Qian Lie Xian Yan Suppository ([symbol: see text]) was rectally applied to treat 104 patients with nonspecific chronic prostatitis (damp-heat syndrome with blood stasis) in contrast to 30 patients treated with traditional Chinese drug Ye Ju Hua Shuan ([symbol: see text] Suppository of Flos Chrysanthemi Indici). The results show that chronic prostatitis is markedly improved by using Qian Lie Xian Yan suppository, with a short-term cure rate of 23.1% and a total effective rate of 84.6%, superior to that of the control group. The animal experiment indicates that Qian Lie Xian Yan suppository has better anti-inflammatory and analgesic effects, with an action of promoting blood circulation.
