How to perform gua sha
Purchase a gua sha tool.
You can purchase a tool made specifically for gua sha therapy online or at alternative medicine stores. A gua sha tool is a rounded tool made of a smooth material like wood, stone, plastic, stainless steel, or jade.
Some gua sha tools look like smooth stones, while others are more elaborate and have handles. If you don't want to purchase a tool, you can use a rounded plastic spoon or the lid from a jar instead.
