Gua sha is a healing technique of traditional East Asian medicine. Sometimes called ‘coining, spooning or scraping’, Gua sha is defined as instrument-assisted unidirectional press-stroking of a lubricated area of the body surface to intentionally create transitory therapeutic petechiae called ‘sha’ representing extravasation of blood in the subcutis.
Modern research shows Gua sha produces an anti-inflammatory and immune protective effect that persists for days following a single Gua sha treatment. This accounts for its effect on pain, stiffness, fever, chill, cough, wheeze, nausea and vomiting etc., and why Gua sha is effective in acute and chronic internal organ disorders including liver inflammation in hepatitis.
