What is Reiki?

Reiki is a spiritual practice developed in 1922 by Mikao Usui.

After three weeks of fasting and meditating on Mount Kurama, in Japan, Usui claimed to receive the ability of "healing without energy depletion".

A portion of the practice, tenohira or palm healing, is used as a form of complementary and alternative medicine (CAM).

Tenohira is a technique whereby practitioners believe they are moving "healing energy" through the palms.

There is no generally accepted scientific evidence for either the existence of ki or any mechanism for its manipulation, and a systematic review of randomized clinical trials conducted in 2008 did not support the efficacy of reiki or its recommendation for use in the treatment of any condition.

Although clients often describe pleasant side effects.
