In this RCT tested the effectiveness of foot reflexology and slow stroke back massage on the severity of fatigue in 52 patients treated with hemodialysis. Foot massage and slow stroke back massage were performed during three weeks, two sessions each week, 5 sessions in total. At the end of intervention, data of two groups were collected and compared.
The results show that the fatigue in the group receiving foot reflexology massage decreased significantly more compared to slow stroke back massage group.
The authors concluded that reflexology massage is a safe and economical nursing intervention for decreasing fatigue in hemodialysis patients.
At first glance, this might be a fairly straight forward study comparing two different interventions. One treatment yields better results than the other one, and therefore, this therapy is deemed to be the more effective one.
So far, so good.
The problem is, however, that the authors did not draw the conclusion. Instead they stated that:
- Reflexology is safe.
- Reflexology is economical.
The first point is perhaps true but cannot be concluded from the data presented. Adverse effects were not mentioned; and even if they had been noted, 52 patients is a wholly inadequate size to say anything about safety.
The second point might also be correct, but cannot be named as a conclusion, because the study was not a cost evaluation.
All of this would be hardly worth mentioning – except for the fact that such sloppy errors and illogical conclusions happen with such embarrassing regularity in the realm of alternative medicine. I feel strongly that the ‘Journal of Complementary and Integrative Medicine‘ and all similar publications must get their act together. Publishing articles such as the one discussed here only makes them the laughing stock of real scientists.
Mini-scalpel acupuncture or acupotomy is a relatively new type of non-invasive acupuncture/ micro surgery using a small needle-scalpel invented by Professor Zhu Hanzhang around 30 years ago in China. It is a slightly thicker and more blunt instrument that gets under the skin and is able to break apart adhesions and muscle knots more effectively than a regular acupuncture needle would.
Never mind, the question is does it work!
A systematic review showed that almost all studies reported an effect of acupotomy on joint pain compared to a variety of controls. On reflection, this is hardly surprising:
- all the trials were from China;
- all had major methodological flaws.
This means that we need better studies to decide the efficacy question.
This new study investigated the efficacy and safety of mini-scalpel acupuncture (MA) for knee osteoarthritis (KOA) in an assessor-blinded randomized controlled pilot trial; this would provide information for a large-scale randomized controlled trial.
Participants (n = 24) were recruited and randomly allocated to the MA group (experimental) or acupuncture group (control). The MA group received treatment once a week for 3 weeks (total of 3 treatments), while the acupuncture group received treatment two times per week for 3 weeks (total of 6 treatments). The primary outcome was pain as assessed by a visual analogue scale (VAS). The secondary outcomes (intensity of current pain, stiffness, and physical function) were assessed using the short-form McGill Pain Questionnaire (SF-MPQ) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Assessments were performed at baseline, 1, 2, and 3 during treatment and at week 5 (2 weeks after the end of treatment).
Of the 24 participants, 23 completed the study. Both groups showed significant improvements in VAS, SF-MPQ, and WOMAC. There were no significant differences between the MA and acupuncture groups. No serious adverse event occurred and blood test results were within normal limits.
The authors concluded that although both MA and acupuncture provide similar effects with regard to pain control in patients with KOA, MA may be more effective in providing pain relief because the same relief was obtained with fewer treatments. A large-scale clinical study is warranted to further clarify these findings.
I can recommend this article to anyone who wants a quick introduction into the critical analysis of clinical trials. It is a veritable treasure trove of mistakes, flaws, errors, fallacies etc. Here are just a few:
- The authors aim of investigating the safety of MA is unobtainable. It would require not 24 but probably 24 000 patients.
- The authors aim of investigating the efficacy of MA is equally unobtainable. It would require a much larger sample than 24, a sham control arm, identical treatment schedules, patient-blinding, etc.
- Calling the trial a ‘pilot’ is endearing but, except for the title and the insufficient sample size, this study has none of the characteristics of a pilot study.
- In their ‘introduction’, the authors state that miniscalpel acupuncture (MA) is a new subtype of acupuncture that is effective in treating chronic soft tissue injuries such as adhesions and contractures. This is clearly wrong but discloses their bias very plainly.
- The authors statement that both MA and acupuncture provide similar effects with regard to pain control in patients with KOA is misleading. It implies that both interventions had specific effects. Without a sham control arm, this is pure speculation.
- Similarly their assumption that MA may be more effective in providing pain relief because the same relief was obtained with fewer treatments, is pure fantasy.
- In fact, as MA requires injections of local anaesthetics, any outcome is heavily confounded by this addition.
- In the discussion section, the authors state that because MA is invasive and provides a strong stimulus, some participants complained of stiff and dull pain for few days after treatment. Yet, when reporting adverse effects in the results section, this was not mentioned.
- The way this study was designed, it should have been clear from the start that it would not produce any meaningful findings. Seen from this perspective, running the trial could even be seen as a breach of research ethics.
- According to the aims of a pilot study and the authors hope that their study would provide information for a large-scale randomized controlled trial, all reporting of outcomes is misplaced and should be replaced by information as to how a definitive trial should be conducted.
The following footnote is worth mentioning: This study is supported by a grant from the Ministry of Health & Welfare, Korea. It suggests to me that this ministry should urgently re-think its funding strategy and recruit some reviewers who are capable of critical analysis.
In my view, this is a lousy study which the authors decides to call ‘a pilot’ in order to get it published in a lousy journal.
Chiropractic is a therapy that has been in search for an indication ever since it was invented some 120 years ago. So far, this search seems to have been unsuccessful.
Perhaps it could be promoted as a means of enhancing athletic performance?
That would be excellent news for chiropractic cash-flow!
The authors of this study wanted to analyse the acute effects of spinal manipulative therapy (SMT) on performance and autonomic modulation. A total of 37 male recreational athletes who had never received SMT were assigned to a sham (n = 19) or actual SMT group (n = 18). Study endpoints included autonomic modulation (heart rate variability), handgrip strength, jumping ability and cycling performance (8-minute time trial [TT]). Differences in custom effects between interventions were determined using magnitude-based inferences.
A significant and very likely lower value of a marker of sympathetic modulation, the stress score, was observed in response to actual compared to sham SMT (p = 0.007; effect size [ES] = -0.97). A trend towards a significant and likely lower sympathetic:parasympathetic ratio (p = 0.055; ES = -0.96) and a likely higher natural logarithm of the root-mean-square differences of successive heartbeat intervals ([LnRMSSD], p = 0.12; ES = 0.36) was also found with actual SMT. Moreover, a significantly lower mean power output was observed during the TT with actual compared with sham SMT (p = 0.035; ES = -0.28). Non-significant (p > 0.05) and unclear or likely trivial differences (ES < 0.2) were found for the rest of endpoints, including handgrip strength, heart rate during the TT, and jump loss thereafter.
A single pre-exercise SMT session induced an acute shift towards parasympathetic dominance and slightly impaired performance in recreational healthy athletes.
The search was unsuccessful yet again!
SMT impaired performance; this might not convince athletes to become fans of chiropractic.
What indication should the desperate chiros try next?
One theory as to how acupuncture works is that it increases endorphin levels in the brain. These ‘feel-good’ chemicals could theoretically be helpful for weaning alcohol-dependent people off alcohol. So, for once, we might have a (semi-) plausible mechanism as to how acupuncture could be clinically effective. But a ‘beautiful hypothesis’ does not necessarily mean acupuncture works for alcohol dependence. To answer this question, we need clinical trials or systematic reviews of clinical trials.
A new systematic review assessed the effects and safety of acupuncture for alcohol withdrawal syndrome (AWS). All RCTs of drug plus acupuncture or acupuncture alone for the treatment of AWS were included. Eleven RCTs with a total of 875 participants were included. In the acute phase, two trials reported no difference between drug plus acupuncture and drug plus sham acupuncture in the reduction of craving for alcohol; however, two positive trials reported that drug plus acupuncture was superior to drug alone in the alleviation of psychological symptoms. In the protracted phase, one trial reported acupuncture was superior to sham acupuncture in reducing the craving for alcohol, one trial reported no difference between acupuncture and drug (disulfiram), and one trial reported acupuncture was superior to sham acupuncture for the alleviation of psychological symptoms. Adverse effects were tolerable and not severe.
The authors concluded that there was no significant difference between acupuncture (plus drug) and sham acupuncture (plus drug) with respect to the primary outcome measure of craving for alcohol among participants with AWS, and no difference in completion rates (pooled results). There was limited evidence from individual trials that acupuncture may reduce alcohol craving in the protracted phase and help alleviate psychological symptoms; however, given concerns about the quantity and quality of included studies, further large-scale and well-conducted RCTs are needed.
There is little to add here. Perhaps just two short points:
1. The quality of the trials was poor; only one study of the 11 trials was of acceptable rigor. Here is its abstract:
We report clinical data on the efficacy of acupuncture for alcohol dependence. 503 patients whose primary substance of abuse was alcohol participated in this randomized, single blind, placebo controlled trial. Patients were assigned to either specific acupuncture, nonspecific acupuncture, symptom based acupuncture or convention treatment alone. Alcohol use was assessed, along with depression, anxiety, functional status, and preference for therapy. This article will focus on results pertaining to alcohol use. Significant improvement was shown on nearly all measures. There were few differences associated with treatment assignment and there were no treatment differences on alcohol use measures, although 49% of subjects reported acupuncture reduced their desire for alcohol. The placebo and preference for treatment measures did not materially effect the results. Generally, acupuncture was not found to make a significant contribution over and above that achieved by conventional treatment alone in reduction of alcohol use.
To me, this does not sound all that encouraging.
2. Of the 11 RCTs, 8 failed to report on adverse effects of acupuncture. In my book, this means these trials were in violation with basic research ethics.
My conclusion of all this: another ugly fact kills a beautiful hypothesis.
Acupuncture research does not have a good name; if it originates from China, even less so.
And this note in ‘ACUPUNCTURE IN MEDICINE’ is not likely to change this image:
Fang J, Keller CL, Chen L, et al. Effect of acupuncture and Chinese herbal medicine on subacute stroke outcomes: a single-centre randomised controlled trial. Acupuncture in Medicine Published online first 10 November 2017. doi: 10.1136/acupmed-2016-011167.
This article is retracted by the Editor-in-Chief on grounds of redundant publication.
The above article reports that a trial originally planned to be carried out at three hospitals was reduced to a single centre for reasons of cost. This is incorrect. The full three-centre trial was run and reported elsewhere (Scientific Reports 6, Article number: 25850 (2016) DOI: 10.1038/srep25850).
The Scientific Reports paper was accepted for publication prior to submission of the above paper to Acupuncture in Medicine. The third author takes responsibility for the mistake. All authors have agreed to this retraction.
The abstract of the paper in SCIENTIFIC REPORTS is here:
To determine whether integrative medicine rehabilitation (IMR) that combines conventional rehabilitation (CR) with acupuncture and Chinese herbal medicine has better effects for subacute stroke than CR alone, we conducted a multicenter randomized controlled trial that involved three hospitals in China. Three hundred sixty patients with subacute stroke were randomized into IMR and CR groups. The primary outcome was the Modified Barthel Index (MBI). The secondary outcomes were the National Institutes of Health Stroke Scale (NIHSS), the Fugl-Meyer Assessment (FMA), the mini-mental state examination (MMSE), the Montreal Cognitive Assessment (MoCA), Hamilton’s Depression Scale (HAMD), and the Self-Rating Depression Scale (SDS). All variables were evaluated at week 0 (baseline), week 4 (half-way of intervention), week 8 (after treatment) and week 20 (follow-up). In comparison with the CR group, the IMR group had significantly better improvements (P < 0.01 or P < 0.05) in all the primary and secondary outcomes. There were also significantly better changes from baseline in theses outcomes in the IMR group than in the CR group (P < 0.01). A low incidence of adverse events with mild symptoms was observed in the IMR group. We conclude that conventional rehabilitation combined with integrative medicine is safe and more effective for subacute stroke rehabilitation.
I find all this odd in several ways:
- The publication of the ACUPUNCTURE IN MEDICINE article does not seem to have been a ‘mistake‘ but plain scientific fraud, in my view.
- The paper in SCIENTIFIC REPORTS (SR) was published in May 2016. Therefore the reviewers and editor of AIM could and should have spotted the fraud.
- In the SR paper, the authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article. As the authors were affiliated to three different departments of acupuncture, I feel this to be debatable.
What do you think?
The authors of this paper wanted to establish and compare the effectiveness of Healing Touch (HT) and Oncology Massage (OM) therapies on cancer patients’ pain. They conducted pre-test/post-test, observational, retrospective study. A total of 572 outpatient oncology were recruited and asked to report pain before and after receiving a single session of either HT or OM from a certified practitioner.
Both HT and OM significantly reduced pain. Unadjusted rates of clinically significant pain improvement (defined as ≥2-point reduction in pain score) were 0.68 HT and 0.71 OM. Adjusted for pre-therapy pain, OM was associated with increased odds of pain improvement. For patients with severe pre-therapy pain, OM was not more effective in yielding clinically significant pain reduction when adjusting for pre-therapy pain score.
The authors concluded that both HT and OM provided immediate pain relief. Future research should explore the duration of pain relief, patient attitudes about HT compared with OM, and how this may differ among patients with varied pretherapy pain levels.
This paper made me laugh out loud; no, not because of the ‘certified’ practitioners (in the UK, we use this term to indicate that someone is not quite sane), but because of the admission that the authors aimed at establishing the effectiveness of their therapies. Most researchers of alternative medicine have exactly this motivation, but few make the mistake to write it into the abstract of their papers. Little do they know that this admission discloses a fatal amount of bias. Science is supposed to test hypotheses, and researchers who aim at establishing the effectiveness of their pet-therapy oust themselves as pseudo-researchers.
It comes therefore as no surprise that the study turns out to be a pseudo-study. As there was no adequate control group, these outcomes cannot be attributed to the interventions administered. The results could therefore be due to:
- the time that has passed;
- regression to the mean;
- the attention provided by the therapists;
- the expectation of the patient;
- social desirability;
- all of the above.
It follows that – just as with the study discussed in the previous post – the conclusion is wholly misleading. In fact, the data are consistent with the hypothesis that HT and OM both aggravated the pain (the results might have been better without HT and OM). The devils advocate concludes that both HT and OM provided an immediate increase in pain.
This study was aimed at evaluating group-level and individual-level change in health-related quality of life among persons with chronic low back pain or neck pain receiving chiropractic care in the United States.
A 3-month longitudinal study was conducted of 2,024 patients with chronic low back pain or neck pain receiving care from 125 chiropractic clinics at 6 locations throughout the US. Ninety-one percent of the sample completed the baseline and 3-month follow-up survey (n = 1,835). Average age was 49, 74% females, and most of the sample had a college degree, were non-Hispanic White, worked full-time, and had an annual income of $60,000 or more. Group-level and individual-level changes on the Patient-Reported Outcomes Measurement Information System (PROMIS) v2.0 profile measure were evaluated: 6 multi-item scales (physical functioning, pain, fatigue, sleep disturbance, social health, emotional distress) and physical and mental health summary scores.
Within group t-tests indicated significant group-level change for all scores except for emotional distress, and these changes represented small improvements in health. From 13% (physical functioning) to 30% (PROMIS-29 Mental Health Summary Score) got better from baseline to 3 months later.
The authors concluded that chiropractic care was associated with significant group-level improvement in health-related quality of life over time, especially in pain. But only a minority of the individuals in the sample got significantly better (“responders”). This study suggests some benefits of chiropractic on functioning and well-being of patients with low back pain or neck pain.
These conclusions are worded carefully to avoid any statement of cause and effect. But I nevertheless feel that the authors strongly imply that chiropractic caused the observed outcomes. This is perhaps most obvious when they state that this study suggests some benefits of chiropractic on functioning and well-being of patients with low back pain or neck pain.
To me, it is obvious that this is wrong. The data are just as consistent with the opposite conclusion. There was no control group. It is therefore conceivable that the patients would have improved more and/or faster, if they had never consulted a chiropractor. The devil’s advocate therefore concludes this: the results of this study suggest that chiropractic has significant detrimental effects on functioning and well-being of patients with low back pain or neck pain.
Try to prove me wrong!
I am concerned that a leading journal (Spine) publishes such rubbish.
The ‘Schwaebische Tageblatt’ is not on my regular reading list. But this article of yesterday (16/10/2018) did catch my attention. For those who read German, I will copy it below, and for those who don’t I will provide a brief summary and comment thereafter:
Die grün-schwarze Landesregierung lässt 2019 den ersten Lehrstuhl für Naturheilkunde und Integrative Medizin in Baden-Württemberg einrichten. Lehrstuhl für Naturheilkunde und Integrative Medizin
Ihren Schwerpunkt soll die Professur im Bereich Onkologie haben. Strömungen wie Homöopathie oder Anthroposophie sollen nicht gelehrt, aber innerhalb der Lehre beleuchtet werden, sagte Ingo Autenrieth, Dekan der Medizinischen Fakultät in Tübingen am Dienstag der Deutschen Presse-Agentur. «Ideologien und alles, was nichts mit Wissenschaft zu tun hat, sortieren wir aus.»
Die Professur soll sich demnach mit Themen wie Ernährung, Probiotika und Akupunktur beschäftigten. Geplant ist laut Wissenschaftsministerium, die Lehre in Tübingen anzusiedeln; die Erforschung der komplementären Therapien soll vorwiegend am Centrum für Tumorerkrankungen des Robert-Bosch-Krankenhauses in Stuttgart stattfinden. Die Robert-Bosch-Stiftung finanziert die Professur in den ersten fünf Jahren mit insgesamt 1,84 Millionen Euro, danach soll das Land die Mittel dafür bereitstellen.
«Naturheilkunde und komplementäre Behandlungsmethoden werden von vielen Menschen ganz selbstverständlich genutzt, beispielsweise zur Ergänzung konventioneller Therapieangebote», begründete Wissenschaftsministerin Theresia Bauer (Grüne) das Engagement. Sogenannte sanfte oder natürliche Methoden könnten schwere Krankheiten wie etwa Krebs alleine nicht heilen, heißt es in einer Mitteilung des Ministeriums. Wissenschaftliche Ergebnisse zeigten aber, dass sie häufig zu Therapieerfolgen beitragen könnten, da sie den Patienten helfen, schulmedizinische Therapien gut zu überstehen – etwa die schweren Nebenwirkungen von Chemotherapien mindern.
Im Gegensatz zur Schulmedizin gebe es bisher aber kaum kontrollierte klinische Studien zur Wirksamkeit solcher Therapien, ergänzte Ingo Autenrieth. Ihre Erforschung am neuen Lehrstuhl solle Patienten Sicherheit bringen und ermöglichen, dass die gesetzlichen Krankenkassen die Kosten dafür übernehmen.
Hersteller alternativer Arzneimittel loben den Schritt der Politik. «Baden-Württemberg nimmt damit eine Vorreiterrolle in Deutschland und in Europa ein», heißt es beim Unternehmen Wala Heilmittel GmbH in Bad Boll. Die Landesregierung trage mit der Entscheidung dem Wunsch vieler Patienten und Ärzte nach umfassenden Behandlungskonzepten Rechnung.
Auch hoffen die Unternehmen, dass Licht in die oft kritische Debatte um Homöopathie gebracht wird. «Wir sehen mit Erstaunen und Befremden, dass eine bewährte Therapierichtung wie die Homöopathie, die Teil der Vielfalt des therapeutischen Angebots in Deutschland ist, diskreditiert werden soll», sagte ein Sprecher des Herstellers Weleda AG mit Sitz in Schwäbisch Gmünd der Deutschen Presse-Agentur. Deshalb begrüße man den Lehrstuhl: «Es ist gut, dass Forschung und Lehre ausgebaut werden, da eine Mehrheit der Bevölkerung Komplementärmedizin wünscht und nachfragt. Es braucht Ärzte, die in diesen Bereichen auch universitär ausgebildet werden.»
Laut Koalitionsvertrag will Baden-Württemberg künftig eine Vorreiterrolle in der Erforschung der Komplementärmedizin einnehmen. Bisher gab es im Südwesten mit dem Akademischen Zentrum für Komplementäre und Integrative Medizin (AZKIM) zwar einen Verbund der Unikliniken Tübingen, Freiburg, Ulm und Heidelberg, aber keinen eigenen Lehrstuhl. Bundesweit existieren nach Angaben der Hufelandgesellschaft, dem Dachverband der Ärztegesellschaften für Naturheilkunde und Komplementärmedizin, Lehrstühle für Naturheilkunde noch an den Universitäten Duisburg-Essen, Rostock und Witten/Herdecke sowie drei Stiftungsprofessuren an der Berliner Charité.

And here is my English summary:
The black/green government of Baden-Wuerttemberg has decided to create a ‘chair of naturopathy and integrated medicine’ at the university of Tuebingen in 2019. The chair will focus in the area of oncology. Treatments such as homeopathy and anthroposophical medicine will not be taught but merely mentioned in lectures. Ideologies and everything that is not science will be omitted.
The chair will thus deal with nutrition, acupuncture and probiotics. The teaching activities will be in the medical faculty at Tuebingen, while the research will be located at the Robert-Bosch Hospital in Stuttgart. The funds for the first 5 years – 1.84 million Euro – will come from the Robert-Bosch Foundation; thereafter they will be provided by the government of the county.
So-called gentle or natural therapies cannot cure serious diseases on their own, but as adjuvant treatments they can be helful, for instance, in alleviating the adverse effects of chemotherapy. There are only few studies on this, and the new chair will increase patient safety and facilitate the reimbursement of these treatments by health insurances.
Local anthroposophy manufacturers like Wala welcomed the move stating it would be in accordance with the wishes of many patients and doctors. They also hope that the move will bring light in the current critical debate about homeopathy. A spokesperson of Weleda added that they ‘note with surprise that time-tested therapies like homeopathy are being discredited. Therefore, it is laudable that research and education in this realm will be extended. The majority of the public want complementary medicine and need doctors who are also university-trained.’
Baden-Wurttemberg aims for a leading role in researching complementary medicine. Thus far, chairs of complementary medicine existed only at the universities of Duisburg-Essen, Rostock und Witten/Herdecke as well as three professorships at the Charité in Berlin.
END OF MY SUMMARY
As I have occupied a chair of complementary medicine for 19 years, I am tempted to add a few points here.
- In principle, a new chair can be a good thing.
- The name of the chair is odd, to say the least.
- As the dean of the Tuebingen medical school pointed out, it has to be based on science. But how do they define science?
- Where exactly does the sponsor, the Robert-Bosch Stiftung, stand on alternative medicine. Do they have a track-record of being impractical and scientific?
- In order to prevent this becoming a unrealistic prospect, it is essential that the new chair needs to fall into the hands of a scientist with a proven track record of critical thinking.
- Rigorous scientist with a proven track record of critical thinking are very rare in the realm of alternative medicine.
- The ridiculous comments by Wala and Weleda, both local firms with considerable local influence, sound ominous and let me suspect that proponents of alternative medicine aim to exert their influence on the new chair.
- The above-voiced notion that the new chair is to facilitate the reimbursement of alternative treatments by the health insurances seems even more ominous. Proper research has to be objective and could, depending on its findings, have the opposite effect. To direct it in this way seems to determine its results before the research has started.
- I miss a firm commitment to medical ethics, to the principles of EBM, and to protecting the independence of the new chair.
Thus, I do harbour significant anxieties about this new chair. It is in danger of becoming a chair of promoting pseudoscience. I hope the dean of the Tuebingen medical school might read these lines.
I herewith offer him all the help I can muster in keeping pseudoscience out of this initiative, in defining the remit of the chair and, crucially, in finding the right individual for doing the job.
Homotoxicology is sometimes praised as the ‘best kept detox secret‘, often equated with homeopathy, and even more often not understood at all.
But what is it really?
Homotoxicology is the science of toxins and their removal from the human body. It offers a theory of disease which describes the severity and duration of an illness or disorder based on toxin-loading relative to our body’s ability to detoxify. In other words, it tells you how sick you’ll get when what stays inside progressively overwhelms our ability to get the garbage out. It explains what you can expect to see as you start removing toxins.
And yes, there is a hierarchy of toxic substances. Homotoxicology says you should remove the gentler ones first. As the body strengthens, it will be able to handle the really bad stuff (i.e., heavy metals). This explains why some people do really well on the same detox treatments that take others out at the knees.
Yes, I know!
This sounds very much like promotional BS!!!
So, what is it really, and what evidence is there to support it?
Homotoxicolgy is a therapy developed by the German physician and homeopath Hans Reckeweg. It is strongly inﬂuenced by (but not identical with) homoeopathy. Proponents of homotoxicology understand it as a modern extension of homoeopathy developed partly in response to the effects of the Industrial Revolution, which imposed chemical pollutants on the human body.
According to the assumptions of homotoxicology, any human disease is the result of toxins, which originate either from within the body or from its environment. Allegedly, each disease process runs through six speciﬁc phases and is the expression of the body’s attempt to cope with these toxins. Diseases are thus viewed as biologically useful defence mechanisms. Health, on the other hand, is the expression of the absence of toxins in our body. It seems obvious that these assumptions are not based on science and bear no relationship to accepted principles of toxicology or therapeutics. In other words, homotoxicology is not plausible.
The therapeutic strategies of homotoxicology are essentially threefold:
• prevention of further homotoxicological challenges,
• elimination of homotoxins,
• treatment of existing ‘homotoxicoses’.
Frequently used homotoxicological remedies are ﬁxed combinations of homeopathically prepared remedies such as nosodes, suis-organ preparations and conventional drugs. All these remedies are diluted and potentised according to the rules of homoeopathy. Proponents of homotoxicology claim that they activate what Reckeweg called the ‘greater defence system’— a concerted neurological, endocrine, immunological, metabolic and connective tissue response that can give rise to symptoms and thus excretes homotoxins. Homotoxicological remedies are produced by Heel, Germany and are sold in over 60 countries. The crucial diﬀerence between homotoxicology and homoeopathy is that the latter follows the ‘like cures like’ principle, while the former does not. As this is the defining principle of homeopathy, it would be clearly wrong to assume that homotoxicology is a form of homeopathy.
Several clinical trials of homotoxicology are available. They are usually sponsored or conducted by the manufacturer. Independent research is very rare. In most major reviews, these studies are reviewed together with trials of homeopathic remedies which is obviously not correct. Our systematic review purely of studies of homotoxicology included 7 studies, all of which had major flaws. We concluded that the placebo-controlled, randomised clinical trials of homotoxicology fail to demonstrate the efficacy of this therapeutic approach.
So, I ask again: what is homotoxicology?
It is little more than homeopathic nonsense + detox nonsense + some more nonsense.
My advice is to say well clear of it.
Often referred to as “Psychological acupressure”, the emotional freedom technique (EFT) works by releasing blockages within the energy system which are the source of emotional intensity and discomfort. These blockages in our energy system, in addition to challenging us emotionally, often lead to limiting beliefs and behaviours and an inability to live life harmoniously. Resulting symptoms are either emotional and/ or physical and include lack of confidence and self esteem, feeling stuck anxious or depressed, or the emergence of compulsive and addictive behaviours. It is also now finally widely accepted that emotional disharmony is a key factor in physical symptoms and dis-ease and for this reason these techniques are being extensively used on physical issues, including chronic illness with often astounding results. As such these techniques are being accepted more and more in medical and psychiatric circles as well as in the range of psychotherapies and healing disciplines.
An EFT treatment involves the use of fingertips rather than needles to tap on the end points of energy meridians that are situated just beneath the surface of the skin. The treatment is non-invasive and works on the ethos of making change as simple and as pain free as possible.
EFT is a common sense approach that draws its power from Eastern discoveries that have been around for over 5,000 years. In fact Albert Einstein also told us back in the 1920’s that everything (including our bodies) is composed of energy. These ideas have been largely ignored by Western Healing Practices and as they are unveiled in our current times, human process is reopening itself to the forgotten truth that everything is Energy and the potential that this offers us.

If you ask me, this sounds as though EFT combines pseudo-psychological with acupuncture-BS.
But I may be wrong.
What does the evidence tell us?
A systematic review included 14 RCTs of EFT with a total of 658 patients. The pre-post effect size for the EFT treatment group was 1.23 (95% confidence interval, 0.82-1.64; p < 0.001), whereas the effect size for combined controls was 0.41 (95% confidence interval, 0.17-0.67; p = 0.001). Emotional freedom technique treatment demonstrated a significant decrease in anxiety scores, even when accounting for the effect size of control treatment. However, there were too few data available comparing EFT to standard-of-care treatments such as cognitive behavioural therapy, and further research is needed to establish the relative efficacy of EFT to established protocols. Meta-analyses indicate large effect sizes for posttraumatic stress disorder, depression, and anxiety; however, treatment effects may be due to components EFT shares with other therapies.
Another, more recent analysis reviewed whether EFTs acupressure component was an active ingredient. Six studies of adults with diagnosed or self-identified psychological or physical symptoms were compared (n = 403), and three (n = 102) were identified. Pretest vs. posttest EFT treatment showed a large effect size, Cohen’s d = 1.28 (95% confidence interval [CI], 0.56 to 2.00) and Hedges’ g = 1.25 (95% CI, 0.54 to 1.96). Acupressure groups demonstrated moderately stronger outcomes than controls, with weighted posttreatment effect sizes of d = -0.47 (95% CI, -0.94 to 0.0) and g = -0.45 (95% CI, -0.91 to 0.0). Meta-analysis indicated that the acupressure component was an active ingredient and outcomes were not due solely to placebo, nonspecific effects of any therapy, or non-acupressure components.
From these and other reviews, one could easily get the impression that my above-mentioned suspicion is erroneous and EFT is an effective therapy. But I still do have my doubts.
These reviews conveniently forget to mention that the primary studies tend to be of poor or even very poor quality. The most common flaws include tiny sample sizes, wrong statistical approach, lack of blinding, lack of control of placebo and other nonspecific effects. Reviews of such studies thus turn out to be a confirmation of the ‘rubbish in, rubbish out’ principle: any summary of flawed studies are likely to produce a flawed result.
Until I have good quality trials to convince me otherwise, EFT is in my view:
- implausible and
- not of proven effectiveness for any condition.
