He visited Urologist, and chronic prostatitis was diagnosed. He visited our Chinese Medicine department on 2016/12/14. After four examinations were performed, we determined the patterns is dampness-heat in lower jiao. Based on Chinese medical differential diagnosis, we prescribed Chu Ling Tang. The symptoms improved after one week TCM treatment. After two months, there were no lower abdominal fullness, no hemospermia, and no dark brown within prostate fluid. In conclusion, Chinese Medicine may be the complementary therapy of chronic prostatitis and even can be the first choice of this intractable disease.
