Gua sha (Chinese: åˆ®ç—§; pinyin: guÄ shÄ), literally "to scrape away fever" in Chinese (more loosely, "to scrape away disease by allowing the disease to escape as sandy-looking objects through the skin"), is an ancient medical treatment.
Sometimes referred to as "spooning" or "coining" by English speakers, it has also been given the descriptive French name, "tribo-effleurage".
The Vietnamese term for this practice is cáº¡o giÃ³ ( listen). This term translates roughly "to scrape wind", as in Vietnamese culture "catching a cold" or fever is often referred to as trÃºng giÃ³, "to catch wind". The origin of this term is the Shang Han Lun, a ~220 CE Chinese Medical text on cold induced disease - like most Asian countries China's medical sciences were a profound influence in Vietnam, especially between the 5th and 7th Centuries CE. Cáº¡o giÃ³ is an extremely common remedy in Vietnam and for overseas Vietnamese. There are many variants of Cáº¡o giÃ³. Some methods use oil balm and a coin to apply pressure to the skin. Others use a boiled egg with a coin inserted in the middle of the yolk. The egg is wrapped in a piece of cloth and rubbed over the forehead (in the case of a fever) and other areas of skin. After the rubbing, when the coin is removed from the egg, it will appear black.
It is also used in Indonesia. It is a traditional Javanese technique, known as kerikan (lit., "scraping technique") or kerokan, and it is very widely used, as a form of "folk" medicine, upon members of individual households.
