Here are studies on herbs that help with urinary tract issues and a man's reproductive system: Saw Palmetto Berry: https://www.ncbi.nlm.nih.gov/pubmed/23432584    Serenoa Repens, lycopene and selenium: a triple therapeutic approach to manage benign prostatic hyperplasia. https://www.ncbi.nlm.nih.gov/pubmed/25154739  Serenoa repens, lycopene and selenium versus tamsulosin for the treatment of LUTS/BPH. An Italian multicenter double-blinded randomized study between single or combination therapy (PROCOMB trial). https://www.ncbi.nlm.nih.gov/pubmed/12137626   Serenoa repens for benign prostatic hyperplasia.   REVIEWER'S CONCLUSIONS:  The evidence suggests that Serenoa repens provides mild to moderate improvement in urinary symptoms and flow measures. Serenoa repens produced similar improvement in urinary symptoms and flow compared to finasteride and is associated with fewer adverse treatment events. The long term effectiveness, safety and ability to prevent BPH complications are not known. The results of this update are in agreement with our initial review. NOTE: This is 3 of at least 64 studies on the NCBI PubMed site. Mullein: https://www.ncbi.nlm.nih.gov/pubmed/27980574  UHPLC-ESI-MS/MS and GC-MS Analyses on Phenolic, Fatty Acid and Essential Oil of Verbascum pinetorum with Antioxidant, Anticholinesterase, Antimicrobial and DNA Damage Protection Effects. https://www.ncbi.nlm.nih.gov/pubmed/25048704  Verbascoside--a review of its occurrence, (bio)synthesis and pharmacological significance. NOTE: This is 2 of at least 11 studies of Mullein. Parsley: https://www.ncbi.nlm.nih.gov/pubmed/24660617  Parsley: a review of ethnopharmacology, phytochemistry and biological activities. NOTE: This is 1 of at least 17 studies of Parsley. Decide for yourself if herbs can help a man's health.
