•• TONY ••:

I have modest belief in herbal remedies and even less it those that are applied by absorption through the skin from an impregnated plaster. I have tried plasters for other things, like weight loss, sciatica relief and arthritis treatment and none of them have worked for me.
I would recommend using medically prescribed drugs from your doctor, who will also attempt diagnosing the reason for your prostate inflammation, before you resort to a cure-it-all-whatever-the-cause remedy.
