Key Constituents
Major antioxidant constituents of corn silk; maysin is the predominant flavonoid quantified in standardised extracts.
Contribute to antioxidant and anti-inflammatory activity.

inferred from demulcent action
Diuretic - increases urine output to support the urinary tract and mild fluid retention/swelling; in conscious rats the aqueous extract is diuretic and kaliuretic and modifies glomerular filtration and potassium excretion

Safety, Cautions & Contraindications
Generally well tolerated. Not recommended in cases of fluid retention due to impaired cardiac or renal function. Ensure adequate fluid intake when using as a diuretic. May cause allergic reactions in individuals sensitive to Asteraceae plants. Avoid use during pregnancy and breastfeeding due to limited safety data.
Duke (2002) provides clinical evidence (score 2) for goldenrod's anti-inflammatory activity, consistent with Commission E approval. It is also classified as an aquaretic (increases urine output without electrolyte loss) and antispasmodic, used for urinary tract irrigation therapy. Dose: 6–12 g dried herb daily as tea for urinary complaints. Duke cautions against use in cases of edema from renal or cardiac insufficiency, and notes that the herb may cause allergic reactions in individuals sensitive to Asteraceae plants (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
Perennial herb (Asteraceae), 20-100 cm tall, with erect, often reddish, downy or smooth stems. Leaves are alternate, lance-shaped and toothed. Numerous small, bright yellow, daisy-like flower heads are clustered into branched, plume-like terminal sprays, followed by small ribbed achenes with a tuft of hairs (pappus).[1]
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
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
The flowering aerial parts are cut during flowering (late summer) and dried.[11]
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
Goldenrod has a long European folk-medicine tradition as a mild 'aquaretic' diuretic and anti-inflammatory remedy for the urinary tract, used traditionally for urinary-tract irrigation therapy alongside adequate fluid intake, and topically as a wound herb (one common name is 'woundwort'). Modern phytochemical work confirms saponin- and flavonoid-driven anti-inflammatory, antioxidant and diuretic activity.[1, 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]
