HelloPharmacist Scorecard of Yarrow 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.

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 Herb Extract (dried). Yarrow is a plant traditionally used in herbal medicine for various purposes, though the evidence supporting most of those uses isn't well established.

The liquid also contains alcohol, water, and glycerin as inactive ingredients.

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 reliably works for tonsillitis, wound healing, eczema (atopic dermatitis), menstrual pain (dysmenorrhea), or yeast infections (vaginal candidiasis). Each of these uses is rated as having insufficient reliable evidence to rate.

If you're thinking about yarrow for one of these reasons, that's a conversation to have with your doctor or pharmacist.

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.

Taken by mouth or applied inside the vagina, yarrow is generally well tolerated. However, when applied to the skin, it can trigger allergic or eczema-like dermatitis in some people, due to compounds called sesquiterpene lactones.

It's also been reported to cause reactions to sun exposure, airborne contact dermatitis, and in rare cases, breathing problems. One person in a trial reported acne got worse after vaginal use.

Because safety data are limited and allergic reactions can happen, yarrow is best used short-term and under guidance. Do not use in pregnancy—it's traditionally avoided because it may affect the uterus.

Breastfeeding mothers should avoid it too, as there isn't enough safety information.

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 before adding yarrow—it may increase lithium levels (Moderate severity). No other medication interactions are documented in our data 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 is traditionally used for several conditions, but we don't have solid evidence it works for most of them. If you take lithium, check with your pharmacist before starting.

If you're allergic to plants in the daisy family or have sensitive skin, be cautious—yarrow can trigger skin reactions. Talk to your doctor or pharmacist about whether this makes sense 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 by Herbal Terra: Common Questions

Does Yarrow by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Yarrow 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 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 while pregnant or breastfeeding?
No. Yarrow is traditionally avoided in pregnancy because it may affect the uterus, and the safety data advise against it. There also isn't enough safety information for breastfeeding. Talk to your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.
What are the side effects of yarrow?
When taken by mouth or used vaginally, yarrow is generally well tolerated. When applied to skin, it can cause allergic or eczema-like rashes, reactions to sunlight, and rarely breathing problems if inhaled. One patient in a trial reported worsened acne after vaginal use.
Does yarrow actually work for wound healing or eczema?
The evidence we have doesn't establish that yarrow reliably works for either one. Both are rated as insufficient reliable evidence, meaning we don't have strong proof it helps.
Why is there alcohol in this liquid?
Alcohol is used as a preservative and solvent in liquid herbal extracts to keep the product stable and extract the active compounds from the plant material.
What should I know if I have sensitive skin or allergies to plants?
Yarrow can trigger allergic or eczema-like skin reactions, especially in people sensitive to plants in the daisy family. If you have a history of plant allergies or very reactive skin, patch-test first or talk to your pharmacist before use.
