The NHMRC report on homeopathy is the most thorough, independent and reliable investigation into the value of homeopathy ever. As its conclusions are devastatingly negative about the value of homeopathy, it is hardly surprising that homeopaths tried everything and anything to undermine it. This new article gives what I believe to be a fair account of the allegations and their validity:
START OF QUOTE
Since the NHMRC declared homeopathy to be ineffective in treating any health condition, a number of disputes have been made by major organisations in favour of homeopathy. Australia’s two peak industry organisations, Complementary Medicines Australia (CMA) and the AHA, both argue in their letters to the NHRMC that the position was prejudiced based on a draft position statement leaked in 2012 stating it is unethical for health practitioners to treat patients using homeopathy, for the reason that homeopathy (as a medicine or procedure) has been shown not to be efficacious [19,20]. Furthermore, both the CMA and AHA highlight serious concerns regarding the prelude to and instigation of the work of the NHMRC’s HWC as well as the conduct of the review itself to finalise their conclusion on the use of homeopathy. Several grave issues were raised in both letters with five common key flaws cited: (1) no explanation was provided as to why level 1 evidence including randomised control trials were excluded from the review; (2) the database search used was not broad enough to capture complementary medicine and homeopathic specific content, and excluded non-human and non-English studies; (3) no homeopathic expert was appointed in the NHMRC Review Panel; (4) prior to publication, the concerns raised over the methodology and selective use of data by research contractor(s) engaged for the HWC review were abandoned for unknown reasons; and (5) no justification was provided as to why only systematic reviews were used [19,20]. Other serious accusations made by the AHA in their response letter to the NHMRC involved the blatant bias of the NHMRC evident by: the leakage of their draft position statement in April 2011 and early release of the HWC Draft Review regarding homeopathy to the media; no discussion of prophylactic homeopathy i.e. preventative healthcare; and no reference to the cost-effectiveness, safety, and quality of homeopathic medicines .
Despite the NHMRC findings being strongly disputed, they are further supported by positions taken by a number of large and respected organisations. For example, in 2009, the World Health Organization (WHO) advised against the use of homeopathic medicines for various serious diseases following significant concerns being raised by major health authorities, pharmaceutical industries, and consumers regarding its safety and quality . They reported the clinical effects were compatible with placebo effects . Similarly, in Australia, the Australian Medical Association (AMA) further supports the NHMRC findings by stating in their position statement released in 2012 that there is limited efficacy evidence regarding most complementary medicines, thereby posing a risk to patient health . More recently, in May 2015, the Royal College of General Practitioners (RACGPs) strongly advocated in their position statement against general practitioners prescribing homeopathic medicines, and pharmacists against supporting or recommending it, given the lack of evidence regarding its efficacy . This is particularly pertinent to conventional vaccines given the recent case between the Australian Competition and Consumer Commission (ACCC) vs. Homeopathy Plus! Australia Pty Ltd. The Federal Court found Homeopathy Plus! Australia Pty Ltd guilty of contravening the Australian Consumer Law by engaging in misleading and deceptive conduct through claiming that homeopathic remedies were a proven, safe, and effective alternative to the conventional vaccine against whooping cough .
The positions of the NHMRC, WHO, AMA, and the RACGPs regarding homeopathy is further supported by Cochrane reviews, which provide high-quality evidence with minimal bias . Of the twelve homeopathy Cochrane reviews available in the database, only seven address homeopathic remedies directly and were related to the following conditions: irritable bowel syndrome , attention deficit/hyperactivity disorder or hyperkinetic disorder , chronic asthma , dementia , induction of labour , cancer , and influenza . Given most of these reviews were authored by homeopaths, bias against homeopathy is unlikely [26-32]. The overarching conclusions from these reviews fail to reveal compelling evidence regarding the efficacy of homeopathic remedies [26-32]. For example, Mathie, Frye and Fisher show that there is â€œno significant difference between the effects of homeopathic Oscillococcinum® and placebo in prevention of influenza-like illness: risk ratio (RR) = 0.48, 95% confidence interval (CI) 0.17-1.34, p-value = 0.16 . The key reasons given for this failure to provide compelling evidence relate to low quality or unclear data, and lack of replicability, suggesting homeopathic remedies are unlikely to have clinical effects beyond placebo [26-32].
Sadly, the ACCC vs. Homeopathy Plus! Australia Pty Ltd is not the only case that has made headlines in Australia in recent years. An article in the Journal of Law and Medicine coincided with the NHMRC report regarding the number of deaths attributable to favouring homeopathy over conventional medical treatment in recent years . One such case was that of Jessica Ainscough, who passed away earlier this year after losing her battle with a rare form of cancer “epithelioid sarcoma“ after rejecting conventional treatment in favour of alternative therapies . Although doctors recognise Ms. Ainscough’s right to choose her own cancer treatments and understand why she refused the disfiguring surgery to save her life, they fear her message may influence others to reject conventional treatments that could ultimately save their lives . Another near death case was that of an eight-month-old boy whose mother was charged with â€œreckless grievous bodily harm and failure to provide for a child causing danger to deathâ€ after ceasing conventional medical and dermatological treatment for her son’s eczema as advised by her naturopath (an umbrella term that includes homeopathy) . The all-liquid treatment plan left the boy severely malnourished and consequently, he now suffers from developmental issues . This case is rather similar to that of R vs. Sam in 2009, where the parents of a nine-month-old girl were convicted of manslaughter by criminal negligence after favouring homeopathic treatment over conventional medical treatment for their daughter’s eczema. The girl died from septicaemia after her eczema became infected [36,37].[references are provided in the original document]

The NHMRC report stated that
Homeopathy should not be used to treat health conditions that are chronic, serious, or could become serious. People who choose homeopathy may put their health at risk if they reject or delay treatments for which there is good evidence for safety and effectiveness. People who are considering whether to use homeopathy should first get advice from a registered health practitioner. Those who use homeopathy should tell their health practitioner and should keep taking any prescribed treatments.
Few other reports have previously expressed our concerns about homeopathy so clearly – little wonder then that the world of homeopathy was (and still is) up in arms.
The last time something similar happened was during the Third Reich when homeopathy had been evaluated thoroughly by leading scientists and the conclusions turned out to be just as devastatingly negative. At the time, German homeopaths allegedly made the report disappear, and all we have today about this comprehensive research programme is a very detailed eye witness report of a homeopath who had been intimately involved in the research.
Today, it is thankfully no longer possible to make major research documents disappear. So, homeopaths have to think of other strategies to defend their trade. In the case of the NHMRC report, they act like all cults tend to do and resort to misleading statements and slanderous allegations. This, I feel, is unsurprising and will inevitably turn out to be unsuccessful.
The current volume of the ‘Allgemeinen Homöopathischen Zeitung’ contains all the abstracts of the ‘Homeopathic World Congress 2017’ which will be hosted in Leipzig, 14-17 July this year by the ‘Deutschen Zentralvereins Homöopathischer Ärzte’ under the patronage of the German Health Secretary, Annette Widmann-Mauz. As not many readers of this blog are likely to be regular readers of this important journal, I have copied six of the more amusing abstracts below:
A male patient with bilateral solid renal mass was investigated and given an individualized homeopathic remedy. Antimonium crudum in 50000 potency was selected after proper case taking and evaluation. Investigations were done before and after treatment. Follow ups took place monthly. Results The patient had symptomatic relief from pain in flanks, acute retention and hematuria. The ultrasonography suggests a reduction in size of both lesions over a period of two years. A small number of lymph nodes of the para-aortic group are still visible. There is a normal level of urea and creatinine, no anemia or hypertention. The patient is surviving since 2014. Conclusion In the present day when malignancies are treated with surgeries, chemo and radiotherapies, homeopathy has a significant role to play as seen in the above case. This case with bilateral solid renal mass, probably a renal cell carcinoma, received an individualized homeopathic remedy-treatment compliant with the totality of symptoms, and permitted the patient to live longer without anemia, hypertension, anorexia or weight loss. The quality of life was maintained without the side effects of surgery, radiotherapy and chemotherapy. Acute retentions, which he used to suffer also remained absent, thereafter. The result of this case suggests to take up further studies on individualized homeopathic treatment in malignant diseases.
Urinary tract infections (UTI) are often a complaint in the homeopathic practice, mainly as uncomplicated infections in the form of a one time event. Some patients, however, have a tendency to develop recurrent or complicated urinary tract infections. Methods It is shown on the basis of case documentation that UTI should be treated homeopathic, variably. The issue of prophylaxis will be discussed. Results If there is a tendency to complicated UTI, chronic treatment after case taking of the symptom-totality of the affected must take place during a free interval. In contrast, the chronically recurring and flaming up of UTI, as well as the uniquely occurring of uncomplicated UTI, are handled as an acute illness. The treatment is based on the striking, characteristic symptoms of the infected. Conclusion The homeopathic treatment of UTI in the acute case of uncomplicated forms is usually very successful, The chronic treatment of complicated UTI shows certain difficulties. A safe homeopathic prophylaxis, in terms of conventional medicine, is problematical.
The homeopathic clinic of the Municipal Public Servant Hospital of São Paulo (HSPM – Brazil) has among patient records some cases of thyroid gland diseases (hypothyroidism or hyperthyroidism), which were treated whith the systemic homeopathic method of Carillo. This study evaluates patients with diseases of thyroid gland, analyzing improvements using a Iodium-like equalizer, adjacent to the systemic medication. The reviewed 21 cases using Iodium equalizer for the disease, adjacent to the systemic medication, in the homeopathic clinic of the HSPM, from 2000 to 2013. In four cases, it was possible to reduce the dose of allopathic medicine and finally terminate it due to normalization of the thyroid gland function. There was one case of hyperthyroidism and it was possible to terminate the use of methimazole. There were four cases, in which the function of the thyroid gland was normalized without the associated use of hormone. In three cases it was possible to reduce the dose of hormone. There were nine cases, in which it was not possible to reduce the dose of the hormone. In cases where there was an improvement applying homeopathic treatment, TSH and free T4 returned to the normal reference value. In cases that were not effective, TSH and free T4 had not normalized. Therefore, the effectiveness of Iodium depends on the ability and stability of the gland thyroid to increase or decrease hormone production, in addition to the treatment of a chronic disease, that affects the thyroid gland.
Cystitis composes infections in the urinary system, especially bladder and urethra. It has multiple causes, but the most common is infection due to microorganisms such as E. coli, streptococcus, staphylococcus etc. If the system is attacked by pathogenetic agents, the defense must include more powerful noxious agents which can fight and destroy the attacking organisms, here is the role of nosodes. Nosodes are the potentised remedies made up from dangerous noxious materials. The use of nosodes in cystitis is based on the aphorism 26– Therapeutic Law of Nature: A weaker one is always distinguished by the stronger one! Colibacillinum, streptococcinum, staphylococcinum, lyssinum, medorrhinum, psorinum and tuberculinum are useful in handling cystitis relating to the organism involved [as found in urine test] and symptom similarity. Method An observational prospective study on a group of 30 people proves the immediate, stronger defensive action of nosodes. Result Amazing! Nosodes given in low potency provided instant relief to patients. Repetition of the same, over several months offered immunity for further attacks of cystitis, as Hering had already testified nosodes have prophylactic action. Conclusion According to law of similia – as per the pathology, as per the defense! By inducing a strong artificial disease, homeopathy can eliminate the natural disease from the body. Usually nosodes are used as intercurrent drugs which play the role of catalysts, on the journey to recovery, but they are also very effective in cystitis as an acute remedy. Acute cystitis is a very troublesome state for the patients, to cure it homeopathy has an arsenal of nosodes.
In 1991, no antiretroviral therapy (ART) treatment was available. The Central Council for Research in Homeopathy had established a clinical research unit at Mumbai for undertaking investigations in HIV/AIDS. So far 2502 cases have been enrolled for homeopathic treatment and three studies have been published since then. In this paper we will highlight the impact of long term homeopathic management of cases, which have been followed up for more than 15 years. Method The HIV positive cases enrolled in different studies are continuously being managed in this unit and even after study conclusion. All the cases are being treated solely with individualised homeopathy. The cases are assessed clinically (body weight, opportunistic infections, etc.) as well as in respect to CD4 counts and CD4/CD8 ratio. Results The CD4 count was maintained in all patients, except in one case. Three patients had the CD4 level in the range of 500–1200, four in the range of 300–500, one had a 272 CD4 count. There has been a decline of CD4/ CD8 ratio since baseline, but the patients have maintained their body weights and remained free from major HIV related illnesses and opportunistic infections. The frequently indicated remedies were pulsatilla pratensis, lycopodium clavatum, nux vomica,tuberculinum bovinum, natrum muriaticum, rhus toxicodendron, medorrhinum, arsenicum album, mercurius solubilis, thuja occidentalis, nitic acid, sulphur, bryonia alba and hepar sulph. Conclusion In the emergent scenario of drug resistance and adverse reactions of ART in HIV infections, there may be a possibility of employing homeopathy as an adjuvant therapy to existing standard ART treatment. Further studies are desirable.
In the last 20 years we have treated in the Clinica St. Croce many patients with cancer. We often deal with palliative states and we aim at pain relief and improvement of life-quality, and if possible a prolongation of life. Is this possible by prescribing a homeopathic therapy? Methodology The exact application and the knowledge of the responses to the Q-potencies often give indications for the correct choice of remedy. Acute conditions of pain often need a more frequent repetition of the C-potencies needed for pain relief. Results Even with severe pain or in so-called final stages homeopathy can offer great assistance. On the basis of case reports from Clinica St. Croce, the procedure for the homeopathic treatment of cancer, and the treatment of pain and final states will be illustrated and clarified. In addition, some clinically proven homeopathic remedies will be presented for the optimal palliation in the treatment of end-states and accompanying the dying. Conclusions With the precise application and knowledge of the responses to the Q- and C-potencies, the homeopathic doctor is given a wonderful helper to treat even the most serious palliative states and can accomplish, sometimes, a miraculous healing.
MY BRIEF COMMENT
These abstracts are truly hilarious and show how totally unaware some homeopaths are of the scientific method. I say ‘some’, but perhaps it is most or even all? How can a scientific committee reviewing these abstracts let them pass and allow the material to be presented at the ‘World Congress’? How can a Health Secretary accept the patronage of such a farce?
These abstracts are therefore not just hilarious but also truly depressing. If we had needed proof that homeopathy has no place in real healthcare of today, these abstracts would go a long way in providing it. To realise that politicians, physicians, patients, consumers, journalists etc. take such infantile nonsense seriously is not just depressing but at the same time worrying, I find.
The website of ‘HOMEOPATHY 360’ has just published a new post offering a handy instruction for killing patients suffering from acute appendicitis. If you do not believe me – I don’t blame you, I too found it hard to believe – read this short excerpt advocating homeopathy for this life-threatening condition (for readers without a medical background: if acute appendicitis is not treated promptly, the inflamed appendix might burst, spilling faecal material into the abdominal cavity, resulting in a life-threatening peritonitis):
The post is entitled “A Cure of Acute Appendicitis Using Frequent Homeopathic Doses in Solution”
Here is the abstract:
“Placing centesimal potencies in solution and prescribing them frequently for acute conditions is not widely practiced. It can be superior to dry doses in many cases, where a persistent mild medicinal action is preferred to a strong aggravation. By prescribing dissolved doses of Arnica Montana 1m, a case of acute appendicitis was cured quickly. This suggests that centesimal potencies given frequently in solution may be more efficacious, prompt and gentle than treatment with dry doses.”
Fascinating, isn’t it?
Here are more details demonstrating that the author has done his homework:
“When treating a patient with acute medical condition, in certain cases we fail to cure. Even though our case taking, evaluation, analysis, remedy and potency selection seem correct. What is the cause? In the Organon 5th edition (1833) Dr. Hahnemann introduced olfaction and dissolved centesimal remedies as a new method of administering doses. Around the year 1840 Hahnemann began to introduce LM potencies into his practice. From 1840 to 1843 he used both centesimal and LM potencies side by side in medicinal solutions. By these methods he hoped to avoid unwanted aggravations and provide rapid cure.
In some acute cases the aggravation can be discouragingly prolonged and often cannot be discerned from the patient’s own disease. Many times we change the original prescription which could very well have been the simillimum. In acute diseases, a dry dose will many times produce an unnecessary aggravation because of the patient’s increased susceptibility. I have much experience now with what I call a “watery dose.” To prepare it, one or two globules of size 10 are diluted in 15ml. of distilled water in which 5 drops of alcohol added with 20 to 30 succussions. From this solution 10 drops are added to another 15 ml of water, and from this solution 5 to 10 drops dose repeated according to the severity of the disease. In such diluted solutions the correct number of drops must be precise. Every time before taking the dose the solution is succussed 5 to 10 times. The same solution can be used for several days or weeks. Hahnemann recommended using carefully measured and dosed solutions with sensitive patients. Many times I have used this method with great success. It is not necessary to take 4 oz. to 8 oz. of water, Just fifteen ml. of distilled water is sufficient. This technique of dosing is also known as a split dose because it uses one or two pills in a solution that is then split over several days or weeks.
The results using this type of dosing can be very different from dry doses. There is continuous amelioration of the complaints without aggravation. This comes closer to the ideal of strengthening the weakened vital force than is seen when we simply produce a similar stronger artificial disease in the patient.”
The author also provides a detailed case history of a patient who survived this treatment (of course, without mentioning that acute appendicitis can, in rare cases, have a spontaneous recovery).
I would not recommend Arnica or any other homeopathic remedy for routine use in acute appendicitis (or any other condition) – unless, of course, you want to kill a maximum number of your patients suffering from this medical/surgical emergency.
The website of the HOMEOPATHY HUB gives us intriguing access to the brain of a homeopath. It tells us that “protecting patient choice is at the heart of everything we do. Homeopathy, which is the second largest system of medicine in the world, is a form of treatment which plays a vital role in the lives of hundreds of thousands of people across the UK. There is, however, a movement to try and withdraw homeopathy from the public and make homeopathic medicines difficult to secure. Our intention is to be a central “hub” for accurate information on current campaigns to retain access to homeopathy and details on how you can get involved and make your voice heard. Without public and patient support we will not be successful.”
Here are a few of the above statements that I find doubtful:
- protecting patient choice – choice requires reliable information; as we will see, this is not provided here;
- second largest system of medicine in the world – really?
- plays a vital role – where is the evidence for that claim?
- movement to try and withdraw homeopathy from the public and make homeopathic medicines difficult to secure – nobody works towards this aim, some people are trying to stop wasting public funds on useless therapies, but that’s quite different, I find;
The HOMEOPATHY HUB recently alerted its readers to the fact that the Charity Commission (CC) is currently conducting a public consultation on whether organisations promoting the use of complementary and alternative medicines (CAM) should have charitable status (https://www.gov.uk/government/consultations/consultation-on-complementary-and-alternative-medicines) and urged its readers to defend homeopathy by responding to the CC offering a “few helpful points” to raise. These 7 points give, I think, a good insight into the thinking of homeopaths. I therefore copy them here and add a few of my own comments below:
- there are many types of evidence that should be considered when evaluating the effectiveness of a therapy. These include scientific studies, patient feedback and the clinical experience of doctors who have trained in a CAM discipline. Within Homeopathy there is considerable evidence which can be found (https://www.hri-research.org)
- many conventional therapies and drugs have inconclusive evidence or prove to be useful in only some cases, for example SSRIs (anti-depressants). Inconsistent evidence is often the result of the complexity of both the medical condition being treated and the therapy being used. It is not indicative of a therapy that doesn’t work
- removing all therapies or interventions that have inconsistent or inconclusive evidence would seriously limit the public and the medical profession’s ability to help treat and ease patients suffering.
- all over the world there are doctors, nurses, midwives, vets and other healthcare professional who integrate CAM therapies into their daily practice because they see effectiveness. They would not use these therapies if they did not see their patients benefitting from them. For example in the UK, within the NHS hospital setting, outcome studies demonstrate effectiveness of homeopathy. (http://www.britishhomeopathic.org/evidence/results-from-the-homeopathic-hospitals/)
- practitioners of many CAM therapies belong to registering bodies which expect their members to comply to the highest professional standards in regards to training and practice
- In the UK the producers and suppliers of CAM treatments (homeopathy, herbal medicine etc) are strictly regulated
- as well as providing valuable information to the growing number of people seeking to use CAM as part of their healthcare, CAM charities frequently fund treatment for those people, particularly the elderly and those on a low income, whose health has benefitted from these therapies but who cannot afford them. This meets the charity’s criterion of providing a public benefit.
- “Patient feedback and the clinical experience of doctors” may be important but is not what can be considered evidence of therapeutic effectiveness.
- Yes, in medicine evidence is often inconsistent; this is why we need to rely on proper assessments of the totality of the reliable data. If that fails to be positive (as is the case for homeopathy and several other forms of alternative medicine), we are well advised not to employ the treatment in question in routine healthcare.
- Removing all treatments for which the best evidence fails to show effectiveness – such as homeopathy – would greatly improve healthcare and reduces cost. It is one of the aims of EBM and an ethical imperative.
- Yes, some healthcare professionals do use useless therapies. They urgently need to be educated in the principles of EBM. Outcome studies have normally no control groups and therefore are no adequate tools for testing the effectiveness of medical interventions.
- The highest professional standards in regards to training and practice of nonsense will still result in nonsense.
- The proper regulation of nonsense can only generate proper nonsense.
- Yes, CAM charities frequently fund bogus treatments; hopefully (and with the help of readers of this blog), the CC will put an end to this soon.
I think these 7 points by the HOMEOPATHY HUB are a very poor defence of homeopathy. In fact, they are so bad that it is not worth analysing more closely than I did above. Yet, they do provide us with an insight into the homeopathic mind-set and show how illogical, misguided and wrong the arguments of homeopathy enthusiasts really are.
I do encourage you to give your response to the CC – it wound be hard to use better arguments than the homeopaths!!!
Regular readers of this blog will have noticed: when homeopathy-fans run out of arguments, they tend to conduct an ‘ad hominem’ attack. They like to do this in several different ways, but one of the most popular version is to shout with indignation: YOU ARE NOT QUALIFIED!!!
The aim of this claim is to brand the opponent as someone who does not know enough about homeopathy to make valid comments about it. As this sort of thing comes up regularly, it is high time to ask: WHO ACTUALLY IS AN EXPERT IN HOMEOPATHY?
This seems to be an easy question to answer, but – come to think of it – it is more complex that one first imagines. Someone could be an expert in homeopathy in more than one way; for instance, one could be an expert:
- in the history of homeopathy,
- in the manufacture of homeopathics,
- in the regulation of homeopathy,
- in the clinical use of homeopathy in human patients,
- in the clinical use of homeopathy in animals,
- in the use of homeopathy in plants (no, I am not joking!),
- in basic research of homeopathy,
- in clinical research of homeopathy.
This blog is almost entirely devoted to clinical research; therefore, we should, for the purpose of this post, narrow down the above question to: WHO IS AN EXPERT IN CLINICAL RESEARCH OF HOMEOPATHY?
I had always assumed to be such an expert – until I was accused of being a swindler and pretender, that is. I have no formal qualifications for practising homeopathy (and never claimed otherwise), and this fact has prompted many homeopathy-fans to claim that I am not qualified to comment on the value of homeopathy. Do they have a point?
Rational thinkers have often pointed out that one does not need such qualifications for practicing homeopathy. In many countries, anyone can be a homeopath, regardless of background. In all the countries I know, one certainly can practise homeopathy, if one is qualified as a doctor. Crucially, do you really need to know how to practice homeopathy for conducting a clinical trial or a systematic review of homeopathy? Homeopaths seem to think so. I fear, however, that they are wrong: you don’t need to be a surgeon, psychiatrist or rheumatologist to organise a trial or conduct a review of these subjects!
Anyway, my research of homeopathy is not valid, homeopaths say, because I lack the formal qualifications to call myself a homeopath. Let me remind them that I have:
- been trained by leading homeopaths,
- practised homeopathy for quite some time,
- headed a team of scientists conducting research into homeopathy,
- conducted several clinical trials of homeopathy,
- published several systematic reviews of homeopathy,
- no conflicts of interest in regards to homeopathy.
However, this does not impress homeopath, I am afraid. They say that my findings and conclusions about their pet therapy cannot be trusted. In their eyes, I am not a competent expert in clinical research of homeopathy. They see me as a fraud and as an impostor. They prefer the real experts of clinical research of homeopathy such as:
- Robert Mathie
- Jos Kleinjen
- Klaus Linde
These three researchers who are fully accepted by homeopaths; not just accepted, loved and admired! They all have published systematic reviews. Intriguingly, their conclusion all contradict my results in one specific aspect: THEY ARE POSITIVE.
I do not doubt their expertise for a minute, yet have always found this most amusing, even hilarious.
Because none of these experts (I know all three personally) is a qualified homeopath, none of them has any training in the practice of homeopathy, none of them has ever practised homeopathy on human patients, none of them has even worked for any length of time as a clinician.
What can we conclude from these insights?
We could, of course, descend to the same level as homeopaths tend to do and conclude that homeopathy-fans are biased, barmy, bonkers, stupid, silly, irrational, deluded, etc. However, I prefer to draw a different and probably more accurate conclusion: according to homeopathy-fans, an expert in clinical research of homeopathy is someone who has published articles that are favourable to their trade. Anyone who fails to do likewise is by definition not competent to issue a reliable verdict about it.
As the data suggesting that homeopathy is effective for improving health is – to put it mildly – less than convincing, a frantic search is currently on amongst homeopaths and their followers to identify a specific condition for which the evidence is stronger than for all conditions pooled into one big analysis. If they could show that it works for just one disease, they could celebrate this finding and henceforth use it for refuting doubters stating that highly diluted homeopathic remedies are pure placebos. One such condition is allergic rhinitis; there have been several trials suggesting that homeopathy might be effective for it, and therefore it is only logical that homeopathy-promoters want to summarise these data in order to silence sceptics once and for all.
A new paper ought to be seen in this vein. It is systematic review by the Mathie group with the stated aim “to evaluate the efficacy and effectiveness of homeopathic intervention in the treatment of seasonal or perennial allergic rhinitis (AR).”
Randomized controlled trials evaluating all forms of homeopathic treatment for AR were included in a systematic review (SR) of studies published up to and including December 2015. Two authors independently screened potential studies, extracted data, and assessed risk of bias. Primary outcomes included symptom improvement and total quality-of-life score. Treatment effect size was quantified as mean difference (continuous data), or by risk ratio (RR) and odds ratio (dichotomous data), with 95% confidence intervals (CI). Meta-analysis was performed after assessing heterogeneity and risk of bias.
Eleven studies were eligible for SR. All trials were placebo-controlled except one. Six trials used the treatment approach known as isopathy, but they were unsuitable for meta-analysis due to problems of heterogeneity and data extraction. The overall standard of methods and reporting was poor: 8/11 trials were assessed as “high risk of bias”; only one trial, on isopathy for seasonal AR, possessed reliable evidence. Three trials of variable quality (all using Galphimia glauca for seasonal AR) were included in the meta-analysis: nasal symptom relief at 2 and 4 weeks (RR = 1.48 [95% CI 1.24-1.77] and 1.27 [95% CI 1.10-1.46], respectively) favoured homeopathy compared with placebo; ocular symptom relief at 2 and 4 weeks also favoured homeopathy (RR = 1.55 [95% CI 1.33-1.80] and 1.37 [95% CI 1.21-1.56], respectively). The single trial with reliable evidence had a small positive treatment effect without statistical significance. A homeopathic and a conventional nasal spray produced equivalent improvements in nasal and ocular symptoms.
The authors concluded that the low or uncertain overall quality of the evidence warrants caution in drawing firm conclusions about intervention effects. Use of either Galphimia glauca or a homeopathic nasal spray may have small beneficial effects on the nasal and ocular symptoms of AR. The efficacy of isopathic treatment of AR is unclear.
Extracts of Galphimia glauca (GG) have been used traditionally in South America for the treatment of allergic conditions, with some reports suggesting effectiveness. A 1997 meta-analysis of 11 clinical trials (most of them of very poor quality) of homeopathic GG suggested this therapy to be effective in the treatment of AR. In 2011, I published a review (FACT 2011, 16 200-203) focussed exclusively on the remarkable set of RCTs of homeopathic Galphimia glauca (GG). My conclusions were as follows: three of the four currently available placebo-controlled RCTs of homeopathic GG suggest this therapy is an effective symptomatic treatment for hay fever. There are, however, important caveats. Most essentially, independent replication would be required before GG can be considered for the routine treatment of hay fever. Since then, no new studies have emerged.
I am citing this for two main reasons:
- There is nothing homeopathic about the principle of using GG for allergic conditions; according to homeopathic theory GG extracts would need to cause allergies for GG to have potential as a homeopathic allergy remedy. Arguably, the GG trials should therefore have been excluded from this meta-analysis for not following the homeopathic principal of ‘like cures like’.
- All the RCTs of GG were done by the same German research group. There is not a single independent replication of their findings!
Seen from this perspective, the conclusion by Mathie et al, that the use of either Galphimia glauca … may have small beneficial effects on the nasal and ocular symptoms of AR, seems more than a little over-optimistic.
On this blog, we have had (mostly unproductive) discussions with homeopath so often that sometimes they sound like a broken disk. I don’t want to add to this kerfuffle; what I hope to do today is to summarise a certain line of argument which, from the homeopaths’ point of view, seems entirely logical. I do this in the form of a fictitious conversation between a scientist (S) and a classical homeopath (H). My aim is to make the reader understand homeopaths better so that, future debates might be better informed.
HERE WE GO:
S: I have studied the evidence from studies of homeopathy in some detail, and I have to tell you, it fails to show that homeopathy works.
H: This is not true! We have plenty of evidence to prove that patients get better after seeing a homeopath.
S: Yes, but this is not because of the remedy; it is due to non-specific effect like the empathetic consultation with a homeopath. If one controls for these factors in adequately designed trials, the result usually is negative.
I will re-phrase my claim: the evidence fails to show that highly diluted homeopathic remedies are more effective than placebos.
H: I disagree, there are positive studies as well.
S: Let’s not cherry pick. We must always consider the totality of the reliable evidence. We now have a meta-analysis published by homeopaths that demonstrates the ineffectiveness of homeopathy quite clearly.
H: This is because homeopathy was not used correctly in the primary trials. Homeopathy must be individualised for each unique patient; no two cases are alike! Remember: homeopathy is based on the principle that like cures like!!!
S: Are you saying that all other forms of using homeopathy are wrong?
H: They are certainly not adhering to what Hahnemann told us to do; therefore you cannot take their ineffectiveness as proof that homeopathy does not work.
S: This means that much, if not most of homeopathy as it is used today is to be condemned as fake.
H: I would not go that far, but it is definitely not the real thing; it does not obey the law of similars.
S: Let’s leave this to one side for the moment. If you insist on individualised homeopathy, I must tell you that this approach can also be tested in clinical trials.
H: I know; and there is a meta-analysis which proves that it is effective.
S: Not quite; it concluded that medicines prescribed in individualised homeopathy may have small, specific treatment effects. Findings are consistent with sub-group data available in a previous ‘global’ systematic review. The low or unclear overall quality of the evidence prompts caution in interpreting the findings. New high-quality RCT research is necessary to enable more decisive interpretation.
If you call this a proof of efficacy, I would have to disagree with you. The effect was tiny and at least two of the best studies relevant to the subject were left out. If anything, this paper is yet another proof that homeopathy is useless!
H: You simply don’t understand homeopathy enough to say that. I tried to tell you that the remedy must be carefully chosen to fit each unique patient. This is a very difficult task, and sometimes it is not successful – mainly because the homeopaths employed in clinical trials are not skilled enough to find it. This means that, in these studies, we will always have a certain failure rate which, in turn, is responsible for the small average effect size.
S: But these studies are always conducted by experienced homeopaths, and only the very best, most experienced homeopaths were chosen to cooperate in them. Your argument that the trials are negative because of the ineffectiveness of the homeopaths – rather than the ineffectiveness of homeopathy – is therefore nonsense.
H: This is what you say because you don’t understand homeopathy!
S: No, it is what you say because you don’t understand science. How else would you prove that your hypothesis is correct?
H: Simple! Just look at individual cases from the primary studies within this meta-analysis . You will see that there are always patients who did improve. These cases are the proof we need. The method of the RCT is only good for defining average effects; this is not what we should be looking at, and it is certainly not what homeopaths are interested in.
S: Are you saying that the method of the RCT is wrong?
H: It is not always wrong. Some RCTs of homeopathy are positive and do very clearly prove that homeopathy works. These are obviously the studies where homeopathy has been applied correctly. We have to make a meta-analysis of such trials, and you will see that the result turns out to be positive.
S: So, you claim that all the positive studies have used the correct method, while all the negative ones have used homeopathy incorrectly.
H: If you insist to put it like that, yes.
S: I see, you define a trial to have used homeopathy correctly by its result. Essentially you accept science only if it generates the outcome you like.
H: Yes, that sounds odd to you – because you don’t understand enough of homeopathy.
S: No, what you seem to insist on is nothing short of double standards. Or would you accept a drug company claiming: some patients did feel better after taking our new drug, and this is proof that it works?
H: You see, not understanding homeopathy leads to serious errors.
S: I give up.
The aim of this paper was to systematically review surveys of 12-month prevalence of homeopathy use by the general population worldwide. Studies were identified via database searches to October 2015. Study quality was assessed using a six-item tool. All estimates were in the context of a survey which also reported prevalence of any complementary and alternative medicine use. A total of 36 surveys were included. Of these, 67% met four of six quality criteria.
Twelve-month prevalence of treatment by a homeopath was reported in 24 surveys of adults (median 1.5%, range 0.2–8.2%). Estimates for children were similar to those for adults. Rates in the USA, UK, Australia and Canada all ranged from 0.2% to 2.9% and remained stable over the years surveyed (1986–2012). Twelve-month prevalence of all use of homeopathy (purchase of over-the-counter homeopathic medicines and treatment by a homeopath) was reported in 10 surveys of adults (median 3.9%, range 0.7–9.8%) while a further 11 surveys which did not define the type of homeopathy use reported similar data. Rates in the USA and Australia ranged from 1.7% to 4.4% and remained stable over the years surveyed. The highest use was reported by a survey in Switzerland where homeopathy is covered by mandatory health insurance.
The authors concluded that each year a small but significant percentage of these general populations use homeopathy. This includes visits to homeopaths as well as purchase of over-the-counter homeopathic medicines.
These data thus indicate that the percentage of the adult general population using homeopathy over the previous 12 months was in the range of 0.7–9.8%, with a median estimate of 3.9%, and the percentage accessing treatment by a homeopath over the previous 12 months was in the range of 0.2–8.2%, with a median estimate of 1.5%. The data also suggest that, over the last few decades, use of homeopathy has remained fairly stable. These facts are in sharp contrast to the claims by homeopaths that:
- Homeopathy is hugely popular.
- Homeopathy is being used by more and more people across the globe.
- Homeopathy is the medicine of the future.
The well-documented and undeniable unpopularity of homeopathy begs the question, I think, why so many people seem to get so excited about homeopathy. The level of usage is nothing to write home about! Therefore, why don’t we just put it down to an aberration like believing the earth is flat? Why don’t we just concede that some minor, harmless stupidity will always exist in some people’s minds?
Here are some reasons why:
- It is not about the amount of people using homeopathy, but about the principle that any of the increasingly scarce public funds for healthcare are wasted on something as irrational and useless as homeopathy.
- Homeopathy makes a mockery of EBM.
- Homeopathy and homeopaths are by no means harmless.
- Homeopaths tell too many lies to be allowed to get away with them.
- Homeopathy and its followers systematically undermine rational thought.
The ‘SOCIETY OF HOMEOPATHS’ (SoH) have published an official complaint they recently filed with the BBC. As it gives an intriguing insight into their mind-set, I could not resist reproducing it here (warts and all):
“Prompted by the interview with Simon Stevens of NHS England on the Today Programme, on 31st March, the Society of Homeopaths deplores the lack of balance in the BBC’s coverage of Homeopathy and urges you to review your approach to coverage of the subject.
During the Today interview, following wide-ranging discussion of issues around the future of the NHS, Sarah Montague suddenly threw in a question about the amount spent on Homeopathy within the NHS, evidently catching Mr Stevens unawares.
The annual budget of the NHS is approximately £110billion. Of this, £4million per year (0.0036 of the NHS budget) is spent on Homeopathy. This hardly justifies the unbalanced and hectoring approach from Sarah Montague.
We acknowledge that it is not always possible or necessary to achieve balance on a particular topic within a single programme but the BBC seems to have a consistent line across all of its platforms of opposition to, and disparagement of, Homeopathy. A recent example is a piece on the Health section of the BBC website in October 2106 by Nick Tiggle which displayed no balance at all and denigrated Homeopathy and Homeopaths with little or no space given to alternative views.
From these and other instances, it seems clear that the BBC has a biased attitude towards Homeopathy, which may be the result of relying too heavily on a small number of ‘experts’, who openly and persistently campaign against complementary and alternative medicine. These ‘experts’ operate in a similar way to climate change deniers, referring to a limited range of research, often of poor quality, to support their claims that there is ‘no evidence for homeopathy’.
We look forward to BBC programmes which fulfill its mission to explain and provide balance and coverage of the positive effects of Homeopathy.
Mark Taylor Chief Executive Society of Homeopaths”
END OF QUOTE
This hardly needs a comment – perhaps just 6 short points:
- To the best of my knowledge, the BBC has a policy of not being seen to be biased. The discussion referred to above was about the NHS stopping to pay for treatments that are either not effective (e. g. cough syrups) or cheaper to buy OTC than on prescription (e. g. paracetamol). Homeopathy is both. Therefore it would have even been biased NOT to bring homeopathy into the discussion.
- To claim the BBC-interviewer caught Stevens off guard is just silly: when you go on the radio to discuss such issues, homeopathy MUST be on your mind.
- To claim that the BBC is generally biased against homeopathy (on the basis of two anecdotes) is equally silly. The SoH should have done some systematic research on this – perhaps they did and found it failed to support their point? – this would have shown that there is plenty of (far too much) pro-homeopathy stuff on the BBC.
- To say or imply that homeopathy is of debatable or even no value to the NHS does not disclose bias; on the contrary, it is a reflection of the scientific truth which the BBC has an obligation to report.
- With their complaint, the SoH disclose an embarrassing degree of naivety and an alarming detachment from reality.
- Whichever way a rational observer might look at this, the BBC should in future become a much more outspoken defender of the scientific truth – on homeopathy and everything else!!!
The recent meta-analysis by Mathie et al for non-individualised homeopathy (recently discussed here) identified just 3 RCTs that were rated as ‘reliable evidence’. But just how rigorous are these ‘best’ studies? Let’s find out!
THE FIRST STUDY
The objective of the first trial was “to evaluate the efficacy of the non-hormonal treatment BRN-01 in reducing hot flashes in menopausal women.” Its design was that of a multicentre (35 centres in France), randomized, double-blind, placebo-controlled. One hundred and eight menopausal women, ≥50 years of age, were enrolled in the study. The eligibility criteria included menopause for <24 months and ≥5 hot flashes per day with a significant negative effect on the women’s professional and/or personal life. Treatment was either BRN-01 tablets, a registered homeopathic medicine [not registered in the UK] containing Actaea racemosa (4 centesimal dilutions [4CH]), Arnica montana (4CH), Glonoinum (4CH), Lachesis mutus (5CH), and Sanguinaria canadensis (4CH), or placebo tablets, prepared by Laboratoires Boiron according to European Pharmacopoeia standards [available OTC in France]. Oral treatment (2 to 4 tablets per day) was started on day 3 after study enrolment and was continued for 12 weeks. The main outcome measure was the hot flash score (HFS) compared before, during, and after treatment. Secondary outcome criteria were the quality of life (QoL) [measured using the Hot Flash Related Daily Interference Scale (HFRDIS)], severity of symptoms (measured using the Menopause Rating Scale), evolution of the mean dosage, and compliance. All adverse events (AEs) were recorded. One hundred and one women were included in the final analysis (intent-to-treat population: BRN-01, n = 50; placebo, n = 51). The global HFS over the 12 weeks, assessed as the area under the curve (AUC) adjusted for baseline values, was significantly lower in the BRN-01 group than in the placebo group (mean ± SD 88.2 ± 6.5 versus 107.2 ± 6.4; p = 0.0411). BRN-01 was well tolerated; the frequency of AEs was similar in the two treatment groups, and no serious AEs were attributable to BRN-01. The authors concluded that BRN-01 seemed to have a significant effect on the HFS, compared with placebo. According to the results of this clinical trial, BRN-01 may be considered a new therapeutic option with a safe profile for hot flashes in menopausal women who do not want or are not able to take hormone replacement therapy or other recognized treatments for this indication.
Laboratoires Boiron provided BRN-01, its matching placebo, and financial support for the study. Randomization and allocation were carried out centrally by Laboratoires Boiron. I would argue that the treatment time in this study was way too short for generating a therapeutic response. The evolution of the HFS in the two groups was assessed by analysis of the area under the curve (AUC) of the mean scores recorded weekly from each patient in each group over the duration of the study, including those at enrollment (before any treatment). I wonder whether this method was chosen only when the researchers noted that the HFS at the pre-defined time points did not yield a significant result or whether it was pre-determined (elsewhere in the methods section we are told that “The primary evaluation criterion was the effect of BRN-01 on the HFS, compared with placebo. The HFS was defined as the product of the daily frequency and intensity of all hot flashes experienced by the patient, graded by the women from 1 to 4 (1 = mild; 2 = moderate; 3 = strong; 4 = very strong). These data were recorded by the women on a self-administered questionnaire, assisted by a telephone call from a clinical research associate. Data were collected (i) during the first 2 days after enrolment and before any medication had been taken; (ii) then every Tuesday and Wednesday of each week until the 11th week of treatment, inclusive; and (iii) finally, every day of the 12th week of treatment.”). Two of the authors of this paper are employees of Boiron.
THE SECOND STUDY
The second trial was aimed at finding out “whether a well-known and frequently prescribed homeopathic preparation could mitigate post-operative pain.” It was a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of the homeopathic preparation Traumeel S® in minimizing post-operative pain and analgesic consumption following surgical correction of hallux valgus. Eighty consecutive patients were randomized to receive either Traumeel tablets or an indistinguishable placebo, and took primary and rescue oral analgesics as needed. Maximum numerical pain scores at rest and consumption of oral analgesics were recorded on day of surgery and for 13 days following surgery. Traumeel was not found superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial, however a transient reduction in the daily maximum post-operative pain score favoring the Traumeel arm was observed on the day of surgery, a finding supported by a treatment-time interaction test (p = 0.04). The authors concluded that Traumeel was not superior to placebo in minimizing pain or analgesic consumption over the 14 days of the trial. A transient reduction in the daily maximum post-operative pain score on the day of surgery is of questionable clinical importance.
Traumeel is a mixture of 6 ingredients, 4 of which are in the D2 potency. Thus it neither is administered as a homeopathic remedy (no ‘like cures like’) nor is it highly diluted. In fact, it is not homeopathy at all but belongs to a weird offspring of homeopathy called ‘homotoxicology’ [this is an explanation from my book: Homotoxicology is a method inspired by homeopathy which was developed by Hans Heinrich Reckeweg (1905 – 1985). He believed that all or most illness is caused by an overload of toxins in the body. The toxins originate, according to Reckeweg, both from the environment and from the malfunction of physiological processes within the body. His treatment consists mainly in applying homeopathic remedies which usually consist of combinations of single remedies, because health cannot be achieved without ridding the body of toxins. The largest manufacturer and promoter of remedies used in homotoxicology is the German firm Heel.] The HEEL Company (Baden-Baden, Germany) provided funding for the performance and monitoring of this project, supplied the study medication and placebo, and prepared the randomization list. The positive outcome mentioned in the authors’ conclusion refers to a secondary endpoint. I would argue that the authors should not have noted it there and should have made it clear that the trial generated a negative result.
THE THIRD STUDY
Finally, the third of the 3 ‘rigorous’ studies “evaluated the effectiveness of the homeopathic preparation Plumbum Metallicum (PM) in reducing the blood lead levels of workers exposed to this metal.” The Brazilian researchers recruited 131 workers to this RCT who took PM in the CH15 potency or placebo for 35 days (10 drops twice daily). Thereafter, the percentage of workers whose lead level had fallen by at least 25% did not differ between the groups, both on intention to treat and per protocol analyses. The authors concluded that PM “had no effect in this study in terms of reducing serum lead in workers exposed to lead.”
This study lacks a power calculation, and arguably the period might have been too short to show an effect. The trial was published in the journal HOMEOPATHY which, some might argue, has not the most rigorous of peer-review procedures.
The third study seems the most rigorous by far, in my view. The other two trials are seriously under-whelming in several respects, primarily because we cannot be sure how much influence the commercial interests of the sponsor had on their findings. I am sure others will spot weaknesses in all three trials that I failed to see.
Mathie et al partly disagree with my assessment when they write in their paper: “We report separately our model validity assessments of these trials, evaluating consequently their overall quality based on a GRADE-like principle of ‘downgrading’ : two trials [23, 25] rated here as reliable evidence were downgraded to ‘low quality’ overall due to the inadequacy of their model validity; the remaining trial with reliable evidence  was judged to have adequate model validity. The latter study  thus comprises the sole RCT that can be designated ‘high quality’ overall by our approach, a stark finding that reveals further important aspects of the preponderantly low quality of the current body of evidence in non-individualised homeopathy.”
What Mathie et al seem to forget entirely is that none of the 3 RCTs is a trial of homeopathy as defined by treatment according to the ‘like cures like’ principle. The authors of the second study acknowledge this fact by stating: “Homeopathic purists may find fault in the administration of a standardized combination homeopathic formula to all patients, based upon clinical diagnosis – as opposed to the individualized manner dictated by standard homeopathic practice.”
So, which ever way we look upon this evidence, we cannot possibly deny that the evidence for non-individualised homeopathy is rubbish.
