Ferulic acid and its derivatives have been investigated for their potential therapeutic effects in colitis, primarily in preclinical studies. Ferulic acid is a naturally occurring phenolic compound found in plant cell walls, known for its antioxidant, anti-inflammatory, and cytoprotective properties. Several animal model studies, particularly those involving dextran sulfate sodium (DSS)-induced colitis in mice or rats, have shown that ferulic acid and some of its derivatives (such as feruloylated oligosaccharides) can reduce the severity of colitis. These beneficial effects are attributed to the compound’s ability to scavenge free radicals, suppress pro-inflammatory cytokines (e.g., TNF-α, IL-6), inhibit NF-κB signaling, and maintain the integrity of the intestinal barrier.

For example, studies published in peer-reviewed journals like Inflammation (2017) and Food & Function (2016) demonstrated that ferulic acid administration ameliorated colonic inflammation, reduced histological damage, and modulated oxidative stress markers in murine models. However, evidence from human clinical trials is lacking, and most of the current scientific validation comes from in vitro and animal research. As such, while there is a scientific rationale for the use of ferulic acid derivatives in colitis, the evidence is not yet robust or directly translatable to clinical practice. Larger, well-designed human studies are needed to establish efficacy and safety in patients with colitis.
