Homeopathy is a system of medicine based on the theory of "like cures like" - a poison that causes symptoms of illness in a healthy person can treat the same symptoms in someone who is ill. Substances are diluted many times to make a remedy that is safe to use, yet homeopaths believe sufficient "likeness" remains between the remedy and the illness to stimulate the body's self-healing attributes. Homeopathy is one of the most popular complementary therapies.
