What is Saw Palmetto?
Saw Palmetto has been widely used in Europe and Canada for years, and more recently in the United States. Saw Palmetto also known as Serenoa repens, Serenoa serrulata, and sabal. The fruits of the saw palmetto are highly enriched with fatty acids and phytosterols, and extracts of the fruits have been the subject of intensive research for the treatment of urinary tract infections. This extract is also commonly used for other medical issues. Saw Palmetto blankets forest floor in southern Highlands County, Florida, United States.
Saw palmetto is a fan palm (Arecaceae tribe Corypheae), with the leaves with a bare petiole terminating in a rounded fan of about 20 leaflets. The petiole is armed with fine, sharp teeth or spines that give the species its common name. The leaves are light green inland, and silvery-white in coastal regions. The leaves are 1-2 m in length, the leaflets 50-100 cm long. They are similar to the leaves of the palmettos of genus Sabal. The flowers are yellowish-white, about 5 mm across, produced in dense compound panicles up to 60 cm long. The fruit is a large reddish-black drupe and is an important food source for wildlife and historically for humans.
The plant part used is the berry, and the active constituents are free fatty acids and sterols that are standardised to 85-95%.
What does Saw Palmetto do?
There is much research and documentation that supports the benefits of Saw Palmetto for prostate and the urinary tract. Nearly 50% of men over 50 will experience benign prostatic hyperplasia (BPH), an enlargement of the prostate. Saw Palmetto may be as effective in treating BPH as prescription medication. A clinical trial conducted in France reported that the number of times men had to urinate at night decreased by 45%, and urine flow rate increased by 50%.
In another study, 1300 men that suffer from enlarged prostate were given Saw Palmetto extract for 12 weeks, the participants noted the following:
