jones_supa writes: Homeopathy is a 200-year-old form of alternative medicine based on the principle that substances that produce symptoms in a healthy person can be used to treat similar symptoms in a sick person. The National Health and Medical Research Council of Australia has officially declared that homeopathic remedies are useless for human health. The body will today release a guide for doctors on how to talk to their patients about the lack of evidence for many such therapies. Doctors will also be told to warn patients of possible interactions between alternative and conventional medicines. On top of that, the council has produced a 300-page draft report that reviews the evidence for homoeopathy in treating 68 clinical conditions. It concludes 'there is no reliable evidence that homoeopathy is effective for treating health conditions'. Representing the opposite viewpoint, Australian Homeopathic Association spokesman Greg Cope said he was disappointed at the narrow evidence relied on by the NHMRC in its report. 'What they have looked at is systematic trials for named conditions when that is not how homeopathy works,' he said. Homeopathy worked on the principle of improving a person's overall health and wellness, and research such as a seven-year study conducted in Switzerland was a better measure of its usefulness, he added. There are about 10,000 complementary medicine products sold in Australia but most consumers are unaware they are not evaluated by the domestic medicines safety watchdog before they are allowed on the market.
