HelloPharmacist Scorecard of Arjuna Capsules by Herbal Hills

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • “Arjuna Bark Blend, Powder” is a proprietary blend — the label gives one combined amount (250 mg) without saying how much of each component you get.

Arjuna Capsules contains 3 active ingredients. The main one is arjuna bark extract, a traditional botanical ingredient.

The product also includes a tannin component and arjunic acid. These are delivered in veggie capsules with silicon dioxide (an anti-caking agent) as inactive ingredients.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Terminalia's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Heart health and circulation support.
  • We looked for evidence on: Angina, Coronary heart disease (CHD), Heart failure, Hyperlipidemia, Hypertension, Cardiovascular function — and 1 related terms.
  • The closest evidence on file: Terminalia is rated "Insufficient Reliable Evidence To Rate" for Angina (Natural Medicines).
  • Also on file: Terminalia is rated "Insufficient Reliable Evidence To Rate" for Coronary heart disease (CHD), Heart failure, Hyperlipidemia, Hypertension.

The evidence we hold doesn't establish that arjuna is effective for the conditions it's traditionally used for. Its effectiveness for obesity, high cholesterol, high blood pressure, and angina is rated as insufficient reliable evidence to rate — meaning the research so far isn't robust enough for us to make a confident claim either way.

The evidence, ingredient by ingredient Terminalia

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Arjuna bark extract is generally well tolerated in short-term studies, but we don't have solid data on long-term safety, and product quality varies widely. The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know whether it's safe in those situations.

Side effects, ingredient by ingredient Terminalia

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Terminalia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 934 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this, check with your pharmacist if you're on blood thinners or antiplatelet drugs (like warfarin or clopidogrel), diabetes medications, omeprazole for heartburn, chlorzoxazone for muscle pain, or any drug that your liver breaks down — a very common situation. Arjuna bark extract can raise levels of many medications and increase bleeding risk.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

If you're interested in traditional heart-health or cholesterol supplements, this one has a long history of use — but the evidence for how well it actually works isn't established yet. If you take any medications that your liver metabolizes, blood thinners, diabetes drugs, or the specific medications mentioned in our med watch section, talk with your pharmacist before starting.

Arjuna Bark Extract7 drug types · 933 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of Terminalia arjuna with anticoagulant or antiplatelet drugs may increase the risk of bleeding in some patients.
In vitro, Terminalia arjuna bark extract inhibits platelet aggregation, decreases platelet activation, and shows antithrombotic properties.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of Terminalia bellirica or Terminalia chebula with antidiabetes drugs could affect blood sugar control and increase the risk of hypoglycemia.
Animal and in vitro research shows that Terminalia bellirica and Terminalia chebula fruit and seed extract have hypoglycemic effects.

Likelihood Possible Evidence D
Chlorzoxazone (Parafon Forte, Paraflex)

Theoretically, use of Terminalia chebula may increase the risk of adverse effects from chlorzoxazone.
Animal research shows that enteral administration of Terminalia chebula for 15 days prior to administration of chlorzoxazone increases blood levels of chlorzoxazone and decreases chlorzoxazone clearance. It is speculated that Terminalia chebula reduces the metabolism of chlorzoxazone by inhibiting cytochrome P450 2E1.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP2C9 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP2C9 enzymes and reduces CYP2C9 substrate metabolism.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP2D6 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP2D6 enzymes and reduces CYP2D6 substrate metabolism.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP3A4 enzymes and reduces CYP3A4 substrate metabolism.

Likelihood Possible Evidence D
Omeprazole (Prilosec)

Theoretically, use of Terminalia chebula may increase the risk of adverse effects from omeprazole.
Animal research shows that enteral administration of Terminalia chebula for 15 days prior to administration of omeprazole increases blood levels of omeprazole and decreases omeprazole clearance. It is speculated that Terminalia chebula reduces the metabolism of omeprazole by inhibiting cytochrome P450 2C19.

Arjuna Capsules by Herbal Hills: Common Questions

Does Arjuna Capsules by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Arjuna Capsules has a known interaction with 933 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Arjuna Capsules contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is arjuna safe to take during pregnancy or while breastfeeding?
No. The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know whether it's safe. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding and interested in this supplement.
Does this product actually work for heart health or cholesterol?
We don't have strong enough evidence to say. Effectiveness for obesity, high cholesterol, high blood pressure, and angina is all rated as insufficient reliable evidence — meaning the research so far doesn't give us a confident answer.
What's in this product besides the active ingredient?
The capsules themselves are made from vegetables, and there's silicon dioxide, which is an anti-caking agent. There are no unnecessary fillers.
Should I be concerned about long-term use?
The safety data shows arjuna is generally well tolerated short-term in studies, but we don't have good long-term safety information. Additionally, the quality of arjuna products varies by brand, so talk with your pharmacist about which products are more reliable.
I'm taking a muscle relaxer (chlorzoxazone) for a sore back. Can I take this?
No — this supplement may increase levels of that medication, raising the risk of side effects. Check with your pharmacist before adding any new supplement to your routine.
