Key Constituents
Seed oil dominated by the sesquiterpene alcohol carotol (often >75%), with alpha-pinene, sabinene, beta-caryophyllene, geranyl acetate and daucol; gives the aromatic, carminative and antimicrobial character.
Beta-carotene and other carotenoids, especially abundant in the root; carrot is the main dietary source of provitamin A.
C17-polyacetylenes (falcarinol, falcarindiol) with anticancer, anti-inflammatory, antifungal and antibacterial activity.
Antioxidant flavonoids such as luteolin, apigenin, quercetin and kaempferol, and phenolic acids such as chlorogenic and caffeic acid.
Major antioxidant constituents of corn silk; maysin is the predominant flavonoid quantified in standardised extracts.
Contribute to antioxidant and anti-inflammatory activity.
Pharmacological Actions
Classic diuretic and antilithic (stone-clearing) use; supported by antiurolithic activity in animal models.
Root extract protective and curative in renal ischemia-reperfusion injury and against cisplatin nephrotoxicity (preclinical).
Antisecretory, antacid and antiulcer activity; enhances the antiulcer effect of pantoprazole (preclinical).
Seed essential oil inhibits food-borne Gram-positive and Gram-negative bacteria.
Falcarinol-type polyacetylenes.
Falcarinol-type polyacetylenes and other constituents show anti-proliferative and anti-metastatic activity in vitro and in vivo (preclinical).
Carrot insoluble dietary fibre improved glucose tolerance in animal models (preclinical).
Insoluble dietary fibre reduced the post-load rise in blood lipids (preclinical).
Carrot seed oil bioactives promote wound healing (preclinical).
Aromatic bitter carminative for flatulent digestion (traditional).

Safety, Cautions & Contraindications
Wild carrot SEED has estrogenic and anti-implantation (pregnancy-interceptory) activity and a long reputation as an emmenagogue and folk contraceptive; medicinal doses of the seed should be avoided in pregnancy and when trying to conceive.
Like other Apiaceae, wild carrot contains furanocoumarins that can cause photosensitivity; skin contact with the sap plus sun exposure may cause phytophotodermatitis. Avoid excessive sun or UV exposure when using the herb medicinally.
Excessive intake of carrot or carotene can cause a harmless, reversible yellow-orange discolouration of the skin (carotenodermia).
CRITICAL foraging hazard: wild carrot grows among, and closely resembles, several deadly poisonous Apiaceae - poison hemlock (Conium maculatum), fool's parsley (Aethusa cynapium), hemlock water-dropwort (Oenanthe crocata) and water hemlock (Cicuta virosa). Never gather wild carrot for use unless every look-alike has been positively excluded. Wild carrot has solid, ridged, bristly-HAIRY stems, a carrot smell, three-forked bracts beneath the umbel and usually a single dark central floret; the deadly hemlocks have smooth, hairless stems (often purple-blotched) and an unpleasant smell.
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
Erect biennial herb of the carrot family, 30-100 cm tall, growing from a slender, whitish, aromatic taproot. The leaves are 2-3-pinnate, finely divided and feathery, and smell distinctly of carrot when crushed. Tiny white flowers are borne in a flat or slightly domed compound umbel, classically with a single dark purple-red floret at the very centre; a ruff of long, three-forked (feathery) bracts sits beneath the umbel. As the seed ripens the umbel curls inward into a concave 'bird's nest'. The stems are solid, ridged and roughly hairy (bristly).[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
Dry grassland, meadows, roadsides, field margins and waste ground on well-drained, often chalky (calcareous) soils. Native to Europe, south-west Asia and North Africa and widely naturalised across temperate North America, Australia and elsewhere. The cultivated carrot (Daucus carota subsp. sativus) was domesticated from this wild stock.[1]
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 ripe fruits (seeds) are collected from the drying umbels in late summer to autumn; the aromatic seed is the part richest in essential oil. The taproot is dug in the first-year rosette stage, before the plant flowers, when it is still tender; aerial parts are gathered while in flower. Only ever harvest where the plant can be identified with certainty against its deadly Apiaceae look-alikes.[1, 14]
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
Wild carrot has a long folk-medicinal history as a diuretic and urinary remedy for gravel, stones, cystitis and gout, and as a carminative aromatic bitter for flatulent indigestion. The seed is the classic part used and carries a well-documented traditional reputation as an emmenagogue and folk contraceptive ('Queen Anne's Lace seed'); experimental work confirms estrogenic and anti-implantation (pregnancy-interceptory) activity, which is also why the seed is avoided in pregnancy. The root is nutritive and rich in carotene, and the plant has been applied to wounds and inflamed skin.[1, 17]
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 seed or aerial parts (herb) infused in hot water as a diuretic and carminative tea - the traditional way of taking wild carrot for urinary and digestive complaints.
The bruised aromatic seed steeped or briefly simmered; the seed is the part richest in essential oil and is the classic diuretic and emmenagogue preparation.
Crushed leaf or grated root applied externally to wounds and inflamed skin, reflecting the traditional vulnerary use; carrot seed oil bioactives promote wound healing in animal studies.
Dried corn silk infused in hot water as a traditional diuretic and urinary-support tea.
