Objective： To observe the clinical effect of thorn sifeng combined with spleen-invigorating and phlegmresolving method for chronic cough in children.Methods：Selected 47 children with chronic cough，and divided them into the observation group and the control group randomly，25 cases and 22 cases in each group.The observation group was given thorn sifeng combined with spleen-invigorating and phlegm-resolving method，while the control group was given western medicine.After treatment of two weeks，observed the curative effect and incidence of adverse reaction.Observed the recurrence after follow-up of 3 months.Results：The clinical effect in the observation group was better than that in the control group，the difference being significant(Z=2.270，P=0.023).After treatment，the scores of cough frequency，cough after activity， phlegm and other Chinese medicine syndrome were lower than those before treatment in both groups，differences being significant(P＜0.05).The scores of each Chinese medicine syndrome in the observation group were lower than those in the control group，differences being significant(P＜ 0.05).Incidence of adverse reactions was 0 in the observation group and was 18.18%in the control group，the difference being significant(P＜0.05).After follow-up of 3 months，the recurrence rate was 11.11%in the observation group and 55.56%in the control group，the difference being significant(P＜0.05).Conclusion：The treatment of thorn sifeng combined with spleen-invigorating and phlegm-resolving method can effectively improve the symptoms and signs of children，less adverse reactions and low recurrence rate.
