Liver fibrosis is a gradual process of increased secretion and decreased degradation of extracellular materials (ECM). Most author hold that the process is initiated by the damage of hepatic cells (HCs), which leads to activation and secretion of multiple cellular factors of Kupffer cells. These factors, along with the cellular factors secreted by damaged HCs, thrombocytes and endothelial cells of the hepatic sinusoid, and some chemical mediators are activators of hepatic stellate cells (HSCs). Being activated, HSCs differentiate into myofibroblasts, and, via self-secretion and parasecretion, proliferate and synthesize a massive amount of extracellular materials which gradually accumulate and lead to formation of liver fibrosis.1 Since fibrosis is a common course in a variety of chronic liver diseases, prevention against its formation is of great importance. The following are the recent achievements of traditional Chinese medicine (TCM) in this field.
