(Terminalia arjua)

Part Used: Stem bark


The tree grows throughout the greater part of the Indian subcontinent, Burma and Sri Lanka. It is particularly found in the sub-Himalayan tracts.


In the Rigveda, the word Arjuna is used (R.V.1/122/5) for the first time. Both Carakacharya and Sushrutacharya have mentioned this plant in their Samhitas, but have not indicated its use for heart diseases. It was Vagbhattacharya who for the first time mentioned the use of Arjuna in the treatment of heart diseases and the same was endorsed by Cakradattam and Bhavamisram. Ayurveda recommends different formulation of the bark powder of arjuna.

Mechanism of Action

The saponin glycosides might be responsible for the inotropic effects of Terminalia, while the flavonoids and OPCs (oligomeric proanthocyanidins) provide free radical antioxidant activity and vascular strengthening or strengthening the circulatory system

Medicinal Uses

Various preclinical and clinical studies have been done on arjuna to prove its medicinal benefits. It is useful in angina pectoris, mild hypertension, dyslipidemia, atherosclerosis, blood thinning, as a diuretic and protecting cardiovascular disease or other diseases of heart.

Pharmacological Actions
Lipid Lowering Effect – Studies suggest that arjuna reduces blood lipids. The inhibition of hepatic cholesterol biosynthesis, increased fecal bile acid excretion, and stimulation of receptor-mediated catabolism of LDL cholesterol are responsible for arjuna’s lipid lowering effects.

Cardioprotective Effect - The antioxidant effect of the bark of T. arjuna augments endogenous cardiac antioxidants, like superoxide dismutase (SOD), reduced glutathione (GSH) and catalase (CAT). This offers significant protection against oxidative stress from tissue dysfunction or death in the heart (ischemic-repurfusion injury) caused when the blood supply to an area of tissue is cut off. The antioxidant effect also provides protection against endothelium dysfunction which is the pathological condition (cause) for atherosclerosis.

Clinical Studies
