HelloPharmacist Scorecard of Sweet Woodruff 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.

This product contains one active ingredient: a liquid extract of dried Sweet Woodruff herb. The menstruum (the liquid used to extract the herb) is an inactive ingredient that helps deliver the extract.

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 we hold doesn't establish that sweet woodruff works for any of the conditions it's traditionally used for — angina, heart arrhythmia, chronic venous insufficiency, migraine headache, or respiratory tract infections all fall into insufficient evidence. That doesn't mean it doesn't work; it means the science isn't there yet to confirm it.

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.

Orally, sweet woodruff is generally well tolerated, but a full safety review hasn't been done. Headache is the most common side effect.

In rare cases and especially at larger doses, it can cause liver disease, stupor, or dizziness. Because sweet woodruff contains coumarin — a compound that can be harmful in larger or long-term doses — the safety data advises against use during pregnancy and breastfeeding.

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 — 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 your medications before starting if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel). The herb contains coumarin, which could theoretically increase their effects and bleeding risk.

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 traditionally used for circulation and headache, but the evidence for those uses isn't established yet. If you take blood thinners or antiplatelet drugs, talk with your pharmacist before using it — the coumarin content is low, but caution is warranted.

Avoid it during pregnancy and breastfeeding.

Anticoagulant/Antiplatelet Drugs

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 by Herbal Terra: Common Questions

Does Sweet Woodruff by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Sweet Woodruff 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 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's in this sweet woodruff extract?
It's made from dried sweet woodruff herb in liquid form. The only other ingredient is the menstruum, a liquid used to extract the herb's compounds.
Does sweet woodruff actually work for migraine or circulation problems?
The evidence we have isn't enough to confirm it works for migraine, circulation problems, or any of the other conditions it's traditionally used for. More research is needed.
What side effects should I watch for?
Headache is the most common one. In larger amounts, sweet woodruff can cause dizziness or stupor. In rare cases, it may cause liver damage, so don't use it long-term without talking to your pharmacist.
Is it safe if I'm pregnant or breastfeeding?
No — the safety data advises against use during pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice if you're considering it.
Why does coumarin matter if the levels are low?
Coumarin is a compound in sweet woodruff that can thin the blood and increase bleeding risk, especially with certain medications. Even though the levels here are low, we recommend caution if you take blood thinners.
