homeopathyHomeopathy is a system of medicine basked upon the law of similars; like cures like.  A homeopathic remedy is simply a dilusion of one or several botanical, mineral, or animal substances that create a gentle means of stimulating the body's innate healing abilities.  

For example, everyone is familiar with the results of drinking too much coffee-shaky hands, jittery nerves, and insomnia.  Coffea cruda, a homeopathic remedy made from unroasted coffee beans, is used to alleviate these very symptonms, whatever the cause.  Like cures like.
