Reiki is a therapy often described as palm healing or hands-on-body healing in which a practitioner places hands lightly on or over a patient's body to facilitate the patient's process of healing.
Reiki combines the Japanese and Chinese word-characters of "rei" (spiritual or supernatural) and "ki" (vital energy). One of the basic ideas held by those who practice Reiki is that this vital energy can be channeled to support the body's natural ability to heal itself, according to the National Center for Complementary and Integrative Health (NCCIH).
