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 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: certified organic sweet woodruff extract, supplied as a liquid. The extract also includes vegetable palm glycerin and pharmaceutical-grade alcohol as inactive ingredients — these are the base the herb is mixed into.

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 condition. The data rates all the uses in this supplement — angina, abnormal heart rhythm, chronic venous insufficiency, migraine, and respiratory infections — as having insufficient reliable evidence.

That doesn't mean it doesn't work; it means the research backing it isn't solid enough for us to say one way or the other.

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.

Taken orally in small amounts, sweet woodruff is generally well tolerated. The main side effect reported in trials is headache; larger doses can also cause dizziness or stupor.

Because sweet woodruff contains coumarin, larger or long-term doses carry potential for harm — the safety data notes liver disease as a rare serious adverse effect. A full safety evaluation hasn't been done, so caution is warranted with regular use.

Due to coumarin content and lack of safety data, sweet woodruff is best avoided in pregnancy. We also don't have enough information about breastfeeding safety, so it's best to avoid it while nursing — talk with your doctor or pharmacist for personalized advice if either applies to 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 anticoagulant or antiplatelet drugs — blood thinners like warfarin, dabigatran, apixaban, or antiplatelet medications like aspirin or clopidogrel — check with your pharmacist before starting sweet woodruff. The extract contains coumarin, which may theoretically boost their blood-thinning effects and raise bleeding risk, though the actual risk from the low levels here is unclear.

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 may appeal to someone exploring herbal remedies, but the evidence that it works for any specific condition just isn't there yet. If you take blood thinners or antiplatelet medications, check with your pharmacist first — the coumarin in this extract could theoretically increase bleeding risk, even though the levels are low.

Skip it during pregnancy and breastfeeding, and talk to your pharmacist before regular use.

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 Hawaii Pharm: Common Questions

Does Sweet Woodruff by Hawaii Pharm 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.
Can I take this if I'm on a blood thinner?
Not without checking with your pharmacist first. Sweet woodruff contains coumarin, which might increase the effect of blood thinners and raise bleeding risk — though the levels in this product are low and real harm is unlikely. Your pharmacist can review your specific medication and advise you.
What's the main side effect I should watch for?
Headache is the most common side effect reported. At larger doses, you might also feel dizzy or drowsy. If you get a headache or feel unusual, stop and talk to your pharmacist.
Is this safe to take long-term?
We don't have enough safety data to say for sure. Because sweet woodruff contains coumarin, larger or long-term doses carry potential for harm — including rare serious effects on the liver. Use caution and talk with your pharmacist about how long you should take it.
Can I use this while pregnant or breastfeeding?
No. Due to coumarin content and lack of safety data, sweet woodruff should be avoided in pregnancy and while breastfeeding. Talk with your doctor or pharmacist about alternatives if either applies to you.
Does this actually work for anything?
The evidence we hold doesn't establish that it works for any condition — the data rates all the uses listed as having insufficient reliable evidence. That doesn't prove it doesn't work, just that the research backing it isn't solid enough for us to say either way.
