Is an East Asian healing technique. Gua means to scrape or rub. Sha is a ‘reddish, elevated, millet-like 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.
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.A soupspoon, coin, or slice of water buffalo horn can be used.
