Objective:To observe the Bufei granules in the treatment of asthma in remission stage effect.Method: Fourty-three cases of asthma patients in remission

were randomly divided into a treatment group（22 cases）

21 cases of the control group.The treatment group given Bufei particles

the control group was given Bufei particle simulation agent.Treatment for 1 month

followed up for 3 months.Observation: asthma symptoms integral

asthma control test（ACT） score

indices of pulmonary function

blood eosinophil count index.Using IBM SPSS Statistics 19 statistical analysis.Result: Traditional Chinese Medicine（TCM） syndrome scoring

the treatment group decreased obviously

compared with the control group（P<0.01） has significant difference;patients with ACT score

the treatment group increased significantly

（P<0.01） has significant difference;and can reduce the peripheral blood eosinophil count

and before treatment is compared to P<0.05

have the difference of statistics;improved peak expiratory flow（PEF）

with significant difference

（P<0.01）;reduce attack frequency.Conclusion: Bufei granules can obviously improve the symptoms of patients with bronchial asthma in remission stage

and improve lung function

reduce the level of eosinophils（EOS）

through the inhibition of airway inflammation

and to control the remission stage of bronchial asthma symptoms

reduce episodes of purpose.
