After gua sha, the appearance of red skin often indicates poor blood circulation in the body. Gua sha effectively unblocks meridians, enhances blood flow, and thereby improves circulation and internal bodily conditions. The redness of the skin is a visible sign of gua sha's effect, indicating not only significant relief from heat toxins or blood stasis but also that the expected therapeutic outcome has been achieved. This is a positive bodily response, demonstrating that the gua sha technique was appropriate and effective. When skin turns red following gua sha, patients need not worry excessively; instead, they should maintain an optimistic attitude and continue treatment to promote recovery of health.
