I just came across this hilarious yet revealing article by Italian authors defending homeopathy. It is far too remarkable to keep it for myself, and I therefore decided to quote its abstract here in full:
Throughout its over 200-year history, homeopathy has been proven effective in treating diseases for which conventional medicine has little to offer. However, given its low cost, homeopathy has always represented a serious challenge and a constant threat to the profits of drug companies. Moreover, since drug companies represent the most relevant source of funding for biomedical research worldwide, they are in a privileged position to finance detractive campaigns against homeopathy by manipulating the media as well as academic institutions and the medical establishment. The basic argument against homeopathy is that in some controlled clinical trials (CCTs), comparison with conventional treatments shows that its effects are not superior to those of placebo. Against this thesis we argue that a) CCT methodology cannot be applied to homeopathy, b) misconduct and fraud are common in CCTs, c) adverse drug reactions and side effects show that CCT methodology is deeply flawed, d) an accurate testing of homeopathic remedies requires more sophisticated techniques, e) the placebo effect is no more “plausible” than homeopathy, and its real nature is still unexplained, and f) the placebo effect is nevertheless a “cure” and, as such, worthy of further investigation and analysis. It is concluded that no arguments presently exist against homeopathy and that the recurrent campaigns against it represent the specific interests of the pharmaceutical industry which, in this way, strives to protect its profits from the “threat” of a safer, more effective, and much less expensive treatment modality.
Despite (or is it because?) of such nonsense, homeopathy seems to be very popular, especially in the treatment of small children, and particularly for conditions where conventional medicine has no effective treatment. Teething problems are thus an ideal target for the homeopathic industry.
A survey of British GPs found that the most frequently prescribed homeopathic remedies were for common self-limiting infantile conditions such as colic, cuts and bruises, and teething. Similarly, the Avon-study suggested that homeopathic Chamomillia is popular to alleviate the pain of teething. And prominent homeopaths recommend that “teething often responds to Chamomilla.“
One website also recommends Chamomilla as well as several other homeopathic remedies leaving little doubt about their efficacy:
Chamomilla 6c: When teething is very painful and the child becomes quite cranky, satisfied with nothing and pacified only by being carried, then Chamomilla may help. Sometimes, the child seeking some relief from the discomfort will demand one thing after another, rejecting each one when it does not give relief. Children who could benefit from this remedy are very irritable, with a cry that sounds as if they are in pain. Chamomilla 6c can be taken every thirty minutes, up to six times per day, while symptoms persist.
Mercurius sol 6c: This remedy may be of help in cases where teething is accompanied by excessive salivation and drooling. In addition, the gums are likely to be red and sore, and the child may have diarrhea with a foul smell to it. Mercurius sol 6c can be taken four to six times per day for two to three days; its use should be discontinued when the symptoms diminish.
>Belladonna 30c: For children who tend to develop a fever with a flushed, red face when they are cutting teeth, Belladonna may be a good choice. Often the eyes have a glassy look due to the dilation of the pupils. The child may be irritable and crying as if angry. Belladonna 30c can be taken every thirty minutes up to four times per day, while symptoms continue.
Aconite napellus 30c: When the symptoms come on quickly and include physical and mental restlessness, this remedy may be useful. The affected gums will be hot, swollen, and inflamed and there may also be an earache with aversion to loud noises. The condition may come on following exposure to cold, dry winds. Try Aconite napellus 30c every hour for up to six times per day.
Calcarea carbonica 6c: When children are finally cutting teeth that have been late in erupting, Calcarea carbonica could be helpful. This remedy is often helpful with “late bloomers,” babies who develop a little more slowly, crawling, walking, and cutting teeth on their own schedule, weeks or months later than some other babies or toddlers. Children likely to benefit from Calcarea carbonica often have sweaty heads and feet and may have a tendency to develop cradle cap or yeast infections. With teething, they often do not show the extreme irritability that calls for Chamomilla, or the fever that indicates Belladonna, but they may have teeth that seem permanently on the verge of breaking through the surface. Calcarea carbonica 6c can be taken three times per day, for up to ten days; its use should be discontinued when symptoms improve.
Given this level of assurance, it not really surprising that manufacturers of homeopathic remedies want to profit from all this. Anxious mothers must seem like sitting ducks to the homeopathic industry.
Camilia, a homeopathic teething remedy that contains Chamomillia in the 9c potency from Boiron, the world’s largest producer of homeopathic products, will be launched shortly in the UK. The PR-agency in charge of the UK campaign to promote camilia announced that they will focus on a “national awareness drive through earned and paid-for media along with influencer engagement.” The agency is also responsible for re-building the brand’s website and implementing a strategy to drive discovery online. Amanda Meyrick of Clarion Communications, said: “Launching a product into a new market gives us the opportunity to work in partnership from the beginning to establish Camilia in the UK, and we are looking forward to seeing the results of our planning and creativity.” Remarkably, nobody seems to mention efficacy as a factor in the promotion of camilia.
However, the product is already available in the US, and from the US website we learn that this remedy “temporarily relieves symptoms of teething, including painful gums and irritability.” So, there are clear claims of efficacy after all!
Boiron is not the only firm who aim to profit from the vast market of teething problems. Nelson’s Teetha, for instance, is already available in the UK. Each 300mg sachet of TEETHA contains “the active ingredient of Chamomilla 6c.” Even Boots, the UK’s ‘trusted’ high street pharmacy, sell a product called ‘TEETHING PAIN RELIEF’ which also contains Chamomilla 6c, its only ‘active’ ingredient. Even the name of their product carries a therapeutic claim for efficacy, in my view.
But hold on! A 6c dilution equals one ml of plant extract diluted in 1 000 000 000 litres of water (add 6 zeros to that figure for the Boiron product)!!! Is that really going to alleviate teething problems?
Of course not!, you will say. Dilutions of this nature will do nothing whatsoever.
But they are not just dilutions, they are potentiations! would the homeopaths counter; they have been succussed at each dilution step, and this process transfers a vital force from the Chamomilla extract to the remedy. Yes, of course, how could I forget – it’s homeopathy where LIKE CURES LIKE and people believe in the tooth fairy.
But this does not make any sense either!
Chamomillia is nothing other than chamomile, a plant known to sooth through its anti-inflammatory actions. So, in highly diluted homeopathic products, the actions of this plant should be reversed according to the ‘like cures like’ principle. That means that these teething products, according to homeopathic ‘logic’, is not for treating inflamed gums but for treating the absence of inflammation.
My mind boggles because nothing seems to make sense any more:
- according to real science (or just common sense), the dilutions are far to high to have any effect at all,
- according to homeopathic ‘logic’, these products should, if anything, produce inflammation and not alleviate it,
- according to the best clinical evidence, homeopathic remedies are not effective for teething; I am not aware of a single rigorous trial that would show its efficacy, and current reviews do not recommend homeopathy for teething problems,
- regardless of all this and despite of regulations prohibiting it, therapeutic claims are being made for these over-priced placebos.
IT’S HOMEOPATHY STUPID!
I find it always nice to see that people appreciate my work. Yet sometimes I am a little surprised to realise what some commercially interested firms make of it. Recently I came across a website that proudly used my research for advertising the use of magnetic bracelets against pain. Here is the text in question:
The extra strong magnets make this magnetic bracelet the fastest acting pain reliever. While wearing this magnetic bracelet customers with wrist and hand pain report significant pain relief….
What is a magnetic bracelet and what are the benefits? Magnetic bracelets are a piece of jewelry, worn for the therapeutic benefits of the magnetic field. Magnetic bracelets has been used successfully by many people for pain relief of inflammatory conditions such as arthritis, tendinitis and bursitis.
A randomized, placebo controlled trial with three parallel groups, came to the conclusion : Pain from osteoarthritis of the hip and knee decreases when wearing magnetic bracelets. It is uncertain whether this response is due to specific or non-specific (placebo) effects. Tim Harlow, general practitioner, Colin Greaves, research fellow, Adrian White, senior research fellow, Liz Brown, research assistant, Anna Hart, statistician, Edzard Ernst, professor of complementary medicine.
The entrepreneurs seem to have forgotten a few things which we tried to make clear in our paper:
- this article was published in the Christmas issue of the BMJ which specialises in publishing unusual and odd findings with a high entertainment value,
- in our paper, we point out that “the contamination of group B with stronger magnets prevented a more objective estimation of any-placebo effect”,
- and stressed that “there were problems with the weak magnets”,
- and that “a per-specification analysis suggested (but could not confirm) a specific effect of magnetic bracelets over and above placebo”.
Most importantly, this was just one trial, and surely one swallow does not make a summer! We should always consider the totality of the reliable evidence. Being conscientious researchers, at the time, we did exactly that and conducted a systematic review. Here is the abstract in its full beauty:
Static magnets are marketed with claims of effectiveness for reducing pain, although evidence of scientific principles or biological mechanisms to support such claims is limited. We performed a systematic review and meta-analysis to assess the clinical evidence from randomized trials of static magnets for treating pain.
Systematic literature searches were conducted from inception to March 2007 for the following data sources: MEDLINE, EMBASE, AMED (Allied and Complementary Medicine Database), CINAHL, Scopus, the Cochrane Library and the UK National Research Register. All randomized clinical trials of static magnets for treating pain from any cause were considered. Trials were included only if they involved a placebo control or a weak magnet as the control, with pain as an outcome measure. The mean change in pain, as measured on a 100-mm visual analogue scale, was defined as the primary outcome and was used to assess the difference between static magnets and placebo.
Twenty-nine potentially relevant trials were identified. Nine randomized placebo-controlled trials assessing pain with a visual analogue scale were included in the main meta-analysis; analysis of these trials suggested no significant difference in pain reduction (weighted mean difference [on a 100-mm visual analogue scale] 2.1 mm, 95% confidence interval -1.8 to 5.9 mm, p = 0.29). This result was corroborated by sensitivity analyses excluding trials of acute effects and conditions other than musculoskeletal conditions. Analysis of trials that assessed pain with different scales suggested significant heterogeneity among the trials, which means that pooling these data is unreliable.
The evidence does not support the use of static magnets for pain relief, and therefore magnets cannot be recommended as an effective treatment. For osteoarthritis, the evidence is insufficient to exclude a clinically important benefit, which creates an opportunity for further investigation.
So, would I, on the basis of the current best evidence, recommend magnetic bracelets to people who suffer from pain? No! In my view, only charlatans would do such a thing.
A recent US study found that belief in conspiracy theories is rife in health care. The investigators presented people with 6 different conspiracy theories, and the one that was most widely believed was the following:
THE FOOD AND DRUG ADMINISTRATION IS DELIBERATELY PREVENTING THE PUBLIC FROM GETTING NATURAL CURES FOR CANCER AND OTHER DISEASES BECAUSE OF PRESSURE FROM DRUG COMPANIES.
A total of 37% agreed with this statement, 31% had no opinion on the matter, and 32% disagreed. What is more, the belief in this particular conspiracy correlated positively with the usage of alternative medicine.
Essentially, this implies that the current popularity of alternative medicine is at least partly driven by the conviction that there is a sinister plot by the FDA or more generally speaking ‘the establishment’ that prevents people from benefitting from the wonders of alternative treatments.
I think it was Woody Allen who noted that, just because you are paranoid does not mean that they are not following you. So, let’s look for evidence suggesting that the FDA or any similar organisation is suppressing alternative medicine.
A prime candidate is, of course, the often implicated, thoroughly evil ‘BIG PHARMA‘. I am not a fan of the pharmaceutical industry and I know few people who are. But where is the evidence for BIG PHARMA’s conspiracy against alternative medicine? In the many years of researching this sector, I have never come across a jot of evidence to support this notion. On the contrary, BIG PHARMA seems all to keen to jump on to the alternative bandwagon and make a few quick bucks from the gullibility of the consumer.
What about the rest of the medical establishment? All I see is that universities, hospitals, charities and other organisations in health care currently bend over backwards in order to accommodate as much alternative medicine as they possibly can get away with in view of the often embarrassing lack of convincing evidence for the treatments in question. Conspiracy against alternative medicine? I don’t think so.
The closer we look, the more we arrive at the conclusion that the conspiracy against alternative medicine is a myth and a figment of the imagination of those who religiously believe in alternative medicine. They seem to long for an explanation why their favourite therapy is not in even more wide-spread use. Cognitive dissonance seems to prevent them to consider that the lack of evidence has anything to do with this situation. Consequently, they prefer to invent a conspiracy theory.
And this is where an interesting question emerges, in my view: do people who believe that the FDA or other organisations prevent the public from getting more alternative medicine really need more alternative medicine, or do they perhaps just need an effective treatment for their paranoia?
It is almost 10 years ago that Prof Kathy Sykes’ BBC series entitled ALTERNATIVE MEDICINE was aired. I had been hired by the BBC as their advisor for the programme and had tried my best to iron out the many mistakes that were about to be broadcast. But the scope for corrections turned out to be narrow and, at one stage, the errors seemed too serious and too far beyond repair to continue with my task. I had thus offered my resignation from this post. Fortunately this move led to some of my concerns being addressed after all, and they convinced me to remain in post.
The first part of the series was on acupuncture, and Kathy presented the opening scene of a young women undergoing open heart surgery with the aid of acupuncture. All the BBC had ever shown me and asked me to advise on was the text – I had never seen the images. Kathy’s text included the statement that the patient was having the surgery “with only needles to control the pain.” I had not objected to this statement in the firm belief that the images of the film would back up this extraordinary claim. As it turned out, it did not; the patient clearly had all sorts of other treatments given through intra-venous lines and, in the film, these were openly in the view of Kathy Sykes.
This overt contradiction annoyed not just me but several other people as well. One of them was Simon Singh who filed an official complaint against the BBC for misleading the public, and eventually won his case.
The notion that acupuncture can serve as an alternative to anaesthesia or other surgical conditions crops up with amazing regularity. It is important not least because is often used as a promotional tool with the implication that, IF ACUPUNCTURE CAN ACHIVE SUCH DRAMATIC EFFECTS, IT MUST BE AN INCREDIBLY USEFUL TREATMENT! It is therefore relevant to ask what the scientific evidence tells us about this issue.
This was the question we wanted to address in a recent publication. Specifically, our aim was to summarise recent systematic reviews of acupuncture for surgical conditions.
Thirteen electronic databases were searched for relevant reviews published since 2000. Data were extracted by two independent reviewers according to predefined criteria. Twelve systematic reviews met our inclusion criteria. They related to the prevention or treatment of post-operative nausea and vomiting as well as to surgical or post-operative pain. The reviews drew conclusions which were far from uniform; specifically for surgical pain the evidence was not convincing. We concluded that “the evidence is insufficient to suggest that acupuncture is an effective intervention in surgical settings.”
So, Kathy Sykes’ comment was misguided in more than just one way: firstly, the scene she described in the film did not support what she was saying; secondly, the scientific evidence fails to support the notion that acupuncture can be used as an alternative to analgesia during surgery.
This story has several positive outcomes all the same. After seeing the BBC programme, Simon Singh contacted me to learn my views on the matter. This prompted me to support his complaint against the BBC and helped him to win this case. Furthermore, it led to a co-operation and friendship which produced our book TRICK OR TREATMENT.
I am sure, we have all heard it hundreds of times: THERE ARE IMPORTANT LINKS BETWEEN OUR DIET AND CERTAIN CANCERS. The evidence for this statement seems fairly compelling. Yet it also is complex and often confusing.
A recent review, for instance, suggested that fruits (particularly citrus) and vegetable consumption may be beneficial in the primary prevention of pancreatic cancer, the consumption of whole grains has been shown to reduce the risk and fortification of whole grains with folate may confer further protection. Red meat, cooked at high temperatures, should be avoided, and replaced with poultry or fish. Total fat should be reduced. The use of curcumin and other flavonoids should be encouraged in the diet. Another equally recent review, however, indicated that there is no conclusive evidence as an independent risk factor for isolated nutrients versus adoption of dietary patterns for cancer risk. Cancer colon risk derived from meat intake is influenced by both total intake and its frequency. The interaction of phenolic compounds on metabolic and signalling pathways seems to exert an inhibitory effect on cell proliferation and tumor metastasis and induces apoptosis in various types of cancer cells, including colon, lung, prostate, hepatocellular or breast cancer. A third recent review concluded that cruciferous vegetable intake protects against cancer of the colon, while a forth review suggested that the Mediterranean dietary pattern and diets composed largely of vegetables, fruit, fish, and soy are associated with a decreased risk of breast cancer. There was no evidence of an association between traditional dietary patterns and risk of breast cancer.
Not least based on these mixed messages from the scientific literature, an entire industry has developed selling uncounted alternative cancer-diets and dietary supplements to desperate patients and consumers. They promise much more than just cancer prevention, in fact, leave little doubt about the notion that cancer might be curable by diet. Here are just a few quotes from the thousands of websites promoting alternative cancer diets:
- The Ketogenic Diet is believed capable of starving cancer cells to death, and thus capable of restricting tumour development.
- a more alkaline body makes it difficult for tumors to grow.
- Budwig diet: This diet was developed by Dr. Johanna Budwig who was nominated for the noble Prize sixth times. The diet is intended as a preventative as well as an alternative cancer treatment.
- the Gerson Therapy naturally reactivates your body’s magnificent ability to heal itself – with no damaging side effects. This a powerful, natural treatment boosts the body’s own immune system to heal cancer, arthritis, heart disease, allergies, and many other degenerative diseases. Dr. Max Gerson developed the Gerson Therapy in the 1930s, initially as a treatment for his own debilitating migraines, and eventually as a treatment for degenerative diseases such as skin tuberculosis, diabetes and, most famously, cancer.
- the concept of macrobiotics is much more than an alternative diet for cancer, or any other illness, but rather the ancient Chinese belief that all life, indeed the whole universe, is a balance of two opposing forces Yin and Yang.
Confused? Yes, I do worry how many cancer patients listen to these claims and pin their hopes on one of these diets. But what exactly does the evidence tell us about them?
A German team of researchers evaluated the following alternative cancer-diets: raw vegetables and fruits, alkaline diet, macrobiotics, Gerson’s regime, Budwig’s and low carbohydrate or ketogenic diet. Their extensive searches of the published literature failed to find clinical evidence supporting any of the diets. Furthermore, case reports and pre-clinical data pointed to the potential harm of some of these diets. The authors concluded that considering the lack of evidence of benefits from cancer diets and potential harm by malnutrition, oncologists should engage more in counselling cancer patients on such diets.
In other words, alternative cancer diets – and I mean not just the ones mentioned above, but all of them – are not supported by good evidence for efficacy as a treatment or prevention of any type of cancer. In addition, they might also cause harm.
What follows is obvious: cancer patients should take sound nutritional advice and adopt a healthy general life-style. But they should run a mile as soon as anyone suggests an alternative dietary cure for their disease.
Even relatively well-informed people tend to think that homeopathy might be quirky and useless but, so what, it cannot do any harm. This is perhaps true for the homeopathic remedies but it does certainly not apply to the homeopaths. As soon as there is a public health problem, homeopaths claim that their approach offers a solution – never mind the evidence to the contrary. Just look at what they presently try to sell us in terms of cold and flu treatments!
The often criminal fight of homeopaths against public health is nowhere clearer than with their never-ending propaganda against the most successful public health measure in the history of medicine, immunisation. Some professional organisations of homeopathy have issued politically correct statements about this and thus feel they are out of the firing line. But, as far as I can see, most homeopaths are against vaccinations. Their arguments are wilfully misguided; here are just a few examples:
- It is well known that measles is an important development milestone in the life and maturing processes in children. Why would anybody want to stop or delay the maturation processes of children and of their immune systems?
- Homoeopathy offers an option for disease prevention and cure. There is scientific evidence in favour of homoeopathy for prevention of diseases.
- Seek out homeopathic, osteopathic, naturopathic, or Chinese medical constitutional treatment to boost your child’s immune system and help them be as healthy as they can be.
- If your children do get sick, use homeopathy to help their immune system get over it. Homeopathy is very effective in epidemics of acute illness. Either see a homeopath, buy a book on homeopathic acute care, or take a class on acute homeopathic prescribing.
- It is possible to prevent post-vaccination damage by giving the homeopathic dilution of the vaccine shortly before and after the vaccination in the C200 dilution.
- there are many recorded cases of people making dramatic recoveries with homeopathic medicines following a bad reaction to a vaccination. Expert advice from a registered homeopath is usually required.
- As you would keep your children away from toxic chemicals in the environment as much as possible, inform yourself about the toxicity of the solutions that are being injected into their bloodstream. It’s up to you to find the information: no one loves your children the way you do.
If you think I cherry-picked these quotes, you are mistaken. I simply used the citations as they appeared on my computer screen after a simple Google search. You might try this yourself because there are hundreds, if not thousands more to be discovered.
A typical and interesting example of a homeopathic anti-vaccinationist is Oksana Frolov, D.Hom. graduate of Saint Petersburg, Russia, I.P.Pavlov State Medical University, General Medicine, and graduate of Los Angeles School of Homeopathy. She states that, although I do hold a medical degree, I am not a licensed medical health provider in the United States. As a homeopathic practitioner, I will provide you with the treatment which is alternative or complementary to healing arts that are licensed by the State of California. On her blog, she provides detailed advice for people who might be uncertain whether to vaccinate their children: immunisation… can cause some very serious side effects including permanent brain damage, epilepsy, autism, and mental retardation. With so many vaccinations being required, doctors often have to administer several shots at a time, which can often result in a disaster. Vaccines, along with the elements that are supposed to create the antibodies, also contain mercury, aluminum, formaldehyde, animal tissue, animal blood, human cell from aborted babies, potatoes, yeast, lactose, phenol, antibiotics and unrelated species of germs that inadvertently get into the vaccines. Do you really want all this to be injected into your child just to prevent him or her from having a chicken pox? Vaccines are said to work by stimulating the body to produce antibodies, which are supposed to protect us from an invasion of harmful germs. Childhood diseases, such as measles, mumps, rubella and chicken pox, affect the immune system in a way that makes most people immune to them for the rest of their lives. Vaccinations, on the other hand, create an artificial immunity that wears off and allows the person to catch the disease later in life….
Homeopathy has proved to be very effective in treatment of childhood diseases, as well as other infections. From its earliest days, homeopathy has been able to treat epidemic disease, such as cholera, typhus, yellow fever, and diphtheria, with a substantial rate of success, when compared to conventional treatments.
Doctors who practice homeopathy usually claim that only non-medically qualified homeopaths hold such deranged views. Dr Frolov shows us that this assumption is clearly not true. In my experience, most homeopaths, medical or not, advise their patients against immunizations or are at least very cagey about this subject in order to raise doubts in concerned parents. Professional organisations of homeopaths usually hide behind some powerless statement in favour of informed choice; yet they must be well-aware that many of their members fail to abide by it. And what do they do about it? Nothing!
Yes, I am afraid the fight of many homeopaths against public health is active, incessant and often criminal. Of course, they do not for one second believe that they are doing anything wrong; on the contrary, they are convinced of their good intentions. As Bert Brecht once wrote, THE OPPOSITE OF GOOD IS NOT EVIL, BUT GOOD INTENTIONS.
Pyruvate, a ketone and an alpha-keto acid, occurs naturally in the body when glucose is converted into energy. It is part of the Krebs cycle, the complex chain of reactions in which nutrients are metabolised to provide energy. High doses of pyruvate seem to stimulate the breakdown of fat in the body. It is therefore not surprising that pyruvate is used in all sorts of slimming aids; and if the advertising for ‘fat burners’ is to be believed, pyruvate is just the ticket for the desperate slimmer.
One such product advertisement, for instance, claims that sodium pyruvate and potassium pyruvate, which can act as a stimulant for the metabolism, adding to the thermogenesis process. Pyruvates have been found in studies to reduced the storage of fat in the body and convert the food source into calories which are then burned off in the production of heat. In one study, rats were injected with three fat burners, including pyruvates, and the rats given the pyruvates burned the greatest amount of fat by increasing the rat’s resting metabolic rate. With the elevated resting metabolic rate, the body burned more fat in individuals, which makes pyruvate an excellent source for weight maintenance.
So, maybe pyruvate works for rats – but does it really help those of us who would like to lose a few kilos? Some studies seem to say so, but others don’t. What do we conclude? There can only be one solution: we need a systematic review of the totality of the available trial evidence – and you probably guessed it: we have just published such an article.
The objective of our systematic review was to examine the efficacy of pyruvate in reducing body weight. Extensive literature searches identifies 9 RCTs of which 6 were met our inclusion criteria. All had methodological weaknesses. The meta-analysis revealed a statistically significant difference of 0.72 kg in body weight with pyruvate compared to placebo. The magnitude of the effect is small, and its clinical relevance is therefore uncertain. Adverse events included gas, bloating, diarrhoea, and increase in low-density lipoprotein cholesterol.
Our conclusion: The evidence from randomized clinical trials does not convincingly show that pyruvate is efficacious in reducing body weight. Limited evidence exists about the safety of pyruvate. Future trials involving the use of this supplement should be more rigorous and better reported.
Pyruvate supplements are popular; people who want to lose weight are misled into believing that they are effective. Bodybuilders as well as other athletes tend to take them because pyruvate is claimed to reduce body fat and enhance the ability to use energy more efficiently. None of these assumptions is based on sound evidence. Regardless of the evidence, a whole industry is exploiting the gullible and doing very well on it.
As these ‘fat burners’ are by no means cheap, I recommend a more efficient and more economical method for normalising body weight: eat a little less and move a bit more – I know it’s naff, but it works!
One of the best-selling supplements in the UK as well as several other countries is evening primrose oil (EPO). It is available via all sorts of outlets (even respectable pharmacies – or is that supposedly respectable?), and is being promoted for a wide range of conditions, including eczema. The NIH website is optimistic about its efficacy: “Evening primrose oil may have modest benefits for eczema.” Our brand-new Cochrane review was aimed at critically assessing the effects of oral EPO or borage oil (BO) on the symptoms of atopic eczema, and it casts considerable doubt on this somewhat uncritical view.
Here is what we did: We searched six databases as well as online trials registers and checked the bibliographies of included studies for further references to relevant trials. We corresponded with trial investigators and pharmaceutical companies to identify unpublished and ongoing trials. We also performed a separate search for adverse effects. All RCTs investigating oral intake of EPO or BO for eczema were included.
Two experts independently applied eligibility criteria, assessed risk of bias, and extracted data. We pooled dichotomous outcomes using risk ratios (RR), and continuous outcomes using the mean difference (MD). Where possible, we pooled study results using random-effects meta-analysis and tested statistical heterogeneity.
And here is what we found: 27 studies with a total of 1596 participants met our inclusion criteria: 19 studies tested EPO, and 8 studies assessed BO. A meta-analysis of results from 7 studies showed that EPO failed to improve global eczema symptoms as reported by participants and doctors. Treatment with BO also failed to improve global eczema symptoms. 67% of the studies had a low risk of bias for random sequence generation; 44%, for allocation concealment; 59%, for blinding; and 37%, for other biases.
Our conclusions were clear: Oral borage oil and evening primrose oil lack effect on eczema; improvement was similar to respective placebos used in trials. Oral BO and EPO are not effective treatments for eczema.
The very wide-spread notion that EPO is effective for eczema and a range of other conditions was originally promoted by the researcher turned entrepreneur, D F Horrobin, who claimed that several human diseases, including eczema, were due to a lack of fatty acid precursors and could thus be effectively treated with EPO. In the 1980s, Horrobin began to sell EPO supplements without having conclusively demonstrated their safety and efficacy; this led to confiscations and felony indictments in the US. As chief executive of Scotia Pharmaceuticals, Horrobin obtained licences for several EPO-preparations which later were withdrawn for lack of efficacy. Charges of mismanagement and fraud led to Horrobin being ousted as CEO by the board of the company. Later, Horrobin published a positive meta-analysis of EPO for eczema where he excluded the negative results of the largest published trial, but included results of 7 of his own unpublished studies. When scientists asked to examine the data, Horrobin’s legal team convinced the journal to refuse the request.
The evidence for EPO is negative not just for eczema. To the best of my knowledge, there is not a single disease or symptom for which it demonstrably works. Our own review of the data concluded ” EPO has not been established as an effective treatment for any condition”
Our new Cochrane review might help to put this long saga to rest. In my view, it is a fascinating tale of a scientist being blinded by creed and ambition. The results of such errors can be dramatic. Horrobin misled all of us: patients, health care professionals, scientists, regulators, decision makers, businessmen. This caused unnecessary expense and set back research efforts in a multitude of areas. I find the tale also fascinating from other perspectives; for instance, it begs the question why so many ‘respectable’ manufacturers and retailers are still allowed to make money on EPO. Is it not time to debunk the EPO-myth and say it as clearly as possible: EPO helps only those who financially profit from misleading the public?
Some time ago, we published a systematic review aimed at identifying what patients might hope for when they consult a practitioner of alternative medicine. The most common expectations that emerged from this research are listed here:
- Less side-effects
- Symptom relief
- Cure of their disease
- Cope better with their condition
- Improve quality of life
- Boost immune system
- Prevention of illness
- Good therapeutic relationship with a clinician
- Holistic care
- Emotional support
- Control over their own health
In several ways, I think, these expectations are revealing; here I want to focus on one particular aspect, and ask the following question: To what extent are patients driven to see alternative practitioners simply because conventional medicine is letting them down? It seems to me that several items in the list above are an implicit criticism of mainstream medicine. This might get much clearer, if I re-phrase the points a bit: according to our findings, patients feel:
- that conventional treatments have too many side-effects;
- that they frequently fail to ease their symptoms;
- that they often do not cure the disease;
- that doctors do not enable their patients to cope with their condition;
- that doctors care not enough about their patients’ quality of life;
- that many conventional treatments neglect the importance of the immune system;
- that prevention is not given the importance it should have;
- that doctors are often no good at establishing good therapeutic relationships with their patients;
- that doctors fail to realise that their patients are not just “cases” but whole human individuals;
- that doctors are not providing enough emotional support;
- that doctors fail to empower their patients to be in control of their health.
Some of these points will probably strike a cord with most of us. I for one know of many instances where conventional physicians have failed their patients most miserably. All too often, the failings of modern medicine are as obvious as they are inexcusable! I can fully understand that disappointed patients look for help and compassion elsewhere, and I am quite sure that the failings of modern medicine are an important motivator for people to try alternative medicine.
But looking elsewhere might not be the best approach for improving health care. Alternative practitioners may well be more compassionate than conventional clinicians but features like empathy, time and attention can never make good medicine, if they are not accompanied by effective therapies.
The conclusion is therefore simple: whenever we encounter one of the many failings of conventional medicine, instead of turning away in disgust, we ought to make sure that mistakes are corrected, lessons are learnt and improvements are found and put into practice. Our aim must be to generate progress, and it cannot be reached by opting for unproven or dis-proven treatments.
“Don’t take this therapy lightly. Multiple sclerosis, colitis, lupus, rheumatoid arthritis, cancer, hepatitis, hyperactivity, pancreatic insufficiency, psoriasis, eczema, diabetes, herpes, mononucleosis, adrenal failure, allergies and so many other ailments have been relieved through use of this therapy. After you overcome your initial gag response (I know I had one), you will realize that something big is going on, and if you are searching for health, this is an area to investigate. There are numerous reports and double blind studies which go back to the turn of the century supporting the efficacy of using urine for health”. This quote refers to a treatment that I, and probably most readers of this blog, find truly amazing – even in the realm of alternative medicine, we do not often come across a therapy as bizarre as this one: urine therapy.
Urine therapy enthusiasts claim that your own urine administered either externally, internally or both, has a long history of use, that most medical cultures have usefully employed it, that many VIPs swear by it, that it can cure almost all diseases and that it can save lives. What was new to me is the claim that it is supported by numerous double-blind studies.
Such trials would, of course, be entirely feasible; all you need to do is to give one group of patients the experimental treatment, while the other takes a placebo. Recruitment might be a bit of a problem, and the ethics committee might raise one or two eyebrows but, in theory, it certainly seems doable. So where are the “numerous” studies?
A quick, rough and ready Medline-Search found several unfortunate authors with the last name of “URINE”, yet no clinical trials of urine therapy emerged. A little more time-consuming search through my books on alternative medicine revealed nothing that remotely resembled evidence. At this point, I arrived at the conclusion that the clinical trials are either non-existent or extremely well hidden. Further searches of the proponents’ literature, websites etc made me settle for the former explanation.
All this could be entirely irrelevant, perhaps slightly amusing, would it not reveal a pattern which is so painfully common in alternative medicine: anyone can claim anything without fear of any type of retribution, gullible consumers are attracted through the exotic flair, VIP-promotion, long history of use etc. and follow in droves [yes, amazingly, urine therapy seems to have plenty of followers]; consequently, lives are put at risk whenever someone starts truly believing the bogus, irresponsible claims that are being made.
I do apologise for the rudeness of my words but I really do think THEY ARE TAKING THE PISS!
