Botanical Overview
Saw Palmetto (Serenoa repens) belongs to the Arecaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The palm family (Arecaceae) includes trees, shrubs, and climbers with unbranched stems topped by a crown of large, compound, evergreen leaves. The flowers are small and clustered on branched inflorescences, and the fruits are typically drupes. Palms provide oils, waxes, and other useful products.
