‘Red ginseng’ is an herbal medicine prepared by steaming raw ginseng. This process is believed to increase its pharmacological activity. Further conversion through fermentation is thought to increase its intestinal absorption and bioactivity to diminish its toxicity.

Red ginseng (RG) is traditionally used for diabetes. Our own systematic review of 4 RCTs concluded that the evidence for the effectiveness of RG in controlling glucose in type 2 diabetes is not convincing. Few included studies with various treatment regimens prohibit definitive conclusions. More rigorous studies are needed to clarify the effects of RG on this condition.

Now a new RCT has become available. This study was conducted to investigate the effects of daily supplementation with fermented red ginseng (FRG) on blood sugar levels in subjects with impaired fasting glucose or type 2 diabetes. It was a four-week long, randomized, double-blind, placebo-controlled trial. Forty-two subjects with impaired fasting glucose or type 2 diabetes were randomly allocated to two groups assigned to consume either placebo or FRG three times per day for 4 weeks. Fasting and postprandial glucose profiles during meal tolerance tests were assessed before and after the intervention.

Compared to the placebo, FRG supplementation led to a significant reduction in postprandial glucose levels and to an increase in postprandial insulin levels. There also was a significant improvement in the area under the curve (AUC) in the FRG group. However, fasting glucose, insulin, and lipid profiles did not differ from the placebo group.

The authors of this trial concluded that daily supplementation with FRG lowered postprandial glucose levels in subjects with impaired fasting glucose or type 2 diabetes.

What should we make of these findings? Do they indicate that FRG might be an alternative to conventional anti-diabetic drugs? I would caution that we have tons of data for the latter, while we know far too little about FRG to recommend it for routine use.

On the contrary, the findings could suggest that diabetic patients who are well-controlled with diet or anti-diabetic medication should be avoiding ginseng products. If they actually work, they might significantly interfere with their metabolic control which, in turn, could even endanger their lives.

What is the best treatment for the millions of people who suffer from chronic low back pain (CLBP)? If we are honest, no therapy has yet been proven to be overwhelmingly effective. Whenever something like that happens in medicine, we have a proliferation of interventions which all are promoted as effective but which, in fact, work just marginally. And sure enough, in the case of CLBP, we have a constantly growing list of treatments none of which is really convincing.

One of the latest additions to this list is PILATES.

Pilates? What is this ? One practitioner describes it as follows: In Pilates, we pay a lot of attention to how our body parts are lined up in relation to each other, which is our alignment. We usually think of our alignment as our posture, but good posture is a dynamic process, dependent on the body’s ability to align its parts to respond to varying demands effectively. When alignment is off, uneven stresses on the skeleton, especially the spine, are the result. Pilates exercises, done with attention to alignment, create uniform muscle use and development, allowing movement to flow through the body in a natural way.

For example, one of the most common postural imbalances that people have is the tendency to either tuck or tilt the pelvis. Both positions create weaknesses on one side of the body and overly tight areas on the other. They deny the spine the support of its natural curves and create a domino effect of aches and pains all the way up the spine and into the neck. Doing Pilates increases the awareness of the proper placement of the spine and pelvis, and creates the inner strength to support the natural curves of the spine. This is called having a neutral spine and it has been the key to better backs for many people.

Mumbo-jumbo? Perhaps; in any case, we need evidence! Is there any at all? Surprisingly, the answer is yes. Recently, someone even published a proper systematic review.

This systematic review was aimed at evaluating the effectiveness of Pilates exercise in people with chronic low back pain (CLBP).

A search for RCTs was undertaken in 10 electronic. Two independent reviewers did the selection of evidence and evaluated the quality of the primary studies. To be included, relevant RCTs needed to be published in the English language. From 152 studies, 14 RCTs could be included.

The methodological quality of RCTs ranged from “poor” to “excellent”. A meta-analysis of RCTs was not undertaken due to the heterogeneity of RCTs. Pilates exercise provided statistically significant improvements in pain and functional ability compared to usual care and physical activity between 4 and 15 weeks, but not at 24 weeks. There were no consistent statistically significant differences in improvements in pain and functional ability with Pilates exercise, massage therapy, or other forms of exercise at any time period.

The authors drew the following conclusions: Pilates exercise offers greater improvements in pain and functional ability compared to usual care and physical activity in the short term. Pilates exercise offers equivalent improvements to massage therapy and other forms of exercise. Future research should explore optimal Pilates exercise designs, and whether some people with CLBP may benefit from Pilates exercise more than others.

So, Pilates can be added to the long list of treatments that work for CLBP, albeit not convincingly better than most other therapies on offer. Does that mean these options are all as good or as bad as the next? I don’t think so.

Let’s assume chiropractic/osteopathic manipulations, massage and various forms of exercise are all equally effective. How do we decide which is more commendable than the next? We clearly need to take other important factors into account:

  • cost
  • risks
  • acceptability for patients
  • availability

If we use these criteria, it becomes instantly clear that chiropractic and osteopathy are not favourites in this race for the most commendable CLBP-treatment. They are neither cheap nor free of risks. Massage is virtually risk-free but not cheap. This leaves us with various forms of exercise, including Pilates. But which exercise is better than the next? At present, we do not know, and therefore the last two factors are crucial: if people love doing Pilates and if they easily stick with it, then Pilates is fine.

I am sure chiropractors will (yet again) disagree with me but, to me, this logic could hardly be more straight forward.

My 2008 evaluation of chiropractic concluded that the concepts of chiropractic are not based on solid science and its therapeutic value has not been demonstrated beyond reasonable doubt. It also pointed out that the advice of chiropractors often is dangerous and not in the best interest of the patient: many chiropractors have a very disturbed attitude towards immunisation: anti-vaccination attitudes till abound within the chiropractic profession. Despite a growing body of evidence about the safety and efficacy of vaccination, many chiropractors do not believe in vaccination, will not recommend it to their patients, and place emphasis on risk rather than benefit.

In case you wonder where this odd behaviour comes from, you best look into the history of chiropractic. D. D. Palmer, the magnetic healer who ‘invented’ chiropractic about 120 years ago, left no doubt about his profound disgust for immunisation: “It is the very height of absurdity to strive to ‘protect’ any person from smallpox and other malady by inoculating them with a filthy animal poison… No one will ever pollute the blood of any member of my family unless he cares to walk over my dead body… ” (D. D. Palmer, 1910)

D. D. Palmer’s son, B. J. Palmer (after literally walking [actually it was driving] over his father’s body)  provided a much more detailed explanation for chiropractors’ rejection of immunisation: “Chiropractors have found in every disease that is supposed to be contagious, a cause in the spine. In the spinal column we will find a subluxation that corresponds to every type of disease… If we had one hundred cases of small-pox, I can prove to you, in one, you will find a subluxation and you will find the same condition in the other ninety-nine. I adjust one and return his function to normal… There is no contagious disease… There is no infection…The idea of poisoning healthy people with vaccine virus… is irrational. People make a great ado if exposed to a contagious disease, but they submit to being inoculated with rotten pus, which if it takes, is warranted to give them a disease” (B. J. Palmer, 1909)

Such sentiments and opinions are still prevalent in the chiropractic profession – but today they are expressed in a far less abrupt, more politically correct language: The International Chiropractors Association recognizes that the use of vaccines is not without risk. The ICA supports each individual’s right to select his or her own health care and to be made aware of the possible adverse effects of vaccines upon a human body. In accordance with such principles and based upon the individual’s right to freedom of choice, the ICA is opposed to compulsory programs which infringe upon such rights. The International Chiropractors Association is supportive of a conscience clause or waiver in compulsory vaccination laws, providing an elective course of action for all regarding immunization, thereby allowing patients freedom of choice in matters affecting their bodies and health.

Not all chiropractors share such opinions. The chiropractic profession is currently divided over the issue of immunisation. Some chiropractors now realise that immunisations have been one of the most successful interventions ever for public health. Many others, however, do still vehemently adhere to the gospel of the Palmers.  Statements like the following abound:

Vaccines. What are we taught? That vaccines came on the scene just in time to save civilization from the ravages of infectious diseases. That vaccines are scientifically formulated to confer immunity to certain diseases; that they are safe and effective. That if we stop vaccinating, epidemics will return…And then one day you’ll be shocked to discover that … your “medical” point of view is unscientific, according to many of the world’s top researchers and scientists. That many state and national legislatures all over the world are now passing laws to exclude compulsory vaccines….

Our original blood was good enough. What a thing to say about one of the most sublime substances in the universe. Our original professional philosophy was also good enough. What a thing to say about the most evolved healing concept since we crawled out of the ocean. Perhaps we can arrive at a position of profound gratitude if we could finally appreciate the identity, the oneness, the nobility of an uncontaminated unrestricted nervous system and an inviolate bloodstream. In such a place, is not the chiropractic position on vaccines self-evident, crystal clear, and as plain as the sun in the sky?

Yes, I do agree: the position of far too many chiropractors is ‘crystal clear’ – unfortunately it is also dangerously wrong.

On this blog, I have repeatedly stressed that there is reasonably good evidence to show that some herbal medicines are effective. The one that is probably supported with better evidence than any other is St. John’s wort (SJW). The first systematic review of SJW was published in 1995 and concluded that SJW is an effective symptomatic treatment for various forms of depressions. Meanwhile, many more trials have become available, and the current Cochrane review concludes that the available evidence suggests that the hypericum extracts tested in the included trials a) are superior to placebo in patients with major depression; b) are similarly effective as standard antidepressants; c) and have fewer side effects than standard antidepressants. 

This must be good news for many patients; particularly the fact that SJW is much safer than synthetic antidepressants seems attractive. But don’t be fooled – SJW may still cause harm. If taken on its own, it is almost as safe as placebo, but when it is combined with other drugs, it can powerfully interact and significantly lower the plasma level of a wide range of prescription medicines.

Some proponents of alternative medicine have suggested that this caution is alar@BocktheRobber mist, and they insist that, actually, the danger is minimal. Are they correct? We need data, I think, not opinion.

A new article provides new insights.

The objective of this study was to assess how often SJW is prescribed with medications that may interact dangerously with it. The researchers conducted a retrospective analysis of nationally representative data from the National Ambulatory Medical Care Survey. The study setting was U.S. non-federal outpatient physician offices. Patients who were prescribed SJW between 1993 and 2010 were the subjects. The outcome measures were medications co-prescribed with SJW.

Twenty-eight percent of SJW visits involved a drug that has potentially dangerous interaction with SJW. These included selective serotonin reuptake inhibitors, benzodiazepines, warfarin, statins, verapamil, digoxin, and oral contraceptives.

The authors concluded that SJW is frequently used in potentially dangerous combinations. Physicians should be aware of these common interactions and warn patients appropriately.

There is little to add – perhaps just this: the awareness of physicians is undoubtedly desirable, but it is not enough; as SJW and other herbal medicines are usually self-prescribed, consumers’ awareness of the risks associated with herbal medicines is at least as important, I think.

Guest post by Michelle Dunbar

According to the CDC, more than 30,000 people died as a result of a drug overdose in 2010. Of those deaths none were attributed to marijuana. Instead the vast majority were linked to drugs that are legally prescribed such as opiates, anti-depressants, anti-psychotics, tranquilizers and benzodiazepines. As misuse and abuse of prescription medications continues to rise, the marijuana legalization debate is also heating up.

Nearly 100 years of propaganda, fear mongering and blatant misinformation regarding marijuana has taken its toll on our society. As the veil of lies surrounding marijuana is being lifted, more and more people are pushing for legalization. Marijuana is now legal for both medicinal and recreational use in two states and other states are introducing legislation of their own. Marijuana is approved for medicinal use with a prescription in 21 states and also Washington, D.C. with most other states expected to introduce legislation to approve use for medicinal purposes in the next few years.

Last year Dr. Sanjay Gupta, the medical correspondent for CNN, aired a controversial documentary, “Weed”, where he showed various promising medicinal uses for marijuana. He admits that he was wrong for many years about marijuana legalization, and after doing his own extensive research he is encouraged by the many real life cases he has seen where people with chronic, serious medical issues have been and continue to be helped by marijuana. He noted that marijuana does not have the dangerous side effects that many prescription medications do and that it is actually safer than many drugs being prescribed today. Dr. Gupta said in the program that there is not one documented case where death was due to marijuana overdose and he is right.

But as with any systematic paradigm shift, there will always be those whose minds are closed to change. So as the march toward legalization continues, there is new anti-legalization propaganda being written and spread through mainstream and social media. There have been multiple reports out of Colorado that there are now deaths attributed to marijuana overdose. Some say children were involved which automatically evokes feelings of fear in parents across the country. But when I tried to find more reliable sources to verify these articles, none existed. The AP reported on April 2 that a Wyoming college student jumped to his death in Colorado after eating a marijuana cookie while on Spring Break in Colorado. The autopsy listed marijuana intoxication as a “significant contributing factor” in the teen’s death. (Gurman)

Like alcohol, Colorado bans the sale of marijuana and marijuana edibles to people under the age of 21. But much like alcohol, teens that want to get it will always find a way. This young man was just 19, and his death has been ruled accidental. While it is true his death is tragic, is it a reason to reverse the course with marijuana? If you believe this is the case then you must consider the real dangers posed by alcohol. Many people who would like to see marijuana legalized say that it is much safer than the legal drug alcohol. Based solely on the numbers of hospitalizations and deaths, especially with young people, they would be right.

According to an article posted on Forbes.com in March of this year, “1,825 college students between the ages of 18 and 24 die each school year from alcohol-related unintentional injuries.” The author, Dr. Robert Glatter, MD attributes these deaths to one of the leading health risks facing our young people, and that is binge drinking. This number is quite small in comparison to emergency room visits and hospitalizations of young people that are a direct result of alcohol use.

Taking the most heat are the marijuana edibles that are now for sale in states where marijuana has become legal. The concern is that children are eating marijuana laced candy and baked goods and becoming ill. This would seem to be confirmed by an article in USA Today that reported that calls to the Rocky Mountain Poison Control is Colorado regarding marijuana ingestion in children had risen to 70 cases last year. While they admitted that this number was low, it was the rapid rise from years previous that caused concern. To put this in perspective, there are approximately 1.4 million pediatric poisonings each year involving prescription medications not including marijuana. (Henry, et.al) That is an average of approximately 28,000 calls per state. Tragically several hundreds of these cases result in deaths of these children, with the highest rates of death involving narcotics, sedatives and anti-depressants. (Henry, et.al.)

Of those 70 cases reported in Colorado involving marijuana, none resulted in death. The results are quite clear marijuana is as safe as prescription drugs are dangerous. For those who want to weigh in on the marijuana legalization debate, it is important to do your research, look at the big picture and put everything in perspective. Alcohol is legal and heavily regulated, yet its use is linked to thousands of deaths each year. Prescription drugs are legal and heavily regulated, yet they too are linked to thousands of deaths each year. Marijuana, on the other hand, is not legal and not available in much of the country, and thus far has not caused one death from overdose ever.

Additionally, research is showing marijuana has promise in treating many diseases more effectively and safely than dangerous prescription medications being used today. From cancer to epilepsy to depression and anxiety, to chronic autoimmune diseases, scientists are just scratching the surface when it comes to the potential life-changing and perhaps even, life-saving uses for marijuana.

The safety of the manual treatments such as spinal manipulation is a frequent subject on this blog. Few experts would disagree with the argument that more good data are needed – and what could be better data than that coming from a randomised clinical trial (RCT)?

The aim of this RCT was to investigate differences in occurrence of adverse events between three different combinations of manual treatment techniques used by manual therapists (i.e. chiropractors, naprapaths, osteopaths, physicians and physiotherapists) for patients seeking care for back and/or neck pain.

Participants were recruited among patients seeking care at the educational clinic of the Scandinavian College of Naprapathic Manual Medicine in Stockholm. 767 patients were randomized to one of three treatment arms:

  1.  manual therapy (i.e. spinal manipulation, spinal mobilization, stretching and massage) (n = 249),
  2.  manual therapy excluding spinal manipulation (n = 258)
  3.  manual therapy excluding stretching (n = 260).

Treatments were provided by students in the seventh semester (of total 8). Adverse events were monitored via a questionnaire after each return visit and categorized in to five levels:

  1. short minor,
  2. long minor,
  3. short moderate,
  4. long moderate,
  5. serious

This was based on the duration and/or severity of the event.

The most common adverse events were soreness in muscles, increased pain and stiffness. No differences were found between the treatment arms concerning the occurrence of these adverse event. Fifty-one percent of patients, who received at least three treatments, experienced at least one adverse event after one or more visits. Women more often had short moderate adverse events, and long moderate adverse events than men.

The authors conclude that adverse events after manual therapy are common and transient. Excluding spinal manipulation or stretching do not affect the occurrence of adverse events. The most common adverse event is soreness in the muscles. Women reports more adverse events than men.

What on earth is naprapathy? I hear you ask. Here is a full explanation from a naprapathy website:

Naprapathy is a form of bodywork that is focused on the manual manipulation of the spine and connective tissue. Based on the fundamental principles of osteopathy and chiropractic techniques, naprapathy is a holistic and integrative approach to restoring whole health. In fact, naprapathy often incorporates multiple, complimentary therapies, such as massage, nutritional counseling, electrical muscle stimulation and low-level laser therapy.

Naprapathy also targets vertebral subluxations, or physical abnormalities present that suggest a misalignment or injury of the spinal vertebrae. This analysis is made by a physical inspection of the musculoskeletal system, as well as visual observation. The practitioner will also conduct a lengthy interview with the client to help determine stress level and nutritional status as well. An imbalance along one or more of these lines may signal trouble within the musculoskeletal structure.

The naprapathy practitioner is particularly skilled in identifying restricted or stressed components of the fascial system, or connective tissue. It is believed that where constriction of muscles, ligaments, and tendons exists, there is impaired blood flow and nerve functioning. Naprapathy attempts to correct these blockages through hands-on manipulation and stretching of connective tissue. However, since this discipline embodies a holistic approach, the naprapathy practitioner is also concerned with their client’s emotional health. To that end, many practitioners are also trained in psychotherapy and even hypnotherapy.

So, now we know!

We also know that the manual therapies tested here cause adverse effects in about half of all patients. This figure ties in nicely with the ones we had regarding chiropractic: ~ 50% of all patients suffer mild to moderate adverse effects after chiropractic spinal manipulation which usually last 2-3 days and can be strong enough to affect their quality of life. In addition very serious complications have been noted which luckily seem to be much rarer events.

In my view, this raises the question: DO THESE TREATMENTS GENERATE MORE GOOD THAN HARM? I fail to see any good evidence to suggest that they do – but, of course, I would be more than happy to revise this verdict, provided someone shows me the evidence.

The aim of this survey was to investigate the use of alternative medicines (AMs) by Scottish healthcare professionals involved in the care of pregnant women, and to identify predictors of usage.

135 professionals (midwives, obstetricians, anaesthetists) involved in the care of pregnant women filled a questionnaire. A response rate of 87% was achieved. A third of respondents (32.5%) had recommended (prescribed, referred, or advised) the use of AMs to pregnant women. The most frequently recommended AMs modalities were: vitamins and minerals (excluding folic acid) (55%); massage (53%); homeopathy (50%); acupuncture (32%); yoga (32%); reflexology (26%); aromatherapy (24%); and herbal medicine (21%). Univariate analysis identified that those who recommended AMs were significantly more likely to be midwives who had been in post for more than 5 years, had received training in AMs, were interested in AMs, and were themselves users of AMs. However, the only variable retained in bivariate logistic regression was ‘personal use of AM’ (odds ratio of 8.2).

The authors draw the following conclusion: Despite the lack of safety or efficacy data, a wide variety of AM therapies are recommended to pregnant women by approximately a third of healthcare professionals, with those recommending the use of AMs being eight times more likely to be personal AM users.

There are virtually thousands of websites which recommend unproven treatments to pregnant women. This one may stand for the rest:

Chamomile, lemon balm, peppermint, and raspberry leaf are also effective in treating morning sickness. Other helpful herbs for pregnancy discomforts include:

  • dandelion leaf for water retention
  • lavender, mint, and slippery elm for heartburn
  • butcher’s broom, hawthorn, and yarrow, applied externally to varicose veins
  • garlic for high blood pressure
  • witch hazel, applied externally to haemorrhoids.

Our research has shown that midwives are particularly keen to recommend and often sell AMs to their patients. In fact, it would be difficult to find a midwife in the UK or elsewhere who is not involved in this sort of thing. Similarly, we have demonstrated that the advice given by herbalists is frequently not based on evidence and prone to harm the unborn child, the mother or both. Finally, we have pointed out that many of the AMs in question are by no means free of risks.

The most serious risk, I think, is that advice to use AM for health problems during pregnancy might delay adequate care for potentially serious conditions. For instance, the site quoted above advocates garlic for a pregnant women who develops high blood pressure during pregnancy and dandelion for water retention. These two abnormalities happen to be early signs that a pregnant women might be starting to develop eclampsia. Treating such serious conditions with a few unproven herbal remedies is dangerous and recommendations to do so are irresponsible.

I think the new survey discussed above suggests a worrying degree of sympathy amongst conventional healthcare professionals for unproven treatments. This is likely to render healthcare less effective and less safe and is not in the interest of patients.

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.

Web-sites have become a leading source of information on health matters. This is particularly true in the realm of alternative medicine. Conventional health care professionals often know too little about this subject to advise their patients, and alternative practitioners are usually too biased to be trusted. So many consumers turn to the Internet and hope that it offers information which is reliable. But is it?

American pharmacists published a study evaluating the quality of on-line information on herbal supplements. They conducted a search of 13 common herbals – including black cohosh, echinacea, garlic, ginkgo, ginseng, green tea, kava, saw palmetto, and St John’s wort - and reviewed the top 50 Web sites for each using a Google search. Subsequently, they analysed clinical claims, warnings, and other safety information.

A total of 1179 Web sites were examined in this way. Less than 8% of retail sites provided information regarding potential adverse effects, drug interactions, and other safety information; only 10.5% recommended consultation with a healthcare professional. Less than 3% cited scientific literature to support their claims.

The authors’ conclusions were worrying: Key safety information is still lacking from many online sources of herbal information. Certain nonretail site types may be more reliable, but physicians and other healthcare professionals should be aware of the variable quality of these sites to help patients make more informed decisions.

Having conducted my fair share of similar research (e.g. here or here or here or here), I can only concur with these conclusions. When it comes to health care, the Internet is a scary place! In the realm of alternative medicine, it is dominated by people who seem not to care much about anything other than their profits.

But what can be done to change this situation? How can we protect the public from Internet-charlatans? How can one control the Internet? I wish I knew! But there are nevertheless means of directing consumers to those sites which do offer reliable information. Kite-marking high quality sites might be one way of achieving this. This task would, of course, be huge and difficult, but in the interest of public safety, governments and other official institutions should consider tackling it.

Herbal medicine is popular. Consumers seem to be attracted by the notion that they are natural – and if it’s natural, it must be safe!!! But do we really know what is in the product that we might be buying? A recently published analytical study aimed to investigate herbal product integrity and authenticity with the goal of protecting consumers from health risks associated with product substitution and contamination.

The researchers used DNA barcoding to conduct a blind test of the authenticity for (i) 44 herbal   products representing 12 companies and 30 different species of herbs, and (ii) 50 leaf samples collected from 42 herbal species. They also assembled the first   standard reference material (SRM) herbal barcode library from 100 herbal species of   known provenance that were used to identify the unknown herbal products and leaf samples.

DNA barcodes from 91% of the herbal products and all leaf samples could be recovered. 59% of the products tested contained DNA barcodes from plant species not listed on the labels. 48% of the products could be authenticated but one-third of these also contained contaminants and or fillers not listed on the label. Product substitution occurred in 30 of the 44 products tested and only 2 of the 12 companies sold products without any substitution, contamination or fillers. Some of the contaminants we found pose serious health risks to consumers.

Based on these findings, the authors drew the following conclusions: Most of the herbal products tested were of poor quality, including considerable product substitution, contamination and use of fillers. These activities dilute the effectiveness of otherwise useful remedies, lowering the perceived value of all related products because of a lack of consumer confidence in them. We suggest that the herbal industry should embrace DNA barcoding for authenticating herbal products through testing of raw materials used in manufacturing products. The use of an SRM DNA herbal barcode library for testing bulk materials could provide a method for ‘best practices’ in the manufacturing of herbal products. This would provide consumers with safe, high quality herbal products.

These findings are fairly alarming. I have previously blogged about the fact that herbal products are far to often adulterated or contaminated. Now it seems that we have to add to this list of dangers the substitution of the herbal ingredient with a presumably less expensive but potentially toxic herb that should not legally be there at all.
