Anti-fibrotic activity of natural products, herbal extracts and nutritional components for prevention of liver fibrosis: review

Abstract

Liver fibrosis is a grave problem worldwide, and the development of this condition is the first step towards cirrhosis. In fact, when lesions of different aetiologies chronically affect the liver, it triggers fibrogenesis, the resulting damage and the progression of fibrosis cause serious clinical influences including severe complications, expensive treatments, and death in end-stage liver disease. Although impressive progress has been reported in understanding the pathogenesis of liver fibrosis, no effective agent has been developed to prevent or reverse the fibrotic process directly. This article reviews natural products, herbal medicines and nutritional components that exhibited an anti-fibrotic activity through different mechanisms of action, including suppressing of cytokine production, inhibition of hepatic stellate cells “HSCs” propagation, modulation of the molecular mechanisms leading to hepatic fibrosis, free radical scavenging and anti-inflammatory properties.
