Let’s be clear: pseudoscience kills. And they are being used with total impunity thanks to European
laws that protect them.
They kill thousands of people, with names and families. People such as Francesco Bonifaz, a 7-yearold boy whose doctor prescribed homeopathy instead of antibiotics. He died in Italy . People like Mario Rodríguez, who was 21 years old and was told to use vitamins to treat his cancer. He died in Spain . People like Jacqueline Alderslade, a 55-year-old woman whose homeopath told her to stop taking her asthma medication. She died in Ireland . People like Cameron Ayres, a 6-month-old baby, whose parents did not want to give their child “scientific medicine”. He died in England . People like Victoria Waymouth, a 57-year-old woman who was prescribed a homeopathic medication to treat her heart problem. She died in France . People like Sofia Balyaykina, a 25-year-old woman, who had a cancer that was curable with chemotherapy but was recommended an “alternative treatment”, a mosquito bite treatment. She died in Russia . People like Erling Møllehave, a 71-year-old man whose acupuncturist pierced and damaged his lung with a needle. He died in Denmark . People like Michaela Jakubczyk-Eckert, a 40-year-old-woman whose therapist recommended the German NewMedicine to treat her breast cancer. She died in Germany . People like Sylvia Millecam, a 45-year-old woman whose New Age healer promised to cure her cancer. She died in the Netherlands .
European directive 2001/83/CE has made –and still makes— possible the daily deception of thousands of hundreds of European citizens . Influential lobbyists have been given the opportunity to redefine what a medicine is, and now they are selling sugar to sick people and making them believe it can cure them or improve their health. This has caused deaths and will continue to do so until Europe admits an undeniable truth: scientific knowledge cannot yield to economic interests, especially when it means deceiving patients and violating their rights.
Europe is facing very serious problems regarding public health. Overmedication, multi-resistant bacteria and the financial issues of the public systems are already grave enough, without the additional problem of gurus, fake doctors or even qualified doctors claiming they can cure any disease by manipulating chakras, making people eat sugar or using “quantic frequencies”. Europe must not only stop the promotion of homeopathy but also actively fight to eradicate public health scams. More than 150 pseudo-therapies have been identified as being in use throughout Europe. Thousands of citizens lives depend on this being prevented. In fact, according to a recent research, 25.9 % of Europeans have used pseudo-therapies last year. In other words, 192 million patients have been deceived .
Some believe there is a conflict between freedom of choice for a treatment and the removal of pseudo-therapies, but this is not true. According to article 25 of the Universal Declaration of Human Rights, every person has a right to medical care. Lying to patients in order to sell them useless products that could kill them breaks their right to correct information about their health. This way, even if a citizen has a right to refuse medical treatment when he or she is properly informed, it is also true that nobody has the right to lie to obtain profit at the expense of someone else’s life. Only in a world in which lying to a sick person would be considered ethical, could homeopathy —or any other pseudo-therapy— be allowed to continue to be sold to citizens.
Effective treatments being replaced by false ones is not the only danger of pseudo-therapies. Obvious delays in therapeutic care occur when a person gets false products instead of medication at the early stages of a disease. Many times, it is then too late by the time they get treated with proper medicine. Moreover, several of these practices have serious effects on their own and may cause damage or even death because of their side effects.
Many pseudo-therapists argue that “the other medicine” comes with side effects as well, which is indeed true. However, the difference resides in that pseudo-therapies cannot cure a disease or improve your health, and because of that patients assume risks in exchange of promises that are a scam, according to the full weight of the scientific evidence available. Lying to a sick person is not another type of medicine, it is simply lying to a sick person.
Every country has to face the pseudo-therapies issue in its own ways. Yet it is not acceptable that European laws protect the distortion of scientific facts so that thousands of citizens can be deceived or even lead to their deaths.
We, the signatories of this manifest, therefore declare that:
1. Scientific knowledge is incompatible with what pseudo-therapies postulate, as in the case
2. European laws that protect homeopathy are not acceptable in a scientific and technological
society that respects the right of the patients not to be deceived.
3. Homeopathy is the best known pseudo-therapy, but it is not the only one nor the most
dangerous one. Others, such as acupuncture, reiki, German New Medicine, iridology,
biomagnetism, orthomolecular therapy and many more, are gaining ground and causing
4. Measures must be taken to stop pseudo-therapies, since they are harmful and result in
thousands of people being adversely affected.
5. Europe needs to work towards creating legislation that will help stop this problem.
Europe being concerned about the misinformation phenomena but at the same time protecting one the most dangerous types of it, health misinformation, is just not coherent. This is why the people signing this manifesto urge the governments of European countries to end a problem in which the name of science is being used falsely and which has already cost too many lives.

This recent Cochrane review assessed the effects of so-called alternative medicine (SCAM) for post-caesarean pain. Randomised clinical trials (RCTs), including quasi-RCTs and cluster-RCTs, comparing SCAM, alone or associated with other forms of pain relief, versus other treatments or placebo or no treatment, for the treatment of post-CS pain were included.
A total of 37 studies (3076 women) investigating 8 different SCAM therapies for post-CS pain relief were found. There was substantial heterogeneity among the trials. The primary outcome measures were pain and adverse effects. Secondary outcome measures included vital signs, rescue analgesic requirement at 6 weeks after discharge; all of which were poorly reported or not reported at all.
The quality of the RCTs was low. Whether acupuncture or acupressure (versus no treatment) or acupuncture or acupressure plus analgesia (versus placebo plus analgesia) have any effect on pain. Acupuncture or acupressure plus analgesia (versus analgesia) may reduce pain at 12 hours (standardised mean difference (SMD) -0.28, 95% confidence interval (CI) -0.64 to 0.07; 130 women; 2 studies; low-certainty evidence) and 24 hours (SMD -0.63, 95% CI -0.99 to -0.26; 2 studies; 130 women; low-certainty evidence). It is uncertain whether acupuncture or acupressure (versus no treatment) or acupuncture or acupressure plus analgesia (versus analgesia) have any effect on the risk of adverse effects.
Aromatherapy plus analgesia may reduce pain when compared with placebo plus analgesia at 12 hours (mean difference (MD) -2.63 visual analogue scale (VAS), 95% CI -3.48 to -1.77; 3 studies; 360 women; low-certainty evidence) and 24 hours (MD -3.38 VAS, 95% CI -3.85 to -2.91; 1 study; 200 women; low-certainty evidence). The authors were uncertain whether aromatherapy plus analgesia has any effect on adverse effects (anxiety) compared with placebo plus analgesia.
Electromagnetic therapy may reduce pain compared with placebo plus analgesia at 12 hours (MD -8.00, 95% CI -11.65 to -4.35; 1 study; 72 women; low-certainty evidence) and 24 hours (MD -13.00 VAS, 95% CI -17.13 to -8.87; 1 study; 72 women; low-certainty evidence).
There were 6 RCTs (651 women), 5 of which were quasi-RCTs, comparing massage (foot and hand) plus analgesia versus analgesia. All the evidence relating to pain, adverse effects (anxiety), vital signs and rescue analgesic requirement was very low-certainty.
Music therapy plus analgesia may reduce pain when compared with placebo plus analgesia at one hour (SMD -0.84, 95% CI -1.23 to -0.46; participants = 115; studies = 2; I2 = 0%; low-certainty evidence), 24 hours (MD -1.79, 95% CI -2.67 to -0.91; 1 study; 38 women; low-certainty evidence), and also when compared with analgesia at one hour (MD -2.11, 95% CI -3.11 to -1.10; 1 study; 38 women; low-certainty evidence) and at 24 hours (MD -2.69, 95% CI -3.67 to -1.70; 1 study; 38 women; low-certainty evidence). It is uncertain whether music therapy plus analgesia has any effect on adverse effects (anxiety), when compared with placebo plus analgesia because the quality of evidence is very low.
The investigators were uncertain whether Reiki plus analgesia compared with analgesia alone has any effect on pain, adverse effects, vital signs or rescue analgesic requirement because the quality of evidence is very low (one study, 90 women). Relaxation Relaxation may reduce pain compared with standard care at 24 hours (MD -0.53 VAS, 95% CI -1.05 to -0.01; 1 study; 60 women; low-certainty evidence).
Transcutaneous electrical nerve stimulation (TENS)
TENS (versus no treatment) may reduce pain at one hour (MD -2.26, 95% CI -3.35 to -1.17; 1 study; 40 women; low-certainty evidence). TENS plus analgesia (versus placebo plus analgesia) may reduce pain compared with placebo plus analgesia at one hour (SMD -1.10 VAS, 95% CI -1.37 to -0.82; 3 studies; 238 women; low-certainty evidence) and at 24 hours (MD -0.70 VAS, 95% CI -0.87 to -0.53; 108 women; 1 study; low-certainty evidence). TENS plus analgesia (versus placebo plus analgesia) may reduce heart rate (MD -7.00 bpm, 95% CI -7.63 to -6.37; 108 women; 1 study; low-certainty evidence) and respiratory rate (MD -1.10 brpm, 95% CI -1.26 to -0.94; 108 women; 1 study; low-certainty evidence). The authors were uncertain whether TENS plus analgesia (versus analgesia) has any effect on pain at six hours or 24 hours, or vital signs because the quality of evidence is very low (two studies, 92 women).
The authors concluded that some SCAM therapies may help reduce post-CS pain for up to 24 hours. The evidence on adverse events is too uncertain to make any judgements on safety and we have no evidence about the longer-term effects on pain. Since pain control is the most relevant outcome for post-CS women and their clinicians, it is important that future studies of SCAM for post-CS pain measure pain as a primary outcome, preferably as the proportion of participants with at least moderate (30%) or substantial (50%) pain relief. Measuring pain as a dichotomous variable would improve the certainty of evidence and it is easy to understand for non-specialists. Future trials also need to be large enough to detect effects on clinical outcomes; measure other important outcomes as listed in this review, and use validated scales.
I feel that the Cochrane Collaboration does itself no favours by publishing such poor reviews. This one is both poorly conceived and badly reported. In fact, I see little reason to deal with pain after CS differently than with post-operative pain in general. Some of the modalities discussed are not truly SCAM. Most of the secondary endpoints are irrelevant. The inclusion of adverse effects as a primary endpoint seems nonsensical considering that SCAM studies are notoriously bad at reporting them. Many of the allegedly positive findings rely on trial designs that cannot control for placebo effects (e.g A+B versus B); therefore they tell us nothing about the effectiveness of the therapy.
Most importantly, the conclusions are not helpful. I would have simply stated that none of the SCAM modalities are supported by convincing evidence as treatments for pain control after CS.
This study assessed the patterns of dietary supplement usage among cancer survivors in the United States in a population-based setting. National Health and Nutrition Examination Survey (NHANES) datasets (1999-2016) were accessed, and adult respondents (≥ 20 years old) with a known status of cancer diagnosis and a known status of dietary supplements intake were included. Multivariable logistic regression analysis was then used to assess factors associated with dietary supplements intake. Moreover, and to evaluate the impact of dietary supplements on overall survival among respondents with cancer, multivariable Cox regression analysis was conducted.
A total of 49,387 respondents were included in the current analysis, including a total of 4,575 respondents with cancer. Among respondents with cancer, 3,024 (66.1%) respondents reported the use of dietary supplements; while 1,551 (33.9%) did not report the use of dietary supplements. Using multivariable logistic regression analysis, factors associated with the use of dietary supplements included:
- older age (OR: 1.028; 95% CI: 1.027-1.030);
- white race (OR for black race vs. white race: 0.67; 95% CI: 0.63-0.72);
- female gender (OR for males vs. females: 0.56; 95% CI: 0.53-0.59),
- higher income (OR: 1.13; 95% CI: 1.11-1.14),
- higher educational level (0.59; 95% CI: 0.56-0.63),
- better self-reported health (OR: 1.36; 95% CI: 1.17-1.58),
- health insurance (OR: 1.35; 95% CI: 1.27-1.44),
- history of cancer (OR: 1.20; 95% CI: 1.10-1.31).
Using multivariable Cox regression analysis and within the subgroup of respondents with a history of cancer, the use of dietary supplements was not found to be associated with a difference in overall survival (HR: 1.13; 95% CI: 0.98-1.30).
The authors concluded that dietary supplement use has increased in the past two decades among individuals with cancer in the United States, and this increase seems to be driven mainly by an increase in the use of vitamins. The use of dietary supplements was not associated with any improvement in overall survival for respondents with cancer in the current study cohort.
Many cancer patients, when they first get diagnosed, are tested for vitamin D levels and found to be low or borderline. Consequently, they get a prescription for supplements. Other than this, there is rarely an indication to take any vitamins or other dietary supplements. Yet, cancer patients take them because they think these ‘natural’ preparations can do no harm (and because the industry can be persuasive [there is big money at stake] and the odd breed of ‘integrated’ oncologists might even recommend them). Sadly, this assumption is not correct. The biggest danger, in my view, is the possibility of supplements to interact with one of the many drugs that cancer patients need to take. So, in a way, it is reassuring that, on average, there is no detrimental effect on overall survival.
The paper will probably also reignite the perennial discussion about the effects of vitamin C on the natural history of cancer. My understanding is that there is none (and this verdict seems to be supported by the findings reported here). But I am, of course, aware that this is a ‘hot potato’ and that some readers will think differently. To them I say: please show me the evidence.
Black salve is a paste for external use made from a variable mixture of herbal and non-herbal ingredients. It usually contains bloodroot and/or chaparral and/or zinc chloride which are all ingredients that render the products corrosive. This means black salve destroys living cells that come in contact with it.
Black salve is said to originate from native American tribes who used the paste as a treatment for various conditions. It was adopted by conventional medicine during the Victorian era as a treatment for a range of skin problems, including skin cancers. When effective treatments became available, it became obsolete.
Black salve was recently re-discovered by some practitioners of so-called alternative medicine (SCAM) who now recommend it as a natural treatment for various skin conditions, including cancer. Black salve is readily available, for instance, via the Internet. Several national regulators have issued warnings to consumers not to use it. Consumers have little means of telling what is the nature, quality or strength of the black salve they might be purchasing.
No compelling evidence exists that black salve is efficacious for any condition, especially not for any type of skin cancer. Rigorous clinical trials testing its efficacy are not available. A recent review of the published evidence concluded as follows: Black salve is not a natural therapy. It contains significant concentrations of synthetic chemicals. Black salve does not appear to possess tumour specificity with in vitro and in vivo evidence indicating normal cell toxicity. Black salve does appear to cure some skin cancers, although the cure rate for this therapy is currently unknown. The use of black salve should be restricted to clinical research in low risk malignancies located at low risk sites until a better understanding of its efficacy and toxicity is developed. Where a therapy capable of harm is already being used by patients, it is ethically irresponsible not to study and analyse its effects. Although cautionary tales are valuable, black salve research needs to move beyond the case study and into the carefully designed clinical trial arena. Only then can patients be properly informed of its true benefits and hazards.
Due to its erosive nature, black salve burns away the tissue with which it comes into contact. Numerous case reports of the resulting deformations have been published., Many horrendous pictures of patients maimed by their use of black salve are available on the Internet and give a dramatic impression of the harm caused. Black salve is unquestionably a treatment that can cause considerable damage and should be regarded as unsafe. One paper concluded that it is vital that members of the public are aware of the potential effects and toxicity of commercial salve products.
In conclusion, black salve is not of proven efficacy as a treatment of any condition. It is well documented to cause much harm. Its use should be discouraged. Practitioners who employ or recommend it are, in my view, irresponsible to the extreme.

Guest post by Ken McLeod
‘Ayurvedic Medicine,’ or Ayurveda, is an alternative medicine system which originated in India as long as 5,000 years ago, according to its proponents. Science-based medicine refers to it as pseudoscientific and the Indian Medical Association (IMA) characterises it as quackery.  Ayurvedic practitioners claim that its popularity through the ages vindicates it as safe and effective.
That last bit is of course the appeal to antiquity, or the appeal to tradition (also known as argumentum ad antiquitatem.  This proposes that if something was supported by people for a long time it must be valid. That is bunkum; many ancient ideas have long since been discredited; the Earth is not flat, no matter for how long people thought it was.
Nevertheless, ‘Ayurvedic Medicine’ has many practitioners and supporters in the supposedly rational West, including Bondi Junction here in Australia. Despite the many warnings about it,  people still go to practitioners, and occasionally they are injured.
One such injury and the consequent complaint to the New South Wales regulator, the Health Care Complaints Commission, (HCCC), has resulted in a Public Warning dated 18 September concerning levels of heavy metals in Ayurvedic Medication. 
The HCCC said:
‘The NSW Health Care Complaints Commission is concerned about a complaint received regarding the prescription of “Manasamithra Vatika,” (Manasamitram Pills) an Ayurvedic medication.
‘The complaint related to prescription of this medication to a child for treatment of autism.
‘This medication was found to contain concerning levels of lead and other heavy metals.’
That’s all very bland, no headlines there. But then it got into:
“The Commission strongly urges those individuals seeking alternative therapies to be vigilant in their research prior to proceeding with any natural therapy medications or medicines and to discuss any such proposed therapies with their treating registered health practitioner.”
Not so bland there; that’s very comprehensive; ‘any natural therapy medications or medicines’ and ‘discuss any such proposed therapies with their treating registered health practitioner.” ‘Note the HCCC’s emphasis on “registered.” That rules out Ayurvedic Medicine practitioners, homeopaths, and other assorted cranks; go to a real doctor.
Surely that is headline material; a regulator responsible for promoting the health of citizens warns them to go to real doctors before going to these quacks.
Then it gets better, (or worse if you are an Ayurvedic Medicine practitioner). At the same time the HCCC issued an Interim Prohibition Order against Mr Rama Prasad (“Ayurveda Doctor Rama Prasad.”)  The HCCC’s Order says:
‘The NSW Health Care Complaints Commission (“the Commission”) is currently investigating Mr Rama Prasad in relation to his prescribing of the Ayurvedic Medication “Manasamithra Vatika” (Manasamitram Pills) to both children and adults and about his claims that his treatments can reverse several aspects of autism in children.
‘The Ayurvedic Medication “Manasmithra Vatika” (Manasamitram Pills) was found to contain elevated levels of lead and other heavy metals.
‘One case with mildly elevated blood level was notified to the South Eastern Sydney Public Health Unit after consuming this product.
‘Clients residing in NSW who are considered to have been placed at possible risk have now been contacted by NSW Health public health personnel.
‘The Commission has issued an interim prohibition order in relation to Mr Rama Prasad, under section 41AA of the Health Care Complaints Act 1993 (‘The Act’). Mr Prasad is currently prohibited from providing any health services, either in paid employment or voluntarily, to any member of the public.
‘This interim prohibition order will remain in force for a period of eight weeks and may be renewed where appropriate in order to protect the health or safety of the public.’
That should send chills down the spine of any Ayurvedic Medicine practitioner. A complete Prohibition Order ordering Prasad not to engage in providing any health service as defined in the Act  for eight weeks, which may be renewed or even made permanent, depending on what the investigation finds. The Act includes a comprehensive list of activities that comprise a ‘health service’:
‘health service includes the following services, whether provided as public or private services:
- (a) medical, hospital, nursing and midwifery services,
- (b) dental services,
- (c) mental health services,
- (d) pharmaceutical services,
- (e) ambulance services,
- (f) community health services,
- (g) health education services,
- (h) welfare services necessary to implement any services referred to in paragraphs (a)–(g),
- (i) services provided in connection with Aboriginal and Torres Strait Islander health practices and medical radiation practices,
- (j) Chinese medicine, chiropractic, occupational therapy, optometry, osteopathy, physiotherapy, podiatry and psychology services,
- (j1) optical dispensing, dietitian, massage therapy, naturopathy, acupuncture, speech therapy, audiology and audiometry services,
- (k) services provided in other alternative health care fields,
- (k1) forensic pathology services,’
Note the inclusion of ‘health education.’ This is where so many cranks fall foul of the law; setting yourself up as a health educator makes you subject to the Act. Even if you claim to be a master chef, homeopath or Ayurvedic Medicine Practitioner, you are not exempt.
It’s early days yet in this particular saga, and there are many questions to be answered, for example:
- – How did this “medicine” get past Australia’s Therapeutic Goods Administration, (Australia’s equivalent to the US FDA)?
- – Did the TGA list or register it?
- – If not why not? If it was who is responsible?
- – Was this detected only after a child was so sickened that they were taken to hospital?
- – Why is the practitioner concerned still advertising his Ayurvedic medicine courses?  Is this a breach of his Prohibition Order which prohibits ‘health education services’?’
So stay tuned for updates as this case progresses. In the meantime note that an Australian Health regulator is advising the public to seek advice from real doctors before going to alternative therapists, including ‘Ayurvedic Medicine’ practitioners. That is a real headline.

‘Infodemics’ are outbreaks of false information including rumours, stigma, and conspiracy theories. All of these have been common during the COVID-19 pandemic. The detection, assessment, and response to rumours, stigma, and conspiracy theories in real time are a challenge.
An international team of researchers followed and examined COVID-19-related rumours, stigma, and conspiracy theories circulating on online platforms, including fact-checking agency websites, Facebook, Twitter, and online newspapers, and their impacts on public health. Information was extracted between December 31, 2019 and April 5, 2020, and descriptively analysed. The team performed a content analysis of the news articles to compare and contrast data collected from other sources.
The researchers identified 2,311 reports of rumours, stigma, and conspiracy theories in 25 languages from 87 countries. Claims were related to:
- illness, transmission and mortality (24%),
- control measures (21%),
- treatment and cure (19%),
- cause of disease including the origin (15%),
- violence (1%),
- and miscellaneous (20%).
Of the 2,276 reports for which text ratings were available, 1,856 claims were false (82%).
The authors concluded that misinformation fuelled by rumours, stigma, and conspiracy theories can have potentially serious implications on the individual and community if prioritized over evidence-based guidelines. Health agencies must track misinformation associated with the COVID-19 in real time, and engage local communities and government stakeholders to debunk misinformation.
These findings are as perplexing as they are frightening. On this blog, we have since the beginning of the pandemic focussed on the SCAM for COVID-19. We have seen that this health crisis provided an occasion for almost any quackery on the planet:
- supplement salesmen,
- essential oil salesmen.
They all crept out of the woodwork. Their methods may differ, but their aim seems to be the same: to make a fast buck regardless of how many people their activities might kill.
The ketogenic diet (KD) is a currently popular high-fat, low-carbohydrate diet; it limits the intake of glucose which results in the production of ketones by the liver and their uptake as an alternative energy source by the brain. KD is an effective treatment for intractable epilepsy. In addition, it is being promoted as a so-called alternative medicine (SCAM) for a wide range of conditions, including:
- weight loss,
- cognitive and memory enhancement,
- type II diabetes,
- neurological and psychiatric disorders.
However, these indications are not supported by good evidence.
A side effect of KD is “keto flu,” a syndrome of transient symptoms generally reported as occurring within the first few weeks of adhering to the diet. These symptoms can feel similar to the flu and are caused by the body adapting to a new diet consisting of very little carbohydrates.
Ketones are by-products of fat breakdown and become the main energy source when following the KD. Normally, fat is reserved as a secondary fuel source to use when glucose is not available. This switch to burning fat for energy is called ketosis. It occurs during specific circumstances, including starvation, fasting … or KD. The KD reduces carbohydrates typically to under 50 grams per day. This drastic reduction may cause withdrawal-like symptoms, similar to those experienced when weaning off an addictive substance.
A recent paper aimed to characterize the pattern of symptoms, severity and time course of keto flu as related by users of online forums. Online forums referring to “keto flu,” “keto-induction,” or “keto-adaptation” in the URL were identified. Passages describing personal experiences of keto flu were categorized with reference to pattern of symptoms, severity, time course, and remedies proposed.
The search criteria identified 75 online forums, 43 met inclusion criteria and contained 448 posts from 300 unique users. Seventy-three made more than one post (mean 3.12, range 2-11). Descriptors of personal experience of keto flu, reported by 101 of 300 users, included 256 symptom descriptions involving 54 discrete symptoms. Commonest symptoms were “flu,” headache, fatigue, nausea, dizziness, “brain fog,” gastrointestinal discomfort, decreased energy, feeling faint and heartbeat alterations.
Symptom reports peaked in the first and dwindled after 4 weeks. Resolution of keto flu symptoms was reported by 8 users between days 3 and 30 (median 4.5 ). Severity of symptoms, reported by 60 users in 40 forums, was categorized as mild (N = 15), moderate (N = 23), or severe (N = 22). Eighteen remedies were proposed by 121 individual users in 225 posts. The following treatments were most frequently recommended (numbers represent the number of times of each recommendation was made):
|Increase sodium intake||58|
|Supplement with electrolytes||38|
|Drink broth (including bone broth, stock cubes)||27|
I find this paper interesting, not least because of the unusual methodological approach. It seems to confirm that, even though the KD is often recommended as safe, it is associated with significant side-effects. One adverse effect remained unmentioned, while leading to more people discontinuing the diet than any other side-effect: the fact that the diet is quite unpalatable on the long-run and soon puts people off eating. This, of course, might be one mechanism by which KD leads to weight loss.
On this blog, I have discussed the adverse events (AEs) of spinal manipulative therapy (SMT) with some regularity, and we have seen that ~ 50% of patients who receive SMT from a chiropractor experience some kind of AE. In addition there are many serious complications. In my book, I discuss, apart from the better-known vascular accidents followed by a stroke or death, the following:
- atlantoaxial dislocation,
- cauda equina syndrome,
- cervical radiculopathy,
- diaphragmatic paralysis,
- disrupted fracture healing,
- dural sleeve injury,
- haemorrhagic cysts,
- muscle abscess,
- muscle abscess,
- neurologic compromise,
- oesophageal rupture
- soft tissue trauma,
- spinal cord injury,
- vertebral disc herniation,
- vertebral fracture,
- central retinal artery occlusion,
- Wallenberg syndrome,
- loss of vision,
- Horner’s syndrome.
Considering this long list, we currently have far too little reliable information. A recent publication offers further information on this important topic.
The aim of this study was to identify beliefs, perceptions and practices of chiropractors and patients regarding benign AEs post-SMT and potential strategies to mitigate them. Clinicians and patients from two chiropractic teaching clinics were invited to respond to an 11-question survey exploring their beliefs, perceptions and practices regarding benign AEs post-SMT and strategies to mitigate them.
A total of 39 clinicians (67% response rate) and 203 patients (82.9% response rate) completed the survey. The results show that:
- 97% of the chiropractors believed benign AEs occur.
- 82% reported their own patients have experienced an AE.
- 55% of the patients reported experiencing benign AEs post-SMT, with the most common symptoms being pain/soreness, headache and stiffness.
- 61.5% of the chiropractors reported trying a mitigation strategy with their patients.
- Yet only 21.2% of patients perceived their clinicians had tried any mitigation strategy.
- Chiropractors perceived that patient education is most likely to mitigate benign AEs, followed by soft tissue therapy and/or icing after SMT.
- Patients perceived stretching was most likely to mitigate benign AEs, followed by education and/or massage
The authors concluded that this is the first study comparing beliefs, perceptions and practices from clinicians and patients regarding benign AEs post-SMT and strategies to mitigate them. This study provides an important step towards identifying the best strategies to improve patient safety and improve quality of care.
The question that I have often asked before, and I am bound to ask again after seeing such results, is this:
If there were a drug that causes temporary pain/soreness, headache and stiffness in 55% of all patients (plus an unknown frequency of a long list of serious complications), while being of uncertain benefit, do you think it would still be on the market?
Yes, I know what you will say: homeopathic remedies are all nothing but diluted water. But the ‘diluted water’ remedies that this post is about are different. Even their starting material – homeopaths call it mother tincture – is nothing but water. And what is more, homeopaths are so fond of these ‘diluted water’ remedies that they have more than one of it! One might think that water is water, especially, if you dilute it endlessly with pure distilled water. This may be true for most of us, but not for homeopaths – FAR FROM IT!
Here I present you those commercially available ‘diluted water’ remedies that I have found (I am fairly sure there are more, if you search more thoroughly than I did):
- Aqua Aurum (Gold and sea water)
- Aqua Fida Vetusta (Old Faithful Water)
- Aqua Hochstein (Spring Source water from the Bavarian Forest)
- Aqua marina (Sea Water)
- Aqua nova
- Aqua Odilien
- Aqua Pura Bottled Water
- Aqua Schuasta
- Aqua Sulis (Water from Bath, Roman Spa)
- Aqua Victoria Falls
- Aqua XwMuthkwium (Musqueam Creek Water)
- Chalice Well Water
- Dead Sea Water
- Double Helix Water
- Ganga water (water from the River Ganges)
- Ganga Water (Gaumuk)
- Ganga Water (Varanasi)
- Gastein (Gastein Aqua)
- Geum Rivale (Water Avens)
- Halltal Spring Water (Water from Solbadhall in Tirol)
- Levico water (from lake in N Italy)
- Lourdes Water
- Nadana Water
- Nigari (Concentrated Japanese seawater)
- Nordenau water
- Seven Spring Head Water
- Severn Water (Source)
- Water (Guild)
- Wiesbaden Aqua (Wiesbaden Water)
- Winchelsea Water
- Zamzam aqua (Zamzam spring water [Mecca])
I don’t know about you, but I was impressed to find this big a variety of water – better than in a three-star restaurant! My favourite is not the water from my place of birth, Wiesbaden, but LORDES WATER. I am sure you will ask me what all these waters are used for. Lourdes water is the only water remedy for which we can tell with any degree of certainty:
- The original Lourdes water is supposed to heal patients of all ills.
- Now, please apply the ‘like cures like’ hypothesis of homeopathy to this fact.
- The result is clear: homeopathic Lourdes water is supposed to give you all diseases known to mankind.
And then some nutters try to tell you that homeopathy is not dangerous!!!
This Cochrane review assessed the efficacy and safety of aromatherapy for people with dementia. The researchers included randomised controlled trials which compared fragrance from plants in an intervention defined as aromatherapy for people with dementia with placebo aromatherapy or with treatment as usual. All doses, frequencies and fragrances of aromatherapy were considered. Participants in the included studies had a diagnosis of dementia of any subtype and severity.
The investigators included 13 studies with 708 participants. All participants had dementia and in the 12 trials which described the setting, all were resident in institutional care facilities. Nine trials recruited participants because they had significant agitation or other behavioural and psychological symptoms in dementia (BPSD) at baseline. The fragrances used were:
- lavender (eight studies);
- lemon balm (four studies);
- lavender and lemon balm,
- lavender and orange,
- cedar extracts (one study each).
For six trials, assessment of risk of bias and extraction of results was hampered by poor reporting. Four of the other seven trials were at low risk of bias in all domains, but all were small (range 18 to 186 participants; median 66). The primary outcomes were:
- overall behavioural,
- psychological symptoms,
- adverse effects.
Ten trials assessed agitation using various scales. Among the 5 trials for which the confidence in the results was moderate or low, 4 trials reported no significant effect on agitation and one trial reported a significant benefit of aromatherapy. The other 5 trials either reported no useable data or the confidence in the results was very low. Eight trials assessed overall BPSD using the Neuropsychiatric Inventory and there was moderate or low confidence in the results of 5 of them. Of these, 4 reported significant benefit from aromatherapy and one reported no significant effect.
Adverse events were poorly reported or not reported at all in most trials. No more than two trials assessed each of our secondary outcomes of quality of life, mood, sleep, activities of daily living, caregiver burden. There was no evidence of benefit on these outcomes. Three trials assessed cognition: one did not report any data and the other two trials reported no significant effect of aromatherapy on cognition. The confidence in the results of these studies was low.
The authors reached the following conclusions: We have not found any convincing evidence that aromatherapy (or exposure to fragrant plant oils) is beneficial for people with dementia although there are many limitations to the data. Conduct or reporting problems in half of the included studies meant that they could not contribute to the conclusions. Results from the other studies were inconsistent. Harms were very poorly reported in the included studies. In order for clear conclusions to be drawn, better design and reporting and consistency of outcome measurement in future trials would be needed.
This is a thorough review. It makes many of the points that I so often make regarding SCAM research:
- too many of the primary studies are badly designed;
- too many of the primary studies are too small;
- too many of the primary studies are poorly reported;
- too many of the primary studies fail to mention adverse effects thus violating research ethics;
- too many of the primary studies are done by pseudo-scientists who use research for promotion rather than testing hypotheses.
It is time that SCAM researchers, ethic review boards, funders, editors and journal reviewers take these points into serious consideration – if only to avoid clinical research getting a bad reputation and losing the support of patients without which it cannot exist.
