Mechanism of action of Guan-Xin-Er-Hao (GXII) and hydroxysafflor yellow A (HSYA) in ameliorating atherosclerosis in ApoE−/− mice involves antioxidant and anti-inflammatory effects. The figure illustrates the antioxidant and anti-inflammatory mechanisms of Guan-Xin-Er-Hao and Hydroxysafflor Yellow A. By balancing antioxidant enzymes and MDA production; they reduce Reactive Oxygen Species (ROS); thereby alleviating endothelial dysfunction and oxidative stress. ROS-induced inflammation increases VCAM-1 express
