Water extract of green tea attenuates alcohol-related hepatitis by inhibiting liver inflammation and gut microbiota disturbance in mice

Green tea is one of the main types of tea in China, and it has been widely consumed in the world. This study aims to investigate the potential mechanism by which the water extract of green tea (GTWE) may be effective in the treatment of alcohol-related hepatitis (ARH), utilizing a combination of network pharmacology, molecular docking, and experimental validation. Through network pharmacology analysis, seven active components and 45 potential targets were identified, with TLR4 being confirmed as the central target. Experimental findings demonstrate that GTWE exhibits significant efficacy in mitigating alcohol-induced liver inflammation and steatosis. Furthermore, the administration of GTWE has demonstrated significant efficacy in mitigating alcohol-induced intestinal inflammation and microbiota disturbance while concurrently restoring intestinal barrier function. Consequently, GTWE exhibits considerable potential as a pharmacological intervention and warrants further research and development as a lead compound for the treatment of ARH. Moreover, the prospective utilization of green tea in prolonged intakes exhibits potential as a prophylactic nutritive regimen against ARH.
