What is Arjuna (Terminalia arjuna)?

Arjuna is the bark of the Terminalia arjuna tree, traditionally used in Ayurveda as a heart tonic. It is commonly taken as a powder or standardized extract.

What are the main benefits of Arjuna for cardiovascular health?

Research suggests Arjuna may support heart function and may help with symptoms such as angina in some people. It may also support healthy blood pressure and lipid profiles, though evidence is not definitive.

What is a typical Arjuna dosage?

A common supplemental range is 500–1500 mg per day of Arjuna extract, depending on the product and concentration. Follow the label and consult a clinician for individualized dosing.

Is Arjuna safe, and who should be cautious?

Arjuna is generally well tolerated at typical doses, but some people may experience digestive upset. Use caution and seek medical advice if you have a heart condition, low blood pressure, a bleeding disorder, or take anticoagulant or antiplatelet medicines.

Can Arjuna improve exercise tolerance in heart failure?

Small clinical studies suggest Arjuna may improve exercise tolerance and some measures of cardiac function in people with heart failure. It should not replace prescribed heart failure treatment and should be used only with medical supervision.
