Guasha (pronounced gwahshah) is a cleansing technique used by many practitioners of traditional medicines. In guasha, the practitioner uses a stroking action to methodically apply pressure to the skin with a specialised round-ended instrument. This technique causes small red or purple spots (petechiae) called 'sha' to appear. The skin is not damaged in any way and the redness fades in a few days.

Guasha is used to move blocked "qi" (energy), which is considered to be the main cause of pain and stiffness in muscles and joints.

Guasha is a specialist technique and is contraindicated in certain cases. The easiest way to ensure your practitioner is properly trained is by visiting a British Acupuncture Council (BAcC) member.
