The Law of Similars has been documented since at least the time of Hippocrates (ca. 400 B.C.), but it is Samuel Hahnemann (1755-1843), a German doctor and chemist, who is credited with founding homeopathy. He discovered the truth of the Law of Similars by testing small doses of medicine on himself.
By 1900, about twenty percent of doctors in the United States were homeopaths, but due to various political and social changes, homeopathy became relatively unknown in the US until recently. There is wider acceptance of homeopathy in such countries as France, Germany, Mexico, Argentina, India and Great Britain. In fact, the family doctor to England’s Queen Elizabeth is a homeopathic physician. In fact, the World Health Organization estimate that it is currently practiced by over 500 million people worldwide.
