Pseudomedicine refers to "treatments that claim to be working concepts of medicine that have no objectively verifiable benefit or are incompatible with the current state of knowledge in the field of science-based medicine."[1] Historically, the term was used in the early 20th century by the American Medical Association when, as part of the effort to gain establishment status, it combated what it called quackery and pseudomedicine, thus differentiating itself as a professional organization of experts distinct from charlatan practitioners.[2]
