# Pumpkin Seed or Saw Palmetto?

Pumpkin seed (Cucurbita pepo) is eaten as a food, while saw palmetto (Serenoa repens) is sold as an extract; both are used for urinary symptoms of benign prostate enlargement. The table is built from the sourced cards of both herbs.

## Which one, when?

### Pumpkin Seed

### Saw Palmetto

A review of 27 studies found little or no benefit on its own for prostate symptoms; the EMA assesses only one specific hexane extract under well-established use. Raised INR has been reported with warfarin.
