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) Radionics contradicts some principles of physics and biology and, as such, is widely considered pseudoscientific. The United States FDA does not recognize any legitimate medical uses for radionic devices.
According to radionics practitioners, a healthy person will have certain energy frequencies moving through their body that define health, while an unhealthy person will exhibit other, different energy frequencies that define disorders. Radionic devices purport to diagnose and heal by applying appropriate frequencies to balance the discordant frequencies of sickness. Radionics uses "frequency" not in its standard meaning but to describe an imputed energy type, which does not correspond to any property of energy in the scientific sense.
