ObjectiveTo observe the clinical effect of Maxing Zhisou tang for children with postinfectious cough of wind-phlegm type.MethodsDivided 60 cases of children with postinfectious cough of wind-phlegm type into the treatment group and the control group randomly，30 cases in each group.The treatment group was given oral Maxing Zhisou tang，while the control group was given montelukast sodium chewable tablets.After treatment，observed the improvements of cough and expectoration，and then evaluated the short-term and long-term therapeutic effect.ResultsAfter treatment，the scores of cough and expectoration were decreased when compared with those before treatment，differences being significant(P＜0.05).Scores of cough and expectoration in the treatment group were lower than those in the control group，differences being significant(P ＜ 0.05).After 7 days of treatment，the total effective rate was 90.0%in the treatment group and was 66.7%in the control group，the difference being significant(P<0.05).After 14 days of treatment，the total effective rate was 100%in the treatment group and was 73.3%in the control group，the difference being significant(P＜0.05).The recurrence rate was 6.7%in the treatment group and 27.3%in the control group，the difference being significant(P ＜ 0.05).ConclusionThe therapy of Maxing Zhisou tang for children with postinfectious cough of wind-phlegm type can effectively improve cough and expectoration.The clinical efficacy of the therapy is superior to that of montelukast sodium chewable tablets，and it has low recurrence rate.
