Tea polyphenols (TP) are important functional components in tea. TP can regulate the composition of human intestinal flora, meanwhile, TP can be bio-transformed by the intestinal microbiota, resulting in relative metabolites, which prevent nerve damage, promote neurocognition, and increase resistance to oxidative stress. In recent years, cerebral nerves have become a hot topic of research, and studies have marked the importance of microbial flora and TP in protecting cerebral nerves. This paper reviews the effects of TP on intestinal microflora and the microbial degradation of TP. Furthermore, the potential effects of TP on cerebral nerves have been highlighted. PRACTICAL APPLICATIONS: Neuroscience studies are primarily focused on discerning the functional mechanism of the nervous system. The functional role of intestinal microbiota in host physiology regulation, especially neurological functions, has become a hotspot for neurological research. TP play a vital role in maintaining the steady status of intestinal flora and protecting cerebral nerve damage. An in-depth understanding of the TP and intestinal microbiota interaction, its implication on cerebral nerve protection, and the associated underlying mechanism will allow us to expand the therapeutic applications of TP. © 2020 Wiley Periodicals LLC.
