Urticaria is called “addiction rash” in Chinese medicine, and is characterized by the appearance of occasional raised red bumps on the skin with intense itching. Because of its rapid onset and recurrent occurrence of the rash, it is called addiction rash in traditional Chinese medicine. Western medicine belongs to allergic diseases, related to allergies. In recent times, the incidence of this disease has increased due to the increasing climate and environmental changes, air pollution, the widespread use of pesticides, antibiotics, food additives of various ingredients in the diet, and the allergenic effect of drugs of abuse. It is especially common in children. Western medicine treatment is based on anti-allergic and symptom relief, and commonly used anti-allergic drugs such as glyburide lotion, oral loratadine and cetirizine. According to Chinese medicine, the causative factors of this disease are mainly wind, and often heat, cold or damp. However, for some children with a long history of recurrent illness, accompanied by easy sweating, easy to catch a cold, poor appetite and weight gain or loss, the treatment should also take into account the root cause, such as adding Huang Qi or Yu Ping Feng San for children with Qi deficiency and Angelica Sinensis for those with Blood deficiency to nourish Blood and moisten dryness. During the period of illness and treatment, we should pay attention to a light diet, avoid eating hairy things such as straw mushrooms, shrimps and crabs, and have a regular routine. Avoid scratching the affected area as much as possible.
