Taking gentian and liver pills for scrotal dampness does not work and patients are advised not to do this treatment. It has been reported in the literature that prolonged use of gentian and liver pills leads to an increased incidence of kidney cancer, and it is recommended that this treatment option must be terminated. The most likely cause of scrotal dampness is testicular syringomyelia, prostatitis or varicocele. It is recommended that the cause of the disease must be found and the primary cause treated. If it is testicular syringomyelia, surgery is recommended. If it is a varicose spermatoid vein, the varicose degree is treated with medication, orally, or with surgery if it is severe. Prostatitis must be treated with medication that can relieve scrotal dampness, effective daily cleaning of the scrotum, and diligent change of underwear.
