Reiki (霊気 or レイキ, Reiki? IPA: [ˌreɪki]) is a form of spiritual practice, often compared to faith healing,[1][2][3] proposed for the treatment of physical, emotional, mental and spiritual diseases.[4][5][6] Mikao Usui developed Reiki in early 20th century Japan, where he said he received the ability of 'healing without energy depletion' after three weeks of fasting and meditating on Mount Kurama.[7] Practitioners use a technique similar to the laying on of hands as well as gestures in the air, which they say will channel "healing energy" (ki).[8] Practitioners state energy flows through their palms to bring about healing.

The majority of the scientific community considers Reiki to be pseudoscience[9] due in part to studies demonstrating Reiki as performing nothing more than the function of a placebo.[10]
