The Law of Similars has been known since at least the time of Hippocrates (ca. 400 B.C.), but it was Samuel Hahnemann who fully stated the ideas of homeopathy in the early 1800’s. He was a doctor and a chemist in Germany who lived from 1755 to 1843. 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 had become relatively unknown in this country until recently.
