Raynaud’s disease, also known as arterial spasm of the extremities, is a frequent and common disease in winter in northern regions. In the cold environment, there will be cold hands and feet, cold limbs, followed by pallor, cyanosis, and finally redness and congestion to edema, pain and other symptoms. Unlike Raynaud’s phenomenon, which is a spasm of the arterial vessels of the fingers (toes), Raynaud’s disease is due to the involvement of arteries, even to the point of complete occlusion. Many diseases can cause it: scleroderma, dermatomyositis, lupus erythematosus, rheumatoid rheumatoid, vasculitis, etc., but most people with Raynaud’s disease don’t have any other lesions. Overcoming emotional changes is the key to preventing recurring symptoms. Western medicine generally uses vasodilators in treatment to relieve vasospasm and reduce the response of blood vessels to cold stimuli, but the treatment effect is generally less than ideal. In fact, the most common Raynaud’s phenomenon and Raynaud’s disease is the most suitable for the dialectical treatment of Chinese medicine, and the efficacy is satisfactory. Therefore, the ancients said: “the meridians are traveling to the hands and feet, the deficiency of blood and gas loss, can not warm its limbs, so the extremities against the cold also”.
