details can be found for instance here, here, here and here.

In the introduction, I stated that this small section of the guidelines is crucial.


The reason is simple: any responsible therapeutic decision has to be based not just on the efficacy of the treatment in question but on its risk/benefit balance. The evidence shows that the risks of some alternative therapies can be considerable, a fact that is almost totally neglected in the guidelines. Therefore, the recommendations of the new guidelines by the American College of Physicians entitled ‘Noninvasive Treatments for Acute, Subacute, and Chronic Low Back Pain: A Clinical Practice Guideline From the American College of Physicians’ are in several aspects not entirely correct and need to be reconsidered.

Concerned about the new ACP guidelines on ‘Noninvasive Treatments for Acute, Subacute, and Chronic Low Back Pain: A Clinical Practice Guideline From the American College of Physicians’, Andrea MacGregor asked me to publish her ‘open letter’:

I am a student about to graduate and register as a massage therapist in Canada, and I am writing to express my concern with your recommendation of the use of acupuncture in your new guideline for low-back pain management.

Leading medical and health research experts from around the world, including many who are highly familiar with the use of complementary and alternative therapies, have contributed to a highly informed commentary (attached) assembled by the Friends of Science in Medicine association (Aus.), which supports a strong conclusion that acupuncture is not effective for any specific condition, and that the evidence for it being an effective intervention for low-back pain is not convincing. Another review of acupuncture by FSM concluding that there is a lack of evidence of a therapeutic effect has been endorsed by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. Respected American medical science writers also maintain that claims of acupuncture’s efficacy are not science-based (examples here and here).

Additionally, previous acupuncture recommendations are being reconsidered by prominent institutions in other parts of the world. The National Institute for Health and Care Excellence guideline for NHS patients in the United Kingdom now recommends against the use of acupuncture for low-back pain, following a high-quality review that critically examined the existing evidence regarding the use of acupuncture and found it to be no more effective than a placebo. The Toronto Hospital for Sick Children has also recently removed references on their website that suggested the efficacy of acupuncture in managing specific chronic pain conditions. The World Health Organization has done the same, no longer suggesting that acupuncture is effective for low-back pain and sciatica.

As someone about to enter a field that is frequently associated with, or considered a part of, complementary healthcare, I know how tempting it can be for us, as professionals and as researchers, to exaggerate claims of efficacy and pin some very high hopes on “new possibilities” in physical therapies.

I also know first-hand how misguided and overblown some of these claims and hopes can be. Many of my own peers and instructors are proponents of acupuncture, and it is common for Canadian massage therapists to become licensed acupuncturists (a similar connection between massage and acupuncture communities, of course, also exists in the United States). I have often seen my own mentors and comrades pushing for the use of acupuncture treatments for many chronic and serious conditions for which there is no basis of evidence at all of acupuncture’s efficacy, including systemic, neurological, and developmental conditions. When questioned, they will usually refer to authorities perceived as “legitimate”, including the American College of Physicians, to say that claims of acupuncture “working” are backed by experts— whether their claims are even pain-related or not.

We see a similar situation with advertisers and media using the guise of “expert-backed” legitimization to recommend acupuncture in misleading ways, often to vulnerable people who could be making better-informed and more effective treatment and management choices for their conditions. Many of these advertising and media entities specifically mention the American College of Physicians as lending credence to their claims, sometimes somewhat out of context.

As someone with a chronic neurological disorder, I find it troubling to see untrue or exaggerated claims of benefit for incurable or serious conditions when we could be focusing on more accurate ideas and having more honest, realistic discussions of our options. This is also important when it comes to deciding how to best allocate our limited health funding resources. Quite a lot of our insurance and out-of-pocket funds are spent on alternative therapies, and it’s important to see things going to use in a way that’s proportionate and appropriate to the evidence we have.

I hope that you will reconsider your recommendation of a practice that is simply not supported by the majority of the research evidence that exists to date. Patients with complex conditions, including low-back pain, deserve accurate and realistic information regarding their treatment options, especially from such trusted and reputable sources as the American College of Physicians. Thank you for your time and attention.

According to Sir Richard: “From everything I have read about acupuncture I have to conclude that the evidence for efficacy is just not there.  I can believe it has a very strong and effective placebo effect, but if it really worked as advertised why are the numbers of successful outcomes so small when compared to treatments such as drugs that really do work. As a scientist, who likes to see proper experiments carried out so that the results can be judged with a rational analysis, the experiments I have read about just don’t meet even a low bar of acceptability. I certainly do not believe it should be endorsed as an effective treatment by any professional scientific or medical body that values its reputation.”

According to Professor Bogduk: “Although studies have shown that acupuncture “works”, the definition of “works” is generous. Most studies show minimal to no effect greater than that of sham therapy. Needles do not need to be placed at specific points; so, learning about meridians is not required. Effectiveness is marginally greater in those patients who believe in acupuncture or expect it to work. However, no studies have shown that acupuncture stops pain, while also restoring normal function and removing the need for other health care.”

According to Professor Caulfield: “In popular culture, acupuncture is often portrayed as being effective for a range of conditions. It is held up as an alternative medicine success story. In fact, the relevant data are, at best, equivocal. The most rigorous studies, such as those that are well controlled and use sham comparators, have found that in most situations acupuncture is little better than placebo.  More importantly, the supernatural foundations of the practice – that illness can be attributed to an imbalance in a life force energy – has absolutely no scientific basis. Given this reality, public representations of acupuncture that present it as science-based and effective can be deeply misleading.  Policies are needed to counter this noise, including, inter alia, the more aggressive deployment of truth-in-advertising regulations, the enforcement of a conceptually consistent science-based informed consent standard, and the oversight of healthcare professionals by the relevant regulatory entities.”

According to Professor Kanellopoulos: “According to the systematic reviews in the field of acupuncture, the benefits of the method, if any, are nothing more than a temporary placebo effect. From a scientific point of view, acupuncture is based on a theory, which has nothing to do with modern physiology and medicine. From a researcher’s point of view, any presented acupuncture effectiveness is due to methodological errors, data manipulation, statistical artefacts and (purposely?) poorly designed clinical trials in general. Finally, regarding the patient, any symptom’s relief comes from despair and post hoc fallacy. After decades of research and over 3000 clinical trials, any continuation of practicing, advertising, and research in the field of acupuncture is a waste of resources and puts the patients at risk, raising ethical issues for both science and society.”

According to Professor Campbell: “Acupuncture holds great theatrical appeal through its dramatic and historical aspects, particularly to those who feel that conventional medicine has failed to offer pain relief or sufficient improvement in symptoms. However an extensive body of data now exists from rigorous approaches to testing the validity of its claims of benefit actually related to the placement of the needles and not to placebo effect. For example, most recently the beneficial effect achieved in relieving fatigue in Parkinsons Disease (and there was one) was identical in a randomised controlled trial to that of placebo.”

According to Professor Donald M. Marcus: “When trials of acupuncture for relief of pain of osteoarthritis of the knee or back pain include a sham acupuncture control, there is no clinically relevant difference in efficacy between the conventional and sham procedures. A number of sham procedures have been used, including toothpicks in a plastic guide tube in a study of back pain. It’s evident that relief of pain, and probably other complaints, by acupuncture is mediated by a placebo mechanism. Since there is no scientific evidence supporting its efficacy, medical insurance should not pay for acupuncture treatments. Moreover, it is unethical to deceive patients by providing a placebo treatment without disclosure.”

According to pain specialist Dr Vagg: “Due to the lack of a scientifically plausible mechanism, and the poor quality of the bulk of the research concerning acupuncture in its many and varied forms, no credible body of pain medicine researchers or clinicians has endorsed any type of acupuncture as a recommended treatment for any identifiable group of patients with persistent pain. Moreover, there is no reason to suppose that further research of high quality will change this conclusion, given that high-quality, randomized and double-blinded studies have uniformly shown that any form of acupuncture is indistinguishable from placebo, making further research unwarranted.”

According to Professor Garrett: “Current levels of evidence on acupuncture as a therapeutic intervention for any condition is very poor. Most studies reported  are of very poor quality and are not reliable. Unfortunately, there is a strong element of propaganda in the dissemination of support for acupuncture in China, as it is a part of the Traditional Chinese Medicine supported by the government there. As such, much research has been demonstrated to involve data fabrication and extreme levels of confirmation bias. There are also strong ethical concerns about research involving acupuncture in China for anesthesia or other conditions where there is no established clinical theoretical basis for its use, and far better established therapeutics are available. Overall the current state of evidence on acupuncture is that the effectiveness of acupuncture as a treatment of any health condition remains unproven, and the only good quality trials have identified it has no better outcomes than placebo. Therefore, any claims of efficacy made against specific medical conditions are deceptive.”

According to Professor Gorski: “Acupuncture seems to garner more belief because it seems more plausible. The reason is that, unlike many other alternative therapies, acupuncture actually involves a physical act, namely inserting needles into the skin. However, it is also the case that the more acupuncture has been studied, the more it has become clear that it is, as David Colquhoun and Steve Novella put it, nothing more than a theatrical placebo. Indeed, as acupuncture is more rigorously studied in randomized clinical trials with proper controls and proper blinding, the more its seeming effects disappear, so that it becomes indistinguishable from placebo. Nor is it without risk, either. Recommending acupuncture to treat any condition is, from an ethical and scientific view, indefensible.”

According to Professor Bartecchi: “Acupuncture has no medical value other than that of a placebo. Acupuncture as viewed by many of us in academic medicine is merely an elaborate, theatrical placebo, a pre-scientific superstition which lacks a plausible mechanism. It really fits the bill as an alternative medicine hoax.”

According to Professor Colquhoun: “After over 3000 trials, some of them very well designed, there is still argument about the effectiveness of acupuncture.  If that were the case for a new drug, it would long since have been abandoned. The literature suggests that acupuncture has only a small and variable placebo effect: too small to be of noticeable benefit to patients. Most of its apparent effects result from a statistical artefact, regression to the mean. The continued use of acupuncture probably arises from the lack of effective treatments for conditions like non-specific low back pain. That cannot be justified, Neither is it worth spending yet more money on further research. The research has been done and it failed to produce convincing evidence.”

According to Professor Ernst: “The current evidence on acupuncture is mixed. Many trials are less than rigorous and thus not reliable. Much of the research comes from China where data fabrication has been disclosed to be at epidemic levels; it would therefore be a mistake to rely on studies from China which almost invariably report positive results.  If we account for such caveats and critically review the literature, we arrive at the following conclusions: – Acupuncture is clearly not free of risks, some of which are serious;  – The effectiveness of acupuncture as a treatment of any condition remains unproven, and – The current research in this area is mostly pseudo-research aimed at promoting rather than testing acupuncture”.

According to Professor Costa: “Acupuncture as a part of Traditional Chinese Medicine is not based on science simply because, as for all pre-scientific medicines, whether Greco-Roman-European, Indian or any other, none are founded on any evidence. As a Neuroscientist, I teach medical and non medical students the very foundations of how the nervous system works and how sensory stimulation affects the brain. There simply is no evidence that twigging the skin with needles or, for that matter with toothpicks, does any more than create an expectation to feel better. This is the well-known placebo effect. Selling placebos under the disguise of medicine is totally unethical.”

According to Professor MacLennan: “Acupuncture is elaborate quackery and like many placebos sold by those without responsibility for or knowledge of the wide range of health disorders and disease it can be dangerous. Dangerous because acupuncture may delay correct diagnosis and therapy, dangerous because it may delay possible evidence-based therapies and allow progression of disorders present and dangerous because it sucks limited health resources from the community.   Acupuncturists derive their income from elaborate subterfuge, taking advantage of the gullible unwell who are desperate, uneducated and seek a magic cure. If there is a placebo effect it is usually temporary, and eventually disappointment from lack of long term effect may lead to secondary depression in the patient.    According to Professor Dwyer: “Modern understanding of human anatomy and the distribution and function of the components of the human nervous system make a nonsense of theories that suggest there are invisible meridians criss-crossing the body wherein there are trigger spots which, when stimulated, can produce an array of benefits remote from that site. Scientists however, while dismissing the prescientific explanations offered by traditional Chinese medicine, have sought other reasons why acupuncture might provide clinical benefits particularly the relief of pain. Numerous theories have been addressed by numerous studies with many being conducted using disciplined scientific methods. The conclusions leave us with no doubt that acupuncture provides the scenario for a superb theatrical placebo; no more.”

According to Dr Novella:  “Pain is a big problem. If you read about pain management centers, you might think it had been solved. It has not. And when no effective treatment exists for a medical problem, it leads to a tendency to clutch at straws. Research has shown that acupuncture is little more than such a straw. It is clear from meta-analyses that results of acupuncture trials are variable and inconsistent, even for single conditions. After thousands of trials of acupuncture and hundreds of systematic reviews, arguments continue unabated. In 2011, Pain published an editorial that summed up the present situation well.”

According to Professor London & Dr Barrett: “The optimistic article by Vickers et al did not consider an important point. Research studies may not reflect what takes place in most acupuncturist offices. Most acupuncturists are graduates of “oriental medical schools,” where they learn about 5element theory, “energy” flow through meridians, and other fanciful traditional Chinese medicine (TCM) concepts that do not correspond with scientific knowledge of anatomy, physiology, or pathology. Practitioners of TCM typically rely on inappropriate diagnostic procedures (pulse and tongue diagnosis) and prescribe herbal mixtures that have not been sufficiently studied. Diagnoses based on TCM such as “Qi stagnation,” “blood stagnation,” “kidney Qi deficiency,” and “yin deficiency” may not jeopardize patients who are treated in an academic setting, where they have received a medical diagnosed before entering the study. But what about people with conditions that TCM-trained acupuncturists are not qualified or inclined to diagnose? Real-world evaluations of acupuncture should also consider the cost of unnecessary treatment.”

According to Professor Salzberg: “Acupuncture is a pre-scientific practice that persists only because of relentless and often very clever marketing by its proponents. The claimed mechanisms by which acupuncture works are clearly and obviously false: modern physiology, neurology, cell biology, and other scientific disciplines explain how pain signals are transmitted in the body, and none of them support the supposed “qi” or energy fields flowing along “meridians,” as acupuncturists describe them. Hundreds of scientific studies have shown that acupuncture doesn’t work for any medical condition. Acupuncture proponents ignore the evidence and persist, primarily because they profit from their practices. There are also documented risks of complications from acupuncture, ranging from infections to punctured lungs. For these and other reasons, recommending acupuncture for any patient is simply unethical. Acupuncturists make profits by putting patients at risk.”

According to Professor French: “Acupuncture has been extensively evaluated with respect to its possible therapeutic effectiveness for a wide range of disorders. The overall conclusion from meta-analyses of such studies is that any beneficial effects reported are small in terms of effect size and probably best accounted for in terms of statistical artefacts and placebo effects, etc. In general, the higher the quality of the study, the less likely are any beneficial effects to be reported. In light of this, it would be unwise and unethical to recommend acupuncture as the treatment of choice for any condition.”

According to Dr Renckens: “In 1683 the Dutch physician Willem ten Rhijne published the first book in the western world in which the word ‘acupuncture’ was mentioned, which referred to – as the Dutch title of the book was – ‘The Chinese and Japanese way of curing all diseases and especially the podagra by burning moxa and stabbing the Golden Needle’. This exotic treatment did not gain any popularity in the Netherlands and was mainly ridiculed. This heavenly situation remained unchanged until Nixon’s trip to China (1972) and the ‘successful’ acupuncture-treatment of the journalist James Reston of the New York Times. His story in that influential newspaper caused worldwide interest in acupunctures possible benefits. Also in the Netherlands and as early as 1989 a series of systematic reviews on the efficacy of acupuncture in a number of diseases was published in the Huisarts & Wetenschap, a journal of GP’s in the Dutch language (Ter Riet et al. H&W,1989;32:308-312).Their final conclusion was: ‘the main achievement of Chinese acupuncture is to have discovered a number of spots on the human body into which needles can be safely inserted’. The huge amount of scientific research into acupuncture has since been unable to undermine this right conclusion.”
According to Dr Braillon: “No discrimination!  The US Federal Trade Commission announced that homeopathic drugs should “be held to the same truthin-advertising standards as other products claiming health benefits”; very soon, homeopathic products will include statements indicating: “There is no scientific evidence backing homeopathic health claims” and “Homeopathic claims are based only on theories from the 1700s that are not accepted by modern medical experts.”  In Australia, the Royal Australian College of General Practitioners formally recommended GPs to ban homeopathic products from their prescriptions and pharmacists to ban them from their shelves. The same should be required for acupuncture.”

According to Dr McLennon: “Despite claims for effectiveness, there have been very few studies of acupuncture on children that have confirmed significant benefits.  Conditions such as headache, abdominal pain, bed wetting and fibromyalgia and behaviour problems such as ADHD have been investigated. More trials with better structure have universally been recommended. A double blinded trial on the treatment of headaches with laser acupuncture illustrates the problems. The number of patients was quite small (21 in each arm), the diagnoses were reasonable medically but required rediagnosis to fit Traditional Chinese Medicine criteria and treatments were individualised based on these diagnoses. It was not made clear whether the patients were completely blinded i.e. unaware they received active treatment or placebo. Until blinding can be guaranteed, trials of acupuncture will remain inconclusive.”
According to Professor Holt: “Unlike some alternative therapies, acupuncture has been extensively studied for many medical conditions and a summary would be that the higher the quality of the study, the less likely it is that a benefit other than a placebo effect is found. Studies have shown conclusively that a key aspect of acupuncture, putting needles into energy lines for medical benefits, is not true, and the same effect is elicited wherever the needles are placed. Acupuncture is not a science-based practice, can cause side effects and is not recommended for any medical condition.”

According to Dr Oppel: “It is extremely concerning that there remains no plausible rationale for a mechanism of action of acupuncture.  It is noteworthy that different schools of acupuncture offer contradictory patterns of treatment. It should not go without notice that acupuncture has been so well-researched that there are hundreds , if not thousands, of clinical trials now available Unfortunately, although there is no compelling evidence of effectiveness for any of the myriad of conditions where  acupuncture is claimed to be of benefit, poor quality unreplicated trials continue to be put forward by proponents as proof of acupuncture’s effectiveness. Critical thinkers will also take note that while the large majority of acupuncture trials are positive, the vast majority of properly controlled trials are not.   We are in a situation now where we have excellent evidence that acupuncture is not effective.”

According to Professor Hróbjartsson: “While there have been many trials done with acupuncture, most of them are small pilot studies and large scale high quality trials are rare. Some studies have reported measurable effects, but the mechanism is not yet understood, the size of the effect is small and it is possible that a large part of the effect or all of the effect is placebo. It is obvious that you would see a physiological effect when you stick a needle into your body, the question is whether that has a measurable clinical effect. There is insufficient evidence to say that electro acupuncture is any more or any less effective.”

According to Professor Pandolfi: “With a rationale completely disconnected from the basic principles of science acupuncture cannot be considered as belonging to modern evidence–based medicine.”

According to Professor Baker: “Millions of people are affected every year by these often debilitating and distressing conditions. For most their symptoms improve in days or weeks. However for some, the pain can be distressing and persist for a long time. Regrettably there is a lack of convincing evidence of effectiveness for some widely used treatments. For example acupuncture is no longer recommended for managing low back pain with or without sciatica. This is because there is not enough evidence to show that it is more effective than sham treatment.”

The BMJ has always been my favourite Medical journal. (Need any proof for this statement? A quick Medline search tells me that I have over 60 publications in the BMJ.) But occasionally, the BMJ also disappoints me a great deal.

One of the most significant disappointments was recently published under the heading of STATE OF THE ART REVIEW. A review that is ‘state of the art’ must fulfil certain criteria; foremost it should be informative, unbiased and correct. The paper I am discussing here has, I think, neither of these qualities. It is entitled ‘Management of chronic pain using complementary and integrative medicine’, and here is its abstract:

Complementary and integrative medicine (CIM) encompasses both Western-style medicine and complementary health approaches as a new combined approach to treat a variety of clinical conditions. Chronic pain is the leading indication for use of CIM, and about 33% of adults and 12% of children in the US have used it in this context. Although advances have been made in treatments for chronic pain, it remains inadequately controlled for many people. Adverse effects and complications of analgesic drugs, such as addiction, kidney failure, and gastrointestinal bleeding, also limit their use. CIM offers a multimodality treatment approach that can tackle the multidimensional nature of pain with fewer or no serious adverse effects. This review focuses on the use of CIM in three conditions with a high incidence of chronic pain: back pain, neck pain, and rheumatoid arthritis. It summarizes research on the mechanisms of action and clinical studies on the efficacy of commonly used CIM modalities such as acupuncture, mind-body system, dietary interventions and fasting, and herbal medicine and nutrients.

The full text of this article is such that I could take issue with almost every second statement in it. Obviously, this would be too long and too boring for this blog. So, to keep it crisp and entertaining, let me copy the (tongue in cheek) ‘letter to the editor’ some of us published in the BMJ as a response to the review:

“Alternative facts are fashionable in politics these days, so why not also in healthcare? The article by Chen and Michalsen on provides a handy set of five instructions for smuggling alternative facts into medicine.

1. Create your own terminology: the term ‘complementary and integrated medicine’ (CIM) is nonsensical. Integrated medicine (a hotly disputed field) already covers complementary and conventional medicine.

2. Pretend to be objective: Chen and Michalsen elaborate on the systematic searches they conducted. But they omit hundreds of sources which do not support their message, which cherry-picks only evidence for the efficacy of the treatments they promote.

3. Avoid negativity: they bypass any material that might challenge what they include. For instance, when discussing therapeutic risks, they omit the disturbing lack of post-marketing surveillance: the reason we lack information on adverse events. They even omit to mention the many fatalities caused by their ‘CIM’.

4. Create an impression of thoroughness: Chen and Michalsen cite a total of 225 references. This apparent scholarly attention to detail masks their misuse of many of they list. Reference 82, for example, is employed to back up the claim that “satisfaction was lowest among complementary medicine users with rheumatoid arthritis, vasculitis, or connective tissue diseases”. In fact, it shows nothing of the sort.

5. Back up your message with broad generalisations: Chen and Michalsen conclude that “Taken together, CIM has an increasing role in the management of chronic pain, but high quality research is needed”. The implication is that all the CIMs mentioned in their figure 1 are candidates for pain control – even discredited treatments such as homeopathy.

In our view, these authors render us a service: they demonstrate to the novice how alternative facts may be used in medicine.”

I am sure you have your own comments and opinions, and I encourage you to post them here or (better) submit them to the BMJ or (best) both.

The aim of this pragmatic study was “to investigate the effectiveness of acupuncture in addition to routine care in patients with allergic asthma compared to treatment with routine care alone.”

Patients with allergic asthma were included in a controlled trial and randomized to receive up to 15 acupuncture sessions over 3 months plus routine care, or to a control group receiving routine care alone. Patients who did not consent to randomization received acupuncture treatment for the first 3 months and were followed as a cohort. All trial patients were allowed to receive routine care in addition to study treatment. The primary endpoint was the asthma quality of life questionnaire (AQLQ, range: 1–7) at 3 months. Secondary endpoints included general health related to quality of life (Short-Form-36, SF-36, range 0–100). Outcome parameters were assessed at baseline and at 3 and 6 months.

A total of 1,445 patients were randomized and included in the analysis (184 patients randomized to acupuncture plus routine care and 173 to routine care alone, and 1,088 in the nonrandomized acupuncture plus routine care group). In the randomized part, acupuncture was associated with an improvement in the AQLQ score compared to the control group (difference acupuncture vs. control group 0.7 [95% confidence interval (CI) 0.5–1.0]) as well as in the physical component scale and the mental component scale of the SF-36 (physical: 2.5 [1.0–4.0]; mental 4.0 [2.1–6.0]) after 3 months. Treatment success was maintained throughout 6 months. Patients not consenting to randomization showed similar improvements as the randomized acupuncture group.

The authors concluded that in patients with allergic asthma, additional acupuncture treatment to routine care was associated with increased disease-specific and health-related quality of life compared to treatment with routine care alone.

We have been over this so many times (see for instance here, here and here) that I am almost a little embarrassed to explain it again: it is fairly easy to design an RCT such that it can only produce a positive result. The currently most popular way to achieve this aim in alternative medicine research is to do a ‘A+B versus B’ study, where A = the experimental treatment, and B = routine care. As A always amounts to more than nothing – in the above trial acupuncture would have placebo effects and the extra attention would also amount to something – A+B must always be more than B alone. The easiest way of thinking of this is to imagine that A and B are both finite amounts of money; everyone can understand that A+B must always be more than B!

Why then do acupuncture researchers not get the point? Are they that stupid? I happen to know some of the authors of the above paper personally, and I can assure you, they are not stupid!

So, why?

I am afraid there is only one reason I can think of: they know perfectly well that such an RCT can only produce a positive finding, and precisely that is their reason for conducting such a study. In other words, they are not using science to test a hypothesis, they deliberately abuse it to promote their pet therapy or hypothesis.

As I stated above, it is fairly easy to design an RCT such that it can only produce a positive result. Yet, it is arguably also unethical, perhaps even fraudulent, to do this. In my view, such RCTs amount to pseudoscience and scientific misconduct.

Acupuncture is little more than a theatrical placebo! If we confront an acupuncture fan with this statement, he/she is bound to argue that there are some indications for which the evidence is soundly positive. One of these conditions, they would claim, is nausea and vomiting. But how strong are these data? A new study sheds some light on this question.

The objective of this RCT was to evaluate if consumption of antiemetics and eating capacity differed between patients receiving verum acupuncture, sham acupuncture, or standard care only during radiotherapy. Patients were randomized to verum (n = 100) or sham (n = 100) acupuncture (telescopic blunt sham needle) (12 sessions) and registered daily their consumption of antiemetics and eating capacity. A standard care group (n = 62) received standard care only.

The results show that more patients in the verum and the sham acupuncture group did not need any antiemetic medications, as compared to the standard care group after receiving 27 Gray dose of radiotherapy. More patients in the verum and the sham acupuncture group were capable of eating as usual, compared to the standard care group. Patients receiving acupuncture had lower consumption of antiemetics and better eating capacity than patients receiving standard antiemetic care, plausible by nonspecific effects of the extra care during acupuncture.

The authors concluded that patients receiving acupuncture had lower consumption of antiemetics and better eating capacity than patients receiving standard antiemetic care, plausible by nonspecific effects of the extra care during acupuncture.

I find these conclusions odd because they seem to state that acupuncture was more effective than standard care. Subsequently – almost as an afterthought – they mention that its effects are brought about by nonspecific effects. This is grossly misleading, in my view.

The study was designed as a comparison between real and sham acupuncture, and the standard care group was not a randomised comparison group. Therefore, the main result and conclusion has to focus on the comparison between verum and sham acupuncture. This comparison shows that the two did not produce different result. Therefore, the study shows that acupuncture was not effective.


Drug and alcohol dependencies are notoriously difficult to treat effectively. Patients and their families are often desperate and willing to try anything. This seems like an ideal ground for acupuncturists who are, in my experience, experts in putting up smokescreens hiding the true value of their treatment.

The best way to determine the value of any intervention is probably conducting a systematic review of the evidence from rigorous clinical trials. Today we are in the fortunate position to have not just one of those articles; but do they really tell us the truth?

This brand-new systematic review investigated the effects of acupuncture on alcohol-related symptoms and behaviors in patients with this disorder. The PubMed database was searched until 23 August 2016, and reference lists from review studies were also reviewed. The inclusion criteria were the following: (1) being published in a peer-reviewed English-language journal, (2) use of randomized controlled trials (RCTs), (3) assessing the effects of acupuncture on psychological variables in individuals with a primary alcohol problem, and (4) reporting statistics that could be converted to effect sizes.

Seventeen studies were identified for a full-text inspection, and seven (243 patients) of these met our inclusion criteria. The outcomes assessed at the last post-treatment point and any available follow-up data were extracted from each of the studies. Five studies treated patients by inserting a needle into several acupoints in each ear. Two studies stimulated body points with or without ear stimulation. Four studies treated control patients with a placebo needle or under a completely different type of intervention, such as relaxation or transdermal stimulation, whereas the remaining studies inserted needles into nonspecific points. The patients were treated for 2 weeks to 3 months, and the treatment duration per session was 15–45 min. The results of the meta-analysis demonstrated that an acupuncture intervention had a stronger effect on reducing alcohol-related symptoms and behaviours than did the control intervention. A beneficial but weak effect of acupuncture treatment was also found in the follow-up data.

The authors concluded that although our analysis showed a significant difference between acupuncture and the control intervention in patients with alcohol use disorder, this meta-analysis is limited by the small number of studies included. Thus, a larger cohort study is required to provide a firm conclusion.

I am used to reading poor research papers, but this one is like a new dimension. Here are just the most obvious flaws:

  • by searching just one database, the likelihood of missing studies is huge,
  • by excluding non-English papers, the review automatically becomes non-systematic,
  • the included studies differed vastly in many respects and can therefore not be pooled.

As it happens, a further meta-analysis has just been published. Here is its abstract:

Acupuncture has been widely used as a treatment for alcohol dependence. An updated and rigorously conducted systematic review is needed to establish the extent and quality of the evidence on the effectiveness of acupuncture as an intervention for reducing alcohol dependence. This review aimed to ascertain the effectiveness of acupuncture for reducing alcohol dependence as assessed by changes in either craving or withdrawal symptoms.


In this systematic review, a search strategy was designed to identify randomised controlled trials (RCTs) published in either the English or Chinese literature, with a priori eligibility criteria. The following English language databases were searched from inception until June 2015: AMED, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and PubMed; and the following Chinese language databases were similarly searched: CNKI, Sino-med, VIP, and WanFang. Methodological quality of identified RCTs was assessed using the Jadad Scale and the Cochrane Risk of Bias tool.


Fifteen RCTs were included in this review, comprising 1378 participants. The majority of the RCTs were rated as having poor methodological rigour. A statistically significant effect was found in the two primary analyses: acupuncture reduced alcohol craving compared with all controls (SMD = −1.24, 95% CI = −1.96 to −0.51); and acupuncture reduced alcohol withdrawal symptoms compared with all controls (SMD = −0.50, 95% CI = −0.83 to −0.17). In secondary analyses: acupuncture reduced craving compared with sham acupuncture (SMD = −1.00, 95% CI = −1.79 to −0.21); acupuncture reduced craving compared with controls in RCTs conducted in Western countries (SMD = −1.15, 95% CI = −2.12 to −0.18); and acupuncture reduced craving compared with controls in RCTs with only male participants (SMD = −1.68, 95% CI = −2.62 to −0.75).


This study showed that acupuncture was potentially effective in reducing alcohol craving and withdrawal symptoms and could be considered as an additional treatment choice and/or referral option within national healthcare systems.

This Meta-analysis is only a little better than the first, I am afraid. What its conclusions do not sufficiently reflect, in my view, is the fact that the quality of the primary studies was mostly very poor – too poor to draw conclusions from (other than ‘acupuncture research is usually lousy’; see figure below). Therefore, I fail to see how the authors could draw the relatively firm and positive conclusions cited above. In my view, they should have stated something like this: DUE TO THE RISK OF BIAS IN MANY TRIALS, THE EFFECTIVENESS OF ACUPUNCTURE REMAINS UNPROVEN.

The authors of the first meta-analysis open the discussion by proudly declaring that “the present study is the first meta-analysis to examine the effect of acupuncture treatment on patients with alcohol use disorder and to provide data on the magnitude of this effect on alcohol-related clinical symptoms and behaviours.” They discretely overlook this meta-analysis from 2009 (and several others which even their rudimentary search would have identified):

Nineteen electronic databases, including English, Korean, Japanese, and Chinese databases, were systematically searched for RCTs of acupuncture for alcohol dependence up to June 2008 with no language restrictions. The methodological qualities of eligible studies were assessed using the criteria described in the Cochrane Handbook.

Eleven studies, which comprised a total of 1,110 individual cases, were systematically reviewed. Only 2 of 11 trials reported satisfactorily all quality criteria. Four trials comparing acupuncture treatment and sham treatments reported data for alcohol craving. Three studies reported that there were no significant differences. Among 4 trials comparing acupuncture and no acupuncture with conventional therapies, 3 reported significant reductions. No differences between acupuncture and sham treatments were found for completion rates (Risk Ratio = 1.07, 95% confidence interval, CI = 0.91 to 1.25) or acupuncture and no acupuncture (Risk Ratio = 1.15, 95% CI = 0.79 to 1.67). Only 3 RCTs reported acupuncture-related adverse events, which were mostly minimal.

The results of the included studies were equivocal, and the poor methodological quality and the limited number of the trials do not allow any conclusion about the efficacy of acupuncture for treatment of alcohol dependence. More research and well-designed, rigorous, and large clinical trials are necessary to address these issues.

One does not need to be an expert in interpreting meta-analyses, I think, to see that this paper is more rigorous than the new ones (which incidentally were published in the very dubious journals). And this is why I trust the conclusions of this last-named meta-analysis more than those of the new one: the efficacy of acupuncture remains unproven. And this means that we should not employ or promote it for routine care.

The aim of this paper was to systematically review effectiveness, safety, and robustness of evidence for complementary and alternative medicine in managing premature ejaculation (PE). Nine databases were searched through September 2015. Randomized controlled trials (RCTs) evaluating complementary and alternative medicine for PE were included. Studies were included if they reported on intravaginal ejaculatory latency time (IELT) and/or another validated PE measurement. Adverse effects were summarized.

Ten RCTs were included. Two assessed acupuncture, five assessed Chinese herbal medicine, one assessed Ayurvedic herbal medicine, and two assessed topical “severance secret” cream. Risk of bias was unclear in all studies because of unclear allocation concealment or blinding, and only five studies reported stopwatch-measured IELT. Acupuncture slightly increased IELT over placebo in one study (mean difference [MD] = 0.55 minute, P = .001). In another study, Ayurvedic herbal medicine slightly increased IELT over placebo (MD = 0.80 minute, P = .001). Topical severance secret cream increased IELT over placebo in two studies (MD = 8.60 minutes, P < .001), although inclusion criteria were broad (IELT < 3 minutes). Three studies comparing Chinese herbal medicine with selective serotonin reuptake inhibitors (SSRIs) favored SSRIs (MD = 1.01 minutes, P = .02). However, combination treatment with Chinese medicine plus SSRIs improved IELT over SSRIs alone (two studies; MD = 1.92 minutes, P < .00001) and over Chinese medicine alone (two studies; MD = 2.52 minutes, P < .00001). Adverse effects were not consistently assessed but where reported were generally mild.

The authors concluded that there is preliminary evidence for the effectiveness of acupuncture, Chinese herbal medicine, Ayurvedic herbal medicine, and topical severance secret cream in improving IELT and other outcomes. However, results are based on clinically heterogeneous studies of unclear quality. There are sparse data on adverse effects or potential for drug interactions. Further well-conducted randomized controlled trials would be valuable.

One has to be an optimist to agree that this constitutes ‘preliminary evidence for the effectiveness of acupuncture, Chinese herbal medicine, Ayurvedic herbal medicine, and topical severance secret cream in improving IELT and other outcomes.’ In the discussion section, the authors stress that  “…all 10 studies were classed as having an overall unclear risk of bias because of unclear reporting of allocation concealment (all 10 studies) and unclear blinding of participants and personnel (five studies).” This hardly allows even a preliminary conclusion, in my view.

So, what DOES this review show? I think it demonstrates that

  • alternative therapies are being touted and occasionally tested for even the most unlikely conditions,
  • the quality of the studies is generally too poor to justify the research (particularly in an area as intrusive as PE),
  • clinical trials often seem to be used not for finding answers but for promotion,
  • in alternative medicine, trialists regularly violate research ethics by failing to report adverse effects.



George Lewith has died on 17 March, aged 67. He was one of the most productive researchers of alternative medicine in the UK; specifically he was interested in acupuncture. If you search this blog, you find several posts that mention him or are entirely dedicated to his work. Undeniably, my own views and research were often very much at odds with those of Lewith.

Wikipedia informs us that Lewith graduated from Trinity College, Cambridge in medicine and biochemistry.  He then went on to Westminster Medical School to complete his clinical studies and began working clinically in 1974. In 1977 Lewith became a member of the Royal College of Physicians. Then, in 1980, he became a member of the Royal College of General Practitioners and, later in 1999, was elected a fellow of the Royal College of Physicians.

He was a Professor of Health Research in the Department of Primary Care at the University of Southampton and a director of the International Society for Complementary Medicine Research. Lewith has obtained a significant number of institutional peer reviewed fellowships at doctoral and post-doctoral level and has been principal investigator or collaborator in research grants totally over £5 million during the last decade.

Between 1980 and 2010, Lewith was a partner at the Centre for Complementary and Integrated Medicine, a private practice providing complementary treatments with clinics in London and Southampton.

A tribute by the British Acupuncture Council is poignant, in my view: “George was a friend not only to all of the acupuncture profession, be it traditional, medical or physiotherapist – he was a member of all three professional bodies – but to the whole of complementary medicine. As well as being a research leader he was also politically savvy, working tirelessly up front and behind the scenes to try to bring acupuncture and CAM further into the mainstream. Nobody did more.”

I find it poignant because it hints at the many differences I (and many others) had with Lewith during the last 25 years that I knew him. George was foremost a proponent of acupuncture. His 1985 book – the first of many – advocated treating many internal diseases with acupuncture!

George did not strike me as someone who had the ability or even the ambition to use science for finding the truth and for falsifying hypotheses; in my view, he employed it to confirm his almost evangelic belief. In the pursuit of this all-important aim he did indeed spend a lot of time and energy pulling strings, including on the political level. George was undoubtedly successful but the question has to be asked to what extent this was due to his tireless work ‘behind the scenes’.

In my view, George was a typical example of someone who first and foremost was an advocate and a researcher second. During my time in Exeter, I have met numerous co-workers who had the same problem. Almost without exception, I found that it is impossible to turn such a person into a decent scientist. The advocacy of alternative medicine always got in the way of objectivity and rationality, qualities that are, of course, essential for good science.

George’s very first publication on acupuncture was a ‘letter to the editor’ published in the BMJ. In it, he announced that he is planning to conduct a trial of acupuncture and stated that “acupuncture will be compared to an equally magical placebo”. Yes, George always had the ability to make me laugh; and this is why I will miss him.
