Wang et al.30obtained pomegranate peel extract (PoPx) from Punica granatumand and demonstrated that pretreatment in a Con A‐induced AIH murine model with PoPx obviously reduced the level of cytokines (TNF‐α, IFN‐γ and IL‐6), serum transaminases and the murine mortality rate, and played a protective role by decreasing the liver damage caused by ROS. Here, TNF is linked to autoimmune hepatitis.
