Gua Sha is another form of therapy which affects us through the actions and functions of the skin. A Chinese porcelain spoon is used in a manner to stimulate the skin and the underlying tissues, and hence the qi of the meridians through the acupoints. Used according to TCM practice to release fire from the meridians, this therapy has some similar applications to cupping. Blood is encouraged to flow more easily through the vessels, effecting a cleansing action on the body. Gua Sha breaks up solidifying waste products hiding in subcutaneous tissue, leaving these impurities in a state where excretion via perspiration or by reintroducing them to the bloodstream for excretion by the liver and kidneys is the result.
