Investigation of the effects of white tea on liver fibrosis: An experimental animal model

Abstract

Abstract Liver fibrosis is a common, progressive disease that affects millions of patients worldwide. In this study, it was aimed at investigating the effect of white tea on liver fibrosis in an in‐vivo environment by creating an experimental liver fibrosis model on rats. In this study, an experimental liver fibrosis model was created with carbon tetrachloride (CCl4) in Sprague–Dawley rats to investigate the effect of white tea on liver fibrosis. Rats are treated with CCl4 (1 mL/kg) to constitute the liver fibrosis model. White tea was given ad libitum with drinking water. As a result of the study, liver tissue hydroxyproline levels were found to be significantly lower (p = .001) in the white tea group. Histopathologically, it was found that the liver tissue histopathological damage score (LHDS) and fibrosis scoring were significantly lower (p < .001) in the white tea group. However, although it was not statistically significant in the group given white tea, compared with the fibrosis group, it was found that the malondialdehyde (MDA) level in the liver tissues was lower, the glutathione (GSH) level was higher, and the serum alanine aminotransferase (ALT) levels were lower. The study explained the effect of white tea on liver fibrosis and suggested that white tea might be beneficial in reducing the progression of liver fibrosis.
