consensus score 0.76

Generally yes — it's well-tolerated in trials, usually gentler on the stomach than anti-inflammatory drugs, with mild digestive upset the main complaint. Long-term data are thinner.

What the evidence shows

Generally well-tolerated. Across OA trials boswellia has a favourable safety profile — often better GI tolerability than NSAIDs — with mild digestive upset the most common complaint. Good short-to-medium-term safety; very-long-term data are thinner.

RCT supports low RCT: standardized boswellia was safe and well-tolerated over the trial period.
Dejonckheere CS et al
2025 · study_type: observational
observational supports low Meta-narrative review of 6 records (130 patients) on Boswellia serrata for radiation-induced cerebral edema/necrosis; reports 'Tolerability of BA was favorable, with mild gastrointestinal discomfort being reported most frequently.'

2011 · Clin Pharmacokinet
observational supports low Narrative review, no new data: 'Compared to NSAIDs, it is expected that the administration of BSE is associated with better tolerability, which needs to be confirmed in further clinical trials.' Tolerability is stated as an expectation awaiting confirmation, not as a measured safety outcome; zero-weighted per CONVENTIONS §5.

meta-analysis supports moderate Systematic review: boswellia showed good tolerability; adverse events mild and mostly gastrointestinal.

observational supports low Narrative (non-systematic) review of lifestyle interventions for arthritis pain, PubMed/EMBASE/Cochrane/Google Scholar 2000-2025, with no pooling and no data of its own: 'A search of PubMed, EMBASE, Cochrane Library, and Google Scholar (2000 to 2025) identified randomized trials, meta-analyses, and cohort studies on nutrition, supplementation, physical activity, and sleep.' On tolerability it states: 'Supplements like curcumin, glucosamine, and Boswellia showed modest benefits with favorable safety,' and concludes 'Lifestyle medicine is safe, effective, and feasible to integrate into arthritis care.' ON-TOPIC for this claim but SECONDHAND and unquantified - no adverse-event rates, no withdrawal counts, no dose or duration, no comparator, and Boswellia is bundled with curcumin and glucosamine in the same sentence. It restates trials already appraised in the boswellia hub rather than adding independent observation, which is why it stays evidence_role: review at zero weight.

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.
