HelloPharmacist Scorecard of Yarrow Flower by Indiana Botanic Gardens

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 Flowers Extract. It's made from yarrow flowers and suspended in vegetable glycerin and purified water as the inactive base.

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 on what yarrow actually does is incomplete. Our data show insufficient reliable evidence to rate its use for tonsillitis, wound healing, eczema (atopic dermatitis), painful periods (dysmenorrhea), or vaginal yeast infection (candidiasis).

That doesn't mean it doesn't work—it means the studies aren't solid enough yet for us to say either way.

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.

Yarrow taken by mouth or applied vaginally appears to be well tolerated overall, but topical use carries a real risk: it can cause skin irritation, allergic rashes, or hives because of compounds called sesquiterpene lactones in the plant. It's also been linked to sun-triggered skin reactions and, rarely, respiratory symptoms like asthma in people handling the flowers.

One person in a clinical trial reported worsening acne after vaginal use. Because long-term human safety data are scarce, use yarrow short-term and watch for any skin or allergic reactions.

Do not use yarrow in pregnancy—it has traditionally been avoided because it may affect the uterus. There isn't enough safety information to use it while breastfeeding either; talk with your doctor or pharmacist.

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, this is the one to double-check before you start. Yarrow may increase lithium levels in your blood due to diuretic activity, which could mean a dose adjustment 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.

Yarrow is a single-ingredient extract that's generally well tolerated taken by mouth, but topical use can trigger skin reactions in some people. If you take lithium, check with your doctor before starting it.

The evidence for what it treats is still developing, so manage expectations about what it can do for you.

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 Indiana Botanic Gardens: Common Questions

Does Yarrow Flower by Indiana Botanic Gardens 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 yarrow if I'm pregnant?
No. Yarrow has traditionally been avoided in pregnancy because it may affect the uterus. The safety data advise against it, so don't use it during pregnancy.
Is it safe to use while breastfeeding?
There isn't enough safety information to recommend yarrow while breastfeeding. Talk with your doctor or pharmacist about whether it's right for you.
What are the side effects?
Taken by mouth or applied vaginally, yarrow is generally well tolerated. Applied to skin, it can cause dermatitis, allergic rashes, hives, or—in rare cases—sun-triggered skin reactions. One trial participant reported worsened acne after vaginal use. Handling the flowers has occasionally caused nasal congestion and asthma in sensitive people.
Does yarrow really work for eczema, wound healing, or period pain?
The evidence isn't settled yet. We have insufficient reliable data to say whether yarrow works for those uses, so we can't promise it'll help.
Should I avoid this if I have sensitive skin?
Yes—be extra cautious. Yarrow can cause allergic skin reactions and dermatitis in some people, especially if applied topically. If you have a history of plant allergies, start carefully and watch for any irritation.
