Urticaria is called “addiction rash” in Chinese medicine, and the difference between wind-heat type and wind-cold type is mainly judged by clinical manifestations. 1. Wind-heat type: mostly seen in acute urticaria, manifested as the whole body or the exposed parts of the air ball like rash, slightly above the skin surface, red or pink, itching, headache, fever, thirst, dry stools, urinating red, etc., tongue red, thin yellow moss or yellow greasy, pulse slippery. 2. Wind-cold type: mostly seen in chronic urticaria, manifested as a generalized pinkish-white or pinkish-red rash, itchy, aggravated by wind and cold, or with fever and cold (cold), no sweat, body pain, thirst, etc., with white moss, pale or red tongue, and floating tight pulse. The difference in etiology and clinical manifestations is the main difference between the two, and different treatments should be carried out according to their different clinical manifestations. It is recommended that patients with symptoms of urticaria seek medical attention as soon as possible, so as not to delay the condition and cause physical discomfort.
