Bright red marks appearing after back gua sha often indicate that the patient has a relatively severe internal condition of damp-heat. Since the back is a key area where the body's yang energy gathers, excessive damp-heat can be effectively addressed through gua sha—a traditional therapy that stimulates the skin and promotes blood circulation, helping the body expel excess moisture and toxins. The redness following gua sha is a visible sign of this process, demonstrating that the treatment is working as intended. Patients need not worry, as this reaction is normal during therapy. However, after gua sha, it remains important to stay warm and avoid re-exposure to dampness to ensure the therapeutic effects are properly consolidated.
