Key Constituents
The principal anti-inflammatory compounds; AKBA inhibits 5-lipoxygenase. Absorption improves when taken with a high-fat meal.
Additional constituents of the oleo-gum-resin.
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.
Pharmacological Actions
Anti-inflammatory (inhibits 5-lipoxygenase / leukotriene synthesis and NF-kB signalling); Reduces inflammatory markers (e.g. hs-CRP) and, in one RCT, improved knee joint-space and reduced osteophytes on radiograph
Boswellic acids, especially acetyl-11-keto-beta-boswellic acid (AKBA) from Boswellia serrata, induce cell-cycle arrest and apoptosis and inhibit proliferation, invasion and metastasis across lung, colorectal and prostate cancers (preclinical, incl. in vivo).
Traditional & Indicated Uses
Osteoarthritis: reduces joint pain and stiffness and improves function (over at least 4 weeks); Supports inflammatory arthritis including rheumatoid arthritis
Boswellia serrata resin and its triterpenoid AKBA arrest the cell cycle and induce apoptosis in non-small-cell lung cancer, suppress colitis-associated colorectal cancer (NF-kB, gut microbiota) and inhibit prostate cancer (IL-17 pathway) in vitro and in vivo (preclinical).
Supportive in inflammatory bowel disease (ulcerative colitis, Crohn's disease)

Safety, Cautions & Contraindications
Generally well tolerated; the most commonly reported side effects are mild gastrointestinal symptoms, and allergic reactions are rare.
Boswellic acids can affect drug-metabolising enzymes, so caution is advised when taking other medicines; safety in pregnancy and breastfeeding is not established, so avoid medicinal doses.
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
Small to medium deciduous tree with thin, papery, peeling bark. The leaves are pinnately compound with numerous small, toothed leaflets, clustered toward the branch tips. Small, pale yellow to white flowers are borne in axillary racemes. When the bark is cut, it exudes a fragrant, resinous gum (oleo-gum-resin) that hardens into pale, waxy tears - the medicinal part.[12]
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
Native to dry, rocky, hilly terrain of India and parts of the Middle East and North Africa, where it is tapped for its resin much like frankincense (Boswellia sacra).[12]
Native to the Mediterranean region; widely cultivated as a culinary herb and ornamental tree in warm-temperate and Mediterranean climates worldwide.[11]
Harvesting
The bark is deliberately incised and the exuded oleo-gum-resin is allowed to harden and is collected over several days to weeks, then cleaned and graded before use or extraction.[12]
Leaves are picked year-round from established plants and used fresh or dried; berries/seed are collected once ripe in autumn.
Traditional Uses
Boswellia resin (salai guggul) is a mainstay of Ayurvedic medicine for inflammatory joint and respiratory conditions, and has been burned as incense across many cultures. Modern standardised extracts, rich in boswellic acids, are used for osteoarthritis, inflammatory bowel disease and other inflammatory conditions, directly building on this traditional anti-inflammatory reputation.[12]
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]
Preparations
Dosage
Clinical trials in osteoarthritis commonly use extracts providing around 100-250 mg of boswellic acids (or several hundred mg of standardised extract) daily, in divided doses, taken with food. Educational reference only, not a prescription.
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.
