This press-release caught my eye today. It relates to an article that does not seem to be available yet (at least when I looked it was not on Medline). As it is highly relevant to issues that we have repeatedly discussed on this blog, let me quote the important sections of the press-release instead:
To investigate alternative medicine use and its impact on survival compared to conventional cancer treatment, the researchers studied 840 patients with breast, prostate, lung, and colorectal cancer in the National Cancer Database (NCDB) — a joint project of the Commission on Cancer of the American College of Surgeons and the American Cancer Society. The NCDB represents approximately 70% of newly diagnosed cancers nationwide. Researchers compared 280 patients who chose alternative medicine to 560 patients who had received conventional cancer treatment.
The researchers studied patients diagnosed from 2004 to 2013. By collecting the outcomes of patients who received alternative medicine instead of chemotherapy, surgery, and/or radiation, they found a greater risk of death. This finding persisted for patients with breast, lung, and colorectal cancer. The researchers concluded that patients who chose treatment with alternative medicine were more likely to die and urged for greater scrutiny of the use of alternative medicine for the initial treatment of cancer.
“We now have evidence to suggest that using alternative medicine in place of proven cancer therapies results in worse survival,” said lead author Dr. Skyler Johnson. “It is our hope that this information can be used by patients and physicians when discussing the impact of cancer treatment decisions on survival.”
Dr. Cary Gross, co-author of the study, called for further research, adding, “It’s important to note that when it comes to alternative cancer therapies, there is just so little known — patients are making decisions in the dark. We need to understand more about which treatments are effective — whether we’re talking about a new type of immunotherapy or a high-dose vitamin — and which ones aren’t, so that patients can make informed decisions.”

Regular readers of my blog will not be surprised; we have discussed similar findings before:
Korean researchers evaluated whether complementary/alternative medicine (CAM) -use influenced the survival and health-related quality of life (HRQOL) of terminal cancer patients. From July 2005 to October 2006, they prospectively studied a cohort study of 481 cancer patients. During a follow-up of 163.8 person-years, they identified 466 deceased patients. Their multivariate analyses of these data showed that, compared with non-users, CAM-users did not have better survival. Using mind-body interventions or prayer was even associated with significantly worse survival. CAM users reported significantly worse cognitive functioning and more fatigue than nonusers. In sub-group analyses, users of alternative medical treatments, prayer, vitamin supplements, mushrooms, or rice and cereal reported significantly worse HRQOL. The authors conclude that “CAM did not provide any definite survival benefit, CAM users reported clinically significant worse HRQOLs.”
A Norwegian study examined the association between CAM-use and cancer survival. Survival data were obtained with a follow-up of 8 years for 515 cancer patients. A total of 112 patients used CAM. During the follow-up period, 350 patients died. Death rates were higher in CAM-users (79%) than in those who did not use CAM (65%). The hazard ratio of death for CAM-use compared with no use was 1.30. The authors of this paper concluded that “use of CAM seems to predict a shorter survival from cancer.”
This study from the US was aimed at determining whether CAM use impacts on the prognosis of breast cancer patients. Health Eating, Activity, and Lifestyle (HEAL) Study participants (n = 707) were diagnosed with stage I-IIIA breast cancer. Participants completed a 30-month post-diagnosis interview including questions on CAM use (natural products such as dietary and botanical supplements, alternative health practices, and alternative medical systems), weight, physical activity, and comorbidities. Outcomes were breast cancer-specific and total mortality, which were ascertained from the Surveillance Epidemiology and End Results registries in Western Washington, Los Angeles County, and New Mexico. Cox proportional hazards regression models were fit to data to estimate hazard ratios (HR) and 95 % confidence intervals (CI) for mortality. Models were adjusted for potential confounding by socio-demographic, health, and cancer-related factors. Among the 707 participants, 70 breast cancer-specific deaths and 149 total deaths were reported. 60.2 % of participants reported CAM use post-diagnosis. The most common CAM were natural products (51 %) including plant-based estrogenic supplements (42 %). Manipulative and body-based practices and alternative medical systems were used by 27 and 13 % of participants, respectively. No associations were observed between CAM use and breast cancer-specific (HR 1.04, 95 % CI 0.61-1.76) or total mortality (HR 0.91, 95 % CI 0.63-1.29). The authors concluded that CAM use was not associated with breast cancer-specific mortality or total mortality. Randomized controlled trials may be needed to definitively test whether there is harm or benefit from the types of CAM assessed in HEAL in relation to mortality outcomes in breast cancer survivors.
Some forms of CAM might be effective in supportive or palliative care of cancer patients. However, if it is used or recommended as a cancer therapy, our alarm bells should start ringing.
I just found the new article; here is its abstract:
There is limited available information on patterns of utilization and efficacy of alternative medicine (AM) for patients with cancer. We identified 281 patients with nonmetastatic breast, prostate, lung, or colorectal cancer who chose AM, administered as sole anticancer treatment among patients who did not receive conventional cancer treatment (CCT), defined as chemotherapy, radiotherapy, surgery, and/or hormone therapy. Independent covariates on multivariable logistic regression associated with increased likelihood of AM use included breast or lung cancer, higher socioeconomic status, Intermountain West or Pacific location, stage II or III disease, and low comorbidity score. Following 2:1 matching (CCT = 560 patients and AM = 280 patients) on Cox proportional hazards regression, AM use was independently associated with greater risk of death compared with CCT overall (hazard ratio [HR] = 2.50, 95% confidence interval [CI] = 1.88 to 3.27) and in subgroups with breast (HR = 5.68, 95% CI = 3.22 to 10.04), lung (HR = 2.17, 95% CI = 1.42 to 3.32), and colorectal cancer (HR = 4.57, 95% CI = 1.66 to 12.61). Although rare, AM utilization for curable cancer without any CCT is associated with greater risk of death.
The Gerson therapy, CANCER RESEARCH UK correctly informs us, is an alternative therapy which means it is usually used instead of conventional cancer treatment. It aims to rid the body of toxins and strengthen the body’s immune system. There is no scientific evidence that Gerson therapy can treat cancer. In fact, in certain situations Gerson therapy can be very harmful to your health. The diet should not be used instead of conventional cancer treatment.
I would go two steps further:
- I would avoid the treatment at all cost.
- I would distrust anyone who promotes it.
Like this article about Gerson therapy and its coffee enemas, for instance:
START OF QUOTE
…The Gerson Institute, along with many other high-profile alternative practitioners, prescribes coffee enemas to their patients up to five times per day in order to assist the liver in its mammoth task of detoxification and encouraging healthy bile production, which can further assist in breaking down toxins and cleansing the body.
It might sound a little wacky (and more than a little uncomfortable!), but the continuing popularity of coffee enemas suggests that it may be worth giving them a go if you’re suffering from stubborn health problems or planning on starting a detox diet…
Here are some of the reasons why you might want to try a coffee enema for yourself:
You’ve probably already guessed by now that helping the liver to eliminate toxins from the body is the main reason why coffee enemas are so popular these days. The fact is, we live in an increasingly toxic world, surrounding ourselves in machines that spew forth toxic fumes, food that introduces increasing levels of harmful chemicals and excesses of vitamins and minerals, and chronic stress which tricks our bodies into retaining toxins rather than expelling them.
Eventually, something’s gotta give — it’s either your liver or the toxins (hint: it’s usually the liver). Liver failure is often accompanied by other serious health conditions, with anything from diabetes to cancer as possible outcomes. Coffee enemas bypass the digestive acids of the stomach, thereby delivering higher concentrations of caffeine to the colonic walls and stimulating greater bile secretion. This greatly helps the liver break down and eliminate toxins, a process which is marked by reduced gastrointestinal and liver pain, and a clearing of those Herxheimer symptoms.
Promote a healthy digestive tract
Over time, our digestive system can start to get a bit “down in the dumps” (pun intended). Bits of food waste can accumulate in the colon, along with toxins and other harmful compounds that stick to the colonic walls and can begin to degrade the overall health of your digestive tract. Coffee enemas, by stimulating bile secretion, help to purge the colon of that accumulated debris. This is helped by the physical flushing of fluids through the colon in the opposite direction, along with the enema encouraging greater peristalsis. Peristalsis refers to the wave-like contractions that help to move your food from one end to the other. More peristalsis means more movement of food wastes… and toxins.
Ease bloating and stomach pain
Bloating, gas and stomach pain are usually signs that your digestive system is underperforming. This is often due to a lack of bile secretion, poor food transit time and an overloaded liver… all of which are improved via coffee enemas! By using coffee enemas, you’re likely to see a marked improvement in your digestive issues, with less bloating, upset stomachs and gas.
Hundreds of recent studies have found a strong link between the gut and our mood. That link, referred to as the gut-brain axis, proves that a healthy gut is associated with a healthy state of mind. When your digestive system (and therefore gut) is overloaded with toxins, you’re bound to feel depressed and constantly suffering from negative emotions. Clearing up your toxin problem with a regular coffee enema should help to improve your mood and alleviate depression.
Candida is one of the biggest problems facing Americans today. It’s a stubborn form of yeast that resides in the gut (along with the mouth and, er, lady bits) and wreaks havoc with your immune system. Not only that, candida overgrowth contributes to insatiable sugar cravings, which in turn causes the overgrowth to establish itself more firmly.
Coffee enemas may selectively flush out candida overgrowths in the gut while preserving the beneficial bacteria that we rely on to break down food and support healthy immune function. Many people report a significant reduction in their symptoms of candida with regular coffee enema flushing.

The article where these quotes come from is entitled ‘5 REASONS TO TRY COFFEE ENEMAS’. I think it is only fair for me to respond by writing a (much shorter) comment entitled
5 REASONS TO AVOID COFFEE ENEMAS
- None of the claims made above is supported by good evidence.
- Enemas with or without coffee are far from pleasant.
- Enemas are not risk-free.
- Such treatments cost money which could be used for something sensible.
- Coffee taken via the other end of the digestive tract is a much nicer experience.
On this blog, we have often discussed the risks of spinal manipulation. As I see it, the information we have at present suggests that
- mild to moderate adverse effects are extremely frequent and occur in about half of all patients;
- serious adverse effects are being reported regularly;
- the occur usually with chiropractic manipulations of the neck (which are not of proven efficacy for any condition) and often relate to vascular accidents;
- the consequences can be permanent neurological deficits and even deaths;
- under-reporting of such cases might be considerable and therefore precise incidence figures are not available;
- there is no system to accurately monitor the risks;
- chiropractors are in denial of these problems.
Considering the seriousness of these issues, it is important to do more rigorous research. Therefore, any new paper published on this subject is welcome. A recent article might shed new light on the topic.
The objective of this systematic review was to identify characteristics of 1) patients, 2) practitioners, 3) treatment process and 4) adverse events (AE) occurring after cervical spinal manipulation (CSM) or cervical mobilization. A systematic searches were performed in 6 electronic databases up to December 2014. Of the initial 1043 articles thus located, 144 were included, containing 227 cases. 117 cases described male patients with a mean age of 45 and a mean age of 39 for females. Most patients were treated by chiropractors (66%). Manipulation was reported in 95% of the cases, and neck pain was the most frequent indication for the treatment. Cervical arterial dissection (CAD) was reported in 57% of the cases and 45.8% had immediate onset symptoms. The overall distribution of gender for CAD was 55% for female. Patient characteristics were described poorly. No clear patient profile, related to the risk of AE after CSM, could be extracted, except that women seemed more at risk for CAD. The authors of this review concluded that there seems to be under-reporting of cases. Further research should focus on a more uniform and complete registration of AE using standardized terminology.
This article provides little new information; but it does confirm what I have been saying since many years: NECK MANIPULATIONS ARE ASSOCIATED WITH SERIOUS RISKS AND SHOULD THEREFORE BE AVOIDED.
This post is based on an article by Ken Harvey, Associate Professor, School of Public Health and Preventive Medicine, Monash University, Australia. I took the liberty of slightly modifying his text for the purpose of this blog. The article informs us about the regulation of nonsense which, as I have often argued, is likely to result in nonsense.
Australia’s drugs regulator seems to be endorsing unfounded claims about homeopathy and traditional Chinese medicine as part of its review of how complementary medicines are regulated. In the latest proposed changes, the Therapeutic Goods Administration (TGA) is looking at what suppliers can claim their products do, known as “permitted indications”. An example of a “low level” permitted indication might be “may relieve the pain of mild osteoarthritis”.
If approved, suppliers will be able to use the permitted indication to market their products. The resulting problem is obvious. For instance, despite the TGA’s Complaints Resolution Panel upholding complaints of a lack of evidence that magnesium and homeopathy “relieve muscle cramps (and restless legs)”, this permitted indication is on its draft list. Other examples of dodgy claims include “supports transport of oxygen in the body”, “regulates healthy male testosterone levels”. The list contains around 140 traditional Chinese medicine indications, such as “Harmonise middle burner (Spleen and Stomach)”, “Unblock/open/relax meridians”, “Balance Yin and Yang”. None of them have any basis in fact or science. There are also around 900 additional indications for unspecified “traditions”.
Traditional medicines are not necessarily safe, as emerging data highlights how common adverse reactions and drug interactions really are. For example, Hyland’s homeopathic baby teething products were recalled by the US Food and Drug Administration and then the TGA because they contained high levels of belladonna alkaloids which caused adverse events in hundreds of babies. In China, out of the 1.33 million case reports of adverse drug event reports received by the National Adverse Drug Reaction Monitoring Center in 2014, traditional Chinese medicine represented around 17.3% (equivalent to around 230,000 cases).
Listed medicines are supposed to contain pre-approved, relatively low-risk ingredients. They should be produced with good manufacturing practice and only make “low-level” health claims for which evidence is held. However, the TGA does not check these requirements before the product is marketed. To safeguard shoppers, consumer representatives, suggested the proposed list of permitted indications should be short and only contain wordings such as, “may assist” or “may help”. For consumers to make an informed purchase, claims based on “traditional use” should always have a disclaimer along the lines of what the US Federal Trade Commission uses for homeopathic products. For example, “This product’s traditional claims are based on alternative health practices that are not accepted by most modern medical experts. There is no good scientific evidence that this product works”.
As I see it, the problem is that the evidence for many of the claims which are about to be allowed is either absent, seriously flawed or negative. Yet, the purpose of any regulation of this kind must be to protect consumers from purchasing ineffective and sometimes dangerous products. Regulators are keen to balance this aim against another aim: helping an industry to thrive. It is never easy to get such a balance right. But to allow nonsense, pseudoscience and overt falsehoods to creep in, must surely be wrong, unethical and illegal.
In my previous post, I reported that the NHS has included homeopathy and herbal medicine on the list of medications that might no longer get reimbursed. The news was reported by most newspapers in the UK. All of the papers correctly quote NHS England giving their reasons for black-listing homeopathy and herbal remedies. Some papers also quote critics of homeopathy providing short ‘sound bites’ and opinions. None of the articles bother to explain in any detail why homeopathy is so ridiculously implausible or how strong the evidence against it has become. In this post, I intend to analyse some of this press coverage by copying those excerpts from the newspaper articles which I find odd or misleading and by adding short comments by myself.
THE DAILY MAIL claimed that homeopathic remedies are treatments using heavily diluted forms of plants, herbs and minerals. This is factually incorrect; think of remedies like X-ray! The Mail also quoted Don Redding, director of policy at National Voices, stating: ‘Whilst some treatments are available to purchase over the counter, that does not mean that everyone can afford them. There will be distinct categories of people who rely on NHS funding for prescriptions of remedies that are otherwise available over the counter. Stopping such prescriptions would break with the principle of an NHS “free at the point of use” and would create a system where access to treatments is based on a person’s ability to pay.’ This argument might apply to medicines that are proven to work; it does, however, not apply to homeopathy.
THE INDEPENDENT cited Professor Helen Stokes-Lampard, chair of the Royal College of GPs, who said: “If patients are in a position that they can afford to buy over the counter medicines and products, then we would encourage them to do so rather than request a prescription – but imposing blanket policies on GPs, that don’t take into account demographic differences across the country, or that don’t allow for flexibility for a patient’s individual circumstances, risks alienating the most vulnerable in society.” Again, this argument might apply to medicines that are proven to work; it does, however, not apply to homeopathy.
THE DAILY TELEGRAPH also reported the quote from Don Redding, Director of Policy at National Voices which I cited above.
THE DAILY MIRROR quoted The Royal Pharmaceutical Society claiming that such a move raised “serious concerns” for poorer Brits. RPS England Board Chair Sandra Gidley said: “A blanket ban on prescribing of items available to buy will not improve individual quality of life or health outcomes in England. “Those on low incomes will be disproportionately affected.” THE MIRROR also reported what had to say and added that the NHS constitution states that: “Access to NHS services is based on clinical need, not an individual’s ability to pay; NHS services are free of charge, except in limited circumstances sanctioned by parliament.”
THE NEWS & STAR repeated the above quote from The Royal Pharmaceutical Society.
THE GUERNSEY PRESS repeated what RPS England board chair Sandra Gidley said: “We would encourage people with minor health problems to self-care with the support of a pharmacist and to buy medicines where appropriate and affordable to the individual. However, expecting everyone to pay for medicines for common conditions will further increase health inequalities and worsen the health of patients who cannot afford them. A blanket ban on prescribing of items available to buy will not improve individual quality of life or health outcomes in England. Those on low incomes will be disproportionately affected. They should not be denied treatment because of an inability to pay.”
THE TIMES also quoted the RPS and Don Redding misleadingly (see above and below) and concluded their article by citing Cristal Summer, chief executive of the British Homeopathic Association saying: Patients will be prescribed more expensive conventional drugs in place of homeopathy, which defeats the object of the exercise. The NHS also claims it wants to reduce the amount of prescription drugs patients take, then stops offering complementary therapies which can help achieve this. This clearly ignores the fact that ‘the object of the exercise’ for any health service must be to provide effective treatments and avoid placebo therapies like homeopathy.
THE SUN quoted The Royal Pharmaceutical Society saying such a move raised “serious concerns” for poorer Brits. But it said banning NHS-funded homeopathy was long overdue. THE SUN continued by citing John O’Connell, Chief Executive of the TaxPayers’ Alliance: “The NHS are absolutely right to look at removing homeopathy from their approved prescription list and it’s astonishing that it hasn’t happened sooner.”
METRO pointed out that actress Gwyneth Paltrow, ex-Beatle Paul McCartney and world record sprinter Usain Bolt are all known to swear by homeopathic remedies.
Generally speaking, the newspaper coverage was not bad, in my view. The exception evidently is THE TIMES (see above). Several other articles also have a slight whiff of false balance, introducing seemingly rational counter-arguments where none exist. Even though the headlines invariably focus on homeopathy, some of the quotes used by the papers are clearly about other medicines black-listed. This seems particularly obvious with the quotes by the RPS. Many readers might thus be misled into thinking that there is opposition by reputable organisations to the ban on homeopathy. None of the articles that I read quoted a homeopath at the end saying something like WE KNOW OF MANY PATIENTS WHOSE LIVES WERE SAVED BY HOMEOPATHY. JUST BECAUSE WE DON’T UNDERSTAND HOW IT WORKS DOES NOT MEAN IT DOES NOT WORK. A BAN WOULD PUT PUBLIC HEALTH AT RISK.
Only a few years ago, this type of conclusion to an article on homeopathy would have been inevitable! Could it be that UK journalists (with the exception of those at THE TIMES?) are slowly learning?
The Daily Star reported that 9 children have died in Tripura Para of Sitakunda during the last week. At least 46 other children in the remote hilly area are suffering from the same unidentified disease which has not yet been identified. The children aged between one and 12 suffer from fever and other symptoms include body rash, breathing problems, vomiting and blood in stool.
None of the fatalities was taken to a hospital, and two of them were treated homeopathically. The three-year-old Rupali had fever and a rash all over her body for three days. “We took her to a man who practices homeopathy. He lives some two kilometres away. He had given Rupali some medicines”, said her uncle. Asked why they did not take the child to a hospital, Pradip said the next health complex was 15 kilometres away from their home. Besides, they did not have money to buy medicines which would have been prescribed by doctors.
Shimal Tripura was also among the children who died. His father Biman Tripura said the two-year-old boy had been suffering from fever for six days. Shimal was also taken to a local man who practices homeopathy.
“The disease could not be identified immediately,” said a spokesperson. Asked whether the disease could be transmitted by mosquitoes, he said, “It does not seem so. If it was, then why only children were being affected?” A medical team from the Institute of Epidemiology, Disease Control and Research in Dhaka was dispatched for Sitakunda, he said, adding that the local primary school was shut down to prevent the spread of the disease.
I have often pointed out that homeopathy can be deadly – not usually via its remedies (highly diluted homeopathic have no effects whatsoever) but via homeopaths who do not know what they are doing. It seems that here we have yet further tragic cases to confirm this point. Nine children were reported to have died. Two of them received homeopathic remedies and 7 seemed to have had no treatment at all. This looks like a very sad statistic indicating that homeopathy is as bad as no treatment at all.
Isn’t it wonderful when your long-held views are confirmed by someone with influence?
This, of course, is a rhetorical question – I can tell you: it is wonderful!
The multibillion-dollar market for “natural” health products has flourished under lax government regulations. These regulations have enabled manufacturers to exploit the public’s difficulty in distinguishing nonprescription drugs, with scientifically proven therapeutic benefits, from herbal or homeopathic preparations and supplements that often make similar health claims with little or no evidence and are frequently grounded in unscientific belief systems about health and disease…
In pharmacies, supermarkets and convenience stores, natural health products are displayed side by side with nonprescription drugs. Both tout their approval by Health Canada as an implicit endorsement of efficacy and safety on package labels that make similar health claims. However, although nonprescription drugs and their therapeutic claims require scientific evidence that is carefully scrutinized by Health Canada, natural health products have a separate regulatory system that typically imposes such minimal requirements that it is effectively a rubber stamp. Unlike nonprescription drugs, if a problem arises with a natural health product, Health Canada has little or no authority to compel any changes to its manufacture, labelling or sale.
…Risk is often difficult to perceive accurately without direct evidence. For example, under the proposed framework, Health Canada would continue to classify most homeopathic preparations as low-risk products and, thus, exempt from scientific review. Recently, a homeopathic product sold in the United States that claimed to relieve teething pain in infants and supposedly contained a very dilute extract from the belladonna plant was associated with several deaths of infants who manifested classic signs of anticholinergic poisoning…
…If consumers are unable to separate products with no scientific proof behind them from products supported by evidence, then we need to separate them in stores. Natural health products should be pulled from the shelves where they are mixed with nonprescription drug products and confined to their own separate section, away from any signage implying a therapeutic use.
The double standard perpetuated by both regulators and retailers that enables the deception of unsuspecting Canadians must end. Alternative medicines with claims based on alternative facts do not deserve an alternative, easy regulatory road to market — at the very least, they need to be moved to an alternative shelf.
END OF QUOTES
This, of course, is Canada. But elsewhere progress is also being made.The Australian reported about plans in Australia whereby pharmacies would be banned from selling useless and possibly dangerous homoeopathic remedies. The Australian last year revealed a review of pharmacy regulation, headed by Stephen King from the Productivity Commission, identified a potential conflict of interest in pharmacists selling vitamins, for example, that may not have a significant evidence base, alongside more stringently regulated and government-subsidised medicines. In its interim report, the review panel was “concerned that the sale of complementary medicines alongside other medicines may mislead consumers”. It therefore concludes that “complementary medicines should be held in a separate area within community pharmacies, where customers can easily access a pharmacist for appropriate advice.”
“To avoid potential harm, or the confusion between the efficacies of different types of medicines, pharmacists need to be easily accessible to give needed advice when consumers choose a complementary or pharmacy-only medicine,” the review panel said. It was scathing of homoeopathy and the perception of legitimacy given to those so-called remedies sold in pharmacies. “The only defence put to the panel regarding homoeopathy was that it was harmless and able to be used as a placebo in certain circumstances,” the review panel noted. “The panel does not believe that this argument is sufficient to justify the continued sale of these products in pharmacies …”
AUSTRALIAN JOURNAL OF PHARMACY (AJP) noted that the interim report of the Review of Pharmacy Remuneration and Regulation states that “there are unacceptable risks where community pharmacies are allowed to sell homeopathic products”.
In 2015 Pharmaceutical Society of Australia (PSA) said it did not support the sale of homeopathy in pharmacy. “Our position is that pharmacists must use their professional judgement to prevent the supply of products with evidence of no effect,” PSA president Joe Demarte said at the time. Ian Carr, of Saxby’s Pharmacy in Taree, NSW, and Friends of Science in Medicine member, told the AJP that “in terms of homeopathic products being recommended not to be sold by PBS-approved pharmacies, I one hundred per cent heartily agree with that finding. “I love saying that I believe homeopathy works. But it has never been shown to work better than placebo. There are many things that will work as well as placebo, but it’s not ethical to be selling them as a cure or treatment for something. I would have a bit more time for it if there was a plausible theory behind it, but its basis is entirely implausible – it pushes all the buttons for being a pseudoscience, so I agree it has no place in Australian pharmacy. However, I am at a bit of a loss to understand why they haven’t carried some of that logic over into the comments on complementary medicines generally.”
Mr Carr also told the AJP that “If one conceives of complementary medicines as being vitamins and minerals, that’s one thing. But the marketing of those items has become so diffuse and so wide that on most of these CM shelves we have traditional medicines, we’ve got herbal medicines, we’ve got items that are basically just marketing formulas for certain conditions. The evidence behind most of these things is very very slim, and we still have the possibility of health fraudsters just marching in and taking advantage of the lack of regulation in the industry.”
So, Canada and Australia are making progress in protecting consumers from bogus healthcare products and from pharmacists selling them.
When, I ask myself, are the UK, the US and other countries following suit?
I was surprised to receive this email yesterday: “Hello Edzard Ernst, You may remember I got in touch last week regarding losing a loved one to the ravages of drugs or alcohol. I just wanted to remind you that Narconon is here to help. For over fifty years Narconon drug and alcohol rehabilitation centres have been successfully reversing the tide of addiction for men and woman from all walks of life. The Narconon programme has saved them from the misery of addiction, and the potential of an early grave. We not only address the cause of the addiction, we resolve them…”
The email was signed by a man from ‘Narconon International’. First I thought someone has been counting the empty bottles in my bin, then I read it again and noticed the word ‘NARCONON’ and remembered that I once wrote about it. A quick search located my article from THE GUARDIAN 2012:
Imagine a therapy that “enables an individual to rid himself of the harmful effects of drugs, toxins and other chemicals that lodge in the body and create a biochemical barrier to spiritual well-being“. If you were told that the treatment was entirely natural and had already “enabled hundreds of thousands to free themselves from the harmful effects of drugs and toxins and so achieve spiritual gains”, wouldn’t you be tempted to try it?
Who doesn’t want a body free of nasty chemicals? And who wouldn’t be delighted at the chance to counter a growing threat to an “advancement in mental … wellbeing”?
These claims are being made for the “Purification Rundown” (“Purif” for short) and the closely related Narconon detox programmes, which mainly consist of regular exercise, sauna and nutrition, with industrial doses of vitamins and minerals added for good measure. Some of the claims are quite specific: the Purif programme is supposed to increase your IQ, reduce the level of cancer-causing agents in your body, and even enable you to lose weight easily and quickly. The Narconon programme is more specifically targeted at drug and alcohol dependency and is claimed to have an impressive success rate of 75%.
Both programmes were developed by L Ron Hubbard (1911-1986) and are currently marketed by the Church of Scientology. The CoS is not generally known to be an organisation that promotes healthcare programmes. Hubbard, the pulp-fiction writer who founded the CoS, portrayed himself somewhat over-optimistically as a pioneer, innovator and nuclear physicist.
He taught his followers that, at their core, humans contain a “thetan”. After creating the universe, thetans accidentally became trapped in physical bodies and, through scientology, we can restore the immortal, omnipotent, god-like powers of the “thetan” within us. Weird stuff that is the preserve of Hollywood eccentrics, you might think, but perhaps the CoS’s detox-ventures are an attempt to conquer new territory?
A typical course of treatment lasts several weeks and consists of many hours of exercise and sauna every day. This regimen is supplemented with megadoses of vitamins and minerals, which can cause problems. Niacin, one vitamin that is given in high doses as part of the regimen, can be particularly dangerous. The US National Institutes of Health warns that at high doses it can cause “liver problems, gout, ulcers of the digestive tract, loss of vision, high blood sugar, irregular heartbeat, and other serious problems.” It should not be taken by people who already have liver damage.
Seven fatalities of people undergoing the Narconon programme are currently being investigated in Oklahoma, although the CoS says these deaths are not connected with the treatment regimen itself.
Whatever the truth regarding these deaths, a review of the evidence about the treatment regimen’s effectiveness – carried out by the Norwegian Knowledge Centre for the Health Services in 2008 – found no good evidence that the Narconon programme works:
There is currently no reliable evidence for the effectiveness of Narconon as a primary or secondary drug prevention program. This is partly due to the insufficient research evidence about Narconon and partly due to the non-experimental nature of the few studies that exist.
The claim that such detox treatments eliminate toxins from the body is, of course, easily testable. All we would need to do is define what toxin we are talking about and measure the change in levels of that toxin compared with a control group of volunteers who did not receive the detox.
But such studies are not available. Why? Do the marketing men believe in their own claims? Maybe they feel that profits and evidence are like fire and water? Or possibly the thetans have an aversion to science?
If you think that the Purif, Narconon or any other form of alternative detox eliminates toxins, you might be mistaken. Most clients have lost some money, many have lost their ability to think straight, some may even have lost their lives. But there is no reliable evidence that they have actually lost any toxins.
END OF MY 2012 ARTICLE
In 2012, I found no evidence to suggest that NARCONON works. Now, I looked again and found this article reporting a non-randomised, controlled study:
“In 2004, Narconon International developed a multi-module, universal prevention curriculum for high school ages based on drug abuse etiology, program quality management data, prevention theory and best practices. We review the curriculum and its rationale and test its ability to change drug use behavior, perceptions of risk/benefits, and general knowledge. After informed parental consent, approximately 1000 Oklahoma and Hawai’i high school students completed a modified Center for Substance Abuse Prevention (CSAP) Participant Outcome Measures for Discretionary Programs survey at three testing points: baseline, one month later, and six month follow-up. Schools assigned to experimental conditions scheduled the Narconon curriculum between the baseline and one-month follow-up test; schools in control conditions received drug education after the six-month follow-up. Student responses were analyzed controlling for baseline differences using analysis of covariance. At six month follow-up, youths who received the Narconon drug education curriculum showed reduced drug use compared with controls across all drug categories tested. The strongest effects were seen in all tobacco products and cigarette frequency followed by marijuana. There were also significant reductions measured for alcohol and amphetamines. The program also produced changes in knowledge, attitudes and perception of risk. The eight-module Narconon curriculum has thorough grounding in substance abuse etiology and prevention theory. Incorporating several historically successful prevention strategies this curriculum reduced drug use among youths.”
The question arises: would I send anyone to the NARCONON programme?
My answer is NO!
Not because the trial is lousy (which it is) and not because the programme is too expensive (which it is); I would not send anyone to any institution that has even the slightest links to Scientology.
Dr Gabriella Day is a GP in England who describes herself and her beliefs as follows: “I began training in homeopathy as it is clear that for many conditions conventional treatment options are not effective and can have unwanted side effects. It seemed to me that there must be another way to help people suffering from symptoms such as these… I believe in whole person medicine. No illness exists in isolation. The human body is immensely sophisticated and complicated and we do not understand it fully. Therefore the illness cannot be separated from the person suffering the disease. This may be as simple as stress impairing the immune system to far more complex interactions. Homeopathic treatment seeks to match the underlying disturbance in the system and stimulate the body to correct itself.”
I do not know Dr Day, but she caught my attention recently when she published an article in THE HIPPOCRATIC POST (I had never heard of this publication before!). It is, I think, sufficiently noteworthy to show you some excerpts (the references [in square brackets] were added by me, and they refer to my comments below):

…Homeopathy can be helpful for pretty much any condition , whether as the main treatment , as a complement to a conventional treatment  to speed up the healing process , or to lessen the side-effects of a pharmacological medication . It can be helpful in the treatment of emotional problems , physical problems  and for multi-morbidity patients . I find it an invaluable tool in my GP’s toolbox and regularly see the benefits of homeopathy in the patients I treat …
There are many conditions for which I have found homeopathy to be effective … There are, however, a multitude of symptomatic treatments available to suppress symptoms, both on prescription and over-the-counter. Most symptoms experienced by patients in this context result from the body’s attempt to eliminate the infection. Our immune systems have spent thousands of years refining this response; therefore it seems counter-intuitive to suppress it .
For these types of acute conditions homeopathy can work with the body to support it . For instance, homeopathic Arsenicum album (arsenic) is a classic remedy for diarrhoea and vomiting that can be taken alongside essential oral rehydration . And in influenza I’ve found Eupatorium perfoliatum (ague or feverwort) to be very helpful if the patient is suffering with bony pain .
…Unless it is clinically imperative for a pharmacological intervention, I will always consider homeopathy first  and have successfully prescribed the homeopathic remedy Nux vomica (strychnine) for women suffering from morning sickness . Problems associated with breastfeeding such as mastitis have also responded well to the classic remedies Belladonna (deadly nightshade) and Phytolacca (pokeweed), while I have found Urtica urens (dog nettle) effective in switching off the milk supply to prevent engorgement when the mother stops breastfeeding .
…“heart sink” patients are clearly suffering from pain and discomfort, which is blighting their lives. This is understandably frustrating for them, for they know full well something is awry but there is no medical evidence for this… Homeopathy affords me another approach in trying to help these patients [1,3]. It doesn’t work for them all, but I’m frequently surprised at how many it does help .
The beauty of homeopathy is that it combines mental and emotional symptoms with physical symptoms . When the right remedy is found it appears to stimulate the body to recognise how it is being dysfunctional and corrects this, with no suppression, just a correction of the underlying disturbance . Thus homeopathy not only eliminates unwanted symptoms , it dramatically improves a patient’s overall well-being .
…homeopathy… enables me to reduce the number of painkillers and other drugs I’m prescribing [1,3]. This is particularly true for older multi-morbidity, polypharmacy patients  who are often taking huge amounts of medication.
Contrary to what most homeopaths will tell you, I believe homeopathic treatment does have side-effects – positive side-effects!  It fosters an enhanced doctor patient relationship . The process of eliciting the relevant information to select a remedy enables me to better understand the patient’s condition and helps me to get to know them better . And the patient, seeing that the doctor is interested in the idiosyncrasies and detail of their disease, finds themselves heard and understood . In short, since training in homeopathy I enjoy my job as a GP and my relationship with patients so much more .

- statement without good evidence,
- Hahnemann was vehemently against combining homeopathy with other treatments and called clinicians who disregarded this ‘traitors’,
- statement of belief,
- wrong assumption,
- questionable ethics.
I have recently attempted to slip into the brain of lay-homeopaths and shown how illogical, misguided and wrong the arguments of such enthusiasts really are. Surely, the logic of a doctor homeopath must be better, I then thought. Once you have studied medicine, you have learnt an awful lot of things about the body, disease, therapy, etc., etc., I felt.
Judging from the above article, I might have been wrong.
The ‘Daily Mail’ is not a paper famed for its objective reporting. In politics, this can influence elections; in medicine, it can endanger public health.
A recent article is a case in point, I think.

Traditional Chinese medicines could help prevent heart disease and the progression of pre-diabetes, according to research. Some herbal treatments proved as effective in lowering blood pressure as Western drugs and improved heart health by lowering cholesterol, scientists found. Certain alternative medicines could lower blood sugar and insulin levels, too.
Chinese medicines could be used alongside conventional treatments, say researchers from Shandong University Qilu Hospital in China. Or they can be beneficial as an alternative for patients intolerant of Western drugs, they said in their review of medical studies over a ten-year period. Senior review author from the university’s department of traditional Chinese medicine said: ‘The pharmacological effects and the underlying mechanisms of some active ingredients of traditional Chinese medications have been elucidated. Thus, some medications might be used as a complementary and alternative approach for primary and secondary prevention of cardiovascular disease.”
It’s potentially good news for people living with diabetes, which is now a global epidemic and has proved a tricky condition to manage for many people. High blood pressure is very common too, affecting more than one in four adults in the UK, although many won’t show symptoms and realise it. If untreated, it increases your risk of serious problems including heart disease, the number one killer globally.
The Chinese have used herbs for treating diseases for thousands of years and have become increasingly popular in Europe and North America, mainly as complement to Western medicine. But the researchers also warn that much of the research conducted have limitations and so their long-term effects are not proven.
Herbs for high blood pressure
The blood pressure-lowering effect of herb zhongfujiangya was found to be similar to that of oral anti-hypertension medication benazeprilm, which goes by the brand name Lotensin. Similarly, patients treated for eight weeks with herbal tiankuijiangya had a lower reading than those given a placebo. Herbal Jiangya tablets were found to ‘significantly lower’ systolic blood pressure, that is the amount of pressure in your arteries during contraction of your heart muscle compared to a fake treatment. The herb Jiangyabao also had a significant effect compared to a placebo, but just at night. But overall, compared to the drug Nimodipine, a calcium channel blocker, it worked just as well. Qiqilian capsules also proved more effective compared to a placebo.
Herbs for diabetes
The team report some Chinese medicines medications – such as xiaoke, tangminling, jinlida, and jianyutangkang – have a ‘potent’ effect on lowering blood sugar levels and b-cell function, which controls the release of insulin. Some remedies – such as tangzhiping and tianqi – might prevent the progression of pre-diabetes to diabetes, they note.
Herbs for cholesterol
The researchers looked at research on dyslipidemia, the term for unbalanced or unhealthy cholesterol levels. They found that jiangzhitongluo, salviamiltiorrhiza and pueraria lobata, and zhibitai capsule all have a ‘potent lipid-lowing effect’.
Herbs for heart disease
Some traditional Chinese medicines such as qiliqiangxin, nuanxin, shencaotongmai, and yangxinkang, might be effective in improving function in patients with chronic heart failure, they wrote.
Limitations with trials
But Western scientists often reject Chinese medicine for specific reasons, warned Dr Zhao’s team. Chinese medicines are frowned upon because they do not go through the same exhaustive approval process as trials conducted domestically, they pointed out. Plus, one treatment can be made of many different ingredients with various chemical compounds, making it hard to pinpoint how their benefits work. ‘One should bear in mind that traditional Chinese medicine medications are usually prescribed as complex formulae, which are often further manipulated by the practitioner on a personalized basis,’ said Dr Zhao.

Apart from the fact that this article is badly written, it is also misleading to the point of being outright dangerous. Regular readers of my blog will be aware that Chinese research is everything but reliable; there are practically no Chinese TCM-trials that report negative results. Furthermore, the safety of Chinese herbal preparations is as good as unknown and they are often contaminated with toxic substances as well as adulterated with synthetic drugs. Most of these preparations are also unavailable outside China. Moreover, Chinese herbal treatments are usually individualised (mixtures are tailor-made for each individual patient), and there is no good evidence that this approach is effective. Crucially, the trial evidence is often of such poor quality that it would be a dangerous mistake to trust these findings.
None of these important caveats, it seems, are important enough to get a mention in the Daily Mail.
Don’t let the truth get in the way of a sensational story!
Let’s just for a moment imagine what would happen if people took the Mail article seriously (is there anyone out there who does take the Mail seriously?). In a best case scenario, they would take Chinese herbs in addition to their prescribed medication. This might case plenty of unwanted side-effects and herb-drug interactions. In addition, people would lose a lot of their hard-earned cash. In a worst case scenario, they would abandon their prescribed medication for dubious Chinese herbal mixtures. This could cause thousands of premature deaths.
With just a little research, I managed to find the original article on which the Mail’s report was based. Here is its abstract:
Traditional Chinese medicine (TCM) has more than 2,000 years of history and has gained widespread clinical applications. However, the explicit role of TCM in preventing and treating cardiovascular disease remains unclear due to a lack of sound scientific evidence. Currently available randomized controlled trials on TCM are flawed, with small sample sizes and diverse outcomes, making it difficult to draw definite conclusions about the actual benefits and harms of TCM. Here, we systematically assessed the efficacy and safety of TCM for cardiovascular disease, as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and potential mechanisms. Results indicate that TCM might be used as a complementary and alternative approach to the primary and secondary prevention of cardiovascular disease. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.
In my view, the authors of this review are grossly over-optimistic in their conclusions (but nowhere near as bad as the Mail journalist). If the trials are of poor quality, as the review-authors admit, no firm conclusions should be permissible about the usefulness of the therapies in question.
As the Mail article is obviously based on a press release (several other papers worldwide reported about the review as well), it seems interesting to note what the editor of the Journal of the American College of Cardiology (the journal that published the review) recently had to say about the responsibility of journalists and researchers:
START OF QUOTE
…I would like to suggest that journalists and researchers must share equally in shouldering the burden of responsibility to improve appropriate communication about basic and clinical research.
First, there is an obligation on the part of the researchers not to inflate the importance of their findings. This has been widely recognized as damaging, especially if bias is introduced in the paper…
Second, researchers should take some responsibility for the creation of the press release about their research, which is written by the media or press relations department at their hospital or society. Press releases are often how members of the media get introduced to a particular study, and these releases can often introduce errors or exaggerations. In fact, British researchers evaluated 462 press releases on biomedical and health-related science issued by 20 leading U.K. universities in 2011, alongside their associated peer-reviewed research papers and the news stories that followed (n = 668). They found that 40% of the press releases contained exaggerated advice, 33% contained exaggerated causal claims, and 36% contained exaggerated inference to humans from animal research. When press releases contained such exaggeration, 58%, 81%, and 86% of news stories, respectively, contained further exaggeration, compared with rates of 17%, 18%, and 10% in the news when the press releases were not exaggerated. Researchers should not be excused from being part of the press release process, as the author(s) should at least review the release before it gets disseminated to the media. I would even encourage researchers to engage in the process at the writing stage and to not allow their hospital’s or society’s public relations department to extrapolate their study’s results. Ultimately, the authors and the journals in which the studies are published will be held accountable for the information that trickles into the headlines, not the public relations departments, so we must make sure that the information is accurate and representative of the study’s actual findings.

Sound advice indeed.
Now we only need to ALL follow it!!!
