Urticaria, known as “addiction rash” in Chinese medicine, is one of the common and frequent diseases in dermatology. The cause of this disease is complex. Modern medicine believes that it is related to the body’s allergic reaction to certain substances. In Chinese medicine, it is thought to be caused by “the deficiency of Qi where the evil comes from”, and it is easily recurring due to the stimulation of various factors, making the patient suffer. This skin disease requires persistent medication, while avoiding the stimulation of various factors in life, treating both the symptoms and the root cause, and fundamentally “supporting the righteousness and removing the evil” to change the constitution, in order to be cured. Usually the longer the onset of the disease, the longer the time to take medicine. The more time you have, the longer you have to take medicine, the longer you have to take medicine. You should pay attention to maintaining a regular lifestyle, strengthening physical exercise, enhancing physical fitness; avoid scratching the affected area strongly, not using hot water, not abusing strong topical medications; actively search for and remove the cause of the disease, adjusting gastrointestinal function, keeping the bowels open; avoid eating animal protein foods and seafood hair, not eating spicy and stimulating foods, not drinking alcohol, maintaining a light diet, eating more fresh vegetables and fruits.
