What does it mean when black-purple spots appear after gua sha (scraping therapy), and what should be done?

Generally, the appearance of dark purple spots on the body may be caused by blood stasis, thrombosis, purpura, vasculitis, or blood disorders. A detailed analysis is as follows:

1. Blood stasis: This refers to poor blood flow within blood vessels, leading to blood accumulation and the formation of dark purple spots. Treatment options include traditional Chinese therapies such as massage, gua sha, and cupping, which can promote blood circulation and resolve blood stagnation.

2. Thrombosis: Thrombosis occurs when a blood clot blocks a blood vessel, impairing circulation. Under medical supervision, anticoagulant medications such as aspirin tablets or heparin may be prescribed to prevent clot formation and expansion.

3. Purpura: Purpura is an autoimmune disease that causes purple spots on the skin. It is recommended to use immunosuppressive agents such as azathioprine or cyclosporine under medical guidance to reduce the immune system's attack on blood vessels.

4. Vasculitis: Vasculitis involves inflammation of the blood vessel walls, leading to vessel rupture and bleeding, which results in dark purple spots. Medications such as methylprednisolone tablets or prednisone acetate may be used under medical supervision to reduce inflammatory responses and protect the health of blood vessel walls.

5. Blood disorders: Certain blood diseases may cause dark purple spots on the skin. Treatment may involve supplementing deficient platelets or reducing excessive platelet counts to restore normal blood function.

If dark purple spots appear on the body, it is advisable to seek immediate medical attention for thorough examination and diagnosis. Appropriate treatment should be administered based on the specific underlying condition.
