HelloPharmacist Scorecard of Sweet Woodruff by Hawaii Pharm

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 Sep 17, 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 liquid contains one active ingredient: certified organic sweet woodruff extract. The extract also contains vegetable palm glycerin and pharmaceutical-grade alcohol as inactive ingredients.

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 the data we hold. We have insufficient reliable evidence to rate it for angina, arrhythmia, chronic venous insufficiency, migraine headache, or respiratory tract infections.

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, though a thorough safety evaluation hasn't been done. Headache is the most common side effect reported.

Rarely, liver disease has been reported. Because sweet woodruff's coumarin content can be harmful in larger or long-term doses, it's best used only in small amounts, and safety data during breastfeeding is too limited—the facts advise against use while breastfeeding.

For pregnancy, the safety data we hold is incomplete; talk with your doctor or pharmacist about whether it's right for you.

Side effects, ingredient by ingredient Sweet Woodruff

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 — 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.

If you take blood thinners (anticoagulants or antiplatelet drugs)—like warfarin, aspirin, or clopidogrel—double-check with your pharmacist or doctor before adding this product, because of a theoretical increase in bleeding risk.

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.

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 is sweet woodruff actually used for?
We don't have reliable evidence that sweet woodruff works for angina, arrhythmia, chronic venous insufficiency, migraine, or respiratory tract infections. The evidence just isn't established in the data we hold.
Is it safe to take sweet woodruff long-term?
Sweet woodruff contains coumarin, which can be harmful in larger or long-term doses. It's traditionally used only in small amounts. Because a thorough safety evaluation hasn't been done, long-term use isn't well understood.
What side effects does sweet woodruff cause?
Headache is the most common side effect. In larger amounts, it can also cause stupor or dizziness. Liver disease has been reported rarely.
Can I take sweet woodruff while breastfeeding?
No—the safety data advises against it. There isn't enough information to know it's safe, so it's best avoided while breastfeeding.
Is sweet woodruff safe during pregnancy?
