As given in Table 2, the levels of ALT, AST, and liver and serum TG at three pathological stages of CG-NAFL, CG-NASH, and CG-fibrosis and CG-NAFL + GXZY, CG-NASH + GXZY, and CG-fibrosis + GXZY mice did not change significantly, suggesting that the Gexia Zhuyu decoction had almost no toxic effect on the body, while also eliminating the interference of drugs with the measured indicators. This evidence concerns the gene GPT and fibrosis.
