When I first saw this press-release, I thought it was a hoax. After all, it came from a most dubious homeopathic source. Then I read it again and was no longer sure.
What do you think?
Here it is in full:
Santa Clara, Cuba, April 3,2020 (Prensa Latina) The homeopathic medicine Prevengho-VIR began to be administered as a measure to confront the Covid-19 in this province of central Cuba.
Dr. Mirtha Rosa Hernandez, head of the Department of the Elderly in Villa Clara, reported that the supply of the preparation began in the Grandparents’ Homes and Elderly Homes of the territory, which has 184,000 people over 60 years old, 23.9 percent of the local universe. The medicine is administered by doctors and nurses of the basic working group where the Grandparents’ Homes and Nursing Homes are located in the 13 municipalities of this province.
This homeopathic medicine comes in a 10-milliliter bottle, and the daily dosage is 5 drops, thrice a day; while on the tenth day a reactivation of the initial dose is performed. It is aimed at preventing the respiratory diseases in this risk group, in addition to other medical conditions, such as dengue.
In the upcoming days it will be extended to the Maternal Homes. It is administered by the doctors and the nurses from the basic work group of the senior homes.
She said, that besides avoiding the new coronavirus the formula is also aimed at preventing respiratory diseases in this risk group, in addition to others such as dengue fever.
This medicine can also be administered to children under 10 years old, pregnant women, nursing mothers, and patients with liver disorders.
Anas berberiae 200
Baptisia tinctora 200
Eupetorium perf 200
Arsenicum Album 200
As I said, I was not sure whether this was for real. Is it possible that even officials are so stupid, brainwashed or gullible to go for homeopathy in such a serious situation?
In an attempt to find out, I did a little search and quickly found that the story has been reported by multiple media. This, for instance, is what the Miami Herald reported:
As scientists around the world speed up clinical trials to find a cure or vaccine for the coronavirus, the Cuban government will begin distributing a homeopathic remedy to the elderly and other vulnerable people to “prevent” the spread of the disease, a top health official said.
Dr. Francisco Durán, national director of Epidemiology at the Ministry of Public Health, said in a press conference on Sunday that “sublingual drops” of the compound PrevengHo-Vir “prevent different diseases such as influenza, the common cold, dengue, and emerging viral infections such as this one.”
On Monday, Durán tried to correct his statements and said that the product “does not prevent contagion” but rather “increases resistance, the body’s defenses against a certain virus.”
Several state media outlets reported that PrevengHo-Vir is already being used in various Cuban provinces to treat the elderly and other groups vulnerable to the coronavirus. There is no internet record of PrevengHo-Vir, other than press reports about the announcement of its distribution in Cuba.
So, it’s not a hoax!
In this case, let me try to predict what will happen next:
- When the pandemic is over, the Cubans will publish mortality rates achieved with their homeopathic prevention [A].
- They will compare them to data from a cohort that did not receive the homeopathic treatment [B].
- Neither of the data-sets will be transparent and nobody will be able to check its reliability.
- The comparison will yield a significant difference in favour of homeopathy.
- The Cubans will use this to market their remedy.
- The world of homeopathy will use it as a proof that homeopathy is effective (it wouldn’t be the first time).
Nothing wrong with that, some will say. Others who understand research methodology will, however, point out that these data are less than convincing.
In such case/control studies, one large group of patients [A] is compared to another group [B]. Group A has been treated homeopathically, while group B received no homeopathy. Any difference in outcome between A and B might be due to a range of circumstances that are unrelated to the homeopathic treatment, for instance:
- group A might have been less ill than group B,
- group A might have been better nourished,
- group A might have benefited from better hygiene,
- group A might have received better care,
- group B might have received treatments that made the situation not better but worse,
- the researchers might have prettified the data to make group A look better.
Such concerns are not totally unfounded; after all, Cuba seems to have a long history of making irresponsible claims for their homeopathic products.
The ‘Corona-Virus Quackery Club’ (CVQC) is enjoying a fast-growing membership. As mentioned in previous posts, it consists of:
Chiropractors have been keen to join since weeks. They have a long tradition of claiming that their ‘adjustments’ boost the immune system, and therefore it was to be expected that they also jump on the corona-bandwagon.
Some chiropractors seem to believe that the corona-virus pandemic is a fine business opportunity or, as one put it, the perfect opportunity to have a heart to heart with patients about their immune and nervous systems! Remember, if germs automatically caused disease, the human race wouldn’t be around to debate the issue. Many forget that Louis Pasteur, the father of the germ theory recanted his belief. On his deathbed he observed, “It’s the soil, not the seed.” In other words, without the right environment, germs can do little harm.
Chiropractors and other health care workers are at greater risk due to patient or client interactions and are encouraged to take extra precautions when it comes to cleaning and disinfecting surfaces and skin or close contact.
“Every chiropractic practice has been touched by coronavirus [fears],” says Bill Esteb, DC, who has created and is circulating a coronavirus and chiropractic guide on how to avoid contracting the virus.
“We wanted to create a tool that chiropractors could use as a conversation springboard. Chiropractors need to remind their patients that germs don’t automatically cause disease. And that ‘catching’ the coronavirus, or anything else, requires a hospitable environment.”
The only way to catch anything, says Esteb, is to become a hospitable host. Flipping the message, Esteb in his coronavirus and chiropractic guide says here is “How to Catch the Coronavirus”:
- Eat a Poor Diet — Make sure your body lacks the vitamins, minerals, enzymes and micronutrients needed to keep itself in good repair.
- Avoid Adequate Rest — Stay up late and use sugar, tobacco, coffee and energy drinks as needed.
- Become Dehydrated — Reduce the effectiveness of your natural defense mechanisms by shunning adequate water.
- Stop Exercising — Reduce the efficiency of your lymphatic system, which requires movement to circulate this important germ-fighting fluid.
- Think Negative Thoughts — Worry that you’ll be a victim. Closely monitor news reports about outbreaks, fearing the advancing pandemic.
- Rarely Wash Your Hands — Use your dirty hands and fingers to rub your eyes, pick your nose or wipe your lips.
- Skip Your Chiropractic Adjustments — Handicap your nervous system, the master system that controls your entire body. Wait until symptoms are clearly present.
“Following these suggestions is the way to become a suitable host for any number of germs or microbes,” Esteb says. “The tongue-in-check approach keeps the subject light. It stimulates more instructive patient conversations. It helps reduce appointment cancellations.
“Most people have an inappropriate fear of germs. And while this poster and patient handout won’t eliminate it, use it to explore the value of ongoing chiropractic care as a preventive strategy.”
The Internet is full with messages of this type. Here is just one example: The best defense for the Corona Virus is to be healthy when you are exposed to the virus. Get adjusted to boost your immune system. Check out this video blog on what you can do to be healthy and prepare your body to fight off the corona virus.
Perhaps the worst excesses can be found on Twitter:
It seems that some people are pushing the notion that Boiron’s homeopathic product
might be helpful for the prevention and/or treatment of the Corona virus infection. To get an idea how implausible this assumption is, read my previous post on the subject.
The website of Boiron, the producer of the product, seems undeterred by plausibility and states the following:
Clinical studies show Boiron Oscillococcinum (Oscillo®) reduces the duration and severity of flu-like symptoms when taken at the onset of symptoms.1-2 Oscillo does not cause drowsiness and has no known or reported drug interactions.
- Temporarily relieves flu-like symptoms such as body aches, headache, fever, chills and fatigue
- Non-drowsy; no drug interactions
- Easy-to-take, quick-dissolving pellets
- For everyone 2 years of age and older
- Make sure your patients always have Oscillococcinum on hand—it works best when taken at the first sign of symptoms. Help your patients feel better before they feel worse.
While this text does not state that Oscillococcinum works for the coronavirus, one could easily read it as implying it, particularly if one also considers this tweet:
Getting sick when travelling can ruin the best of vacations. Take non-drowsy Oscillococcinum the moment you feel body aches, headache, fever, chills or fatigue coming on. http://bit.ly/2BGCmCz
On the Internet we find many much more direct claims. Take this website, for instance:
The commonly indicated Homeopathic remedies for Coronavirus are: –
• Arsenic Album
**However, for best results contact a Qualified Homeopathic doctor so that correct medicines can be prescribed.
And even some politicians promote such irresponsible nonsense.
All the claims about Oscillococcinum have one thing in common: they are not evidence based! Any notion that it might work against the coronavirus is pure fantasy. And the above statement by Boiron is based on two cherry-picked studies. The totality of the evidence, however, does not show that Oscillococcinum is effective. The current Cochrane review says about its effectiveness: 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(®).
The reason, I guess, why this conclusion is not more forthright stating THERE IS NO GOOD EVIDENCE THAT OSCILLOCOCCINUM HAS ANY EFFECT can be found in the list of conflicts of interest of the paper’s authors:
All three review authors are research‐active in the field of homeopathy. They were members of the International Scientific Committee for Homeopathic Investigations (ISCHI), whose membership also included two employees of Boiron (the manufacturers of Oscillococcinum®), and whose committee activities ceased in July 2013. Progress with the Cochrane Review on Oscillococcinum® was presented briefly at ISCHI meetings in 2010 and 2011. The drafting of this Cochrane Review was carried out independently of those communications and of the authors’ other ongoing research activity. ISCHI has not run or sponsored any research on Oscillococcinum®.
Robert T Mathie: Dr Mathie is Research Development Adviser, British Homeopathic Association. He was a member of the International Scientific Committee on Homeopathic Investigations, which ceased its committee activities in July 2013. Joyce Frye: Part of Dr Frye’s salary was supported by a research grant from the Standard Homeopathic Company, paid to her employer, the Center for Integrative Medicine, Department of Family Medicine, University of Maryland, USA. Support ended in June 2013 when Dr Frye resigned from the University of Maryland. Standard Homeopathic Company does not manufacture Oscillococcinum or any similar product, and had no interest in the outcome of the review. Dr Frye received honoraria from the International Scientific Committee on Homeopathic Investigations, which was dissolved in July 2013. Peter Fisher: I am Expert Adviser on Complementary and Alternative Medicine to the National Institute for Health and Clinical Excellence (NICE), which may take an interest in the evidence in this review. I am Editor in Chief of an international, peer‐reviewed journal dedicated to homeopathy. All payments and reimbursements for lectures have been from universities or professional or learned societies. None of these lectures has been dedicated to the subject of this review. Some meetings have been supported by grants from commercial interests, including the manufacturer of the product that is the subject of the review.
So, to be clear: oscillococcinum does not help against the corona or any other virus. Those who claim otherwise are either mistaken, or have a commercial interest, or both.
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?
WHAT DO YOU THINK?
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,
- 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?
- Elderberry supplements are not of proven effectiveness against the flu.
- The press officers at universities should be more cautious when writing press-releases.
- They should involve the scientists and avoid the sponsors of the research.
- In-vitro studies can never tell us anything about clinical effectiveness.
- SCAM-journals’ articles must be taken with a pinch of salt.
- 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:
- If pharmacists put commercial gain before medical ethics, we might find it hard to trust this profession.
- 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.
- 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.
- 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’:
START OF QUOTE
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

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.”
END OF QUOTE
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?
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.
