Radionics is an alternative medicine that claims disease can be diagnosed and treated with a kind of energy similar to radio waves. The concept behind radionics originated in the early 1900s with Albert Abrams (1864–1924), who became a millionaire by leasing radionic machines which he designed himself. Radionics contradicts some principles of physics and biology and, as such, is widely considered pseudoscientific. The United States Food and Drug Administration does not recognize any legitimate medical uses for radionic devices.
