Today is WORLD ASTHMA DAY, a good opportunity perhaps to revisit a few of our own evaluations of so-called alternative medicine (SCAM) for asthma. Here are the abstracts of some of our systematic reviews on the subject:
Objective: The objective of this systematic review was to assess the effectiveness of yoga as a treatment option for asthma.
Method: Seven databases were searched from their inception to October 2010. Randomized clinical trials (RCTs) and non-randomized clinical trials (NRCTs) were considered, if they investigated any type of yoga in patients with asthma. The selection of studies, data extraction, and validation were performed independently by two reviewers.
Results: Six RCTs and one NRCT met the inclusion criteria. Their methodological quality was mostly poor. Three RCTs and one NRCT suggested that yoga leads to a significantly greater reduction in spirometric measures, airway hyperresponsivity, dose of histamine needed to provoke a 20% reduction in forced expiratory volume in the first second, weekly number of asthma attacks, and need for drug treatment. Three RCTs showed no positive effects compared to various control interventions.
Conclusions: The belief that yoga alleviates asthma is not supported by sound evidence. Further, more rigorous trials are warranted.
Some clinicians believe that spinal manipulation is an effective treatment for asthma. The aim of this systematic review was to critically evaluate the evidence for or against this claim. Four electronic databases were searched without language restrictions from their inceptions to September 2008. Bibliographies and departmental files were hand-searched. The methodological quality of all included studies was assessed with the Jadad score. Only randomised clinical trials of spinal manipulation as a treatment of asthma were included. Three studies met these criteria. All of them were of excellent methodological quality (Jadad score 5) and all used sham-manipulation as the control intervention. None of the studies showed that real manipulation was more effective than sham-manipulation in improving lung function or subjective symptoms. It is concluded that, according to the evidence of the most rigorous studies available to date, spinal manipulation is not an effective treatment for asthma.
Contradictory results from randomised controlled trials of acupuncture in asthma suggest both a beneficial and detrimental effect. The authors conducted a formal systematic review and meta-analysis of all randomised clinical trials in the published literature that have compared acupuncture at real and placebo points in asthma patients. The authors searched for trials published in the period 1970-2000. Trials had to measure at least one of the following objective outcomes: peak expiratory flow rate, forced expiratory volume in one second (FEV1) and forced vital capacity. Estimates of the standarised mean difference, between acupuncture and placebo were computed for each trial and combined to estimate the overall effect. Hetereogeneity was investigated in terms of the characteristics of the individual studies. Twelve trials met the inclusion criteria but data from one could not be obtained. Individual patient data were available in only three. Standardised differences between means ranging from 0.071 to 0.133, in favour of acupuncture, were obtained. The overall effect was not conventionally significant and it corresponds to an approximate difference in FEV1 means of 1.7. After exploring hetereogenenity, it was found that studies where bronchoconstriction was induced during the experiment showed a conventionally significant effect. This meta-analysis did not find evidence of an effect of acupuncture in reducing asthma. However, the meta-analysis was limited by shortcomings of the individual trials, in terms of sample size, missing information, adjustment of baseline characteristics and a possible bias against acupuncture introduced by the use of placebo points that may not be completely inactive. There was a suggestion of preferential publication of trials in favour of acupuncture. There is an obvious need to conduct a full-scale randomised clinical trial addressing these limitations and the prognostic value of the aetiology of the disease.
Background: Emotional stress can either precipitate or exacerbate both acute and chronic asthma. There is a large body of literature available on the use of relaxation techniques for the treatment of asthma symptoms. The aim of this systematic review was to determine if there is any evidence for or against the clinical efficacy of such interventions.
Methods: Four independent literature searches were performed on Medline, Cochrane Library, CISCOM, and Embase. Only randomised clinical trials (RCTs) were included. There were no restrictions on the language of publication. The data from trials that statistically compared the treatment group with that of the control were extracted in a standardised predefined manner and assessed critically by two independent reviewers.
Results: Fifteen trials were identified, of which nine compared the treatment group with the control group appropriately. Five RCTs tested progressive muscle relaxation or mental and muscular relaxation, two of which showed significant effects of therapy. One RCT investigating hypnotherapy, one of autogenic training, and two of biofeedback techniques revealed no therapeutic effects. Overall, the methodological quality of the studies was poor.
Conclusions: There is a lack of evidence for the efficacy of relaxation therapies in the management of asthma. This deficiency is due to the poor methodology of the studies as well as the inherent problems of conducting such trials. There is some evidence that muscular relaxation improves lung function of patients with asthma but no evidence for any other relaxation technique.
Background: Asthma is one of the most common chronic diseases in modern society and there is increasing evidence to suggest that its incidence and severity are increasing. There is a high prevalence of usage of complementary medicine for asthma. Herbal preparations have been cited as the third most popular complementary treatment modality by British asthma sufferers. This study was undertaken to determine if there is any evidence for the clinical efficacy of herbal preparations for the treatment of asthma symptoms.
Methods: Four independent literature searches were performed on Medline, Pubmed, Cochrane Library, and Embase. Only randomised clinical trials were included. There were no restrictions on the language of publication. The data were extracted in a standardised, predefined manner and assessed critically.
Results: Seventeen randomised clinical trials were found, six of which concerned the use of traditional Chinese herbal medicine and eight described traditional Indian medicine, of which five investigated Tylophora indica. Three other randomised trials tested a Japanese Kampo medicine, marihuana, and dried ivy leaf extract. Nine of the 17 trials reported a clinically relevant improvement in lung function and/or symptom scores.
Conclusions: No definitive evidence for any of the herbal preparations emerged. Considering the popularity of herbal medicine with asthma patients, there is urgent need for stringently designed clinically relevant randomised clinical trials for herbal preparations in the treatment of asthma.
Breathing techniques are used by a large proportion of asthma sufferers. This systematic review was aimed at determining whether or not these interventions are effective. Four independent literature searches identified six randomized controlled trials. The results of these studies are not uniform. Collectively the data imply that physiotherapeutic breathing techniques may have some potential in benefiting patients with asthma. The safety issue has so far not been addressed satisfactorily. It is concluded that too few studies have been carried out to warrant firm judgements. Further rigorous trials should be carried out in order to redress this situation.

So, if you suffer from asthma, my advice is to stay away from SCAM. This might be easier said than done because SCAM practitioners are only too willing to lure asthma patients into their cult. In 2003, we have demonstrated this phenomenon by conducting a survey with chiropractors. Here is our short paper in full:
Classic chiropractic theory claims that vertebral subluxation blocks the flow of ‘‘innate intelligence’’ which, in turn, affects the health of asthma patients (1). Chiropractictors often use spinal manipulation (SM) to correct such malalignments and treat asthma (2). Several clinical trials of chiropractic SM exist, but the most rigorous ones are clearly negative (3,4). Chronic medication with corticosteroids can lead to osteoporosis, a condition, which is a contra-indication to chiropractic SM (5). Given this background, we aimed to determine whether chiropractors would advise an asthma patient on long-term corticosteroids (5 years) to try chiropractic as a treatment for this condition.
All 350 e-mail addresses listed at www.interadcom.com/chiro/html were randomised into two groups. A (deceptive) letter from a (fictitious) patient was sent to group A while group B was asked for advice on chiropractic treatment for asthma as part of a research project. Thus, groups A and B were asked the same question in di¡erent contexts: is chiropractic safe and e¡ective for an asthma patient on long-term steroids. After data collection, respondents from group A were informed that the e-mail had been part of a research project.
Of 97 e-mails in group A, we received 31 responses (response rate = 32% (95% CI, 0.23^ 0.41)). Seventy-four per cent (23 respondents) recommended visiting a chiropractor (95% CI, 0.59^ 0.89). Thirty-five per cent (11 respondents) mentioned minimal or no adverse effects of SM (95% CI, 0.18 ^ 0.52). Three chiropractors responded that some adverse e¡ects exist, e.g. risk of bone fracture, or stroke. Two respondents noted that other investigations (X-rays, spinal and neurological examination) were required before chiropractic treatment. Three respondents suggested additional treatments and one warned about a possible connection between asthma and the measles vaccine. Of 77 e-mails sent to group B, we received 16 responses (response rate = 21% (95% CI, 0.17^ 0.25)). Eleven respondents (69%) recommended visiting a chiropractor (95% CI, 0.46 ^ 0.91). Ten respondents mentioned minimal or no adverse effects of SM (95% CI, 0.39^ 0.87). Five chiropractors responded that adverse effects of SM exist (e.g. bone fracture). Five respondents suggested pre-testing the patient to check bone density, allergy, diet, exercise level, hydration and blood. Additional treatments were recommended by three respondents. The pooled results of groups A and B suggested that the majority of chiropractors recommend chiropractic treatment for asthma and the minority mention any adverse effects.
Our results demonstrate that chiropractic advice on asthma therapy is as readily available over the Internet as it is likely to be misleading. The majority of respondents from both groups (72%) recommended chiropractic treatment. This usually entails SM, a treatment modality which has been demonstrated to be ineffective in rigorous clinical trials (3,4,6). The advice may also be dangerous: the minority of the respondents of both groups (17%) caution of the risk of bone fracture. Our findings also suggest that, for the research question asked, a degree of deception is necessary. The response rate in group B was 12% lower than that of group A, and the answers received differed considerably between groups. In group A, 10% acknowledged the possibility of adverse e¡ects, this figure was 33% in group B. In conclusion, chiropractors readily provide advice regarding asthma treatment, which is often not evidence-based and has the potential to put patients at risk.

As I stated above: if you suffer from asthma, my advice is to
stay away from SCAM.
Acupuncture for animals has a long history in China. In the West, it was introduced in the 1970s when acupuncture became popular for humans. A recent article sums up our current knowledge on the subject. Here is an excerpt:
Acupuncture is used mainly for functional problems such as those involving noninfectious inflammation, paralysis, or pain. For small animals, acupuncture has been used for treating arthritis, hip dysplasia, lick granuloma, feline asthma, diarrhea, and certain reproductive problems. For larger animals, acupuncture has been used for treating downer cow syndrome, facial nerve paralysis, allergic dermatitis, respiratory problems, nonsurgical colic, and certain reproductive disorders.Acupuncture has also been used on competitive animals. There are veterinarians who use acupuncture along with herbs to treat muscle injuries in dogs and cats. Veterinarians charge around $85 for each acupuncture session.[8]Veterinary acupuncture has also recently been used on more exotic animals, such as chimpanzees (Pan troglodytes)[9] and an alligator with scoliosis,[10] though this is still quite rare.
To put it in a nutshell: acupuncture for animals is not evidence-based.
How can I be so sure?
Because ref 1 in the text above refers to our paper. Here is its abstract:
Acupuncture is a popular complementary treatment option in human medicine. Increasingly, owners also seek acupuncture for their animals. The aim of the systematic review reported here was to summarize and assess the clinical evidence for or against the effectiveness of acupuncture in veterinary medicine. Systematic searches were conducted on Medline, Embase, Amed, Cinahl, Japana Centra Revuo Medicina and Chikusan Bunken Kensaku. Hand-searches included conference proceedings, bibliographies, and contact with experts and veterinary acupuncture associations. There were no restrictions regarding the language of publication. All controlled clinical trials testing acupuncture in any condition of domestic animals were included. Studies using laboratory animals were excluded. Titles and abstracts of identified articles were read, and hard copies were obtained. Inclusion and exclusion of studies, data extraction, and validation were performed independently by two reviewers. Methodologic quality was evaluated by means of the Jadad score. Fourteen randomized controlled trials and 17 nonrandomized controlled trials met our criteria and were, therefore, included. The methodologic quality of these trials was variable but, on average, was low. For cutaneous pain and diarrhea, encouraging evidence exists that warrants further investigation in rigorous trials. Single studies reported some positive intergroup differences for spinal cord injury, Cushing’s syndrome, lung function, hepatitis, and rumen acidosis. These trials require independent replication. On the basis of the findings of this systematic review, there is no compelling evidence to recommend or reject acupuncture for any condition in domestic animals. Some encouraging data do exist that warrant further investigation in independent rigorous trials.
This evidence is in sharp contrast to the misinformation published by the ‘IVAS’ (International Veterinary Acupuncture Society). Under the heading “For Which Conditions is Acupuncture Indicated?“, they propagate the following myth:
Acupuncture is indicated for functional problems such as those that involve paralysis, noninfectious inflammation (such as allergies), and pain. For small animals, the following are some of the general conditions which may be treated with acupuncture:
- Musculoskeletal problems, such as arthritis, intervertebral disk disease, or traumatic nerve injury
- Respiratory problems, such as feline asthma
- Skin problems such as lick granulomas and allergic dermatitis
- Gastrointestinal problems such as diarrhea
- Selected reproductive problems
For large animals, acupuncture is again commonly used for functional problems. Some of the general conditions where it might be applied are the following:
- Musculoskeletal problems such as sore backs or downer cow syndrome
- Neurological problems such as facial paralysis
- Skin problems such as allergic dermatitis
- Respiratory problems such as heaves and “bleeders”
- Gastrointestinal problems such as nonsurgical colic
- Selected reproductive problems
In addition, regular acupuncture treatment can treat minor sports injuries as they occur and help to keep muscles and tendons resistant to injury. World-class professional and amateur athletes often use acupuncture as a routine part of their training. If your animals are involved in any athletic endeavor, such as racing, jumping, or showing, acupuncture can help them keep in top physical condition.
And what is the conclusion?
Perhaps this?
Never trust the promotional rubbish produced by SCAM organizations.
This story made the social media recently:
Yes, I can well believe that many chiros are daft enough to interpret the incident in this way. Yet I think it’s a lovely story, not least because it reminds me of one of my own experiences:
I was on a plane to Toronto and had fallen asleep after a good meal and a few glasses of wine when a stewardess woke me saying: “We think you are a doctor!?”
“That’s right, I am a professor of alternative medicine”, I said trying to wake up.
“We have someone on board who seems to be dying. Would you come and have a look? We moved him into 1st class.”
Arrived in 1st class, she showed me the patient and a stethoscope. The patient was unconscious and slightly blue in the face. I opened his shirt and used the stethoscope only to find that this device is utterly useless on a plane; the sound of the engine by far overwhelms anything else. With my free hand, I tried to find a pulse – without success! Meanwhile, I had seen a fresh scar on the patient’s chest with something round implanted underneath. I concluded that the patient had recently had a pacemaker implant. Evidently, the electronic device had malfunctioned.
At this stage, two stewardesses were pressing me: “The captain needs to know now whether to prepare for an emergency stop in Newfoundland or to fly on. It is your decision.”
I had problems thinking clearly. What was best? The patient was clearly dying and there was nothing I could do about it. I replied by asking them to give me 5 minutes while I tried my best. But what could I do? I decided that I could do nothing but hold the patient’s hand and let him die in peace.
The Stewardesses watched me doing this and must have thought that I was trying some sort of energy healing, perhaps Reiki. This awkward situation continued for several minutes until – out of the blue – I felt a regular, strong pulse. Evidently, the pacemaker had started functioning again. It did not last long until the patient’s color turned pink and he began to talk. I instructed the pilot to continue our path to Toronto.
After I had remained with the patient for another 10 minutes or so, the Stewardesses came and announced: “We have moved your things into 1st class; like this, you can keep an eye on him.” The rest of the journey was uneventful – except the Stewardesses came repeatedly giving me bottles of champagne and fine wine to take with me into Toronto. And each time they politely asked whether my healing method would not also work for the various ailments they happened to suffer from – varicose veins, headache, PMS, fatigue …
So, here is my message to all the fellow energy healers out there:
We honor the creator’s design.
We know of the potential of the body is limitless.
Remember, you did not choose energy healing.
Energy healing chose you.
You were called for a time like this.
In case you are beginning to wonder whether I have gone round the bend, the answer is NO! I am not an energy healer. In fact, I am as much NOT an energy healer, as the chiropractor in the above story has NOT saved the life of his patient. Chiropractors and stewardesses, it seems to me, have one thing in common: they do not understand much about medicine.
PS
On arrival in Toronto, the patient was met by a team of fully equipped medics. I explained what had happened and they took him off to the hospital. As far as I know, he made a full recovery after the faulty pacemaker had been replaced. After my return to the UK, British Airways sent me a huge hamper to thank me.
There is a lack of data describing the state of naturopathic or complementary veterinary medicine in Germany. This survey maps the currently used treatment modalities, indications, existing qualifications, and information pathways. It records the advantages and disadvantages of these medicines as experienced by veterinarians. Demographic influences are investigated to describe the distributional impacts of using veterinary naturopathy and complementary medicine.
A standardized questionnaire was used for the cross-sectional survey. It was distributed throughout Germany in a written and digital format from September 2016 to January 2018. Because of the open nature of data collection, the return rate of questionnaires could not be calculated. To establish a feasible timeframe, active data collection stopped when the previously calculated limit of 1061 questionnaires was reached.
With the included incoming questionnaires of that day, a total of 1087 questionnaires were collected. Completely blank questionnaires and those where participants did not meet the inclusion criteria were not included, leaving 870 out of 1087 questionnaires to be evaluated. A literature review and the first test run of the questionnaire identified the following treatment modalities:
- homeopathy,
- phytotherapy,
- traditional Chinese medicine (TCM),
- biophysical treatments,
- manual treatments,
- Bach Flower Remedies,
- neural therapy,
- homotoxicology,
- organotherapy,
- hirudotherapy.
These were included in the questionnaire. Categorical items were processed using descriptive statistics in absolute and relative numbers based on the population of completed answers provided for each item. Multiple choices were possible.
Overall 85.4% of all the questionnaire participants used naturopathy and complementary medicine. The treatments most commonly used were:
- complex homoeopathy (70.4%, n = 478),
- phytotherapy (60.2%, n = 409),
- classic homoeopathy (44.3%, n = 301),
- biophysical treatments (40.1%, n = 272).
The most common indications were:
- orthopedic (n = 1798),
- geriatric (n = 1428),
- metabolic diseases (n = 1124).
Over the last five years, owner demand for naturopathy and complementary treatments was rated as growing by 57.9% of respondents (n = 457 of total 789). Veterinarians most commonly used scientific journals and publications as sources for information about naturopathic and complementary contents (60.8%, n = 479 of total 788). These were followed by advanced training acknowledged by the ATF (Academy for Veterinary Continuing Education, an organisation that certifies independent veterinary continuing education in Germany) (48.6%, n = 383). The current information about naturopathy and complementary medicine was rated as adequate or nearly adequate by many (39.5%, n = 308) of the respondents.
The most commonly named advantages in using veterinary naturopathy and complementary medicine were:
- expansion of treatment modalities (73.5%, n = 566 of total 770),
- customer satisfaction (70.8%, n = 545),
- lower side effects (63.2%, n = 487).
The ambiguity and unclear evidence of the mode of action and effectiveness (62.1%, n = 483) and high expectations of owners (50.5%, n = 393) were the disadvantages mentioned most frequently. Classic homoeopathy, in particular, has been named in this context (78.4%, n = 333 of total 425). Age, gender, and type of employment showed a statistically significant impact on the use of naturopathy and complementary medicine by veterinarians (p < 0.001). The university of final graduation showed a weaker but still statistically significant impact (p = 0.027). Users of veterinary naturopathy and complementary medicine tended to be older, female, self-employed and a higher percentage of them completed their studies at the University of Berlin. The working environment (rural or urban space) showed no statistical impact on the veterinary naturopathy or complementary medicine profession.
The authors concluded that this is the first study to provide German data on the actual use of naturopathy and complementary medicine in small animal science. Despite a potential bias due to voluntary participation, it shows a large number of applications for various indications. Homoeopathy was mentioned most frequently as the treatment option with the most potential disadvantages. However, it is also the most frequently used treatment option in this study. The presented study, despite its restrictions, supports the need for a discussion about evidence, official regulations, and the need for acknowledged qualifications because of the widespread application of veterinary naturopathy and complementary medicine. More data regarding the effectiveness and the mode of action is needed to enable veterinarians to provide evidence-based advice to pet owners.
I can only hope that the findings are seriously biased and not a true reflection of the real situation. The methodology used for recruiting participants (it is fair to assume that those vets who had no interest in SCAM did not bother to respond) strongly indicates that this might be the case. If, however, the findings were true, one would have to conclude that, for German vets, evidence-based healthcare is still an alien concept. The evidence that the preferred SCAMs are effective for the listed conditions is very weak or even negative. If the findings were true, one would need to wonder how much of veterinary SCAM use amounts to animal abuse.
WARNING: SATIRE
This is going to be a very short post. Yet, I am sure you agree that my ‘golden rules’ encapsulate the collective wisdom of so-called alternative medicine (SCAM):
- Conventional treatments are dangerous
- Conventional doctors are ignorant
- Natural remedies are by definition good
- Ancient wisdom knows best
- SCAM tackles the roots of all health problems
- Experience trumps evidence
- People vote with their feet (SCAM’s popularity and patients’ satisfaction prove SCAM’s effectiveness)
- Science is barking up the wrong tree (what we need is a paradigm shift)
- Even Nobel laureates and other VIPs support SCAM
- Only SCAM practitioners care about the whole individual (mind, body, and soul)
- Science is not yet sufficiently advanced to understand how SCAM works (the mode of action has not been discovered)
- SCAM even works for animals (and thus cannot be a placebo)
- There is reliable evidence to support SCAM
- If a study of SCAM happens to yield a negative result, it is false-negative (e.g. because SCAM was not correctly applied)
- SCAM is patient-centered
- Conventional medicine is money-orientated
- The establishment is forced to suppress SCAM because otherwise, they would go out of business
- SCAM is reliable, constant, and unwavering (whereas conventional medicine changes its views all the time)
- SCAM does not need a monitoring system for adverse effects because it is inherently safe
- SCAM treatments are individualized (they treat the patient and not just a diagnostic label like conventional medicine)
- SCAM could save us all a lot of money
- There is no health problem that SCAM cannot cure
- Practitioners of conventional medicine have misunderstood the deeper reasons why people fall ill and should learn from SCAM
QED
I am sure that I have forgotten several important rules. If you can think of any, please post them in the comments section.
This randomized, double-blind, placebo-controlled trial investigated whether homeopathic Hypericum leads to a reduction in postoperative pain and a decrease in pain medication compared with placebo. Inpatients undergoing lumbar sequestrectomy surgery were given the homeopathic treatment Hypericum C200 or a placebo in addition to usual pain management. The primary endpoint was pain relief measured with a visual analog scale. Secondary endpoints were the reduction of inpatient postoperative analgesic medication and change in sensory and affective pain perception.
The baseline characteristics were comparable between the two groups. Pain perception between baseline and day 3 did not significantly differ between the study arms. With respect to pain medication, total morphine equivalent doses did not differ significantly. However, a statistical trend and a moderate effect (d = 0.432) in the decrease of pain medication consumption in favor of the Hypericum group was observed.
The authors concluded that this is the first trial of homeopathy that evaluated the efficacy of Hypericum C200 after lumbar monosegmental spinal sequestrectomy. Although no significant differences between the groups could be shown, we found that patients who took potentiated Hypericum in addition to usual pain management showed lower consumption of analgesics. Further investigations, especially with regard to pain medication, should follow to better classify the described analgesic reduction.
I applaud the authors from the Institute of Integrative Medicine, Witten/Herdecke University, Herdecke, Germany (not an institution known for its objectivity in SCAM) to have published this negative study in a journal that is so clearly pro-SCAM that it very rarely contains anything in its pages that is not positive about SCAM. Yet, I am baffled by two things:
- The plant Hypericum is used in SCAM as a painkiller. According to the ‘like cures like’ axiom of homeopathy, it should thus INCREASE the pain of post-op patients.
- The researchers used a C 200 potency. I ask myself, how can anyone assume that such a dilution has any effect at all? C200 means that the plant tincture is diluted at a ratio of 1: 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000. Less than one molecule of the plant per several universes!
To believe that such a dilution might work, one really needs to be a convinced disciple of Hahnemann. Yet, to disregard the ‘like cures like’ axiom, one needs to be what he called ‘a traitor’ to his true art of healing.
I think this press release might interest you:
Science advocates have filed a groundbreaking lawsuit against Boiron, Inc., one of the largest manufacturers of homeopathic products in the world, for deceiving vulnerable consumers with useless products dressed up to look like real medicine. The Center for Inquiry (CFI), which fights on behalf of consumers against pseudoscience, says Boiron routinely made false claims about what its products will treat and heal, misleading the public about the absurd pseudoscientific basis for Boiron products, and even lying about the ingredients their products contain.
“The facts could not be more clear. Boiron profits massively by deceiving consumers in their time of need,” said CFI Vice President and Legal Counsel Nick Little. “Boiron knows its products are worthless junk, so they do everything they can to obscure the truth in order to offload their snake oil upon the unwitting, the ill-informed, and the vulnerable. They can’t be allowed to get away with it any longer.”
Adherents of homeopathy claim, without evidence, that a substance which causes harm to a healthy person will cure anyone else suffering the same type of harm. In homeopathic products, the “active” ingredients are highly diluted mixtures of the so-called cures; the ingredient ends up so diluted, often literally no trace of the original substance remains. Manufacturers like Boiron then sell miniscule amounts of the already incredibly diluted ingredients and promise astounding results.
In its lawsuit, brought under the District of Columbia Consumer Protection Procedures Act, CFI alleges that Boiron sold a plethora of materially identical products, each made up of sugar pills and powders. Despite no scientifically detectable active ingredient, Boiron falsely promised consumers that each item would treat and cure a particular illness, injury, or health condition.
“Boiron sells little pills of sugar with grandiose claims. It’s hard to believe anyone would try to pass off such junk as a surefire way to treat painful skin problems, heal mental health issues, and even to counteract menopause,” said CFI Staff Attorney Aaron D. Green. “But Boiroin has been doing just that by tricking consumers into risking their health and throwing away their money on its fancy faux ‘medicines.’ It’s time for Boiron and all homeopathy hucksters to be held accountable.”
In its complaint, CFI notes that Boiron sells Saccharum officinale as a treatment for “nervous agitation in children after overindulgence.”
“Most parents would rightfully be skeptical of this product if Boiron told them what Saccharum officinale actually is,” said Green. “Table sugar.”
According to recent industry accounts, 85 percent of consumers who purchased homeopathic products did not realize they were homeopathic, and nine out of ten consumers did not even know what the term homeopathic meant.
Apart from selling products they know are useless, Boiron also misrepresented the products’ ingredients. Four Boiron products were analyzed by an independent lab, and, not only were no traces of the supposed active ingredient found, even one of the inactive ingredients could not be scientifically detected.
The Center for Inquiry is currently engaged in other lawsuits regarding homeopathy, including consumer protection cases against megaretailers CVS and Walmart for their sale and marketing of homeopathic products, the matter recently heard by the DC Court of Appeals. CFI is also engaged in an active Freedom of Information Act lawsuit that demands the Department of Health and Human Services grant the public access to the Homeopathic Pharmacopoeia of the United States (HPUS), the “bible of homeopathy” upon which federal regulation of homeopathy is based and to which the industry restricts access but for those willing to pay thousands of dollars for the privilege.

All I can add to this is: good luck to the CFI and let’s hope reason will prevail!
The Anglo-European College of Chiropractic (AECC) has been promoting pediatric chiropractic for some time, and I have posted about the subject before (see, for instance, here). Now the AECC has gone one decisive step further. On the website, the AECC announced an MSc ‘Musculoskeletal Paediatric Health‘:
The MSc Musculoskeletal Paediatric Health degree is designed to develop your knowledge and skills in the safe and competent care of children of all ages. Our part-time, distance-based course blends live online classes with ready to use resources through our virtual learning environment. In addition, you will have the opportunity to observe in the AECC University College clinical services at our Bournemouth campus. The course covers topics in paediatric musculoskeletal practice with specific units on paediatric development, paediatric musculoskeletal examination, paediatric musculoskeletal interventions, and paediatric musculoskeletal management. You will address issues such as risk factors and public health, including breastfeeding, supine sleep in infancy, physical activity in children and conditions affecting the musculoskeletal health of children from birth. The paediatric specific topics are completed by other optional units such as professional development, evidence-based practice, and leadership and inter-professional collaboration. In the dissertation unit you will conduct a study relevant to musculoskeletal paediatric health.
Your learning will happen through a mix of live and recorded lectures, access to online reading materials, and access to the literature through our learning services. You will also engage with the contents taught through guided activities with your peers and staff. Clinical paediatric experience is recommended to fully engage with the course. For students with limited access to a suitable clinical environment to support their studies, or for student who wants to add to their clinical experience, we are able to offer a limited number of opportunities to observe and work alongside our clinical educators within the AECC University College clinical services. Assessments are tailor made to each unit and may include a variety of methods such as critical reviews, reflective accounts, portfolios and in the last year a research dissertation.

The AECC emphasizes its commitment to being a leading higher education institution in healthcare disciplines, nationally and internationally recognised for quality and excellence. Therefore, it seems only fair to have another look at the science behind pediatric chiropractic. Specifically, is there any good science to show that would justify a Master of Science in ‘Musculoskeletal Paediatric Health’?
So, let’s have a look and see whether there are any good review articles supporting such a degree. Here is what I found with several Medline searches (date of the review on chiropractic for any pediatric conditions, followed by its conclusion + link [so that the reader can look up the evidence]):
2008
I am unable to find convincing evidence for any of the above-named conditions.
2009
Previous research has shown that professional chiropractic organisations ‘make claims for the clinical art of chiropractic that are not currently available scientific evidence…’. The claim to effectively treat otitis seems to
be one of them. It is time now, I think, that chiropractors either produce the evidence or abandon the claim.
2009
The … evidence is neither complete nor, in my view, “substantial.”
2010
2018
What seems to emerge is rather disappointing:
- There are no really new reviews.
- Most of the existing reviews are not on musculoskeletal conditions.
- All of the reviews cast considerable doubt on the notion that chiropractors should go anywhere near children.
But perhaps I was too ambitious. Perhaps there are some new rigorous clinical trials of chiropractic for musculoskeletal conditions. A few further searches found this (again year and conclusion):
2019
2018
I might have missed one or two trials because I only conducted rather ‘rough and ready’ searches, but even if I did: would this amount to convincing evidence? Would it be good science?
No! and No!
So, why does the AECC offer a Master of Science in ‘Musculoskeletal Paediatric Health’?
Search me!
…
…
It wouldn’t have something to do with the notion that it is good for business?
Or perhaps they just want to give science a bad name?
Anyone who has been following this blog will have noticed that we have our very own ‘resident chiro’ who comments every single time I post about spinal manipulation/chiropractic/back pain. He uses (mostly?) the pseudonym ‘DC’. Recently, DC explained why he is such an avid poster of comments:
” I read and occasionally comment on this blog for two main reasons. 1. In my opinion Ernst doesn’t do a balance reporting on the papers his shares regarding spinal manipulation and chiropractic. Thus, I offer additional insight, a more balanced perspective for the readers. 2. There are a couple of skeptics who occasionally post that do a good job of analyzing papers or topics and they do so in a respectful manner. I enjoy reading their comments. I will add a third. 3. Ernst, from what I can tell, doesn’t censor people just because they have a different view.”
So, DC aims at offering additional insights and a more balanced perspective. That would certainly be laudable and welcome. Yet, over the years, I have gained a somewhat different impression. Almost invariably, my posts on the named subjects cast doubt on the notion that chiropractic generates more good than harm. This, of course, cannot be to the liking of chiropractors, who therefore try to undermine me and my arguments. In a way, that is fair enough.
DC, however, seems to have long pursued a very specific and slightly different strategy. He systematically attempts to distract from the evidence and arguments I present. He does that by throwing in the odd red herring or by deviating from the subject in some other way. Thus he hopes, I assume, to distract from the point that chiropractic fails to generate more good than harm. In other words, DC is a tireless (and often tiresome) fighter for the chiropractic cause and reputation.
To check whether my impression is correct, I went through the last 10 blogs on spinal manipulation/ chiropractic/ back pain. Here are my findings (first the title of and link to the blog in question, followed by one of DC’s originals distractions)
No 1
Chiropractic: “a safe form of treatment”? (edzardernst.com)
“It appears conventional medicine has a greater number of AE. This is not surprising.”
correct!
real doctors treat really sick patients
So the probability of an AE increases based upon how sick a patient is? Is there research that supports that?
No 2
Malpractice Litigation Involving Chiropractic Spinal Manipulation (edzardernst.com)
It would be interesting to know more about these 38 cases that weren’t included since that’s almost half of the 86 cases. What percentage of those cases involved SMT by a non chiropractor?
“Query of the VerdictSearch online legal database for “chiropractor” OR “chiropractic” OR “spinal manipulation” within the 22,566 listed cases classified as “medical malpractice” yielded 86 cases. Of these, 48 cases met the inclusion criteria by featuring a chiropractic practitioner as the primary defendant.”
No 3
there are three basic types of disc herniation
contained herniation
non-contained herniation
sequestered herniation
Some add a forth which are:
disc protrusion
prolapsed disc
disc extrusion
sequestered disc
where the first two are considered incomplete (contained) and the last two are called complete (non-contained) but they are all classified as a disc herniation.
You’re welcome

Acute Subdural Hemorrhage Following Cervical Chiropractic Manipulation (edzardernst.com)
sigh, my use of the word require was pointing out that different problems require different solutions.
You confuse a lack of concern with my critical analysis of what some use as evidence of serious harm.
I have only used one other identifier on this blog. Some objected to my use of the word Dr in that identifier so I changed it to DC as it wasn’t worth my time to argue with them (which of course DC still refers to Doctor but it seemed to appease them).
In healthcare and particularly in manual therapy we look at increasing comfort and function because most come to us because…wait for it…a loss of comfort and function.
Yes, there is the potential to cause harm, I have never said otherwise. Most case reports suggest that serious harm is due to an improper history and exam (although other reasons may exist such as improper technique). Thus, most cases appear to be preventable with a proper history, exam and technique. That, is a different problem that, yes, requires a different solution.
So yes, spinal manipulation isn’t “required” anymore than physical therapy, NSAIDs, etc for most cases. The question is: does the intervention increase comfort and function over doing nothing and is that justified due the potential risk of harm….benefit vs risk.
Now, i shall excuse my self to prepare for a research presentation that deals with a possible new contraindication to cSMT (because I have a lack of concern, right?)
No 8
Hmmm, let’s change that a bit…
The best approach is to consider the totality of the available evidence. By doing this, one cannot exclude the possibility that NSAIDs and opioids cause serious adverse effects. If that is so, we must abide by the precautionary principle which tells us to use other treatments that seem safer and at least as effective.
So based upon the totality of the available evidence, which is safer and at least as effective: cervical spinal manipulation vs NSAIDs/opioids?
No 9
Chiropractic spinal manipulation is not safe! (edzardernst.com)
getting the patient to sign something describing the risks. This is apparently something chiropractors don’t do before a neck manipulation.
Apparently?
No 10
Vertebral artery dissection in a pregnant woman after cervical spine manipulation (edzardernst.com)
Most case reports fail on one of two criteria, sometimes both.
1. No clear record of why the patient sought chiropractic care (symptoms that may indicate a VAD in progress or not)
2. Eliminating any other possible causes of the VAD especially in the week prior to SMT.
I would have to search but I recall a case report of a woman presenting for maintenance care (no head or neck symptoms at the time) and after cSMT was dx with a VAD. Asymptomatic VADs are very rare thus there is a high probability that cSMT induced the VAD in that case, IMO.
Although not published I had a dialogue with a MD where a patient underwent a MRI, had cSMT the next day and developed new symptoms thus another MRI was shortly done and was dx with a VAD. I encouraged her to publish the case but apparently she did not.
There was a paper published that looked at the quality of these case reports, most are poor.

I might be mistaken but DC systematically tries to distract from the fact that chiropractic does not generate more good than harm and that there is a continuous flow of evidence suggesting it does, in fact, the exact opposite. He (I presume he is male) might not even do this consciously in which case it would suggest to me that he is full of quasi-religious zeal and unable to think critically about his own profession and creeds.
Reviewing the material above, I also realized that, by engaging with DC (and other zealots of this type), it is I who often gives him the opportunity to play his game. Therefore, I will from now on try harder to stick to my own rules that say:
- Comments must be on-topic.
- I will not post comments which are overtly nonsensical.
- I will not normally enter into discussions with people who do not disclose their full identity.
The German Heilpraktiker has been the subject of several of my posts. Some claim that it is an example of a well-established and well-regulated profession. Others insist that it is a menace endangering public health in Germany.
Who is right?
One answer might be found by looking at the training the German Heilpraktiker receives.
In Germany, non-medical practitioners (NMPs; or ‘Heilpraktiker’) offer a broad range of so-called alternative medicine (SCAM) methods. The aim of this investigation was to characterize schools for NMPs in Germany in terms of basic (medical) training and advanced education.
The researchers found 165 schools for NMPs in a systematic web-based search. As the medical board examination NMPs must take before building a practice exclusively tests their knowledge in conventional medicine, schools hardly include training in SCAM methods. Only a few schools offered education in SCAM methods in their NMP training. Although NMP associations framed requirements for NMP education, 83.0% (137/165) of schools did not meet these requirements.
The authors concluded that patients and physicians should be aware of the lack of training and consequent risks, such as harm to the body, delay of necessary treatment, and interaction with conventional drugs. Disestablishing the profession of NMPs might be a reasonable step.
Other interesting facts disclosed by this investigation include the following:
- There is no mandatory training for NMPs. Some attend schools but many do not and prefer to learn exclusively from books.
- The training programs of the NMP schools comprise an average of 7.4 hours per week of classroom teaching for an average of 27.1 months.
- Course participants thus complete an average of ~600 hours of training. (A degree in medicine takes an average of 12.9 semesters. With a weekly working time of 38.9 hours, this amounts to ~15,000 hours of training excluding internships etc.)
- Three-quarters of all NMP schools do not offer any practical teaching units.
- If training programs do contain practical instruction, it is usually limited to individual weekend workshops in which the measurement of vital data, physical examinations, and injections and infusions are practiced.
- The exam that NMPs have to pass consists of a written test with sixty multiple-choice questions and a 30 to 60-minute interview on case studies.
- The examination covers professional and legal anatomical and physiological basics, methods of anamnesis and diagnosis, the significance of basic laboratory values as well as practice hygiene and disinfection.
- Not included are competence in pharmacology, pathophysiology, biochemistry, microbiology, human genetics and immunology.
- The average 600 hours of training of an NMP is thus ~5% of that of a medical student.
- If an NMP fails the exam, she can repeat it as often as she needs to pass.
- The day after the exam, an NMP can open her own practice and is allowed (with only very few exceptions) to do most of what proper doctors do.
So are NMPs a danger to public health in Germany?
I let you answer this question yourself.
