替代医学
The history of alternative medicine refers to the history of a group of diverse medical practices that were collectively promoted as "alternative medicine" beginning in the 1970s, to the collection of individual histories of members of that group, or to the history of western medical practices that were labeled "irregular practices" by the western medical establishment. It includes the histories of complementary medicine and of integrative medicine. "Alternative medicine" is a loosely defined and very diverse set of products, practices, and theories that are perceived by its users to have the healing effects of medicine, but do not originate from evidence gathered using the scientific method, are not part of biomedicine, or are contradicted by scientific evidence or established science. "Biomedicine" is that part of medical science that applies principles of anatomy, physics, chemistry, biology, physiology, and other natural sciences to clinical practice, using scientific methods to establish the effectiveness of that practice.
