HelloPharmacist Scorecard of Yarrow Flower Vanilla Flavor by TerraVita

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.

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 flower glycerite liquid extract. The extract is mixed with glycerin and vanilla flavor as inactive ingredients.

Glycerite means the yarrow has been steeped in glycerin, which is a common way to preserve and administer herbal extracts.

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 in the conditions we've reviewed — tonsillitis, wound healing, eczema, menstrual pain, and vaginal yeast infections — is not yet established in our data. That means clinical evidence either doesn't exist yet or is too limited to draw firm conclusions.

If you're thinking about yarrow for a specific health concern, talk with your pharmacist or doctor about what the current research actually supports.

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, yarrow is generally well tolerated. Topical use is where most side effects show up: dermatitis and allergic skin reactions are the most common, especially in people sensitive to the plant's compounds.

A small number of people have also reported skin reactions from sun exposure (phototoxic dermatitis) or from handling the flowers themselves. Yarrow is not recommended in pregnancy — the evidence suggests it may affect the uterus.

There isn't enough safety data to use it while breastfeeding either. If you're pregnant, planning to become pregnant, or nursing, don't use this product without talking to your doctor.

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 (a mood stabilizer), check with your pharmacist or doctor before using this product — yarrow may raise lithium levels and cause side effects. No other drug interactions are documented for the ingredients 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 has a long traditional use history, but clinical evidence for most of its purported benefits is still lacking. It's a good option to discuss with your pharmacist if you take lithium — that's the main interaction to watch.

If you're pregnant or breastfeeding, skip it. For everyone else, watch for any skin irritation, especially if you apply it topically or handle the flowers.

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 Vanilla Flavor by TerraVita: Common Questions

Does Yarrow Flower Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Yarrow Flower Vanilla Flavor 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 Vanilla Flavor 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.
Is yarrow safe to use while I'm pregnant?
No. Traditional use and safety evidence suggest yarrow may affect the uterus, so it's best avoided in pregnancy. Talk to your doctor before using any herbal product during pregnancy.
Can I use this if I'm breastfeeding?
There isn't enough safety information to recommend yarrow while breastfeeding. It's best to avoid it and talk with your doctor or pharmacist about safer options.
What are the most common side effects?
When taken by mouth, yarrow is generally well tolerated. Topical side effects — like dermatitis or allergic skin reactions — are more common. Some people are sensitive to compounds in the plant that can cause itching or rashes, especially with sun exposure.
Does this work for wound healing or eczema?
The clinical evidence for yarrow in wound healing and eczema isn't established in our data yet. There isn't enough reliable research to say whether it works for these uses.
What's a glycerite?
A glycerite is an herbal extract made by soaking the plant material in glycerin instead of alcohol. It's a gentler way to preserve and administer the herb, and this product uses glycerin as the base.
I take lithium. Can I use this product?
You should check with your doctor or pharmacist first. Yarrow may slow how your body clears lithium, which could raise lithium levels and cause side effects. Your lithium dose might need adjustment.
