Pharmacological potential of ginseng and ginsenosides in nonalcoholic fatty liver disease and nonalcoholic steatohepatitis

Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease characterized by hepatic fat accumulation, while nonalcoholic steatohepatitis (NASH) is an advanced form of NAFLD characterized by hepatic inflammation, fibrosis, and liver injury, resulting in liver cirrhosis and hepatocellular carcinoma (HCC). Given the evidence that ginseng and its major bioactive components, ginsenosides, have potent anti-adipogenic, antiinflammatory, anti-oxidative, and anti-fibrogenic effects, the pharmacological effect of ginseng and ginsenosides on NAFLD and NASH is noteworthy. Furthermore, numerous studies have successfully demonstrated the protective effect of ginseng on these diseases, as well as the underlying mechanisms in animal disease models and cells, such as hepatocytes and macrophages. This review discusses recent studies that explore the pharmacological roles of ginseng and ginsenosides in NAFLD and NASH and highlights their potential as agents to prevent and treat NAFLD, NASH, and liver diseases caused by hepatic steatosis and inflammation.
