Terminalia arjuna is a deciduous tree found throughout India growing to a height of 60-90 feet. The thick, white-to-pinkish-gray bark has been used in India's native Ayurvedic medicine for over three centuries, primarily as a cardiac tonic. Clinical evaluation of this botanical medicine indicates it can be of benefit in the treatment of coronary artery disease, heart failure, and possibly hypercholesterolemia. It has also been found to be antibacterial and antimutagenic. Terminalia's active constituents include tannins, triterpenoid saponins (arjunic acid, arjunolic acid, arjungenin, arjunglycosides), flavonoids (arjunone, arjunolone, luteolin), gallic acid, ellagic acid, oligomeric proanthocyanidins (OPCs), phytosterols, calcium, magnesium, zinc, and copper.
印度楝是一种落叶乔木，遍布印度各地，可长到60至90英尺高。其厚实的树皮颜色从白色到粉灰色，在印度本土阿育吠陀医学中已被使用了三个多世纪，主要用作心脏滋补剂。对这种植物药的临床评估表明，它对治疗冠状动脉疾病、心力衰竭以及可能的高胆固醇血症有益。还发现它具有抗菌和抗诱变作用。印度楝的活性成分包括单宁、三萜皂苷（阿朱那酸、阿朱诺酸、阿朱宁、阿朱糖苷）、黄酮类化合物（阿朱酮、阿朱诺酮、木犀草素）、没食子酸、鞣花酸、低聚原花青素（OPC）、植物甾醇、钙、镁、锌和铜。
