Brahea Serrulata Plant Information
Brahea Serrulata grows in the following 7 states:Georgia, Mississippi, South Carolina, Alabama, Florida, Louisiana, Texas
The generic name honors American botanist Sereno Watson.Saw palmetto is a fan palm, with the leaves that have 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 teeth or spines are easily capable of breaking the skin, and protection should be worn when working around a saw palmetto. The leaves are light green inland, and silvery-white in coastal regions. The leaves are 1-2m in length, the leaflets 50-100cm long. They are similar to the leaves of the palmettos of genus Sabal. The flowers are yellowish-white, about 5mm across, produced in dense compound panicles up to 60cm long. The fruit is a large reddish-black drupe and is an important food source for wildlife and historically for humans. The plant is used as a food plant by the larvae of some Lepidoptera species such as Batrachedra decoctor, which feeds exclusively on the plant. This plant is also edible to humans, but the greener it is the more bitter tasting it would be.Its trunk is sprawling, and it grows in clumps or dense thickets in sandy coastal lands or as undergrowth in pine woods or hardwood hammocks. Erect stems or trunks are rarely produced, but are found in some populations. It is a hardy plant; extremely slow-growing, and long-lived, with some plants, especially in Florida possibly being as old as 500-700years.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 7-10ft (2-3m). It is endemic to the lowlands and savanna scrubs of the subtropical Southeastern United States, most commonly along the south Atlantic and Gulf Coastal plains.
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 symptomatic treatment of benign prostatic hyperplasia (BPH).
Early meta-analyses of clinical trials S. repens extract in the treatment of BPH concluded that saw palmetto extract is safe and effective for mild-to-moderate BPH compared to placebo, finasteride, and tamsulosin.[needs update] Two larger trials found the extract to be no different from placebo. An updated meta-analysis including these trials found that saw palmetto extract "was not more effective than placebo for treatment of hyperplasia."[needs update]
S. repens extract has been promoted as useful for people with prostate cancer. 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".
Indigenous names reported by Austin include: tala (Choctaw); cani (Timucua); ta :la (Koasati); taalachoba ("big palm", Alabama); ta:la a kko ("big palm", Creek); talco :b ("big palm", Mikasuki); talimushi ("palmetto's uncle", Choctaw), and guana (Taino, possibly). Saw palmetto fibers have been found among materials from indigenous people as far north as Wisconsin and New York, strongly suggesting this material was widely traded prior to European contact. The leaves are used for thatching by several indigenous groups, so commonly so that a location in Alachua County, Florida, is named Kanapaha ("palm house"). The fruit may have been used to treat an unclear form of fish poisoning by the Seminoles and Bahamians.
