There's some trouble brewing in Tanzania.
Homeopath, Jeremy Sherr, has travelled to deepest, darkest Africa in search of fertile grounds in which to perform clinical trials on the effectiveness of homeopathic preparations on HIV+ patients who are not taking anti-retrovirals.
It seems he wasn't able to get a test protocol through ethics boards in Europe (and rightly so), so he's taken his show on the road to places where he can get away with murder - quite literally.
New readers might not be aware that homeopathy is a supersitious belief that water can be magically imbued with healing properties, in defiance of too many laws of physics to mention. I've already done a pretty telling demonstration on the complete lack of eficacy of homeopathic products (although not exactly a double-blind controlled study - others have done those).
What makes it even worse is that Sherr has been documenting his efforts on his blog. And when his statements came under scrutiny, he resorted to some historical revisionism to try and cover his tracks.
