Guasha is an ancient technique of using a tool and rubbing the tool along specified part of the body. This technique has also been known as coin rubbing and is still practiced by many cultures to this day. The tool is usually a glass spoon or a comb like tool (without the teeth) made of stone or bone. A small amount of salve is applied and then the guasha tool is then rubbed vigorously along the skin.
Guasha is a technique that essentially opens the pores of the skin. It also brings warmth and circulation to the area. Like cupping, guasha is often used to treat muscular pain as well as vent colds and flus. If you have ever seen someone who looks like they have strange red marks on the back of their neck or temples, this is more than likely the practice of guasha or coin rubbing. You can do this practice at home on yourself or family members!
