The Basics

Saw palmetto is a fan palm that grows in warm climates. The plant produces berries that when ripe are dried for herbal preparations. The berries contain polysaccharides known for their anti-inflammatory and immune boosting properties.

Saw palmetto inhibits the production of dihydrotestosterone (DHT). This hormone contributes to enlargement of the prostate in men. Additionally, this mild herb stimulates the appetite, acts as a diuretic, and may enhance libido.

Sources

Saw palmetto is available in the following forms: dried berries, teas, encapsulated powder, tablets, tinctures, and extracts. Purchase standardized products (at least 85% fatty acids and sterols).

Guidelines and Cautions

Always follow package directions.

If a prostate problem is suspected, consult a medical professional. Do not self-dose saw palmetto to treat the prostate.

Women who are pregnant or nursing should not use saw palmetto.

Saw palmetto may affect hormone levels and should not be taken with contraceptive pills, patches, or hormone replacement therapy.

As with any vitamin, herb, or supplement - always consult a medical professional prior to incorporating these substances into your diet.

Peer Review by Leading Specialists

    Mark R. McLaughlin, MD

    While I have had some patients that describe improvement of their symptoms from various dietary supplements, there is little scientific evidence that they work. In small amounts, I do not believe they are harmful, but I am not convinced they are any more effective than adhering to a healthy, well-balanced diet. On the contrary, there is strong scientific evidence showing that patients with a poor overall nutritional status have higher complication rates from surgery.
