HelloPharmacist Scorecard of Tansy Plant 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 is a single-ingredient liquid: tansy plant glycerite extract. Glycerin is listed as an inactive ingredient — it's the base that carries the tansy in liquid form.

Tansy is a plant traditionally used in herbal medicine, though it does contain thujone, a compound that requires caution with internal use.

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 ratings on file for tansy in our data, so the evidence supporting its use isn't established from our sources.

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, which is toxic, and internal use is generally discouraged.

The product is rated Likely Unsafe in pregnancy because tansy has been used traditionally to bring on menstruation or abortion — it must not be used if you're pregnant or trying to become pregnant. It's also rated Likely Unsafe while breastfeeding because of the thujone content and lack of safety data.

Adverse effects from tansy — especially from varieties high in thujone — can be severe and include rapid or irregular heartbeat, vomiting, severe stomach irritation, liver and kidney damage, and in rare cases, death. Deaths have been reported from as little as 10 drops of tansy oil, sometimes within hours.

Skin reactions like eczema and light sensitivity have also been reported from contact with tansy and related plants.

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.

Do not combine this product with alcohol — tansy can increase and change alcohol's effects, a Major interaction. We hold no interaction data for other medications, but given tansy's toxicity profile, it's important to check with your pharmacist about your full medication list before starting.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This is a product to approach with real caution. Tansy is not recommended for internal use because of its thujone content and the serious side effects documented with it.

If you're pregnant, planning pregnancy, or breastfeeding, do not use it. Talk with your pharmacist or doctor before considering tansy, especially if you drink alcohol or take any medications.

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 take tansy if I'm pregnant or breastfeeding?
No. Tansy is rated Likely Unsafe in pregnancy because it has been used traditionally to induce miscarriage and is not safe for a developing baby.

What is thujone, and why should I worry about it?
Thujone is a toxic compound naturally present in tansy. It's why internal use of tansy is generally discouraged — even small amounts can cause serious effects like rapid heartbeat, vomiting, severe stomach pain, and damage to the liver and kidneys. In rare cases, people have died from tansy poisoning.
What happens if I take tansy with alcohol?
Thujone in tansy can increase and alter alcohol's effects on your body. This is a Major interaction, so you should avoid combining them. If you drink alcohol, don't use this product without talking to your pharmacist first.
What are the side effects of tansy?
Tansy can cause a rapid or irregular heartbeat, vomiting, severe stomach upset, liver and kidney damage, dilated pupils, and difficulty breathing. Skin contact with tansy can trigger eczema or light sensitivity reactions. In rare but documented cases, toxicity has been fatal.
Is there evidence that tansy works for anything?
We don't have effectiveness ratings on file for tansy, so the evidence supporting its use isn't established in our data.
