title: Terminalia arjuna Wight & Arn.--a useful drug for cardiovascular disorders.
abstract: Ancient Indian physicians used the powdered tree bark of Terminalia arjuna Wight & Arn. for alleviating "hritshool" (angina) and other cardiovascular conditions. Its stem bark possesses glycosides, large quantities of flavonoids, tannins and minerals. Flavonoids have been detected to exert antioxidant, anti-inflammatory and lipid lowering effects while glycosides are cardiotonic, thus making Terminalia arjuna unique amongst currently used medicinal plants. In this review an attempt has been made to discuss various aspects of its ethnomedical, pharmacognostical, phytochemical, pharmacological and clinical relevance to cardiovascular conditions. Experimental studies have revealed its bark exerting significant inotropic and hypotensive effect, increasing coronary artery flow and protecting myocardium against ischemic damage. It has also been detected to have mild diuretic, antithrombotic, prostaglandin E(2) enhancing and hypolipidaemic activity. There is ample clinical evidence of its beneficial effect in coronary artery disease alone and along with statin. However, toxicological studies in experimental animals are lacking. Considering its anti-ischemic activity and its potential to correct dyslipidemia, reduce left ventricular mass and increase left ventricular ejection fraction, it is essential to examine the molecular mechanism of its action and its core constituents. Proposition to administer Terminalia arjuna along with statins deserves to be explored in depth for defining its place in the over all management and prevention of coronary artery disease.
