HelloPharmacist Scorecard of Tansy Plant 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: tansy plant glycerite liquid extract. It's a liquid concentrate of tansy prepared with glycerin.

Inactive ingredients (the base and flavoring) are glycerin and vanilla flavor.

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 Tansy product and its label doesn't state a use — see Tansy'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.

We don't have effectiveness information for tansy on file. The facts we hold don't establish what this product is meant to treat or whether it works for any particular condition.

The evidence, ingredient by ingredient Tansy

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.

Tansy carries serious safety concerns. It contains thujone, a toxic compound — internal use is generally discouraged because of poisoning risk.

Symptoms of thujone toxicity include rapid heartbeat, irregular heartbeat, fast breathing, severe stomach upset, vomiting, dilated pupils, liver damage, kidney damage, and in severe cases, death. As few as 10 drops of tansy oil have been fatal, with death occurring within 1 to 3.5 hours of ingestion.

Tansy is likely unsafe in pregnancy — it has been used traditionally to trigger miscarriage and must not be taken when pregnant. It's also likely unsafe while breastfeeding.

If you're pregnant, planning pregnancy, or breastfeeding, do not use this product.

Side effects, ingredient by ingredient Tansy

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Tansy.
  • The most serious interaction on file is rated Major.
  • 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 drink alcohol, check with your pharmacist before using this product — tansy can intensify alcohol's effects. We haven't documented interactions with other medications in our data, but given tansy's toxicity profile, have a full medication review with us first.
