HelloPharmacist Scorecard of Arjuna 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.

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Arjuna by Herbal Hills contains one active ingredient: Arjuna bark extract blended with Arjuna bark powder. In traditional use, Arjuna has been valued for supporting heart and circulatory function.

The capsules also contain silicon dioxide and an HPMC capsule shell as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Terminalia product and its label doesn't state a use — see Terminalia's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for Arjuna's effectiveness isn't established in our data. Studies have looked at its potential role in high blood pressure, high cholesterol, obesity, and angina, but there isn't enough reliable evidence yet to rate how well it works for any of these.

If you're considering it for a specific health concern, talk it over with your doctor or pharmacist about what the current research shows and whether it's right for you.

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 is generally well tolerated in short-term studies, but long-term safety data is limited and quality can vary between products. The safety information during pregnancy and breastfeeding isn't strong enough to recommend use — the data advises against taking it if you're pregnant or nursing.

If you're in either situation and interested in Arjuna, discuss it with your doctor or pharmacist for personalized guidance.

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 taking Arjuna, double-check with your pharmacist or doctor if you're on any of these: drugs broken down by your liver's CYP3A4, CYP2D6, or CYP2C9 enzymes (a very common group that includes many blood pressure, heart, and psychiatric medications); blood thinners or antiplatelet drugs; diabetes medications; chlorzoxazone (a muscle relaxant); or omeprazole (a reflux medication). No interactions are documented for any other ingredients in this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Arjuna might appeal to you if you're looking for traditional heart and circulatory support — but it has moderate interactions with a very large number of medications, mainly through how your liver processes drugs. If you take any prescription medications at all, check them against this product before starting.

Talk with your own doctor or pharmacist about whether Arjuna fits your health plan.

Arjuna bark extract & Arjuna bark powder Blend7 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 by Herbal Hills: Common Questions

Does Arjuna by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Arjuna 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 contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is Arjuna used for?
Arjuna bark has traditionally been used to support heart and circulatory health. The evidence for specific conditions like high blood pressure, high cholesterol, obesity, and angina isn't established yet in our data, so talk with your doctor about what research currently shows and what's right for your situation.
Can I take Arjuna if I'm pregnant or breastfeeding?
The safety data advises against using Arjuna during pregnancy and breastfeeding because there isn't enough information to know if it's safe. If you're pregnant or nursing and interested in this supplement, discuss it with your doctor or pharmacist.
What are the side effects of Arjuna?
Arjuna is generally well tolerated in short-term studies, and no specific side effects are documented in our data. That said, long-term safety information is limited, so if you notice anything unusual after starting it, mention it to your pharmacist or doctor.
Does Arjuna interact with heart or blood pressure medications?
Arjuna can interact with many medications, including those used for the heart — primarily because it slows how your liver breaks down certain drugs. Before taking Arjuna alongside any prescription medications, check them with your pharmacist or doctor to be sure.
How many capsules are in this product?
That information isn't in our product facts. Check the label on the bottle or contact Herbal Hills directly for details on capsule count and dosing.
Is this product tested for quality and purity?
Our data notes that long-term safety can vary by product, which suggests quality differences exist across brands. For specific quality testing or certifications on this Herbal Hills product, reach out to the manufacturer directly.
