No documentation

Vernacular Name

White Marudah , arjuna, arjuna leaf, arjuna root.


Terminalia arjuna belongs to the Combretaceae family and is most popular for its cardioprotective properties. This ancient tree has come to be considered a sacred plant and both the leaves and flowers are given as offerings to Vishnu and Ganpati on some of the primary religious occasions in India.

This plant is commercially available is tablet and powder filled capsule form.

T. arjuna is a large evergreen tree of the family Combretaceae. Often growing as high as 30m, T. arjuna is supported by buttressed roots. The smooth bark of the tree is light grey on the exterior, peach or tan on the interior, and is susceptible to flaking off in large pieces. The leaves of T. arjuna are elliptical or lanceolate in shape, roughly 12-30cm in length and up to 10cm in width. The leaves sprout oppositely from short, often deep red stems, often no more than 6mm in length. In the summer months, T. arjuna produces numerous yellow or white flower clusters. The apical panicles are small and, when young are a light green, and mature into their color. In the coming months, T. arjuna yields numerous drupe fruits. The fruits are roughly 2.5-3.5cm in length.  Ovular in shape, the fruits are a deep shade of brown, and have five deep grooves long the length of the fruit.

Origin / Habitat

White Marudah is large deciduous tree growing to heights of around 18- 25m and found commonly in almost every part of India. This plant requires a good amount of moisture and grows well in areas close to streams and rivers.

T. arjuna has been investigated in regard to its potential role in cancer therapy.[3] The results of one study found that T. arjuna demonstrated antiproliferative activity in human breast adenocarcinoma, an action attributed to one of the active principles, casuarinin. In this study, casuarinin inhibited the proliferation of MCF-7 cells and induced apoptosis.[4] Casuarinin exhibits strong antioxidant properties.[5]

Additional research has indicated that T. arjuna demonstrates protective effects on DNA from andriamycin damage during chemotherapy.[6] The studies have also shown the potential of T. arjuna to treat gastric ulcer.[7]


T. arjuna possesses strong antioxidant properties, which have been reported in both pre-clinical and clinical studies.[8],[9],[10] Of particular interest to researchers are the various benefits found in regard to cardiovascular disease. Flavonoids of T. arjuna have been determined to provide antioxidant, anti-inflammatory and lipid lowering effects with glycosides, which are determined to be cardio tonic.[11] T. arjuna exhibits antifailure and anti-ischemic properties in men with chronic stable angina.[12]

One study compared the antioxidant properties of T. arjuna to those of vitamin E. In this study, T. arjuna was found to decrease lipid peroxidation, though not as significantly as vitamin E.[13] In another comparison study, the antioxidant properties of T. arjuna was compared to those of ascorbic acid. The arjunic acid demonstrated stronger and more potent antioxidant properties in several areas including hydrogen peroxide induced RBCs hemolysis and microsome lipid peroxidation.[14] A review study investigated published literature on the use of T. arjuna in hyperlipidemia. The study looked at positive outcomes of garlic and guggul as well as T. arjuna.  Garlic was found to exhibit positive results 50% of the time, guggul 80% and T. arjuna 100% of the time. Researchers stated that these positive results measurements indicated a need for further investigation by the medical community into the use of T. arjuna as adjunct therapy for hyperlipidemia.[15]

A powder of the bark of T. arjuna was studied in 40 patients to investigate the effect on ischemic mitral regurgitation after acute myocardial infarction. Twenty of the patients were given T. arjuna in addition to anti-ischemic treatment. Following up at one and three months, researchers reported a significant decrease in ischemic mitral regurgitation and reduction in angina frequency in patients taking the T. arjuna compared to those receiving only the conventional therapy.[16]

In a small human study of ten subjects already taking various cardiovascular medications, the addition of T. arjuna to their drug therapy resulted in significant improvement in left ventricular ejection fraction which was not noted in subjects not taking the T. arjuna. These results were noted without injury to kidney and/or liver.[1]

Interaction and Depletions

Interaction with other Herbs

No documentation

Interaction with Drugs

There are presently no reports of interactions with drugs or over the counter medications. However, herbal products should not be used in combination with other medications without guidance of a healthcare professional. 

Based on pharmacology, caution should be used when using cardiovascular drug therapies.

Precautions and Contraindications

Side effects

T. arjuna is contraindicated in obesity, as it tends to decrease the amount of fat eliminated from the body. For this reason, in an obese person, the risk/benefit ratio of the cardiovascular benefits must be evaluated.
