boswellia improves inflammatory bowel disease
In plain terms: Does boswellia help IBD (ulcerative colitis or Crohn's)?
Part of: 🧪 boswellia
Not proven. Small early studies hinted at benefit in ulcerative colitis, but a well-run trial found it no better than placebo for Crohn's. Not established.

Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Human trials (RCT / n-of-1)
How the studies fall
What the evidence shows
Promising in theory, unproven in practice. Small early trials suggested benefit in ulcerative colitis, but a well-conducted RCT found boswellia no better than placebo for maintaining Crohn's remission, and systematic reviews call the controlled evidence limited. Not established for IBD.

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.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
