Curcumin is the most active constituent of the ground rhizome of the plant Curcuma longa, which has been demonstrated to have anti-inflammatory, anti-oxidative and anti-proliferative [used or tending to inhibit cell growth] properties. It has been found that curcumin has a substantial influence on the gut microbiota. Curcumin increased bacterial richness in mice. Furthermore, it prevented the age-related decrease in alpha diversity, increased the relative abundance of the order Lactobacillales, and decreased that of the order Coriobacteriales. The maintenance of a more diverse colonic microbial ecology correlates with a beneficial effect of curcumin on tumorigenesis [the production or formation of a tumour or tumours]. (1)
