HelloPharmacist Scorecard of Wormwood by Red Moon Herbs

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.
  • “EXTRACT” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

This liquid contains one active ingredient: wormwood flowering top extract made from fresh plant material. The liquid itself is prepared with water and alcohol as inactive carriers.

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: digestive support and bitter tonic.
  • We looked for evidence on: Dyspepsia, Crohn disease, appetite, indigestion, gastrointestinal health.
  • 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.

The evidence for wormwood doesn't establish whether it works for any of the conditions listed — biliary disorders, Crohn disease, depression, dyspepsia (indigestion), and osteoarthritis all show insufficient reliable evidence to rate in our data.

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, and the safety data raises real concerns. Short-term use of properly prepared products may be acceptable, but higher amounts can be toxic.

The most common side effects from the oil are muscle aches, nausea, and vomiting. Rare but serious effects include kidney damage, muscle breakdown, and seizures.

Chronic use — historically tied to absinthe consumption — has been linked to addiction, hallucinations, tremors, paralysis, and brain damage. The safety data advises against use during pregnancy because wormwood may stimulate the uterus.

There isn't enough safety information to know whether it's safe while breastfeeding, so it's best avoided then too.

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 drugs (seizure medications), check with your pharmacist before using this product — wormwood may interfere with how they work. The thujone in wormwood can have seizure-triggering effects.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Wormwood is not well established for the conditions it's marketed for. If you take anticonvulsant medication, don't use this product without talking to your pharmacist or doctor first.

Even if you don't, the thujone content and potential for serious side effects — especially with chronic use — means you should have a conversation before starting.

Wormwood by Red Moon Herbs: Common Questions

Does Wormwood by Red Moon Herbs 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 wormwood safe to use while I'm pregnant?
No. The safety data advises against it because wormwood may stimulate the uterus and is considered unsafe during pregnancy. Talk to your doctor about alternatives.
What are the main side effects I should watch for?
The most common ones from the oil are muscle aches, nausea, and vomiting. In rare cases, serious effects include kidney damage, muscle breakdown, and seizures. Chronic use has historically been linked to hallucinations, tremors, and brain damage.
Does wormwood actually work for digestive problems or arthritis?
The evidence doesn't establish that it works for indigestion, Crohn disease, arthritis, or the other conditions it's used for. Our data shows insufficient reliable evidence to rate any of them.
Why does this product contain alcohol?
Alcohol is used as a carrier to prepare the wormwood extract in liquid form. It's an inactive ingredient — just the medium for delivery.
Is it safe to use long-term?
No. The safety data says short-term use of properly prepared products may be acceptable, but wormwood contains thujone, which can be toxic at higher amounts and with chronic use. Long-term use carries real risks.
