HelloPharmacist Scorecard of Tarragon Leaf Powder by TerraVita Premium Collection

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

This product contains one active ingredient: tarragon powder. The powder form delivers the herb without any other inactive ingredients listed — it's tarragon and nothing else.

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 Tarragon product and its label doesn't state a use — see Tarragon'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 on tarragon for postoperative nausea and vomiting (PONV) — the condition it's typically used for — is insufficient. We don't have reliable data yet to say whether it works for that purpose.

The evidence, ingredient by ingredient Tarragon

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 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.

Tarragon used in food amounts is generally well tolerated, but concentrated extracts and essential oils should be used cautiously because of a compound called estragole that they contain. Adverse effects have not been reported in available data, though a complete safety review hasn't been done.

Animal research has raised a theoretical concern that long-term estragole consumption might increase cancer risk, but this has only been seen in animals — not yet shown in people. During pregnancy, medicinal or concentrated amounts of tarragon are advised against; food amounts are likely okay, but data are limited.

While breastfeeding, there isn't enough reliable information — talk with your pharmacist or doctor for personalized guidance.

Side effects, ingredient by ingredient Tarragon

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 — Tarragon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 359 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 product, double-check it with blood thinners and antiplatelet drugs (like aspirin or Plavix), CNS depressants (antihistamines, benzodiazepines, tricyclic antidepressants), and MAOIs — all are Moderate-severity interactions. Altogether, these interactions span 359 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This single-ingredient powder is straightforward to use, but it does carry documented Moderate interactions with blood thinners, sedating medications, and a class of antidepressants (MAOIs). If you take any of those, check with your pharmacist first.

Pregnancy and breastfeeding call for a conversation with your doctor or pharmacist too.

Tarragon, Powder3 drug types · 359 drugs

Anticoagulant/Antiplatelet Drugs

Evidence from in vitro research suggests that tarragon extract inhibits platelet aggregation and adhesion. Theoretically, tarragon might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Cns Depressants

Evidence from animal research suggests that tarragon essential oil can cause sedation and motor impairment when administered intraperitoneally at a dose of 1 mL/kg. Theoretically, concomitant use of tarragon with CNS depressants, including antihistamines, barbiturates, benzodiazepines, and tricyclic antidepressants, may increase sedative and other adverse effects.

Likelihood Possible Evidence D
Monoamine Oxidase Inhibitors (Maois)

In vitro research suggests that tarragon extract inhibits monoamine oxidase (MAO)-A and MAO-B enzymes. Theoretically, concomitant use with MAOIs might increase the effects and adverse effects associated with MAOIs.

Tarragon Leaf Powder by TerraVita Premium Collection: Common Questions

Does Tarragon Leaf Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Tarragon Leaf Powder has a known interaction with 359 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Tarragon Leaf Powder 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.
Is tarragon powder safe to use in cooking?
Yes — food amounts of tarragon are generally well tolerated. The caution applies to concentrated extracts and essential oils, which contain higher levels of estragole.
Can I take this if I'm on a blood thinner like warfarin?
No — check with your pharmacist or doctor first. Tarragon can slow blood clotting, and combining it with blood thinners raises your bleeding risk.
What is estragole and why does it matter?
Estragole is a compound naturally present in tarragon. Concentrated extracts and essential oils contain higher amounts of it. Animal research suggests long-term exposure to estragole might increase cancer risk, though this hasn't been shown in people yet.
Is tarragon safe during pregnancy?
The safety data advises against medicinal or concentrated amounts during pregnancy. Food amounts are likely okay, but there's limited data. Talk with your doctor or pharmacist for personalized advice.
Can tarragon help with nausea after surgery?
That's a common use, but the evidence we have is insufficient to say whether it works. You'll want to ask your doctor about options for postoperative nausea.
