Hepatoprotective effects of Di Wu Yang Gan: A medicinal food against CCl4-induced hepatotoxicity in vivo and in vitro.

Abstract The development of functional foods based on medicinal food ingredients has become a hot topic in China. Di Wu Yang Gan (DWYG) is a Chinese medicinal food that contains five dietary plants. Various health benefits, including anti-inflammation, liver regeneration regulation, have been reported, though the mechanism is not clear. This study aimed to investigate the protective effect of DWYG on carbon tetrachloride-induced acute liver injury (ALI) in embryonic liver L-02 cells and mice model. DWYG-medicated serum protected L-02 cells from carbon tetrachloride-induced damage, reduced the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the culture medium, decreased the expression of Bax and increased the expression of Bcl-2. Mice study suggested that DWYG decreased the levels of malondialdehyde, ALT and AST. Together, these results suggest the hepatoprotective effects of DWYG against ALI and provide an experimental basis for the utilization of DWYG to treat liver damage.
