Objective To observe therapeutic effects of compounded zedoary turmeric oil suppository com-bined with microwave therapy on cervical erosion. Methods Women with cervical erosion were randomly divided in-to two groups: single microwave therapy group (control group) and compounded zedoary turmeric oil suppository com-bined with microwave therapy group (observation group). The chnical cure rate, obvious effective rate and ineffective rate were compared between two groups. Results In mild erosion, the clinical cure rate, obvious effective rate and ineffective rate were 87.8%, 12.2% ,0 respectively in the observation group. In tbe control group were 85.7%, 14.3%,0 respectively, and there was no significant difference between them (P >0.05); In moderate erosion, were 86.1%, 12.8%, 1.2% respectively in the observation group; were 60.9%, 31.9%, 7.2% respectively in the control group and there was significant difference between them (P < 0.01); In severe erosion, were 59.4%, 34.4%, 6.2% respectively in the observation group; were 29.17%, 41.7%, 29.2% respectively in the control group, and there was significant difference between them (P < 0.05). Conclusion Single microwave therapy to the mild erosion was suf-ficient; nevertheless, compounded zedoary turmeric oil suppository combined with microwave therapy to moderate and severe erosion was better than single microwave therapy.
