The body’s fear of wind and cold may be due to deficiency of the exterior surface (weakness of the muscle surface leading to abnormal sweating out) or deficiency of yang qi. In the case of deficiency of the surface, it is mostly due to the weakness of Wei Qi, which makes it easy for wind and cold to enter the body. The patient’s symptoms include sweating and bad wind, white color (white face without luster), and easy to catch a cold. Treatment can be Yuping Feng San to benefit the qi and consolidate the surface. Yang qi deficiency is characterized by weakness of Yang qi in the body or damage to Yang qi by disease. The patient manifests coldness, cold limbs, pale mouth without thirst, or like hot drinks, or self-sweating (involuntary sweating during the daytime, aggravated by sweating with a little movement), clear and long urine, or urine is unfavorable, thin stools, and a pale complexion. For treatment, Zaizaosan can be used to help Yang and Qi, and to relieve the surface and dispel cold (to get rid of the cold in the muscle surface). If the body is afraid of wind and cold, it is recommended to use under the guidance of a professional physician, not blindly self-medication.
