Reiki is a pseudoscientific form of energy healing, a type of alternative medicine originating in Japan. Reiki practitioners use a technique called palm healing or hands-on healing through which, according to practitioners, a "universal energy" is transferred through the palms of the practitioner to the client, to encourage emotional or physical healing. It is based on qi ("chi"), which practitioners say is a universal life force, although there is no empirical evidence that such a life force exists.
