MG
Max Gerson
Max Gerson was a German-born American physician who developed the Gerson therapy, a pseudoscientific dietary-based alternative cancer treatment that he falsely claimed could cure cancer and most chronic, degenerative diseases. Gerson therapy involves a plant-based diet with coffee enemas, ozone enemas, dietary supplements, and raw calf liver extract; the latter was discontinued in the 1980s after patients were hospitalized for bacterial infections.
