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 powder. Tansy is a flowering plant that's been used in traditional medicine, though modern safety data advises caution with internal use because of its thujone content — a compound that can be toxic at certain doses.

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 hold no effectiveness ratings for tansy in our data. The evidence for what it may do is not established here.

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, which carries serious safety concerns. Internal use is generally discouraged because thujone can be poisonous; symptoms of thujone toxicity include a rapid or irregular heartbeat, rapid breathing, severe stomach upset, vomiting, dilated pupils, and damage to the liver and kidneys.

Deaths have been reported from doses as small as 10 drops of tansy oil, sometimes within 1 to 3.5 hours. Tansy must not be used in pregnancy — it has been used traditionally to bring on menstruation or cause abortion.

Safety is not established while breastfeeding, and the thujone content makes it unsafe. Topical contact may cause skin reactions like eczema or sensitivity to sunlight in some people.

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 tansy with alcohol — thujone can increase and alter alcohol's effects (Major interaction). Before taking this product, speak with your pharmacist about the serious safety profile, particularly the risk of thujone toxicity.
