"An investigation has revealed that every one of ten randomly selected homoeopathic clinics and pharmacies was willing to recommend its products as an alternative to proven prophylactic drugs, in defiance of advice from the Health Protection Agency….. Homoeopathy is controversial as there is no scientific evidence that it is effective. Remedies are created by diluting substances to an extreme degree, usually so not a single molecule of the main ingredient is left, and most scientists consider that its only medical value lies in the placebo effect. It is generally accepted that the remedies are not themselves dangerous, as they contain no chemically active ingredients, but they can put people at grave risk when used in place of medications that are needed to treat or prevent disease."
