Key Constituents
Seed essential oil dominated by linalool, giving the characteristic aroma and much of the antimicrobial and carminative activity.
Antioxidant flavonoids and phenolics, notably quercetin derivatives, identified across leaf and seed extracts.

Safety, Cautions & Contraindications
• Food use is generally safe for most people (leaf in salads, seed as spice) (Burdock & Carabin, 2009). • Allergy is the main “big warning.” Coriander can trigger reactions ranging from mild oral itching to more serious allergy in sensitive people, especially those with pollen allergies (e.g., birch/mugwort) or other Apiaceae spice allergies (Thermo Fisher/Phadia, n.d.; Berghea et al., 2025). • If you use supplements (capsules/powder) and you take diabetes medication, be cautious: coriander seed powder has shown blood-sugar improvements in a small human trial, so it may add to the effect of glucose-lowering meds (Zamany et al., 2025). • Essential oil is not the same as the spice. Coriander essential oil is highly concentrated and should not be taken internally in “DIY doses.” It can be irritating, and safety data are discussed mainly for food-flavouring levels—not self-prescribed medicinal dosing (Burdock & Carabin, 2009). • Pregnancy / breastfeeding: normal culinary amounts are generally considered fine; “medicinal-dose” supplements or essential oil are best avoided unless guided by a qualified professional because safety data at higher doses is limited (Burdock & Carabin, 2009).
Duke (2002) provides clinical evidence (score 2) for coriander's role as an aperitif (appetite stimulant) and digestive tonic, consistent with Commission E approval. It demonstrates antispasmodic, carminative, and antifungal activities at the experimental level. Dose: 1–3 g crushed fruits (seeds) three times daily, or equivalent preparations. Duke notes mild hypoglycemic activity and a potential antiimplantation effect in high doses — use with caution in women attempting pregnancy (Duke, 2002).
Avoid internal use in pregnancy and breastfeeding: like goldenseal, the berberine it contains can cross the placenta and into milk and worsen newborn jaundice (kernicterus risk).

Botanical Description
Slender annual herb with delicate, broad, lobed lower leaves and finely divided, feathery upper leaves - a marked contrast within the same plant. Small white or pale pink flowers are borne in flat compound umbels, followed by round, ridged, aromatic seeds. The fresh leaf ('cilantro') has a distinctive citrusy aroma, often described as soapy by those with a genetic sensitivity to it.[4]
Evergreen shrub, 0.5-2 m tall, spreading by underground rhizomes to form thickets. The pinnate leaves resemble holly, with 5-9 glossy, dark green, spiny-toothed leaflets that often turn bronze-red in winter. Small, bright yellow, six-petalled flowers are borne in dense, upright terminal racemes in early spring, followed by clusters of blue-black, grape-like berries with a waxy bloom. The wood and inner bark of the stem and root are bright yellow when cut, owing to their high content of berberine-type alkaloids.
Habitat
Believed native to the Mediterranean region and Western Asia; cultivated worldwide as a culinary herb and spice crop on well-drained, sunny sites.[4]
Native to the Pacific Northwest of North America, growing in coniferous woodland understorey, forest margins and rocky slopes; widely introduced and naturalised as an ornamental and hedging shrub in temperate regions elsewhere.
Harvesting
Leaves are picked fresh through the growing season, before the plant bolts (flowers), when the flavour is best; the seed is harvested in late summer once the umbels have browned and dried, then threshed; the root can be dug at the same time as young leaves.
The root and root bark, the medicinal parts, are dug from established plants - traditionally in autumn - and dried. Because wild populations are slow-growing, cultivated or nursery-sourced material is preferred over wild-harvesting.
Traditional Uses
Coriander seed and leaf have a very long culinary and medicinal history across the Mediterranean, Middle East and Asia as a digestive carminative for indigestion, bloating and cramping, and, more recently, studied for calming/anxiolytic effects on the central nervous system alongside cardiovascular and metabolic benefits.[1, 4]
Oregon grape root has a traditional Native American and Eclectic-medicine history as a bitter tonic and alterative (blood-purifying) remedy and for skin conditions. Its main modern use, supported by clinical trials, is topical application of a standardised bark extract for mild-to-moderate psoriasis and atopic dermatitis (eczema), where its berberine-type alkaloids give anti-inflammatory and antiproliferative effects on skin cells.[1, 11, 12]
Preparations
Seed powder or extract studied for glycaemic and psychiatric-symptom support in clinical and preclinical work.
