My ‘Corona-Virus Quackery Club’ (CVQC) is getting rather popular. The current members,
are now thinking of admitting the essential oil salesmen. It seems that many of them find it impossible to resist the chance to make a fast buck on the fear many consumers currently have. Take this website for instance:
If you have a breathing aid or respiratory device, use it to reduce breathing difficulties. Alternatively, you can use a breathing ointment like Breathe and Focus Oil. Formulated with menthol, eucalyptus, rosemary and thyme essential oils, this phyto-aromatherapy ointment helps ease breathing difficulties commonly associated with cold, flu, cough, asthma and pneumonia. Gently massage a few drops of Breathe and Focus Oil to your chest and apply 1 to 2 drops to a tissue or handkerchief then inhale the aroma. Repeat as often as necessary.
Studies showed that eucalyptus essential oil contains cineole that helps reduce inflammation and infection in the lungs. Eucalyptus Radiata essential oil has antiviral effects against coronavirus SARS. Rosemary essential oil has been shown to be effective against Klebsiella pneumoniae, a bacteria which causes pneumonia in humans and animals. Thyme essential oil has been shown to have antiviral activities against Influenza A virus (H1N1), while menthol with its cooling-effect has also been shown to reduce breathing difficulties. These essential oils may help you dealing with Covid-19 disease.
Another website even has the promising title ‘What can you try to cure from coronavirus ….’ and it tells us that:
Black cumin can boost immunity, especially in patients with impaired immune systems. According to research, 1 gram Seed capsules, twice daily for four weeks can improve T-cell ratio between positive and negative up to 72%. Increased immunity plays an important role in the healing of colds, influenza, AIDS, and other diseases related to the immune system.
But there is more – so much more that I can here only present a very small selection of that is on offer.
- Cinnamon bark
- Clove bud
- Eucalyptus globulus/radiata
- Lemon myrtle
- Tea tree
- Thyme thymol & linalool
Yet another website includes the claim: “The most powerful anti-virus essential oils to provide defence (sic) against coronavirus include:
- Cedarwood Virginian
- Clove Bud
- Eucalyptus Globulus, Radiata and Smithii
- Juniper Berry
- Lavender Spike
- Laurel leaf
- Tea Tree
- Thyme Sweet Thyme White.”
I know, this is confusing! I do sympathise with the difficulty of choosing between all these recommendation; therefore, let me help you. Here is the full list of essential oils proven to prevent or treat a corona-virus infection:
Yes, that’s right: NO ESSENTIAL OIL HAS EVER BEEN FOUND TO BE EFFECTIVE AGAINST THIS OR ANY OTHER VIRUS INFECTION!
The FDA agree and have therefore sent out letters to seven US companies warning them to stop selling products that claim to cure or prevent COVID-19 infections, stating that such products are a threat to public health because they might prompt consumers to stop or delay appropriate medical treatment.
WELCOME TO THE CVQC, ESSENTIAL OIL SALESMEN!
It has been reported that Brazil and India will collaborate in the promotion of quackery! Brazil’s president Jair Bolsonaro and India’s Prime Minister Narendra Modi, have just signed several agreements on collaboration. Agreement 8 is particularly intriguing:
8. Memo of agreement for cooperation in Traditional Medicine and Homeopathy
We seek to promote and develop bilateral cooperation in the field of traditional medicine and homeopathy. The areas of cooperation provided for in the instrument include exchange of experience in teaching regulations, practices, medicines and non-medicine therapies; knowledge promotion, exchange of training for therapists, health professionals, scientists, teaching professionals and students; and development of joint research, besides educational and training programs.
Homeopathy, already a recognized medical specialty in Brazil, is currently offered for free by the Brazilian national healthcare system. Other so-called alternative medicines (SCAMs) employed in the Brazilian healthcare system include:
- spiritual healing,
- crystal healing,
Homeopathy and acupuncture are also recognized by the Brazilian Federal Council and both are taught in the most prestigious public Universities, in medical, veterinary, public health and nursing schools.
India has gone one step further by establishing its AYUSH ministry. It registers SCAM practitioners considered ‘indigenous’ by the Indian government under a separate board. The SCAMs thus regulated are:
- Yoga and Naturopathy,
- Unani and Tibbi,
In India, practitioners are taught some of these subjects as MBBS ( Bachelor of Medicine and Surgery). The graduates are then considered to be ‘doctors’. In Brazil, homeopathy and acupuncture are practiced by medical doctors. Brazilian citizens are thus misled to believe that these SCAMs are evidence-based.
So, what this ‘bilateral co-operation’ is going to achieve? Narendra Nayak (President of the Federation of Indian Rationalist Associations and former Assistant Professor of Biochemistry in Mangalore) and Natalia Pasternak (President of the Instituto Questão de Ciência in São Paulo) are less than optimistic:
Exchange of ‘technology’ of so called ‘psychic surgery’ of quacks like the late José Arigo, “the surgeon with the rusty knife”, with specialists of gaumutra (urine of India’s allegedly indigenous cows) whose concoction is supposed to be a panacea for 440 diseases? Is Brazil going to export to India the peculiar surgical techniques of the “medium” John of God, recently arrested, not for years of practicing unlicensed medicine and hurting people, but for sexual harassment and rape? Don’t get the wrong message, we are very glad John of God was convicted, and very glad for the brave women who came forward, but we cannot ignore the fact that he was never bothered by the authorities for placing people under his (usually not quite clean) knife.
Since India and Brazil are leaders in sugar production, are they going to support Homeopathy? Also the use of alcohol to produce their tinctures?
Again, we wonder why India and Brazil are going for an alleged system of medicine called homeopathy which is nowhere in the mainstream in the country of its origin -Germany. And why do they embrace it while the rest of the world is pushing back against homeopathy, after several scientific papers, reviews and meta-analyses showed beyond any reasonable doubt that it doesn’t work?
Brazil and India have much in common, both are rising developing economies, with a diverse population, trying to be true to their democratic ideals. Unfortunately, another similarity comes to light: the fact that presently both our countries are governed by rulers that have shown total disregard by scientific knowledge and evidence in many of their public policy decisions.
As heads of organizations that promote science and rational thinking in Brazil and India, we regret the decision of our governments to promote quackery as a legitimate subject of an international agreement.
I feel that individuals and organisations promoting critical thinking in other parts of the world should lend their support to these two courageous people.

They recently conducted independent lab tests on the purity of 33 samples of essential ois from well-known names in the essential oil industry to see what was really inside each bottle. Their report raises lots of concerns, in my view. The team that wrote the report kindly sent me a summary and asked me to publish it here which I now do without any alteration, abbreviation or further comment:
Everybody’s talking about essential oils. More importantly, everybody’s using them. The global demand for these fragrant chemical compounds reached an extraordinary 226.9 kilotons in 2018 and further growth is projected by the marketing people who measure such things. The proliferation of essential oil users is tied to growth in the food and beverage, personal care and aromatherapy industries.
It’s not surprising that the scientific study of essential oils has also increased with demand for the products. The best essential oil brands invest in quality testing but don’t necessarily follow scientific protocol or make detailed testing results available to consumers. So the literature is still limited— and the jury is still out on whether these compounds are effective in treating medical conditions.
Essential oils are extracted from plants. In their pure form, they are highly concentrated—and sometimes toxic. To make them practical to use, essential oils are typically mixed with diluting carrier oils. Methods of extraction include cold-pressing, steam and water distillation, and the use of chemical solvents. Evaluating individual products made with essential oils is challenging because there are thousands of brands on the market. Neither the extraction methods used or the potency of the products—let alone, testing methods—are standardized. Manufacturers’ ambitious marketing claims, which often rely on ambiguous language, further obscure consumers’ ability to judge for themselves which oils are best suited to their purposes. The list of problems some products purport to solve can run the gamut from an itchy scalp to menopause symptoms.
What’s more, few essential oil manufacturers educate consumers on proper dosage or contraindications, which can lead to accidental misuse and illness. Children are particularly sensitive to many oils and yet most manufacturers fail to warn against applying oils to children’s skin. Pregnant women are usually advised not to use essential oils during their first trimesters, though some studies have suggested they can help alleviate pain during childbirth. Some essential oils should never be used during pregnancy. Essential oils can interact or interfere with prescription medicines and nutritional supplements. But unlike prescription drugs, they don’t come with warning labels about these potential interactions.
Genuinely scientific, peer-reviewed studies of essential oils have primarily focused on using aromatherapy as an adjunct to conventional medical treatment. Science has confirmed that when inhaled, essential oil molecules travel quickly to the brain—specifically the limbic region, which controls pulse, respiration, sexual arousal, and other autonomic functions. Emotional responses like fear and motivation originate in the limbic system. The most promising applications of aromatherapy appear to be in diminishing stress and offering pain relief. But actual clinical trials into such topics as reducing nausea in by chemotherapy patients, relieving anxiety during childbirth, alleviating headaches, and improving sleep have been inconclusive.
Other studies have focused on the subject of inflammation, which is known to contribute to a wide range of medical problems. Essential oils derived from the thyme, clove, rose, eucalyptus, fennel, and bergamot have been demonstrated through one study to activate chemicals in the body which suppress inflammation and suppress chemicals that activate it.
Researchers are also exploring the potential of essential oils as antibacterial agents. Parts of the juniper, cumin, coriander and lavender plants may be effective in battling E coli, while cinnamon may prove useful in treating strep throat and pneumonia.
As ancient and traditional as their use may be in certain cultures, the scientific reality is it’s too early to tell how effective essential oils are in treating the wide range of conditions they are theorized (and now, commonly advertised) to treat.
But that’s not to say you shouldn’t use them, according to recommendations from your doctor. When considering the efficacy of essential oils, bear in mind that the act of self-care can be therapeutic in and of itself. We all know that treating ourselves to a hot bath—or an ice cream cone for that matter—can give us a temporary sense of well-being. For the time being, short-term selfsoothing may be all we can count on from essential oils. But there’s something to be said for even temporary relief. An entire industry of over-the-counter medicines has been founded upon it.
According to the 2014 European Social Survey, Spain is relatively modest when it comes to using alternative therapies. While countries such as Austria, Denmark, Estonia, Finland, France, Germany, Lithuania, Sweden and Switzerland all have 1-year prevalence figures of over 30%, Spain only boasts a meagre 17%. Yet, its opposition to bogus treatments has recently become acute.
In 2016, it was reported that a master’s degree in homeopathic medicine at one of Spain’s top universities has been scrapped. Remarkably, the reason was “lack of scientific basis”. A university spokesman confirmed the course was being discontinued and gave three main reasons: “Firstly, the university’s Faculty of Medicine recommended scrapping the master’s because of the doubt that exists in the scientific community. Secondly, a lot of people within the university – professors and students across different faculties – had shown their opposition to the course. Thirdly, the postgraduate degree in homeopathic medicine is no longer approved by Spain’s Health Ministry.”
A few weeks ago, I had the great pleasure of being invited to a science festival in Bilbao and was impressed by the buoyant sceptic movement in Spain. At the time, two of my books were published in Spanish and received keen interest by the Spanish press.
And now, it has been reported that Spain’s Ministry of Health has released a list of only 2,008 homeopathic products whose manufacturers will have to apply for an official government license for if they wish to continue selling them. The homeopathic producers have until April 2019 to prove that their remedies actually work, which may very well completely slash homeopathic products in Spain.
It’s the latest blow for Spain’s homeopathy industry, once worth an estimated €100 million but which has seen a drop in public trust and therefore sales of around 30 percent in the last five years. Spain’s Health Ministry stopped allowing homeopathy treatments from being prescribed as part of people’s social security benefits, along with acupuncture, herbal medicine and body-based practices such as osteopathy, shiatsu or aromatherapy.
“Homeopathy is an alternative therapy that has not shown any scientific evidence that it works” Spanish Minister of Health Maria Luisa Carcedo is quoted as saying in La Vanguardia in response to the homeopathic blacklist. “I’m committed to combatting all forms of pseudoscience.”
After a previous post about aromatherapy, someone recently commented:
I love essential oils and use them daily. Essential oils became a part of my life! I do feel better with it! Why I need clinical trials so?
The answer is probably: you don’t need clinical trials for a little pampering that makes you feel good.
But, if someone claims that aromatherapy (or indeed any other treatment) is effective for this or that medical condition, we need proof in the form of a clinical trial. By proof, we usually mean a clinical trial.
One like this new study, perhaps?
The aim of this study was to evaluate the use of a lavender aromatherapy skin patch on anxiety and vital sign variability during the preoperative period in female patients scheduled for breast surgery. Participants received an aromatherapy patch in addition to standard preoperative care. Anxiety levels were assessed with a 10-cm visual analogue scale (VAS) at baseline and then every 15 minutes after patch placement. Vital sign measurements were recorded at the same interval. There was a statistically significant decrease (P = .03) in the anxiety VAS measurements from baseline to final scores.
The authors concluded that the findings from this study suggest the use of aromatherapy is beneficial in reducing anxiety experienced by females undergoing breast surgery. Further research is needed to address the experience of preoperative anxiety, aromatherapy use, and the challenges of managing preoperative anxiety.
No, not one like this study!
This study – its called it a ‘pilot study’ – tells us nothing of value.
- It was not a pilot study because it did not pilot anything; its aim was to evaluate aromatherapy.
- But it could not evaluate aromatherapy because it had no control group. This means the reduction in anxiety was almost certainly not a specific effect of the therapy, but a non-specific effect due to the extra attention, expectation, etc.
- This means that the conclusion (the use of aromatherapy is beneficial) is not justified.
- In turn, this means that the paper is not helpful in any way. All it can possibly do is to mislead the public.
In summary: another fine example of pseudo-research that, I believe, is worse than no research at all.
Aromatherapy usually involves the application of diluted essential (volatile) oils via a gentle massage of the body surface. The chemist Rene-Maurice Gattefosse (1881-1950) coined the term ‘aromatherapy’ after experiencing that lavender oil helped to cure a severe burn of his hand. In 1937, he published a book on the subject: Aromathérapie: Les Huiles Essentielles, Hormones Végétales. Later, the French surgeon Jean Valnet used essential oils to help heal soldiers’ wounds in World War II.
Aromatherapy is currently one of the most popular of all alternative therapies. The reason for its popularity seems simple: it is an agreeable, luxurious form of pampering. Whether it truly merits to be called a therapy is debatable.
The authors of this systematic review stated that they wanted to critically assess the effect of aromatherapy on the psychological symptoms as noted in the postmenopausal and elderly women. They conducted electronic literature searches and fount 4 trials that met their inclusion criteria. The findings demonstrated that aromatherapy massage significantly improves psychological symptoms in menopausal, elderly women as compared to controls. In one trial, aromatherapy massage was no more effective than the untreated group regarding their experience of symptoms such as nervousness.
The authors concluded that aromatherapy may be beneficial in attenuating the psychological symptoms that these women may experience, such as anxiety and depression, but it is not considered as an effective treatment to manage nervousness symptom among menopausal women. This finding should be observed in light of study limitations.
In the discussion section, the authors state that to the best of our knowledge, this is the first meta-analysis evaluating the effect of aromatherapy on the psychological symptoms. I believe that they might be mistaken. Here are two of my own papers (other researchers have published further reviews) on the subject:
- Aromatherapy is the therapeutic use of essential oil from herbs, flowers, and other plants. The aim of this overview was to provide an overview of systematic reviews evaluating the effectiveness of aromatherapy. We searched 12 electronic databases and our departmental files without restrictions of time or language. The methodological quality of all systematic reviews was evaluated independently by two authors. Of 201 potentially relevant publications, 10 met our inclusion criteria. Most of the systematic reviews were of poor methodological quality. The clinical subject areas were hypertension, depression, anxiety, pain relief, and dementia. For none of the conditions was the evidence convincing. Several SRs of aromatherapy have recently been published. Due to a number of caveats, the evidence is not sufficiently convincing that aromatherapy is an effective therapy for any condition.
- Aromatherapy is becoming increasingly popular; however there are few clear indications for its use. To systematically review the literature on aromatherapy in order to discover whether any clinical indication may be recommended for its use, computerised literature searches were performed to retrieve all randomised controlled trials of aromatherapy from the following databases: MEDLINE, EMBASE, British Nursing Index, CISCOM, and AMED. The methodological quality of the trials was assessed using the Jadad score. All trials were evaluated independently by both authors and data were extracted in a pre-defined, standardised fashion. Twelve trials were located: six of them had no independent replication; six related to the relaxing effects of aromatherapy combined with massage. These studies suggest that aromatherapy massage has a mild, transient anxiolytic effect. Based on a critical assessment of the six studies relating to relaxation, the effects of aromatherapy are probably not strong enough for it to be considered for the treatment of anxiety. The hypothesis that it is effective for any other indication is not supported by the findings of rigorous clinical trials.
Omitting previous research may be odd, but it is not a fatal flaw. What makes this review truly dismal is the fact that the authors fail to discuss the poor quality of the primary studies. They are of such deplorable rigor that one can really not draw any conclusion at all from them. I therefore find the conclusions of this new paper unacceptable and think that our statement (even though a few years old) is much more accurate: the evidence is not sufficiently convincing that aromatherapy is an effective therapy for any condition.
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.
Detox: no good evidence to show stimulation of self-healing powers.
Energy healing: no good evidence to show stimulation of self-healing powers.
Feldenkrais: no good evidence to show stimulation of self-healing powers.
Gua sha: no good evidence to show stimulation of self-healing powers.
Herbal medicine: no good evidence to show stimulation of self-healing powers.
Homeopathy: no good evidence to show stimulation of self-healing powers.
Macrobiotics: no good evidence to show stimulation of self-healing powers.
Naturopathy: no good evidence to show stimulation of self-healing powers.
Osteopathy: no good evidence to show stimulation of self-healing powers.
Power bands: no good evidence to show stimulation of self-healing powers.
Reiki: no good evidence to show stimulation of self-healing powers.
Reflexology: no good evidence to show stimulation of self-healing powers.
Shiatsu: no good evidence to show stimulation of self-healing powers.
Tai chi: no good evidence to show stimulation of self-healing powers.
TCM: 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.
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 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.
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.
This randomized controlled trial was aimed to investigate the effect of aromatherapy massage on anxiety, depression, and physiologic parameters in older patients with acute coronary syndrome. It was conducted on 90 older women with acute coronary syndrome. The participants were randomly assigned into the intervention and control groups. The intervention group received reflexology with lavender essential oil plus routine care and the control group only received routine care. Physiologic parameters, the levels of anxiety and depression in the hospital were evaluated using a checklist and the Hospital’s Anxiety and Depression Scale, respectively, before and immediately after the intervention.
Significant differences in the levels of anxiety and depression were reported between the groups after the intervention. The analysis of physiological parameters revealed a statistically significant reduction in systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate. However, no significant difference was observed in the respiratory rate.
The authors concluded that aromatherapy massage can be considered by clinical nurses an efficient therapy for alleviating psychological and physiological responses among older women suffering from acute coronary syndrome.
This trial does not show remotely what the authors think. It demonstrates that A+B is always more than B. We have discussed this phenomenon so often that I hesitate to mention it again. Any study with the ‘A+B versus B’ design can only produce a positive result. The danger that this result is false-positive is so high that it is best to forget about such investigations altogether.
Ethics committees should not accept such protocols.
Researchers should stop running such studies.
Reviewers should not pass them for publication.
Editors should not publish such trials.
THEY MISLEAD ALL OF US AND GIVE CLINICAL RESEARCH A BAD NAME.
