HelloPharmacist Scorecard of Wormwood by Herb Pharm

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 contains one active ingredient: wormwood flowering aerial parts extract, made from fresh, undried plant material. The liquid is delivered in cane alcohol.

Wormwood has been used traditionally for digestive and inflammatory concerns, though we'll cover what the evidence actually shows below.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Wormwood's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: gastrointestinal system restoration.
  • We looked for evidence on: Crohn disease, Dyspepsia, Gastritis, indigestion, digestive upset, appetite.
  • The closest evidence on file: Wormwood is rated "Insufficient Reliable Evidence To Rate" for Crohn disease (Natural Medicines).
  • Also on file: Wormwood is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Gastritis.

The evidence for wormwood is limited. Our data shows insufficient reliable evidence to rate its effectiveness for biliary disorders, Crohn disease, depression, dyspepsia (indigestion), or osteoarthritis.

That means the studies we have aren't robust enough yet to say whether it truly works for these purposes.

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 be harmful, especially in higher amounts or with long-term use. The most common side effects from the oil are diffuse muscle aches, nausea, and vomiting.

Rare but serious effects include acute kidney damage, muscle breakdown (rhabdomyolysis), and seizures. Chronic heavy use — historically seen with absinthe, an alcoholic drink containing wormwood — has been linked to addiction, hallucinations, tremors, paralysis, epilepsy, and brain damage.

The safety data advises against wormwood during pregnancy because it may stimulate the uterus. There isn't enough safety information to recommend it while breastfeeding — talk with your doctor or pharmacist about whether it's right for you in that situation.

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 anticonvulsants (seizure medications), this is the main thing to discuss with your doctor or pharmacist before using wormwood. The thujone it contains may interfere with how these drugs work.

Does Wormwood by Herb Pharm 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.
Can I use Herb Pharm's Wormwood if I'm pregnant?
No — the safety data advises against it. Wormwood may stimulate the uterus and is considered unsafe during pregnancy. Talk with your doctor or pharmacist about safer options for whatever you're trying to address.
Is it safe while breastfeeding?
There isn't enough safety information to recommend it while breastfeeding. Discuss this with your doctor or pharmacist to figure out what's best for you and your baby.
What are the side effects?
The most common ones from the oil are muscle aches, nausea, and vomiting. Rare but serious side effects include kidney damage, muscle breakdown, and seizures. Long-term heavy use has been historically linked to hallucinations, tremors, paralysis, and brain damage.
Does wormwood actually work for digestive issues?
We don't have reliable evidence yet to say whether it works for indigestion or other digestive conditions. The studies so far aren't strong enough to draw a conclusion.
Why does this product say to use it short-term?
Wormwood contains thujone, a neurotoxin. Short-term use of properly prepared products may be acceptable, but longer-term or higher-dose use can be toxic. Stick to short-term use and follow the label closely.
What's in the liquid besides wormwood?
The extract is suspended in cane alcohol, which is the carrier. There are no other active ingredients — just wormwood itself.
