Prof.YU Jianer follows the characteristic of "children are Yang Qi-rooted

needing exact syndrome differentiation and resolute medication"of Xu’ s pediatrics

and treats infantile asthma from three-stage sequences.Prof.YU advocates descending Qi and resolving phlegm to relieve asthma in acute attack stage

resolving phlegm and invigorating spleen to consolidate the effect in the chronic persistent stage

as well as invigorating spleen and expelling phlegm to shake the root cause in the remission stage.Moreover

dispelling stasis and regulating Qi should be used through the whole treatment.Maintaining vital Qi is always significant during medication.Three-stage treatment takes treating asthma as the key link

and treating fluid as the constant.Even regulating lung-spleen

dissipating blood stasis and strengthening vital Qi are used at the same time.
