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 . 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  unless you live in Switzerland . 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 . If things have gone too far already, talk about freedom of choice . Write articles and join blogs talking about what you can do specifically for certain conditions . Encourage your patients to tell their success stories in blogs and other social media forums . It is in most cases utterly useless to engage in any conversation  online with trolls .
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 , they want you to be in control and to be reassured that their treatment continues . 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 .
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 . That was the only time he took two remedies on the same day! 
Find out what you can about your country’s own internet trolls . However, don’t underestimate their effectiveness in swaying popular opinion . There is no denying that their methods are very effective . It doesn’t matter how ludicrous their comments are, don’t go into direct explanation . Learn from the enemy  and repeat a positive message over and over again so it can’t be contorted .
Our colleges should support post-graduate studies featuring marketing and media courses . 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 . Everyone is different – some of us are happy to stand in front of an audience others choose the pen as their sword . The main thing is to do something to save the image of our healing art .
- 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?
- I wonder why this is so – nothing to do with the evidence, I presume?
- Does she refer to the famous ‘Swiss Government report’ which was not by the Swiss Government at all?
- ‘Advertise and educate’ seems to be homeopathic speak for ‘MISLEAD’
- 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).
- Certain conditions??? And I thought homeopaths do not treat conditions, only whole people.
- And forbid them to disclose stories where things did not work out quite so well?
- Very wise! Conversations are fraught with the danger of being found wrong.
- Critics are not critics but ‘trolls’ – makes sense.
- 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.
- Is it not rather the homeopath who wants the treatment to continue – after all, it is her livelihood?
- Ah yes, BIG PHARMA, the last resort of any quack!
- Did she not just praise patient choice as an important virtue?
- Hahnemann was famously cantankerous and argumentative all his life; does that mean that his remedies did not work?
- Homeopaths might need that for your ad hominem attacks.
- Never underestimate the power of truth!!!
- This might show that it is you and not the ‘trolls’ who are ludicrous.
- Particularly as there are no direct explanations for homeopathy.
- First the critics were ‘trolls’, now they have been upgraded to ‘enemy’! Is it really a war?
- You need to repeat it at least regularly so that eventually you believe it yourself.
- Are marketing and media a substitute for evidence?
- Really, first aid? Do homeopaths know what this is? Obviously not!
- But real clinicians, homeopaths call them allopaths, are quite happy simply with effective treatments that help patients to improve.
- And I thought the main thing was to treat patients with the most effective therapies available.
ENOUGH JOKING AND SARCASM!
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
- Acute fevers
- Sore throats
- Mild depression
- 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 ?
A 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:
- The popularity of homeopathy in India could be a myth promoted by apologists.
- 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.
- 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.
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.
If you talk to advocates of homeopathy, you are bound to hear claims that are false or misleading; in fact, you hear them so regularly that you might begin to doubt the truth. For those who have such doubts or are in need of some correct counter-arguments, I have listed here those 12 bogus claims which, in my experience, are most common together with short, suitable, and factual rebuttals.
1) THERE IS NOTHING MYSTERIOUS ABOUT HOMEOPATHY’S MODE OF ACTION, IT WORKS LIKE VACCINATIONS
This argument is used by enthusiasts in response the fact that most homeopathic remedies are too highly diluted to have pharmacological effects. Vaccines are also highly diluted and they are, of course, very effective; therefore, so the bogus notion, there is nothing odd about homeopathy.
The argument is wrong on several levels; the easiest way to refute, I think, it is to point out that vaccines contain measurable amounts of material and lead to measurable changes in the immune system. By contrast, the typical homeopathic remedy (beyond the C12 potency) contains not a single molecule of an active substance and leads to no measurable changes in any system.
2) SIGNIFICANTLY MORE CONTROLLED CLINICAL TRIALS OF HOMEOPATHY ARE POSITIVE THAN NEGATIVE
Several websites of homeopathic organisations make this claim and even provide simple statistics to back it up. Consequently, many homeopathy fans have adopted it.
The statistics they present show that x % of studies are positive, y % are negative and z % are neutral; the whole point is that x is larger than y. The percentage figures may even be correct but they rely on the spurious definitions used: positive = superior to placebo, negative = placebo superior to homeopathy, neutral = no difference between homeopathy and placebo. The latter category was created so that homeopathy comes out trumps.
For all intents and purposes, a study where the experimental treatment is no better than placebo is not a study neutral but a negative result. Thus the negative category in such statistics must be y + z which is, of course, larger than x. In other words, the majority of trials is, in truth, negative.
3) HOMEOPATHY IS SUPPORTED BY NOBEL PRIZE WINNERS
I don’t know of a single Nobel Prize winner who has stated or implied that homeopathy works better than a placebo. Some have tried to find a mechanism of action for homeopathy by doing some basic research and have published theories about it. None of those has been accepted by science.
And if there ever should be a Nobel Prize winner or similarly brilliant person who supports homeopathy, this would merely show that even bright individuals can make mistakes!
4) HOMEOPATHY IS SAFE
Tell that to the child that has just been reported to have died because her parents used homeopathy for an ear infection which (could have been easily treated with antibiotics but) degenerated into a brain abscess with homeopathic therapy. There are many more such tragic cases than I care to remember.
The risks of homeopathy are, of course, minor compared to many conventional treatments, but the risk/benefit balance of homeopathy can never be positive because, unlike those high risk conventional treatments, it has no benefit.
5) HOMEOPATHY DOES NOT LEND ITSELF TO BEING TESTED IN CLINICAL TRIALS
The best way to disprove this argument is to point out that ~ 250 controlled clinical trials are currently available. Every homeopath on the planet boasts about clinical trials – provided they are positive.
6) HOMEOPATHY WORKS VIA QUANTUM ENTANGLEMENT
I do not understand quantum mechanics and, I suspect, neither do the homeopaths who use this argument. But physicists who do understand this subject well are keen to stress that homeopathy cannot be explained in this way.
7) THERE IS NO PROOF THAT HOMEOPATHY DOES NOT WORK
The absence of evidence is not the same as evidence of absence, homeopaths like to exclaim. And they are, of course, correct! However, they forget that, science cannot prove a negative and that, in routine health care, we do not even look for a proof of ineffectiveness. We use those treatments that have a positive proof of effectiveness – everything else is irresponsible.
8) EVEN IF HOMEOPATHY WERE JUST A PLACEBO, IT STILL HELPS PATIENTS AND IS THEREFORE A USEFUL TREATMENT
It is true, of course, that placebo effects can help patients. But it is not true that, for generating a placebo response, we need a placebo. If a clinician administers an effective treatment with compassion, the patient will benefit from a placebo response plus from the specific effects of the treatment. Only giving placebos is therefore tantamount to cheating the patient.
9) THERE IS A WORLDWIDE CONSPIRACY AGAINST HOMEOPATHY
In a way, this argument merely suggests that homeopathic remedies are ineffective in treating paranoia. I have not ever seen a jot of evidence for it – and neither can anyone who uses this claim produce any.
10) YOU NEED TO BE A HOMEOPATH TO BE ABLE TO UNDERSTAND AND ADEQUATELY JUDGE THE VALUE OF HOMEOPATHY
With this notion, homeopaths want to claim that the critics of homeopathy are incompetent. It is like saying that only people who believe in god are allowed to criticise religion. By definition, homeopaths are believers, and therefore they are unlikely to be free of bias when judging the value of homeopathy. Homeopathy is a health technology that must be evaluated like all other health technologies: by independent scientists who know their job.
11) HOMEOPATHY HAS BEEN PROVEN TO WORK FOR LITTLE CHILDREN AND ANIMALS
The argument here is that animals and children cannot possibly respond to placebo. Therefore homeopathy must be more than a placebo.
This notion is twice wrong. Firstly, both animals and children can respond to placebo, if only ‘by proxy’, i.e. via their carers. Secondly, if we consider the totality of the reliable data, we find that neither for children nor for animals is the evidence convincingly positive.
12) HOMEOPATHY HAS BEEN USED VERY SUCCESSFULLY IN MAJOR EPIDEMICS, AND THAT FACT IS PROOF ENOUGH FOR ITS EFFICACY
Yes, there are some rather fascinating historical accounts which homeopaths interpret in this fashion. But if we look a little closer, we invariably find explanations which are much more plausible than the assumption of homeopathy’s effectiveness. Epidemiological observations of this nature can almost never establish cause and effect, and the clinical outcome could have been due to a myriad of confounders unrelated to homeopathy.
On 26/5/2015, I received the email reproduced below. I thought it was interesting, looked up its author (“Shawn is a philosopher and writer educated at York University in Toronto, and the author of two books. He’s also worked with Aboriginal youth in the Northwest Territories of Canada”) and decided to respond by writing a blog-post rather than by answering Alli directly.
Hello Dr. Ernst, this is Shawn Alli from Canada, a blogger and philosopher. I recently finished a critical article on James Randi’s legacy. It gets into everything from ideological science, manipulation, ESP, faith healing, acupuncture and homeopathy.
Let me know what you think about it:
It’s quite long so save it for a rainy day.
So far, the reply from skeptical organizations range from: “I couldn’t read further than the first few paragraphs because I disagree with the claims…” to one word replies: “Petty.”
It’s always nice to know how open-minded skeptical organizations are.
Hopefully you can add a bit more.
Yes, indeed, I can but try to add a bit more!
However, Alli’s actual article is far too long to analyse it here in full. I therefore selected just the bit that I feel most competent commenting on and which is closest to my heart. Below, I re-produce this section of Alli’s article in full. I add my comments at the end (in bold) by inserting numbered responses which refer to the numbers (in round brackets [the square ones refer to Alli’s references]) inserted throughout Alli’s text. Here we go:
Homeopathy & Acupuncture:
A significant part of Randi’s legacy is his war against homeopathy. This is where Randi shines even above mainstream scientists such as Dawkins or Tyson.
Most of his talks ridicule homeopathy as nonsense that doesn’t deserve the distinction of being called a treatment. This is due to the fact that the current scientific method is unable to account for the results of homeopathy (1). In reality, the current scientific method can’t account for the placebo effect as well (2).
But then again, that presents an internal problem as well. The homeopathic community is divided by those who believe it’s a placebo effect and those that believe it’s more than that, advocating the theory of water memory, which mainstream scientists ridicule and vilify (3).
I don’t know what camp is correct (4), but I do know that the homeopathic community shouldn’t follow the lead of mainstream scientists and downplay the placebo effect as, it’s just a placebo (5).
Remember, the placebo effect is downplayed because the current scientific method is unable to account for the phenomenon (3, 5). It’s a wondrous and real effect, regardless of the ridicule and vilification (6) that’s attached to it.
While homeopathy isn’t suitable as a treatment for severe or acute medical conditions, it’s an acceptable treatment for minor, moderate or chronic ones (7). Personally, I’ve never tried homeopathic treatments. But I would never tell individuals not to consider it. To each their own, as long as it’s within universal ethics (8).
A homeopathic community in Greece attempts to conduct an experiment demonstrating a biological effect using homeopathic medicine and win Randi’s million dollar challenge. George Vithoulkas and his team spend years creating the protocol of the study, only to be told by Randi to redo it from scratch.  (9) I recommend readers take a look at:
Randi’s war against homeopathy is an ideological one (10). He’ll never change his mind despite positive results in and out of the lab (11). This is the epitome of dogmatic ideological thinking (12).
The same is true for acupuncture (13). In his NECSS 2012 talk Randi says:
Harvard Medical School is now offering an advanced course for physicians in acupuncture, which has been tested endlessly for centuries and it does not work in any way. And believe me, I know what I’m talking about. 
Acupuncture is somewhat of a grey area for mainstream scientists and the current scientific method. One ideological theory states that acupuncture operates on principles of non-physical energy in the human body and relieving pressure on specific meridians. The current scientific method is unable to account for non-physical human energy and meridians.
A mainstream scientific theory of acupuncture is one of neurophysiology, whereby acupuncture works by affecting the release of neurotransmitters. I don’t know which theory is correct; but I do know that those who do try acupuncture usually feel better (14).
In regards to the peer-reviewed literature, I believe (15) that there’s a publication bias against acupuncture being seen as a viable treatment for minor, moderate or chronic conditions. A few peer-reviewed articles support the use of acupuncture for various conditions:
Eight sessions of weekly group acupuncture compared with group oral care education provide significantly better relief of symptoms in patients suffering from chronic radiation-induced xerostomia. 
It is concluded that this study showed highly positive effects on pain and function through the collaborative treatment of acupuncture and motion style in aLBP [acute lower back pain] patients. 
Given the limited efficacy of antidepressant treatment…the present study provides evidence in supporting the viewpoint that acupuncture is an effective and safe alternative treatment for depressive disorders, and could be considered an alternative option especially for patients with MDD [major depressive disorder] and PSD [post-stroke depression], although evidence for its effects in augmenting antidepressant agents remains controversial. 
In conclusion: We find that acupuncture significantly relieves hot flashes and sleep disturbances in women treated for breast cancer. The effect was seen in the therapy period and at least 12 weeks after acupuncture treatment ceased. The effect was not correlated with increased levels of plasma estradiol. The current study showed no side effects of acupuncture. These results indicate that acupuncture can be used as an effective treatment of menopausal discomfort. 
In conclusion, the present study demonstrates, in rats, that EA [electroacupuncture] significantly attenuates bone cancer induced hyperalgesia, which, at least in part, is mediated by EA suppression of IL-1…expression. 
In animal model of focal cerebral ischemia, BBA [Baihui (GV20)-based Scalp acupuncture] could improve IV [infarct volume] and NFS [neurological function score]. Although some factors such as study quality and possible publication bias may undermine the validity of positive findings, BBA may have potential neuroprotective role in experimental stroke. 
In conclusion, this randomized sham-controlled study suggests that electroacupuncture at acupoints including Zusanli, Sanyinjiao, Hegu, and Zhigou is more effective than no acupuncture and sham acupuncture in stimulating early return of bowel function and reducing postoperative analgesic requirements after laparoscopic colorectal surgery. Electroacupuncture is also more effective than no acupuncture in reducing the duration of hospital stay. 
In conclusion, we found acupuncture to be superior to both no acupuncture control and sham acupuncture for the treatment of chronic pain…Our results from individual patient data meta-analyses of nearly 18000 randomized patients in high-quality RCTs [randomized controlled trials] provide the most robust evidence to date that acupuncture is a reasonable referral option for patients with chronic pain. 
While Randi and many other mainstream scientists will argue (16) that the above claims are the result of ideological science and cherry picking, in reality, they’re the result of good science going up against dogmatic (17) and profit-driven (17) ideological (17) science.
Yes, the alternative medicine industry is now a billion dollar industry. But the global pharmaceutical medical industry is worth hundreds of trillions of dollars. And without its patients (who need to be in a constant state of ill health), it can’t survive (18).
Individuals who have minor, moderate, or chronic medical conditions don’t want to be part of the hostile debate between alternative medicine vs. pharmaceutical medical science (19). They just want to get better and move on with their life. The constant war that mainstream scientists wage against alternative medicine is only hurting the people they’re supposed to be helping (20).
Yes, the ideologies (21) are incompatible. Yes, there are no accepted scientific theories for such treatments. Yes, it defies what mainstream scientists currently “know” about the human body (22).
It would be impressive if a peace treaty can exist between both sides, where both don’t agree, but respect each other enough to put aside their pride and help patients to regain their health (23).
END OF ALLI’S TEXT
And here are my numbered comments:
(1) This is not how I understand Randi’s position. Randi makes a powerful point about the fact that the assumptions of homeopathy are not plausible, which is entirely correct – so much so that even some leading homeopaths admit that this is true.
(2) This is definitely not correct; the placebo effect has been studied in much detail, and we can certainly ‘account’ for it.
(3) In my 40 years of researching homeopathy and talking to homeopaths, I have not met any homeopaths who “believe it’s a placebo effect”.
(4) There is no ‘placebo camp’ amongst homeopaths; so this is not a basis for an argument; it’s a fallacy.
(5) They very definitely are mainstream scientists, like F Benedetti, who research the placebo effect and they certainly do not ‘downplay’ it. (What many people fail to understand is that, in placebo-controlled trials, one aims at controlling the placebo effect; to a research-naïve person, this may indeed LOOK LIKE downplaying it. But this impression is wrong and reflects merely a lack of understanding.)
(6) No serious scientist attaches ‘ridicule and vilification’ to it.
(7) Who says so? I know only homeopaths who hold this opinion; and it is not evidence-based.
(8) Ethics demand that patients require the best available treatment; homeopathy does not fall into this category.
(9) At one stage (more than 10 years ago), I was involved in the design of this test. My recollection of it is not in line with the report that is linked here.
(10) So far, we have seen no evidence for this statement.
(11) Which ones? No examples are provided.
(12) Yet another statement without evidence – potentially libellous.
(13) Conclusion before any evidence; sign for a closed mind?
(14) This outcome could be entirely unrelated to acupuncture, as anyone who has a minimum of health care knowledge should know.
(15) We are not concerned with beliefs, we concerned with facts here, aren’t we ?
(16) But did they argue this? Where is the evidence to support this statement?
(17) Non-evidence-based accusations.
(18) Classic fallacy.
(19) The debate is not between alt med and ‘pharmaceutical science’, it is between those who insist on treatments which demonstrably generate more good than harm, and those who want alt med regardless of any such considerations.
(20) Warning consumers of treatments which fail to fulfil the above criterion is, in my view, an ethical duty which can save much money and many lives.
(21) Yes, alt med is clearly ideology-driven; by contrast conventional medicine is not (if it were, Alli would have explained what ideology it is precisely). Conventional medicine changes all the time, sometimes even faster than we can cope with, and is mainly orientated on evidence which is not an ideology. Alt med hardly changes or progresses at all; for the most part, its ideology is that of a cult celebrating anti-science and obsolete traditions.
(22) Overt contradiction to what Alli just stated about acupuncture.
(23) To me, this seems rather nonsensical and a hindrance to progress.
In summary, I feel that Alli argues his corner very poorly. He makes statements without supporting evidence, issues lots of opinion without providing the facts (occasionally even hiding them), falls victim of logical fallacies, and demonstrates an embarrassing lack of knowledge and common sense. Most crucially, the text seems bar of any critical analysis; to me, it seems like a bonanza of unreason.
To save Alli the embarrassment of arguing that I am biased or don’t know what I am talking about, I’d like to declare the following: I am not paid by ‘Big Pharma’ or anyone else, I am not aware of having any other conflicts of interest, I have probably published more research on alt med (some of it with positive conclusions !!!) than anyone else on the planet, my research was funded mostly by organisations/donors who were in favour of alt med, and I have no reason whatsoever to defend Randi (I only met him personally once). My main motivation for responding to Alli’s invitation to comment on his bizarre article is that I have fun exposing ‘alt med nonsense’ and believe it is a task worth doing.
The other day, I received a request from THE GUARDIAN: could I write a piece on homeopathy in relation to the Australian report which had just come out; they gave me ~700 words and all of 3 hours to do it. I had an extremely busy day, but accepted the challenge nevertheless.
My article was published the next day and the ‘headliner’ at THE GUARDIAN had elected to call it There is no scientific case for homeopathy: the debate is over.
What followed was a flurry of debate – well over 2200 comments – which was more than a little ironic, considering the headline.
Essentially, my article had repeated the well-rehearsed arguments which have so often been made on this blog and elsewhere:
• Our trials failed to show that homeopathy is more than a placebo.
• Our reviews demonstrated that the most reliable of the 230 or so trials of homeopathy ever published are also not positive.
• Studies with animals confirmed the results obtained on humans.
• Surveys and case reports suggested that homeopathy can be dangerous.
• The claims made by homeopaths to cure conditions like cancer, asthma or even Ebola were bogus.
• The promotion of homeopathy is not ethical.
The comments that followed were mixed, of course; those that disagreed with me used a range of counter-arguments; in no specific order, these were the following:
- For several reasons, I cannot be trusted.
- I even once stated that I have treated my wife homeopathically.
- The Australian report was neither thorough nor reliable.
- The Australian expert panel were bought by Big Pharma.
- Homeopathic treatment must be individualised and can therefore not be tested in RCTs.
- Just because we don’t understand how homeopathy works, we should not conclude that it is ineffective.
- 200 years of positive experience with homeopathy clearly prove that it works.
- The huge popularity of homeopathy worldwide demonstrated its effectiveness.
- The fact that some very clever people support homeopathy shows that it works.
- Homeopathy works in animals and little children, therefore it cannot be just a placebo.
- The Queen and my aunt Doris use homeopathy.
- Placebos work.
- Patients must be able to choose; patient choice is an important principle in all health care.
- There’s more to evidence than just RCTs.
- Homeopathy works like vaccines.
With such an abundance of counter-arguments, the debate is clearly NOT over! Or is it? Let’s see how solid the arguments really are.
1) I cannot be trusted
Ad hominem attacks are no arguments at all; they are merely a sign that the person using them has no real arguments left.
2) I treated my wife homeopathically
This is true. At one stage in my life, I treated anyone who couldn’t run fast enough to escape me with homeopathy. What does that show? It simply shows that I can make mistakes too.
3) The Australian report was flawed
Perhaps it was not entirely faultless (no report ever is), but it certainly was rigorous – more so than any previous document in the entire history of homeopathy. If it excluded certain types of evidence, like the observational studies (which are so much loved by homeopaths), it did so because such data are wide open to bias.
4) The panel was not independent
Yes, it was! It even included a homeopath. The Australian National Health and Medical Research Council is internationally highly respected, and to defame it without evidence is, in a way, just another ad hominem attack.
5) Homeopathy must be individualised
This is a half-truth: classical homeopathy is mostly individualised, but lots of homeopathic prescribing is not individualised. And in any case, we have recently seen how totally unconvincing the results of strictly individualised trials of homeopathy are. This argument turns out to be a red herring.
6) We currently don’t understand how homeopathy works
What we do understand perfectly well, however, is the fact that no explanation exists which would not require throwing over board big chunks of the laws of nature. But even if we accepted that the mode of action is unknown, this would not change the lack of homeopathy’s clinical effectiveness. Lots of treatments work without us understanding how.
7) Experience shows it works
Experience is a very unreliable indicator of effectiveness; there are simply far too many confounders such as placebo effects, regression towards the mean or natural history of the disease. This is why we need evidence to be sure, and historically medicine finally started making progress when this lesson had been learnt.
8) The amazing popularity of homeopathy is proof of its effectiveness
This is the ‘argumentum ad populum’ fallacy. Think of the popularity of blood-letting to see how wrong this argument can be.
9) Homeopathy is backed by some very clever people
So what? Clever people are not always correct – look at me (just joking!)
10) Homeopathy works in animals and little children which proves that it is more than a placebo
First, animals and children do also show placebo-responses.
Second, the animal owner/parent might respond to placebo and thus mimic a placebo-response in the patient.
Third, the evidence for homeopathy is not positive neither in animals nor in children.
11) The Queen swears by homeopathy
Yes, so much so that, as soon as she is really ill, she makes use of what the very best of conventional medicine has to offer.
12) Placebos work
For sure! But that does not mean that we should prescribe placebos. If an effective treatment is given with compassion and empathy, the patient will also profit from a placebo effect – in addition to the effect of the treatment. Merely administering placebos means withholding the latter and is thus not in the best interest of the patient.
13) Patient choice
Yes, patient choice is important. However, it only applies to the choice between treatments that are demonstrably effective – if not choice becomes arbitrariness.
14) Evidence is more than just RCTs
True, there are many study designs other than RCTs. They all have their place in research – but when the research question is to test whether a treatment is effective beyond placebo, they are all open to different types of bias. The one that minimises bias best and thus produces more reliable findings than any other study design is the placebo-controlled, double-blind RCT.
15) Homeopathy works like vaccines
No! The ‘like cures like principle’ appears to be similar to the principles of vaccination, but this appearance is misleading. Vaccines contain small amounts of active material, while the typical homeopathic remedy doesn’t. Vaccines use the substance that causes the illness, e. g. (parts of) a virus, while homeopathy doesn’t.
So, is there still a debate? Obviously there is – the Guardian headliner was wrong – but it is a debate without reasonable arguments. And in the public domain, the debate is dominated by enthusiasts who endlessly repeat nonsensical notions which have been shown to be wrong over and over again.
In a nutshell:
Yes, there continues to be a debate.
No, there is no reasonable debate.
I would have never thought that someone would be able to identify the author of the text I quoted in the previous post:
It is known that not just novel therapies but also traditional ones, such as homeopathy, suffer opposition and rejection by some doctors without having ever been subjected to serious tests. The doctor is in charge of medical treatment; he is thus responsible foremost for making sure all knowledge and all methods are employed for the benefit of public health…I ask the medical profession to consider even previously excluded therapies with an open mind. It is necessary that an unbiased evaluation takes place, not just of the theories but also of the clinical effectiveness of alternative medicine.
More often than once has science, when it relied on theory alone, arrived at verdicts which later had to be overturned – frequently this occurred only after long periods of time, after progress had been hindered and most acclaimed pioneers had suffered serious injustice. I do not need to remind you of the doctor who, more than 100 years ago, in fighting puerperal fever, discovered sepsis and asepsis but was laughed at and ousted by his colleagues throughout his lifetime. Yet nobody would today deny that this knowledge is most relevant to medicine and that it belongs to the basis of medicine. Insightful doctors, some of whom famous, have, during the recent years, spoken openly about the crisis in medicine and the dead end that health care has maneuvered itself into. It seems obvious that the solution is going in directions which embrace nature. Hardly any other form of science is so tightly bound to nature as is the science occupied with healing living creatures. The demand for holism is getting stronger and stronger, a general demand which has already been fruitful on the political level. For medicine, the challenge is to treat more than previously by influencing the whole organism when we aim to heal a diseased organ.
It is from the opening speech by Rudolf Hess on the occasion of the WORLD CONFERENCE ON HOMEOPATHY 1937, in Berlin. Hess, at the time Hitler’s deputy, was not the only Nazi-leader. I knew of the opening speech because, a few years ago, DER SPIEGEL published a theme issue on homeopathy, and they published a photo of the opening ceremony of this meeting. It shows many men in SS-uniform and, in the first row of the auditorium, we see Hess (as well as Himmler) ready to spring into action.
Hess in particular was besotted with alternative medicine which the Nazis elected to call NEUE DEUTSCHE HEILKUNDE. Somewhat to the dismay of today’s alternative medicine enthusiasts, I have repeatedly published on this aspect of alternative medicine’s past, and it also is an important part of my new book A SCIENTIST IN WONDERLAND which the lucky winner (my congratulations!) of my little competition to identify the author has won. The abstract of an 2001 article explains this history succinctly:
The aim of this article is to discuss complementary/alternative medicine (CAM) in the Third Reich. Based on a general movement towards all things natural, a powerful trend towards natural ways of healing had developed in the 19(th)century. By 1930 this had led to a situation where roughly as many lay practitioners of CAM existed in Germany as doctors. To re-unify German medicine under the banner of ‘Neue Deutsche Heilkunde’, the Nazi officials created the ‘Heilpraktiker’ – a profession which was meant to become extinct within one generation. The ‘flag ship’ of the ‘Neue Deutsche Heilkunde’ was the ‘Rudolf Hess Krankenhaus’ in Dresden. It represented a full integration of CAM and orthodox medicine. An example of systematic research into CAM is the Nazi government’s project to validate homoeopathy. Even though the data are now lost, the results of this research seem to have been negative. Even though there are some striking similarities between today’s CAM and yesterday’s ‘Neue Deutsche Heilkunde’ there are important differences. Most importantly, perhaps, today’s CAM is concerned with the welfare of the individual, whereas the ‘Neue Deutsche Heilkunde’ was aimed at ensuring the dominance of the Aryan race.
One fascinating aspect of this past is the fact that the NEUE DEUTSCHE HEILKUNDE was de facto the invention of what we today call ‘integrated medicine’. Then it was more like a ‘shot-gun marriage’, while today it seems to be driven more by political correctness and sloppy thinking. It did not work 70 years ago for the same reason that it will fail today: the integration of bogus (non-evidence based) treatments into conventional medicine must inevitably render health care not better but worse!
One does not need to be a rocket scientist to understand that, and Hess as well as other proponents of alternative medicine of his time had certainly got the idea. So they initiated the largest ever series of scientific tests of homeopathy. This research program was not just left to the homeopaths, who never had a reputation of being either rigorous or unbiased, but some of the best scientists of the era were recruited for it. The results vanished in the hands of the homeopaths during the turmoil of the war. But one eye-witness report of a homeopaths, Fritz Donner, makes it very clear: as it turned out, there was not a jot of evidence in favour of homeopathy.
And this, I think, is the other fascinating aspect of the story: homeopaths did not give up their plight to popularise homeopathy. On the contrary, they re-doubled their efforts to fool us all and to convince us with dodgy results (see recent posts on this blog) that homeopathy somehow does defy the laws of nature and is, in effect, very effective for all sorts of diseases.
My readers suggested all sorts of potential authors for the Hess speech; and they are right! It could have been written by any proponent of alternative medicine. This fact is amusing and depressing at the same time. Amusing because it discloses the lack of new ideas and arguments (even the same fallacies are being used). Depressing because it suggests that progress in alternative medicine is almost totally absent.
Moxibustion is an ancient variation of acupuncture using moxa made from dried mugwort (Artemisia argyi). It has long played an important role in the traditional heath care systems of China and other Asian countries. More recently, it has become popular also in the West. Practitioners use moxa sticks indirectly to warm acupuncture needles, or burn it close to the patient’s skin. Essentially, moxibustion is a treatment where acupuncture points are stimulated mainly or exclusively by the heat of burning moxa.
Because of moxibustion’s long history of usage and the fact that it is employed in many countries for a very wide range of conditions, some might argue that it has stood the ‘test of time’ and should be considered to be a well-established therapy. More critical thinkers would, however, point out that this is not an argument but a classical fallacy.
My team at Exeter regularly had research fellows from Korea and other Asian countries, and we managed to develop a truly productive cooperation. It enabled us to conduct systematic reviews including the Asian literature – and this is how we got involved in an unusual amount of research into moxibustion which, after all, is a fairly exotic alternative therapy. In 2010, we began a series of systematic reviews of moxibustion.
One of the first such articles included 9 RCTs testing the effectiveness of this treatment for stroke rehabilitation. Three RCTs reported favorable effects of moxibustion plus standard care on motor function versus standard care alone Three randomized clinical trials compared the effects of moxibustion on activities of daily living alone but failed to show favorable effects of moxibustion.
Also in 2010, our systematic review of RCTs of moxibustion as a treatment of ulcerative colitis (UC) concluded that current evidence is insufficient to show that moxibustion is an effective treatment of UC. Most of included trials had high risk of bias. More rigorous studies seem warranted.
Our (2010) systematic review od RCTs of moxibustion as a therapy in cancer care found that the evidence was limited to suggest moxibustion is an effective supportive cancer care in nausea and vomiting. However, all studies had a high risk of bias so effectively there was not enough evidence to draw any conclusion.
Our (2010) systematic review of RCTs of moxibustion for treating hypertension concluded that there was insufficient evidence to suggest that moxibustion is an effective treatment for hypertension.
Our (2010) systematic review of RCTs of moxibustion for constipation concluded as follows: Given that the methodological quality of all RCTs was poor, the results from the present review are insufficient to suggest that moxibustion is an effective treatment for constipation. More rigorous studies are warranted.
Our (2010) systematic review found few RCTs were available that test the effectiveness of moxibustion in the management of pain, and most of the existing trials had a high risk of bias. Therefore, more rigorous studies are required before the effectiveness of moxibustion for the treatment of pain can be determined.
Our (2011) systematic review of 14 RCTs of moxibustion for rheumatic conditions failed to provide conclusive evidence for the effectiveness of moxibustion compared with drug therapy in rheumatic conditions.
The, so far, last article in this series has only just been published. The purpose of this systematic review was to assess the efficacy of moxibustion as a treatment of chemotherapy-induced leukopenia. Twelve databases were searched from their inception through June 2014, without a language restriction. Randomized clinical trials (RCTs) were included, if moxibustion was used as the sole treatment or as a part of a combination therapy with conventional drugs for leukopenia induced by chemotherapy. Cochrane criteria were used to assess the risk of bias.
Six RCTs with a total of 681 patients met our inclusion criteria. All of the included RCTs were associated with a high risk of bias. The trials included patients with various types of cancer receiving ongoing chemotherapy or after chemotherapy. The results of two RCTs suggested the effectiveness of moxibustion combined with chemotherapy vs. chemotherapy alone. In four RCTs, moxibustion was more effective than conventional drug therapy. Six RCTs showed that moxibustion was more effective than various types of control interventions in increasing white blood cell counts.
Our conclusion: there is low level of evidence based on these six trials that demonstrates the superiority of moxibustion over drug therapies in the treatment of chemotherapy-induced leukopenia. However, the number of trials, the total sample size, and the methodological quality are too low to draw firm conclusions. Future RCTs appear to be warranted.
Was all this research for nothing?
I know many people who would think so. However, I disagree. If nothing else, these articles demonstrated several facts quite clearly:
- There is quite a bit of research even on the most exotic alternative therapy; sometimes one needs to look hard and include languages other than English.
- Studies from China and other Asian counties very rarely report negative results; this fact casts a dark shadow on the credibility of such data.
- The poor quality of trials in most areas of alternative medicine is lamentable and must be stimulus for researchers in this field to improve their act.
- Authors of systematic reviews must resist the temptation to draw positive conclusions based on flawed primary data.
- Moxibustion is a perfect example for demonstrating that the ‘test of time’ is no substitute for evidence.
- As for moxibustion, it cannot currently be considered an evidence-based treatment for any condition.
Naturopathy can be defined as ‘an eclectic system of health care that uses elements of complementary and conventional medicine to support and enhance self-healing processes’. This basically means that naturopaths employ treatments based on those therapeutic options that are seen as natural, e. g. herbs, water, exercise, diet, fresh air, heat and cold – but occasionally also acupuncture, homeopathy and manual therapies. If you are tempted to see a naturopath, you might want to consider the following 7 points:
- In many countries, naturopathy is not a protected title; this means your naturopaths may have some training but this is not obligatory. Some medical doctors also practice naturopathy, and in some countries there are ‘doctors of naturopathy’ (these practitioners tend to see themselves as primary care physicians but they have not been to medical school).
- Naturopathy is steeped in the obsolete concept of vitalism which has been described as the belief that “living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things.”
- While there is some evidence to suggest that some of the treatments used by naturopaths are effective for treating some conditions, this is by no means the case for all of the treatments in question.
- Naturopathy is implicitly based on the assumption that natural means safe. This notion is clearly wrong and misleading: not all the treatments used by naturopaths are strictly speaking natural, and very few are totally free of risks.
- Many naturopaths advise their patients against conventional treatments such as vaccines or antibiotics.
- Naturopaths tend to believe they can cure all or most diseases. Consequently many of the therapeutic claims for naturopathy found on the Internet and elsewhere are dangerously over-stated.
- The direct risks of naturopathy depend, of course, on the modality used; some of them can be considerable. The indirect risks of naturopathy can be even more serious and are mostly due to naturopathic treatments replacing more effective conventional therapies in cases of severe illness.
Acupuncture seems to be as popular as never before – many conventional pain clinics now employ acupuncturists, for instance. It is probably true to say that acupuncture is one of the best-known types of all alternative therapies. Yet, experts are still divided in their views about this treatment – some proclaim that acupuncture is the best thing since sliced bread, while others insist that it is no more than a theatrical placebo. Consumers, I imagine, are often left helpless in the middle of these debates. Here are 7 important bits of factual information that might help you make up your mind, in case you are tempted to try acupuncture.
- Acupuncture is ancient; some enthusiast thus claim that it has ‘stood the test of time’, i. e. that its long history proves its efficacy and safety beyond reasonable doubt and certainly more conclusively than any scientific test. Whenever you hear such arguments, remind yourself that the ‘argumentum ad traditionem’ is nothing but a classic fallacy. A long history of usage proves very little – think of how long blood letting was used, even though it killed millions.
- We often think of acupuncture as being one single treatment, but there are many different forms of this therapy. According to believers in acupuncture, acupuncture points can be stimulated not just by inserting needles (the most common way) but also with heat, electrical currents, ultrasound, pressure, etc. Then there is body acupuncture, ear acupuncture and even tongue acupuncture. Finally, some clinicians employ the traditional Chinese approach based on the assumption that two life forces are out of balance and need to be re-balanced, while so-called ‘Western’ acupuncturists adhere to the concepts of conventional medicine and claim that acupuncture works via scientifically explainable mechanisms that are unrelated to ancient Chinese philosophies.
- Traditional Chinese acupuncturists have not normally studied medicine and base their practice on the Taoist philosophy of the balance between yin and yang which has no basis in science. This explains why acupuncture is seen by traditional acupuncturists as a ‘cure all’ . In contrast, medical acupuncturists tend to cite neurophysiological explanations as to how acupuncture might work. However, it is important to note that, even though they may appear plausible, these explanations are currently just theories and constitute no proof for the validity of acupuncture as a medical intervention.
- The therapeutic claims made for acupuncture are legion. According to the traditional view, acupuncture is useful for virtually every condition affecting mankind; according to the more modern view, it is effective for a relatively small range of conditions only. On closer examination, the vast majority of these claims can be disclosed to be based on either no or very flimsy evidence. Once we examine the data from reliable clinical trials (today several thousand studies of acupuncture are available – see below), we realise that acupuncture is associated with a powerful placebo effect, and that it works better than a placebo only for very few (some say for no) conditions.
- The interpretation of the trial evidence is far from straight forward: most of the clinical trials of acupuncture originate from China, and several investigations have shown that very close to 100% of them are positive. This means that the results of these studies have to be taken with more than a small pinch of salt. In order to control for patient-expectations, clinical trials can be done with sham needles which do not penetrate the skin but collapse like miniature stage-daggers. This method does, however, not control for acupuncturists’ expectations; blinding of the therapists is difficult and therefore truly double (patient and therapist)-blind trials of acupuncture do hardly exist. This means that even the most rigorous studies of acupuncture are usually burdened with residual bias.
- Few acupuncturists warn their patients of possible adverse effects; this may be because the side-effects of acupuncture (they occur in about 10% of all patients) are mostly mild. However, it is important to know that very serious complications of acupuncture are on record as well: acupuncture needles can injure vital organs like the lungs or the heart, and they can introduce infections into the body, e. g. hepatitis. About 100 fatalities after acupuncture have been reported in the medical literature – a figure which, due to lack of a monitoring system, may disclose just the tip of an iceberg.
- Given that, for the vast majority of conditions, there is no good evidence that acupuncture works beyond a placebo response, and that acupuncture is associated with finite risks, it seems to follow that, in most situations, the risk/benefit balance for acupuncture fails to be convincingly positive.
