Abstract:Objective: To observe the clinical effect of modified Danggui Sini tang for Raynaud's disease.Methods:Divided 96 cases of patients with Raynaud's disease randomly into two groups,48 cases in each group.The control group receivedsustained-release nifedipine for treatment,while the observation group received modified Danggui Sini tang for treatment.After one course,observed the clinical effect and changes of peak values of finger artery blood during systole of both groups before and after treatment.Results:The total effective rate was 85.4%in the observation group and was 54.2%in the control group,the difference being significant(P<0.05).After treatment,peak values of finger artery blood during systole were improved in comparison to those before treatment, differences being significant(P <0.05), and the improvements were more evident in the observation group,the difference being significant(P<0.05).Conclusion:Modified Danggui Sini tang has significant clinical effect on treating Raynaud's disease,which is worth of clinical application.
