Asia is popular with traditional healing and medication practice. One of them is Gua Sha. It is commonly used by folks that chose not to seek treatment with doctors and prefer to treat themselves with alternative methods of treatment.
It is considered to be more of a “folk therapy”. Folks do not mean to be used in any pejorative sense but to emphasis on people who are able to do for themselves in the comfort of their homes or in monasteries.
It is a traditional treatment similar to massage and acupuncture that helps getting rid of common ailments. However, Gua Sha is less known in the west comparatively.
