MODEL RELEASED. Homeopathic medicine preparation. Time-exposure image of a pharmacist preparing homeopathic medicine by shaking it in a vial. The principle of homeopathy, founded by Hahnemann, is to cure symptoms of an illness by administering minute doses of substances responsible for those symptoms. Homeopathic remedies are prepared from plant, mineral and animal sources. Dosages are formulated through a series of dilutions. Homeopathy also requires the physician to treat the patient as a whole, rather than just the specific illness observed.
