Foods That Have Saw Palmetto
Palmetto is the common name for plant members of the genus Sabal and genus Serenoa. They are palm trees whose components are used for a variety of applications including wood pilings. Another widely known use for palmetto is as an herbal remedy, whose ingredients are derived from the species Serenoa repens and Sabal serrulata. Both species, referred to as “saw palmetto,” have been consumed by humans for centuries.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
Saw palmetto grows as tree or shrub varieties, with all species bearing "saw-toothed" leaves that fan out. These plants grow in warmer regions, such as on the southeast coastline of the United States, ranging from South Carolina to Louisiana, including Florida. Saw palmetto is found in a wide array of habitats including coastal sand dunes, pinelands and moist forests. Saw palmetto produces flowers that yield berries. Initially, the berries are yellow; however, they turn black with blue undertones when they become ripe. It is the saw palmetto’s berries that are used for medicinal purposes 2.

Consumption and Active Ingredients
Some alternative medical treatments come in the form of vitamins, minerals, enzymes and other related substances than can be found naturally in foods. However, saw palmetto berries are called “herbs” for common usage, and are not found in other foods beyond being a “food” type in itself 2. While early cultures ate saw palmetto berries directly off the tree/shrub, today, they are primary eaten in the form of dried berries, processed teas and liquid extracts to add to beverages. Saw palmetto also comes in the form of capsules and tablets 4. The primary ingredients that facilitate saw palmetto’s medicinal effects are plant sterols, fatty acids and flavonoids.

As in ancient times, saw palmetto is still used today to treat a plethora of conditions such as:
- migraine headaches
- sore throat
However, according to the National Institutes of Health and Mayo Clinic, there is insufficient evidence to support many health claims attributed to saw palmetto. Conditions treated with saw palmetto that NIH, Mayo Clinic and the University of Maryland Medical Center have reported effective include benign prostate hyperplasia (BPH) and conditions related to BPH, such as urinary tract problems. Also, recent animal studies have shown a measure of success in treating prostate cancer.
