Curcumin, the active compound in turmeric (Curcuma longa), has been investigated for its potential role in supporting or treating Irritable Bowel Syndrome (IBS). The rationale for its use is based on its anti-inflammatory, antioxidant, and possible gut-modulating properties. Several small-scale clinical trials and pilot studies have explored the effect of curcumin supplementation on IBS symptoms. A 2018 systematic review and meta-analysis found that curcumin supplementation, especially when combined with other ingredients like fennel oil, may reduce abdominal pain and improve quality of life in IBS patients. However, the number of studies is limited, sample sizes are small, and study quality is often moderate.

Mechanistically, curcumin is thought to reduce low-grade inflammation that may contribute to IBS symptoms, modulate intestinal barrier function, and influence gut microbiota composition. Traditional use of turmeric as a digestive aid in Ayurvedic and Chinese medicine lends some historical context, but the use of isolated curcumin for IBS is a more recent and scientifically-driven development.

In summary, while there is some scientific evidence suggesting curcumin may benefit IBS symptoms, the overall quality and quantity of evidence is modest (rating: 2/5). More large-scale, high-quality randomized controlled trials are needed to establish efficacy and recommend routine use for IBS.
