Many hundreds of plants worldwide have a place in folk medicine as treatments for microbial infections and antimicrobial activity of extracts in vitro may be readily assessed in microbiology laboratories. Many so tested are reported to show inhibitory effects against a range of organisms. For less than responsible entrepreneurs, this is often enough reason to promote them as therapeutic options.
But laboratory testing can at best be only a very crude, though relatively inexpensive and rapid screen, while in vivo testing is very costly and time consuming. On this background, we conducted a review in 2003 to examine the range of plants or herbs that have been tested for antiviral properties in laboratories, animals and humans. Here is its abstract:
Background and aims: Many antiviral compounds presently in clinical use have a narrow spectrum of activity, limited therapeutic usefulness and variable toxicity. There is also an emerging problem of resistant viral strains. This study was undertaken to examine the published literature on herbs and plants with antiviral activity, their laboratory evaluation in vitro and in vivo, and evidence of human clinical efficacy.
Methods: Independent literature searches were performed on MEDLINE, EMBASE, CISCOM, AMED and Cochrane Library for information on plants and herbs with antiviral activity. There was no restriction on the language of publication. Data from clinical trials of single herb preparations used to treat uncomplicated viral infections were extracted in a standardized, predefined manner.
Results: Many hundreds of herbal preparations with antiviral activity were identified and the results of one search presented as an example. Yet extracts from only 11 species met the inclusion criteria of this review and have been tested in clinical trials. They have been used in a total of 33 randomised, and a further eight non-randomised, clinical trials. Fourteen of these trials described the use of Phyllanthus spp. for treatment of hepatitis B, seven reporting positive and seven reporting negative results. The other 10 herbal medicines had each been tested in between one and nine clinical trials. Only four of these 26 trials reported no benefit from the herbal product.
Conclusions: Though most of the clinical trials located reported some benefits from use of antiviral herbal medicines, negative trials may not be published at all. There remains a need for larger, stringently designed, randomised clinical trials to provide conclusive evidence of their efficacy.
One of the herbal remedies that seemed to show some promise specifically for upper respiratory infections was Andrographis paniculata. This evidence prompted us in 2004 to conduct a systematic review focused on this herb specifically. Here is its abstract:
Acute respiratory infections represent a significant cause of over-prescription of antibiotics and are one of the major reasons for absence from work. The leaves of Andrographis paniculata (Burm. f.) Wall ex Nees (Acanthaceae) are used as a medicinal herb in the treatment of infectious diseases. Systematic literature searches were conducted in six computerised databases and the reference lists of all papers located were checked for further relevant publications. Information was also requested from manufacturers, the spontaneous reporting schemes of the World Health Organisation and national drug safety bodies. No language restrictions were imposed. Seven double-blind, controlled trials (n = 896) met the inclusion criteria for evaluation of efficacy. All trials scored at least three, out of a maximum of five, for methodological quality on the Jadad scale. Collectively, the data suggest that A. paniculata is superior to placebo in alleviating the subjective symptoms of uncomplicated upper respiratory tract infection. There is also preliminary evidence of a preventative effect. Adverse events reported following administration of A. paniculata were generally mild and infrequent. There were few spontaneous reports of adverse events. A. paniculata may be a safe and efficacious treatment for the relief of symptoms of uncomplicated upper respiratory tract infection; more research is warranted.
Before you now rush to buy a dietary supplement of A. paniculata, let me stress this in no uncertain terms: the collective evidence is at best suggestive, but it is not compelling. Importantly, there is, to the best of my knowledge, no sound evidence that any herbal remedy is effective in preventing or treating Covid-19 infections.
I truly wished to be able to report more encouraging news, but the truth is the truth, even (I would argue, particularly) in desperate times.
The ‘Corona-Virus Quackery Club’ (CVQC) is getting positively crowded. You may remember, its members include:
- colloidal silver crooks,
- TCM practitioners,
- orthomolecular quacks,
- essential oil salesmen,
- and urine/dung peddlers.
Today we are admitting the herbalists. The reason is obvious: many of them have jumped on the corona band-wagon by trying to improve their cash-flow on the back of the pandemic-related anxiety of consumers. If you go on the Internet you will find many examples, I am sure. I have chosen this website for explaining the situation.
Herbs That Can Stop Coronavirus Reproduction
CoV multiplies fast in the lungs and the stomach and intestines. The more virus, the sicker you get. The herbs are in their scientific names and common names.
- Cibotium barometz – golden chicken fern or woolly fern grows in China and Southeast Asia.
- Gentiana scabra – known as Korean gentian or Japanese gentian seen in the United States and Japan.
- Dioscorea batatas or Chinese Yam grows in China and East Asia
- Cassia tora or Foetid cassia, The Sickle Senna, Wild Senna – grows in India and Central America
- Taxillus Chinensis – Mulberry Mistletoe
- Cibotium barometz – golden chicken fern or woolly fern grows in China and Southeast Asia.
Lectin Plants that Have Anti Coronavirus Properties
From the table above, all have anti coronavirus activity except for garlic. One plant that is effective but not listed is Stinging nettle.
Yes, very nice pictures – but sadly utterly unreliable messages. My advice is that, in case you have concerns about corona (or any other health problem for that matter), please do not ask a herbalist.
WELCOME TO THE CVQC, HERBALISTS!
Lynne McTaggart and Bryan Hubbard, editors of What Doctors Don’t Tell You and Get Well magazines, are pleased to announce a series of four FREE weekly webinars, via Zoom, starting Thursday, April 2 designed to maximize your health and wellness in every way during these challenging times.
In these free hour-long sessions, Lynne and Bryan will interview a number of pioneering doctors and specialists, who will give you detailed advice about natural substances that kill viruses, the best supplements, foods and exercises to boost your immune system, and the best techniques to stay calm and centered during these challenging times.
Sign up to be sent the link for the live webinar where you can have the ability to ask your questions to these pioneers, get access to the recording of the webinars and receive a handout of helpful relevant tips to that webinar.
Thursday, April 2, 2020
9 am PDST/12pm EDST/5 pm BST/6 pm CSTThis webinar will feature the best substances and supplements proven to prevent the spread of viruses. Joining Lynne and Bryan are noted pioneer Dr. Damien Downing, president of the Society for Environmental Medicine, who was part of a team of orthomolecular doctors who devised a special supplement preventative against the coronavirus; Dr. Sarah Myhill, a British integrative doctor noted expert on vitamin C and other natural virus killers; and Dr. Robert Verkerk PhD, the founder and president of the Alliance for Natural Health and an expert on food and health.
So far, our ‘Corona-Virus Quackery Club’ (CVQC) boasts the following membership:
- colloidal silver crooks,
- TCM practitioners,
- orthomolecular quacks,
- essential oil salesmen,
- and the urine/dung quacks.
It is time now, I think, to admit some supplement peddlers.
Many dietary supplement merchants seem to feel that the current pandemic is an excellent opportunity to flog their useless wares to the anxious public.
In order to support increasing worldwide demand for the LYMA supplement, we would like to inform new and existing customers that we have sufficient stock in place to ensure uninterrupted supply.”
This was the text of an email I received recently. It linked to a website that informed me of the following:
We continue to work with our scientific network and global supply chain to bring you the latest scientific developments as they arise.
Dr. Paul Clayton, PhD – Director of Science, LYMA
“Covid-19 is causing an enormous amount of illness and disruption. This is due to its high transmission rates, long incubation period, and the substantial numbers of people – 15 to 20% of those infected – who become ill enough to require hospitalisation. This last aspect is concerning as no health care system in the world has sufficient resources to cope with such an influx of seriously ill patients.
At the time of writing there are no specific treatments available. The only advice given is to avoid crowds, wash the hands frequently, and not touch the face. Some authorities recommend face masks and gloves; and we are increasingly being recommended to shelter in place.
But there may be more we can do to protect ourselves. Dysnutrition is common, due to our over-consumption of ultra-processed foods with little nutritional value. Supplements have a role to play in improving general nutritional status and general immunity. But we can take that further.
LYMA. The ultimate supplement.
Chronic stress reduces immuno-competence and makes us more vulnerable to infection. Adaptogens such as KSM-66 Ashwagandha in LYMA have the ability to alleviate the damaging effects of stress and have been shown to improve immunity. So have the Wellmune 1-3, 1-6 beta glucans in LYMA, with many hundreds of studies showing that these natural compounds increase resistance to infection.
These are just two elements that may improve our chances in the difficult times ahead.”
Dr. Paul Clayton, PhD – Director of Science, LYMA
In case the name ‘LYMA’ rings a bell: yes, we have previously discussed the ‘the world’s first super supplement’ and the many claims made for it. We even had the pleasure of an interesting exchange with the above-pictured Dr Paul Clayton in the comments section of that post. Given the above, I am more than happy to welcome him, his LYMA team, and all other supplement peddlers who try to make a fast buck in the present crisis to the CVQC.
The ‘Corona-Virus Quackery Club’ (CVQC) is enjoying a fast-growing membership. As mentioned in previous posts, it consists of:
Chiropractors have been keen to join since weeks. They have a long tradition of claiming that their ‘adjustments’ boost the immune system, and therefore it was to be expected that they also jump on the corona-bandwagon.
Some chiropractors seem to believe that the corona-virus pandemic is a fine business opportunity or, as one put it, the perfect opportunity to have a heart to heart with patients about their immune and nervous systems! Remember, if germs automatically caused disease, the human race wouldn’t be around to debate the issue. Many forget that Louis Pasteur, the father of the germ theory recanted his belief. On his deathbed he observed, “It’s the soil, not the seed.” In other words, without the right environment, germs can do little harm.
Chiropractors and other health care workers are at greater risk due to patient or client interactions and are encouraged to take extra precautions when it comes to cleaning and disinfecting surfaces and skin or close contact.
“Every chiropractic practice has been touched by coronavirus [fears],” says Bill Esteb, DC, who has created and is circulating a coronavirus and chiropractic guide on how to avoid contracting the virus.
“We wanted to create a tool that chiropractors could use as a conversation springboard. Chiropractors need to remind their patients that germs don’t automatically cause disease. And that ‘catching’ the coronavirus, or anything else, requires a hospitable environment.”
The only way to catch anything, says Esteb, is to become a hospitable host. Flipping the message, Esteb in his coronavirus and chiropractic guide says here is “How to Catch the Coronavirus”:
- Eat a Poor Diet — Make sure your body lacks the vitamins, minerals, enzymes and micronutrients needed to keep itself in good repair.
- Avoid Adequate Rest — Stay up late and use sugar, tobacco, coffee and energy drinks as needed.
- Become Dehydrated — Reduce the effectiveness of your natural defense mechanisms by shunning adequate water.
- Stop Exercising — Reduce the efficiency of your lymphatic system, which requires movement to circulate this important germ-fighting fluid.
- Think Negative Thoughts — Worry that you’ll be a victim. Closely monitor news reports about outbreaks, fearing the advancing pandemic.
- Rarely Wash Your Hands — Use your dirty hands and fingers to rub your eyes, pick your nose or wipe your lips.
- Skip Your Chiropractic Adjustments — Handicap your nervous system, the master system that controls your entire body. Wait until symptoms are clearly present.
“Following these suggestions is the way to become a suitable host for any number of germs or microbes,” Esteb says. “The tongue-in-check approach keeps the subject light. It stimulates more instructive patient conversations. It helps reduce appointment cancellations.
“Most people have an inappropriate fear of germs. And while this poster and patient handout won’t eliminate it, use it to explore the value of ongoing chiropractic care as a preventive strategy.”
The Internet is full with messages of this type. Here is just one example: The best defense for the Corona Virus is to be healthy when you are exposed to the virus. Get adjusted to boost your immune system. Check out this video blog on what you can do to be healthy and prepare your body to fight off the corona virus.
Perhaps the worst excesses can be found on Twitter:
Friends of Science in Medicine (FSM) President, Assoc Professor Ken Harvey MB BS (Melb), FRCPA, AM congratulates Professor Jon Wardle, nurse and naturopath, with postgraduate qualifications in public health, law and health economics, on being appointed to Southern Cross University’s (SCU) Maurice Blackmore Chair of Naturopathic Medicine in Lismore. Professor Wardle has also been appointed as Foundation Director of the National Centre for Naturopathic Medicine (NCNM) funded with $10 Million from the Blackmore Foundation set up to sponsor research into ‘complementary medicine’.
Vice Chancellor, Professor Adam Shoemaker BA (Hons), PhD (ANU), researcher in Indigenous literature and culture, said the benefits of basing the NCNM at Southern Cross were enormous, “Being in a region like the Northern Rivers of New South Wales means we have brilliant local networks in this field. We are also supported by a local community who, like the University, are really receptive to trying new things in order to create a healthier future”.
Professor Harvey comments, “Professor Wardle certainly has challenges ahead. The Northern Rivers region is the anti-vax capital of Australia and some naturopaths advise against vaccination. Degree courses in naturopathy such as the Torrens Bachelor of Health Science (Naturopathy) degree, include studies of homeopathy, iridology and flower essence therapy. None have scientific evidence of efficacy”.
FSM has long argued that health care should be based on scientifically sound research, published in peer-reviewed journals of accepted standing. FSM is equally concerned about medical practitioners offering unproven and often exploitative treatments as it is about complementary medicine practitioners. Professor Harvey said, “some naturopaths practicing in Lismore, associated with SCU, work at clinics that use unverified laboratory tests to make dubious diagnoses and recommend treatment programs that lack evidence of efficacy”.
Professor Harvey (and FSM) conclude that there is an urgent need for evidence-based science to be applied to naturopathy. They trust that Professor Wardle will emulate Professor Edzard Ernst, Foundation Professor of Complementary Medicine at Exeter University, by applying accepted scientific standards to the evaluation of naturopathic interventions.
The March 24 opening of the NCNM in Lismore will feature a panel discussion on the future of health care with guest speakers: Professor Kerryn Phelps AM, former President of the Australasian Integrative Medicine Association, Marcus Blackmore AM, naturopath and Executive Director of Blackmores Ltd, which markets vitamin and herbal products, and Professor Jon Wardle. FSM hopes that the panel will discuss some of the issues raised above.
Sounds exciting, but is Wardle up to the job?
Judging from his publication record, he is certainly a naturopath through and through. He has published lots of papers; as far as I can see most of them are surveys of some sort or another. Many leave me somewhat bewildered. Two examples must suffice:
Objectives: To explore the recommendations of naturopathic medicine for the management of endometriosis, dysmenorrhea, and menorrhagia, drawing on traditional and contemporary sources.
Design: Content analysis.
Setting: Australia, Canada, and the United States of America (USA).
Subjects: Contemporary sources were identified from reviewing naturopathic higher education institutions’ recommended texts, while traditional sources were identified from libraries which hold collections of naturopathic sources. Sources were included if they were published from 1800 to 2016, were in English, published in Australia, Canada, or the USA, and reported on the topic. Included sources were as follows: 37 traditional texts; 47 contemporary texts; and 83 articles from naturopathic periodicals.
Results: Across included sources, the most reported disciplines were herbal medicine, clinical nutrition, mineral medicines, homeopathy, hydrotherapy, and chemical-based medicines. Herbal medicines were extensively reported from all sources for the management of endometriosis, dysmenorrhea, and menorrhagia. Clinical nutrition was only recommended from contemporary sources for all three conditions. Mineral medicines were mentioned in both traditional and contemporary sources, but were only recommended for dysmenorrhea and menorrhagia. There were limited recommendations for homeopathy and hydrotherapy treatments in all conditions across all sources. Chemical-based medicines were only mentioned for dysmenorrhea and menorrhagia, and recommendations ceased after 1922. Recommendations for endometriosis were not present in any of the traditional sources, across all reported disciplines.
Conclusions: The findings of this article provide insights into the documented historical and contemporary treatments within naturopathic medicine for endometriosis, dysmenorrhea, and menorrhagia. While philosophical principles remain the core of naturopathic practice, the therapeutic armamentarium appears to have changed over time, and a number of the original naturopathic treatments appear to have been retained as key elements of treatment for these conditions. Such insights into naturopathic treatments will be of particular interest to clinicians providing care to women, educators designing and delivering naturopathic training, and researchers conducting clinical and health service naturopathic research.
Complementary and alternative medicine (CAM) is an increasingly prevalent part of contemporary health care. Whilst there have been some attempts to understand the dynamics of CAM integration in the health care system from the perspective of conventional care providers and patients, little research has examined the view of CAM practitioners. This study aims to identify the experiences of integration within a conventional healthcare system as perceived by naturopaths. Qualitative semi-structured interviews were conducted using a purposeful sample of 20 practising naturopaths in South East Queensland, Australia to discuss their experiences and perceptions of integrating with conventional medical providers. Analysis of the interviews revealed five broad challenges for the integration of CAM according to naturopaths: competing paradigms between CAM and conventional medicine; co-option of CAM by conventional medical practitioners; the preservation of separate CAM and conventional medical worlds by patients and providers due to lack of formalised relations; negative feedback and biases created through selective or limited experience or information with CAM; and indifferent, reactive and one-sided interaction between CAM and conventional medical providers. Naturopaths support the integration of health services and attempt to provide safe and appropriate care to their patients through collaborative approaches to practice. The challenges identified by naturopaths associated with integration of CAM with conventional providers may impact the quality of care of patients who choose to integrate CAM and conventional approaches to health. Given the significant role of naturopaths in contemporary health-care systems, these challenges require further research and policy attention.
So, is Jon Wardle up to the job?
The answer obviously depends on what the job is.
If it is about publishing 100 more surveys that show nothing of much value and are essentially SCAM-promotion, then he ought to be fine. If it is about rigorously testing which SCAMs generate more good than harm, then ‘Houston, we have a problem’!
Today is Valentine’s Day, a good moment to take a critical look at some of the libido-boosters so-called alternative medicine (SCAM) has to offer. The Internet offers plenty; this website, for instance, advertises over 20 different natural (mostly botanical) products. But such sites are typically thin on evidence.
A quick Medline search locates plenty of research. Much of it seems to be on rats which is not so relevant – unless, of course, your husband is a rat. In terms of clinical trials, Medline too is not all that informative. Here are some of the studies I found:
Eurycoma longifolia is reputed as an aphrodisiac and remedy for decreased male libido. A randomized, double-blind, placebo controlled, parallel group study was carried out to investigate the clinical evidence of E. longifolia in men. The 12-week study in 109 men between 30 and 55 years of age consisted of either treatment of 300 mg of water extract of E. longifolia (Physta) or placebo. Primary endpoints were the Quality of Life investigated by SF-36 questionnaire and Sexual Well-Being investigated by International Index of Erectile Function (IIEF) and Sexual Health Questionnaires (SHQ); Seminal Fluid Analysis (SFA), fat mass and safety profiles. Repeated measures ANOVA analysis was used to compare changes in the endpoints. The E. longifolia (EL) group significantly improved in the domain Physical Functioning of SF-36, from baseline to week 12 compared to placebo (P = 0.006) and in between group at week 12 (P = 0.028). The EL group showed higher scores in the overall Erectile Function domain in IIEF (P < 0.001), sexual libido (14% by week 12), SFA- with sperm motility at 44.4%, and semen volume at 18.2% at the end of treatment. Subjects with BMI ≥ 25 kg/m(2) significantly improved in fat mass lost (P = 0.008). All safety parameters were comparable to placebo.
Yoga is a popular form of complementary and alternative treatment. It is practiced both in developing and developed countries. Use of yoga for various bodily ailments is recommended in ancient ayvurvedic (ayus = life, veda = knowledge) texts and is being increasingly investigated scientifically. Many patients and yoga protagonists claim that it is useful in sexual disorders. We are interested in knowing if it works for patients with premature ejaculation (PE) and in comparing its efficacy with fluoxetine, a known treatment option for PE. Aim: To know if yoga could be tried as a treatment option in PE and to compare it with fluoxetine. Methods: A total of 68 patients (38 yoga group; 30 fluoxetine group) attending the outpatient department of psychiatry of a tertiary care hospital were enrolled in the present study. Both subjective and objective assessment tools were administered to evaluate the efficacy of the yoga and fluoxetine in PE. Three patients dropped out of the study citing their inability to cope up with the yoga schedule as the reason. Main outcome measure: Intravaginal ejaculatory latencies in yoga group and fluoxetine control groups. Results: We found that all 38 patients (25-65.7% = good, 13-34.2% = fair) belonging to yoga and 25 out of 30 of the fluoxetine group (82.3%) had statistically significant improvement in PE. Conclusions: Yoga appears to be a feasible, safe, effective and acceptable nonpharmacological option for PE. More studies involving larger patients could be carried out to establish its utility in this condition.
Antidepressants including selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs) are known to cause secondary sexual dysfunction with prevalence rates as high as 50%-90%. Emerging research is establishing that acupuncture may be an effective treatment modality for sexual dysfunction including impotence, loss of libido, and an inability to orgasm. Objectives: The purpose of this study was to examine the potential benefits of acupuncture in the management of sexual dysfunction secondary to SSRIs and SNRIs. Subjects: Practitioners at the START Clinic referred participants experiencing adverse sexual events from their antidepressant medication for acupuncture treatment at the Mood and Anxiety Disorders, a tertiary care mood and anxiety disorder clinic in Toronto. Design: Participants received a Traditional Chinese Medicine assessment and followed an acupuncture protocol for 12 consecutive weeks. The acupuncture points used were Kidney 3, Governing Vessel 4, Urinary Bladder 23, with Heart 7 and Pericardium 6. Participants also completed a questionnaire package on a weekly basis. Outcomes measured: The questionnaire package consisted of self-report measures assessing symptoms of depression, anxiety, and various aspects of sexual function. Results: Significant improvement among male participants was noted in all areas of sexual functioning, as well as in both anxiety and depressive symptoms. Female participants reported a significant improvement in libido and lubrication and a nonsignificant trend toward improvement in several other areas of function. Conclusions: This study suggests a potential role for acupuncture in the treatment of the sexual side-effects of SSRIs and SNRIs as well for a potential benefit of integrating medical and complementary and alternative practitioners.
The primary objectives were to compare the efficacy of extracts of the plant Tribulus terrestris (TT; marketed as Tribestan), in comparison with placebo, for the treatment of men with erectile dysfunction (ED) and with or without hypoactive sexual desire disorder (HSDD), as well as to monitor the safety profile of the drug. The secondary objective was to evaluate the level of lipids in blood during treatment. Participants and design: Phase IV, prospective, randomized, double-blind, placebo-controlled clinical trial in parallel groups. This study included 180 males aged between 18 and 65 years with mild or moderate ED and with or without HSDD: 90 were randomized to TT and 90 to placebo. Patients with ED and hypertension, diabetes mellitus, and metabolic syndrome were included in the study. In the trial, an herbal medicine intervention of Bulgarian origin was used (Tribestan®, Sopharma AD). Each Tribestan film-coated tablet contains the active substance Tribulus terrestris, herba extractum siccum (35-45:1) 250mg which is standardized to furostanol saponins (not less than 112.5mg). Each patient received orally 3×2 film-coated tablets daily after meals, during the 12-week treatment period. At the end of each month, participants’ sexual function, including ED, was assessed by International Index of Erectile Function (IIEF) Questionnaire and Global Efficacy Question (GEQ). Several biochemical parameters were also determined. The primary outcome measure was the change in IIEF score after 12 weeks of treatment. Complete randomization (random sorting using maximum allowable% deviation) with an equal number of patients in each sequence was used. This randomization algorithm has the restriction that unequal treatment allocation is not allowed; that is, all groups must have the same target sample size. Patients, investigational staff, and data collectors were blinded to treatment. All outcome assessors were also blinded to group allocation. Results: 86 patients in each group completed the study. The IIEF score improved significantly in the TT group compared with the placebo group (Р<0.0001). For intention-to-treat (ITT) there was a statistically significant difference in change from baseline of IIEF scores. The difference between TT and placebo was 2.70 (95% CI 1.40, 4.01) for the ITT population. A statistically significant difference between TT and placebo was found for Intercourse Satisfaction (p=0.0005), Orgasmic Function (p=0.0325), Sexual Desire (p=0.0038), Overall Satisfaction (p=0.0028) as well as in GEQ responses (p<0.0001), in favour of TT. There were no differences in the incidence of adverse events (AEs) between the two groups and the therapy was well tolerated. There were no drug-related serious AEs. Following the 12-week treatment period, significant improvement in sexual function was observed with TT compared with placebo in men with mild to moderate ED. TT was generally well tolerated for the treatment of ED.
What makes me suspicious about these trials is that:
- they are mostly on the flimsy side,
- there are as good as no independent replications,
- they all report positive outcomes. I was unable to find a single study where the authors concluded: SORRY, BUT THIS STUFF IS USELESS!
Disappointed with the quality and the content of the existing trials, I am now off to buy some oysters!
About 85% of German children are treated with herbal remedies. Yet, little is known about the effects of such interventions. A new study might tell us more.
This analysis accessed 2063 datasets from the paediatric population in the PhytoVIS data base, screening for information on indication, gender, treatment, co-medication and tolerability. The results suggest that the majority of patients was treated with herbal medicine for the following conditions:
- common cold,
- digestive complaints,
- skin diseases,
- sleep disturbances
The perceived effect of the therapy was rated in 84% of the patients as very good or good without adverse events.
The authors concluded that the results confirm the good clinical effects and safety of herbal medicinal products in this patient population and show that they are widely used in Germany.
If you are a fan of herbal medicine, you will be jubilant. If, on the other hand, you are a critical thinker or a responsible healthcare professional, you might wonder what this database is, why it was set up and how exactly these findings were produced. Here are some details:
The data were collected by means of a retrospective, anonymous, one-off survey consisting of 20 questions on the user’s experience with herbal remedies. The questions included complaints/ disease, information on drug use, concomitant factors/diseases as well as basic patient data. Trained interviewers performed the interviews in pharmacies and doctor’s offices. Data were collected in the Western Part of Germany between April 2014 and December 2016. The only inclusion criterion was the intake of herbal drugs in the last 8 weeks before the individual interview. The primary endpoint was the effect and tolerability of the products according to the user.
And who participated in this survey? If I understand it correctly, the survey is based on a convenience sample of parents using herbal remedies. This means that those parents who had a positive experience tended to volunteer, while those with a negative experience were absent or tended to refuse. (Thus the survey is not far from the scenario I often use where people in a hamburger restaurant are questioned whether they like hamburgers.)
So, there are two very obvious factors other than the effectiveness of herbal remedies determining the results:
- selection bias,
- lack of objective outcome measure.
This means that conclusions about the clinical effects of herbal remedies in paediatric patients are quite simply not possible on the basis of this survey. So, why do the authors nevertheless draw such conclusions (without a critical discussion of the limitations of their survey)?
Could it have something to do with the sponsor of the research?
The PhytoVIS study was funded by the Kooperation Phytopharmaka GbR Bonn, Germany.

WHAT DO YOU THINK?
Even the NEW SCIENTIST seems alarmed about Gwyneth and her activities:
Psychic readings, energy healing and vampire facials are just a few of the adventures had by actor and alternative health guru Gwyneth Paltrow and her team in her forthcoming Netflix series The Goop Lab. Goop, Paltrow’s natural health company, has already become a byword for unrestrained woo, but the TV series takes things to the next level.
Don’t make the mistake of thinking you can stick your fingers in your ears and pretend it isn’t happening. There is unlikely to be any escape from The Goop Lab after it is released on 24 January, judging by the current explosion of interest in Goop’s latest offering, a candle scented like Paltrow’s vagina, which has reportedly sold out…
Yet, I am sure we got her all wrong!
Good old Gwennie is really one of us – she is a true sceptic!
Think about it; it’s the only explanation.
When she first started dabbling in woo, she only wanted to test us. I’ll just display a few cupping marks and see how they react, she thought.
Then she saw that most people were so gullible that they bought it. Of course, she thought, if they buy it, I might as well take their money. In her attempt to see how far she can push her boat out, she decided to conduct a sceptical experiment and went further and further. This is when she started to focus on her vagina – jade eggs, steaming it, etc. Surely, she thought, eventually they must realise that I am a sceptic taking the Mikey!
But they never did realise it; at least not so far.
So, she decided to do something even more brazen and sell candles to dispense the smell of her vagina in the homes of her fans. That will do it, she felt, now they will realise what I want to achieve with all this.
But what happened? They sold out in no time (actually, both the candles and the gullible public)! That was a surprise even to our Gwennie. She thought she had seen it all, but she was wrong.
Now she is trying to think of something even more outrageous – but she admits, it’s not easy. What can be a more obvious and disgusting hoax than filling people’ homes with the smell of my genitals and let them pay through their noses for the pleasure? she asks herself.
Yes, poor old Gwennie is at loss! Stuck in her own vagina, so to speak.
Perhaps you can help her? Please suggest what vaginal gimmick she might sell next to make her position inescapably clear to even the dumbest of the gullible. Just mention your ideas in the comment section below; I have a feeling she is an avid reader of this blog. Gwennie might even show herself generous; if she likes your innovation, she will certainly make it worth your while.
Because, by Jove, she can afford to be generous. Apparently her business is now worth a quarter of a billion US$. But we must not be envious. Knowing that she did all this merely to stimulate sceptical thinking in the general public, you will not be surprised to learn what she intends to do with all this dosh: once she has succeeded in demonstrating to all the gullible pin heads and devotees that she really is on the side of the angles, she will donate all of it to sceptic organisations across the globe.
So, sceptics of the world: stop snarling at my friend Gwennie, rejoice and prepare for a major windfall.
Are you hungover today? you will be pleased to hear that so-called alternative medicine (SCAM) has a lot to offer – at least this is what its enthusiasts think.
Homeopaths swear by Nux Vomica as the first remedy to think of with hangover headaches, but it is also excellent for headaches from overwork, indigestion headaches and headaches accompanying constipation. Use it when your headache is worse when you cough or bend down, and headaches that aggravate when you move your eyes. If you have overeaten and drunk too much alcohol, you may also feel nauseous and want to vomit to make yourself feel better but find you cannot. If this describes your symptoms then Nux Vomica is the remedy for you.
When I worked as a homeopath, I and others often tried this treatment – it never worked. More importantly, there is not a jot of evidence that it does.
Some people recommend artichoke extract. I say: forget it. Here is why:
Extract of globe artichoke (Cynara scolymus) is promoted as a possible preventive or cure for alcohol-induced hangover symptoms. However, few rigorous clinical trials have assessed the effects of artichoke extract, and none has examined the effects in relation to hangovers. We undertook this study to test whether artichoke extract is effective in preventing the signs and symptoms of alcohol-induced hangover.
We recruited healthy adult volunteers between 18 and 65 years of age to participate in a randomized double-blind crossover trial. Participants received either 3 capsules of commercially available standardized artichoke extract or indistinguishable, inert placebo capsules immediately before and after alcohol exposure. After a 1-week washout period the volunteers received the opposite treatment. Participants predefined the type and amount of alcoholic beverage that would give them a hangover and ate the same meal before commencing alcohol consumption on the 2 study days. The primary outcome measure was the difference in hangover severity scores between the artichoke extract and placebo interventions. Secondary outcome measures were differences between the interventions in scores using a mood profile questionnaire and cognitive performance tests administered 1 hour before and 10 hours after alcohol exposure.
Fifteen volunteers participated in the study. The mean number (and standard deviation) of alcohol units (each unit being 7.9 g, or 10 mL, of ethanol) consumed during treatment with artichoke extract and placebo was 10.7 (3.1) and 10.5 (2.4) respectively, equivalent to 1.2 (0.3) and 1.2 (0.2) g of alcohol per kilogram body weight. The volume of nonalcoholic drink consumed and the duration of sleep were similar during the artichoke extract and placebo interventions. None of the outcome measures differed significantly between interventions. Adverse events were rare and were mild and transient.
Our results suggest that artichoke extract is not effective in preventing the signs and symptoms of alcohol-induced hangover. Larger studies are required to confirm these findings.
Is there anything else you might want to try? I am afraid the answer is NO. Here is our systematic review on the subject:
To assess the clinical evidence on the effectiveness of any medical intervention for preventing or treating alcohol hangover.
Systematic searches on Medline, Embase, Amed, Cochrane Central, the National Research Register (UK), and ClincalTrials.gov (USA); hand searches of conference proceedings and bibliographies; contact with experts and manufacturers of commercial preparations. Language of publication was not restricted.
STUDY SELECTION AND DATA EXTRACTION:
All randomised controlled trials of any medical intervention for preventing or treating alcohol hangover were included. Trials were considered if they were placebo controlled or controlled against a comparator intervention. Titles and abstracts of identified articles were read and hard copies were obtained. The selection of studies, data extraction, and validation were done independently by two reviewers. The Jadad score was used to evaluate methodological quality.
Fifteen potentially relevant trials were identified. Seven publications failed to meet all inclusion criteria. Eight randomised controlled trials assessing eight different interventions were reviewed. The agents tested were propranolol, tropisetron, tolfenamic acid, fructose or glucose, and the dietary supplements Borago officinalis (borage), Cynara scolymus (artichoke), Opuntia ficus-indica (prickly pear), and a yeast based preparation. All studies were double blind. Significant intergroup differences for overall symptom scores and individual symptoms were reported only for tolfenamic acid, gamma linolenic acid from B officinalis, and a yeast based preparation.
No compelling evidence exists to suggest that any conventional or complementary intervention is effective for preventing or treating alcohol hangover. The most effective way to avoid the symptoms of alcohol induced hangover is to practise abstinence or moderation.
Yes, it’s true, the only sound advice is moderation!
