HelloPharmacist Scorecard of Sweet Woodruff 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.

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.

Sweet Woodruff Powder by TerraVita Premium Collection contains one active ingredient: sweet woodruff powder itself. There are no inactive fillers or other ingredients listed.

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 Sweet Woodruff product and its label doesn't state a use — see Sweet Woodruff'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 sweet woodruff isn't established in our data. We hold insufficient reliable evidence to rate it for angina, arrhythmia, chronic venous insufficiency, migraine headache, or respiratory tract infections — all conditions it's been studied for.

That doesn't mean it doesn't work; it means the research we have isn't strong enough to make a claim.

The evidence, ingredient by ingredient Sweet Woodruff

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.

Sweet woodruff is generally well tolerated when used in small amounts, as a flavoring. The most common side effect reported is headache; rare but serious adverse effects include liver disease.

However, a full safety evaluation hasn't been done. Because of its coumarin content, larger or long-term doses can be harmful, and safety data during pregnancy and breastfeeding is too sparse — the data advises against use in both.

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

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 — Sweet Woodruff.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 122 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.

Check any blood thinners (anticoagulants) or antiplatelet medications you take — sweet woodruff theoretically increases their effects and bleeding risk, though the coumarin content is low. Altogether, these interactions span 122 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.

Sweet woodruff is generally well tolerated in small amounts, but evidence for any health benefit isn't established in our data. If you take blood thinners or antiplatelet drugs, check your exact medications before you start — the coumarin content theoretically raises bleeding risk, though the amounts here are likely too low to matter clinically.

Avoid it during pregnancy and breastfeeding.

Theoretically, concomitant use might increase the effects of some anticoagulant and antiplatelet drugs and increase the risk of bleeding.
Sweet woodruff contains coumarin and coumarin derivatives. However, the levels of coumarin found in sweet woodruff are so low that clinically relevant effects are doubtful. Until more is known, use with caution.

Sweet Woodruff Powder by TerraVita Premium Collection: Common Questions

Does Sweet Woodruff Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Sweet Woodruff Powder has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sweet Woodruff 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 sweet woodruff safe to take long-term?
The data advises caution with larger or long-term doses because of its coumarin content, which can be harmful over time. A full safety evaluation hasn't been completed, so talk with your pharmacist about your specific use before committing to long-term dosing.
Can I take this while pregnant or breastfeeding?
No — safety data is too sparse, so the data advises against use in both pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized guidance if you're considering this product during these times.
What does sweet woodruff actually do? Does it work?
We hold insufficient reliable evidence to say sweet woodruff works for any of the conditions it's been studied for — angina, arrhythmia, chronic venous insufficiency, migraines, or respiratory infections. That means research so far isn't strong enough to support a claim.
What's coumarin and why does it matter?
Coumarin is a natural compound in sweet woodruff that can thin your blood. The amounts in this product are quite low, so real-world harm is unlikely — but if you're already taking blood thinners, even small additional amounts could theoretically tip the balance toward bleeding.
Will this give me a headache?
Headache is the most common side effect reported with sweet woodruff, especially with larger amounts. If you experience one, stop and talk with your pharmacist.
