HelloPharmacist Scorecard of Sweet Woodruff by TerraVita

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: sweet woodruff glycerite liquid extract. It's a liquid form, which means the herb is dissolved in glycerin for easy dosing.

Sweet woodruff has been used traditionally for various purposes, though the evidence supporting these uses remains limited. The glycerin serves as the inactive carrier that stabilizes and preserves 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 for sweet woodruff's effectiveness is insufficient across the conditions listed in our data—angina, arrhythmia, chronic venous insufficiency (poor circulation in the legs), migraine headache, and respiratory tract infections. That means we don't have reliable studies showing it works for these purposes.

If you're considering it for a specific health concern, talk it over with your doctor to see whether there's better-studied support for other options.

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 full safety evaluation hasn't been completed. The most common side effect reported is headache.

In rare cases and especially at higher doses, it may cause liver disease, stupor (extreme drowsiness), or dizziness. Because sweet woodruff contains coumarin—a compound that can be harmful in larger or long-term doses—caution is advised if you use it regularly or in quantity.

There isn't enough safety data during pregnancy, and use is advised against while breastfeeding.

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 or antiplatelet drugs—such as warfarin, aspirin, clopidogrel, or similar medications—check with your doctor or pharmacist before using sweet woodruff. The interaction is rated Moderate, and although the coumarin content is low, clinically meaningful effects remain uncertain.

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 at typical doses, but evidence for its effectiveness is lacking. The main concern is its potential to interact with blood thinners and antiplatelet drugs due to its coumarin content, though the levels are low.

If you take any clotting medications or are pregnant or breastfeeding, talk with your doctor or pharmacist before starting it.

Does sweet woodruff actually work for anything?
