Homoeopathy is a system of medicine based on the principle that like cures like; that the remedy which will cure the patient is the one that has the same effect on people as does the disease. There are many ways of seeing this process but one of the simplest is an assumption that the body knows what it is doing and medicine should help it rather than hinder it. Thus a person with a fever has a fever because it is the process the body uses to combat disease and infection. Conventional medicine often tries to reduce the fever even when it is not life threatening and so often negates the body’s own healing actions. Homoeopaths would give a remedy like Belladonna, which is made from the Deadly Nightshade, a poisonous plant that causes severe fever like symptoms if it is eaten.
