Key Constituents
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.
Characteristic constituents; verbenalin has a dopaminergic effect.
Antioxidant and anti-inflammatory constituents.
Supporting antioxidant and aromatic constituents.

Safety, Cautions & Contraindications
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
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]
Slender, upright perennial herb with wiry, square, sparsely hairy stems and deeply lobed, toothed leaves. Tiny, pale lilac to pale purple, five-lobed flowers are borne sparsely along thin, wiry spikes at the ends of the branches, opening a few at a time.[11]
Habitat
Native to the Mediterranean region; widely cultivated as a culinary herb and ornamental tree in warm-temperate and Mediterranean climates worldwide.[11]
Grows on dry waste ground, roadsides, field margins and disturbed soil; native to Europe, North Africa and temperate Asia and widely naturalised elsewhere.[11]
Harvesting
Leaves are picked year-round from established plants and used fresh or dried; berries/seed are collected once ripe in autumn.
The flowering aerial parts are cut in summer as the plant comes into flower and dried in a warm, shaded, airy place.
Traditional Uses
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]
Vervain has an ancient European reputation, reflected in its old names 'holy herb' and 'herb of the cross', as a calming nervine for nervous tension, anxiety and sleeplessness, and as a bitter digestive tonic; it has also traditionally been used topically and internally for aches, pains and mild inflammation.[11]
Preparations
Dried leaf infused in hot water as a traditional digestive tea.
Not documented
Dosage
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.
