HelloPharmacist Scorecard of Arjunahills 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.

Arjunahills contains one active ingredient: arjuna bark extract and arjuna bark powder blend. In traditional use, arjuna (Terminalia arjuna) is taken to support heart health and circulation.

The product also contains inactive ingredients—magnesium stearate, silica, and a gelatin capsule—that help hold and deliver the active ingredient.

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 2 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 for arjuna's effectiveness in the conditions it's traditionally used for isn't established in the data we hold. Studies looking at its use for obesity, high cholesterol, high blood pressure, and angina all rate as having insufficient reliable evidence to make a clear claim.

That doesn't mean it doesn't work—it means the research backing these uses isn't solid enough yet to say.

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 are limited and quality varies between products. There isn't enough safety information to recommend using this supplement during pregnancy or while breastfeeding, so it's best to avoid it in both cases.

No adverse effects were documented in our data, though that's not a guarantee none have been reported elsewhere.

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 this product, double-check with your doctor or pharmacist if you take any drugs metabolized by CYP2D6, CYP2C9, or CYP3A4 enzymes (a very common group); blood thinners or antiplatelet drugs like warfarin or aspirin; diabetes medications; chlorzoxazone; or omeprazole. All of these carry Moderate-severity interactions with arjuna.

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.

Arjunahills is a single-ingredient arjuna supplement often taken for heart and circulation support, but the evidence for those benefits isn't solid. Because arjuna can slow how your liver clears many common medications—and may also increase bleeding risk with blood thinners or lower blood sugar with diabetes drugs—you'll want to check your exact prescriptions and over-the-counter medications with your doctor or pharmacist before starting it.

Avoid it if you're pregnant or breastfeeding.

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.

Arjunahills by Herbal Hills: Common Questions

Does Arjunahills by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Arjunahills 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?
Arjunahills 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.
Can I take Arjunahills if I'm pregnant or breastfeeding?
No. There isn't enough safety information for either pregnancy or breastfeeding, so it's best to avoid it in both cases. Talk with your doctor or pharmacist about other options if you need heart or circulation support during this time.
What is arjuna bark used for?
Arjuna is traditionally used to support heart health and circulation. However, the evidence backing these uses isn't strong enough yet to make a confident claim about how well it actually works.
Does Arjunahills have any side effects?
No adverse effects were documented in our data. That said, it's generally well tolerated in short-term use, though long-term safety and product quality vary depending on the brand.
Why does this product interact with so many medications?
Arjuna bark slows down the liver enzymes (CYP2D6, CYP2C9, and CYP3A4) that break down hundreds of common medications—everything from antidepressants to blood pressure drugs to painkillers. That's why the interaction count is so high, even though it's just one ingredient.
Is this supplement safe to take with my blood thinner?
No—arjuna can increase bleeding risk when paired with blood thinners or antiplatelet drugs. Check with your doctor or pharmacist about your specific medication before adding this supplement.
