I am currently studying DD Palmer’s TEXTBOOK OF THE SCIENCE, ART, AND PHILOSOPHY OF CHIROPRACTIC. It is a 1 000 page volume full of ignorance, repetition, allegation, pomp, overstatement and utter nonsense. I strongly advise everyone to stay well clear of it.

However, skimming through this accumulation of flimflam, I was repeatedly reminded of the origin of the anti-vax stance to which so many chiropractors still subscribe. Yes, I did mention this before: Far too many chiropractors believe that vaccinations do not have a positive effect on public health.

In his book, originally published in 1910,  Palmer tried (unsuccessfully, I fear) to explain the basic principles of chiropractic. Most chiropractors would have read at least some of this ‘textbook’. It therefore stands to reason that Palmer’s views still colour those of today’s chiropractors.

Here are a few quotes about immunisation directly from the book:

  • On May 14, 1796, Jenner first committed the crime of vaccination…
  • No person is improved by being poisoned by either smallpox or vaccination.
  • [Vaccination] is the biggest piece of quackery and criminal outrage ever foisted upon any civilized people. Medical ignorance by which criminal outrages are murdering our children all over this country…
  • Vaccination and inoculation are pathological; Chiropractic is physiological.
  • Compulsory vaccination is an outrage and a gross interference with the liberty of the people in a land of freedom.

The question is, where did Palmer get this from? What is the reason for his anti-vax attitude? Reading the book, I get the impression that it might have been based on two main pillars: 1) his amazing ignorance and blinkered view on most things and 2) his deep antipathy of conventional medicine. To show you a little of the latter, here are just two further quotes:

  • It is a pity that the medical profession are possessed of arrogance instead of liberality; that instead of encouraging and fostering advanced ideas, they stifle and discourage advancement; that they only adopt advanced ideas when they are compelled to do so by public opinion.
  • The physician believes in his prescriptions; the pharmacist in the hidden power of drugs – superstitious therapeutics.

To this, I am tempted to add: … and chiropractors believe in the drivel written by DD Palmer over 100 years ago.

The Society of Homeopaths (SoH) is the UK’s professional organisation of lay-homeopaths, therapists who treat patients without having studies medicine. This is what they say about themselves:

Everyone needs a healthcare professional they can trust – one who’s trained to rigorous standards, bound by a strict code of ethics, and subject to independent regulation. That’s what the Society of Homeopaths stands for. We’re the UK’s largest group of professional homeopaths, and the only dedicated register accredited by the Professional Standards Authority, an independent body set up by the government to protect the public.

We work to uphold standards of homeopathic care, support our members in their practices, and help their patients back to good health. We ensure that the letters RSHom are your guarantee of a well-trained, registered and insured professional homeopath.

This sounds fine, but is any of this true? Because of their dubious activities endangering public health, the SoH has attracted my attention many times before (for instance here, here and here). Today, they made national headlines.

It has been reported that Linda Wicks, chair of the Society of Homeopaths (S0H), has shared a series of bizarre petitions claiming that childhood immunisations are unsafe, and calling for The Medicines and Healthcare products Regulatory Agency (MHRH) to be disbanded. Mrs Wicks also posted a petition supporting Andrew Wakefield, the disgraced former doctor who falsely linked the MMR vaccine to autism. It claimed that the scientific establishment’s rejection of his flawed research was ‘the greatest lie ever told’.

Mrs Wicks, a Cornwall-based lay-homeopath and owner of the Linda Wicks Homeopathy Clinic in Truro, has been an adviser to the society for 16 years. She was appointed to the SoH chair in April. She has used her Facebook account to spread ‘anti-vaxx’ propaganda for years. Mrs Wicks must now consider whether such to resign.

Two other members of the board of directors of the SoH are also under pressure to quit. One of them, Francis Treuherz, used his Facebook feed to share a petition describing Mr Wakefield as a ‘hero’ who ought to be ‘honoured’ with the Nobel Peace Prize. In 2016 Treuherz endorsed a campaign urging the then education secretary Justine Greening to ‘STOP vaccination’ of schoolchildren against flu.

The flu petition was shared on Facebook by a third member of the SoH’s board, Maggie Dixon, who owns a homeopathic clinic in Bath. Mrs Dixon works as a member of the ‘team of practitioners’ at Ainsworths, the homeopathic pharmacy boasting of royal warrants from the Queen as well as Prince Charles.

It seems clear to me that the behaviour of Wicks, Treuherz and Dixon endangers public health and is deeply unethical. Considering what the SoH say about themselves (see above), it looks like a bad joke. In my view, it is incompatible with holding an office in a professional organisation of healthcare professionals.

Homeopathy does not have a good name when it comes to advising the public responsibly. Such behaviour is hardly going to improve this situation. The recent call of NHS leaders to stop the accreditation of homeopaths in the UK seems therefore well-justified.

Mrs Wicks meekly apologised yesterday, saying: ‘I regret my association with these petitions and any confusion this may have caused, and I have removed the page which allegedly showed this historic material.’ Confusion? At this stage, I must conclude that she is joking!

The SoH said it was working to improve communication standards ‘with clearer guidelines’. Improve communication standards. Yes, definitely, they are taking the Mikey!

Mr Treuherz and Mrs Dixon did not comment.

So, should they resign?

Would that save the reputation of the SoH?

Is there any reputation to save?


On Twitter, I recently found this remarkable advertisement:

Naturally, it interested me. The implication seemed to be that we can boost our immune system and thus protect ourselves from colds, the flu and other infections by using this supplement. With the flu season approaching, this might be important. On the other hand, the supplement might be unsafe for many other patients. As I had done a bit of research in this area, I needed to know more.

According to the manufacturer’s information sheet, Viracid

  • Provides Support for Immune Challenges
  • Strengthens Immune Function
  • Maintains Normal Inflammatory Balance

The manufacurer furthermore states the following:

Our body’s immune system is a complex and dynamic defense system that comes to our rescue at the first sign of exposure to an outside invader. The dynamic nature of the immune system means that all factors that affect health need to be addressed in order for it to function at peak performance. The immune system is very sensitive to nutrient deficiencies. While vitamin deficiencies can compromise the immune system, consuming immune enhancing nutrients and botanicals can support and strengthen your body’s immune response. Viracid’s synergistic formula significantly boosts immune cell function including antibody response, natural killer (NK) cell activity, thymus hormone secretions, and T-cell activation. Viracid also helps soothe throat irritations and nasal secretions, and maintains normal inflammatory balance by increasing antioxidant levels throughout the body.

This sounds impressive. Viracid could thus play an important role in keeping us healthy. It could also be contra-indicated to lots of patients who suffer from autoimmune and other conditions. In any case, it is worth having a closer look at this dietary supplement. The ingredients of the product include:

  • Vitamin A,
  • Vitamin C,
  • Vitamin B12,
  • Pantothenic Acid,
  • Zinc,
  • L-Lysine Hydrochloride,
  • Echinacea purpurea Extract,
  • Acerola Fruit,
  • Andrographis paniculata,
  • European Elder,
  • Berry Extract,
  • Astragalus membranaceus Root Extract

Next, I conducted several literature searches. Here is what I did NOT find:

  • any clinical trial of Viracid,
  • any indication that its ingredients work synergistically,
  • any proof of Viracid inducing an antibody response,
  • or enhancing natural killer (NK) cell activity,
  • or thymus hormone secretions,
  • or T-cell activation,
  • or soothing throat irritations,
  • or controlling nasal secretions,
  • or maintaining normal inflammatory balance,
  • any mention of contra-indications,
  • any reliable information about the risks of taking Viracid.

There are, of course, two explanations for this void of information. Either I did not search well enough, or the claims that are being made for Viracid by the manufacturer are unsubstantiated and therefore bogus.

Which of the two explanations apply?

Please, someone – preferably the manufacturer – tell me.

“Eating elderberries can help minimise influenza symptoms.” This statement comes from a press release by the University of Sydney. As it turned out, the announcement was not just erroneous but it also had concealed that the in-vitro study that formed the basis for the press-release was part-funded by the very company, Pharmacare, which sells elderberry-based flu remedies.

“This is an appalling misrepresentation of this Pharmacare-funded in-vitro study,” said associate professor Ken Harvey, president of Friends of Science in Medicine. “It was inappropriate and misleading to imply from this study that an extract was ‘proven to fight flu’.” A University of Sydney spokeswoman confirmed Pharmacare was shown a copy of the press release before it was published.

This is an embarrassing turn of events, no doubt. But what about elderberry (Sambucus nigra) and the flu? Is there any evidence?

A systematic review quantified the effects of elderberry supplementation. Supplementation with elderberry was found to substantially reduce upper respiratory symptoms. The quantitative synthesis of the effects yielded a large mean effect size. The authors concluded that these findings present an alternative to antibiotic misuse for upper respiratory symptoms due to viral infections, and a potentially safer alternative to prescription drugs for routine cases of the common cold and influenza.


The alternative to antibiotic misuse can only be the correct use of antibiotics. And, in the case of viral infections such as the flu, this can only be the non-use of antibiotics. My trust in this review, published in a SCAM journal of dubious repute, has instantly dropped to zero.

Perhaps a recent overview recently published in THE MEDICAL LETTER provides a more trustworthy picture:

No large randomized, controlled trials evaluating the effectiveness of elderberry for prevention or treatment of influenza have been conducted to date. Elderberry appears to have some activity against influenza virus strains in vitro. In two small studies (conducted outside the US), adults with influenza A or B virus infection taking elderberry extract reported a shorter duration of symptoms compared to those taking placebo. Consuming uncooked blue or black elderberries can cause nausea and vomiting. The rest of the plant (bark, stems, leaves, and root) contains sambunigrin, which can release cyanide. No data are available on the safety of elderberry use during pregnancy or while breastfeeding. CONCLUSION — Prompt treatment with an antiviral drug such as oseltamivir (Tamiflu, and generics) has been shown to be effective in large randomized, controlled trials in reducing the duration of influenza symptoms, and it may reduce the risk of influenza-related complications. There is no acceptable evidence to date that elderberry is effective for prevention or treatment of influenza and its safety is unclear.

Any take-home messages?


  1. Elderberry supplements are not of proven effectiveness against the flu.
  2. The press officers at universities should be more cautious when writing press-releases.
  3. They should involve the scientists and avoid the sponsors of the research.
  4. In-vitro studies can never tell us anything about clinical effectiveness.
  5. SCAM-journals’ articles must be taken with a pinch of salt.
  6. Consumers are being misled left, right and centre.

Oscillococcinum is by now well-known to readers of this blog, I am sure (see for instance here, here and here). It seems an important topic, not least because the infamous duck-placebo is the world’s best-selling homeopathic remedy. Just how popular it is was recently shown in a survey by the formidable ‘Office for Science and Society’ of the McGill University in Canada.

The researchers surveyed the five biggest pharmacy chains in Quebec: Jean-Coutu, Familiprix, Uniprix, Proxim, and Pharmaprix. For each chain, a sample of 30 pharmacies was chosen by a random number generator.

The calls started with the following script: “I would like to know if you carry a certain homeopathic remedy. It’s called Oscillococcinum, it’s a homeopathic remedy against the flu made by Boiron.” If they did not have it, the investigator asked if this was something they normally carried. He spoke to either a floor clerk or a member of the pharmacy staff behind the counter, depending on who knew the answer.

Out of the 150 pharmacies on the island of Montreal that were called for this investigation, 66% of them reported carrying Oscillococcinum (30% did not, while 4% could not be reached, often because the listed pharmacy had closed). Some chains were more likely to sell the product, with Jean-Coutu and Pharmaprix being the most likely (80% of their stores had it) and Proxim being the least likely (50% of their stores carried it).

The McGill researcher stated that the fact that two-thirds of Montreal-based pharmacies will sell us a pseudo-treatment for the flu that targets adults, children and infants alike is hard to square with the Quebec Order of Pharmacists’ mission statement. They describe said mission as “ensuring the protection of the public”, but how is the public protected when pharmacies are selling them placebo pills? The harm is partly financial: 30 doses of these worthless globules retail for CAD 36. It is also in the false sense of security parents will gain and the delay in proper treatment if needed. And, ultimately, it is in the legitimization of a pseudoscience the founding principle of which is that the more you add water to something (like alcohol), the more powerful it becomes.

I can only full-heartedly agree. One might even add a few more things, for instance that there are other dangers as well:

  1. If pharmacists put commercial gain before medical ethics, we might find it hard to trust this profession.
  2. If people take Oscillococcinum and their condition subsequently disappears (because of the self-limiting nature of the disease), they might believe that homeopathy is effective and consequently use it for much more serious conditions – with grave consequences, I hasten to add.
  3. If consumers thus start trusting homeopaths, they might also fall for some of their abominable health advice, e. g. that about not vaccinating their children.
  4. If a sufficiently large percentage of people believe in the magic of shaken water, our rationality will be undermined and we will encounter phenomena like Brexit or fascists as presidents (sorry, I has to get that off my chest).

It was the very first sentence of the Boiron US website on Oscillococcinum (we have discussed this amazing product before) that caught my attention: “Homeopathy is a therapeutic method that uses diluted substances to relieve symptoms.” I think this is demonstrably wrong.

  • Homeopathy is a therapeutic method that uses mostly the complete absence of an ingredient, and not ‘diluted substances’; specifically, Oscillococcinum is a  C 200 potency ( 1: 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000) which means the likelihood of any substance being present is zero.
  • Homeopathy is, according to Hahnemann, not ‘to relieve symptoms’ but to tackle the root cause of the condition. Hahnemann meant it to be a causal and not a symptomatic treatment (the truth is that it neither relieves symptoms or the root cause of anything).

And then the website continued to puzzle me by stating this: “The active ingredients in homeopathic medicines include diluted plants, animals or minerals that relieve the same symptoms they cause at full strength (i.e., a micro dose of coffee bean helps to relieve nervousness).” This is wrong too, I think:

  • there is no active ingredient in homeopathic medicines,
  • many of the mother tinctures used in homeopathy cause no symptoms whatsoever,
  • a zero dose is not a micro dose,
  • homeopathic coffee does not relieve nervousness better than a placebo.

Now my interest was aroused and I decided to read on. This is what I found under the heading of ‘Frequently Asked Questions’:


Are there clinical studies on Oscillococcinum?

Yes. Two studies, published in peer-reviewed journals, show that Oscillococcinum helps to reduce the severity and shorten the duration of flu-like symptoms.1-2 The most recent study showed that 63 percent of the patients who took Oscillo at the onset of flu-like symptoms showed “clear improvement” or “complete resolution” of their symptoms after 48 hours, vs. 48% with a placebo.2

1Papp R, Schuback G, Beck E, et al. Oscillococcinum in patients with influenza-like syndromes: a placebo-controlled, double-blind evaluation. Br Homeopath J. 1998;87:69-76. 2Ferley JP, Zmirou D, D’Adhemar D, Balducci F. A controlled evaluation of a homeopathic preparation in the treatment of influenza-like syndromes. Br J Clin Pharmacol. 1989;27:329-335.


Now, this is strange!

Why would they cite just two studies when there are several more? Surely they don’t want to be seen to be cherry picking!?!? The current Cochrane review by Mathie RT, Frye J, Fisher P., for instance, included 6 trials!

And what did this review show?

The authors concluded that “There is insufficient good evidence to enable robust conclusions to be made about Oscillococcinum® in the prevention or treatment of influenza and influenza-like illness. Our findings do not rule out the possibility that Oscillococcinum® could have a clinically useful treatment effect but, given the low quality of the eligible studies, the evidence is not compelling. There was no evidence of clinically important harms due to Oscillococcinum®.”

Even though the authors of this Cochrane review are amongst the most ardent homeopathy-promoters on the planet (if not they would not have included this odd 2nd sentence in the above quote), this conclusion does not seem to please Boiron (Christian Boiron seems to have not much time for critical thinking; in a recent, short interview he opined that “Il y a un Ku Klux Klan contre l’homéopathie” THERE IS A KU KLUX KLAN AGAINST HOMEOPATHY).

After studying all this, I ask myself whether Boiron is telling the truth.

What do you think?




I recently came across this article; essentially it claims that, in 1918, chiropractic proved itself to be the method of choice for treating the flu!


Here is a short quote from it:

Chiropractors got fantastic results from influenza patients while those under medical care died like flies all around. Statistics reflect a most amazing, almost miraculous state of affairs. The medical profession was practically helpless with the flu victims but chiropractors seemed able to do no wrong.”

“In Davenport, Iowa, 50 medical doctors treated 4,953 cases, with 274 deaths. In the same city, 150 chiropractors including students and faculty of the Palmer School of Chiropractic, treated 1,635 cases with only one death.”

“In the state of Iowa, medical doctors treated 93,590 patients, with 6,116 deaths – a loss of one patient out of every 15. In the same state, excluding Davenport, 4,735 patients were treated by chiropractors with a loss of only 6 cases – a loss of one patient out of every 789.

“National figures show that 1,142 chiropractors treated 46,394 patients for influenza during 1918, with a loss of 54 patients – one out of every 886.”

“Reports show that in New York City, during the influenza epidemic of 1918, out of every 10,000 cases medically treated, 950 died; and in every 10,000 pneumonia cases medically treated 6,400 died. These figures are exact, for in that city these are reportable diseases.”

“In the same epidemic, under drugless methods, only 25 patients died of influenza out of every 10,000 cases; and only 100 patients died of pneumonia out of every 10,000 cases…”

“In the same epidemic reports show that chiropractors in Oklahoma treated 3,490 cases of influenza with only 7 deaths. But the best part of this is, in Oklahoma there is a clear record showing that chiropractors were called in 233 cases where medical doctors had cared for the patients, and finally gave them up as lost. The chiropractors saved all these lost cases but 25.”


So what does that sort of ‘evidence’ really show?

Does it prove that chiropractic is effective against influenza?


Does it even suggest that chiropractic is effective against influenza?


What then?

I think it shows that some chiropractors (like many homeopaths) are deluded to a point where they are unable to differentiate pseudoscience from science, anecdote from evidence, cause from effect, etc.

In the case you need more explanations, let me re-phrase this section from a previous post:

In the typical epidemiological case/control study, one large group of patients [A] is retrospectively compared to another group [B]. By large, I mean with a sample size of thousands of patients. In our case, group A has been treated by chiropractors, while group B received the treatments available at the time. It is true that several of such reports seemed to suggest that chiropractic works. But this does by no means prove anything; the result might have been due to a range of circumstances, for instance:

  • group A might have been less ill than group B,
  • group A might have been richer and therefore better nourished,
  • group A might have benefitted from better hygiene,
  • group A might have received better care, e. g. hydration,
  • group B might have received treatments that made the situation not better but worse.

Because these are RETROSPECTIVE studies, there is no way to account for these and many other factors that might have influenced the outcome. This means that epidemiological studies of this nature can generate interesting results which, in turn, need testing in properly controlled studies where these confounding factors are adequately controlled for. Without such tests, they are next to worthless.

The fact that some alternative medicine (the authors use the abbreviation ‘CAM’) practitioners recommend against vaccination is well-known and often-documented. Specifically implicated are:

As a result, children consulting homeopaths, naturopaths or chiropractors are less likely to receive vaccines and more likely to get vaccine-preventable diseases. These effects have been noted for several childhood infections but little is known about how child CAM-usage affects influenza vaccination.

A new nationally representative study fills this gap; it analysed ∼9000 children from the Child Complementary and Alternative Medicine File of the 2012 National Health Interview Survey. Adjusting for health services use factors, it examined influenza vaccination odds by ever using major CAM domains: (1) alternative medical systems (AMS; eg, acupuncture); (2) biologically-based therapies, excluding multivitamins/multi-minerals (eg, herbal supplements); (3) multi-vitamins/multi-minerals; (4) manipulative and body-based therapies (MBBT; eg, chiropractic manipulation); and (5) mind-body therapies (eg, yoga).

Influenza vaccination uptake was lower among children ever (versus never) using AMS (33% vs 43%; P = .008) or MBBT (35% vs 43%; P = .002) but higher by using multivitamins/multiminerals (45% vs 39%; P < .001). In multivariate analyses, multivitamin/multimineral use lost significance, but children ever (versus never) using any AMS or MBBT had lower uptake (respective odds ratios: 0.61 [95% confidence interval: 0.44-0.85]; and 0.74 [0.58-0.94]).

The authors concluded that children who have ever used certain CAM domains that may require contact with vaccine-hesitant CAM practitioners are vulnerable to lower annual uptake of influenza vaccination. Opportunity exists for US public health, policy, and medical professionals to improve child health by better engaging parents of children using particular domains of CAM and CAM practitioners advising them.

There is hardly any need to point out that CAM-use is associated with low vaccination-uptake. We have discussed this on my blog ad nauseam – see for instance here, here, here and here. Too many CAM practitioners have an irrational view of vaccinations and advise against their patients against them. Anyone who needs more information might find it right here by searching this blog. Anyone claiming that this is all my exaggeration might look at these papers, for instance, which have nothing to do with me (there are plenty more for those who are willing to conduct a Medline search):

  • Lehrke P, Nuebling M, Hofmann F, Stoessel U. Attitudes of homeopathic physicians towards vaccination. Vaccine. 2001;19:4859–4864. doi: 10.1016/S0264-410X(01)00180-3. [PubMed]
  • Halper J, Berger LR. Naturopaths and childhood immunizations: Heterodoxy among the unorthodox. Pediatrics. 1981;68:407–410. [PubMed]
  • Colley F, Haas M. Attitudes on immunization: A survey of American chiropractors. Journal of Manipulative and Physiological Therapeutics. 1994;17:584–590. [PubMed]

One could, of course, argue about the value of influenza vaccination for kids, but the more important point is that CAM practitioners tend to be against ANY immunisation. And the even bigger point is that many of them issue advice that is against conventional treatments of proven efficacy.

In a previous post I asked the question ‘Alternative medicine for kids: when is it child-abuse?’ I think that evidence like the one reported here renders this question all the more acute.

To honour Hahnemann’s birthday, a National Convention was held yesterday on ‘World Homeopathy Day’ in New Delhi. The theme of the convention is “Enhancing Quality Research in Homeopathy through scientific evidence and rich clinical experiences”. They could have done with this new study of Influenzinum 9C, it seems to me. This is a homeopathic remedy made from the current influenza vaccine. Influenzinum 9C, also known as homeopathic flu nosode. It is claimed to:

  • strengthen the body and increase its resistance to the season’s flu viruses,
  • protect against cold & flu symptoms such as body aches, nausea, chills, fever, headaches, sore throat, coughs, and congestion,
  • enforce the flu vaccine’s action if you have opted for the flu shot,
  • deal with aftereffects of the flu, and
  • alleviate adverse effects of the flu shot.

As these are the claims made by homeopaths (here is but one example of many: “I’ve been using this for over 30 years for my family, and we have never had the flu!”), French researchers have tested whether Influenzinum works. They just published the results of the first study examining the effectiveness of Influenzinum against influenza-like illnesses.

They conducted a retrospective cohort study during winter 2014-2015. After influenza epidemic, a self-assessment questionnaire was offered to patients presenting for a consultation. The primary endpoint was the declaration of an influenza-like illness. The exposed patients (treated by Influenzinum) were matched to two non-exposed patients (untreated) with a propensity score. A conditional logistic model expressed influenza-like illness risk reduction provided by the Influenzinum.

The cohort included 3514 patients recruited from 46 general practitioners. After matching, the treated group (n=2041) and the untreated group (n=482) did not differ on variables collected. Thus Influenzinum preventive therapy did not significantly alter the likelihood of influenza-like illness.

The authors concluded that Influenzinum preventive therapy did not appear effective in preventing influenza-like illness.

This can be no surprise to anyone you knows what ‘C9’ means: it signifies a dilution of 1: 1 000 000 000 000 000 000 (plus 9 times vigorous shaking, of course).

I am sure that some homeopaths will now question whether Influenzinum is truly homeopathic. Is it based on the ‘like cures like’ principle? Before some clever Dick comments ‘THIS SHOWS THAT PROF ERNST HAS NOT GOT A CLUE ABOUT HOMEOPATHY’, please let me point out that it was not I but the homeopaths who insisted in labelling Influenzinum ‘homeopathic’ (see, for instance, here: “Influenzinum Dose is a homoeopathic medicine created by Laboratoire Boiron. Single dose to be consumed in one step. This homoeopathic medicine is generally used as a substitute for the flu vaccine”). AND WHO AM I TO QUESTION THE AUTHORITY OF BOIRON???

Yes, homeopaths are incredibly fond of the notion that homeopathy has been proven to work in numerous population studies of outbreaks of infectious diseases. The argument is bound to come up in any discussion with a ‘well-informed’ homeopathy fan. Therefore, it might be worth addressing it once and for all.

This website offers a fairly good summary of what homeopaths consider to be convincing evidence. It also provides links to the original articles which is valuable for all who want to study them in full detail. I will therefore present the crucial passage here unchanged.


By the end of year 2014, there have been 19 papers published on Epidemiological studies on 7 epidemic diseases (scarlet fever, typhus fever, Cholera, Dengue, meningococcal, influenza and Leptospirosis) in 11 peer-reviewed (beyond year 1893) journals in evidence of Homeopathy including 2 Randomised Controlled Trials.

1. Samuel Hahnemann, “The Cure and prevention of scarlet fever”, Zeitschrift für Praktischen Medizin (Journal of Practical Medicine), 1801, Republished in Lesser Writings. B.Jain Publishing, New Delhi

Preventive use of homeopathy was first applied in 1799 during an epidemic of scarlet fever in Königslütter, Germany, when Dr. Hahnemann prescribed a single dose of Belladonna, as the remedy of the genus epidemicus to susceptible children in the town with more than 95% success rate. In this paper, he also specified how the Belladonna has to be potentised to 1/24,000,000 dilution. His recommended dose of Belladonna was 0.0416 nanograms to be repeated every 72 hrs. This is the first recorded nano dose of medicine used in treatment of any disease [6]. It was another 125 years before Gladys Henry and George Frederick developed a vaccine for scarlet fever in 1924.

The proper use of belladonna has, in most cases, prevented infection. Numerous observations have shown that, by the general use of belladonna, epidemics of scarlet fever have actually been arrested. In those few instances where the use of belladonna was insufficient to prevent infection, the disease has been invariably slight. The Prussian (German Empire) Government ordered the use of the prophylactic during all scarlet fever epidemics

He said, “On board ships – in those confined spaces, filled with mouldy watery vapours, the cholera-miasm finds a favourable element for its multiplication, and grows into an enormously increased brood of those excessively minute, invisible, living creatures, so inimical to human life, of which the contagious matter of the cholera most probably consists millions of those miasmatic animated beings, which, at first developed on the broad marshy banks or the tepid Ganges– on board these ships, I say, this concentrated aggravated miasm kills several of the crew …” [7].
It was another 59 years (1890) before Koch saw these organisms, and later on orthodox medicine gave them the name ‘germs’

A DBRPCT, Oscillococcinum 200c taken twice daily for 5 days significantly increased the rate of cure within two days (n=487, 237 treated and 241 on placebo), absence of symptoms at 48 hours, relative risk estimate significantly favour homeopathy (p=0.048), no pain and no fever (p=0.048), recovery rate (headache, stiffness, articular pain, shivering reduction) at 48 hours better in homeopathy group (p=0.032)

13. Bernard Leary, Cholera 1854 Update, British Homoeopathic Journal, 1994
Sir William Wilde, the well-known allopathic doctor of Dublin, which in his work entitled “Austria and its Institutions”, wrote: “Upon comparing the report of the treatment of Cholera in the Homeopathic hospital testified to by two allopathic medical inspectors appointed by Government with that of the treatment of the same disease in the other hospitals of Vienna during the same period the epidemic of 1836, it appeared that while two-thirds of the cases treated by Dr. Fleischmann the physician of the Homeopathic hospital, recovered, two-thirds of those treated by the ordinary methods in the other hospitals died.”

14. Meningococcinum – its protective effect against meningococcal disease, Homeopathy Links, 2001 (2001)
A total of 65,826 people between the ages of 0–20 were immunised homeopathically to protect against meningococcal disease while 23,532 were not. Over a year period, 4 out of 65,826 protected homeopathically developed meningococcal infection. 20 out of 23,532 not protected developed meningococcal infection. Based on the infection rate in the unprotected group, 58 cases of infection could have been expected in the homeopathically protected group. Instead, there were only four cases of meningococcal infection. Statistical analysis showed that homeopathic immunisation offered 95% protection in the first six months and 91% protection over the year against meningococcal disease. [8]

15. Contribution of homeopathy to the control of an outbreak of dengue epidemic in Macaé, Rio de Janeiro, Brazil in 2007-8 , International Journal of High Dilution Research, 2008
In a campaign ‘Homeopathy campaign against dengue’ by Brazilian Govt, “156,000 doses of homeopathic remedy were freely distributed in April and May 2007 to asymptomatic patients and 129 doses to symptomatic patients treated in outpatient clinics, according to the notion of genus epidemicus . The remedy used was a homeopathic complex against dengue containing Phosphorus 30c, Crotalus horridus 30c and Eupatorium perfoliatum 30c. The incidence of the disease in the first three months of 2008 fell 93% by comparison to the corresponding period in 2007, whereas in the rest of the State of Rio de Janeiro there was an increase of 128%.”

In May 2001, prophylactic use of Eupatorium perfoliatum 30c single dose was given during a dengue outbreak to 40% of residents in the most highly affected neighbourhood which resulted in significant decrease in dengue incidence by 81.5% (p<0.0001) when compared with those neighbourhoods that did not receive homeopathic prophylaxis.

17. Bracho et. al. Application of 200C potency of bacteria for Leptospirosis epidemic control in Cuba 2007-8 (2010)
Conducted by the Finlay Institute, a vaccines producer in Cuba gave 2.308562 million (70% of the target population above the age of 1 year) people in Cuba given two doses (1 dose=5 drops) of 200C potency of a nosode prepared from Leptospirosis bacteria, each (7-9 days apart), for protection against Leptospirosis (fever+jaundice+ inflammation in kidney+enlargement of spleen) with 84% decrease in disease incidence and only 10 reported cases. Dramatic decrease in morbidity within two weeks and zero morbidity of hospitalised patients, non-treated (8.8 millions) area saw an increase in number of cases from 309 cases in 2007 to 376 in 2008 representing a 21% increase. The cost of homeopathic immunization =1/15th of conventional vaccine.

18. Effect of individualized homoeopathic treatment in influenza like illness, Indian Journal of Research in Homeopathy (2013)
A multicenter, single blind, randomized, placebo controlled study to evaluate the effect of homoeopathic medicines in the treatment of Influenza like illness and to compare the efficacy of LM (50 millisimal) potency vis-à-vis centesimal (C) potency. In LM group (n=152), C group (n=147) or placebo (n=148) group. The study revealed the significant effect of individualized homoeopathic treatment in the patients suffering from ILI with no marked difference between LM and Centesimal groups. The medicines which were commonly prescribed were: Arsenic album, Bryonia alba, Rhus tox., Belladonna, Nux vomica, Sepia, Phosphorus, Gelsemium, Sulphur, Natrum mur. and Aconitum napellus. [9]

Whenever I read articles of this nature, I get a little embarrassed. It seems obvious to me that the authors of such reviews have done some ‘research’ and believe strongly in the correctness in what they write. It embarrasses me to see how such people, full of good will, can be so naïve, ignorant and wrong. They clearly fail to understand several crucial issues. To me. this seems like someone such as me lecturing others about car mechanics, quantum physics or kite flying. I have no idea about these subjects, and therefore it would be idiotic to lecture others about them. But homeopaths tend to be different! And this is when my embarrassment quickly turns into anger: articles like the above spread nonsense and misguide people about important issues. THEY ARE DANGEROUS! There is little room for embarrassment and plenty of room for criticism. So, let’s criticise the notions advanced above.

In my recent book, I briefly touched upon epidemics in relation to homeopathy:

Epidemics are outbreaks of disease occurring at the same time in one geographical area and affecting large number of people. In homeopathy, epidemics are important because, in its early days, they seemed to provide evidence for the notion that homeopathy is effective. The results of homeopathic treatment seemed often better than those obtained by conventional means. Today we know that this was not necessarily due to the effects of homeopathy per se, but might have been a false impression caused by bias and confounding.

This tells us the main reason why the much-treasured epidemiological evidence of homeopaths is far from compelling. The review above does not mention these caveats at all. But it is lousy also for a whole host of other reasons, for instance:

  • The text contains several errors (which I find too petty to correct here).
  • The list of studies is the result of cherry-picking the evidence.
  • It confuses what epidemiological studies are; RCTs are certainly not epidemiological studies, for instance.
  • It also omits some of the most important epidemiological studies suggesting homeopathy works.
  • It cites texts that are clearly not epidemiological studies.
  • Several studies are on prevention of illness rather than on treatment.
  • Some studies do not even employ homeopathy at all.

In the typical epidemiological case/control study, one large group of patients [A] is retrospectively compared to another group [B]. By large, I mean with a sample size of thousands of patients. In our case, group A has been treated homeopathically, while group B received the treatments available at the time. It is true that several of such reports seemed to suggest that homeopathy works. But this does by no means prove anything; the result might have been due to a range of circumstances, for instance:

  • group A might have been less ill than group B,
  • group A might have been richer and therefore better nourished,
  • group A might have benefitted from better hygiene in the homeopathic hospital,
  • group A might have received better care, e. g. hydration,
  • group B might have received treatments that made the situation not better but worse.

Because these are RETROSPECTIVE studies, there is no way to account for these and many other factors that might have influenced the outcome. This means that epidemiological studies of this nature can generate interesting results which, in turn, need testing in properly controlled studies where these confounding factors are adequately controlled for. Without such tests, they are next to worthless for recommendations regarding clinical practice.

As it happens, the above author also included two RCT in the review (these are NOT epidemiological studies, as I already mentioned). Let’s have a quick look at them.

The first RCT is flawed for a range of reasons and has been criticised many times before. Even its authors state that “the result cannot be explained given our present state of knowledge, but it calls for further rigorously designed clinical studies.” More importantly, the current Cochrane review of Oscillococcinum, the remedy used in this study, concluded: “There is insufficient good evidence to enable robust conclusions to be made about Oscillococcinum® in the prevention or treatment of influenza and influenza-like illness.”

The second RCT is equally flawed; for instance, its results could be due to the concomitant use of paracetamol, and it seems as though the study was not double blind. The findings of this RCT have so far not been confirmed by an independent replication.

What puzzles me most with these regularly voiced notions about the ‘epidemiological evidence’ for homeopathy is not the deplorable ineptitude of those who promote them, but it is this: do homeopaths really believe that conventional medics and scientists would ignore such evidence, if it were sound or even just encouraging? This assumes that all healthcare professionals (except homeopaths) are corrupt and cynical enough not to follow up leads with the potential to change medicine for ever. It assumes that we would supress knowledge that could save the lives of millions for the sole reason that we are against homeopathy or bribed by ‘BIG PHARMA’.

Surely, this shows more clearly than anything else how deluded homeopaths really are!!!
