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.
Leaf essential oil dominated by 1,8-cineole and eugenol, giving the characteristic aroma and much of the antimicrobial and anti-inflammatory activity.
Contribute to the plant's anti-inflammatory and antioxidant activity.

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).
Generally safe when used in food amounts. Not toxic to people and safe to cook with. Leaves are very rigid and leathery - should be removed before eating as they don't soften with cooking and edges can be sharp. Insufficient reliable information about safety during pregnancy or breastfeeding - stick to food amounts. Large amounts of bay leaf tea may cause vomiting (emetic properties) and drowsiness (sedative properties). In high doses, bay laurel has cytotoxic activity. Some people may experience allergic contact dermatitis from bay laurel oil.
Duke (2002) notes antibacterial, anti-inflammatory, and antioxidant activities for bay laurel, primarily at the experimental level. The essential oil contains eugenol and 1,8-cineole as principal bioactive components. Traditional dosages in European phytotherapy include 1–3 g of dried leaf as a tea. Caution is advised as the essential oil may cause allergic contact dermatitis, and bay berries should not be confused with the less toxic leaves (Duke, 2002).

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 or small tree with dark green, glossy, aromatic leaves, smooth-edged and slightly wavy at the margin. Small, pale yellow-green flowers are borne in clusters in the leaf axils in spring, followed by small, dark purple-black berries on female trees.[11]
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 Mediterranean region; widely cultivated as a culinary herb and ornamental tree in warm-temperate and Mediterranean climates worldwide.[11]
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.
Leaves are picked year-round from established plants and used fresh or dried; berries/seed are collected once ripe in autumn.
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]
Bay leaf has an ancient Mediterranean culinary and medicinal history, used as a digestive carminative for indigestion and bloating, and topically and traditionally for muscle and joint pain and minor wounds; it remains one of the most widely used culinary herbs worldwide.[11]

Dosage
Not documented
Two clinical studies in healthy volunteers used an infusion prepared from 5 g of dried Laurus nobilis leaves in 100 mL of boiled water, taken once daily for 10 days. Traditional references suggest a smaller 1-3 g per cup up to three times daily; no EMA or WHO monograph exists for bay leaf. Educational reference only, not a prescription.
