Abstract：Chronic tonsillitis is one of common diseases in paediatrics．In normal conditions the disease is hard to cure and effect normal healthy life and study of Children．Therefore,clinical pediatric workers often pay attention to the effective prevention and treatment of this disease. Professor Chen Zhu proposes that base on the theory of latent pathogenic discuss about disease cause and mechanism of pediatric chronic tonsillitis，and considers that pediatric chronic tonsillitis and constitution of children are closely related．Latent pathogenic is an important pathogenesis of the disease. Latent evil make pediatric chronic tonsillitis happened which phlegm, heart and stasis remain dormant in the tonsil biosocially on the premise of deficiency body. The attack of this disease are "spontaneouse attack by latent pathogen"and"the disease induced by the pathogen once again".General therapeutic principle is opening onto pleurodiaphragmatic interspace and strengthening vital qi.However,flexibly grasp the degree between dispelling evil and reinforcing healthy qi that is the key to cure the disease, in the clinical treatment. The therapeutic principle of latent phlegm pathogen is expectorant by opening onto pleurodiaphragmatic interspace and dispersing swelling by strengthening spleen. The therapeutic principle of latent heat pathogen is the excess syndrome by clearing heattoxicity and the cases of deficiency by nourishing yinclearing heat. The therapeutic principle of latent stasis pathogen is activating blood removing and dispersing swelling by dredging collaterals.
