Crystal healing is a pseudoscientific alternative medicine technique that employs stones and crystals. Adherents of the technique claim that these have healing powers, although there is no scientific basis for this claim.

One method is where the practitioner places crystals on different parts of the body, often corresponding to so-called "chakras"; or else the practitioner places crystals around the body in an attempt to construct an "energy grid", which is purported to surround the client with healing energy.Despite this, scientific investigations have not validated claims that chakras or energy grids actually exist, nor is there any evidence that crystal healing has any greater effect upon the body than any other placebo.
