What Is Gua Sha?
Gua Sha is an East Asian healing technique. Gua means to scrape or rub. Sha is a ‘reddish, elevated, skin rash’ (aka petechiae). Sha is the term used to describe Blood stasis in the subcutaneous tissue before and after it is raised as petechiae. Gua Sha is one technique that intentionally raises Sha rash or petechiae. Gua Sha is used whenever a patient has pain whether associated with an acute or chronic disorder. There may be aching, tenderness and/or a knotty feeling in the muscles. In addition to resolving musculo skeletal pain, Gua Sha is used to treat as well as prevent common cold, flu, asthma, as well as any chronic disorder involving pain, congestion of Qi and Blood. Sha is raised primarily at the Yang surface of the body: the back, neck, shoulders, buttocks, and limbs.
On occasion, Gua Sha is applied at the chest and abdomen. The area to be Gua Sha-ed is lubricated with oil. The skin is then rubbed with a round-edged instrument in downward strokes. One area is stroked until the petechiae that surface are completely raised. If there is no Blood stasis the petechiae will not form and the skin will only turn pink. For lubrication I use a special massage oil. Thick oil such as peanut oil was used traditionally. A soupspoon, coin, or slice of water buffalo horn is used in Asia. The color of the Sha is both diagnostic and revealing. Very light colored Sha can indicate Deficiency of Blood. If the Sha is fresh red, it is of recent penetration. If the Sha is purple or black, the Blood stasis is long-standing. If brown, the Blood may be dry. Dark red Sha can indicate heat.The Sha petechiae should fade in 2-4 days. In most cases the patient feels an immediate shift in their condition particularly in their pain or sense of constraint.
Gua Sha moves stuck Qi and Blood, releases the Exterior mimicking sweating, and moves Fluids. In a modern medical construct these fluids contain metabolic waste that congested the surface tissues and muscles. Gua Sha promotes circulation and normalizes metabolic processes. It is a valuable treatment for both external and internal pain, and facilitates the resolution of both acute and chronic disorders. Gua Sha is a completely safe technique, but knowing when to use it and what to expect from treatment is as important as good technique. It is good to be moderate in activity after treatment, even rest. I have always told my patients after treatment: no drugs, booze, sex, fasting, feasting or hard labor, including working out, for the rest of the day. In other words, relax.
