Crystal healing philosophy taps into the traditional Asian concepts of life-energy (chi or qi) and chakras, which are vortices of this life-energy said to connect the physical and supernatural elements of the body.  Yet because crystal healing so often is incorporated into the practice of astrology, soothsaying and modern witchcraft, as well as the belief in reincarnation, intelligent extraterrestrial life and the lost city of Atlantis, even ardent proponents of alternative medicine tend to dismiss it as a useless therapy, if not ludicrous.

No studies have ever demonstrated any therapeutic value for crystal healing.  At a purely scientific level, there is no evidence that disease is caused by poor cosmic energy flow — positive or negative — or that crystals and gems can be differentiated by chemical composition or color to treat a particular ailment.
