History

Research on the chemical components of Danshen was initiated in the 1930s. Much research on the lipophylic components have been carried out. More than 40 lipophylic compounds have been identified. The research on the hydrosoluble components of Danshen was conducted later. Since the discovery of tanshinol, Chinese scholars isolated a series of hydrosoluble compounds from Danshen. These compounds have the structure of phenolic acid. They are named as salvianolic acids in alphabetic order, salvianolic acids A, B, C, D, E, G, H, tetramethyl salvianolic acid F, isosalvianolic acid C, rosmarinic acid, lithospermic acid, etc. The lipophylic and hydrosoluble compounds have been developed into many preparations for clinical application.

Indications

Danshen preparations are mainly used in treating cardiovascular and cerebrovascular diseases, liver diseases, renal failure, cancer, and so on.

Pharmacology

The study proved that Danshen extracts and their components have many pharmacological actions. It was demonstrated that salvianolic acids have strong antioxidant actions. It has been shown by experiments that salvianolic acids can scavenge oxygen-free radicals and inhibit the peroxide reactions of lipids. Salvianolic acids also have significant inhibiting effects on the aggregation of platelets. Many experiments showed that Danshen can significantly protect the heart and brain against ischemia-reperfusion injury. Danshen also showed obvious protective effects on liver injuries and renal function impairment caused by multiple factors.

Clinical Use

Danshen preparations have been used to treat many diseases, such as cardiovascular disease, stroke, refractory hepatic diseases, pulmonary diseases, hypertension, infectious diseases, cancer, adhesive ileus, etc. Although Danshen has little toxicity, some adverse reactions have been reported. Danshen preparations may lead to adverse cardiovascular effects and should be used with caution.
