Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
The A-type proanthocyanidins are considered responsible for inhibiting bacterial adhesion to the urinary tract lining.
Give the fruit its characteristic tartness and are traditionally credited with a mild urinary-acidifying effect.
Major antioxidant constituents of corn silk; maysin is the predominant flavonoid quantified in standardised extracts.
Contribute to antioxidant and anti-inflammatory activity.

Safety, Cautions & Contraindications
Food amounts are generally considered safe (berries in meals, drinks, sauces). (Williams et al., 2023).
Duke (2002) includes cranberry primarily at the experimental level for its astringent, diuretic, and antioxidant properties. Commission E has not approved cranberry for specific indications, though there is evidence supporting its role in preventing urinary tract infections (UTIs) by inhibiting bacterial adhesion to uroepithelial cells (proanthocyanidins). Duke notes the high vitamin C and organic acid content. Food-grade consumption is considered safe and beneficial as a urinary acidifier (Duke, 2002).
As a diuretic it should be taken with plenty of fluids; use caution alongside prescription diuretics or medicines that affect potassium.
May lower blood sugar and blood pressure, so use caution with antidiabetic or antihypertensive medication; avoid concentrated medicinal doses in pregnancy - a high-dose standardised extract increased pre-implantation losses in pregnant rats (no fetal malformations were seen).

Botanical Description
Low, creeping, evergreen dwarf shrub (Ericaceae) with slender, wiry stems that root at the nodes. Leaves are tiny, alternate, leathery and ovate with in-rolled margins, dark green above and whitish beneath. Flowers are small, pink and four-petalled, sharply reflexed backward so that the protruding stamens and style resemble a crane's head and neck - the origin of the name 'craneberry', later shortened to 'cranberry'. The fruit is a small, round, tart red berry.[8]
Tall, robust annual grass with broad, strap-like leaves and a stout, jointed stem. Male flowers form a terminal tassel; female flowers develop on the ear (cob), each floret bearing a single long, silky style and stigma ('corn silk') that protrudes from the husk to catch pollen.[11]
Habitat
Native to boggy, acidic wetlands - sphagnum bogs and marshes - across northern and central Europe and northern Asia, requiring waterlogged, nutrient-poor, acidic peat soils.[8]
Cultivated worldwide as a major cereal food crop in warm-temperate to tropical climates on fertile, well-drained soils; not found wild, having been domesticated from a wild grass ancestor (teosinte) in Mesoamerica.[11]
Harvesting
Berries are hand-picked or wet-harvested (traditionally by hand-raking the bog) in autumn once fully ripe and deep red.[8]
The silky stigmas and styles are collected from the ears in mid- to late summer, just before or as pollination occurs, while still fresh and pale, then dried quickly to preserve colour and flavonoid content.[11]
Traditional Uses
Cranberry has a long northern-European and Native American tradition as a food and folk remedy for urinary complaints, valued for its tart, astringent, vitamin-C-rich fruit. Modern research on its proanthocyanidins supports a role in reducing bacterial adhesion in the urinary tract, consistent with the traditional use for cystitis and recurrent urinary tract infections.[2, 11]
Corn silk has a long traditional use across Chinese, Native American and European folk medicine as a gentle diuretic and soothing demulcent for urinary tract complaints, mild fluid retention and kidney support.[11]
Preparations
Dried corn silk infused in hot water as a traditional diuretic and urinary-support tea.
