This paper introduced Professor WANG Lie′s clinical experience in the treatment of infantile asthma. According to the pathogenesis characteristics

infantile asthma was divided into attacking stage

remitting stage and stable stage for syndrome differentiation and treatment. It is believed that the attacking stage was dominated by exce-ssive pathogen of wind and stasis

so it was necessary to dispel wind and activate blood to stop asthma. The patient was given modified Pingxiao Decoction（平哮汤）

and supplemented with the antitussive and antiasthmatic products. In the remitting stage

it was mainly about lingering pathogen due to deficient vital qi. Purging lung and descending qi were used to relieve dyspnea

and invigorating spleen and tonifying kidney were used to resolve phlegm. Xiefei Decoction（泻肺方） and Huatan Decoction（化痰汤） were commonly used in the above. In the stable period

kidney qi was insufficient and phlegm qi was hidden

so benefiting qi to remove phlegm was used to consolidate body

and modified Gufang Decoction（固防汤） was applied.
