Atherosclerosis (AS) is a chronic and progressive arterial disease. It is an important cause of the occurrence and development of cardiovascular and cerebrovascular diseases. With the development of Traditional Chinese Medicine (TCM), TCM has many advantages in the therapy of AS, with less adverse reactions. Studies have shown that TCM can resist AS, and the mechanism mainly belongs to regulating lipid metabolism, anti-lipid peroxidation, anti-inflammation, anticoagulation, and protecting the structure and function of vascular endothelial cells. The mechanism of TCM for AS is warranted to be studied systematically, and the chemical components need to be further clarified.
