Indian frankincense

About the plant

Indian frankincense is a deciduous tree in the incense family, Burseraceae, native to the Indian subcontinent. It grows in dry tropical forests and rocky, hilly landscapes, where it tolerates seasonal drought.

The tree has pale, papery bark, compound leaves with toothed leaflets, and small cream-colored flowers. Cuts in the bark release an aromatic gum-resin that hardens into yellowish or amber tears; this resin, rather than the bark itself, is used medicinally.

The discovery

Known in Ayurveda as shallaki, Boswellia serrata has a long history of use for painful joints and inflammatory complaints. Its reputation developed through generations of traditional practice, not a single documented discovery. Modern researchers subsequently isolated boswellic acids from its resin and investigated their effects on inflammatory pathways, followed by small clinical trials of standardized extracts, particularly for knee osteoarthritis.

Traditional uses

• In Ayurvedic practice, resin preparations were used for painful or swollen joints.
• Traditional preparations were used for digestive complaints, including diarrhea and dysentery.
• The resin was used for respiratory complaints such as cough and wheezing.
• External preparations were used for skin complaints and wound care; these historical uses do not establish effectiveness.

Research details

How it's used

• For joint symptoms, oral capsules containing standardized Boswellia serrata resin extract are the best-studied preparation. Choose products with independent quality testing when available.
• Doses are formulation-specific: some enriched extracts have been studied at 100–250 mg daily, while conventional extracts have been studied at several hundred milligrams two or three times daily. These products are not interchangeable; confirm the product and dose with a pharmacist or clinician.
• If your clinician agrees, reassess pain and daily function after about 4–8 weeks. Stop if there is no meaningful benefit; the best duration of ongoing use is unknown.
• Use it alongside, not instead of, appropriate joint care. Resin tea, incense, and frankincense essential oil are not equivalent to studied oral extracts; do not swallow essential oil.

Safety

• Possible adverse effects include nausea, heartburn, abdominal discomfort, diarrhea, and allergic rash.
• Avoid medicinal use during pregnancy or breastfeeding because adequate safety data are lacking. Safety and appropriate dosing in children are not established.
• Long-term safety remains uncertain, and commercial extracts vary substantially in composition. Compound weights in the visual data indicate illustrative research emphasis, not measured resin percentages or proven contributions to benefit.
• A hot, red, suddenly swollen joint, especially with fever, needs prompt medical assessment rather than self-treatment.

Drug interactions

• Laboratory findings suggest possible effects on platelets. Check with a clinician before combining boswellia with anticoagulants or antiplatelet medicines such as warfarin, apixaban, or clopidogrel; the clinical bleeding risk is not well established.
• Laboratory studies suggest effects on some drug-metabolizing enzymes and transporters, but their importance in people is uncertain. Ask a pharmacist to review prescription medicines, particularly those requiring closely controlled blood levels.
