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.

Tansy Plant 450 mg contains one active ingredient: tansy herb. The product comes in a capsule with gelatin and 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 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 established effectiveness ratings for tansy in our data, so we can't tell you what the evidence says it does or doesn't do.

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 contains thujone, a naturally occurring compound that can be toxic. The safety data advises strongly against internal use of tansy — it's not recommended as a supplement you take by mouth.

Thujone toxicity can cause a rapid or irregular heartbeat, fast breathing, severe nausea and vomiting, dilated pupils, and liver or kidney damage. Deaths have been reported from very small amounts of tansy oil.

Tansy must not be used in pregnancy, as it has traditionally been used to bring on menstruation or abortion. The safety data also advises against use while breastfeeding because thujone content makes it unsafe.

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.

Alcohol is the one medication type with a documented Major severity interaction: thujone in tansy can increase and alter alcohol's effects. If you drink, check with your pharmacist before starting this product.

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.

Because tansy contains thujone, a toxic compound, internal use is generally not recommended by safety data. If you're considering this product, talk with your pharmacist or doctor first — this is not a supplement to take on your own.
