Objective：To observe the clinical effect of Heye Jiangzhi tang for obesity of phlegm-dampness stagnation type.Methods：Divided 80 cases of patients with obesity of phlegm-dampness stagnation type into 2 groups randomly according to the order of hospitalization，40 cases in each group.Both groups receivedthe routine therapy，while the observation group additionally received Heye Jiangzhi tang for treatment.The course of treatment for both groups lasted for 60 days.Compared the changes of indexes including body mass index(BMI)，obesity degree(A)and body fat percentage(F)and the clinical effect of the two groups after treatment.Results：The clinical effect of both groups was compared，and the total effective rate was 72.50%in the control group and 97.50%in the observation group，difference being significant(P＜0.05).After treatment，BMI，A and F in both groups were compared with those before treatment，differences being significant(P ＜ 0.05)；after treatment，BMI and A in the observation group were compared with those in the control group，differences being significant(P ＜ 0.05)，and the observation group was better than the control group.Conclusion：Heye Jiangzhi tang has significant clinical effect in treating obesity of phlegm-dampness stagnation type，and can improve body mass index，obesity degree and body fat percentage.
