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
Including columbianetin, angelicin, imperatorin and xanthotoxin.
Rich in monoterpenes such as alpha-pinene and beta-phellandrene; gives the aromatic, carminative character.
Antioxidant and anti-inflammatory constituents.
Aromatic constituents that drive the diuretic action but are toxic in large amounts.
Photosensitising constituents; the basis for the mild phototoxicity caution.
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)
Carminative and aromatic bitter digestive (indigestion, bloating, flatulence)
Carminative and aromatic bitter digestive (indigestion, bloating, flatulence)
Anticonvulsant and cognition-supporting (preclinical)
Carminative digestive and stomach tonic (bloating, indigestion)
Diuretic - reduces fluid retention/swelling and supports urinary and kidney function (traditionally used for urinary stones); animal studies attribute the effect to inhibition of the renal Na+/K+ pump, raising urine flow
Traditional & Indicated Uses
inferred from gastroprotective action
Anxiolytic / sedative (anxiety, nervous tension)
inferred from bitter-tonic action
inferred from anti-inflammatory action
Carminative and aromatic bitter digestive (indigestion, bloating, flatulence)
Angelica archangelica fruit tincture is antiproliferative against PANC-1 pancreatic cancer cells; its furanocoumarins imperatorin and xanthotoxin drive this activity and inhibit larynx cancer and rhabdomyosarcoma cell growth (preclinical).
inferred from neuroprotective action
Diaphoretic / expectorant support during colds
Carminative and aromatic bitter digestive (indigestion, bloating, flatulence)
inferred from anti-inflammatory action
inferred from sedative action
Anxiolytic / sedative (anxiety, nervous tension)
inferred from expectorant action
inferred from anti-inflammatory action
Overactive bladder - a pilot RCT of an Angelica archangelica leaf extract reduced daytime voids and storage symptoms and improved quality of life, with near-significant benefit for nocturia
Breath freshener (chlorophyll-rich; traditional for bad breath)
Carminative digestive and stomach tonic (bloating, indigestion)
inferred from hepatoprotective action

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.
Culinary amounts are safe, but medicinal/seed doses and the essential oil (apiole, myristicin) can be toxic and stimulate the uterus - AVOID medicinal doses of parsley in pregnancy.

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]
Biennial herb (Apiaceae), usually grown as an annual, 20-60 cm tall, with a slender taproot. Leaves are bright green and finely divided, either flat or tightly curled ('crisped') depending on variety. In the second year, small yellow-green flowers are borne in compound umbels, followed by small, ridged fruit (the 'seed').[11]
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]
Native to the central Mediterranean (Sardinia and southern Italy), long cultivated worldwide as a culinary and medicinal herb in gardens and as a field crop.[11]
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]
Leaves are picked fresh throughout the growing season; the root (of root-parsley varieties) is lifted in autumn; the seed (fruit) is collected from second-year plants once ripe and dry - it is used mainly in medicinal/aromatic preparations rather than food, given its higher concentration of the toxic essential-oil constituents apiole and myristicin.[11]
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]
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.
Culinary amounts of leaf are food-safe; medicinal use should stick to modest infusion amounts (roughly 2-4 g dried leaf or root per cup, a few times daily). Avoid concentrated seed extract or essential oil, which are toxic and uterine-stimulant at higher doses, and avoid medicinal doses entirely in pregnancy. Educational reference only, not a prescription.
