Homeopathic Medicine is meant to stimulate the body with very tiny (infintessimal) doses of a medicinal substance. Most homeopathic remedies are made from plant materials or medicinal substances that have or had been used for hundreds of years. All homeopathic medicines in the USA must be approved by the HPUS (Homeopathic Pharmacopea of the United States, they oversees manufacturing quality and safety.)
