Although there is little scientific evidence as of 2015, saw palmetto, beta-sitosterol, pygeum, rye grass pollen extract and stinging nettle are natural remedies to an enlarged prostate, as listed by Healthline. A diet low in grains and animal products is also recommended to reduce the risk of prostate problems.
Modern treatments for an enlarged prostate include surgical removal of extra prostate tissue, alpha-1 blockers to relax muscles in the prostate and antibiotics to combat chronic bacterial infections of the prostate. While the American Urological Association does not endorse herbal treatments for an enlarged prostate, early studies have promising evidence for some, as of 2015, reports Healthline.
Saw palmetto has been used in traditional medicine for centuries to treat urinary issues, but larger studies have found its effectiveness to be limited, according to Healthline. Beta-sitosterol is composed of cholesterol-like molecules gathered from plant sources, and has proven, positive effects on urine flow strength. Pygeum comes from the bark of the African plum tree and is another traditional medicine used for urinary problems. Early studies have found pygeum reduces the number of trips an individual takes to the bathroom on a daily basis. Rye grass pollen extract is thought to allow men to empty their bladder completely, reducing the need to urinate later. Nettle root is commonly used with other herbal supplements and is thought to generally reduce the symptoms of an enlarged prostate.
Diet can also affect prostate size, adds Healthline. Diets high in meat and grains can increase the risk of developing an enlarged prostate, while diets high in vegetables and polyunsaturated fats can prevent the development or treat an enlarged prostate.
