A systematic review of the efficacy and safety of turmeric in the treatment of digestive disorders
Open accessAbstract
Turmeric has been gaining popularity as a treatment option for digestive disorders, although a rigorous synthesis of efficacy has not been conducted. This study aimed to summarize the evidence for the efficacy and safety of turmeric in the treatment of digestive disorders, including inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS), dyspepsia, gastroesophageal reflux disease, and peptic ulcers. Literature searches were conducted in Medline, EMBASE, AMED, the Cochrane Central Register of Control Trials, and Dissertation Abstracts from inception to November 15, 2021. Dual independent screening of citations and full texts was conducted and studies meeting inclusion criteria were retained: randomized controlled trials (RCT) and comparative observational studies evaluating turmeric use in people of any age with one of the digestive disorders of interest. Extraction of relevant data and risk of bias assessments were performed by two reviewers independently. Meta‐analysis was not conducted due to high heterogeneity. From 1136 citations screened, 26 eligible studies were retained. Most studies were assessed to have a high risk of bias, and many had methodological limitations. Descriptive summaries suggest that turmeric is safe, with possible efficacy in patients with IBD or IBS, but its effects were inconsistent for other conditions. The efficacy of turmeric in digestive disorders remains unclear due to the high risk of bias and methodological limitations of the included studies. Future studies should be designed to include larger sample sizes, use rigorous statistical methods, employ core outcome sets, and adhere to reporting guidance for RCTs of herbal interventions to facilitate more meaningful comparisons and robust conclusions.
Overview
CoChat Summary
TL;DR
This systematic review of 26 studies found mixed efficacy for turmeric/curcumin in digestive disorders, with some favorable signals in IBD and IBS but no meta-analysis due to high heterogeneity. Turmeric appeared safe, with no significant safety differences versus placebo or active comparators.
Key findings
- The review included 26 studies (25 RCTs and 1 randomized crossover trial); 14/26 (54%) were assessed as high risk of bias and the remaining 12 as unclear. Meta-analysis was not performed due to high heterogeneity.
- IBD (9 studies, 533 patients): all studies reported beneficial responses, but significant findings were limited to curcumin extract ≥1000 mg/day or bio-enhanced curcumin <1000 mg/day; low-dose curcumin extract and curcumin enema were non-significant. In CD, curcumin 1500 mg/day did not significantly differ from placebo for endoscopic or clinical relapse at 6 months, but severe endoscopic recurrence was greater with curcumin (p = 0.034).
- IBS (5 studies, 551 patients): mixed-formula curcumin products were significantly better than placebo in two studies (e.g., IBS-SSS p < 0.001; IBS-QoL adjusted difference of differences = 9.19 [95% CI 3.13–15.25]), but a third found no significant IBS-SSS difference (MD = 24.10, p = 0.26). Curcumin extracts showed no significant differences versus placebo, fumitory, or between doses.
- Dyspepsia, ulcers, and H. pylori: dyspepsia (5 studies, 511 patients) showed curcumin extract beneficial versus placebo but not versus active comparators. For gastric ulcers, antacid produced more complete healing than 750 mg/day curcumin (94.1% vs 70.6%, p < 0.05); for duodenal ulcers, 6000 mg/day curcumin did not differ from placebo (25.4% vs 28.1%, p = 0.736). In H. pylori, 2100 mg/day curcumin had lower eradication than triple therapy (5.9% vs 78.9%, p < 0.001), while a mixed-formula curcumin product was similar to quadruple therapy (55.8% vs 62.2%, p > 0.05). No studies suggested significant safety differences, though two reported withdrawal due to adverse events in the turmeric group.
Methods
- Systematic review with an a priori protocol, reported per PRISMA 2020. Searches were conducted in Medline, EMBASE, AMED, the Cochrane Central Register of Control Trials, and Dissertation Abstracts from inception to November 15, 2021, plus manual bibliography searches.
- Eligible studies were RCTs and comparative observational studies in people of any age with IBD, IBS, dyspepsia, GERD, or peptic/gastric/duodenal ulcers; interventions were curcumin or derivatives at any dose, duration, or route; comparators were placebo, active comparator, or no treatment; animal studies were excluded. After screening 1173 references, 26 studies were included.
- Dual independent screening and data extraction were performed, with risk of bias assessed using Cochrane ROB-1. Meta-analysis was not conducted due to high heterogeneity; findings were synthesized descriptively by condition, with Chi-squared or Fisher’s exact tests in Stata where raw data allowed, and forest plots generated in Comprehensive Meta-Analysis using standardized mean differences.
Limitations
- The paper states that the evidence base was limited by high risk of bias (14/26 high, 12 unclear), clinical and methodological heterogeneity, small sample sizes, poor reporting, variation in turmeric preparations, and concurrent standard therapy in IBD/IBS that makes isolating turmeric’s effects difficult.
- The paper also states that not all studies reported between-group comparisons, several used per-protocol rather than intention-to-treat analyses, adverse-event reporting was inadequate, some statistical methods were inappropriate, and zero cells limited precision.
- Evident from the text: because meta-analysis was not performed, no pooled effect estimates are available, and outcome definitions varied widely with minimal overlap across studies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-14, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-14 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
