Scraping is one of the traditional natural therapies in China. Based on the skin theory of traditional Chinese medicine, it scrapes the relevant parts of the skin with horns and jade to achieve the purpose of dredging meridians, promoting blood circulation and removing blood stasis. Scraping can dilate capillaries, increase sweat gland secretion, promote blood circulation, and have immediate effect on wind-cold arthralgia caused by hypertension, heatstroke and muscle soreness. Regular scraping can regulate menstruation, relieve fatigue and increase immune function.
