Gua sha:

Gua sha is a TCM healing modality, similar in effect and practice to Graston technique. Gua sha is 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 tiny purple or red dots called 'sha', which is the release of old static blood in the subcutaneous.

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.
