Serenoa repens, commonly known as saw palmetto, is the sole species currently classified in the genus Serenoa. It is a small palm, growing to a maximum height around 7–10 ft (2.1–3.0 m). It is endemic to the subtropical Southeastern United States, most commonly along the south Atlantic and Gulf Coastal plains and sand hills. It grows in clumps or dense thickets in sandy coastal areas, and as undergrowth in pine woods or hardwood hammocks.
However, according to the American Cancer Society, “available scientific studies do not support claims that saw palmetto can prevent or treat prostate cancer in humans”.
A meta-analysis by the Cochrane Collaboration found that saw palmetto berry extract given therapeutically, even at double and triple doses, did not improve urinary flow or improve the prostate gland size in men with benign prostatic hyperplasia (BPH). Two large trials published between the newer and older meta-analysis found the extract to be no different from placebo. Although a 2016 review included trials with a special standardized extract of saw palmetto called Permixon. This suggests that the lack of an effect found in the most recent Cochrane review was due to the differences in the saw palmetto extracts used.
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.
Saw palmetto (Serenoa repens) is a type of palm native to the southeastern United States.
The berries of the plant are commonly used in supplements to improve prostate health, balance hormone levels, and prevent hair loss in men.
It’s also associated with other benefits, including decreased inflammation and improved urinary function.
Saw palmetto can reduce the symptoms of enlarged prostate, including frequent urination, painful urination, sudden urge to urinate, and inability to urinate. It can also decrease the need to urinate during the night, increase urine flow, and make it easier to empty the bladder completely. Saw palmetto seems to work about as well as some prescription medications, but it takes about one or two months of treatment before symptoms improve.
