curcumin improves ulcerative colitis remission

In plain terms: Does turmeric help ulcerative colitis?

consensus score 0.82

Yes, as an add-on. Layered on top of standard therapy, curcumin improves remission rates in ulcerative colitis across several trials — one of its better-evidenced uses. It's an adjunct, not a replacement for your medication.

What the evidence shows

One of curcumin's better gut claims: added on top of standard 5-ASA therapy, curcumin improves clinical response and remission in ulcerative colitis across several RCT meta-analyses. It's an adjunct to conventional treatment, not a standalone — and one prominent recent trial used a curcumin-indigo combination, so not all the benefit is curcumin alone.

Cochrane agrees with us see how our grade compares ▾
Cochrane review 2012 · low Agrees with our grade
“Curcumin may be a safe and effective therapy for maintenance of remission in quiescent UC when given as adjunctive therapy along with mesalamine or sulfasalazine. However, further research in the form of a large scale methodologically rigorous randomized controlled trial is needed to confirm any possible benefit of curcumin in quiescent UC.”

Why we agree: we reached the same direction independently, from our own appraisal of 10 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.

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.
