ARJUNA ON HEART
Terminalia arjuna is an herb found in abundance in the Himalayan forests, Bengal, Bihar and Madhya Pradesh. The saponin glycosides found in this herb are responsible for an inotropic effect, meaning that the force with which the heart and other muscles contract is affected. The arteries are strengthened by its flavonoids and proanthocyanidins. This important herb also interacts with LDL cholesterol, accelerating its turnover in the liver and inhibiting its oxidation, thus contributing to cholesterol reduction in the body. Terminalia Arjuna has the potential to correct abnormalities in endothelial cells, those that line the interior of blood vessels. A study in 2003 indicates that it has beta-blocking activity. Terminalia has no toxicity, does not interact with drugs and has no contraindications.

Studies on this herb are very promising. In a 2002 double blind crossover study published in the Indian Heart Journal, 58 males diagnosed with ischemic heart disease were given either the standard medical treatment (isosorbide mononitrate, a blood vessel dilator), Terminalia Arjuna, or a placebo for one week. They were monitored for symptoms of angina (severe chest pain) during exercise. Terminalia reduced symptoms better than the placebo and was equal to the standard medical treatment.
