Background: Alcohol abuse leads to alcoholic liver disease (ALD), for which no effective treatment is yet known. Gentiana Scabra Bge is a traditional Chinese medicine; its extract has a significant liver protection effect, but its effects on the mechanism of improving alcohol-induced toxicity remain unclear. Therefore, this study used cell and mouse models to investigate how Gentiana Scabra Bge extract (GSE) might affect the TLT4/NF-\kappaB inflammation pathway in ALD. Methods: In mice, we induced the alcoholic liver injury model by applying alcohol and induced the inflammatory cell model by lipopolysaccharide (LPS)-induced macrophages. Using an enzyme-linked immunosorbent assay (ELISA) kit, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and interleukin 1\beta (IL-1\beta), interleukin 6 (IL-6), and tumor necrosis factor-\alpha (TNF-\alpha) levels were measured in liver tissue; we also performed histological analysis of liver tissue sections to assess the hepatoprotective effect of GSE on alcohol. Using real-time fluorescence quantification, we determined the expression of toll-like receptor 4 (TLR4) and nuclear factor \kappaB (NF-\kappaB) mRNA levels; we used Western blotting to detect the expression of TLR4/NF-\kappaB signaling pathway-related proteins. Results: We demonstrate that GSE decreased AST and ALT activity, ameliorated liver dysfunction, decreased cytokine levels, and reduced LPS-induced cellular inflammation. In addition, GSE protected mouse liver cells from the inflammatory response by reducing alcohol-induced liver pathological damage and downregulating genes and proteins such as nuclear factors. Conclusions: GSE can attenuate liver injury in mice through the TLR4/NF-\kappaB pathway by inhibiting the activation of nuclear factors.
