Gua sha is a traditional Chinese healing method that involves using a smooth-edged tool to stroke the skin while pressing on it. This motion raises small, red, rash-like dots that show under the skin called petechiae. People use gua sha to treat chronic pain all over their body, often alongside other complementary treatments like herbal medicine, massage, acupuncture, and heat therapy. To prepare for treatment, a technician will put oil on the body and then use the gua sha massage tool to scrape the skin in long, downward strokes. This process is believed to help blood flow and create a “lifting” effect on the skin, which some say may help lessen toxins in the body and promote healing. Gua sha is generally performed on the back, neck, butt, arms, and legs, and a gentle version of it is even used on the face as a facial technique. The benefits of gua sha are not well-established, but some studies suggest that it may help lower the amount of liver inflammation caused by the hepatitis B virus and reduce inflammation, relieve pain, and improve circulation. However, more research is needed to confirm these benefits. Gua sha is generally safe, but it may cause mild bruising and is not suitable for those with certain medical conditions.
