It is considered that the lesion of pediatric lip wind is located in the lip, the disease originates from the spleen and stomach, and the pathogenic factors are related to wind, fire, dryness and dampness. Clinical diagnosis and treatment of pediatric lip wind can be divided into three phases and four syndrome types according to the exuberance and decline of pathogenic and healthy qi and changes of excess and deficiency and different symptom profiles. In the acute initial phase with redness, swelling, pain and itching as the main manifestation, the pathogenesis is heat accumulation in spleen and stomach, and wind and fire attacking upwards, the treatment should be to clear stomach and purge spleen, disperse fire and eliminate wind, and modified Xiehuang San combined with Qingwei San should be used. In the chronic persistence stage with eczema vesicles as the main manifestation, the pathogenesis is dampness heat in spleen and stomach, and wind-damp-heat accumulation, the treatment should be to clear heat and protect yin, dispel dampness and eliminate wind, and modified Xiaofeng San should be used; while when dryness and desquamation are the main manifestation, the pathogenesis is deficiency heat in spleen and stomach, and blood dryness generating wind, the treatment should be to nourish yin and purge fire, nourish blood and eliminate wind, and modified Siwu Xiaofeng Yin should be used. In the remission and recurrence stage with mild symptoms and easy recurrence as the main manifestation, the pathogenesis is latent wind in the spleen and stomach, and dryness and dampness being retained, the treatment should be to promote the middle-jiao and eliminate wind, moisten dryness and resolve dampness, and modified Zengye Tang should be used.
