Using Convergent Color Doppler.CCD technology to observe the efficiency of TCM which has the effect of promoting the blood flow and vanishing and eliminating stagnation (Jiliu Neixiao pills).To explore the mechanism of clinical efficacy of Jiliu Neixiao pills.Methods：Blood flow of leiomyomas were divided into 0， I， Ⅱ， III grade by Convergent Color Doppler CCD.Sixty two patients were randomly divided into treatment group (n=32) and control group (n=30).Patients in the treatment group were given Jiliu Neixiao pills which were prescribed by Professor Xiao Chengzong; the control group gave patients Guizhifuling capsule treatment.The Convergent Color Doppler CCD was performed， the blood flow was observed before and after treatment respectively within twenty-four hours.The change of blood flow in leiomyomas was observed and the therapy effect of Jiliu Neixiao pills was evaluated.Results：Reduction of blood flow， vanishing of leiomyomas and curative effective of the treatment group were better than those of the control group .There was significant difference between the two groups (P<0.05).Conclusion：The Jiliu Neixiao pills posses a good ablation effect， and it is worth generalizing.
