Like most of the techniques used in Chinese Medicine, Gua Sha has been used for thousands of years. Gua Sha, also known as “scraping therapy,” is a technique that involves repeated firm strokes over oiled skin with a special tool. The Gua Sha tool is fashioned out of ceramic, jade, or buffalo horn. During Gua Sha therapy, the surface of the skin is scraped along the meridian pathways to move qi and blood, remove toxins and blockages, promote healing, and eliminate pain.
