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.

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 a single active ingredient: a liquid extract of certified organic Sweet Woodruff (Galium odoratum) dried herb. The extract is suspended in menstruum, an inactive carrier fluid that helps deliver the herb's compounds.

Sweet Woodruff is a traditional herbal preparation, though the evidence for its specific uses is limited by current standards.

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 on Sweet Woodruff for angina, heart rhythm issues (arrhythmia), chronic venous insufficiency, migraine headache, and respiratory tract infections is currently insufficient to rate — meaning the science hasn't established whether it works for these purposes. We don't have effectiveness data on file for this product's use in other conditions.

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.

Sweet Woodruff is generally well tolerated when used orally in small amounts, though a thorough safety evaluation hasn't been completed. The most common side effect reported in studies is headache.

In larger amounts, it can also cause dizziness or a sedated feeling (stupor). Rarely, liver disease has been reported.

The real safety concern is coumarin content. While the amounts in sweet woodruff are low, the safety data advises caution with larger or long-term doses because coumarin can be harmful over time.

There isn't enough safety data for use during pregnancy, and it's best avoided while breastfeeding.

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.

Before taking Sweet Woodruff, check your blood thinners and antiplatelet drugs with your doctor or pharmacist — this includes medications like warfarin, dabigatran, apixaban, aspirin, and clopidogrel. The herb's coumarin content could theoretically boost their blood-thinning effect and raise bleeding risk, even though the levels in sweet woodruff are low and clinically meaningful interactions are considered doubtful.

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 a traditional herbal extract generally well tolerated in small amounts, but the evidence for its effectiveness hasn't been established. The main caution is for people on blood thinners or antiplatelet medications — the coumarin it contains could theoretically increase bleeding risk, even though the levels are thought to be low.

Talk with your doctor or pharmacist before starting it, especially if you take any clotting-related medication, and avoid it while pregnant or breastfeeding.
