In my last post and several others before, I have stated that consumers are incessantly being mislead about the value of alternative medicine. This statement requires evidence, and I intend to provide it – not just in one post but in a series of posts following in fast succession.
I start with an investigation we did over a decade ago. Its primary aim was to determine which complementary therapies are believed by their respective representing UK professional organizations to be suited for which medical conditions.
For this purpose, we sent out 223 questionnaires to CAM organizations representing a single CAM therapy (yes, amazingly that many such institutions exist just in the UK!). They were asked to list the 15 conditions which they felt benefited most from their specific CAM therapy, as well as the 15 most important contra-indications, the typical costs of initial and any subsequent treatments and the average length of training required to become a fully qualified practitioner. The conditions and contra-indications quoted by responding CAM organizations were recorded and the top five of each were determined. Treatment costs and hours of training were expressed as ranges.
Only 66 questionnaires were returned. Taking undelivered questionnaires into account, the response rate was 34%. Two or more responses were received from CAM organizations representing twelve therapies: aromatherapy, Bach flower remedies, Bowen technique, chiropractic, homoeopathy, hypnotherapy, magnet therapy, massage, nutrition, reflexology, Reiki and yoga.
The top seven common conditions deemed to benefit from all twelve therapies, in order of frequency, were: stress/anxiety, headaches/migraine, back pain, respiratory problems (including asthma), insomnia, cardiovascular problems and musculoskeletal problems. It is perhaps important at this stage to point out that some of these conditions are serious, even life-threatening. Aromatherapy, Bach flower remedies, hypnotherapy, massage, nutrition, reflexology, Reiki and yoga were all recommended as suitable treatments for stress/anxiety. Aromatherapy, Bowen technique, chiropractic, hypnotherapy, massage, nutrition, reflexology, Reiki and yoga were all recommended for headache/migraine. Bowen technique, chiropractic, magnet therapy, massage, reflexology and yoga were recommended for back pain. None of the therapies cost more than £60 for an initial consultation and treatment. No correlation between length of training and treatment cost was noted.
I think, this article provides ample evidence to show that, at least in the UK, professional organisations of alternative medicine readily issue statements about the effectiveness of specific alternative therapies which are not supported by evidence. Several years later, Simon Singh noted that phenomenon in a Guardian-comment and wrote about the British Chiropractic Association “they happily promote bogus claims”. He was famously sued for libel but won the case. Simon had picked the BCA merely by chance. The frightening thought is that he could have targeted any other of the 66 organisations from our investigation: they all seem to promote bogus claims quite happily.
Several findings from our study stood out for being particularly worrying: according to the respective professional organisation, Bach Flower Remedies were deemed to be effective for cancer and AIDS, for instance. If their peers put out such irresponsible nonsense, we should not be amazed at the claims made by the practitioners. And if the practitioners tell such ‘tall tales’ to their clients, to journalists and to everyone else, how can we be amazed that we seem to be drowning in a sea of misinformation?
Quite a few people seem to be amazed about the amount of work and the enthusiasm I invest into this blog. To be honest, I am amazed too. Why do I do it? And why do I do it in the way I do it?
I am sure that my critics have a choice of answers at the ready; in one way or another, the following theories have been put forward:
- I was bought by the pharmaceutical industry.
- I have had a bad experience with one or several alternative practitioners.
- I want to get rich and/or famous.
- I feel that conventional medicine is flawless
- I don’t know what I am writing about.
None of these notions is remotely true, of course.
Big Pharma has never approached me, and so far nobody at all has ever tried to influence the contents of my posts. I never had a bad personal experience with alternative medicine; on the contrary, I had several quite positive ones. The blog does not earn me money; it even costs a little to run it, and nobody other than I pay for it. I do not think that fame is something one can achieve through doing a blog, and I certainly do not aim at doing so. Sadly, I know only too well about the many flaws in conventional medicine; it is often far from perfect but at least it makes progress; alternative medicine, by contrast, seems almost entirely static. As I have studied most aspects of alternative medicine for two decades and published more than any other person on this subject, I think the allegation of incompetence might be a bit far-fetched.
So, why then?
When I decided to become a doctor I, like most medical students, did so mainly to help suffering individuals. When I became a researcher, I felt more removed from this original ideal. Yet I told myself that, by conducting research, I might eventually contribute to a better health care of tomorrow. Helping suffering patients was still firmly on the agenda. But then I realised that my articles in peer-reviewed medical journals somehow missed an important target: in alternative medicine, one ought to speak not just to health care professionals but also to consumers and patients; after all, it is they who often make the therapeutic decisions in this area.
Once I had realised this, I started addressing the general public by writing for The Guardian and other newspapers, giving public lectures and publishing books for a lay audience, like TRICK OR TREATMENT…The more I did this sort of thing, the more I noticed how important this activity was. And when a friend offered to help me set up a blog, I did not hesitate for long.
So, the reason for my enthusiasm for this blog turns out to be the same as the one that enticed me to go into medicine in the first place. I do believe that it is helpful for consumers to know the truth about alternative medicine. Considering the thousands of sources of daily misinformation in this area, there is an urgent need for well-informed, critical information. By providing it, I am sure I can assist people to make better therapeutic decisions. In a way, I am back where I started all those years ago: hoping to help suffering patients in the most direct way my expertise allows.
Realgar, a commonly used traditional Chinese medicine, has – according to the teachings of Traditional Chinese Medicine (TCM) – acrid, bitter, warm, and toxic characteristics and is affiliated with the Heart, Liver and Stomach meridians. It is used internally against intestinal parasites and treat sore throats, and is applied externally to treat swelling, abscesses, itching, rashes, and other skin disorders.
Chemically, it is nothing other than arsenic sulphide. Despite its very well-known toxicity, is thought by TCM-practitioners to be safe, and it has been used in TCM under the name ‘Xiong Huang’ for many centuries. TCM-practitioners advise that the typical internal dose of realgar is between 0.2 and 0.4 grams, decocted in water and taken up to two times per day. Some practitioners may recommend slightly higher doses (0.3-0.9 grams). Larger doses of realgar may be used if it is being applied topically.
Toxicologists from Taiwan report a case of fatal realgar poisoning after short-term use of a topical realgar-containing herbal medicine.
A 24-year-old man with atopic dermatitis had received 18 days of oral herbal medicine and realgar-containing herbal ointments over whole body from a TCM-practitioner. Seven days later, he started to develop loss of appetite, dizziness, abdominal discomfort, an itching rash and skin scaling. Subsequently he suffered generalized oedema, nausea, vomiting, decreased urine amount, diarrhoea, vesico-oedematous exanthemas, malodorous perspiration, fever, and shortness of breath.
He was taken to hospital on day 19 when the dyspnoea became worse. Toxic epidermal necrolysis complicated with soft tissue infection and sepsis were then diagnosed. The patient died shortly afterwards of septic shock and multiple organ failure. Post-mortem blood arsenic levels were elevated at 1225 μg/L. The analysis of the patient’s herbal remedies yielded a very high concentration of arsenic in three unlabelled realgar-containing ointments (45427, 5512, and 4229 ppm).
The authors of this report concluded that realgar-containing herbal remedy may cause severe cutaneous adverse reactions. The arsenic in realgar can be absorbed systemically from repeated application to non-intact skin and thus should not be extensively used on compromised skin.
The notion that a treatment that ‘has stood the test of time’ must be safe and effective is very wide-spread in alternative medicine. This, we often hear, applies particularly to the external use of traditional remedies – what can be wrong with putting a traditional Chinese herbal cream on the skin?? This case, like so many others, should teach us that this appeal to tradition is a classical and often dangerous fallacy. And the ‘realgar-story’ also suggests that, in TCM, the ‘learning-curve’ is very flat indeed.
Chinese and Ayurvedic remedies are often contaminated with toxic heavy metals. But the bigger danger seems to be that some of these traditional ‘medicines’ contain such toxins because, according to ‘traditional wisdom’, these constituents have curative powers. I think that, until we have compelling evidence that any of these treatments do more good than harm, we should avoid taking them.
Can one design a clinical study in such a way that it looks highly scientific but, at the same time, has zero chances of generating a finding that the investigators do not want? In other words, can one create false positive findings at will and get away with it? I think it is possible; what is more, I believe that, in alternative medicine, this sort of thing happens all the time. Let me show you how it is done; four main points usually suffice:
- The first rule is that it ought to be an RCT, if not, critics will say the result was due to selection bias. Only RCTs have the reputation of being ‘top notch’.
- Once we are clear about this design feature, we need to define the patient population. Here the trick is to select individuals with an illness that cannot be quantified objectively. Depression, stress, fatigue…the choice is vast. The aim must be to employ an outcome measure that is well-accepted, validated etc. but which nevertheless is entirely subjective.
- Now we need to consider the treatment to be “tested” in our study. Obviously we take the one we are fond of and want to “prove”. It helps tremendously, if this intervention has an exotic name and involves some exotic activity; this raises our patients’ expectations which will affect the result. And it is important that the treatment is a pleasant experience; patients must like it. Finally it should involve not just one but several sessions in which the patient can be persuaded that our treatment is the best thing since sliced bread – even if, in fact, it is entirely bogus.
- We also need to make sure that, for our particular therapy, no universally accepted placebo exists which would allow patient-blinding. That would be fairly disastrous. And we certainly do not want to be innovative and create such a placebo either; we just pretend that controlling for placebo-effects is impossible or undesirable. By far the best solution would be to give the control group no treatment at all. Like this, they are bound to be disappointed for missing out a pleasant experience which, in turn, will contribute to unfavourable outcomes in the control group. This little trick will, of course, make the results in the experimental group look even better.
That’s about it! No matter how ineffective our treatment is, there is no conceivable way our study can generate a negative result; we are in the pink!
Now we only need to run the trial and publish the positive results. It might be advisable to recruit several co-authors for the publication – that looks more serious and is not too difficult: people are only too keen to prolong their publication-list. And we might want to publish our study in one of the many CAM-journals that are not too critical, as long as the result is positive.
Once our article is in print, we can legitimately claim that our bogus treatment is evidence-based. With a bit of luck, other research groups will proceed in the same way and soon we will have not just one but several positive studies. If not, we need to do two or three more trials along the same lines. The aim is to eventually do a meta-analysis that yields a convincingly positive verdict on our phony intervention.
You might think that I am exaggerating beyond measure. Perhaps a bit, I admit, but I am not all that far from the truth, believe me. You want proof? What about this one?
Researchers from the Charite in Berlin just published an RCT to investigate the effectiveness of a mindful walking program in patients with high levels of perceived psychological distress.
To prevent allegations of exaggeration, selective reporting, spin etc. I take the liberty of reproducing the abstract of this study unaltered:
Participants aged between 18 and 65 years with moderate to high levels of perceived psychological distress were randomized to 8 sessions of mindful walking in 4 weeks (each 40 minutes walking, 10 minutes mindful walking, 10 minutes discussion) or to no study intervention (waiting group). Primary outcome parameter was the difference to baseline on Cohen’s Perceived Stress Scale (CPSS) after 4 weeks between intervention and control.
Seventy-four participants were randomized in the study; 36 (32 female, 52.3 ± 8.6 years) were allocated to the intervention and 38 (35 female, 49.5 ± 8.8 years) to the control group. Adjusted CPSS differences after 4 weeks were -8.8 [95% CI: -10.8; -6.8] (mean 24.2 [22.2; 26.2]) in the intervention group and -1.0 [-2.9; 0.9] (mean 32.0 [30.1; 33.9]) in the control group, resulting in a highly significant group difference (P < 0.001).
Conclusion. Patients participating in a mindful walking program showed reduced psychological stress symptoms and improved quality of life compared to no study intervention. Further studies should include an active treatment group and a long-term follow-up
This whole thing could just be a bit of innocent fun, but I am afraid it is neither innocent nor fun, it is, in fact, quite serious. If we accept manipulated trials as evidence, we do a disservice to science, medicine and, most importantly, to patients. If the result of a trial is knowable before the study has even started, it is unethical to run the study. If the trial is not a true test but a simple promotional exercise, research degenerates into a farcical pseudo-science. If we abuse our patients’ willingness to participate in research, we jeopardise more serious investigations for the benefit of us all. If we misuse the scarce funds available for research, we will not have the money to conduct much needed investigations. If we tarnish the reputation of clinical research, we hinder progress.
“Wer heilt hat recht”. Every German knows this saying and far too many believe it. Literally translated, it means THE ONE WHO HEALS IS RIGHT, and indicates that, in health care, the proof of efficacy of a treatment is self-evident: if a clinician administers a treatment and the patient improves, she was right in prescribing it and the treatment must have been efficacious. The only English saying which is vaguely similar (but rarely used for therapies) is THE PROOF OF THE PUDDING IS IN THE EATING, translated into a medical context: the proof of the treatment is in the clinical outcome.
The saying is German but the sentiment behind it is amazingly widespread across the world, particularly the alternative one. If I had a fiver for each time a German journalist has asked me to comment on this ‘argument’ I could probably invite all my readers for a beer in the pub. The notion seems to be irresistibly appealing and journalists, consumers, patients, politicians etc. fall for it like flies. It is popular foremost as a counter-argument against scientists’ objections to homeopathy and similar placebo-treatments. If the homeopath cured her patient, then she and her treatments are evidently fine!
It is time, I think, that I scrutinise the argument and refute it once and for all.
The very first thing to note is that placebos never cure a condition. They might alleviate symptoms, but cure? No!
The next issue relates to causality. The saying assumes that the sole reason for the clinical outcome is the treatment. Yet, if a patient’s symptoms improve, the reason might have been the prescribed treatment, but this is just one of a multitude of different options, e.g.:
- the placebo-effect
- the regression towards the mean
- the natural history of the condition
- the Hawthorne effect
- the compassion of the clinician
- other treatments that might have been administered in parallel
Often it is a complex mixture of these and possibly other phenomena that is responsible and, unless we run a proper clinical trial, we cannot even guess the relative importance of each factor. To claim in such a messy situation that the treatment given by the clinician was the cause of the improvement, is ridiculously simplistic and overtly wrong.
But that is precisely what the saying WER HEILT HAT RECHT does. It assumes a simple mono-causal relationship that never exists in clinical settings. And, annoyingly, it somewhat arrogantly dismisses any scientific evidence by implying that the anecdotal observation is so much more accurate and relevant.
The true monstrosity of the saying can be easily disclosed with a little thought experiment. Let’s assume the saying is correct and we adopt it as a major axiom in health care. This would have all sorts of terrible consequences. For instance, any pharmaceutical company would be allowed to produce colourful placebos and sell them for a premium; they would only need to show that some patients do experience some relief after taking it. THE ONE WHO HEALS IS RIGHT!
The saying is a dangerously misleading platitude. That it happens to be German and that the Germans remain so frightfully fond of it disturbs me. That the notion, in one way or another, is deeply ingrained in the mind of charlatans across the world is worrying but hardly surprising – after all, it is said to have been coined by Samuel Hahnemann.
One of the most gratifying aspect of my work in Exeter was being able to offer posts to visiting researchers from across the world. Some of these co-workers, after returning to their home countries, became prominent scientists in their own right, and quite a few remained in contact and continued to collaborate with me or with members of my team. In one of these collaborative projects, we wanted to investigate adverse events attributed to traditional medical treatments in the Republic of Korea.
For this purpose, we reviewed adverse events recorded in the Republic of Korea, between 1999 and 2010, by the Food and Drug Administration, the Consumer Agency or the Association of Traditional Korean Medicine. Records of adverse events attributed to the use of traditional medical practices, including reports of medicinal accidents and consumers’ complaints, were evaluated.
Overall, 9624 records of adverse events were identified. Liver problems after the administration of herbal medicines were the most frequently reported adverse events. Only eight of the adverse events were recorded by the pharmacovigilance system run by the Food and Drug Administration. Of the 9624 events, 1389 – mostly infections, cases of pneumothorax and burns – were linked to physical therapies (n = 285) or acupuncture/moxibustion (n = 1104).
We concluded that traditional medical practices often appear to have adverse effects, yet almost all of the adverse events attributed to such practices between 1999 and 2010 were missed by the national pharmacovigilance system. The Consumer Agency and the Association of Traditional Korean Medicine should be included in the national pharmacovigilance system.
The assumption that alternative treatments are entirely harmless is widespread, not least because it is incessantly promoted via millions of web-site, thousands of books, newspaper articles, VIPs like Prince Charles etc. etc. Consumers are incessantly being told that NATURAL = SAFE. Yet, if we look closely, most alternative treatments are not natural and, as this investigation demonstrates, they are certainly not devoid of risks.
I already see the apologists preparing to comment that, compared to conventional therapies, alternative treatments are very safe. So let me pre-empt this fallacy by pointing out (yet again) that 1) in the absence of adequate surveillance systems, nobody can say how frequent adverse-effects of alternative treatments really are, and that 2) even severe adverse effects can normally be tolerated, if the treatment in question has been shown to be efficacious.
So, instead of commenting on my repeated reports about the risks of alternative medicine, I invite, in fact, I challenge my critics to answer this simple question: For how many alternative therapies is there a well-documented positive risk/benefit balance?
A lengthy article posted by THE HOMEOPATHIC COLLEGE recently advocated treating cancer with homeopathy. Since I doubt that many readers access this publication, I take the liberty of reproducing here their (also fairly lengthy) CONCLUSIONS in full:
Laboratory studies in vitro and in vivo show that homeopathic drugs, in addition to having the capacity to reduce the size of tumors and to induce apoptosis, can induce protective and restorative effects. Additionally homeopathic treatment has shown effects when used as a complementary therapy for the effects of conventional cancer treatment. This confirms observations from our own clinical experience as well as that of others that when suitable remedies are selected according to individual indications as well as according to pathology and to cell-line indications and administered in the appropriate doses according to the standard principles of homeopathic posology, homeopathic treatment of cancer can be a highly effective therapy for all kinds of cancers and leukemia as well as for the harmful side effects of conventional treatment. More research is needed to corroborate these clinical observations.
Homeopathy over almost two decades of its existence has developed more than four hundred remedies for cancer treatment. Only a small fraction have been subjected to scientific study so far. More homeopathic remedies need to be studied to establish if they have any significant action in cancer. Undoubtedly the next big step in homeopathic cancer research must be multiple comprehensive double-blinded, placebo-controlled, randomized clinical trials. To assess the effect of homeopathic treatment in clinical settings, volunteer adult patients who prefer to try homeopathic treatment instead of conventional therapy could be recruited, especially in cases for which no conventional therapy has been shown to be effective.
Many of the researchers conducting studies — cited here but not discussed — on the growing interest in homeopathic cancer treatment have observed that patients are driving the demand for access to homeopathic and other alternative modes of cancer treatment. So long as existing cancer treatment is fraught with danger and low efficacy, it is urgent that the research on and the provision of quality homeopathic cancer treatment be made available for those who wish to try it.
When I report about nonsense like that, I find it hard not to go into a fuming rage. But doing that would not be very constructive – so let me instead highlight (in random order) eight simple techniques that seem to be so common when unsubstantiated claims are being promoted for alternative treatments:
1) cherry pick the data
2) use all sorts of ‘evidence’ regardless how flimsy or irrelevant it might be
3) give yourself the flair of being highly scientific and totally impartial
4) point out how dangerous and ineffective all the conventional treatments are
5) do not shy away from overt lies
6) do not forget to stress that the science is in full agreement with your exhaustive clinical experience
7) stress that patients want what you are offering
8) ignore the biological plausibility of the underlying concepts
Provided we adhere to these simple rules, we can convince the unsuspecting public of just about anything – even of the notion that homeopathy is a cure for cancer!
In Europe, we have chiropractors, homeopaths, naturopaths and anthroposophical physicians who recommend to their patients not to vaccinate their children. In the US, they have all this plus some of the clergy to jeopardize herd immunity.
An outbreak of measles infections has been reported in Tarrant County, Texas, US where at least 21 people have been affected this month at the Eagle Mountain International Church. The ministers of this church have been critical of vaccination and advised to use alternative treatments. Several more cases of infections with fever and rash have been noted, but so far remain unconfirmed.
Before the measles vaccine was introduced in 1963, between 3 million and 4 million people in the U.S. were infected each year, 48,000 of them needed hospitalisation and 400 to 500 died. Another 1,000 developed chronic disabilities. In the US measles were considered eradicated in 2000, but outbreaks continue because of imported infections brought back by travellers from areas where measles remains common.
The Texas outbreak was caused by a non-vaccinated visitor who had been infected in Indonesia and then returned to expose unvaccinated church members, staff and children in a day-care centre. In the wider community, more than 98 per cent of kids are immunized and less than 1 per cent are exempt. But the congregation of unvaccinated people allowed the disease to catch hold. Church leaders, including Kenneth Copeland and his daughter, Terri Pearsons, senior pastor at Eagle Mountain, have advocated faith-healing and questioned vaccines in the past.
And what can faith-healing achieve? Where is the evidence that it prevents or cures infections or any other diseases? You probably guessed: there is none.
If one spends a lot of time, as I presently do, sorting out old files, books, journals etc., one is bound to come across plenty of weird and unusual things. I for one, am slow at making progress with this task, mainly because I often start reading the material that is in front of me. It was one of those occasions that I had begun studying a book written by one of the more fanatic proponent of alternative medicine and stumbled over the term THE PROOF OF EXPERIENCE. It made me think, and I began to realise that the notion behind these four words is quite characteristic of the field of alternative health care.
When I studied medicine, in the 1970s, we were told by our peers what to do, which treatments worked for which conditions and why. They had all the experience and we, by definition, had none. Experience seemed synonymous with proof. Nobody dared to doubt the word of ‘the boss’. We were educated, I now realise, in the age of EMINENCE-BASED MEDICINE.
All of this gradually changed when the concepts of EVIDENCE-BASED MEDICINE became appreciated and generally adopted by responsible health care professionals. If now the woman or man on top of the medical ‘pecking order’ claims something that is doubtful in view of the published evidence, it is possible (sometimes even desirable) to say so – no matter how junior the doubter happened to be. As a result, medicine has thus changed for ever: progress is no longer made funeral by funeral [of the bosses] but new evidence is much more swiftly translated into clinical practice.
Don’t get me wrong, EVIDENCE-BASED MEDICINE does not does not imply disrespect EXPERIENCE; it merely takes it for what it is. And when EVIDENCE and EXPERIENCE fail to agree with each other, we have to take a deep breath, think hard and try to do something about it. Depending on the specific situation, this might involve further study or at least an acknowledgement of a degree of uncertainty. The tension between EXPERIENCE and EVIDENCE often is the impetus for making progress. The winner in this often complex story is the patient: she will receive a therapy which, according to the best available EVIDENCE and careful consideration of the EXPERIENCE, is best for her.
NOT SO IN ALTERNATIVE MEDICINE!!! Here EXPERIENCE still trumps EVIDENCE any time, and there is no need for acknowledging uncertainty: EXPERIENCE = proof!!!
In case you think I am exaggerating, I recommend thumbing through a few books on the subject. As I already stated, I have done this quite a bit in recent months, and I can assure you that there is very little evidence in these volumes to suggest that data, research, science, etc.. matter a hoot. No critical thinking is required, as long as we have EXPERIENCE on our side!
‘THE PROOF OF EXPERIENCE’ is still a motto that seems to be everywhere in alternative medicine. In many ways, it seems to me, this motto symbolises much of what is wrong with alternative medicine and the mind-set of its proponents. Often, the EXPERIENCE is in sharp contrast to the EVIDENCE. But this little detail does not seem to irritate anyone. Apologists of alternative medicine stubbornly ignore such contradictions. In the rare case where they do comment at all, the gist of their response normally is that EXPERIENCE is much more relevant than EVIDENCE. After all, EXPERIENCE is based on hundreds of years and thousands of ‘real-life’ cases, while EVIDENCE is artificial and based on just a few patients.
As far as I can see, nobody in alternative medicine pays more than a lip service to the fact that EXPERIENCE can be [and often is] grossly misleading. Little or no acknowledgement exists of the fact that, in clinical routine, there are simply far too many factors that interfere with our memories, impressions, observations and conclusions. If a patient gets better after receiving a therapy, she might have improved for a dozen reasons which are unrelated to the treatment per se. And if a patient does not get better, she might not come back at all, and the practitioner’s memory will therefore fail register such events as therapeutic failures. Whatever EXPERIENCE is, in health care, it rarely constitutes proof!
The notion of THE PROOF OF EXPERIENCE, it thus turns out, is little more than self-serving, wishful thinking which characterises the backward attitude that seems to be so remarkably prevalent in alternative medicine. No tension between EXPERIENCE and EVIDENCE is noticeable because the EVIDENCE is being ignored; as a result, there is no progress. The looser is, of course, the patient: she will receive a treatment based on criteria which are less than reliable.
Isn’t it time to burry the fallacy of THE PROOF OF EXPERIENCE once and for all?
A single, tiny mosquito can make my life a misery. It can rob me of a night’s sleep and turn me into a frantic lunatic. But now there is a remedy that, according to its manufacturer, makes my mosquito-phobia a distant memory. Mosquito-maniacs like myself can finally breathe a sigh of relief!
According to the manufacturer’s web-site, Mozi-Q is formula to reduce the frequency of bites as well as the reactions that people have to bites. No more itching and big red bumps! No more smelly sprays or stinky coils…what a great ally for camping, golfing, hiking, biking. This could revolutionize the whole outdoor experience! Some of the product’s features include:
- It works within 30 minutes of taking it.
- There are no side effects.
- It works on other bugs aside from mosquitoes like ticks and head lice.
- Product can be taken every 3-5 hours starting right before you go outside.
- There are no contraindications.
- Homeopathic medicine is by definition non-toxic…
Mozi-Q is a formula containing five homeopathic remedies:
- Ledum palustre
- Urtica urens
They are in low C and D potencies, thereby acting at the physical level for their common indication, to reduce the frequency and severity of insect bites….
I am sure that most readers will, by now, ask themselves: is there any good evidence for these claims? The manufacturer’s site is pretty affirmative:
In the ’60s a homeopath by the name of HR. Trexler studied Staphysagria for its effectiveness at preventing mosquito bites. In a study of 421 subjects over a 4 year period, he found this remedy to be 90% effective…We have tested this remedy in our clinic over four mosquito seasons and found the response from the public confirmatory of Trexler’s findings.
Sounds great? Yes, but it turns out that the Trexler trial did not test the mixture contained in Mozi-Q at all; it used just one of its ingredients. Moreover, it seemed to have lacked a control group and therefore constitutes no reliable evidence. And the manufacturer’s own tests? I don’t know, they tell us nothing about them.
At this stage, the mosquito-phobe is disappointed. It seems to me that this product is not supported by sound evidence – more trick than treatment.
And why would this important? Because some people like me might lose a bit of sleep? No! It is important because mosquitos, ticks and other insects transmit diseases, some of which can be deadly. If someone claims that there is a preparation which protects us from insect-bites, some consumers will inevitably trust this claim. And this would not just be unfortunate; it could be life-threatening.
