Homeopathic formulae are based on the simple theory that if a substance will cause symptoms in a healthy person it will assist the curing of these symptoms in a sick person. Thus all homeopathic remedies are ‘proved’ by being given to healthy people to see what effects they have, eg coffee and onions alleviate insomnia and hay fever.
Remedies are created by being diluted with water in ever increasing amounts, even to the point where no starting material remains. This diluting, together with a process of succession or vigorous shaking, creates the remedies because as is hypothesised, the water retains a “memory” of what it was once in contact with. These remedies can assist the body to cure many illnesses.
