HelloPharmacist Scorecard of Yarrow Flower Essence by Flower Essence Services

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

Yarrow Flower Essence contains one active ingredient: an infusion of yarrow flowers (Achillea millefolium) prepared at a 1:6000 concentration. The liquid also holds water and brandy as inactive ingredients (used as carriers and preservatives in flower essences).

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 for yarrow's effectiveness against the conditions it's traditionally used for — including sore throat, wound healing, eczema, painful periods, and yeast infections — is currently insufficient to rate reliably. The data we hold does not establish that this product works for any of these purposes.

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. When applied to the skin, however, it can trigger allergic or contact dermatitis (skin inflammation and itching) in some people, especially those sensitive to plants in the daisy family.

Rare reports include sun-triggered skin reactions and, in one case, breathing trouble in someone handling the flowers. Because human safety data are limited overall, allergic reactions remain a concern.

Yarrow should not be used during pregnancy — traditional use has avoided it because it may affect the uterus. There isn't enough safety information to recommend it while breastfeeding either; talk with your doctor or pharmacist about whether it's right for you if you're pregnant or nursing.

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, do not start this product without checking with your pharmacist or doctor first. Yarrow may increase lithium levels, and your dose may need adjustment.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Yarrow Flower Essence is a traditional herbal preparation with very limited evidence for any specific health benefit. If you take lithium, you'll need to check with your pharmacist first.

Even if you don't take lithium, allergic skin reactions are possible, and pregnancy or breastfeeding are reasons to avoid it. Talk to your pharmacist before starting, especially if you have a history of plant allergies.

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 Essence by Flower Essence Services: Common Questions

Does Yarrow Flower Essence by Flower Essence Services interact with any medications?
Yes. Based on its ingredients, Yarrow Flower Essence 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 Essence 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 or breastfeeding?
No, yarrow should not be used during pregnancy because it may affect the uterus. There also isn't enough safety information to recommend it while breastfeeding. Talk with your doctor or pharmacist about safer options.
Does this product actually work for wound healing or other uses?
The evidence available to us doesn't reliably support yarrow for wound healing, eczema, sore throat, painful periods, or yeast infections. More research would be needed to establish whether it's effective.
What are the side effects?
When taken by mouth, yarrow is generally well tolerated. Applied to the skin, it can cause allergic or irritant dermatitis (itching and inflammation), especially in people sensitive to daisy-family plants. Rarely, it may trigger sun-triggered skin reactions or breathing trouble in sensitive individuals.
Is this safe to use long-term?
Yarrow is traditionally used short-term, and human safety data for long-term use are limited. It's best discussed with your pharmacist before you start, especially if you plan to use it regularly.
Can I use this if I'm allergic to ragweed or other plants?
Yarrow belongs to the daisy family, so people with allergies to ragweed, chrysanthemums, or related plants may have allergic reactions to yarrow. If you have known plant allergies, check with your pharmacist first.
