Botanical Overview
Pumpkin (Cucurbita pepo) is a flowering plant in the Cucurbitaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The gourd family (Cucurbitaceae) includes climbing or trailing vines with tendrils, large alternate leaves, and showy yellow or white flowers that are typically unisexual. The fruits are fleshy gourds, melons, or squashes with many seeds. Many species produce cucurbitacins, bitter compounds with purgative and anti-inflammatory activity.

Urinary tract health.
- Diuretic
Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.
