Here we are referring to the red inner bark beneath the outer glistening bark of the Terminalia arjuna tree. This tree is found growing in riparian zones and dry riverbeds in West Bengal, South and Central India. It’s been used in the traditional medicine system of India, Ayurved, for thousands of years. Most of the historical information indicates use for supporting cardiovascular health.* It was traditionally prepared by boiling the bark in milk (decoction). In line with the Doctrine of Signatures, the deep red coloring, indicates a use for vascularized areas and lymphatic regulation*. The outer bark naturally sheds once a year and lends itself easily at this time to harvest without harm to the tree.


Research on this herb has been conducted based on traditional use for supporting cardiovascular health*. Several antioxidants including gallic acid, ellagic acid and oligomeric proanthocyanidins have been identified in Arjuna bark. One research study conducted in ninety six humans looked at several indicators of cardiovascular health as well as blood sugar metabolism and showed promise for more research to be conducted.*
