Yes, it is unlikely but true! I once was the hero of the world of energy healing, albeit for a short period only. An amusing story, I hope you agree.
Back in the late 1990s, we had decided to run two trials in this area. One of them was to test the efficacy of distant healing for the removal of ordinary warts, common viral infections of the skin which are quite harmless and usually disappear spontaneously. We had designed a rigorous study, obtained ethics approval and were in the midst of recruiting patients, when I suggested I could be the trial’s first participant, as I had noticed a tiny wart on my left foot. As patient-recruitment was sluggish at that stage, my co-workers consulted the protocol to check whether it might prevent me from taking part in my own trial. They came back with the good news that, as I was not involved in the running of the study, there was no reason for me to be excluded.
The next day, they ‘processed’ me like all the other wart sufferers of our investigation. My wart was measured, photographed and documented. A sealed envelope with my trial number was opened (in my absence, of course) by one of the trialists to see whether I would be in the experimental or the placebo group. The former patients were to receive ‘distant healing’ from a group of 10 experienced healers who had volunteered and felt confident to be able to cure warts. All they needed was a few details about each patients, they had confirmed. The placebo group received no such intervention. ‘Blinding’ the patient was easy in this trial; since they were not themselves involved in any healing-action, they could not know whether they were in the placebo or the verum group.
The treatment period lasted for several weeks during which time my wart was re-evaluated in regular intervals. When I had completed the study, final measurements were done, and I was told that I had been the recipient of ‘healing energy’ from the 10 healers during the past weeks. Not that I had felt any of it, and not that my wart had noticed it either: it was still there, completely unchanged.
I remember not being all that surprised…until, the next morning, when I noticed that my wart had disappeared! Gone without a trace!
Of course, I told my co-workers who were quite excited, re-photographed the spot where the wart had been and consulted the study protocol to determine what had to be done next. It turned out that we had made no provisions for events that might occur after the treatment period.
But somehow, this did not feel right, we all thought. So we decided to make a post-hoc addendum to our protocol which stipulated that all participants of our trial would be asked a few days after the end of the treatment whether any changes to their warts had been noted.
Meanwhile the healers had got wind of the professorial wart’s disappearance. They were delighted and quickly told other colleagues. In no time at all, the world of ‘distant healing’ had agreed that warts often reacted to their intervention with a slight delay – and they were pleased to hear that we had duly amended our protocol to adequately capture this important phenomenon. My ‘honest’ and ‘courageous’ action of acknowledging and documenting the disappearance of my wart was praised, and it was assumed that I was about to prove the efficacy of distant healing.
And that’s how I became their ‘hero’ – the sceptical professor who had now seen the light with his own eyes and experienced on his own body the incredible power of their ‘healing energy’.
Incredible it remained though: I was the only trial participant who lost his wart in this way. When we published this study, we concluded: Distant healing from experienced healers had no effect on the number or size of patients’ warts.
AND THAT’S WHEN I STOPPED BEING THEIR ‘HERO’.
There are numerous types and styles of acupuncture, and the discussion whether one is better than the other has been long, tedious and frustrating. Traditional acupuncturists, for instance, individualise their approach according to their findings of pulse and tongue diagnoses as well as other non-validated diagnostic criteria. Western acupuncturists, by contrast, tend to use formula or standardised treatments according to conventional diagnoses.
This study aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice of a Chinese-born medical doctor trained in both western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups who received either standardized acupuncture or individualized acupuncture. 10 to 15 treatments based on individual symptoms were given with two treatments per week.
The main outcome measure was the area under the curve (AUC) summarizing eight weeks of daily rated pain severity measured with a visual analogue scale. No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7; standardized acupuncture 1482.9; group difference, 285.8).
The authors concluded that individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain.
But perhaps it matters whether the acupuncturist is thoroughly trained or has just picked up his/her skills during a weekend course? I am afraid not: this analysis of a total of 4,084 patients with chronic headache, lower back pain or arthritic pain treated by 1,838 acupuncturists suggested otherwise. There were no differences in success for patients treated by physicians passing through shorter (A diploma) or longer (B diploma) training courses in acupuncture.
But these are just one single trial and one post-hoc analysis of another study which, by definition, cannot be fully definitive. Fortunately, we have more evidence based on much larger numbers. This brand-new meta-analysis aimed to evaluate whether there are characteristics of acupuncture or acupuncturists that are associated with better or worse outcomes.
An existing dataset, developed by the Acupuncture Trialists’ Collaboration, included 29 trials of acupuncture for chronic pain with individual data involving 17,922 patients. The available data on characteristics of acupuncture included style of acupuncture, point prescription, location of needles, use of electrical stimulation and moxibustion, number, frequency and duration of sessions, number of needles used and acupuncturist experience. Random-effects meta-regression was used to test the effect of each characteristic on the main effect estimate of pain. Where sufficient patient-level data were available, patient-level analyses were conducted.
When comparing acupuncture to sham controls, there was little evidence that the effects of acupuncture on pain were modified by any of the acupuncture characteristics evaluated, including style of acupuncture, the number or placement of needles, the number, frequency or duration of sessions, patient-practitioner interactions and the experience of the acupuncturist. When comparing acupuncture to non-acupuncture controls, there was little evidence that these characteristics modified the effect of acupuncture, except better pain outcomes were observed when more needles were used and, from patient level analysis involving a sub-set of 5 trials, when a higher number of acupuncture treatment sessions were provided.
The authors of this meta-analysis concluded that there was little evidence that different characteristics of acupuncture or acupuncturists modified the effect of treatment on pain outcomes. Increased number of needles and more sessions appear to be associated with better outcomes when comparing acupuncture to non-acupuncture controls, suggesting that dose is important. Potential confounders include differences in control group and sample size between trials. Trials to evaluate potentially small differences in outcome associated with different acupuncture characteristics are likely to require large sample sizes.
My reading of these collective findings is that it does not matter which type of acupuncture you use nor who uses it; the clinical effects are similar regardless of the most obvious potential determinants. Hardly surprising! In fact, one would expect such results, if one considered that acupuncture is a placebo-treatment.
A recent interview on alternative medicine for the German magazine DER SPIEGEL prompted well over 500 comments; even though, in the interview, I covered numerous alternative therapies, the discussion that followed focussed almost entirely on homeopathy. Yet again, many of the comments provided a reminder of the quasi-religious faith many people have in homeopathy.
There can, of course, be dozens of reasons for such strong convictions. Yet, in my experience, some seem to be more prevalent and important than others. During my last two decades in researching homeopathy, I think, I have identified several of the most important ones. In this post, I try to outline a typical sequence of events that eventually leads to a faith in homeopathy which is utterly immune to fact and reason.
The starting point of this journey towards homeopathy-worship is usually an impressive personal experience which is often akin to an epiphany (defined as a moment of sudden and great revelation or realization). I have met hundreds of advocates of homeopathy, and those who talk about this sort of thing invariably offer impressive stories about how they metamorphosed from being a ‘sceptic’ (yes, it is truly phenomenal how many believers insist that they started out as sceptics) into someone who was completely bowled over by homeopathy, and how that ‘moment of great revelation’ changed the rest of their lives. Very often, this ‘Saulus-Paulus conversion’ relates to that person’s own (or a close friend’s) illness which allegedly was cured by homeopathy.
Rachel Roberts, chief executive of the Homeopathy Research Institute, provides as good an example of this sort of epiphany as anyone; in an article in THE GUARDIAN, she described her conversion to homeopathy with the following words:
I was a dedicated scientist about to begin a PhD in neuroscience when, out of the blue, homeopathy bit me on the proverbial bottom.
Science had been my passion since I began studying biology with Mr Hopkinson at the age of 11, and by the age of 21, when I attended the dinner party that altered the course of my life, I had still barely heard of it. The idea that I would one day become a homeopath would have seemed ludicrous.
That turning point is etched in my mind. A woman I’d known my entire life told me that a homeopath had successfully treated her when many months of conventional treatment had failed. As a sceptic, I scoffed, but was nonetheless a little intrigued.
She confessed that despite thinking homeopathy was a load of rubbish, she’d finally agreed to an appointment, to stop her daughter nagging. But she was genuinely shocked to find that, after one little pill, within days she felt significantly better. A second tablet, she said, “saw it off completely”.
I admit I ruined that dinner party. I interrogated her about every detail of her diagnosis, previous treatment, time scales, the lot. I thought it through logically – she was intelligent, she wasn’t lying, she had no previous inclination towards alternative medicine, and her reluctance would have diminished any placebo effect.
Scientists are supposed to make unprejudiced observations, then draw conclusions. As I thought about this, I was left with the highly uncomfortable conclusion that homeopathy appeared to have worked. I had to find out more.
So, I started reading about homeopathy, and what I discovered shifted my world for ever. I became convinced enough to hand my coveted PhD studentship over to my best friend and sign on for a three-year, full-time homeopathy training course.
Now, as an experienced homeopath, it is “science” that is biting me on the bottom. I know homeopathy works…
As I said, I have heard many strikingly similar accounts. Some of these tales seem a little too tall to be true and might be a trifle exaggerated, but the consistency of the picture that emerges from all of these stories is nevertheless extraordinary: people get started on a single anecdote which they are prepared to experience as an epiphanic turn-around. Subsequently, they are on a mission of confirming their new-found belief over and over again, until they become undoubting disciples for life.
So what? you might ask. But I do think this epiphany-like event at the outset of a homeopathic career is significant. In no other area of health care does the initial anecdote regularly play such a prominent role. People do not become believers in aspirin, for instance, on the basis of a ‘moment of great revelation’, they may take it because of the evidence. And, if there is a discrepancy between the external evidence and their own experience, as with homeopathy, most people would start to reflect: What other explanations exist to rationalise the anecdote? Invariably, there are many (placebo, natural history of the condition, concomitant events etc.).
Epiphany-stuck believers spends much time and effort to actively look for similar stories that seem to confirm the initial anecdote. They might, for instance, recommend or administer or prescribe homeopathy to others, many of whom would report positive outcomes. At the same time, all anecdotes that do not happen to fit the belief are brushed aside, forgotten, supressed, belittled, decried etc. This process leads to confirmation after confirmation after confirmation – and gradually builds up to what proponents of homeopathy would call ‘years of experience’. And ‘years of experience’ can, of course, not be wrong!
Again, believers neglect to question, doubt and rationalise their own perceptions. They ignore the fact that years of experience might just be little more than a suborn insistence on repeating one’s own mistakes. Even the most obvious confounders such as selective memory or alternative causes for positive clinical outcomes are quickly dismissed or not even considered at all.
Avoiding cognitive dissonance at all cost
But believers still has to somehow deal with the scientific facts about homeopathy; and these are, of course, grossly out of line with their belief. Thus the external evidence and the internal belief would inevitably clash creating a shrill cognitive dissonance. This must be avoided at all cost, as it might threaten the believer’s peace of mind. And the solution is amazingly simple: scientific evidence that does not confirm the believer’s conviction is ignored or, when this proves to be impossible, turned upside down.
Rachel Roberts’ account is most enlightening also in this repect:
And yet I keep reading reports in the media saying that homeopathy doesn’t work and that this scientific evidence doesn’t exist.
The facts, it seems, are being ignored. By the end of 2009, 142 randomised control trials (the gold standard in medical research) comparing homeopathy with placebo or conventional treatment had been published in peer-reviewed journals – 74 were able to draw firm conclusions: 63 were positive for homeopathy and 11 were negative. Five major systematic reviews have also been carried out to analyse the balance of evidence from RCTs of homeopathy – four were positive (Kleijnen, J, et al; Linde, K, et al; Linde, K, et al; Cucherat, M, et al) and one was negative (Shang, A et al). It’s usual to get mixed results when you look at a wide range of research results on one subject, and if these results were from trials measuring the efficacy of “normal” conventional drugs, ratios of 63:11 and 4:1 in favour of a treatment working would be considered pretty persuasive.
This statement is, in my view, a classic example of a desperate misinterpretation of the truth as a means of preventing the believer’s house of cards from collapsing. It even makes the hilarious claim that not the believers but the doubters “ignore” the facts.
In order to be able to adhere to her belief, Roberts needs to rely on a woefully biased white-wash from the ‘British Homeopathic Association’. And, in order to be on the safe side, she even quotes it misleadingly. The conclusion of the Cucherat review, for instance, can only be seen as positive by most blinkered of minds: There is some evidence that homeopathic treatments are more effective than placebo; however, the strength of this evidence is low because of the low methodological quality of the trials. Studies of high methodological quality were more likely to be negative than the lower quality studies. Further high quality studies are needed to confirm these results. Contrary to what Roberts states, there are at least a dozen more than 5 systematic reviews of homeopathy; my own systematic review of systematic reviews, for example, concluded that the best clinical evidence for homeopathy available to date does not warrant positive recommendations for its use in clinical practice.
It seems that, at this stage of a believer’s development, the truth gets all too happily sacrificed on the altar of faith. All these ‘ex-sceptics’ turned believers are now able to display is a rather comical parody of scepticism.
The delusional end-stage
The last stage in the career of a believer has been reached when hardly anything that he or she is convinced of resembles reality any longer. I don’t know much about Rachel Roberts, and she might not have reached this point yet; but there are many others who clearly have.
My two favourite examples of end-stage homeopathic delusionists are John Benneth and Dana Ullman. The final stage on the journey from ‘sceptic scientist’ to delusional disciple is characterised by an incessant stream of incoherent statements of vile nonsense that beggars belief. It is therefore easy to recognise and, because nobody can possibly take the delusionists seriously, they are best viewed as relatively harmless contributors to medical comedy.
Why does all of this matter?
Many homeopathy-fans are quasi-religious believers who, in my experience, have degressed way beyond reason. It is therefore a complete waste of time trying to reason with them. Initiated by a highly emotional epiphany, their faith cannot be shaken by rational arguments. Similar but usually less pronounced attitudes, I am afraid, can be observed in true believers of other alternative treatments as well (here I have chosen the example of homeopathy mainly because it is the area where things are most explicit).
True believers claim to have started out as sceptics and they often insist to be driven by a scientific mind. Yet I have never seen any evidence for these assumptions. On the contrary, for a relatively trivial episode to become a life-changing epiphany, the believer’s mind needs to be lamentably unscientific, unquestioning and simple.
In my experience, true believers will not change their mind; I have never seen this happening. However, progress might nevertheless be made, if we managed to instil a more (self-) questioning rationality and scientific attitudes into the minds of the next generations. In other words, we need better education in science and more training of critical thinking during their formative years.
What is ear acupressure?
Proponents claim that ear-acupressure is commonly used by Chinese medicine practitioners… It is like acupuncture but does not use needles. Instead, small round pellets are taped to points on one ear. Ear-acupressure is a non-invasive, painless, low cost therapy and no significant side effects have been reported.
Ok, but does it work?
There is a lot of money being made with the claim that ear acupressure (EAP) is effective, especially for smoking cessation; entrepreneurs sell gadgets for applying the pressure on the ear, and practitioners earn their living through telling their patients that this therapy is helpful. There are hundreds of websites with claims like this one: Auricular therapy (Acupressure therapy of the ear region) has been used successfully for Smoking cessation. Auriculotherapy is thought to be 7 times more powerful than other methods used for smoking cessation; a single auriculotherapy treatment has been shown to reduce smoking from 20 or more cigarettes a day down to 3 to 5 a day.
But what does the evidence show?
This new study investigated the efficacy of EAP as a stand-alone intervention for smoking cessation. Adult smokers were randomised to receive EAP specific for smoking cessation (SSEAP) or a non-specific EAP (NSEAP) intervention, EAP at points not typically used for smoking cessation. Participants received 8 weekly treatments and were requested to press the five pellets taped to one ear at least three times per day. Participants were followed up for three months. The primary outcome measures were a 7-day point-prevalence cessation rate confirmed by exhaled carbon monoxide and relief of nicotine withdrawal symptoms (NWS).
Forty-three adult smokers were randomly assigned to SSEAP (n = 20) or NSEAP (n = 23) groups. The dropout rate was high with 19 participants completing the treatments and 12 remaining at followup. One participant from the SSEAP group had confirmed cessation at week 8 and end of followup (5%), but there was no difference between groups for confirmed cessation or NWS. Adverse events were few and minor.
And is there a systematic review of the totality of the evidence?
Sure, the current Cochrane review arrives at the following conclusion: There is no consistent, bias-free evidence that acupuncture, acupressure, laser therapy or electrostimulation are effective for smoking cessation…
Yes, we may well ask! If most TCM practitioners use EAP or acupuncture for smoking cessation telling their customers that it works (and earning good money when doing so), while the evidence fails to show that this is true, what should we say about such behaviour? I don’t know about you, but I find it thoroughly dishonest.
I have been challenged by homeopaths! Not again you might think, but this one is quite interesting.
Some time ago, I gave an interview in which I stated that, for a while, I had assumed homeopaths to be just a little over-enthusiastic but, over the years, I have come to the conclusion that many of them are lying outright (the interview is in German, and I used the term “luegen wie gedruckt”). Predictably, this has prompted fierce opposition from homeopaths who objected to my claim and demand proof of this statement.
So, here I will try to provide some evidence – only SOME because there is far too much for a short post of this nature. To get started, I quickly googled ‘homeopathy’ and, impressively, the very first site already provided me with the following quotes:
None of these statements is true; and if they are not true, they must be lies (defined as “an untrue or deceptive statement deliberately used to mislead“)! Yes, I don’t mean errors, I do mean deliberate lies.
In fact, if we want to find proof for my statement ‘MANY HOMEOPATHS LIE OUTRIGHT’, we are spoilt for choice. For instance, any homeopath who mis-quoted the so-called ‘Swiss report’ on homeopathy as being an official document of the Swiss government even when its true nature had been disclosed over and over again, was clearly telling lies; and Dana Ullman must be the undisputed champion in this respect.
But there is more – much, much more! Homeopaths who promote their placebos as a cure of AIDS or cancer or any other serious disease are not just lying, they are endangering the health of millions. If anyone wants to read about individual homeopaths or organisations that have issued lies, I recommend reading this site which provides plenty of names and interesting links.
I think, I can stop here – but I do invite readers to post their own examples of ‘homeopathic lies’ in the comments below.
Sorry homeopaths, but you did ask for it!
If we ask how effective spinal manipulation is as a treatment of back pain, we get all sorts of answers. Therapists who earn their money with it – mostly chiropractors, osteopaths and physiotherapists – are obviously convinced that it is effective. But if we consult more objective sources, the picture changes dramatically. The current Cochrane review, for instance, arrives at this conclusion: SMT is no more effective in participants with acute low-back pain than inert interventions, sham SMT, or when added to another intervention. SMT also appears to be no better than other recommended therapies.
Such reviews tend to pool all studies together regardless of the nature of the practitioner. But perhaps one type of clinician is better than the next? Certainly many chiropractors are on record claiming that they are the best at spinal manipulations. Yet it is conceivable that physiotherapists who do manipulations without being guided by the myth of ‘adjusting subluxations’ have an advantage over chiropractors. Three very recent systematic reviews might go some way to answer these questions.
The purpose of the first systematic review was to examine the effectiveness of spinal manipulations performed by physiotherapists for the treatment of patients with low back pain. The authors found 6 RCTs that met their inclusion criteria. The most commonly used outcomes were pain rating scales and disability indexes. Notable results included varying degrees of effect sizes favouring spinal manipulations and minimal adverse events resulting from this intervention. Additionally, the manipulation group in one study reported significantly less medication use, health care utilization, and lost work time. The authors concluded that there is evidence to support the use of spinal manipulation by physical therapists in clinical practice. Physical therapy spinal manipulation appears to be a safe intervention that improves clinical outcomes for patients with low back pain.
The second systematic Review was of osteopathic intervention for chronic, non-specific low back pain (CNSLBP). Only two trials met the authors’ inclusion criteria. They had a lack of methodological and clinical homogeneity, precluding a meta-analysis. The trials used different comparators with regards to the primary outcomes, the number of treatments, the duration of treatment and the duration of follow-up. The authors drew the following conclusions: There are only two studies assessing the effect of the manual therapy intervention applied by osteopathic clinicians in adults with CNSLBP. One trial concluded that the osteopathic intervention was similar in effect to a sham intervention, and the other suggests similarity of effect between osteopathic intervention, exercise and physiotherapy. Further clinical trials into this subject are required that have consistent and rigorous methods. These trials need to include an appropriate control and utilise an intervention that reflects actual practice.
The third systematic review sought to determine the benefits of chiropractic treatment and care for back pain on well-being, and aimed to explore to what extent chiropractic treatment and care improve quality of life. The authors identified 6 studies (4 RCTs and two observational studies) of varying quality. There was a high degree of inconsistency and lack of standardisation in measurement instruments and outcome measures. Three studies reported reduced use of other/extra treatments as a positive outcome; two studies reported a positive effect of chiropractic intervention on pain, and two studies reported a positive effect on disability. The authors concluded that it is difficult to defend any conclusion about the impact of chiropractic intervention on the quality of life, lifestyle, health and economic impact on chiropractic patients presenting with back pain.
Yes, yes, yes, I know: the three reviews are not exactly comparable; so we cannot draw firm conclusions from comparing them. Five points seem to emerge nevertheless:
- The evidence for spinal manipulation as a treatment for back pain is generally not brilliant, regardless of the type of therapist.
- There seem to be considerable differences according to the nature of the therapist.
- Physiotherapists seem to have relatively sound evidence to justify their manipulations.
- Chiropractors and osteopaths are not backed by evidence which is as reliable as they so often try to make us believe.
- Considering that the vast majority of serious complications after spinal manipulation has occurred with chiropractors, it would seem that chiropractors are the profession with the worst track record regarding manipulation for back pain.
A recent article by a South African homeopath promoted the concept of homeopaths taking over the role of primary care practitioners. His argument essentially was that, in South Africa, homeopaths are well trained and thus adequately equipped to do this job responsibly. Responsibly, really? You find that hard to believe? Here are the essentials of his arguments including all his references in full. I think they are worth reading.
Currently, the Durban University of Technology (DUT) and the University of Johannesburg (UJ) offer degree’s in homoeopathy. This involves a 5-year full-time theoretical and practical training course, followed by a Master’s level research project. After fulfilment of these criteria, a Master’s Degree in Technology (Homoeopathy) is awarded. The course comprises of a strong core of medical subjects, such as the basic sciences of Anatomy, Physiology, Medical Microbiology, Biochemistry and Epidemiology, and the clinical sciences of Pathology and Diagnostics. This is complemented with subjects in Classical, Clinical and Modern Homoeopathy and Homoeopharmaceutics4,5…
By law, any person practicing homoeopathy in South Africa must be registered with the Allied Health Professions Council of South Africa (AHPCSA). This is essential, as the Council ensures both medical and homoeopathic competency of practitioners, and that the activities of registered practitioners are closely monitored by the Professional Board. The purpose of the AHPCSA is to ensure that only those with legitimate qualifications of a high enough standard are registered and allowed to practice in South Africa, thus protecting the public against any fraudulent behaviour and illegal practitioners. Therefore, in order to ensure effective homoeopathic treatment, it is essential that any person wishing to prescribe homoeopathic medicine or practice homoeopathy in South Africa must be registered as a Homoeopathic Practitioner with the Allied Health Professions Council of South Africa. This includes conventional Medical Practitioners (dual registration is allowed for Medical Practitioners with both the Health Professions Council and AHPCSA)6, as homoeopathy requires several years of training in order to apply effectively in clinical practice…
Registration with the Council affords medico-legal rights similar to those of a medical professional, where treatment is limited to the scope of homoeopathic practice. Thus a homoeopath is firstly a trained diagnostician, and with successful registration with the Council, obtains the title Doctor. A homoeopath is trained and legally obliged to conduct a full medical history, a comprehensive clinical examination, and request further medical investigations, such as blood tests and X-rays, in order to fully assess patients. This is coupled with the ability to consult with specialist pathologists and other medical specialists when necessary, and refer a patient to the appropriate practitioner if the condition falls outside the scope of homoeopathic practice. A homoeopath may also legally issue a certificate of dispensation (‘Doctor’s note’) with appropriate evidence and within reason, and is deemed responsible for the diagnosis and treatment of patients under their care6. A homoeopath is not trained or licensed in any form of surgery, specialist diagnostics (e.g. colonoscopy or angiograms), cannot prescribe prescription medication and is not lawfully allowed to conduct intra-venous treatment of any kind. However, a registered homoeopath is licensed to use intra-muscular homoeopathic injectables in the treatment of various local or systemic complaints when necessary.
Conventional (allopathic) medicine generally targets specific biochemical processes with mostly chemically synthesised medication, in an attempt to suppress a symptom. However, in doing so, this usually negatively affects other biochemical reactions which results in an imbalance within the system. Homoeopathy, by contrast, seeks to re-establish a balance within the natural functioning of the body, restore proper function and results in the reduction or cessation of symptoms. Homoeopathy therefore enables the body to self-regulate and self-heal, a process known as homeostasis that is intrinsic to every living organism.
Conventional medical treatment is by no means risk free. Iatrogenic (medically induced) deaths in the United States are estimated at 786 000 per year, deaths which are considered avoidable by medical doctors7,8. These figures put annual iatrogenic death in the American medical system above that of cardiovascular disease and cancer as the leading cause of death in that country9, a fact that is not widely reported! South African figures are not easily available, but it is likely that we have similar rates. Although conventional medications have a vital role, are sometimes necessary and can of-course be life-saving, all too often too many patients are put on chronic medication when there are numerous effective, natural, safe and scientifically substantiated options available….
According to the World Health Organisation (WHO), homeopathy is the second largest system of medicine in the world, and world-wide use continues to grow in developed and developing nations10. Homoeopathy is widely considered to be safe and effective, with both clinical and laboratory research providing evidence for the efficacy of homoeopathy11. As the range of potential conditions that homoeopathy can treat is almost limitless, and that treatment is not associated with adverse reactions, homoeopathy should be considered a first-line therapy for all ages. As homoeopaths in South Africa are considered primary health care practitioners, if a conventional approach is deemed necessary, and further diagnostics are required, your practitioner will not hesitate to refer you to the appropriate health care practitioner. Homeopathy is also used alongside conventional medicine and any other form of therapy, and should be seen as ‘complementary’ medicine and not ‘alternative’ medicine.
Homoeopathy is an approach that is widely considered to be safe, and when utilised correctly, can be effective for a wide range of conditions. As a primary health care practitioner, a homoeopath is able to handle all aspects of general practice and family health care, including diagnostics, case management and referral to other practitioners or medical specialists. A registered homoeopath is legally responsible to ensure the adequate treatment of their patients, and is accountable for all clinical decisions and advice. A registered homoeopath understands the role of conventional medicine, and will refer to the appropriate specialist in cases that fall outside the legal scope of practice.

I found this article extremely revealing and scary. It gives us an important glimpse into the way some or perhaps even most homeopaths think. They clearly believe that:
1) Their training is sufficient for them to become competent primary care professionals, i.e. clinicians who are the first port of call for sick people to be diagnosed and treated effectively.
2) Homeopathy is scientifically proven to be efficacious for an ‘almost limitless’ range of conditions. Interestingly, not a single reference is provided to support this claim. Nevertheless, homeopath believe it, and that seems to be enough.
3) Homeopaths seem convinced that they perfectly understand real medicine; yet all they really do is to denounce it as one of the biggest killer of mankind.
4) The fact that homeopaths cannot prescribe real medicine is not seen as a hindrance to their role as primary care practitioner; if anything, homeopaths consider this to be an advantage.
5) Homeopaths view registration with some sort of governing body as the ultimate legitimation of their trade. Once such regulatory measures are in place, the need to support any of their claims with evidence is nil and void.
This article did remind me of the wry statement that ‘HOMEOPATHY IS TO MEDICINE WHAT THE CARPET INDUSTRY IS TO AVIATION’. Homeopaths truly live on a different planet, a planet where belief is everything and responsibility is an alien concept. I certainly hope that they will not take over planet earth in a hurry. If I imagine a world where homeopaths dominate primary care in the way it is suggested in this article, I start having nightmares. It seems to me that people who harbour ideas of this type are not just deluded to the point of madness but they are a danger to public health.
Many reader of this blog will remember the libel case of the British Chiropractic Association (BCA) against Simon Singh. Simon had disclosed in a Guardian comment that the BCA was happily promoting bogus chiropractic treatments for 6 paediatric conditions, including infant colic. The BCA not only lost the case but the affair almost destroyed this strange organisation and resulted in an enormous reputational damage of chiropractors worldwide. In an article entitled AFTER THE STORM, the then-president of the BCA later described the defeat in his own words: “in 2009, events in the UK took a turn which was to consume the British Chiropractic Association (BCA) for two years and force the wider profession to confront key issues that for decades had kept it distanced from its medical counterparts and attracting ridicule from its critics…the BCA began one of the darkest periods in its history; one that was ultimately to cost it financially, reputationally and politically…The GCC itself was in an unprecedented situation. Faced with a 1500% rise in complaints, Investigating Committees were assembled to determine whether there was a case to answer…The events of the past two years have exposed a blind adherence to outdated principles amongst a small but significant minority of the profession. Mindful of the adage that it’s the squeaky wheel that gets the grease, the vocalism of this group has ensured that chiropractic is characterised by its critics as unscientific, unsafe and slightly wacky. Claims that the vertebral subluxation complex is the cause of illness and disease have persisted despite the three UK educational establishments advising the GCC that no evidence of acceptable quality exists to support such claims.”
Only a few years AFTER THE STORM, this story seems to have changed beyond recognition. Harald Walach, who is known to readers of this blog because I reported that he was elected ‘pseudo-scientist of the year’ in 2012, recently published a comment on the proceedings of the European Congress of Integrated Medicine where we find the following intriguing version of the libel case:
Mein Freund und Kollege George Lewith aus Southampton hatte einen Hauptvortrag über seine Überblicksarbeit über chiropraktische Interventionen für kleinkindliche Koliken vorgelegt. Sie ist ausgelöst worden durch die Behauptung, die Singh und Ernst vor einigen Jahren erhoben hatten, dass Chiropraktik gefährlich ist, dass es keine Daten dafür gäbe, dass sie wirksam sei und dass sie gefährliche Nebenwirkungen habe, speziell wenn sie bei Kindern angewendet würde. Die Chiropraktiker hatten den Wissenschaftsjournalisten Singh damals wegen Verleumdung verklagt und recht erhalten. George Lewith hatte dem Gericht die Expertise geliefert und nun seine Analyse auf Kinder ausgedehnt.
Kurz gefasst: Die Intervention wirkt sogar ziemlich stark, etwa eine Standardabweichung war der Effekt groß. Die Kinder schreien kürzer und weniger. Und die Durchforstung der Literatur nach gefährlichen Nebenwirkungen hatte keinen, wortwörtlich: nicht einen, Fall zu Tage gefördert, der von Nebenwirkungen, geschweige denn gefährlichen, berichtet hätte. Die Aufregung war seinerzeit dadurch entstanden, dass eine unqualifizierte Person einer zart gebauten Frau über den Rücken gelaufen ist und ihr dabei das Genick gebrochen hat. Die Presse hatte das ganze dann zu „tödlicher Nebenwirkung chiropraktischer Intervention“ aufgebauscht.
Oh, I almost forgot, you don’t read German? Here is my translation of this revealing text:
“My friend and colleague Geoorge Lewith from Southampton gave a keynote lecture on his review of chiropractic interventions for infant colic. This was prompted by the claim, made by Singh and Ernst a few years ago, that chiropractic was dangerous, that no data existed showing its effectiveness, and that it had dangerous side-effects, particularly for children. The chiropractors had sued the science journalist Singh for libel and won the case. George Lewith had provided the expert report for the court and has now extended his analysis on children.
To put it briefly: the intervention is even very effective; the effect-size is about one standard deviation. The children cry less long and more rarely. And the search of the literature for dangerous side-effects resulted in no – literally: not one – case of side-effects, not to mention dangerous ones. The fuzz had started back then because an unqualified person had walked over the back of a thin woman and had thus broken her neck. The press had subsequently hyped the whole thing to a “deadly side-effect of a chiropractic intervention”. (I am sorry for the clumsy language but the original is even worse.)
Now, isn’t that remarkable? Not only has the truth about the libel case been turned upside down, but also the evidence on chiropractic as a treatment for infant colic seems mysteriously improved; other reviews which might just be a bit more independent and objective come to the following conclusions:
The literature concerning this topic is surprisingly scarce, of poor quality and lack of convincing conclusions. With the present day data on this topic, it is impossible to say whether this kind of treatment has a significant effect.
And what should we make of all this? I don’t know about you, but I conclude that, for some apologists of alternative medicine, the truth is a rather flexible commodity.
Nobody really likes criticism, I suppose. Yet everyone with a functional brain agrees that criticism is a precondition to making progress. So most of us do listen to it, introspect and try to learn a lesson.
Not so in alternative medicine! The last post by Preston Long was a summary of constructive criticism of his own profession; it brought that message home to me much clearer than previous discussions on this blog (probably because it did not directly concern me) and, after some reflection, I realised that apologists of alternative medicine have developed five distinct strategies to avoid progress that otherwise might develop from criticism (alright, these strategies do exist in other fields too, but I think that many of the comments on this blog demonstrate that they are particularly evident in alternative medicine).
We could also call this method ‘The Prince of Wales Technique of Avoiding Progress’ because HRH is famous for making statements ‘ex cathedra’ without ever defending them or facing his critics or allowing others to directly challenge him. When he advocated the Gerson diet for cancer, for instance, Prof Baum challenged him in an open letter asking him to use his influence more wisely. Like with all other criticism directed to him, he decided to ignore it. This strategy is a safe bet for stalling progress and it has the added advantage that it does not require anything other than ignorance.
As it requires some basic understanding of the issues at hand, this method is a little more demanding. You need to look closely at the criticism and subsequently shoot holes in it. If you cannot find any, invent some. For instance, you might state that your critic misquoted the evidence. Very few people will bother to read up the original data, and you are likely to get away even with fairly obvious lies. To beef your response up a bit, pretend that there is plenty of good evidence demonstrating exactly the opposite of what your critic has said. If asked to provide actual references or sources for your claims, don’t listen. An extreme example of the bluff-method is to sue your critic for libel – but be careful, this can backfire in a major way!
A very popular method is to claim that the critic is not actually competent to criticise. The discussion of Long’s post demonstrated that technique in a classic fashion. His detractors argued that he was a failed chiropractor who had an axe to grind and thus had no right to criticise chiropractic (“Preston H Long you are a disgrace to the chiropractic profession…take off your chiropractic hat, you dont deserve to wear it. YOU sir are a shame and a folly!!”). Of course, you need to be a bit simple in order to agree with this type of logic, but lots of people seem to be just that!
Even more popular is the blame-game. It involves arguing that, ok not all is rosy on your side of the fence, but the other side is so, so much worse. Before they dare to challenge you, they should look at their own mess; and while it is not sorted, they must simply shut up. For instance, if the criticism is that chiropractors have put hundreds of their patients into wheelchairs with their neck-manipulations, you must point out that doctors with their nasty drugs are much, much worse (“Long discounts the multitudes that chiropractic has… saved from dangerous drugs and surgery. As far as risks of injury from seeing a chiropractor vs. medicine, all one needs to do is compare malpractice insurance rates to see that insurance carriers rate medicine as an exponentially more dangerous undertaking”). Few people will realise that this is a fallacy and that the risks of any therapy must be seen in relation to its potential benefits.
When criticised, you are understandably annoyed; most people will therefore forgive you calling your critic names which are not normally used in polite circles (“who is this idiot, who wouldnt know the first thing about chiropractic”). Ad hominem attacks are the last resort of apologists of alternative medicine which emerges with depressing regularity when they have run out of rational arguments; they are signs of victories of reason over unreason. In the case of those chiropractors who were unable to stomach Long’s critique, the insults were coming thick and fast. The reason for only very few being visible is quite simple: I often delete the worst excesses of such primitive reactions.
This post was inspired by a shiatsu-practitioner who recently commented on this blog. As I have not yet written a post about shiatsu, I think this might be a good occasion to do so. On one of the websites of the said practitioner – who claimed to have such amazing powers that he “would be locked up or worse“, if he made them public – explains that Shiatsu is a form of natural healing therapy that promotes health through finger pressure along energy meridians or channels – like acupuncture but with no needles and all your clothes on. Shiatsu is a combination of ancient theories of oriental medicine and ‘energy’, with modern knowledge of anatomy and physiology. Shiatsu originated in Japan where it is officially recognised and parents teach their children to treat them. Shiatsu is one of the fastest growing areas of complementary therapy in the UK. Shiatsu is safe and non-invasive. Shiatsu is a holistic therapy which means your whole body is treated. Work on your energy channels promotes well-being at the physical and emotional levels and stimulates your natural self-healing processes. The application of pressure and gentle stretching helps relieve muscle tension, joint stiffness and to realign body structures. Contact with the energy pathways helps to correct imbalance in the functioning of internal organs and to re-balance the effects of emotional disturbance. You don’t have to be ill to enjoy Shiatsu, many people enjoy it simply because it is deeply relaxing.
I also looked up another of his websites and found that he claims to treat the following conditions:
- Anger Management
- Anxiety and Stress
- Back pain
- Bipolar disorder
- Breathing/respiratory problems
- Confidence issues
- Digestive Disorders
- Eating Disorders
- Emotional Issues
- Fears and Phobias
- Irritable bowel syndrome (IBS)
- Joint Pain
- Low energy/Lethargy
- Low Self-Esteem
- ME/Chronic Fatigue Syndrome
- Muscular Tension
- Nausea and sickness
- Panic Attacks
- Sexual problems
- Sinus problems
- Skin conditions
- Sleeping problems
- Social anxiety disorder
- Spiritual Issues
- Weight problems
Impressed by this list, I looked at similar sites and found that such extravagant claims seem more the rule than the exception in the world of shiatsu. Such therapeutic claims came as a big surprise to me: the last time we reviewed the evidence, we had concluded: NO CONVINCING DATA AVAILABLE TO SUGGEST THAT SHIATSU IS EFFECTIVE FOR ANY CONDITION.
But that was 5 years ago; perhaps there have been major advances since? To find out, I did a quick Medline search and – BINGO! – found a recent systematic review entitled “The evidence for Shiatsu: a systematic review of Shiatsu and acupressure“. It was authored by proponents of this therapy and can therefore not be suspected to be riddled with ‘anti-shiatsu bias’ (I just love the give-away title THE EVIDENCE FOR SHIATSU….!). These authors found that “Shiatsu studies comprised 1 RCT, three controlled non-randomised, one within-subjects, one observational and 3 uncontrolled studies investigating mental and physical health issues. Evidence was of insufficient quantity and quality” The only RCT included in their review was not actually a study of shiatsu but of a complex mixture of treatments including shiatsu for back and neck pain. No significant effects compared to standard care were identified in this study.
So, what does that tell us about shiatsu? It clearly tells us that it is an unproven therapy. And what does that say about shiatsu-practitioners who make multiple claims about treating serious conditions? I think I can leave it to my readers to answer this question.
