In plain terms: Does boswellia (frankincense) help arthritis and joint pain?

consensus score 0.79

Yes — it's one of the better-proven herbal joint remedies. Multiple trials find standardized boswellia extract eases knee-osteoarthritis pain and stiffness about as well as anti-inflammatory drugs, often with gentler effects on the stomach.

What the evidence shows

Boswellia's standout claim, and it's well-earned: multiple independent meta-analyses of RCTs find standardized Boswellia serrata extract (often the AKBA-enriched forms Aflapin/5-Loxin) reduces knee-osteoarthritis pain and improves function, with a favourable safety profile versus NSAIDs. One of the better-evidenced herbal joint remedies.

Cochrane agrees with us see how our grade compares ▾

Cochrane review 2014 · high-quality evidence (Boswellia arm: 2 studies, 85 participants) Agrees with our grade

Small total sample; the review's headline conclusion emphasises the ASU product. Boswellia-specific effect sizes need the full text.

“Oral herbal therapies for treating osteoarthritis (Cochrane CD002947.pub2, 2014). Meta-analysis was restricted to Boswellia serrata (monoherbal) and avocado-soyabean unsaponifiables. Five studies of three Boswellia serrata extracts were included; 'High-quality evidence from two studies (85 participants) indicated that 90 days treatment with 100 mg of enriched Boswellia' improved osteoarthritis outcomes.”

Why we agree: we reached the same direction independently, from our own appraisal of 11 sources. Two methods landing in the same place is a stronger signal than either alone.

What is Cochrane, and why trust it?

Cochrane produces systematic reviews: instead of running a new study, they gather every trial ever done on a question, judge how well each was run, and pool the results. They take no commercial or industry funding, which is why the medical community treats their reviews as a gold standard — and why we check our own verdicts against theirs.

Liu X, Machado GC, Eyles JP, Ravi V, Hunter DJ 2018 · Br J Sports Med	meta-analysis	supports	moderate	Systematic review with random-effects meta-analysis and meta-regression (NOT a network meta-analysis, as previously recorded here): 'An intervention systematic review with random effects meta-analysis and meta-regression', 69 eligible RCTs of 20 oral supplements vs placebo in hand, hip or knee OA. 'Boswellia serrata extract' is named among the seven supplements that 'demonstrated large (effect size >0.80) and clinically important effects for pain reduction at short term'; 'Similar results were found for physical function.' DENOMINATOR: the 69 studies span all 20 supplements - the abstract reports no per-supplement trial count, participant count or effect estimate, so the Boswellia subset's own denominator is cannot-tell from the available text. DURATION: short term only - 'No supplements were identified with clinically important effects on pain reduction at long term', and Boswellia is not among the two supplements ('green-lipped mussel extract and undenatured type II collagen') with clinically important medium-term pain effects. Quality moderate, not high: the authors' reliability statement lands on exactly this large-effect group - 'Some supplements with a limited number of studies and participants suggested large treatment effects' - and 'The Grading of Recommendations Assessment, Development and Evaluation suggested a wide range of quality evidence from very low to high'. Abstract-grade (Br J Sports Med is not in the PMC open-access subset).

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
