Gua sha (Chinese: 刮痧), kerokan or coining is part of traditional Chinese medicine (TCM). Its practitioners use a tool to scrape people's skin to cause tissue damage in the belief this has medicinal benefit. Gua sha is sometimes referred to as "scraping", "spooning" or "coining" by English speakers. The treatment has also been called the descriptive French name, tribo-effleurage.
As reported by a review article in the Journal of the American Academy of Dermatology, the negative side effects of gua sha range from minor ones – including dermatitis, burns and hematuria – to rare major ones including cerebral hematoma and severe injuries requiring skin grafts.
Gua sha was transferred from China to Vietnam, where it became very popular. It is known as cạo gió, which roughly means "to scrape wind", as in Vietnamese culture "catching a cold" or fever is often referred to as trúng gió, "to catch wind". The origin of this term is the Shang Han Lun, a c. 220 CE Chinese medical text on illness caused by cold. As in most Asian countries, China's medical sciences were a profound influence in Vietnam, especially between the 5th and 7th centuries CE. Cạo gió is an extremely common remedy in Vietnam and for expatriate Vietnamese.
In popular culture
The 2001 movie The Gua Sha Treatment (Chinese: 刮痧; pinyin: guā shā) was made in Hong Kong and showed gua sha. It is a story about cultural conflicts experienced by a Chinese family in the United States.
