Saw Palmetto is used as a dietary supplement for urinary symptoms associated with an enlarged prostate gland (also called benign prostatic hyperplasia or BPH), as well as for chronic pelvic pain, decreased sex drive, migraine, hair loss, and other conditions. The Saw Palmetto plant is scientifically known by the name Serenoa repens. The berries of this plant are dark brown in appearance and used for the treatment of particular types of baldness. This is exactly the reason why the extract of Saw Palmetto is used in some hair conditioners and shampoos. Saw Palmetto is also used for the treatment of enlarged prostate. As men get older, their prostate grows bigger in size and can push the urethral tube. Benign Prostatic Hyperplasia (BPH) is a common problem and is associated with issues like frequent urination, problems in urinating or maintaining urine. Saw Palmetto is also known to improve overall immunity and help the body to destroy harmful bacteria.
