Gua Sha loosely translates as 'scraping', where a tool is used to scrape the skin to relieve congestion. In Chinese Medicine, 'Where there is stagnation, there is pain.', is a commonly used phrase. Therefore, using gua sha is helpful in cases of muscle strain or spasm, where the area may not be getting proper blood and energy flow.
Gua sha is also very helpful to relieve the common cold, fever, stiffness, nausea, and even chronic internal organ disorders.
