HelloPharmacist Scorecard of Yarrow by Ra Herbals

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

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, a traditional herbal remedy. The liquid form also includes cane alcohol and distilled water 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 for yarrow isn't established in our data. We hold effectiveness ratings for several traditional uses — tonsillitis, wound healing, atopic dermatitis (eczema), painful periods (dysmenorrhea), and yeast infections — but all are rated as insufficient reliable evidence to rate.

That means the research either isn't there yet or hasn't been rigorous enough to draw firm conclusions.

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 used vaginally, yarrow appears to be well tolerated overall. However, topical use carries a real risk: it can cause allergic or atopic skin inflammation (dermatitis) or hives, and has been reported to trigger sun-sensitivity reactions and contact dermatitis from handling the flowers.

One person in a trial developed worsened acne after vaginal use. Yarrow is rated likely unsafe in pregnancy because it may affect the uterus — do not use during pregnancy.

There isn't enough safety data to recommend it while breastfeeding, so it's best avoided then too. Allergic reactions are possible, so if you have known sensitivities to ragweed or related plants, be cautious.

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, check with your doctor or pharmacist before using this product — yarrow may increase lithium levels and side effects, and your dose might need to change.

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 liquid used traditionally for various conditions, but the evidence for those uses isn't established in our data. The main concern is its interaction with lithium; if you take that medication, check with your doctor or pharmacist before starting.

It's not safe in pregnancy and should be avoided while breastfeeding. For anyone else without lithium use, talk it over with your healthcare provider to see if it's right 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.
