Prince Charles is a big supporter of “natural” medicine, which in practice means unscientific and ineffective medicine. He has no particular expertise in this area, and there is absolutely no legitimate reason why he should have any influence over the practice of medicine in the UK. But he is the Prince of Wales, and he has chosen to use that celebrity to promote CAM.
Prince Charles has also recently been criticized for his credulous support for medical nonsense. The Telegraph recently reported that Simon Singh, co-author with Edzard Ernst of Trick or Treatment, and exposer of CAM pseudoscience, spoke about Prince Charles at the recent Hay Festival in India. Singh had some sharp criticism, including:
He only wants scientific evidence if it backs up his view of the natural treatment of health conditions…
We presented evidence that disputes the value of alternative medicine and despite this he hasn’t changed his mind…
Singh’s point is that Prince Charles is Read more »

Media channels are a-twitter with the news that zinc can beat the common cold. CBS News, the LA Times, the Huffington Post, and hundreds of others are treating a quiet research report as big news that will have a life-changing effect. After reading the report and doing a little digging into the dark side of zinc, I’m not rushing out to stock up on zinc lozenges or syrup.
The latest hubbub about zinc was sparked by a report from the Cochrane Collaboration. This global network of scientists, patients, and others evaluates the evidence on hundreds of different treatments. In the latest review, on zinc for the common cold, researchers Meenu Singh and Rashmi R. Das pooled the results of 13 studies that tested zinc for treating colds. By their analysis, taking zinc within 24 hours of first noticing the signs of a cold could shorten the cold by one day. They also found that taking zinc made colds a bit less severe.
Sounds good so far. But instead of saying, “Hey, take zinc if you have a cold,” the researchers concluded like this:
“People taking zinc lozenges (not syrup or tablet form) are more likely to experience adverse events, including bad taste and nausea. As there are no studies in participants in whom common cold symptoms might be troublesome (for example, those with underlying chronic illness, immunodeficiency, asthma, etc.), the use of zinc currently cannot be recommended for them. Given the variability in the populations studied (no studies from low- or middle-income countries), dose, formulation and duration of zinc used in the included studies, more research is needed to address these variabilities and determine the optimal duration of treatment as well as the dosage and formulations of zinc that will produce clinical benefits without increasing adverse effects [bold is mine], before making a general recommendation for zinc in treatment of the common cold.”
Not exactly a ringing endorsement. Read more »

Does echinacea, the popular natural cold remedy, really work?
It depends on what you mean by “work.” Results [recently] reported in the Annals of Internal Medicine found that echinacea may reduce the length of a week-long cold by 7 to 10 hours and make symptoms a little less onerous. That can’t be characterized as a major effect, so many people may figure that the trouble and expense of echinacea just isn’t worth it (fortunately, side effects from echinacea don’t seem to be much of an issue.)
But others may decide that some benefit is better than none, and these results do fit with others that have left the door slightly ajar for echinacea having some effect as a cold remedy — a modest effect, but an effect, nonetheless.
A summary for patients published by the Annals summed up the situation nicely:
People who take echinacea to treat colds may experience a decrease in the length and severity of their cold symptoms but to such a small degree that they may not care about the difference. Although many studies of echinacea have been performed, researchers still disagree about its benefits in treating the common cold. This study is unlikely to change minds about whether to take this remedy.
Have you tried echinacea as a cold remedy? Has it worked? How do research findings, pro and con, affect your opinion of so-called alternative medicines?
Many of the echinacea studies, especially early on, were sponsored by companies making or selling the product. This study was supported by a grant from the National Center for Complementary and Alternative Medicine, which is part of the National Institutes of Health.

A spa in California is offering vaginal steam baths, in which spa-goers squat or sit on open stools over a tub of hot steam, as a cure-all for menstrual, digestion, and mood disorders:
The V-Steam: Inspired by an ancient ritual practiced for many years in Korea. The steam from the herbal tea rises and absorbs into your skin & orifice. This steaming treatment stimulates the production of hormones to maintain uterine health, aids regular menstrual cycles, helps correct digestive disorders while soothing the nervous system. The natural antibiotic and anti-fungal properties are said to help maintain internal health as well as keeping your skin looking young. (30 min: $50. Series of 6: $180.)
It’s a douche, folks. A $50 douche made with mugwort and 13 other herbs and having a fancy Korean name: Chai-Yok. True, the water gets up there as steam, and if you don’t squat just right over the steam bath, I imagine it may not get up there at all. But in the end, it’s a douche.
We docs strongly advise against douching since we know that women who do it have higher rates of vaginal and pelvic infections. Not to mention that the vaginal mucosa is highly-absorptive surface, meaning anything you put in there is likely to end up in the rest of your body. And so I ask: What herbs are they using, at what doses, and what side effects might they have? Not to mention what might be growing in those wooden tubs they have you squatting over? Read more »

Trying to keep up with what’s hot in skincare is like trying to keep up with the Kardashians. It’s impossible (not that I’ve tried with the Kardashians, that is.)
Then how are you to know what are the latest and greatest ingredients? Well, you could read The Derm Blog (when I get around to posting on it), or you could just listen to your grandmother.
Some of the newest discoveries in skin care aren’t new at all: Olive oil may be seem hot now, but countless Mediterranean grandmothers, including mine, have sworn by its skin-care benefits for centuries (millenia?) Were they right?
Olive oil contains caffeic acid, oleic acid, and oleuropein — all of which are potent antioxidants. Unlike berries or teas, these antioxidants are already in oil, allowing them to be directly applied to the skin. Topically applied olive oil helps dry skin, rosacea, psoriasis, seborrhea, burns, atopic dermatitis, contact dermatitis, diaper dermatitis, hand dermatitis, and eczema. Read more »
