Jade Stones can be heated or cooled and are placed on or under the body as well as used directly for massage. This combines the benefits of hydrotherapy and thermotherapy. When using stones, the therapist can work deep into the muscle tissue to release muscle tension and localized pain without any discomfort. Chilled stones provide just as powerful of a massage as heated stones. When used together, it can create a feeling of a vascular flush to constrict and release blood vessels.
