Although scorned in the early 1900s and publicly condemned by Abraham Flexner and the American Medical Association, the practice of homeopathy did not disappear. Instead, it evolved with the emergence of holistic healing and Eastern philosophy in the United States and today is a form of alternative medicine practiced by more than 100,000 physicians worldwide and used by millions of people to treat everyday ailments as well as acute and chronic diseases.

The History of American Homeopathy traces the rise of lay practitioners in shaping homeopathy as a healing system and its relationship to other forms of complementary and alternative medicine in an age when conventional biomedicine remains the dominant form.
