The Society of Homeopaths has achieved PSA accreditation. Andy Lewis explains at:
This accreditation purely about being competent to keep a registrar. It is not about efficacy of homeopathy. But Andy is right. Perception is everything, and the public need to be made more fully aware that homeopathy is junk (that placebo is at play), and that PSA accreditation actually has no bearing whatsoever with regard to medical treatments.
