The use of the Arjun tree (Terminalia arjuna) for cardiovascular health is supported by both traditional and scientific evidence, with a moderate level of scientific validation. In Ayurveda, Arjuna bark has been used for centuries to manage heart conditions, such as angina, hypertension, and heart failure. Modern research provides additional support, though most studies are small or preliminary.

Mechanistically, Arjuna bark contains bioactive compounds such as flavonoids, tannins, and glycosides that exhibit antioxidant, anti-inflammatory, and cardioprotective effects. Clinical studies suggest that Arjuna extract may improve cardiac function, reduce angina episodes, and lower blood pressure. For instance, a double-blind, placebo-controlled study published in the International Journal of Cardiology (1995) showed that standardized Arjuna bark extract improved symptoms and cardiac function in patients with stable angina. Other research has demonstrated potential benefits in reducing cholesterol and improving left ventricular function.

Despite these promising results, the majority of human trials are of limited size and duration, and there is a need for larger, well-designed clinical trials to confirm efficacy and safety. Nonetheless, the convergence of traditional use and emerging scientific data supports Arjuna’s role as an adjunct in cardiovascular care, with a moderate level of scientific validation.
