Key Constituents
Including columbianetin, angelicin, imperatorin and xanthotoxin.
Rich in monoterpenes such as alpha-pinene and beta-phellandrene; gives the aromatic, carminative character.
Thymol is the principal active constituent, responsible for most of the antimicrobial, antispasmodic and carminative activity.
Secondary aromatic constituents contributing to the antimicrobial profile.
Pharmacological Actions
Angelica archangelica fruit tincture and its furanocoumarins (imperatorin, xanthotoxin) show antiproliferative activity against pancreatic and larynx cancer and rhabdomyosarcoma cells (preclinical).
Anticonvulsant and cognition-supporting (preclinical)
Carminative and aromatic bitter digestive (indigestion, bloating, flatulence)

Safety, Cautions & Contraindications
Contains furanocoumarins, which can cause photosensitivity; avoid excessive sun or UV exposure while using the herb medicinally.
Medicinal doses should be avoided during pregnancy and breastfeeding.
Coumarin constituents may interact with anticoagulant medicines, and furanocoumarins with photosensitising drugs; when wild-harvesting, take great care to distinguish garden angelica from poisonous Apiaceae look-alikes such as hemlock.
Generally safe at culinary amounts used in Indian and Middle Eastern cooking. Ajwain essential oil is highly concentrated and should not be ingested in large quantities — thymol toxicity can cause nausea, vomiting, and central nervous system effects at high doses. May increase photosensitivity (phototoxic potential of essential oil). May mildly lower blood pressure and blood sugar — caution when combined with antihypertensive or antidiabetic medications. Contains thymol, which may enhance anticoagulant effects at very high doses. Not recommended in medicinal doses during pregnancy (has emmenagogue properties in traditional use) or breastfeeding. Avoid in large amounts with peptic ulcer as it may aggravate gastric acidity in some individuals (Bairwa et al., 2012).
According to Duke (2002), ajowan essential oil is fungitoxic at 500 ppm and possesses spasmogenic activity. The oil is rich in thymol, which may be responsible for many of the plant's biological activities including its antispasmodic, carminative, and antimicrobial effects. Recommended dosage in traditional medicine is 3–6 g of powdered seed, or 125 mg of standardized extract (Duke, 2002).
External Ids
Botanical Description
Tall, robust biennial or short-lived perennial herb with a stout, hollow, ridged stem, often tinged purple. The leaves are large, bright green, 2-3-pinnately divided into broad, coarsely toothed leaflets, borne on inflated, sheathing stalks. Large, rounded compound umbels of small greenish-white to yellow-green flowers are borne at the stem tips, followed by pale, ribbed, winged fruit. The whole plant is strongly and pleasantly aromatic (sweet, celery- or juniper-like) when crushed.[6]
Slender annual herb with finely divided, feathery leaves, resembling a smaller parsley. Small white flowers are borne in flat-topped umbels, giving way to small, ridged, aromatic, oval seeds (technically schizocarps) that are the primary part used.[12]
Habitat
Native to northern and eastern Europe and parts of Asia, growing in damp meadows, riverbanks, ditches and woodland margins on moist, rich soils; also widely cultivated as a culinary and medicinal herb.[6]
Cultivated as an annual crop, mainly in India, Iran, Pakistan, Afghanistan and Egypt; believed native to the eastern Mediterranean region.[13]
Harvesting
The root is dug in autumn of the first year (or spring of the second, before flowering), when its aromatic oil content is highest; the ripe fruit/seed is collected in late summer as the umbels dry; leaves for standardised extract are picked through the growing season. Careful identification against deadly Apiaceae look-alikes (poison hemlock, water hemlock, hemlock water-dropwort) is essential before wild-harvesting.[6]
Seeds are harvested when the umbels dry and turn brown, then threshed and dried further; leaves are gathered fresh through the growing season and the root is dug when needed.[12]
Traditional Uses
Angelica root has a long Northern European tradition as an aromatic bitter and carminative digestive remedy for indigestion, bloating and flatulence, as a diaphoretic and expectorant support during colds, and the seed/fruit as a calming, anxiolytic nervine. It has also been candied and used as a flavouring.[6]
Ajwain seed has a long South Asian and Middle Eastern culinary and Ayurvedic tradition as a warming digestive carminative for bloating and indigestion, an antispasmodic for menstrual cramps, an oral-health antiseptic, and a respiratory-supportive remedy, with its high thymol content underlying much of its antimicrobial and antispasmodic activity.[1, 12, 14]
Preparations
Dried root decocted or infused in hot water as a bitter digestive and carminative tea.
Crushed fruit/seed infused as a calming, carminative tea.
Concentrated leaf extract studied in a pilot clinical trial for overactive bladder symptoms.
Dosage
Health Canada's NNHPD monograph gives 0.3-12 g of dried root and rhizome per day for adults 18 years and older, with infusion and decoction among the accepted methods of preparation. Educational reference only, not a prescription.
Health Canada's NNHPD monograph accepts a tincture among the methods of preparation for angelica root and rhizome, within the same 0.3-12 g dried-equivalent daily range for adults 18 years and older; it does not state a tincture ratio or volume. Educational reference only, not a prescription.
Traditional sources suggest around 3-6 g of powdered seed daily, or 125 mg of a standardized extract. Educational reference only, not a prescription.
