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

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: Sweet Woodruff Herb Extract, delivered in a liquid form. The inactive ingredients are alcohol, water, and glycerin—common solvents and preservatives in liquid herbal extracts.

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. It's listed for several conditions—angina, arrhythmia, chronic venous insufficiency, migraines, and respiratory tract infections—but each has insufficient reliable evidence to rate how well it actually works for these purposes.

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 headache is the most commonly reported side effect. In rare cases, liver disease has been reported.

Because sweet woodruff's coumarin content can be harmful at larger or long-term doses, and safety data is limited, caution is advised—especially at higher amounts. The safety data advises against use while breastfeeding, and there isn't enough information on file about its use in pregnancy to know either way; talk with your doctor or pharmacist for personalized advice if you're pregnant or planning to become pregnant.

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 any anticoagulant or antiplatelet drugs—blood thinners like warfarin or aspirin, or drugs that prevent clots—check your specific medication with the tool on this page before starting. While coumarin levels in sweet woodruff are typically low, the interaction is documented and caution is needed.

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 in herbal medicine, but we don't have solid evidence it works for the conditions it's marketed for. If you take blood thinners or antiplatelet drugs, check your exact medications before starting this product.

Because coumarin can build up with long-term use, don't use large amounts or take it for extended periods without talking to your pharmacist first.

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.
What's in this liquid?
Sweet Woodruff Herb Extract as the active ingredient, plus alcohol, water, and glycerin as the liquid base.
Does sweet woodruff actually work for migraines, angina, or the other conditions it mentions?
The evidence isn't solid enough to say. All the conditions listed—migraines, angina, chronic venous insufficiency, arrhythmia, and respiratory infections—are marked insufficient evidence, meaning we don't have reliable data on how well it works for them.
What side effects should I watch for?
Headache is the most common side effect reported. In rare cases, liver disease has been documented. Because the herb contains coumarin, which can be harmful in larger or long-term doses, avoid taking high amounts or using it for extended periods without guidance.
Is it safe to use while I'm breastfeeding?
The safety data advises against use while breastfeeding. If you're nursing or planning to, talk with your doctor or pharmacist before starting.
Can I take this if I'm pregnant?
There isn't enough information on file to know either way. Talk with your doctor or pharmacist for advice tailored to your pregnancy.
