My case may be different since I eat healthily, don't smoke or drink alcoholic beverages and exercise frequently. While Shou Wu has been targeted as a hair tonic, but also known to somehow improve functioning of bladder and kidneys, my comment is more of a miracle. My prostate problems have cleared up within one week of taking Advanced Shou Wu. No more burning while urinating, no more nightly frequent trips to bathroom, and I sleep uninterrupted for at least seven hours. Thank you. I love Shou Wu.
