I just came across a website that promised to”cover 5 common misconceptions about alternative medicine that many people have”. As much of this blog is about this very issue, I was fascinated. Here are Dr Cohen’s 5 points in full:
5 Misconceptions about Alternative Medicine Today
1. Alternative Medicine Is Only an Alternative
In fact, many alternative practitioners are also medical doctors, chiropractors, or other trained medical professionals. Others work closely with MDs to coordinate care. Patients should always let all of their health care providers know about treatments that they receive from all the others.
2. Holistic Medicine Isn’t Mainstream
In fact, scientists and doctors do perform studies on all sorts of alternative therapies to determine their effectiveness. These therapies, like acupuncture and an improved diet, pass the test of science and then get integrated into standard medical practices.
3. Natural Doctors Don’t Use Conventional Medicine
No credible natural doctor will ever tell a patient to replace prescribed medication without consulting with his or her original doctor. In many cases, the MD and natural practitioner are the same person. If not, they will coordinate treatment to benefit the health of the patient.
4. Alternative Medicine Doesn’t Work
Actual licensed health providers won’t just suggest natural therapies on a whim. They will consider scientific studies and their own experience to suggest therapies that do work. Countless studies have, for example, confirmed that acupuncture is an effective treatment for many medical conditions. Also, the right dietary changes are known to help improve health and even minimize or cure some diseases. Numerous other alternative therapies have been proven effective using scientific studies.
5. Big Medical Institutions are Against Alternative Medicine
According to a recent survey, about half of big insurers pay for tested alternative therapies like acupuncture. Also, hospitals and doctors do recognize that lifestyle changes, some herbal remedies, and other kinds of alternative medicine may reduce side effects, allow patients to reduce prescription medicine, and even lower medical bills.
This is not to say that every insurer, doctor, or hospital will support a particular treatment. However, patients are beginning to take more control of their health care. If their own providers won’t suggest natural remedies, it might be a good idea to find one who does.
The Best Medicine Combines Conventional and Alternative Medicine
Everyone needs to find the right health care providers to enjoy the safest and most natural care possible. Good natural health providers will have a solid education in their field. Nobody should just abandon their medical treatment to pursue alternative cures. However, seeking alternative therapies may help many people reduce their reliance on harsh medications by following the advice of alternative providers and coordinating their care with all of their health care providers.
END OF COHEN’S TEXT
COMMENT BY MYSELF
Who the Dickens is Dr Cohen and what is his background? I asked myself after reading this. From his website, it seems that he is a chiropractor from North Carolina – not just any old chiro, but one of the best!!! – who also uses several other dubious therapies. He sums up his ‘philosophy’ as follows:
There is an energy or life force that created us (all 70 trillion cells that we are made of) from two cells (sperm and egg cells). This energy or innate intelligence continues to support you throughout life and allows you to grow, develop, heal, and express your every potential. This life force coordinates all cells, tissues, muscles and organs by sending specific, moment by moment communication via the nervous system. If the nervous system is over-stressed or interfered with in any way, then your life force messages will not be properly expressed.
Here he is on the cover of some magazine and here is also his ‘PAIN CLINIC’
Fascinating stuff, I am sure you agree.
As I do not want to risk a libel case, I will abstain from commenting on Dr Cohen and his methods or beliefs. Instead I will try to clear up a few misconceptions that are pertinent to him and the many other practitioners who are promoting pure BS via the Internet.
- Not everyone who uses the title ‘Dr’ is a doctor in the sense of having studied medicine.
- Chiropractors are not ‘trained medical professionals’.
- The concepts of ‘vitalism’, ‘life force’ etc. have been abandoned in real heath care a long time ago, and medicine has improved hugely because of this.
- Hardly any alternative therapy has ‘passed the test of science’.
- Therefore, it is very doubtful whether alternative practitioners actually will ‘consider scientific studies’.
- True, some trials did suggest that acupuncture is an effective treatment for many medical conditions; but their methodological quality is often far too low to draw firm conclusions and many other, often better studies have shown the contrary.
- Numerous other alternative therapies have been proven ineffective using scientific studies.
- Therefore it might be a good idea to find a health care provider who does not offer unproven treatments simply to make a fast buck.
- Seeking alternative therapies may harm many people.
If you talk to advocates of homeopathy, you are bound to hear claims that are false or misleading; in fact, you hear them so regularly that you might begin to doubt the truth. For those who have such doubts or are in need of some correct counter-arguments, I have listed here those 12 bogus claims which, in my experience, are most common together with short, suitable, and factual rebuttals.
1) THERE IS NOTHING MYSTERIOUS ABOUT HOMEOPATHY’S MODE OF ACTION, IT WORKS LIKE VACCINATIONS
This argument is used by enthusiasts in response the fact that most homeopathic remedies are too highly diluted to have pharmacological effects. Vaccines are also highly diluted and they are, of course, very effective; therefore, so the bogus notion, there is nothing odd about homeopathy.
The argument is wrong on several levels; the easiest way to refute, I think, it is to point out that vaccines contain measurable amounts of material and lead to measurable changes in the immune system. By contrast, the typical homeopathic remedy (beyond the C12 potency) contains not a single molecule of an active substance and leads to no measurable changes in any system.
2) SIGNIFICANTLY MORE CONTROLLED CLINICAL TRIALS OF HOMEOPATHY ARE POSITIVE THAN NEGATIVE
Several websites of homeopathic organisations make this claim and even provide simple statistics to back it up. Consequently, many homeopathy fans have adopted it.
The statistics they present show that x % of studies are positive, y % are negative and z % are neutral; the whole point is that x is larger than y. The percentage figures may even be correct but they rely on the spurious definitions used: positive = superior to placebo, negative = placebo superior to homeopathy, neutral = no difference between homeopathy and placebo. The latter category was created so that homeopathy comes out trumps.
For all intents and purposes, a study where the experimental treatment is no better than placebo is not a study neutral but a negative result. Thus the negative category in such statistics must be y + z which is, of course, larger than x. In other words, the majority of trials is, in truth, negative.
3) HOMEOPATHY IS SUPPORTED BY NOBEL PRIZE WINNERS
I don’t know of a single Nobel Prize winner who has stated or implied that homeopathy works better than a placebo. Some have tried to find a mechanism of action for homeopathy by doing some basic research and have published theories about it. None of those has been accepted by science.
And if there ever should be a Nobel Prize winner or similarly brilliant person who supports homeopathy, this would merely show that even bright individuals can make mistakes!
4) HOMEOPATHY IS SAFE
Tell that to the child that has just been reported to have died because her parents used homeopathy for an ear infection which (could have been easily treated with antibiotics but) degenerated into a brain abscess with homeopathic therapy. There are many more such tragic cases than I care to remember.
The risks of homeopathy are, of course, minor compared to many conventional treatments, but the risk/benefit balance of homeopathy can never be positive because, unlike those high risk conventional treatments, it has no benefit.
5) HOMEOPATHY DOES NOT LEND ITSELF TO BEING TESTED IN CLINICAL TRIALS
The best way to disprove this argument is to point out that ~ 250 controlled clinical trials are currently available. Every homeopath on the planet boasts about clinical trials – provided they are positive.
6) HOMEOPATHY WORKS VIA QUANTUM ENTANGLEMENT
I do not understand quantum mechanics and, I suspect, neither do the homeopaths who use this argument. But physicists who do understand this subject well are keen to stress that homeopathy cannot be explained in this way.
7) THERE IS NO PROOF THAT HOMEOPATHY DOES NOT WORK
The absence of evidence is not the same as evidence of absence, homeopaths like to exclaim. And they are, of course, correct! However, they forget that, science cannot prove a negative and that, in routine health care, we do not even look for a proof of ineffectiveness. We use those treatments that have a positive proof of effectiveness – everything else is irresponsible.
8) EVEN IF HOMEOPATHY WERE JUST A PLACEBO, IT STILL HELPS PATIENTS AND IS THEREFORE A USEFUL TREATMENT
It is true, of course, that placebo effects can help patients. But it is not true that, for generating a placebo response, we need a placebo. If a clinician administers an effective treatment with compassion, the patient will benefit from a placebo response plus from the specific effects of the treatment. Only giving placebos is therefore tantamount to cheating the patient.
9) THERE IS A WORLDWIDE CONSPIRACY AGAINST HOMEOPATHY
In a way, this argument merely suggests that homeopathic remedies are ineffective in treating paranoia. I have not ever seen a jot of evidence for it – and neither can anyone who uses this claim produce any.
10) YOU NEED TO BE A HOMEOPATH TO BE ABLE TO UNDERSTAND AND ADEQUATELY JUDGE THE VALUE OF HOMEOPATHY
With this notion, homeopaths want to claim that the critics of homeopathy are incompetent. It is like saying that only people who believe in god are allowed to criticise religion. By definition, homeopaths are believers, and therefore they are unlikely to be free of bias when judging the value of homeopathy. Homeopathy is a health technology that must be evaluated like all other health technologies: by independent scientists who know their job.
11) HOMEOPATHY HAS BEEN PROVEN TO WORK FOR LITTLE CHILDREN AND ANIMALS
The argument here is that animals and children cannot possibly respond to placebo. Therefore homeopathy must be more than a placebo.
This notion is twice wrong. Firstly, both animals and children can respond to placebo, if only ‘by proxy’, i.e. via their carers. Secondly, if we consider the totality of the reliable data, we find that neither for children nor for animals is the evidence convincingly positive.
12) HOMEOPATHY HAS BEEN USED VERY SUCCESSFULLY IN MAJOR EPIDEMICS, AND THAT FACT IS PROOF ENOUGH FOR ITS EFFICACY
Yes, there are some rather fascinating historical accounts which homeopaths interpret in this fashion. But if we look a little closer, we invariably find explanations which are much more plausible than the assumption of homeopathy’s effectiveness. Epidemiological observations of this nature can almost never establish cause and effect, and the clinical outcome could have been due to a myriad of confounders unrelated to homeopathy.
Necessity, they say, is the mother of invention. The meaning of this proverb is fairly clear:
- In the Oxford Dictionary the proverb has been defined as– when the need for something becomes imperative, you are forced to find ways of getting or achieving it.
- According to the Cambridge Dictionary, this is “an expression that means that if you really need to do something, you will think of a way of doing it.”
- Finally, the Longman dictionary has defined the proverb as– “if someone really needs to do something, they will find a way of doing it.”
In the world of chiropractic the proverb acquires a special meaning: chiropractic relies almost entirely on inventions. A few examples have to suffice:
- first, instead of pathophysiology, they invented subluxations,
- this required the invention of adjustments which were needed for their imagined subluxation,
- then they invented the ‘inate’,
- then they invented the idea that all sorts of conditions are caused by subluxations and therefore require adjustments,
- finally, they invented the notion that regular adjustments are needed for a healthy person to stay healthy.
I was reminded of the unique inventive capacity of chiropractic when I came across the website of the Foundation for Chiropractic Progress (F4CP). The F4CP is, according to their own statements, a not-for-profit organization dedicated to raising awareness about the value of chiropractic care (which is, of course, another invention).
Experts at the F4CP point out that a growing number of professional athletic teams utilize chiropractic care to maximize overall health and maintain peak performance. “Repetitive motion injuries, including shoulder tendinitis, elbow, lower back pain and muscle spasms, are common conditions and injuries among professional baseball players that can be successfully prevented, managed and treated with chiropractic care,” says Hirad N. Bagy, DC. “Chiropractic adjustments, in conjunction with soft tissue mobilization, provide athletes with proper structure, function and balance to reduce the risk of injury, accelerate recovery time and improve overall performance,” he continues – and he must know, because he has received specialized training and certifications specific to sports medicine, which include the Graston Technique®, Active Release Technique®, Myofascial Release Technique, Impact Concussion Testing and Functional Dry Needling. Dr. Bagy continues: “A number of athletes that I treat regularly understand the importance of chiropractic maintenance care, and also seek treatment when an injury arises. Through the restoration of proper bio-mechanics, doctors of chiropractic are now positioned as key health care providers throughout all of the sports teams that I work with.”
BRAVO! We are impressed! So much so, that we almost forgot to ask: “Is there any evidence for all of these therapeutic claims?”
Just as well! Because had we asked and perhaps even did a bit of research, we would have found that almost none of these far-reaching claims are evidence-based.
But who would be so petty? Instead of criticising the incessant flow of bogus claims made by chiropractors worldwide, we should really admire their remarkable skill of invention:
- When the need for profit becomes imperative, CHIROPRACTORS are forced to find ways of getting or achieving it.
- If CHIROPRACTORS really need to do something, they will think of a way of doing it.
- If a CHIROPRACTOR really needs money, he will advocate ‘maintenance care’.
AND THAT’S WHAT IS CALLED ‘CHIROPRACTIC PROGRESS’!
You may feel that homeopaths are bizarre, irrational, perhaps even stupid – but you cannot deny their tenacity. Since 200 years, they are trying to convince us that their treatments are effective beyond placebo. And they seem to get more and more bold with their claims: while they used to suggest that homeopathy was effective for trivial conditions like a common cold, they now have their eyes on much more ambitious things. Two recent studies, for instance, claim that homeopathic remedies can help cancer patients.
The aim of the first study was to evaluate whether homeopathy influenced global health status and subjective wellbeing when used as an adjunct to conventional cancer therapy.
In this pragmatic randomized controlled trial, 410 patients, who were treated by standard anti-neoplastic therapy, were randomized to receive or not receive classical homeopathic adjunctive therapy in addition to standard therapy. The main outcome measures were global health status and subjective wellbeing as assessed by the patients. At each of three visits (one baseline, two follow-up visits), patients filled in two questionnaires for quantification of these endpoints.
The results show that 373 patients yielded at least one of three measurements. The improvement of global health status between visits 1 and 3 was significantly stronger in the homeopathy group by 7.7 (95% CI 2.3-13.0, p=0.005) when compared with the control group. A significant group difference was also observed with respect to subjective wellbeing by 14.7 (95% CI 8.5-21.0, p<0.001) in favor of the homeopathic as compared with the control group. Control patients showed a significant improvement only in subjective wellbeing between their first and third visits.
Our homeopaths concluded that the results suggest that the global health status and subjective wellbeing of cancer patients improve significantly when adjunct classical homeopathic treatment is administered in addition to conventional therapy.
The second study is a little more modest; it had the aim to explore the benefits of a three-month course of individualised homeopathy (IH) for survivors of cancer.
Fifteen survivors of any type of cancer were recruited by a walk-in cancer support centre. Conventional treatment had to have taken place within the last three years. Patients scored their total, physical and emotional wellbeing using the Functional Assessment of Chronic Illness Therapy for Cancer (FACIT-G) before and after receiving four IH sessions.
The results showed that 11 women had statistically positive results for emotional, physical and total wellbeing based on FACIT-G scores.
And the conclusion: Findings support previous research, suggesting CAM or individualised homeopathy could be beneficial for survivors of cancer.
As I said: one has to admire their tenacity, perhaps also their chutzpa – but not their understanding of science or their intelligence. If they were able to think critically, they could only arrive at one conclusion: STUDY DESIGNS THAT ARE WIDE OPEN TO BIAS ARE LIKELY TO DELIVER BIASED RESULTS.
The second study is a mere observation without a control group. The reported outcomes could be due to placebo, expectation, extra attention or social desirability. We obviously need an RCT! But the first study was an RCT!!! Its results are therefore more convincing, aren’t they?
No, not at all. I can repeat my sentence from above: The reported outcomes could be due to placebo, expectation, extra attention or social desirability. And if you don’t believe it, please read what I have posted about the infamous ‘A+B versus B’ trial design (here and here and here and here and here for instance).
My point is that such a study, while looking rigorous to the naïve reader (after all, it’s an RCT!!!), is just as inconclusive when it comes to establishing cause and effect as a simple case series which (almost) everyone knows by now to be utterly useless for that purpose. The fact that the A+B versus B design is nevertheless being used over and over again in alternative medicine for drawing causal conclusions amounts to deceit – and deceit is unethical, as we all know.
My overall conclusion about all this:
QUACKS LOVE THIS STUDY DESIGN BECAUSE IT NEVER FAILS TO PRODUCE FALSE POSITIVE RESULTS.
Not much is known about the interactions of real doctors (by this I mean people who have been to medical school) and chiropractors who like to call themselves ‘doctors’ or ‘DCs’ but have never been to medical school. Therefore this recent article is of particular interest, in my view.
The purpose of this paper was to identify characteristics of Canadian chiropractors (DCs) associated with the number of patients referred by medical doctors (MDs). For this purpose, secondary data analyses were performed on the 2011 cross-sectional survey of the Canadian Chiropractic Resources Databank survey which included 81 questions about the practice of DCs. Of the 6533 mailed questionnaires, 2529 (38.7%) were returned and 489 did not meet our inclusion criteria. In total, the analysed sample included 2040 respondents.
The results show that, on average, DCs reported receiving 15.6 (SD 31.3) patient referrals from MDs per year. Nearly one-third of the respondents did not receive any. The type of clinic (multidisciplinary with MD), the province of practice (Atlantic provinces), the number of treatments provided per week, the number of practicing hours, rehabilitation and sports injuries as the main sector of activity, prescription of exercises, use of heat packs and ultrasound, and the percentage of patients referred to other health care providers were associated with a higher number of MD referrals to DCs. The percentage of patients with somatovisceral conditions, using a particular chiropractic technique (hole in one and Thompson), taking own radiographs, being the client of a chiropractic management service, and considering maintenance/wellness care as a main sector of activity were associated with fewer MD referrals.
The authors concluded that Canadian DCs who interacted with other health care workers and who focus their practice on musculoskeletal conditions reported more referrals from MDs.
One could criticise this survey for a number of reasons, for instance:
- the response rate was low,
- the sample was small,
- the data are now 4 years old and might be obsolete.
Despite these flaws, the paper does seem to reveal some relevant things. What I find especially interesting is that:
- the level of referrals from doctors to chiropractors seems exceedingly low,
- dubious chiropractic activities such as maintenance therapy or treatment of non-spinal conditions led to even less referrals.
To me, that implies that Canadian doctors are, on the one hand, willing to co-operate with chiropractors. On the other hand, they remain cautious about the high level of quackery in this profession.
All this means really is that Canadian doctors are responsible and aim to adhere to evidence-based practice…in contrast to many chiropractors, I hasten to add.
If I tell you that I just read a book by a homeopath writing about homeopathy, would you doubt my sanity? But I did, and I read it in one session with great interest. The book is (in German) by Natalie Grams (perhaps I should mention that I had never heard of her before Springer sent me her book), a German doctor; it is entitled HOMOEOPATHIE NEU GEDACHT (Homeopathy newly considered). I liked it a lot.
The author discusses in some detail why basically everything homeopaths believe in is erroneous. You might think: so what, we all knew that. True, we did, but she then she concludes that homeopathy has still some value as some sort of psychotherapy. The remedy is effective because the consultation with a homeopath gives it a ‘meaning’ which is tailor-made for each patient. Now you will think: that this is hardly original, others have considered this before. And you are, of course, correct again.
So why did this book fascinate me? Mostly because, in a few passages, Natalie Grams tells her very personal story how she matured from an enthusiast to rationalist. This could be reminiscent of my own life, but it isn’t (and by no means do I agree with everything doctor Grams writes). I found myself in a homeopathic hospital directly after medical school, became a homeopath (of sorts), later I learnt to think critically and researched homeopathy. As a scientist, when the evidence was squarely negative, I said so loud and clear (I published the whole story with all the relevant details here).
Natalie Grams studied medicine and seemed to have become disenchanted with the lack of humanity in mainstream medicine (as a clinician, I often felt this too but always concluded that the solution was not to turn away from medicine but to re-introduce more humanity into it). Doctor Grams then experienced serious health problems which were cured/alleviated by homeopathy. This made her look into the subject a little closer. She decided to do the necessary courses, uncritically adopted most of what she was told by die-hard homeopaths and eventually fulfilled her dream: she opened her own private practice as a homeopath. In other words, she dropped out of real medicine and into homeopathy, while I, in a way, did the reverse.
Doctor Grams’ practice seemed to have been successful; many of her patients, even some with serious conditions, got better. All she had been told about homeopathy seemed to get confirmed in her clinical routine. Homeopaths, like most clinicians, remember their success stories and tend to forget their failures. If this happens over and over during an entire life-time, the last doubts a budding homeopath may have once had dissolve into thin air. The result is a clinician who is utterly convinced that like cures like and high dilutions are powerful medicines because water has a memory.
Up to this point, Dr Grams career is a textbook example of a homeopath who would bet on the life of her children that homeopathy is correct and science is wrong. The world is full of them, and I have personally met many. They are usually kind, empathetic and dedicated clinicians. But they are also totally impervious to reason. They have their experience and NOBODY is allowed to question it. If you do, you are no longer their friend.
This is where the typical story of homeopaths ends… and they happily lied ever after (to themselves, their patients and everyone else). Not so in the case of Natalie Grams!
When she was still an enthusiast, she decided to write a book. It was going to be a book that showed how good homeopathy was and how bad its critics were. To do this responsibly, she read a lot of the original literature. What she found shocked her. When reading her account, I could repeatedly feel the agony she must have felt through her discoveries. Eventually, she had no choice but to agree with most of the arguments of homeopathy’s critics and disagreed with practically all of the arguments of her fellow homeopaths.
I predict that Natalie’s painful ‘journey’ has not yet come to an end; she now argues that the 200 year old assumptions of homeopathy are all obsolete and homeopathy is certainly not an effective drug therapy. However, it may turn out to be a valuable ‘talking therapy’, she believes.
I hate to say it, but I am fairly certain that she will have to go through further agony and find that her discovery is not truly workable. It might have some theoretical value but, for a whole number of reasons, it will not function in real life heath care.
My hope is that Natalie will find her way back to what she calls ‘normal medicine’ (there is, of course, the danger that she does the opposite and wanders off into even more esoteric grounds). We need doctors like her who have empathy, compassion and understanding for their patients. These are qualities many homeopaths who I have met have in abundance – but these are qualities that belong not into the realm of quackery, they belong into real medicine.
Time for some fun!
In alternative medicine, there often seems to be an uneasy uncertainty about research methodology. This is, of course, regrettable, as it can (and often does) lead to misunderstandings.

There are things that cannot be said too often. In medicine, these are often related to issues that can save lives. In alternative medicine, it is worth remembering that there is nothing that can save more lives than the following rule: EVEN AN APPARENTLY HARMLESS REMEDY WILL BECOME LIFE-THREATENING, IF IT IS USED AS AN ALTERNATIVE TO AN EFFECTIVE THERAPY FOR A SERIOUS CONDITION.
Here is a publication that serves as a very sad reminder of this important axiom.
Japanese physicians recently published a case-report of 2-year-old girl who died of precursor B-cell acute lymphoblastic leukaemia (ALL), the most common cancer in children. She had no remarkable medical history. She was transferred to a hospital because of respiratory distress and died 4 hours after arrival.
Two weeks before her death, she had developed a fever of 39°C, which subsided after the administration of a naturopathic herbal remedy. Subsequently, she developed jaundice one week before death, and her condition worsened on the day of death.
Laboratory test results on admission showed a markedly elevated white blood cell count. Accordingly, the cause of death was suspected to be acute leukaemia. Forensic autopsy revealed the cause of death to be precursor B-cell ALL.
With advancements in medical technology, the 5-year survival rate of children with ALL is nearly 90%. However, in this case, the deceased’s parents preferred alternative medicine to evidence-based medicine and had not taken her to a hospital for a medical check-up or immunisation since she was an infant. The authors state that, if she had received routine medical care, she would have a more than 60% chance of being alive 5 years after diagnosis. Therefore, we conclude that the parents should be accused of medical neglect regardless of their motives.
Alternative practitioners who treat their patients in this way, are in my experience often full of good intentions. They remind me of something Bert Brecht one wrote: THE OPPOSITE OF GOOD IS NOT EVIL, IT IS GOOD INTENTIONS.
A recent post of mine prompted this categorical statement by one of the leading alt med researchers in Germany: “naturopathy does not include homeopathy.” This caused several counter-comments claiming that homeopathy is an established part of naturopathy. Now a regular reader has alerted me to the current position paper on homeopathy by the ‘AMERICAN ASSOCIATION OF NATUROPATHIC PHYSICIANS’ (AANP). It clarifies the issue fairly well, and I therefore take the liberty of citing it here in full:
“Overview of Naturopathic Medicine and Homeopathy
Homeopathy has been an integral part of naturopathic medicine since its inception and is a recognized specialty for which the naturopathic profession has created a distinct specialty organization, the Homeopathic Academy of Naturopathic Physicians. Homeopathy has been recognized, through rigorous testing and experimentation, as having significant scientific evidence supporting its efficacy and safety. Single medicines are given on the basis of an individual’s manifestation of a disease state in comparison to combination remedies which are given on the basis of a particular diagnostic category.
Homeopathic products are being subjected to intensified federal regulations and restrictions. Products are being promoted and marketed as “homeopathic” for a variety of uses ranging from weight-loss aids to immunizations. Many of these preparations are not homeopathic and many have not been satisfactorily proven to be efficacious. Homeopathy is practiced in a variety of traditional and non-traditional forms.
Position of the American Association of Naturopathic Physicians:
- Homeopathy is taught in the naturopathic colleges and its practice should be included in the naturopathic licensing laws. Naturopathic physicians recognize other licensed practitioners of the healing arts who are properly trained in homeopathy.
- The naturopathic profession initiates more clinical trials and provings to further evaluate the effectiveness of homeopathy.
- Naturopathic physicians shall be authorized to prescribe and dispense all products included in the Homeopathic Pharmacopoeia of the United States (HPUS).
- Homeopathic products shall be subject to strict labeling requirements. Preparations which are not prepared in accord with the manufacturing principles in the HPUS should not use the term “homeopathic.” If parents choose homeopathic preparations for their children or their wards for the prophylaxis of infectious disease as an alternative to conventional immunizations, the physician should clearly state that they are unproven and that they are not legal substitutes for the state-mandated requirements.
- Homeopathic prescriptions should be made with careful evaluation of their effect on the entire organism.
- Electro-diagnostic testing is an investigational tool. Electro-diagnostic testing should be used according to accepted protocol and it is recommended that it not be relied on as the sole determinant in homeopathic prescribing.”
So, was Prof Michalsen wrong when he stated that “naturopathy does not include homeopathy. It is established in Germany as the application of nutritional therapy, exercise, herbal medicine, balneotherapy and stress reduction, defined by the German Board of Physicians. In conclusion, my general and last suggestion to these kinds of comments and blogs: Please first learn the facts and then comment.”? Not wrong, perhaps – but just a little Teutonic and provincial? The Germans like their own definitions which do not apply to the rest of the world. Nothing wrong with that, I think. But, in this case, they should make it clear that they are talking about something else than the international standard, and perhaps they should also publish their national drivel in their provincial journals in German language. This would avoid all sorts of misunderstandings, I am sure.
But this may just be a trivial aside. The more interesting issue here is the above AANP-statement itself. The AANP has the following vision: “Naturopathic physicians will guide and empower people to discover and experience improved health, optimal wellness, and effective management of disease through the principles and practices of naturopathic medicine.”
These are very nice words; but they are just that: WORDS. The AANP clearly does not believe in their own vision. If they did, they could never speak of ‘EFFECTIVE MANAGEMENT OF DISEASE’ while condoning the use of therapies that have been shown to be ineffective.
And this is where, in my view, the importance of their ‘position paper’ really lies: it demonstrates once again that, in the realm of alternative medicine, organisations and individuals make statements that sound fine and are politically correct, while at the same time disregarding these pompous aims/visions/objectives by promoting outright quackery. This sort of thing is so wide-spread that most of us just take it for granted and very few have the nerve to object. The result of this collective behaviour is obvious: on the one hand, charlatans can claim to be entirely in line with public health, EBM etc.; on the other hand, they are free to exploit the public with their bogus treatments.
Could this be the true common denominator of naturopathy in Germany and the rest of the world?
A recent comment to a post of mine (by a well-known and experienced German alt med researcher) made the following bold statement aimed directly at me and at my apparent lack of understanding research methodology:
C´mon , as researcher you should know the difference between efficacy and effectiveness. This is pharmacological basic knowledge. Specific (efficacy) + nonspecific effects = effectiveness. And, in fact, everything can be effective – because of non-specific or placebo-like effects. That does not mean that efficacy is existent.
The point he wanted to make is that outcome studies – studies without a control group where the researcher simply observe the outcome of a particular treatment in a ‘real life’ situation – suffice to demonstrate the effectiveness of therapeutic interventions. This belief is very wide-spread in alternative medicine and tends to mislead all concerned. It is therefore worth re-visiting this issue here in an attempt to create some clarity.
When a patient’s condition improves after receiving a therapy, it is very tempting to feel that this improvement reflects the effectiveness of the intervention (as the researcher mentioned above obviously does). Tempting but wrong: there are many other factors involved as well, for instance:
- the placebo effect (mainly based on conditioning and expectation),
- the therapeutic relationship with the clinician (empathy, compassion etc.),
- the regression towards the mean (outliers tend to return to the mean value),
- the natural history of the patient’s condition (most conditions get better even without treatment),
- social desirability (patients tend to say they are better to please their friendly clinician),
- concomitant treatments (patients often use treatments other than the prescribed one without telling their clinician).
So, how does this fit into the statement above ‘Specific (efficacy) + nonspecific effects = effectiveness’? Even if this formula were correct, it would not mean that outcome studies of the nature described demonstrate the effectiveness of a therapy. It all depends, of course, on what we call ‘non-specific’ effects. We all agree that placebo-effects belong to this category. Probably, most experts also would include the therapeutic relationship and the regression towards the mean under this umbrella. But the last three points from my list are clearly not non-specific effects of the therapy; they are therapy-independent determinants of the clinical outcome.
The most important factor here is usually the natural history of the disease. Some people find it hard to imagine what this term actually means. Here is a little joke which, I hope, will make its meaning clear and memorable.
CONVERATION BETWEEN TWO HOSPITAL DOCTORS:
Doc A: The patient from room 12 is much better today.
Doc B: Yes, we stared his treatment just in time; a day later and he would have been cured without it!
I am sure that most of my readers now understand (and never forget) that clinical improvement cannot be equated with the effectiveness of the treatment administered (they might thus be immune to the misleading messages they are constantly exposed to). Yet, I am not at all sure that all ‘alternativists’ have got it.
