Lycium barbarum is a kind of traditional Chinese medicine. Lycium barbarum tastes sweet and juicy with many benefits such as nourishing liver and kidney, improving eyesight, delaying aging, etc. Lycium barbarum polysaccharide (LBP) is the main active ingredient of Lycium barbarum which has been widely used in the treatment of cardiovascular diseases in China. It has many biological activities such as anti-oxidation, anti-aging, relieving body fatigue, regulating blood lipid and blood glucose. Recent studies on LBP have shown that LBP is involved in cardiac protection through various mechanisms such as blocking l-type calcium channel, antioxidant reaction, improving myocardial fibrosis, inhibiting apoptosis, and anti-cytotoxicity. In this paper, the relevant research contents are summarized in order to provide reference for clinical research.
