Whether you have prostatitis or interstital cystitis, you may need an anti-inflammatory herb for the urinary tract. In the case of non bacterial prostatitis and chronic pelvic pain syndrome, you need something to calm down the urinary system.
There are prescription urinary anti-inflammatory agents and urinary analgesics. I have better options which do not require a prescription. Some of these herbs are Corn Silk (Zea mays), Couch Grass (Elytrigia repens), Marshmallow Root (Althaea officinalis), and Cleavers (Galium aparine).
I use every one of these herbs. I have written blogs about each of these herbs over the years. I am fond of Corn Silk, but do not use it as often as I should. Corn Silk is a soothing aquaretic that has antibacterial properties and acts as a demulcent for the bladder, urethra, and prostate. The dose I use is 3-5 ml 2-3 times a day.
