This practice of strategically “scraping” body surfaces is performed to relieve pain, reduce inflammation, increase circulation, and boost the immune system. Traditionally this is done with a small, flat jade stone with rounded edges, which can be used on the body, muscles, acupressure points, and/or meridians to release heat, toxins, and so on. You usually scrape in the direction of the meridians only until you see small red dots (called petechia). These red dots indicate that blood has been brought to the surface of the skin, where it is able to release the heat and toxins. Chinese medicine calls this “raising the sha,” which is said to eliminate stagnation and inflammation in the blood and protect the immune system for days or even weeks after the treatment. You can easily learn to do this at home for certain conditions, such as when you are feeling vulnerable to a cold, have tight or sore muscles, or are feeling inflamed in a particular part of your body. For chronic conditions such as cancer or autoimmune disease, or if there are lumps, cysts, or fibroids, I recommend working with a practitioner before performing gua sha.
