HelloPharmacist Scorecard of Yarrow 2,000 mg by Nature's Answer

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 aerial parts extract (the above-ground parts of the yarrow plant), supplying 2,000 mg per serving. The liquid is made with water, vegetable glycerin, and alcohol 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 is effective for the conditions it's traditionally used for — tonsillitis, wound healing, eczema, period pain, and vaginal yeast infections all carry a rating of insufficient reliable evidence. That doesn't mean it doesn't work; it means the clinical data aren't strong enough yet for us to rate it one way or another.

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 vaginally, yarrow is generally well tolerated. However, when applied to skin, it can cause dermatitis (itching and irritation) in some people, along with rare reports of allergic reactions and sun-sensitivity reactions.

Inhaling yarrow dust or handling the flowers has occasionally triggered sinus and asthma symptoms in sensitive individuals. The safety data are limited because yarrow is usually used short-term and for brief periods only.

Don't use yarrow during 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 before use if you're pregnant, planning pregnancy, 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 for bipolar disorder, talk to your pharmacist or doctor before starting yarrow. Yarrow may increase lithium levels in your blood, and your dose might need adjustment.

If you take any other prescription medications, use the interaction checker below to be sure.

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 has a long history of use, but the clinical evidence for most of its traditional uses is still thin. It's generally well tolerated when taken by mouth, but skin applications can trigger dermatitis in sensitive people.

If you take lithium, check with your pharmacist first — this supplement could affect your blood levels. For any other prescription medications, run them through the checker on this page.

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 2,000 mg by Nature's Answer: Common Questions

Does Yarrow 2,000 mg by Nature's Answer interact with any medications?
Yes. Based on its ingredients, Yarrow 2,000 mg 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 2,000 mg 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 — don't use yarrow during pregnancy. It's traditionally been avoided because it may affect the uterus. There also isn't enough safety data to use it while breastfeeding. Talk with your doctor or pharmacist about what's safe for you.
What are the side effects of yarrow?
When taken by mouth or applied vaginally, yarrow is well tolerated by most people. When applied to skin, the main risk is dermatitis (itching and rash), especially in people with sensitive skin. Handling the fresh flowers or inhaling the dust can rarely trigger sinus or asthma symptoms.
Does yarrow actually work for wound healing or eczema?
We don't have enough reliable clinical evidence yet to say whether it works for those purposes. Yarrow has a long traditional use, but modern research hasn't established its effectiveness for wound healing, eczema, period pain, or the other conditions it's been used for.
What is yarrow and what is it used for?
Yarrow is an herb — this product contains the extract from the aerial parts (stems, leaves, and flowers). Traditionally it's been used for tonsillitis, wound healing, eczema, period pain, and vaginal yeast infections, though the clinical evidence for these uses is still limited.
Is this product safe to take with my other medications?
The only medication type we have documented interaction data for is lithium. If you take lithium, you need to check with your pharmacist first. For any other prescription or over-the-counter medications, use the interaction checker on this page to be sure.
