Gua sha is the practice of using a tool to apply pressure and scrape the skin to relieve pain and tension. This action causes light bruising, which often appears as purple or red spots known as petechiae or sha. The name gua sha — pronounced gwahshah — comes from the Chinese word for scraping.
Gua sha is a natural, alternative therapy that involves scraping your skin with a massage tool to improve your circulation. This ancient Chinese healing technique may offer a unique approach to better health, addressing issues like chronic pain.
