Arjuna is an evergreen tree belonging to the genus Terminalia along with medicinal marvels like harad (Terminalia chebula) and baheda (Terminalia bellerica). The medicinal beauty of this ornamental tree lies in its inner bark which is considered a tonic for the heart. In fact, mentions of this tree are found in the Rig Veda. Ayurvedic doctors highly suggest arjuna bark for boosting the overall heart health. Medically speaking, the bark of Arjuna tree is vastly studied for its healing benefits on various heart diseases including strokes, heart attacks, and heart failure.

Originally a native of India, Arjuna tree is most commonly found near rivers and streams and it can grow up to a height of 25 to 30 metres. Arjuna bark is smooth and grey, but it has some green and red patches in between. The leaves of Arjuna are oblong (almost rectangular) and grow opposite to each other on its branches. The whitish cream flowers of this tree grow in clusters in the month of May to July. Arjuna fruit is greenish when fresh and turns a woody brown on maturity. The fruit has distinct wings which are one of the identifying features of Arjuna.

Arjuna herb for heart
Ayurvedic doctors suggest Arjuna tree bark powder for the treatment of cardiovascular conditions such as myocardial infections, coronary heart disease and ischemic attacks. It is known to be helpful in not only reducing risk but a regular consumption may help improve overall heart health and function.
Numerous animal-based and clinical studies have been done to test the efficiency of Arjuna tree bark in dealing with heart failure and heart-related illnesses. Studies suggest that the bark of Arjuna tree consist of a number of active biological compounds including flavonoids, tannins, and minerals which together make this tree the best cardioprotective you can ever get.
In a clinical study, 10 heart patients were given Arjuna tree bark powder along with traditional drugs for a period of three months while a control group was given only the cardioprotective and healing drugs. After a period of 3 months, it was found that the group which was given Arjuna bark powder showed significant improvement in heart health specifically strengthening the left ventricle (part of the heart).
In another study, arjuna bark and ashwagandha capsules were given to a group of 40 healthy people for a period of 8 weeks. After 8 weeks it was observed that ashwagandha reduced general heart weakness while arjuna bark was effective in improving cardiovascular endurance. Additionally, Arjuna bark is an excellent antioxidant and anti-inflammatory which helps reduce the stress on heart tissues and slow down any age or lifestyle-related deterioration of heart muscles. However, it is always suggested to talk to your Ayurveda doctor to know the right dosage of Arjuna bark powder for you.
Arjuna herb for cholesterol
Numerous studies have been done to test the hypolipidemic (reducing cholesterol) properties of Arjuna tree bark. Both animal and clinical studies confirm that the bark of the arjuna tree is an excellent agent for balancing the lipid (fat) profile in the body.
In a study, 21 people with coronary heart disease were given 1g of arjuna bark powder with milk for a period of 4 months and it was found that administration of arjuna bark has a positive effect in maintaining the lipid content of the body.
Further studies suggest that arjuna bark reduces the amount of LDL (bad cholesterol) which in turn reduces the risk of atherosclerosis (deposition of fat in arteries) and cardiovascular diseases like stroke and heart attack. So, it’s safe to say that arjuna bark has a bright future as a hypolipidemic.
Arjuna bark for blood pressure
According to ayurvedic doctors, Arjuna bark is very useful for maintaining blood pressure when given in combination therapy with other herbs. Numerous researches have been done to test the usefulness of arjuna bark in reducing blood pressure and they indicate that this ayurvedic claim may be true after all.
In a clinical study, 10 patients with CHF (congestive heart failure, the inability of heart to pump blood efficiently) were given 4g of arjuna bark powder, two times a day for a period of one month. At the end of one month, there was a significant reduction in symptoms of breathlessness and both systolic and diastolic blood pressure.
It is still necessary to check in with your doctor to know the right dosage of arjuna bark powder as per your body type.
Arjuna bark for diabetes
Animal-based models and lab studies claim that Arjuna bark is an excellent hypoglycemic (reduces blood sugar) agent. Studies suggest that arjuna bark increases the uptake of glucose from the blood and inhibits some enzymes involved in glucose production. Thus reducing blood glucose levels.
However, in the absence of human studies, not much can be confirmed about the anti-diabetic effects of this bark on humans.
Arjuna bark for cough
Animal studies hint that arabinogalactan, a chemical compound present in arjuna tree bark is effective in relieving cough symptoms. But, due to lack of human studies, it is best to refer to an ayurvedic doctor to understand the antitussive (cough-relieving) effects of arjuna bark.
Arjuna bark as an anti-coagulant
Research on arjuna bark may be useful as an anticoagulating agent (stops blood clot formation). It was further suggested that this bark could avoid platelet aggregation (collection of clot-forming cells in body) or interfere with some signal that starts blood clotting. However, more studies still need to be done to confirm the anticoagulant effects of arjuna bark.
Arjuna bark for bleeding disorders
In Ayurveda, arjuna bark is extensively used as a remedy for bleeding disorders such as Haemophilia, Von Willebrand disease, unusual and frequents internal bruising and bleeding, heavy menstrual periods and haemorrhages.
According to ayurvedic doctors, arjuna bark is an excellent vasoconstrictor (narrows blood vessels) which leads to reduction in blood loss in case of hemorrhage. However, there is no evident research to prove these effects of arjuna bark in humans.
Arjuna bark for stomach ulcers
Animal studies hint that the methanol extract of arjuna bark reduces the severity of gastric ulcers by strengthening the mucosal barrier in the stomach. But, no human studies have been done so far to confirm similar effects on human. So, if you are suffering from stomach ulcers, it’s better to ask your ayurvedic doctor before taking arjuna bark in any form.
Arjuna bark for fractures
Fractures in bones may be caused due to a sudden force or stress caused by an injury or conditions like osteoporosis. The general line of treatment includes bone substitutes (organic or synthetic substances used to heal broken bones) and growth factors. But, growth factors are quite costly and not without side effects. Ayurvedic doctors use a paste of Arjuna bark to heal fractures. Laboratory studies claim that extracts of Arjuna bark are very effective in the regeneration of bone tissue. But, due to the lack of human-based studies, it is hard to confirm this healing benefit of Arjuna bark.
Arjuna bark antioxidant
Numerous studies have been done to test the antioxidant potential of arjuna bark. Laboratory and animal studies suggest that administration of arjuna bark significantly increases the amount of anti-oxidants like superoxide dismutase, catalase, Vitamin A, C, and E in the liver.
However, no human studies have been done yet to test the antioxidant potential of arjuna tree bark on the human body.
Arjuna bark as an antimicrobial
Aqueous and acetone extracts of arjuna bark have been found to be effective against different strains of Staphylococcus aureus (a type of bacteria), including antibiotic-resistant VRSA and MRSA Staphylococcus.
Another study suggests that instead of being a wide range antibiotic, arjuna bark extracts may be more potent against certain kind of bacteria (gram negative). Due to lack of human studies its best to check with your ayurveda doctor before using arjuna bark for any medical condition.
