Raionics is the use of blood, hair, a signature, or other substances unique to the person as a focus in order to supposedly heal a patient from afar. 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. However, Abrams was never able to demonstrate that his devices were effective; no radionic device has been found effective in the diagnosis or treatment of any disease, and the United States Food and Drug Administration does not recognize any legitimate medical uses for such devices.
