Gua Sha: a metal or ceramic tool is rubbed across the surface of the skin to free adhesions (layers of tissue that are fused together causing pain and dysfunction) and to increase blood flow.
The instrument is stroked across lubricated areas of the body at gently increasing levels of pressure. A traditional Chinese healing method, Gua Sha is believed to help blood flow, lessen toxins in the body and promote pain relief and healing. The stroking motion raises small, temporary rash-looking dots under the skin known medically as petechiae.
Gua Sha can be effective for chronic pain, inflammation, muscular pain, and tightness. Applied to specific areas of the neck, shoulders, and back, Gua Sha can stimulate the lymphatic system and the immune system to improve overall health.
