With the improvement of people's living standards and the change of eating habits,
non-alcoholic fatty liver disease (
NAFLD) has gradually become one of the most common chronic
liver diseases in the world. However, there are no effective drugs for the treatment of
NAFLD. Therefore, it is urgent to find safe, efficient, and economical anti-
NAFLD drugs. Compared with western medicines that possess fast
lipid-lowering effect, traditional Chinese medicines (TCM) have attracted increasing attention for the treatment of
NAFLD due to their unique advantages such as multi-targets and multi-channel mechanisms of action. TCM monomers have been proved to treat
NAFLD through regulating various pathways, including
inflammation,
lipid production,
insulin sensitivity,
mitochondrial dysfunction, autophagy, and intestinal microbiota. In particular,
peroxisome proliferator-activated receptor α (
PPAR-α),
sterol regulatory element-binding protein 1c (SREBP-1c), nuclear
transcription factor kappa (NF-κB),
phosphoinositide 3-kinase (PI3K), sirtuin1 (
SIRT1),
AMP-activated protein kinase (AMPK), p53 and nuclear factor erythroid 2-related factor 2 (Nrf2) are considered as important molecular targets for ameliorating
NAFLD by TCM monomers. Therefore, by searching PubMed, Web of Science and SciFinder databases, this paper updates and summarizes the experimental and clinical evidence of TCM monomers for the treatment of
NAFLD in the past six years (2015-2020), thus providing thoughts and prospects for further exploring the pathogenesis of
NAFLD and TCM monomer
therapies.
