What Is Gua Sha?

Gua Sha is part of Traditional Chinese Medicine (TCM). Although it began in China, it spread throughout Asia and eventually to the West. Sometimes it is referred to as Chinese ‘folk’ medicine because people practice it on themselves as a sort of first aid. It is so commonly used that it is not taught in medical school. Gua Sha is the Chinese equivalent of chicken soup.

Gua means ‘to rub’ and sha refers to the red marks on the skin that appear after a treatment. To be specific, lotion may be applied to the area to be treated and a smooth tool is repeatedly scraped against the skin.

Traditionally the tool is made of a natural material like Water Buffalo Horn, ceramic spoons, or jade. Nowadays some tools are plastic or metal, but the main requirement is for it to be thin and have a rounded edge so it does not break the skin.

In Vietnam, the practice is called ‘Cao Gia’. It is performed by rubbing a coin against the back, chest, head, neck, or shoulders. It’s interesting to note that during the 1970s the telltale red marks on Vietnamese-American children were thought to be the result of child abuse, and some parents were mistakenly arrested.

To the untrained eye, ‘sha’ may look like road rash or a bicycle scrape, but the skin has not been bruised. No veins, capillaries, or arteries have been broken.

During the treatment, the body's meridians begin clearing and trapped pockets of fluid (lymph, lactic acid, blood) from a previous injury raise to the surface. Westerners are always surprised when the patient feels better but looks worse.
