Gua sha is a traditional East Asian medical treatment. It is frequently used to relieve muscle discomfort and stress, but research on its efficacy is lacking. We investigate if gua sha is effective and whether it has adverse effects. Gua sha tries to circulate qi or chi throughout the body. The therapy involves rubbing the skin in long strokes with a tool while providing sufficient pressure to cause slight bruising.
