HelloPharmacist Scorecard of Wormwood 4:1 Extract Powder by TerraVita Premium Collection

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Oct 1, 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.

This product contains one active ingredient: a wormwood extract in powder form, concentrated at a 4:1 ratio. Wormwood is an herb traditionally used for digestive and biliary support.

There are no other inactive ingredients listed.

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 Wormwood product and its label doesn't state a use — see Wormwood'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 on wormwood for the conditions it's used for—biliary disorders, Crohn disease, depression, indigestion (dyspepsia), and osteoarthritis—is insufficient. We don't have reliable data showing it works for any of these in our current information.

If you're considering it for a specific health concern, talk with your doctor or pharmacist about whether the evidence supports its use for your situation.

The evidence, ingredient by ingredient Wormwood

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.

Wormwood contains thujone, a neurotoxic compound that can be harmful, especially in higher amounts or with long-term use. Short-term use of properly prepared products may be acceptable, but the risks increase with dose and duration.

Common side effects from the oil include muscle aches, nausea, and vomiting. Rare but serious effects include acute kidney damage, muscle breakdown (rhabdomyolysis), and seizures.

Chronic use of absinthe—an alcoholic drink containing wormwood—has been linked to addiction, severe gastrointestinal problems, insomnia, hallucinations, tremors, paralysis, and neurological damage. Wormwood is unsafe in pregnancy because it may stimulate the uterus.

There isn't enough safety information to use it while breastfeeding.

Side effects, ingredient by ingredient Wormwood

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 — Wormwood.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: seizure medications.
  • For scale: 50 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 anticonvulsant medications (drugs used to prevent seizures), check your specific medication with the tool on this page before using wormwood. Thujone in the extract may interfere with how these drugs work and increase seizure risk.

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.

Wormwood is not well-studied for the conditions people typically use it for, and it carries real safety concerns, especially with prolonged use or higher doses. The main risk is interaction with seizure medications.

If you take anticonvulsants, or if you're pregnant or breastfeeding, this product isn't appropriate—talk with your doctor or pharmacist before starting it. Even if you don't have those concerns, discuss whether short-term use makes sense for your specific health goals.

Wormwood 4:1 Extract Powder by TerraVita Premium Collection: Common Questions

Does Wormwood 4:1 Extract Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Wormwood 4:1 Extract Powder has a known interaction with 50 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wormwood 4:1 Extract Powder 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 wormwood safe to use while pregnant or breastfeeding?
No. Wormwood is considered unsafe in pregnancy because it may stimulate the uterus. While breastfeeding, there isn't enough safety information, so it's best to avoid it. Talk with your doctor or pharmacist if you're considering it during either of these times.
What are the side effects of wormwood?
Common side effects include muscle aches, nausea, and vomiting from the wormwood oil. Serious but rare effects are acute kidney damage, muscle breakdown, and seizures. Long-term use or high doses increase the risk of these harmful effects.
Does wormwood actually work for the conditions it's marketed for?
The evidence isn't established. We don't have reliable data showing wormwood works for biliary disorders, Crohn disease, depression, indigestion, or osteoarthritis. If you're considering it for one of these, ask your doctor what the actual evidence supports.
What is thujone and why is it a concern?
Thujone is a neurotoxin naturally present in wormwood. In medicinal amounts, it can cause serious nervous system effects, including seizures. It's why wormwood is considered unsafe at higher doses or with long-term use.
Can I use wormwood long-term?
Short-term use of properly prepared wormwood may be acceptable, but long-term use isn't recommended because of thujone toxicity. Chronic consumption has been linked to addiction, hallucinations, tremors, paralysis, and neurological damage.
