Arjuna
Ayurveda's heart tonic — arjuna bark has been used for thousands of years to support cardiovascular health. Here's what the modern evidence says, how to dose it, and who it's best for.
Arjuna bark extract strengthens heart muscle function, helps lower blood pressure, and improves cholesterol levels. It's one of the few Ayurvedic herbs with genuine cardioprotective evidence — supporting both the structure and function of your heart.
Good for you if: You have mildly elevated blood pressure, want cardiovascular support, have mild angina, or are looking for a heart-protective supplement with Ayurvedic backing.
Dive deeper into the researchCommon side effects
- May lower blood pressure too much if combined with BP medication
- Can interact with blood thinners — monitor INR
- Mild constipation or stomach upset in some people
What does arjuna do?
Arjuna bark contains compounds called arjunolic acid and arjunetin that directly support heart muscle cells. It has three main cardiovascular effects: it strengthens the heart's pumping ability (inotropic effect), it relaxes blood vessels (reducing blood pressure), and it improves your lipid profile.
In clinical trials, arjuna has shown benefits for people with stable angina, mild heart failure, and high blood pressure. It's not a replacement for cardiac medication, but it's a useful complement.
What can you expect?
- Lower blood pressure — mild to moderate reduction in both systolic and diastolic BP
- Better exercise tolerance — improved cardiac output during activity
- Improved cholesterol — LDL reduction and HDL improvement
- Angina relief — reduced frequency and severity of chest pain episodes
- Heart muscle support — improved left ventricular ejection fraction
How to take it
500 mg arjuna bark extract twice daily — with meals. The traditional method is arjuna bark powder boiled in milk (ksheerpak vidhi), which is believed to enhance absorption.
Allow 8–12 weeks for measurable cardiovascular changes. Get a baseline BP and lipid panel before starting.
Important: If you're on blood pressure medication, beta-blockers, or blood thinners, talk to your doctor before starting arjuna. It can enhance the effects of these drugs.
Which form to buy?
| Capsules/Tablets | Bark powder | Ksheerpak (milk decoction) | |
|---|---|---|---|
| Best for | Convenience & precision | Traditional protocols | Enhanced absorption |
| How much | 500 mg 2x/day | 3–6 g/day in milk | Traditional preparation |
| Cost | ₹150–400/60 tabs | ₹100–250/100g | DIY with powder + milk |
Capsules are most convenient for daily use. The traditional ksheerpak method (boiling bark in milk until it reduces) is considered more effective by Ayurvedic practitioners.

Get early accessFrequently Asked Questions
Is arjuna as good as heart medication?
No — arjuna is a complement to, not a replacement for, prescribed cardiac medication. It has genuine cardioprotective properties, but its effects are milder than pharmaceutical drugs. Never stop prescribed medication in favour of arjuna.
Can arjuna lower blood pressure?
Yes. Multiple studies show mild to moderate BP reduction. This is beneficial if your BP is mildly elevated, but can cause hypotension if combined with BP medication. Monitor your readings and coordinate with your doctor.
How long does arjuna take to show results?
For blood pressure: 4–8 weeks. For cholesterol improvement: 8–12 weeks. For heart function improvement: 12+ weeks. Get baseline measurements and retest to track progress.
Is arjuna safe to take long-term?
Generally yes — arjuna bark has centuries of traditional use. Monitor blood pressure regularly and get periodic liver function tests. Avoid if you have very low blood pressure or are on blood thinners.
How it works in your body
Arjunolic acid and arjunetin (triterpene saponins) have direct cardiotonic effects — they strengthen heart muscle contraction (positive inotropic) while also relaxing blood vessels (vasodilatory). The flavonoids (arjunone, arjunolone) provide antioxidant protection to cardiac tissue. Arjuna also inhibits platelet aggregation and reduces LDL oxidation, addressing two key mechanisms of cardiovascular disease.
What the studies show
- Angina: Reduced angina frequency comparable to isosorbide mononitrate in RCTs
- Heart failure: Improved ejection fraction in patients with mild-moderate CHF
- Blood pressure: Significant systolic and diastolic reduction in hypertensive subjects
- Cholesterol: LDL reduction and HDL improvement in multiple trials
- Exercise tolerance: Improved treadmill exercise time and VO2 max
Side effects & safety
Arjuna is generally well-tolerated, but requires monitoring:
- Low blood pressure — Can drop BP too low, especially combined with BP medication. Monitor regularly.
- Blood thinner interaction — Arjuna has mild antiplatelet activity. Avoid with warfarin or aspirin without medical supervision.
- Constipation — Mild constipation reported in some users.
- Stomach upset — Nausea or discomfort, usually at higher doses. Take with food.
- Thyroid interaction — Some reports of thyroid level changes. Monitor if on thyroid medication.
Who should skip it: People with very low blood pressure, those on blood thinners or beta-blockers (without medical supervision), and pregnant women.
Which labs to check
If you want to track your response properly, get these tested before you start and again at 8–12 weeks:
- Blood pressure — the most important metric to track
- Lipid panel (LDL, HDL, total cholesterol) — arjuna's key measurable benefit
- Liver enzymes (ALT, AST) — periodic monitoring on long-term use
