HelloPharmacist Scorecard of Yarrow Flower 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.

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: Yarrow Flower Glycerite Liquid Extract. It's made from yarrow flowers prepared in a glycerin base, which is a traditional way to preserve herbal extracts.

Glycerin is also the only inactive ingredient listed.

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 Yarrow product and its label doesn't state a use — see Yarrow'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 yarrow works reliably for any of its traditional uses—including sore throat (tonsillitis), wound healing, eczema, period cramps (dysmenorrhea), or vaginal yeast. For all of these, the data rated the evidence as insufficient to say whether it helps.

If you're considering yarrow for one of these reasons, talk with your pharmacist or doctor about what the science actually supports.

The evidence, ingredient by ingredient Yarrow

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.

When taken by mouth or applied inside the vagina, yarrow is generally well tolerated. Topically (on skin), the main risk is allergic reaction or dermatitis due to its sesquiterpene lactone compounds.

In rare cases, handling or inhaling yarrow can trigger asthma or rhinitis. The safety data advises against using yarrow in pregnancy because it may affect the uterus.

There isn't enough safety information for breastfeeding, so it's best avoided then too. If you're pregnant or nursing, don't use this product.

Side effects, ingredient by ingredient Yarrow

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 — Yarrow.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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 lithium, double-check with your pharmacist or doctor before starting yarrow—this is a Moderate-severity interaction that may require a dose adjustment. No other medication interactions are documented for the ingredient we could check.

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.

Yarrow Flower Liquid Extract is one to check with your pharmacist, especially if you take lithium. The evidence for what it actually treats isn't solid yet.

It's generally well tolerated by mouth, but skin contact can trigger allergic reactions in some people, and it's not safe in pregnancy or while breastfeeding.

Lithium

Theoretically, taking yarrow with lithium might increase the levels and adverse effects of lithium.
Animal research shows that yarrow has diuretic activity. Theoretically, due to these potential diuretic effects, yarrow might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Yarrow Flower by TerraVita: Common Questions

Does Yarrow Flower by TerraVita interact with any medications?
Yes. Based on its ingredients, Yarrow Flower has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Yarrow Flower 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 use this if I'm pregnant or breastfeeding?
No. The safety data advises against yarrow in pregnancy because it may affect the uterus, and there isn't enough safety information for breastfeeding. Talk with your doctor if you're considering herbal remedies while pregnant or nursing.
Does yarrow actually work for wound healing or eczema?
The evidence we hold doesn't establish that it does. For wound healing, eczema, sore throat, period cramps, and yeast—all traditional uses—the data rated the evidence as insufficient to say whether it helps.
What are the side effects of taking yarrow by mouth?
When taken orally, yarrow is generally well tolerated and doesn't appear to cause major side effects in the data we hold. The main risk is allergic reaction, which can happen with any herbal product.
Can I use this on my skin?
Be cautious. Yarrow applied topically can cause allergic dermatitis, hives, or sun-related skin reactions in some people due to its sesquiterpene lactone compounds. In rare cases, handling it can trigger asthma or sinus symptoms.
What is glycerite, and why is it in this product?
Glycerite means the yarrow is extracted and preserved in glycerin, which is a natural sweet liquid. It's a traditional way to make herbal extracts shelf-stable and easier to take by mouth.
