Methods Placebo-controlled randomized double-blind trial. 72 patients with chronic prostatitis were randomly divided into two groups. In the treatment group, 36 cases were treated with Qianliean suppository once a night for 1 month continuously. In the control group, 36 cases were treated with placebo for 1 month. Efficacy was assessed according to Prostate Massage Fluid (EPS) and National Institutes of Health (NIH) prostatitis symptom scores. Results The treatment group was cured in 1 case (2.8%), markedly effective in 7 cases (20.0%), effective in 16 cases (45.7%), the total effective rate was 22.8% and the total effective rate was 8.66%. In the control group, there were no cured cases, 2 cases (5 .7%) were markedly effective and 8 cases (22.8%) were effective. The total effective rate was 5.7% and the total effective rate was 8.66%. One in each group exited the trial within two weeks of treatment. There was a significant difference between the two groups in the total effective rate and total effective rate (P <0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P> 0.05). Conclusion Qianliean suppository in the treatment of chronic prostatitis is safe and effective, and the patient compliance is better
