Objective To observe the Fuyuan Tongluo decoction with the treatment of lower extremity venous insufficiency and blood stasis type resistance clinical effect. Selection. Methods 60 patients with venous insufficiency of lower limbs， were randomly divided into control group and treatment group 30 cases and control group taking away off check two pills each time， three times a day， the treatment group in the control group on the basis of taking the Fuyuan Tongluo decoction： safflower 1g， caulis spatholobi 3g， lulutong 3g， common clubmoss herb 3g， generation of tea， are 8 weeks treatment， observation of 60 cases of patients with lower limb venous insufficiency and blood stasis type resistance changes in symptoms， venous blood gas values change before and after medication. Results After treatment effective rate of treatment group： 93. 3%， control group after treatment effective rate：83. 3%；After treatment， the symptoms of two groups was obviously improved， the treatment group than the control group and fatigue symptoms improved more significantly（P<0.05）. In the two groups after treatment O2 saturation， O2 partial pressure improved， CO2 partial pressure， total CO2 partial pressure and PH value decreased， and the treatment group than the control group O2 saturation， O2 partial pressure improved more significantly（P<0.05）， the treatment group than control group in the CO2 partial pressure， total CO2 partial pressure decreased more significantly（P<0.05）. Conclusion The recover only strengthen party to improve lower limb venous insufficiency and blood stasis resistance model has good clinical effect， there is a certain relationship with blood gas values.
