Objective To observe clinical effects of HE Puren’ s Three-Dredging Methods of acupuncturemoxibustion on simple obesity with splenic asthenia and accumulation of dampness syndrome. Methods Eighty patients suffering from simple obesity with splenic asthenia and accumulation of dampness syndrome were divided into moderate dredging method + srong dredging method + warm dredging method group（ 30 cases）

moderate dredging method + srong dredging method group（ 25 cases）

and moderate dredging method + warm dredging method group（ 25 cases）. The courses of the treatment in each group were 6 weeks. Clinical effects on patients in each group were observed after the six-month treatment finished. Standard body weight and body mass index（ MBI） of patients in each group before and after treatment were compared

and clinical effects were evaluated. Results Clinical effect in moderate dredging method + srong dredging method + warm dredging method group（ 90. 00%） was superior to that in moderate dredging method + warm dredging method group（ 68. 00%

P < 0. 05）

but with no statistical significance when it compared with that in moderate dredging method + srong dredging method group（ 76. 00%

P >0. 05）. Standard body weight of patients in each group all remarkably decreased after treatment（ P < 0. 05 or P <0. 01）; MBI of patients in moderate dredging method + srong dredging method + warm dredging method group remarkably decreased after treatment（ P < 0. 05）. Standard body weight and MBI in moderate dredging method +srong dredging method + warm dredging method group after treatment remarkably decreased compared with that in moderate dredging method + warm dredging method（ P < 0. 05）

but with no significant difference compared with that in moderate dredging method + srong dredging method group（ P > 0. 05）. Conclusion He’s Three Dredging Methods of acupuncture-moxibustion can reduce body weight of patients with simple obesity

and the moderate dredging method + srong dredging method + warm dredging method combination group is most effective.
