Patients with Blood Cold may experience symptoms such as cold hands and feet, purplish skin color, and numbness and pain in the limbs. Blood Cold is usually caused by external exposure to cold, which causes the body’s blood to stagnate and run sluggishly. When blood circulation functions abnormally and fails to moisten the tissues of the body, symptoms such as cold hands and feet, numbness of the limbs, a preference for warmth and aversion to cold, and a purplish complexion may occur. If cold condensation and blood stasis occurs, according to the theory of Chinese medicine, “if you don’t get through, you get pain”, there may also be pain in the limbs. At this time, the patient’s tongue is mostly characterized by purple dark tongue with petechiae. If you have any of the above discomforts, it is recommended that you go to a regular hospital for consultation and treatment under the guidance of a professional physician.
