Inflammatory bowel diseases (IBD) are the common health concern in populations across the world. Clinical evidence suggests that IBD, characterized by intestinal inflammation, is associated with neuronal manifestations to a greater extent. In this study, we have investigated the protective effects of Viphyllin™, a standardized black pepper (Piper nigrum) seed extract containing 30% β‐caryophyllene against dextran sodium sulfate (DSS)‐induced colitis in mice. Oral pretreatment of Viphyllin at the 50 mg and 100 mg/kg doses significantly reversed the clinical symptoms of colitis in mice. Viphyllin markedly inhibited NLRP3 inflammasome activation and improved barrier function in colon tissue. Viphyllin further mitigated the DSS‐induced anxiety‐like behavior in mice. Interestingly, Viphyllin improved brain antioxidant status and promoted neuronal cell survival in colitis model mice. In conclusion, our findings strongly support the health claims of Viphyllin as a functional ingredient to deal with IBD and related neuronal symptoms. Practical applications Prevalence of inflammatory bowel diseases is not uncommon in the modern lifestyle. Gut health is associated with neurological disorders that contribute substantially to the deterioration of quality of life and socioeconomic development. In this research work, the protective action of a black pepper seed extract standardized to 30% β‐caryophyllene (Viphyllin) is evaluated against Dextran sodium sulfate‐induced experimental colitis model. Here we have demonstrated the beneficial role of Viphyllin in mitigating intestinal inflammation as a function of NLRP3 inflammasome inhibition. Further, the extract improves intestinal barrier function. In an important aspect of the study, we have provided the data on the effect of Viphyllin on neurological symptoms and brain health in colitis model mice. Viphyllin™, an extract from the black pepper seeds, standardized to contain not less than 30 % β‐caryophyllene ameliorates intestinal inflammation by inhibiting the inflammasome activation and oxidative stress in DSS induced colitis model mice. The extract could further exert anxiolytic effect and protect neuronal cells from apoptosis and oxidative stress in mice.
