Used primarily in herbal medicine to support prostate health, particularly in managing symptoms of benign prostatic hyperplasia (BPH). The active compounds in the extract help reduce urinary frequency, improve urine flow, alleviate difficulty urinating, and decrease the sensation of incomplete bladder emptying by inhibiting the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT), a hormone that stimulates prostate enlargement.

Additionally, it is used to help reduce hair loss, especially in men with hereditary pattern baldness, due to its effect on lowering DHT levels in hair follicles, which contributes to follicle shrinkage and hair thinning.

In some cases, Saw Palmetto extract is employed to support sexual performance and libido, though scientific evidence for these benefits is less conclusive than for prostate health.

Generally available as capsules or tablets in dietary supplements, it is typically used long-term for noticeable effects. Commonly included in natural remedies for urogenital conditions in adult males.
