Guasha "Scrape Sand" in Chinese (more loosely, "to scrape away disease by allowing the disease to escape as sandy-looking objects through the skin"), is a traditional therapeutic method existing in China since the oldest times.
It involves palpation and cutaneous stimulation where the skin is pressured, in strokes, by a round-edged instrument; that results in the appearance of small red petechiae called “sha”.
As many traditional medical practices, Guasha was doubtless practiced as a popular technique for a long time before it appeared in the first manuscript which mentioned it dating back approximately 700 years ago as for Chinese tradition.
