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.
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).
Demulcent / expectorant for cough, bronchitis and catarrh (mucilage soothes; saponins loosen mucus) - a double-blind RCT found violet-flower syrup, added to standard treatment, sped cough suppression in children with asthma
Demulcent / expectorant for cough, bronchitis and catarrh (mucilage soothes; saponins loosen mucus) - a double-blind RCT found violet-flower syrup, added to standard treatment, sped cough suppression in children with asthma
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)
inferred from anti-inflammatory action
Analgesic (pain relief); Osteoarthritis: reduces joint pain and stiffness and improves function (over at least 4 weeks)
inferred from anti-inflammatory action

Mild sedative for sleeplessness and to ease headache (traditional)
inferred from anti-inflammatory action
Mild sedative for sleeplessness and to ease headache (traditional)
inferred from expectorant action
inferred from demulcent action
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 well tolerated as flower/leaf preparations. It contains salicylates, so use caution if you are salicylate-sensitive; the root in large doses is emetic and purgative.
Safety in pregnancy and breastfeeding is not established, so avoid medicinal doses.

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]
Low, spreading perennial herb with heart-shaped, softly toothed leaves arising from a short rootstock, spreading by runners (stolons). Fragrant, deep violet-purple (occasionally white) flowers with five petals, the lower petal spurred, are borne singly on slender stalks.[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]
Grows in woodland edges, hedgerows, shaded banks and gardens on moist, humus-rich soils; native to Europe, North Africa and Asia and widely naturalised and cultivated elsewhere.[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]
Flowers are picked as they open in early spring; leaves can be gathered through the growing season and dried.[11]
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]
Sweet violet flower and leaf have a long European folk history as a soothing demulcent and expectorant remedy for cough, bronchitis and catarrh, and as a mild sedative for sleeplessness and headache; the flower syrup in particular has a long tradition as a children's cough remedy.[11]
Preparations
Resin extract standardised to boswellic acid (often AKBA) content, taken as capsules or tablets, ideally with a fat-containing meal to aid absorption.
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.
A double-blind randomised placebo-controlled trial used 5 mL of Viola odorata syrup every 12 hours for 4 weeks as add-on therapy for insomnia. Traditional references suggest around 2-4 g of dried flower and leaf per cup, up to three times daily. Note the EU monograph on Violae herba cum flore covers Viola tricolor, a different species, and its posology does not transfer here. Educational reference only, not a prescription.
