Present situation in preventing and treating liver fibrosis with TCM drugs.

Considerable evidences have shown that the mechanism of TCM drugs for preventing and treating liver fibrosis is very complicated. TCM treatment can not only inhibit viral replication, ameliorate inflammation and promote blood circulation in the liver, and enhance regeneration of the hepatic cells, but also inhibit HSC proliferation, intra- and extracellular secretion, decrease the secretion of collagen and promote its degradation and re-absorption. However, most of the animal models are only suitable for studies of acute hepatitis. Establishment of cell lines suitable for studies of fibrosis is still at its initial stage. What we expect is that comprehensive clinical studies in TCM treatment of liver fibrosis will be carried out and evaluation of each datum given, both of which are of importance.
