Gua Sha is a pain-free, instrument aided, soft tissue mobilization technique in which a tool is scraped over the skin to remove blood stagnation in the surface tissues of the skin. By disturbing the surface of the skin, stagnant blood is brought to the surface and new nourished blood is directed to the deeper tissues of the body including muscle tissue and fascia. Gua sha helps to decrease pain, and increase movement and flexibility in muscle tissue. Gua sha originated in eastern and southeastern Asia and has been used for centuries as a home remedy to treat everything from fevers and headaches to body aches and pains.
