Of all alternative treatments, aromatherapy (i.e. the application of essential oils to the body, usually by gentle massage or simply inhalation) seems to be the most popular. This is perhaps understandable because it certainly is an agreeable form of ‘pampering’ for someone in need of come TLC. But is aromatherapy more than that? Is it truly a ‘THERAPY’?

A recent systematic review was aimed at evaluating the existing data on aromatherapy interventions as a means of improving the quality of sleep. Electronic literature searches were performed to identify relevant studies published between 2000 and August 2013. Randomized controlled and quasi-experimental trials that included aromatherapy for the improvement of sleep quality were considered for inclusion. Of the 245 publications identified, 13 studies met the inclusion criteria, and 12 studies could be used for a meta-analysis.

The meta-analysis of the 12 studies revealed that the use of aromatherapy was effective in improving sleep quality. Subgroup analysis showed that inhalation aromatherapy was more effective than aromatherapy applied via massage.

The authors concluded that readily available aromatherapy treatments appear to be effective and promote sleep. Thus, it is essential to develop specific guidelines for the efficient use of aromatherapy.

Perfect! Let’s all rush out and get some essential oils for inhalation to improve our sleep (remarkably, the results imply that aroma therapists are redundant!).

Not so fast! As I see it, there are several important caveats we might want to consider before spending our money this way:

  1. Why did this review focus on such a small time-frame? (Systematic reviews should include all the available evidence of a pre-defined quality.)
  2. The quality of the included studies was often very poor, and therefore the overall conclusion cannot be definitive.
  3. The effect size of armoatherapy is small. In 2000, we published a similar review and concluded that aromatherapy has a mild, transient anxiolytic effect. Based on a critical assessment of the six studies relating to relaxation, the effects of aromatherapy are probably not strong enough for it to be considered for the treatment of anxiety. The hypothesis that it is effective for any other indication is not supported by the findings of rigorous clinical trials.
  4. It seems uncertain which essential oil is best suited for this indication.
  5. Aromatherapy is not always entirely free of risks. Another of our reviews showed that aromatherapy has the potential to cause adverse effects some of which are serious. Their frequency remains unknown. Lack of sufficiently convincing evidence regarding the effectiveness of aromatherapy combined with its potential to cause adverse effects questions the usefulness of this modality in any condition.
  6. There are several effective ways for improving sleep when needed; we need to know how aromatherapy compares to established treatments for that indication.

All in all, I think stronger evidence is required that aromatherapy is more that pampering.


This article is hilarious, I think. It was written by Heike Bishop, a homeopath who works in Australia. Here she tries to advise colleagues how best to defend homeopathy and how to deal effectively with the increasingly outspoken criticism of homeopathy. Below is the decisive passage from her article; I have not changed or omitted a word, not even her grammatical or other mistakes [only the numbers in brackets were inserted by me; they refer to my comments added below]:

Getting up in the morning and hearing that all the television and radio station report that it is dangerous for people to see their homoeopath, is utterly heart breaking. Even more so because I grew up in East Germany where the government suppressed free speech and anything that was off the beaten path [1]. So what can we do in times like these?

First of all, watch out for Government inquiries. History has shown that they are usually not favourable towards homoeopathy [2] unless you live in Switzerland [3]. It is vitally important in times like these to put differences aside amongst our professional peers. Every association should be mobilised to take an active and ONGOING role to educate and advertise the benefits of homoeopathy [4]. If things have gone too far already, talk about freedom of choice [5]. Write articles and join blogs talking about what you can do specifically for certain conditions [6].  Encourage your patients to tell their success stories in blogs and other social media forums [7]. It is in most cases utterly useless to engage in any conversation [8] online with trolls [9].

Try to develop a calloused skin when it comes to criticism. Your patients don’t want to hear how difficult it is to be a homeopath [10], they want you to be in control and to be reassured that their treatment continues [11]. When someone asks you to comment on an attack on homoeopathy, put your best smile on and state how threatened the pharmaceutical industry must be to resort to such tactics [12].

Staphysagria is indeed a good remedy. Hahnemann also knew its benefits and even alternated it with Arsenicum the day his first wife died and he got a letter that the hospital built in his name allowed patients to choose their treatment between allopathy and homoeopathy [13]. That was the only time he took two remedies on the same day! [14]

Find out what you can about your country’s own internet trolls [15]. However, don’t underestimate their effectiveness in swaying popular opinion [16]. There is no denying that their methods are very effective [17]. It doesn’t matter how ludicrous their comments are, don’t go into direct explanation [18]. Learn from the enemy [19] and repeat a positive message over and over again so it can’t be contorted [20].

Our colleges should support post-graduate studies featuring marketing and media courses [21]. I once met a Homoeopath from the UK and she pointed out that part of the training in the UK is for students to hold homoeopathic first aid courses to promote homoeopathy [22]. Everyone is different – some of us are happy to stand in front of an audience others choose the pen as their sword [23]. The main thing is to do something to save the image of our healing art [24].

  1. Is she implying that facing criticism of homeopathy is akin to living in a totalitarian state? Or that criticism is a violation of free speech?
  2. I wonder why this is so – nothing to do with the evidence, I presume?
  3. Does she refer to the famous ‘Swiss Government report’ which was not by the Swiss Government at all?
  4. ‘Advertise and educate’ seems to be homeopathic speak for ‘MISLEAD’
  5. Good idea! Freedom of choice is a perfect argument (in this case, my choice would be to have a bottle of champagne at around 6 pm every day – on the NHS, of course).
  6. Certain conditions??? And I thought homeopaths do not treat conditions, only whole people.
  7. And forbid them to disclose stories where things did not work out quite so well?
  8. Very wise! Conversations are fraught with the danger of being found wrong.
  9. Critics are not critics but ‘trolls’ – makes sense.
  10. I would have thought that practising as a homeopath is not difficult at all – in most countries, they don’t even check whether you can spell the name correctly.
  11. Is it not rather the homeopath who wants the treatment to continue – after all, it is her livelihood?
  12. Ah yes, BIG PHARMA, the last resort of any quack!
  13. Did she not just praise patient choice as an important virtue?
  14. Hahnemann was famously cantankerous and argumentative all his life; does that mean that his remedies did not work?
  15. Homeopaths might need that for your ad hominem attacks.
  16. Never underestimate the power of truth!!!
  17. This might show that it is you and not the ‘trolls’ who are ludicrous.
  18. Particularly as there are no direct explanations for homeopathy.
  19. First the critics were ‘trolls’, now they have been upgraded to ‘enemy’! Is it really a war?
  20. You need to repeat it at least regularly so that eventually you believe it yourself.
  21. Are marketing and media a substitute for evidence?
  22. Really, first aid? Do homeopaths know what this is? Obviously not!
  23. But real clinicians, homeopaths call them allopaths, are quite happy simply with effective treatments that help patients to improve.
  24. And I thought the main thing was to treat patients with the most effective therapies available.


There is, of course, a very serious message in all of this: when under pressure, homeopaths seem to think of all sorts of things in their (and homeopathy’s) defense – some more rational than others – but the ideas that criticism might be a good way to generate progress, and that a factual debate about the known facts might improve healthcare, do not seem to be amongst them.

Homeopathy is very popular in India – at least this is what we are being told over and over again. The notion goes as far as some sources assuming that homeopathy is quintessential Indian (see below). One Website, informs us that homeopathy is the third most popular method of treatment in India, after Allopathy and Ayurveda. It is estimated that there are about quarter million homeopaths in India. Nearly 10,000 new ones add to this number every year. The legal status of homeopathy in India is very much at par with the conventional medicine.

Another website currently advises the Indian population as well as heath tourists from abroad about homeopathy in the following terms:

Homeopathic medicines have various benefits. Some of them are as follows:

  • Such medicines can be given to infants, children, pregnant or nursing woman
  • If by chance, wrong medication is prescribed, it is not going to have any ill-effect
  • These medicines can be taken along with other medications
  • Homeopathic treatment can be used by anyone
  • The medicines work on the eradication of the symptoms so that illness never comes back
  • These medicines can be stored for a longer span of time and are inexpensive as well
  • Homeopathy has a holistic approach and deals with mind, body and emotions
  • These medicines are non-invasive and extremely effective
  • These medicines can be administered easily
  • Homeopathy useful in a number of health problems

Homeopathic Remedies, for Diseases and Conditions

  • Asthma
  • Arthritis
  • Cancer
  • Acute fevers
  • Sore throats
  • Toothache
  • Eczema
  • Mild depression
  • Fatigue
  • Anxiety
  • Cataract
  • Fractures
  • Injuries with blunt objects
  • Loss of appetite

But is it really true that so many Indian consumers swear by homeopathy, or is that just one of the many myths from the realm of quackery that stubbornly refuse to disappear ?

survey recently conducted by Indian National Sample Survey Office might provide some answers. It revealed that 90 per cent of the Indian population rely on conventional medicine. Merely 6% trusted what the investigators chose to call ‘Indian systems of medicine’, e. g. ayurveda, unani and siddha, homeopathy and yoga and naturopathy.

Odd? Not really! There are several plausible explanations for this apparent contradiction:

  1. The popularity of homeopathy in India could be a myth promoted by apologists.
  2. The figures could be correct, and many Indian patients could use homeopathy not because they believe in it but because they cannot afford effective treatments.
  3. The claim of homeopathy’s popularity could refer to the past, while the recent survey clearly relates to the present.

Whatever the true answer might be, I think this little news story is an instructive example for the fact that the ‘argumentum ad populum’ is a fallacy that easily can mislead us.

For ‘my’ journal FACT, I review all the new articles that have emerged on the subject of alternative medicine on a monthly basis. Here are a few impressions and concerns that this activity have generated:

  • The number of papers on alternative medicine has increased beyond belief: between the year 2000 and 2010, there was a slow, linear increase from 335 to 610 Medline-listed articles; thereafter, the numbers exploded to 1189 (2011), 1674 (2012) and 2236 (2013).
  • This fast growing and highly lucrative ‘market’ has been cornered mainly by one journal: ‘EVIDENCE BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE’ (EBCAM), a journal that I mentioned several times before (see here, for instance). In 2010, EBCAM published 76 papers, while these figures increased to 546, 880 and 1327 during the following three years.
  • Undeniably, this is big business, as authors have to pay tidy sums each time they get published in EBCAM.
  • The peer-review system of EBCAM is farcical: potential authors who send their submissions to EBCAM are invited to suggest their preferred reviewers who subsequently are almost invariably appointed to do the job. It goes without saying that such a system is prone to all sorts of serious failures; in fact, this is not peer-review at all, in my opinion, it is an unethical sham.
  • As a result, most (I estimate around 80%) of the articles that currently get published on alternative medicine are useless rubbish. They tend to be either pre-clinical investigations which never get followed up and are thus meaningless, or surveys of no relevance whatsoever, or pilot studies that never are succeeded by more definitive trials, or non-systematic reviews that are wide open to bias and can only mislead the reader.
  • Nowadays, very few articles on alternative medicine are good enough to get published in mainstream journals of high standing.

The consequences of these fairly recent developments are serious:

  • Conventional scientists and clinicians must get the impression that there is little research activity in alternative medicine (while, in fact, there is lots) and that the little research that does emerge is of poor quality.
  • Consequently alternative medicine will be deemed by those who are not directly involved in it as trivial, and the alternative medicine journals will be ignored or even become their laughing stock.
  • At the same time, the field of alternative medicine and its proponents (the only ones who might actually be reading the plethora of rubbish published in alternative medicine journals) will get more and more convinced that their field is supported by an ever- abundance of peer-reviewed, robust science.
  • Gradually, they will become less and less aware of the standards and requirements that need to be met for evidence to be called reliable (provided they ever had such knowledge in the first place).
  • They might thus get increasingly frustrated by the lack of acceptance of their ‘advances’ by proper scientists – an attitude which, from their perspective, must seem unfair, biased and hostile.
  • In the end, conventional and alternative medicine, rather than learning from each other, will move further and further apart.
  • Substantial amounts of money will continue to be wasted for research into alternative medicine that, whenever assessed critically, turns out to be too poor to advance healthcare in any meaningful way.
  • The ones who medicine should be all about, namely the patients who need our help and rely on the progress of research, are not well served by these developments.

In essence this suggests, I think, that alternative medicine is ill-advised and short-sighted to settle for standards that are so clearly below those generally deemed acceptable in medicine. Similarly, conventional medicine does a serious disfavour to progress and to us all, if it ignores or tolerates this process.

I am not at all sure how to reverse this trend. In the long-term, it would require a change of attitude that obviously is far from easy to bring about. In the short-term, it might help, I think, to de-list journals from Medline that are in such obvious conflict with publication ethics.

This post is dedicated to all homeopathic character assassins.

Some ardent homeopathy fans have reminded me that, some 25  years ago, I published (OH, WHAT A SCANDAL!!!) a positive trial of homeopathy; I even found a website that proudly announces this fact. Homeopaths seem jubilant about this discovery (not because they now need to revise their allegations that I never did any trials; or the other, equally popular claim, that I have always been squarely against their trade but) because the implication is that even I have to concede that homeopathic remedies are better than placebo. In their view, this seems to beg the following important and embarrassing questions:

  • Why did I change my mind?
  • Am I not contradicting myself?
  • Who has bribed me?
  • Am I in the pocket of Big Pharma?
  • Does this ‘skeleton in my closet’ discredit me for all times?

I remember the trial in question quite well. We conducted it during my time in Vienna, and I am proud of several innovative ideas that went into it. Here is the abstract in full:

The aim of this study was to test the effectiveness of a combined homeopathic medication in primary varicosity. A well-defined population of 61 patients was randomized into active medication (Poikiven®) or placebo. Both were given for 24 d. At the start of the trial, after 12 d medication and at the end of the study, objective and subjective parameters were recorded: venous filling time, leg volume, calf circumference, haemorheological measurements and patients’ symptoms such as cramps, itching, leg heaviness, pain during standing and the need to elevate the legs. The results show that venous filling time is changed by 44% towards normal in the actively-treated group. The average leg volume fell significantly more in this group, but calf circumferences did not change significantly and blood rheology was not altered in any relevant way. None of the patients reported side-effects. Subjective complaints were relieved significantly more by Poikiven than by placebo. These results suggest that the oral treatment of primary varicosity using Poikiven is feasible.

So, there we have it: a homeopathic remedy (as tested by me) is clearly better than placebo normalising important objective parameters as well as subjective symptoms of varicose veins. Is that not a contradiction of what I keep saying today, namely that homeopathy is a placebo therapy?

YES AND NO! (But much more NO than YES)

Yes, because that was clearly our result, and I never tried to deny it.

No, because our verum was far from being a homeopathic, highly diluted remedy. It contained Aesculus D1 12,5 ml, Arnica D1 2,5 ml, Carduus marianus D1 5 ml, Hamamelis D1 10 ml, Lachesis D6 5 ml, Lycopodium D4 5 ml, Melilotus officinalis D1 10 ml. Take just the first of these ingredients, Aesculus or horse chestnut. This is a herbal medicine that has been well documented (even via a Cochrane review) to be effective for the symptoms of varicose veins, and it contains Aesculus in the D1 potency. This means that it is diluted merely by a factor of 1:10. So, for all intents and purposes, our verum was herbal by nature, and there is no surprise at all that we found it to be effective.

[Here is a little ‘aside’: Aesculus is a proven treatment for varicose veins. Homeopathy must always rely on the ‘like cures like’ principle. Therefore, if Aesculus had been used in the homeopathic way, would it not, according to homeopathic dogma, had to worsen the symptoms of our patients rather than alleviating them?]

All of this would be trivial to the extreme, if it did not touch upon an important and confusing point which is often used as an ‘escape route’ by homeopaths when they find themselves between a rock and a hard place. Some trials of homeopathy are positive because they use medications which are homeopathic only by name. This regularly creates considerable confusion. In the recent BMJ debate I tried to address this issue head on by stating at the outset: ” Nobody questions, of course, that some substances used in homeopathy, such as arsenic or strychnine, can be pharmacologically active, but homeopathic medicines are typically far too dilute to have any effect.”

And that’s the point: homeopathic remedies beyond a C12 potency contain nothing, less dilute ones contain little to very little, and D1 potencies are hardy diluted at all and thus contain substantial amounts of active ingredients. Such low potencies are rarely used by homeopaths and should be called PSEUDO-HOMEOPATHIC, in my view. Homeopaths tend to use this confusing complexity to wriggle out of difficult arguments, and often they rely on systematic reviews of homeopathic trials which can generate somewhat confusing overall findings because of such PSEUDO-HOMEOPATHIC remedies.

To make it perfectly clear: the typical homeopathic remedy is far too dilute to have any effect. When scientists or the public at large speak of homeopathic remedies, we don’t mean extracts of Aesculus or potent poisons like Arsenic D1 (has anyone heard of someone claiming to have killed rats with homeopathy?); we refer to the vast majority of remedies which are highly dilute and contain no or very few active molecules – even when we do not explain this somewhat complicated and rather tedious circumstance each and every time. I therefore declare once and for all that, unless I indicate otherwise, I do NOT mean potencies below C6 when I speak of a ‘homeopathic remedy’ (sorry homeopathy fans, perhaps I should have done this when I started this blog).

What if our Vienna study all those years ago had tested not the pseudo-homeopathic ‘Poikiven’ but a highly dilute, real homeopathic remedy and had still come up with a positive finding? Would that make me inconsistent, dishonest, untrustworthy or corrupt? Certainly not!

I have always urged people to not go by the results of single trials. There are numerous reasons why a single study can produce a misleading result. We should therefore, wherever possible, rely on systematic reviews that critically evaluate the totality of the evidence (I would always mistrust even my own trial data, if it contradicted the totality of the reliable evidence) – and such analyses clearly fail to show that homeopathy is more than a placebo.

And even, if none of this had happened, and I had just changed my mind about homeopathy because

  • the evidence changed,
  • I had become wiser,
  • I had learnt how to think like a scientist,
  • I had managed to see behind the smokescreen many homeopaths put up to hide the truth?

Would that discredit me? I don’t think so! As someone once said, being able to change one’s mind is a sign of intelligence.

I am sure that the weird world of homeopathic character assassination will soon find something else to discredit me – but for now…


Chiropractors are back pain specialists, they say. They do not pretend to treat non-spinal conditions, they claim.

If such notions were true, why are so many of them still misleading the public? Why do many chiropractors pretend to be primary care physicians who can take care of most illnesses regardless of any connection with the spine? Why do they continue to happily promote bogus treatments? Why do chiropractors, for instance, claim they can treat gastrointestinal diseases?

This recent narrative review of the literature, for example, was aimed at summarising studies describing the management of disorders of the gastrointestinal (GI) tract using ‘chiropractic therapy’ broadly defined here as spinal manipulation therapy, mobilizations, soft tissue therapy, modalities and stretches.

Twenty-one articles were found through searching the published literature to meet the authors’ inclusion criteria. The retrieved articles included case reports to clinical trials to review articles. The majority of articles chronicling patient experiences under chiropractic care reported that they experienced mild to moderate improvements in GI symptoms. No adverse effects were reported.

From this, the authors concluded that chiropractic care can be considered as an adjunctive therapy for patients with various GI conditions providing there are no co-morbidities.

I think, we would need to look for a long time to find an article with conclusions that are more ridiculous, false and unethical than these.

The old adage applies: rubbish in, rubbish out. If we include unreliable reports such as anecdotes, our finding will be unreliable as well. If we do not make this mistake and conduct a proper systematic review, we will arrive at very different conclusions. My own systematic review, for instance, of controlled clinical trials drew the following conclusion: There is no supportive evidence that chiropractic is an effective treatment for gastrointestinal disorders.


The BMJ is my favourite medical journal by far; I think it is full of good science as well as entertaining to read, and I look forward to finding it in my letter box every Friday. It is thus hard for me to criticise the BMJ, and this is not made easier by the fact that I am the author of one of the two pieces in question. However, the current ‘HEAD TO HEAD’ entitled ‘SHOULD DOCTORS RECOMMEND HOMEOPATHY’ does, in my view, not mark the finest hour of this journal. Let me explain why.

The first question that arises is whether homeopathy is a good subject for such a debate. As several commentators have pointed out, it is not – the debate has long been closed; to serious scientists and many doctors, homeopathy tends to be a subject that is nothing more than an odd, obsolete triviality that does not even deserve a mention in the BMJ or any other serious publication. In a way, this notion has almost been proven wrong by the high level of interest the subject quickly generated. So, I will not dwell on this point any longer.

The second issue that arises just from nothing more than merely reading the title of the debate is that the question posed is imprecise. ‘Homeopathy’ is too broad a term for a focussed discussion; it includes amongst other phenomena empathetic encounters, remedies with material doses of highly active ingredients (e.g. Arsenic D1) and remedies that contain absolutely nothing at all (any ‘potency’ beyond C12). In my piece, I tried to make it clear that I speak mostly about ultra-molecular dilutions. This is less obvious in Peter Fisher’s article, and there is doubtlessly a lot of confusion in the debate as well as the comments that follow.

The two articles had to be written without either author knowing the text of the other. Consequently the issues raised by one author were not necessarily addressed by the other. This is somewhat frustrating, as it fails to clarify issues that could easily have been dealt with. In a previous post, I have already explained that the peer-review process of the two articles was seriously flawed. It failed to correct the many misleading statements in Fisher’s piece, as Alan Henness has pointed out in his response both in the BMJ and on this blog. In fact, reading Fisher’s article, I fail to find a single passage that is not factually wrong or highly misleading (the accompanying podcast is even worse, in my view). To me it is obvious that the debate about homeopathy cannot advance, if one side continues to behave in this fashion.

Homeopaths are very adept at recruiting ‘grass roots’ for public relation activities. We know this from various previous experiences. It was therefore predictable that this would swiftly get organised also in this instance. I happen to know from more than one source that there was a highly active campaign by homeopaths trying to persuade their supporters to post responses on the BMJ site and to vote on the BMJ straw poll (scientists, by contrast, know that such polls are silly gadgets and tend to view homeopathy as a triviality that is not worth the effort). In this way, they try to generate the impression that the majority of the public stands firmly behind homeopathy and want doctors to recommend it. It does not need too much to realise that popularity is not a measure of efficacy. Homeopaths, however, tend to relish logical fallacies and therefore will rejoice at such nonsense and celebrate it as their very own victory.

So, was this ‘HEAD TO HEAD’ a mistake? Should I have refused to participate? With hindsight, perhaps. My main reason for accepting was that, had I declined the offer, someone else would have written the piece (there are plenty of excellent scientists who could do an excellent job at this). As sure as hell, that person would subsequently gotten attacked for not ever having researched and/or practiced homeopathy (in the podcast, Fisher even tried to undermine my authority by pointing out that 1) I have not worked as a clinician for decades and 2) I have no NHS contract). I think I may be one of the few critics of homeopathy who cannot possibly be accused of not knowing enough about homeopathy to discuss the subject.

My hope is that, because the BMJ is such an excellent journal, the two articles will survive the current hoo-hah and some people will read them carefully, look up and study the references, analyse all this critically and weigh the arguments responsibly. Then they must be able to discern the fiction from the facts. And in this case, perhaps it was worth it after all.

The ‘Homeopathy Action Trust’ (HAT) is a charity that claims to encourage and support public understanding of homeopathy. They believe that homeopathy is invaluable to many people and plays an important role in maintaining their health and wellbeing. The HAT advocates that patients have a right to choose homeopathic treatments and access to it on the NHS or privately. Many of HAT’s projects are about promoting to use of homeopathy in Africa, for instance, where they advocate homeopathy as a treatment for all sorts of serious diseases.

Recently HAT embarked on another project: a campaign against the current Wiki-page on homeopathy which HAT believes to be biased against homeopathy. Thus they issued a ‘position statement’ on their website. Here is a short paragraph from that statement which I find worthy of a comment (the numbers were inserted by me and refer to my comments below; otherwise the text in bold is by HAT):

We acknowledge that the scientific evidence in support of Homeopathy remains inconclusive (1), but it is by no means definitively negative (2) and there is in fact an active and growing field of research worldwide (3). We acknowledge that the mechanism of action of homeopathic remedies is unknown (4) – as it is for some conventional medicines – but this does not preclude their usage in clinical situations (5). We welcome honest and open-minded debate (6) about Homeopathy and fully support the call for high quality (7), appropriately designed research studies (8) into the effectiveness of homeopathy as it is practised by both medical and professional homeopaths (9).

  1. The evidence is not ‘inconclusive’ but the most reliable evidence fails to convincingly show efficacy (see here, for instance).
  2. In healthcare, we do not focus on the question whether the evidence for anything is ‘definitely negative’, but we base our decisions on the question whether or not the evidence is positive. In other words, we use those treatments that are backed up with positive evidence and not those where this is in serious doubt.
  3. The research activity in homeopathy has been in decline for some time; this can easily be verified by searching Medline.
  4. No, we know that there cannot be a mechanism of action that is in line with the laws of nature.
  5. If such therapies are used in conventional healthcare, it is because they are (contrary to homeopathy) supported by sufficiently strong clinical evidence.
  6. So far, this ‘position statement’ is neither honest nor open-minded, in my view.
  7. More research seems unnecessary, perhaps even unethical, and most research in this area is not of high quality.
  8. ‘Appropriately designed’ sounds frightfully suspicious to me, because homeopaths tend to see any trial that fails to confirm their bizarre notions as ‘not appropriately designed’.
  9. ‘Professional homeopath’ is a term designed to mislead the public; lay homeopaths would be more to the point, I think.

I will state my position up front: THERE IS NO CHILDHOOD CONDITION FOR WHICH CHIROPRACTIC SPINAL MANIPULATION GENERATES MORE GOOD THAN HARM. What is more, I have published evidence (published herehere, here, and here, for instance) to support this statement. If you disagree with it, this is the place and time to do so – and please don’t forget to cite the evidence that supports your statements.

Given that there is very little reliable evidence in this area, I find it surprising that so many chiropractors continue to treat kids. Not true! I hear some chiropractors shout, we do not often treat children. Who is correct? Clearly, we need data to answer this question.

The objective of a new paper was to investigate characteristics of clinical chiropractic practice, including the age of pediatric patients, the number of reports of negative side effects (NSEs), the opinions of doctors of chiropractic on treatment options by patient age groups, the conditions seen and the number of treatment sessions delivered by conditions and by patient age.

An Internet cross-sectional survey was conducted in 20 European countries with 4109 chiropractors invited to reply. The 19 national associations belonging to the European Chiropractic Union and the Danish Chiropractic Association were asked to participate. Respondents were asked to self-report characteristics of their practices.

Of the 956 (23.3%) participating chiropractors, 921 reported 19821 pediatric patients per month. Children represented 8.1% of chiropractors’ total patient load over the last year. A total of 557 (534 mild, 23 moderate, and 0 severe) negative (adverse) side effects were reported for an estimated incidence of 0.23%. On the given treatment statements, chiropractors reported varying agreement and disagreement rates based on patient age. The 8309 answers on conditions were grouped into skeletal (57.0%), neurologic (23.7%), gastrointestinal (12.4%), infection (3.5%), genitourinary (1.5%), immune (1.4%), and miscellaneous conditions (0.5%). The number of treatment sessions delivered varied according to the condition and the patient age.

The authors of this survey concluded that this study showed that European chiropractors are active in the care of pediatric patients. Reported conditions were mainly skeletal and neurologic complaints. In this survey, no severe NSEs were reported, and mild NSEs were infrequent.

In my view, a more appropriate conclusion might be that MANY EUROPEAN CHIROPRACTORS ARE ACTIVE IN QUACKERY.

Osteopathy is a difficult subject. In the US, osteopaths are (almost) identical with doctors who have studied conventional medicine and hardly practice any manipulative techniques at all. Elsewhere, osteopaths are alternative healthcare providers specialising in what they like to call ‘osteopathic manipulative therapy’ (OMT). As though this is not confusing enough, osteopaths are doing similar things as chiropractors but are adamant that they are a distinct profession. Despite these assertions, I have seen little to clearly differentiate the two – with one exception perhaps: osteopaths tend to use techniques that are less frequently associated with severe harm.

Despite this confusion, or maybe because of it, we need to ask: DOES OMT WORK?

A recent study was aimed at assessing the effectiveness of OMT on chronic migraineurs using HIT-6 questionnaire, drug consumption, days of migraine, pain intensity and functional disability. All patients admitted to the Department of Neurology of Ancona’s United Hospitals, Italy, with a diagnosis of migraine and without chronic illness, were considered eligible for this 3-armed RCT.

Patients were randomly divided into three (1) OMT+medication therapy, (2) sham+medication therapy and (3) medication therapy only and received 8 treatments during 6 months. Changes in the HIT-6 score were considered as the main outcome measure.

A total of 105 subjects were included. At the end of the study, OMT significantly reduced HIT-6 score, drug consumption, days of migraine, pain intensity and functional disability.

The investigators concluded that these findings suggest that OMT may be considered a valid procedure for the management of migraineurs.

Similar results have been reported elsewhere:

One trial, for instance, concluded: “This study affirms the effects of OMT on migraine headache in regard to decreased pain intensity and the reduction of number of days with migraine as well as working disability, and partly on improvement of HRQoL. Future studies with a larger sample size should reproduce the results with a control group receiving placebo treatment in a long-term follow-up.”

Convinced? No, I am not.

Why? Because the studies that do exist seem a little too good to be true; because they are few and far between, because the few studies tend to be flimsy and have been published in dodgy journals, because they lack independent replications, and because critical reviews seem to conclude that OMT is nowhere near as promising as some osteopaths would like us to believe: “Further studies of improved quality are necessary to more firmly establish the place of physical modalities in the treatment of primary headache disorders. With the exception of high velocity chiropractic manipulation of the neck, the treatments are unlikely to be physically dangerous, although the financial costs and lost treatment opportunity by prescribing potentially ineffective treatment may not be insignificant. In the absence of clear evidence regarding their role in treatment, physicians and patients are advised to make cautious and individualized judgments about the utility of physical treatments for headache management; in most cases, the use of these modalities should complement rather than supplant better-validated forms of therapy.”
