Alternative practitioners practise highly diverse therapies. They seem to have nothing in common – except perhaps that ALL of them are allegedly stimulating our self-healing powers (and except that most proponents are latently or openly against vaccinations). And it is through these self-healing powers that the treatments in question cure anything and become a true panacea. When questioned what these incredible powers really are, most practitioners would (somewhat vaguely) name the immune system as the responsible mechanism. With this post, I intend to provide a short summary of the evidence on this issue:
Acupuncture: no good evidence to show stimulation of self-healing powers.
Aromatherapy: no good evidence to show stimulation of self-healing powers.
Bioresonance: no good evidence to show stimulation of self-healing powers.
Chiropractic: no good evidence to show stimulation of self-healing powers.

Vibrational therapy: no good evidence to show stimulation of self-healing powers.
Vaccinations: very good evidence to show stimulation of self-healing powers.
Traditional vaginal practices usually relate to personal hygiene, genital health or sexuality. Hygiene practices involve external washing and intravaginal cleansing or douching and ingestion of substances. Health practices include intravaginal cleansing, traditional cutting, insertion of herbal preparations, and application of substances to soothe irritated vaginal tissue.
One such traditional practice is ‘vaginal steaming’.
Recently vaginal steaming has become a fad promoted by SCAM-promoters (such as the vagina-obsessed Gwyneth Paltrow) with the claim that it leads to a range of health benefits. According to one website, for instance, vaginal steaming, Yoni Eggs, yoni or v-steam, as it is casually known, acts as an internal cleanser of the membranes of the vaginal tissues and uterus. This is considered especially important for stagnant fertility conditions and/or incomplete emptying of menses each cycle. This women’s treatment gently but effectively cleanses, tones and revitalizes a woman’s center, providing a myriad benefits from reduced menstrual cramps to increased fertility and more. Support your natural feminine cycle, help your body to heal, relax, and detoxify both physically and emotionally with a yoni steam.
The method is recommended for a wide range of conditions and is said to achieve all of the following and much, much more:
- Significant reduction of pain, bloating and exhaustion associated with menstruation.
- Significant reduction of PMS.
- Decrease of menstrual flow as well as reduction of dark purple or brown blood at the onset or end of menses.
- Regulation of irregular or absent menstrual cycles.
- Increased fertility.
- Faster healing and toning of the reproductive system following childbirth.
- Assisting in healing uterine fibroids, ovarian cysts, uterine weakness, uterine prolapse & endometriosis.
- Breaking down of reproductive adhesion/scar tissue. Assisting with the repair of a vaginal tear, episiotomy, or C-section scar.
- Assisting with the healing of haemorrhoids.
- Treating chronic vaginal/yeast infections and maintaining healthy vaginal odour.
- Relief of menopausal symptoms such as vaginal dryness or pain during sex.
- Detoxification of the womb/removal of toxins from the body. Release of stored emotions.
- Reconnection with our female bodies and tapping into the sexual energy that is our creative potential.
Frequently, entrepreneurs recommend adding herbal or other ingredients. Herbs often used include:
- vaginal steaming arms your bank account;
- it disrupts the normal pH balance of the vagina;
- in turn, this increases the risk of fungal and bacterial infections;
- vaginal steaming can cause burns;
- with added herbs, it can cause allergies.
New Zealand psychologists analysed online accounts of vaginal steaming to determine the sociocultural assumptions and logics within such discourse, including ideas about women, women’s bodies and women’s engagement with such ‘modificatory’ practices. Ninety items were carefully selected from the main types of website discussing vaginal steaming: news/magazines; health/lifestyle; spa/service providers; and personal blogs. Within an overarching theme of ‘the self-improving woman’ the researchers identified four themes: (1) the naturally deteriorating, dirty female body; (2) contemporary life as harmful; (3) physical optimisation and the enhancement of health; and (4) vaginal steaming for life optimisation. The authors concluded that online accounts of vaginal steaming appear both to fit within historico-contemporary constructions of women’s bodies as deficient and disgusting, and contemporary neoliberal and healthist discourse around the constantly improving subject.
For the sake of ‘journalistic balance’, let’s give Gwyneth the last word about the benefits of vaginal steaming. She knows best because she has done it and was quoted uttering these profound and scientific views: “The first time I tried v-steaming, I was like, ‘This is insane’. My friend Ben brought me and I was like, ‘You are out of your f**king mind. What is this? But then by the end of it I was like, ‘This is so great.’ Then I start to do research, and it’s been in Korean medicine for thousands of years and there are real healing properties. If I find benefit to it and it’s getting a lot of page views, it’s a win-win.”
And who would or could argue with that?
I have often pointed out that, in contrast to ‘rational phytotherapy’, traditional herbalism of various types (e. g. Western, Chinese, Kampo, etc.) – characterised by the prescription of an individualised mixture of herbs by a herbalist – is likely to do more harm than good. This recent paper provides new and interesting information about the phenomenon.
Specifically, it explores the prevalence with which Australian Western herbalists treat menstrual problems and their related treatment, experiences, perceptions, and inter-referral practices with other health practitioners. Members of the Practitioner Research and Collaboration Initiative practice-based research network identifying as Western Herbalists (WHs) completed a specifically developed, online questionnaire.
Western Herbalists regularly treat menstrual problems, perceiving high, though differential, levels of effectiveness. For menstrual problems, WHs predominantly prescribe individualised formulas including core herbs, such as Vitex agnus-castus (VAC), and problem-specific herbs. Estimated clients’ weekly cost (median = $25.00) and treatment duration (median = 4-6 months) covering this Western herbal medicine treatment appears relatively low. Urban-based women are more likely than those rurally based to have used conventional treatment for their menstrual problems before consulting WHs. Only 19% of WHs indicated direct contact by conventional medical practitioners regarding treatment of clients’ menstrual problems despite 42% indicating clients’ conventional practitioners recommended consultation with WH.
The authors concluded that Western herbal medicine may be a substantially prevalent, cost-effective treatment option amongst women with menstrual problems. A detailed examination of the behaviour of women with menstrual problems who seek and use Western herbal medicine warrants attention to ensure this healthcare option is safe, effective, and appropriately co-ordinated within women’s wider healthcare use.
Apart from the fact, that I don’t see how the researchers could possibly draw conclusions about the cost-effectiveness of Western herbalism, I feel that this survey requires further comments.
There is no reason to assume that individualised herbalism is effective and plenty of reason to fear that it might cause harm (the larger the amount of herbal ingredients in one prescription, the higher the chances for toxicity and interactions). The only systematic review on the subject concluded that there is a sparsity of evidence regarding the effectiveness of individualised herbal medicine and no convincing evidence to support the use of individualised herbal medicine in any indication.
Moreover, VAC (the ‘core herb’ for menstrual problems) is hardly a herb that is solidly supported by evidence either. A systematic review concluded that, although meta-analysis shows a large pooled effect of VAC in placebo-controlled trials, the high risk of bias, high heterogeneity, and risk of publication bias of the included studies preclude a definitive conclusion. The pooled treatment effects should be viewed as merely explorative and, at best, overestimating the real treatment effect of VAC for premenstrual syndrome symptoms. There is a clear need for high-quality trials of appropriate size examining the effect of standardized extracts of VAC in comparison to placebo, selective serotonin reuptake inhibitors, and oral contraceptives to establish relative efficacy.
And finally, VAC is by no means free of adverse effects; our review concluded that frequent adverse events include nausea, headache, gastrointestinal disturbances, menstrual disorders, acne, pruritus and erythematous rash. No drug interactions were reported. Use of VAC should be avoided during pregnancy or lactation. Theoretically, VAC might also interfere with dopaminergic antagonists.
So, to me, this survey suggests that the practice of Western herbalists is:
- not evidence-based;
- potentially harmful;
- and costly.
In a nutshell: IT IS BEST AVOIDED.
The Internet is full of complete nonsense about alternative medicine, as we all know. Much of it could be funny – if it was not so extremely dangerous. Misinformation on health can (and I am afraid does) kill people. One of the worst BS I have seen for a long time is this article entitled ‘Here’s What Oncologists Won’t Tell You About Essential Oils’.
A few excerpts might be of interest:
START OF QUOTES
…The human body resonates at a frequency of 62-78 MHz and scientists believe that diseases start at 58 MHz. Many studies have shown that negative thoughts can reduce our frequency by 12 MHz, while positive thinking raises it by 10.
This means that there are many things that can affect our health in ways we can’t imagine.
According to the latest studies, essential oils can fight cancer thanks to their antibacterial properties and their ability to change the frequency we resonate at.
One of the scientists involved in the study, Bruce Tainio, developed a special Calibrated Frequency Monitor that measures the frequency of essential oils and how they affect us. M. Suhail, an immunologist, says that cancer develops when the DNA in our cells’ nucleus is corrupted.
Essential oils can correct this and repair the code, effectively improving our chances against the terrible disease…
In his book “The Body Electric”, R. O. Becker said that our bodies’ electronic frequency determines our health.
Even Nikola Tesla said that removing outside frequencies can make us more resistant against ailments, while Dr. Otto Warburg discovered over a century ago that our cells have a specific electrical voltage that can drop due to a various factors and trigger diseases such as cancer.
However, science has now discovered that essential oils with higher frequencies can destroy diseases with lower frequencies.
Here’s a list of some of the oils used in the research and their electrical frequencies:
- Juniper – 98 Mhz
- Angelica – 85 Mhz
- Frankincense – 147 MHz
- Rose – 320 Mhz.
- Sandalwood – 96 Mhz
- Helichrysum – 181 MHz
- Peppermint – 78 Mhz
- Lavender – 118 Mhz
In the study, cinnamon, thyme, jasmine and chamomile oils had the best results when put up against breast cancer cells. Chamomile destroyed 93% of the cells in vitro, while thyme destroyed 97% of the cells…
11 oils were examined in total including bitter and sweet fennel, winter savory, peppermint, sage, lavender, chamomile and thyme.
According to Suhail, frankincense oil can divide the nucleus of cancer cells from the cytoplasm and prevent it from reproducing. The oil works thanks to the presence of the so-called monoterpenes which have the ability to kill cancer cells.
Frankincense oil works in all stages of cancer and is cytotoxic, meaning it doesn’t destroy healthy cells.
End-stage liver cancer patient
In the study, a patient with end-stage liver cancer was given only a few months left to live. The tumor was inoperable due to the large size, so having nothing to lose, the man decided to try frankincense oil.
He applied a bit under his tongue and topically on the area of the liver, and on his next doctor visit, the tumor has already reduced in size. The patient continued using frankincense oil, and it eventually reduced just enough to be operable. His tumor was later removed and the man is now happily enjoying his life free of cancer.
A child with brain cancer
One of the toughest cases among all the patients in the study was a little girl aged 5 with brain cancer. After exhausting all other options, the parents decided to give the girl a mixture of frankincense and sandalwood oil.
They rubbed the mixture on her feet while also rubbing a bit of lavender on her wrist. After a few months, the cancer was completely defeated!
Bladder cancer patient
Jackie Hogan is a woman suffering from bladder cancer who needed to undergo a surgery for bladder removal due to the cancer.
However, she decided to try using essential oils in her condition and after a few months of applying a mixture of sandalwood and frankincense oil topically on the area, she is cancer-free.
Stage-4 cancer patient
One woman in the research was diagnosed with stage-4 lung cancer which has already spread to other organs in her body.
Instead of agreeing to chemo and surgery, the woman started applying a bit of frankincense oil topically on the affected areas of her body every 2-3 hours and she was completely healthy in 7 months.
Breast cancer patient
A woman diagnosed with advanced breast cancer used a mixture of frankincense and lemongrass oil (topically and under the tongue) to defeat the disease in only a few months.
Cervical cancer patient
A woman with cervical cancer was given only a few months left to live, but thanks to the powers of frankincense oil, she managed to defeat the diseases in a couple of months.
There are many more patients who have managed to defeat different types of cancer using the remarkable powers of various essential oils…

I managed to find 4 of the studies this article seems to refer to:

I do not think that these papers actually show what is claimed above. Specifically, none of the 4 articles refers to clinical effects of essential oil on cancer patients. In fact, according to a 2014 review, and a 2013 paper (the most recent summaries I found) there are no clinical trials of essential oil as a cure for cancer.
The conclusion therefore must be this: Essential oils might be an interesting area of research, yet one has to tell consumers and patients very clearly:
there is no evidence to suggest that using essential oils will change the natural history of any type of cancer.
‘HELLO’ is, of course, a most reliable source of information when it comes to healthcare (and other subjects as well, I am sure). Therefore, I was thrilled to read their report on Meghan Markle’s list of supplements which, ‘HELLO’ claim, she takes for “calming any stress or nerves ahead of the royal wedding on 19 May.” The list includes the following:
- Vitamin B-12,
- ‘Cortisol Manager’ (30 tablets cost US$ 65)
Not only does ‘HELLO’ provide us with this most fascinating list, it tells us also what exactly these supplements are best used for:
Magnesium helps to keep blood pressure normal, increase energy, relieves muscle aches and spasms, and calms nerves, all of which will be beneficial to Meghan. Meanwhile, B12 drops will ensure Meghan doesn’t become deficient in the vitamin due to her diet, which is largely plant-based and contains very little animal products, which are one of the main sources of B12.
A multivitamin will provide Meghan with her recommended daily intake of various vitamins and minerals, while Cortisol Manager is a “stress hormone stabiliser”, which is designed to support the body’s natural rise and fall of cortisol, helping promote feelings of relaxation and aid better sleep. The supplement contains L-Theanine, Magnolia, Epimedium and Ashwagandha – although Meghan said she sometimes takes additional doses of the herb, likely at periods of high stress.
Ashwagandha is a herb that helps to moderate the body’s response to stress, bringing inner calm and also boosting energy. The supplement comes from the root of the ashwagandha plant and can be taken in tablet form…
I hope I don’t spoil the Royal wedding if I run a quick reality check on these supplements. Assuming she is generally healthy (she certainly looks it), and now being aware that Meghan eats a mostly plant-based diet, here are the most likely benefits of the above-listed supplements/ingredients:
- Magnesium: NONE
- Vitamin B-12: DEBATABLE
- Multivitamins: NONE
- L-Theanine: NONE
- Magnolia: NONE
- Epimedium: NONE
- Ashwagandha: NONE
Personally, I find Ashwagandha the most intriguing of all the listed ingredients, not least because Meghan said she sometimes takes additional doses of the herb. Why might that be? There is very little reliable research on this (or any of the other above-listed) remedy; but I found one placebo-controlled study which concluded that Ashwagandha “may improve sexual function in healthy women”.
Before my readers now rush out in droves to the next health food shop, I should issue a stern warning: the trial was flimsy and the results lack independent confirmation.
She also seems to have a weakness for homeopathy
On this blog, we have seen more than enough evidence of how some proponents of alternative medicine can react when they feel cornered by critics. They often direct vitriol in their direction. Ad hominem attacks are far from being rarities. A more forceful option is to sue them for libel. In my own case, Prince Charles went one decisive step further and made sure that my entire department was closed down. In China, they have recently and dramatically gone even further.
This article in Nature tells the full story:
A Chinese doctor who was arrested after he criticized a best-selling traditional Chinese remedy has been released, after more than three months in detention. Tan Qindong had been held at the Liangcheng county detention centre since January, when police said a post Tan had made on social media damaged the reputation of the traditional medicine and the company that makes it.
On 17 April, a provincial court found the police evidence for the case insufficient. Tan, a former anaesthesiologist who has founded several biomedical companies, was released on bail on that day. Tan, who lives in Guangzhou in southern China, is now awaiting trial. Lawyers familiar with Chinese criminal law told Nature that police have a year to collect more evidence or the case will be dismissed. They say the trial is unlikely to go ahead…
The episode highlights the sensitivities over traditional Chinese medicines (TCMs) in China. Although most of these therapies have not been tested for efficacy in randomized clinical trials — and serious side effects have been reported in some1 — TCM has support from the highest levels of government. Criticism of remedies is often blocked on the Internet in China. Some lawyers and physicians worry that Tan’s arrest will make people even more hesitant to criticize traditional therapies…
Tan’s post about a medicine called Hongmao liquor was published on the Chinese social-media app Meipian on 19 December…Three days later, the liquor’s maker, Hongmao Pharmaceuticals in Liangcheng county of Inner Mongolia autonomous region, told local police that Tan had defamed the company. Liangcheng police hired an accountant who estimated that the damage to the company’s reputation was 1.4 million Chinese yuan (US$220,000), according to official state media, the Beijing Youth Daily. In January, Liangcheng police travelled to Guangzhou to arrest Tan and escort him back to Liangcheng, according to a police statement.
Sales of Hongmao liquor reached 1.63 billion yuan in 2016, making it the second best-selling TCM in China that year. It was approved to be sold by licensed TCM shops and physicians in 1992 and approved for sale over the counter in 2003. Hongmao Pharmaceuticals says that the liquor can treat dozens of different disorders, including problems with the spleen, stomach and kidney, as well as backaches…
Hongmao Pharmaceuticals did not respond to Nature’s request for an interview. However, Wang Shengwang, general manager of the production center of Hongmao Liquor, and Han Jun, assistant to the general manager, gave an interview to The Paper on 16 April. The pair said the company did not need not publicize clinical trial data because Hongmao liquor is a “protected TCM composition”. Wang denied allegations in Chinese media that the company pressured the police to pursue Tan or that it dispatched staff to accompany the police…
Xia is worried that the case could further silence public criticism of TCMs, environmental degredation, and other fields where comment from experts is crucial. The Tan arrest “could cause fear among scientists” and dissuade them from posting scientific comments, he says.
END OF QUOTE
On this blog, we have repeatedly discussed concerns over the validity of TCM data/material that comes out of China (see for instance here, here and here). This chilling case, I am afraid, is not prone to increase our confidence.
Most diabetics need life-long medication. Understandably, this makes many fed-up, and some think that perhaps natural remedies might be a less harmful, less intrusive way to control their condition. They don’t have to look far to find an impressively large choice.
This article in the Canadian Journal of Diabetes was aimed at reviewing CAM, including natural health products (NHP) and others, such as yoga, acupuncture, tai chi and reflexology, that have been studied for the prevention and treatment of diabetes and its complications. It claims that, in adults with type 2 diabetes, the following NHP have been shown to lower glycated hemoglobin (A1C) by at least 0.5% in randomized controlled trials lasting at least 3 months:
Ayurveda polyherbal formulation
Ginger (Zingiber officinale)
Lichen genus Cladonia BAFS “Yagel-Detox”
Marine collagen peptides
Nettle (Urtica dioica)
Oral aloe vera
Pterocarpus marsupium (vijayasar)
Scoparia dulcis porridge
Soybean-derived pinitol extract
Touchi soybean extract
Traditional Chinese medicine herbs:
Gegen Qinlian Decoction (GQD)
Jianyutangkang (JYTK) with metformin
Jinlida with metformin
Shen-Qi-Formula (SQF) with insulin
Xiaoke (contains glyburide)
Trigonella foenum-graecum (fenugreek)
Even though the authors caution that these remedies should not be recommended for routine use, I fear that such lists do motivate diabetics to give them a try. If they do, the outcome could be that:
- Nothing at all happens other than the patient wasting some money on useless remedies. The clinical trials on which the above list is based are usually so flimsy that their findings are next to meaningless and quite possibly false-positive.
- The patient might, if the remedy does affect blood sugar levels, develop hypoglycaemia. If severe, this could be life-threatening.
- The patient might trust in a natural remedy and thus discontinue the prescribed anti-diabetic medication. In this case, she could develop hyperglycaemia. If severe, this could be life-threatening.
It seems obvious that none of the possible outcomes are in the patients’ interest. I fear that it is dangerous to tempt diabetics with the possibility that a natural remedy. Even if such treatments did work, they are not well-researched, unreliable and do not have sufficiently large effects (a 0.5% decrease of glycated haemoglobin is hardly impressive) to represent realistic options.
An article in yesterday’ Times makes the surprising claim that ‘doctors turn to herbal cures when the drugs don’t work’. As the subject is undoubtedly relevant to this blog and as the Times is a highly respected newspaper, I think this might be important and will therefore comment (in normal print) on the full text of the article (in bold print):
GPs are increasingly dissatisfied with doling out pills that do not work for illnesses with social and emotional roots, and a surprising number of them end up turning to alternative medicine.
What a sentence! I would have thought that GPs have always been ‘dissatisfied’ with treatments that are ineffective. But who says they turn to alternative medicine in ‘surprising numbers’ (our own survey does not confirm the notion)? And what is a ‘surprising number’ anyway (zero would be surprising, in my view)?
Charlotte Mendes da Costa is unusual in being both an NHS GP and a registered homeopath. Her frustration with the conventional approach of matching a medicine to a symptom is growing as doctors increasingly see the limits, and the risks, of such a tactic.
Do we get the impression that THE TIMES does not know that homeopathy is not herbal medicine? Do they know that ‘matching a medicine to a symptom’ is what homeopaths believe they are doing? Real doctors try to find the cause of a symptom and, whenever possible, treat it.
She asks patients with sore throats questions that few other GPs pose: “What side is it? Is it easier to swallow solids or liquids? What time of day is it worst?” Dr Mendes da Costa is trying to find out which homeopathic remedy to prescribe. But when NHS guidance for sore throats aims mainly to convince patients that they will get better on their own, her questions are just as important as her prescription.
This section makes no sense. Sore throats do get better on their own, that’s a fact. And empathy is not a monopoly of homeopaths. But Dr Mendes Da Costa might be somewhat detached from reality; she once promoted the nonsensical notion that “up to the end of 2010, 156 randomised controlled trials (RCTs) in homeopathy had been carried out with 41% reporting positive effects, whereas only 7% have been negative. The remainder were non-conclusive.” (see more on this particular issue here)
“It’s very difficult to disentangle the effect of listening to someone properly, in a non-judgmental way, and taking a real rather than a superficial interest,” she says. “With a sore throat [I was trained] really only to be interested in, ‘Do they need antibiotics or not?’ ”
In this case, she should ask her money back; her medical school seems to have been rubbish in training her adequately.
This week a Lancet series on back pain said that millions of patients were getting treatments that did them no good. A government review is looking into how one in 11 people has come to be on potentially addictive drugs such as tranquillisers, opioid painkillers and antidepressants.
Yes, and how is that an argument for homeopathy? It isn’t! It seems to come from the textbook of fallacies.
And this week a BMJ Open study found that GPs with alternative training prescribed a fifth fewer antibiotics.
That study was akin to showing that butchers sell less vegetables than green-grocers. It provided no argument at all for implying that homeopathy is a valuable therapy.
Doctors seem receptive to alternative approaches: in a poll on its website 70 per cent agreed that doctors should recommend acupuncture to patients in pain. The Faculty of Homeopathy now counts 400 doctors among its 700 healthcare professional members.
Wow! Does the Times journalist know that the ‘Faculty of Homeopathy’ is primarily an organisation for doctor homeopaths? If so, why are these figures anything to write home about? And does the author appreciate that the pole was open not just to doctors but to to anyone (particularly those who were motivated, like acupuncturists)?
This horrifies many academics, who say that there is almost no evidence that complementary therapies work.
It horrifies nobody, I’d say. It puzzles some people, and not just academics. And their claim of a lack of sound evidence is evidence-based.
“It’s a false battle”, says Michael Dixon, a GP who chairs the College of Medicine, which is trying to broaden the focus on treatment to patients’ whole lives. “GPs are practical. If a patient gets better that’s all that matters.”
Dr Dixon says there are enormous areas of illness ranging from chronic pain to irritable bowels where few conventional treatments have been shown to be particularly effective, so why not try alternatives with fewer side effects?
Unable to diagnose and treat adequately, let’s all do the next worst thing and apply some outright quackery?!? Logic does not seem to be Dixon’s strong point, does it?
He recommends herbal remedies such as pelargonium — “like a geranium, quite a pretty little flower” — acupressure, and techniques such as self-hypnosis. To those who say these are placebos he replies: so what?
So what indeed! There are over 200 species of pelargonium; only 2 or 3 of them are used in herbal medicine. I don’t suppose Dr Dixon wants to poison us?
“Aromatherapy does work, but only if you believe in it, that’s the way you have to look at it, like a mother kissing knees better.” He continues: “We are healers. That’s what we do as doctors. You can call it theatrical or you can call it a relationship. A lot of patients come in with a metaphor — a headache is actually unhappiness — and the treatment is symbolic.”
It frightens me to know that there are doctors out there who think like this!
What if a patient is seriously ill?
A cancer is a metaphor for what exactly?
As doctors, we have the ethical duty to apply BOTH the science and the art of medicine, BOTH efficacious, evidence-based therapies AND compassion. Can I be so bold as to recommend our book about the ethics of alternative medicine to Dixon?
Such talk makes conventional doctors very nervous. Yet acupuncture illustrates their dilemma. It used to be recommended by the NHS for back pain because patients did improve. Now it is not, after further evidence suggested that patients given placebo “sham acupuncture” did just as well.
No, acupuncture used to be recommended by NICE because there was some evidence; when subsequently more rigorous trials emerged showing that it does NOT work, NICE stopped recommending it. Real medicine develops – it’s only alternative medicine and its proponents that seem to be stuck in the past and resist progress.
Martin Underwood, of the University of Warwick, asks: “So are you going to say, ‘Well, patients get better than they would do otherwise’? Or say it’s all theatrical placebo because it shows no benefit over sham treatment? That’s the question for society.”
Society has long answered it! The answer is called evidence-based medicine. We are not content using quackery for its placebo response; we know that effective treatments do that too, and we want to make progress and improve healthcare of tomorrow.
Although many doctors agree that they need to look at patients more broadly, they insist they do not need to turn to unproven treatments. The magic ingredient, they say, is not an alternative remedy, but time. Helen Stokes-Lampard, chairwoman of the Royal College of GPs, said: “Practices which offer alternative therapies tend to spend longer with patients . . . allowing for more in-depth conversations.”
I am sorry, if this post turned into a bit of a lengthy rant. But it was needed, I think: if there ever was a poorly written, ill focussed, badly researched and badly argued article on alternative medicine, it must be this one.
Did I call the Times a highly respected paper?
I take it back.
At least this is what the authors of this new study want us to believe.
But are they right?
This RCT is entitled ‘Efficacy and tolerability of a complex homeopathic drug in children suffering from dry cough-A double-blind, placebo- controlled, clinical trial’. It recruited children suffering from acute dry cough to assess the efficacy and tolerability of a complex homeopathic remedy in liquid form (Drosera, Coccus cacti, Cuprum Sulfuricum, Ipecacuanha = Monapax syrup, short: verum).
The authors stated that “preparations of Drosera, Coccus cacti, Cuprum sulfuricum, and Ipecacuanha are well-known antitussives in homeopathic medicine. Each of them is connected with special subtypes of cough. Drosera is intended for inflammations of the respiratory tract, especially for whooping cough. Coccus cacti is intended for inflammations of the nasopharyngeal space and the respiratory tract. Cuprum sulfuricum is intended for spasmodic coughing at night. Ipecacuanha is intended for bronchitis, bronchial asthma, and whooping cough. The complex homeopathic drug explored in this trial consists of all four of these active substances.”
According to the authors of the paper, “the primary objective of the trial was to demonstrate the superiority of verum compared to the placebo”.
A total of 89 children, enrolled in the Ukraine between 15/04/2008 and 26/05/2008 in 9 trial centres, received verum and 91 received placebo daily for 7 days (age groups 0.5–3, 4–7 and 8–12 years). The trial was conducted using an adaptive 3-stage group sequential design with possible sample size adjustments after the two planned interim analyses. The inverse normal method of combining the p-values from all three stages was used for confirmatory hypothesis testing at the interim analyses as well as at the final analysis. The primary efficacy variable was the improvement of the Cough Assessment Score. Tolerability and compliance were also assessed. A confirmatory statistical analysis was performed for the primary efficacy variable and a descriptive analysis for the secondary parameters.
A total of 180 patients (89 in the verum and 91 in the placebo group) evaluable according to the intention-to-treat principle were included in the trial. The Cough Assessment Score showed an improvement of 5.2 ± 2.6 points for children treated with verum and 3.2 ± 2.6 points in the placebo group (p < 0.0001). The difference of the least square means of the improvements was 1.9 ± 0.4. The effect size of Cohen´s d was d = 0.77. In all secondary parameters the patients in the verum group showed higher rates of improvement and remission than those in the placebo group. In 15 patients (verum: n = 6; placebo: n = 9) 18 adverse drug reactions of mild or moderate intensity were observed.
The authors concluded that the administering verum resulted in a statistically significantly greater improvement of the Cough Assessment Score than the placebo. The tolerability was good and not inferior to that of the placebo.
This study seems fairly rigorous. What is more, it has been published in a mainstream journal of reasonably high standing. So, how can its results be positive? We all know that homeopathy does not work, don’t we?
Are we perhaps mistaken?
Are highly diluted homeopathic remedies effective after all?
I don’t think so.
Let me explain to you a few points that raise my suspicions about this study:
- It was conducted 10 years ago; why did it take that long to get it published?
- I don’t think highly of a study with “the primary objective … to demonstrate the superiority” of the experimental interventions. Scientists use RCTs for testing efficacy and pseudo-scientist use it for demonstrating it, I think.
- The study was conducted in the Ukraine in 9 centres, yet no Ukrainian is an author of the paper, and there is not even an acknowledgement of these primary investigators.
- The ‘adaptive 3-stage group sequential design with possible sample size adjustments’ sounds very odd to me, but I may be wrong; I am not a statistician.
- We learn that 180 patients were evaluated, but not how many were entered into the trial?
- The Cough Assessment Score is not a validated outcome measure.
- Was the verum distinguishable from the placebo? It would be easy to test whether the patients/parents were truly blinded. Yet no such results were included.
- The trial was funded by the manufacturer of the homeopathic remedy.
- The paper has three authors 1)Hans W. Voß has no conflict of interest to declare. 2) Rainer Brünjes is employed at Cassella-med, the marketing authorisation holder of the study product. 3) Andreas Michalsen has consulted for Cassella-med and participated in advisory boards.
I know, homeopathy fans will think I am nit-picking; and perhaps they are correct. So, let me tell you why I really do strongly reject the notion that this study shows or even suggests that highly diluted homeopathic remedies are more than placebos.
The remedy used in this study is composed of Drosera 0,02 g, Hedera helix Ø 0,04 g, China D1 0,02 g, Coccus cacti D1 0,04 g, Cuprum sulfuricum D4 2,0 g, Ipecacuanha D4 2,0 g, Hyoscyamus D4 2,0 g.
In case you don’t know what ‘Ø’ stands for (I don’t blame you, hardly anyone outside the world of homeopathy does), it signifies a ‘mother tincture’, i. e. an undiluted herbal extract; and ‘D1’ signifies diluted 1:10. This means that the remedy may be homeopathic from a regulatory point of view, but for all intents and purposes it is a herbal medicine. It contains an uncounted amount of active compounds, and it is therefore hardly surprising that it might have pharmacological effects. In turn, this means that this trial does by no means overturn the fact that highly diluted homeopathic remedies are pure placebos.
It’s a pity, I find, that the authors of the paper fail to explain this simple fact in full detail – might one think that they intentionally aimed at misleading us?
“In my medical practice, writes Sheila Patel, M.D. on the website of Deepak Chopra, I always take into consideration the underlying dosha of a patient, or what their main imbalance is, when choosing treatments out of the many options available. For example, if I see someone who has the symptoms of hypertension as well as a Kapha imbalance, I may prescribe a diuretic, since excess water is more likely to be a contributing factor. I would also encourage more exercise or physical activity, since lack of movement is often a causative factor for these individuals. However, in a Vata-type person with hypertension, a diuretic may actually cause harm, as the Vata system tends to have too much dryness (air and space). I’ve observed that Vatas often have more side effects and electrolyte imbalances due to the diuretic medication. For these individuals, a beta-blocker may be a better choice, as this “slows” down the excitatory pathways in the body. In addition, I recommend meditation and calming activities to settle the excess energy as an adjunct to (or at times, instead of) the medicine. Alternatively, for someone with hypertension who is predominantly a Pitta type or who has a Pitta imbalance, I may choose a calcium-channel blocker, as this medication may be more beneficial in regulating the process of “energy exchange” in the body, which is represented by the fire element of Pitta. This is just one example of the way in which we can tailor our choice of medication to best suit the individual.
“In contrast with conventional medicine, which until very recently has assumed that a given disorder or disease is the same in all people, Ayurveda places great importance on recognizing the unique qualities of individual human beings. Ayurveda’s understanding of constitutional types or doshas offers us a remarkably accurate way to pinpoint what is happening inside each individual, allowing us to customize treatment and offer specific lifestyle recommendations to prevent disease and promote health and longevity. Keeping the doshas balanced is one of the most important factors in keeping the whole mind-body system in balance. When our mind-body system is in balance and we are connecting to our inner wisdom and intelligence, then we are most able to realize our full human potential and achieve our optimal state of being…”
END OF QUOTE
From such texts, some might conclude that Ayurvedic medicine is gentle and kind (personally, I am much more inclined to feel that Ayurvedic medicine is full of BS). This may be true or not, but Ayurvedic medicines are certainly anything but gentle and kind. In fact, they can be positively dangerous. I have repeatedly blogged about their risks, in particular the risk of heavy metal poisoning (see here, here, and here, for instance).
My 2002 systematic review summarised the evidence available at the time and concluded that heavy metals, particularly lead, have been a regular constituent of traditional Indian remedies. This has repeatedly caused serious harm to patients taking such remedies. The incidence of heavy metal contamination is not known, but one study shows that 64% of samples collected in India contained significant amounts of lead (64% mercury, 41% arsenic and 9% cadmium). These findings should alert us to the possibility of heavy metal content in traditional Indian remedies and motivate us to consider means of protecting consumers from such risks.
Meanwhile, new data have emerged and a new article with important information has recently been published by authors from the Department of Occupational and Environmental Health , College of Public Health, The University of Iowa and the State Hygienic Laboratory at the University of Iowa, USA. They present an analysis based on reports of toxic metals content of Ayurvedic products obtained during an investigation of lead poisoning among users of Ayurvedic medicine. Samples of Ayurvedic formulations were analysed for metals and metalloids following established US. Environmental Protection Agency methods. Lead was found in 65% of 252 Ayurvedic medicine samples with mercury and arsenic found in 38 and 32% of samples, respectively. Almost half of samples containing mercury, 36% of samples containing lead, and 39% of samples containing arsenic had concentrations of those metals per pill that exceeded, up to several thousand times, the recommended daily intake values for pharmaceutical impurities.
The authors concluded that lack of regulations regarding manufacturing and content or purity of Ayurvedic and other herbal formulations poses a significant global public health problem.
I could not have said it better myself!
