HelloPharmacist Scorecard of Arjuna by Herbal Terra

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 Terra contains one active ingredient: certified organic Arjuna dried bark liquid extract (from the tree Terminalia arjuna). The product uses a menstruum — a liquid base — to deliver the extract.

Arjuna bark has been used traditionally to support heart health and circulation.

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, Hypertension, Hyperlipidemia, 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 for Arjuna's effectiveness in the conditions studied is not established in the data we hold. The available research on obesity, high cholesterol (hyperlipidemia), high blood pressure (hypertension), and chest pain (angina) is rated insufficient — meaning either too few studies exist, the studies are too small or of poor quality, or the results don't clearly support a benefit.

If you're considering this product for any of those purposes, talk with your doctor or pharmacist about whether stronger evidence exists elsewhere or whether other options might be better supported.

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 and product quality vary — so if you use it regularly, it's worth checking in with us about what you're taking. There isn't enough safety information to recommend Arjuna during pregnancy or while breastfeeding, so the safety data advises against it in those situations.

If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before using this product.

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 Arjuna, double-check whether you're on any drugs processed by your liver's CYP2D6, CYP2C9, or CYP3A4 enzymes — a category that includes many common medications. Also check if you take blood thinners (anticoagulants) or antiplatelet drugs like aspirin or warfarin, diabetes medications, chlorzoxazone (a muscle relaxer), or omeprazole (a heartburn drug).

Because this product affects so many enzyme pathways, run your full medication list through the checker below.

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.

Arjuna may appeal to someone interested in traditional heart health support, but its broad interactions with liver enzymes make it a product you'll want to clear with a pharmacist first — especially if you take any regular prescriptions. Anyone on blood thinners, diabetes medications, or drugs processed by the liver should be particularly cautious.

Check your exact medications against the interaction tool before starting.

certified organic Arjuna dried bark liquid 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 by Herbal Terra: Common Questions

Does Arjuna by Herbal Terra 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.
Can I take Arjuna if I'm pregnant or breastfeeding?
The safety data advises against it — there isn't enough information to know it's safe in either situation. Talk with your doctor or pharmacist about whether this product is right for you.
Does Arjuna really help with heart health?
The evidence available to us is rated insufficient for the conditions studied — obesity, high cholesterol, high blood pressure, and chest pain. That doesn't mean it doesn't work, just that the proof isn't solid enough yet for us to say. Your doctor can help you weigh whether it's worth trying.
How long can I safely take Arjuna?
Short-term use appears well tolerated in studies, but long-term safety and product quality vary from brand to brand. If you're planning regular or long-term use, check in with your pharmacist about what you're taking.
Why does this product interact with so many medications?
Arjuna's main ingredient inhibits three major enzyme systems in your liver that break down a huge range of drugs. When those enzymes slow down, medications can build up in your blood and cause side effects. That's why we strongly recommend checking your exact medications before you start.
