HelloPharmacist Scorecard of Wormwood by L.A. Naturals

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 Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

This product contains one active ingredient: certified organic wormwood. Wormwood is a plant traditionally used in herbal medicine, though the evidence supporting its effectiveness for specific conditions remains limited.

The liquid form also includes grain alcohol and deionized 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 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 supporting wormwood for biliary disorders, Crohn disease, depression, dyspepsia (indigestion), and osteoarthritis is not established in the data we hold. All the conditions listed show insufficient reliable evidence to rate its effectiveness.

If you're considering wormwood for one of these reasons, talk with your pharmacist or doctor about whether there's a better-studied option.

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 neurotoxin that can cause problems, especially in higher doses. Common side effects from the oil include muscle aches, nausea, and vomiting.

Rare but serious effects include acute kidney toxicity, muscle breakdown (rhabdomyolysis), and seizures. Chronic heavy use has been linked to absinthism — a condition marked by tremors, hallucinations, paralysis, brain damage, and psychiatric disease.

Wormwood is considered unsafe during pregnancy because it may stimulate the uterus. There isn't enough safety data to use it while breastfeeding.

The safety data advises against both.

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.

Double-check any anticonvulsant or anti-seizure medication (such as phenytoin, levetiracetam, or valproic acid) before taking wormwood. Thujone in this product may interfere with how well these drugs work.

Altogether, these interactions span 50 individual medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Wormwood is a traditional herbal remedy, but the evidence for what it actually does is thin, and the safety concerns — especially thujone toxicity — are real. If you take anticonvulsant medications, you'll need to check before using this.

Pregnant or breastfeeding? Avoid it.

Talk with your pharmacist about whether this fits your needs and any medications you're on.

Wormwood by L.A. Naturals: Common Questions

Does Wormwood by L.A. Naturals interact with any medications?
Yes. Based on its ingredients, Wormwood 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 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 it safe to take wormwood if I'm pregnant?
No. Wormwood is considered unsafe during pregnancy because it may stimulate the uterus. If you're pregnant or planning to become pregnant, avoid this product.
Can I use wormwood while breastfeeding?
No. There isn't enough safety information available, so it's best to avoid wormwood while breastfeeding.
What are the most common side effects?
The oil from wormwood leaves can cause muscle aches, nausea, and vomiting. These are the most common adverse effects when used in medicinal amounts.
Does wormwood really work for digestive problems or arthritis?
The evidence we hold doesn't support wormwood for dyspepsia, osteoarthritis, Crohn disease, or other conditions listed here — the ratings are all insufficient evidence. Talk with your pharmacist about options with better research behind them.
What's thujone, and why does the label mention it?
Thujone is a neurotoxic compound naturally found in wormwood. At higher doses, it can cause serious side effects including kidney toxicity, seizures, and brain damage — which is why the safety notes caution against it and why short-term use of properly prepared products is advised over longer or stronger doses.
