The benefits of Gua Sha are numerous. It moves stuck blood, promoting normal circulation to the muscles, tissues, and organs directly beneath the surface treated. The patient experiences immediate changes in stiffness, pain, and mobility. Normal metabolic processes are restored by the movement of fluids as nutrients are carried to the tissues and metabolic wastes are carried away. Because Gua Sha mimics sweating, it resolves fever.
Gua Sha cools the patient who is overheated, warms the patient who is chilled, nourishes the patient who is deficient, and clears heat from the patient experiencing a feeling of excessive heat, internally or externally. Gua Sha is therefore considered an adaptogenic technique.
A care provider considers Gua Sha in any case of pain or discomfort, for upper respiratory or digestive problems, and for any condition where palpation indicates there is sha.
After Gua Sha, the patient is instructed to cover the area, avoiding wind and exposure to the sun, or sudden change in temperature. Stretching is recommended but not a heavy workout on the day of treatment.
