What amazes me is that there is official funding for homeopathic remedies and even hospitals (!) in the British healthcare system, the NHS.
I applaud the NHS for issuing a strongly-worded statement about homeopathy. Perhaps they are still smarting over the Wakefield MMR autism scandal, and looking for low-hanging fruit to go after.
Homeopathy is founded on several non-rational tenets such as the law of similars, and the concept of "miasms."
I have had people take hyperbaric oxygen therapy for foot ulcers with some success, but otherwise had no idea these things were being used to treat cancer, AIDS, and other illnesses. The Cochrane Review looks to be gearing up to review the use of ozone in diabetic foot ulcers soon, stay tuned for some of their usually definitive coverage.
Doctors purveying questionable therapies: if you're not careful, the FDA will sic the US Marshals on you!
