Medicine practised without scientific knowledge of a specific topic, but rather developed over a long period of time, usually centuries, by inhabitants of an area. Most folk medicine consists of herbal remedies for a disease. Some folk medicine is therefore beneficial, while some can be quite dangerous, or, if not practised properly, possibly fatal. This is not to say that these remedies don't work, because in many cases, they may. When considering folk medicine, use common sense and good judgement, and always consider the source.
