This meta-analysis was performed “to ascertain the effectiveness of oral aloe vera consumption on the reduction of fasting blood glucose (FBG) and hemoglobin A1c (HbA1c).”
PubMed, CINAHL, Natural Medicines Comprehensive Database, and Natural Standard databases were searched. The searches were limited to clinical trials or observational studies conducted in humans and published in English. Studies of aloe vera’s effect on FBG, HbA1c, homeostasis model assessment-estimated insulin resistance (HOMA-IR), fasting serum insulin, fructosamine, and oral glucose tolerance test (OGTT) in prediabetic and diabetic populations were examined.
Nine studies were included in the FBG parameter (n = 283); 5 of these studies included HbA1c data (n = 89). Aloe vera decreased FBG by 46.6 mg/dL (p < 0.0001) and HbA1c by 1.05% (p = 0.004). Significant reductions of both endpoints were maintained in all subgroup analyses. Additionally, the data suggested that patients with an FBG ≥200 mg/dL may see a greater benefit. A mean FBG reduction of 109.9 mg/dL was observed in this population (p ≤ 0.0001). There was evidence of publication bias with FBG but not with HbA1c.
The authors concluded that the results of this meta-analysis support the use of oral aloe vera for significantly reducing both FBG (46.6 mg/dL) and HbA1c (1.05%) in prediabetic and diabetic patients. However, given the current overall quality and relative scarcity of data, further clinical studies that are more robust and better controlled are warranted to confirm and further explore these findings.
Oh no, the results do not support the use of aloe vera at all!!
Because this ‘meta-analysis’ is of unacceptably poor quality. Here are just some of the flaws that render it totally useless, particularly for issuing advice such as above:
- The authors included uncontrolled observational studies which make no attempt to control for non-specific effects.
- In several studies, the use of concomitant anti-diabetic medications was allowed; therefore it is not possible to establish cause and effect by aloe vera.
- The search strategy was woefully inadequate; for instance non-English publications were not considered.
- There was no assessment of the scientific rigor of the included studies; this totally invalidates the reliably of the conclusions.
- The included studies used preparations of widely different aloe vera preparations, and there is no way of knowing the does of the active ingredients.
Diabetes is a serious condition that affects millions worldwide. If some of these patients are sufficiently gullible to follow the conclusions of this paper, they might be dead within a matter of days. This makes this article one of the most dangerous papers that I have seen in the ‘peer-reviewed’ literature of alternative medicine.
Who publishes such utter and irresponsible rubbish?
You may well ask.
The journal has been discussed on this blog before for the junk that regularly appears in its pages, and so has its editor in chief. The authors (and the reviewers) are not known to me, but one thing is for sure: they don’t know the first thing about conducting a decent systematic review/meta-analysis.
A press-release from a company based in Germany recently caught my attention. I here present only the most relevant sections from this document:
Natural remedies like medicinal mushrooms also called vitality mushrooms haven proven helpful in prevention and as a support in the therapy, of diabetes type 2. This could be shown by long-time observational studies in naturopathy, for example by MykoTroph – Institute for Medicinal Mushrooms. Medicinal mushroom Coprinus has regenerating effects on the pancreas; it also helps the sensitization of the receptors responsible for the absorption of insulin and claims to have a blood sugar lowering effect.
Medicinal mushroom Maitake has positive effects on the fat metabolism and the sensitivity of insulin receptors. Diabetes type 2 is often linked to circulation problems, vascular diseases and hypertension. Therefore, regular monitoring of the blood pressure, blood lipids, triglycerides and body weight is highly important. The intake of Maitake can help ‒ even in a preliminary stage ‒ to get a grip on these determining factors.
Within the scope of a holistic therapy of diabetes type 2 with metabolic syndrome, the combined intake of medicinal mushrooms and Nopal juice (prickly pear) can be very reasonable. Nopal juice has a lowering effect on the glycemic index of ingested food. The consequence is a slower release of carbohydrates in the intestines and is therefore favorable for a healthy level of blood sugar…
Medicinal mushrooms are available as mushroom powder capsules. According to observational studies of MykoTroph – Institute for Medicinal Mushrooms, especially mushroom powder derived from the whole mushroom has proven effective. Only if the mushroom powder is derived from the whole mushroom, the powder will contain all of the effective ingredients of medicinal mushrooms. It should also be taken care that the mushrooms are from certified organic production. For further information, please visit us on http://www.mykotroph.com
a Japanese study participants comprised 726 Japanese T2DM outpatients free of history of CVD. Life styles were analyzed using self-reported questionnaires. The relationship between dietary patterns, identified by factor analysis, and potential risk factors for CVD was investigated by linear and logistic regression analyses….The “Seaweeds, Vegetables, Soy products and Mushrooms” pattern, characterized by high consumption of seaweeds, soy products and mushrooms, was associated with lower use of diabetes medication and healthier lifestyles.
END OF QUOTE
These are claims that could be relevant to millions of diabetic patients worldwide – but are they true?
The study cited above did indeed show an association; but an association is not necessarily a causal relationship! So what evidence is there fore a causal relationship between mushroom-consumption and diabetes? The answer is: frustratingly little.
A Cochrane review concluded that “evidence from a small number of randomised controlled trials does not support the use of G lucidum [Ganoderma lucidum (also known as lingzhi or reishi)] for treatment of cardiovascular risk factors in people with type 2 diabetes mellitus. Future research into the efficacy of G lucidum should be placebo-controlled and adhere to clinical trial reporting standards.”
The authors of another Cochrane review concluded that “our review did not find sufficient evidence to justify the use of G. lucidum as a first-line treatment for cancer. It remains uncertain whether G. lucidum helps prolong long-term cancer survival. However, G. lucidum could be administered as an alternative adjunct to conventional treatment in consideration of its potential of enhancing tumour response and stimulating host immunity. G. lucidum was generally well tolerated by most participants with only a scattered number of minor adverse events. No major toxicity was observed across the studies. Although there were few reports of harmful effect of G. lucidum, the use of its extract should be judicious, especially after thorough consideration of cost-benefit and patient preference. Future studies should put emphasis on the improvement in methodological quality and further clinical research on the effect of G. lucidum on cancer long-term survival are needed. An update to this review will be performed every two years.”
A further study determined whether a supplement of Agaricus blazei Murill extract improves insulin resistance in type 2 diabetes. It was designed as a clinical randomized, double-blind, placebo-controlled trial. Diabetic patients were randomly assigned to either receiving supplement of Agaricus blazei Murill (ABM) extract or placebo (cellulose) 1500 mg daily for 12 weeks. At the end of the study, the subjects who received supplement of ABM extract (n = 29) showed significantly lower HOMA-IR index than the control group (n = 31). The plasma adiponectin concentration increased by 20% in the ABM group after 12 weeks of treatment, but decreased 20% among those taking the placebo. The authors concluded that “ABM extract improves insulin resistance among subjects with type 2 diabetes. The increase in adiponectin concentration after taking AMB extract for 12 weeks might be the mechanism that brings the beneficial effect. Studies with longer periods of follow-up should be conducted in the future.”
On the basis of all this evidence, it seems fair to conclude that mushrooms have little or no effect on diabetes.
And what about the above press-release?
Diabetes is a serious condition that can be well-controlled with diet, exercise and drugs. Many diabetics are nevertheless fed up with taking drugs throughout their entire life and would only be too happy to exchange them for ‘something natural’. Therefore patients might try mushrooms or other natural ‘cures’, if they are promoted in this way. However, this decision could prove fatal (examples of such tragedies abound).
In view of these considerations, I find such promotion irresponsible, unethical and outright dangerous.
Prince Charles’ views on health have repeatedly taken centre stage on this blog. And rightly so; they are often weird and wonderful. In 2013, for instance, I quoted them extensively:
Charles stands for…”the kind of care that integrates the best of new technology and current knowledge with ancient wisdom. More specifically, perhaps, it is an approach to care of the patient which includes mind, body and spirit and which maximizes the potential of conventional, lifestyle and complementary approaches in the process of healing”. Charles believes that conventional medicine aims “to treat the symptoms of disease” his vision of a post-modern medicine therefore is “actively to create health and to put the patient at the heart of this process by incorporating those core human elements of mind, body and spirit…This whole area of work – what I can only describe as an ‘integrated approach’ in the UK, or ‘integrative’ in the USA – takes what we know about appropriate conventional, lifestyle and complementary approaches and applies them to patients. I cannot help feeling that we need to be prepared to offer the patient the ‘best of all worlds’ according to a patient’s wishes, beliefs and needs“. Charles also points out that “health inequalities have lowered life-expectancy” in parts of the UK and suggests, if we “tackle some of these admittedly deep-seated problems, not only do you begin to witness improvements in health and other inequalities, but this can lead to improvements in the overall cost-efficiency and effectiveness of local services.“
Sounds alright? Well – at least it is touching to see how he is concerned about inequalities in the UK!
But the royal and no doubt well-intended views need to be followed by royal actions. If not, such words might degenerate into royal BS. If Charles is so keen on giving us all THE BEST OF BOTH WORLDS, he should stop promoting outright quackery such as homeopathic remedies. They contain nothing but sugar! But that is one substance Charles seems to be rather fond of, regardless of the harm it can do in high doses to public health.
Recently, Prince Charles has been criticised by health campaigners for the high sugar content of his Duchy Organic ice cream. The Duchy Organic vanilla ice cream contains 14.5g of sugar per 100g, almost double the amount of Asda’s ‘smart price’ vanilla ice cream which has 7.9g sugar per 100g. If that wasn’t enough of a blow to the Prince’s brand, the Asda ice cream is also much more affordable at 85p for two litres – compared with £3.49 for every 750ml tub of the Duchy Organic product. Charles’ Dutchy Originals products are sold by Waitrose, and a spokesman of the retailer said: “Waitrose Duchy Organic vanilla ice cream is an indulgent product which is not aimed at children.”
Indulgent like in ‘expensive’? So much for inequalities, Charles.
But let’s not go there; let’s be constructive; after all, the man is full of good will, isn’t he?
I recommend the R&D department of Dutchy Originals put their profits and Charles convictions to good use. Specifically, I suggest they start a research programme on the homeopathic cure for sugar-induced obesity. If Charles is correct, and LIKE CURES LIKE, the obesity epidemic in the UK should be treatable with the very cause of excess body weight. It follows that potentised sugar ought to be a cure for obesity.
I can see it now: DUTCHY ORIGINALS – ‘SUGAR C30’, £15.99 per 10g.
Many people seem to believe that homeopathy is harmless. It is a belief that can easily be shown to be wrong, and this blog has repeatedly done just that. Perhaps the best researched issue here is the stance of many homeopaths against vaccination. But this is by no means all.
There are uncounted books, articles and websites which mislead consumers into believing that they can cure their illnesses with homeopathy. Take the website of ‘STAR HOMEOPATHY’ for instance. This organisation makes fantastic promises:
Star homeopathy, a chain of super specialty homeopathic clinic’s founded by a group of practically high qualified doctors with the vision to provide the best medical treatment in a scientific and most advanced way with the use of latest clinical knowledge and medical diagnostic equipment.

Patients suffering from diabetes, for instance. They might hope that STAR HOMEOPATHY has a solution for them. And true enough, they do:
How Homoeopathy helps to cure Diabetes?
In homeopathy, diabetes is seen as a reflection of the body’s inability to function optimally. There is an imbalance that results in the body’s incapacity to effectively utilize the insulin that it produces, or to produce sufficient insulin for its needs. While symptoms often disappear after conventional treatment, the vital force does not. Homoeopathy can be used effectively in the treatment of diabetes. Here we mainly concentrate on functioning of the pancreas in efficient insulin production. The metabolic condition of a patient suffering from diabetes requires both therapeutic and nutritional measures to correct the illness. Homeopathy can regulate sugar metabolism while helping to resolve the metabolic disturbances that lead to diabetes. Furthermore, homeopathy helps stimulate the body’s self-healing powers in order to prevent complications such as open leg sores and other dysfunctions of the blood vessel, loss of vision, kidney failure. Homeopathic treatment does not target one illness, an organ, a body part or a symptom. Remedies are prescribed based on an assembly of presenting symptoms, their stresses in life.
Commonly indicated Homoeopathic remedies:
Syzygium: A most useful remedy in diabetes mellitus. No other remedy causes in so marked degree the diminution and disappearance of sugar in the urine. Prickly heat in upper part of the body; small red pimples itch violently. Great thirst, weakness, emaciation. Very large amounts of urine.. Diabetic ulceration.. Syzygium Jambolanum has marked action on diabetes mellitus as it causes marked diminution of sugar in urine. Great thirst with weakness, emaciation inspite of proper nutritious diet. Profuse urination of high specific gravity. Small red pimples with much itching. Syzygium Jambolanum also helps in treating old ulcers of skin associated with diabetes mellitus.
Uranium nitricum: Uranium Nitricum is a chief diuretic remedy. There is copious urination with incontinence of urine. It is indicated in glycosuria with increased urination, emaciation and tympanites. Uranium Nitiricum also helps in enuresis, the patient is unable to retain urine without pain. Burning in urethra, with very acid urine. There is a tendency to great emaciation, debility and general dropsy. Causes glycosuria and increased urine. Is known to produce nephritis, diabetes, degeneration of the liver, high blood pressure and dropsy. Its therapeutic keynote is Great emaciation, debility and tendency to ascites and general dropsy. Backache and delayed menses. Dry mucous membranes and skin.
Lycopodium: Diabetes. Anger during disease. Lost of self confidence. The right side conditions works well and thus improve the liver and kidney functioning as conditions Neuropathy. There is constipation due to inactivity of the rectum. Impotence. Intense desire for sweets.
So, if you think that homeopathy is harmless, think again!
Following this advice, could mean the death of many diabetics.
No treatment for which hugely exaggerated claims abound can ever be safe.
I recently tweeted the following short text: “THIS IS HOW HOMEOPATHY CAN KILL MILLIONS” and provided a link to a website where a homeopaths advocated using homeopathy to control blood sugar levels in diabetic patients. The exact text I objected to is reproduced below:
“Management of Blood sugar
The commonly used remedies are Uranium Nitricum, Phosphoric Acid, Syzygium Jambolanum, Cephalandra Indica etc. These are classical Homeopathic remedies. These are used in physiologically active doses such as Mother tincture, 3x etc. depending up on the level of the blood sugar and the requirement of the patient. Several pharmaceutical companies have also brought in propriety medicines with a combination of the few Homeopathic medicines. Biochemic remedies which is a part of Homeopathy advocates Biocombination No 7 as a specific for Diabetes. Another Biochemic medicine Natrum Phos 3x is widely used with a reasonable success in controlling the blood sugar. Scientific studies on the impact of homeopathic medicines in bringing down blood sugar are limited, but many of the above remedies have some positive effects either as a stand-alone remedy or as an adjunct along with other medications.”
A clearly annoyed homeopath responded by tweeting: “homeopathy has been a favorite complement to diabetes treatment for over 200 yrs. Your evidence of the contrary is?”
So I better explain to her what I mean, and as this cannot be done in 140 characters, I do it with this post instead.
The claim expressed on the website is not that homeopathy can complement diabetes treatment; the claim is clearly that it can be a sole treatment and a replacement of conventional anti-diabetic treatment. There is, of course, no evidence at all for that. If patients put this claim to the test, many will die. Because there are many millions of diabetics worldwide, this claim has the potential to kill millions. In other words, my initial tweet was perhaps blunt but certainly correct.
Now to the notion of homeopathy as a ‘complement to diabetes treatment’: do I have evidence to the contrary? I think that is entirely the wrong question. The true question here is whether homeopaths who claim that homeopathic remedies can be an effective adjunct to conventional anti-diabetic treatments have any evidence for their claim (after all, in health care, as in most other walks of life, it is the one who makes a claim who has to prove it, not the one who doubts it!). So, is there good evidence?
To the best of my knowledge, the answer is NO!
If you disagree, please show me the evidence.
If you have diabetes, chances are that you need life-long treatment. Before effective anti-diabetic medications became available, diabetes amounted to a death sentence. Fortunately, these times are long gone.
…unless, of course, you decide to listen to the promises of alternative practitioners many of whom offer a cure for diabetes. Here is just one website of hundreds that does just that. The following is an abbreviated quote where I have changed nothing, not even the numerous spelling mistakes:
Modern medicine has no permanent cure for diabetes but alternative medicines like yoga ,mudra,ayurveda is very useful to control and even cure diabetes.Ayurveda is an alternative medicine to cure diabetes.
Alternative medicine like ayurveda is a best to cure diabetes naturally.
A serious disorder of the glands,of pancreas to be exact,is diabetes,or madhumeha as described in ayurveda.It is one of the most insidious disorders of the metabolism and,if left undiagnosed or untreated,it may lead to rapid emaciation and ultimately death…
Ayurveda medicines to cure diabetes
In ayurveda the following medicines have been recommended for this disease
Shiljita ————————–240 mg
Nyagrodadhi churna ———3 gm
These should be given twice after meals with decoction of arni.
Vasantakusumakara rasa —120 mg
Shudha Shilajit ————–240 mg
Nag Bhasma —————–120 mg
Haldi ————————–500 mg
Amlaki Churna ————-500 mg
Twice daily with powder of rose-apple stones.Twice daily with honey.
Chadraprabha Vati ——– 500 mg
Mudra the alternative treatment to cure diabetes naturally
Mudra is a non medical and no cost treatment to cure diabetes.You can perform mudras at any time or any position.It is an effective way of treatment you can get better result if you practice it regularly .
It goes without saying that none of these treatments would cure diabetes. A Cochrane review concluded that there is insufficient evidence at present to recommend the use of these interventions in routine clinical practice. It also goes without saying that not many patients would fall for the nonsense proclaimed on this or so many other websites. But even just one single patient dying because of some charlatan promising a cure for life-threatening diseases is one patient too many.
Many proponents of alternative medicine seem somewhat suspicious of research; they have obviously understood that it might not produce the positive result they had hoped for; after all, good research tests hypotheses and does not necessarily confirm beliefs. At the same time, they are often tempted to conduct research: this is perceived as being good for the image and, provided the findings are positive, also good for business.
Therefore they seem to be tirelessly looking for a study design that cannot ‘fail’, i.e. one that avoids the risk of negative results but looks respectable enough to be accepted by ‘the establishment’. For these enthusiasts, I have good news: here is the study design that cannot fail.
It is perhaps best outlined as a concrete example; for reasons that will become clear very shortly, I have chosen reflexology as a treatment of diabetic neuropathy, but you can, of course, replace both the treatment and the condition as it suits your needs. Here is the outline:
- recruit a group of patients suffering from diabetic neuropathy – say 58, that will do nicely,
- randomly allocate them to two groups,
- the experimental group receives regular treatments by a motivated reflexologist,
- the controls get no such therapy,
- both groups also receive conventional treatments for their neuropathy,
- the follow-up is 6 months,
- the following outcome measures are used: pain reduction, glycemic control, nerve conductivity, and thermal and vibration sensitivities,
- the results show that the reflexology group experience more improvements in all outcome measures than those of control subjects,
- your conclusion: This study exhibited the efficient utility of reflexology therapy integrated with conventional medicines in managing diabetic neuropathy.
This method is fool-proof, trust me, I have seen it often enough being tested, and never has it generated disappointment. It cannot fail because it follows the notorious A+B versus B design (I know, I have mentioned this several times before on this blog, but it is really important, I think): both patient groups receive the essential mainstream treatment, and the experimental group receives a useless but pleasant alternative treatment in addition. The alternative treatment involves touch, time, compassion, empathy, expectations, etc. All of these elements will inevitably have positive effects, and they can even be used to increase the patients’ compliance with the conventional treatments that is being applied in parallel. Thus all outcome measures will be better in the experimental compared to the control group.
The overall effect is pure magic: even an utterly ineffective treatment will appear as being effective – the perfect method for producing false-positive results.
And now we hopefully all understand why this study design is so very popular in alternative medicine. It looks solid – after all, it’s an RCT!!! – and it thus convinces even mildly critical experts of the notion that the useless treatment is something worth while. Consequently the useless treatment will become accepted as ‘evidence-based’, will be used more widely and perhaps even reimbursed from the public purse. Business will be thriving!
And why did I employ reflexology for diabetic neuropathy? Is that example not a far-fetched? Not a bit! I used it because it describes precisely a study that has just been published. Of course, I could also have taken the chiropractic trial from my last post, or dozens of other studies following the A+B versus B design – it is so brilliantly suited for misleading us all.
‘Red ginseng’ is an herbal medicine prepared by steaming raw ginseng. This process is believed to increase its pharmacological activity. Further conversion through fermentation is thought to increase its intestinal absorption and bioactivity to diminish its toxicity.
Red ginseng (RG) is traditionally used for diabetes. Our own systematic review of 4 RCTs concluded that the evidence for the effectiveness of RG in controlling glucose in type 2 diabetes is not convincing. Few included studies with various treatment regimens prohibit definitive conclusions. More rigorous studies are needed to clarify the effects of RG on this condition.
Now a new RCT has become available. This study was conducted to investigate the effects of daily supplementation with fermented red ginseng (FRG) on blood sugar levels in subjects with impaired fasting glucose or type 2 diabetes. It was a four-week long, randomized, double-blind, placebo-controlled trial. Forty-two subjects with impaired fasting glucose or type 2 diabetes were randomly allocated to two groups assigned to consume either placebo or FRG three times per day for 4 weeks. Fasting and postprandial glucose profiles during meal tolerance tests were assessed before and after the intervention.
Compared to the placebo, FRG supplementation led to a significant reduction in postprandial glucose levels and to an increase in postprandial insulin levels. There also was a significant improvement in the area under the curve (AUC) in the FRG group. However, fasting glucose, insulin, and lipid profiles did not differ from the placebo group.
The authors of this trial concluded that daily supplementation with FRG lowered postprandial glucose levels in subjects with impaired fasting glucose or type 2 diabetes.
What should we make of these findings? Do they indicate that FRG might be an alternative to conventional anti-diabetic drugs? I would caution that we have tons of data for the latter, while we know far too little about FRG to recommend it for routine use.
On the contrary, the findings could suggest that diabetic patients who are well-controlled with diet or anti-diabetic medication should be avoiding ginseng products. If they actually work, they might significantly interfere with their metabolic control which, in turn, could even endanger their lives.
