A part of healing from ancient times. The induction of trance states and the use of therapeutic suggestion were a central feature of the early Greek healing temples, and variations of these techniques were practiced throughout the ancient world.Modern hypnosis began in the eighteenth century with Franz Anton Mesmer, who used what he called "magnetic healing" to treat a variety of psychological and psychophysiological disorders, such as hysterical blindness, paralysis, headaches, and joint pains.
