serenoa repens
 saw palmetto saw palmettoSharp spiky low-to-the-ground palm-tree shrub with white-green flowers and oval orange fruit clusters that turn black when ripe. Called “Saw” because of saw-like teeth along edge of leaf stems. Fruits taste terrible to some, but are famously used for prostate issues. Contains high levels of fatty acids, shown to reduce prostate enlargement symptoms, and beta-sitosterol, a potent blocker of DHT formation, thus helping hair grow, reduce prostate, improve urine flow, while reducing need to urinate at night.Serenoa repens
