Salvianolic acid B is widely recognized for its potent antioxidant properties, making it valuable in the treatment of cardiovascular diseases. It helps protect against oxidative stress by scavenging free radicals and reducing lipid peroxidation, which can prevent damage to blood vessels and improve overall heart health. Additionally, it exhibits anti-inflammatory effects, making it useful in managing conditions like atherosclerosis and myocardial infarction. In traditional Chinese medicine, it is often used to promote blood circulation and alleviate symptoms of chronic diseases. Beyond cardiovascular health, Salvianolic acid B has shown potential in neuroprotection, where it may help mitigate neurodegenerative disorders by reducing neuronal damage caused by oxidative stress. It is also being explored for its anticancer properties, as it can inhibit tumor growth and induce apoptosis in certain cancer cells. Furthermore, its hepatoprotective effects make it a candidate for treating liver injuries and fibrosis. Research continues to uncover its therapeutic potential in various medical applications.
