HelloPharmacist Scorecard of Wormwood by Hawaii 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: certified organic Wormwood extract. Wormwood is a plant extract traditionally used in herbal medicine.

The product also contains vegetable palm glycerin and alcohol 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 on wormwood's effectiveness isn't established in the data we hold. We have insufficient reliable evidence to rate it for biliary disorders, Crohn disease, depression, dyspepsia, or osteoarthritis.

If you're considering it for a specific condition, talk with your doctor about what the research actually shows and whether it's the right choice for you.

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 in higher amounts. Short-term use of properly prepared products may be acceptable, but you'll want to be cautious.

The oil from wormwood leaves can cause muscle aches, nausea, and vomiting. Rare but serious side effects include acute kidney damage, muscle breakdown (rhabdomyolysis), and seizures.

Chronic heavy use has been linked to addiction, hallucinations, tremors, paralysis, 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 either. If you're pregnant or nursing, talk with your doctor or pharmacist before using this product.

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), check with your doctor or pharmacist before using this product—wormwood may interfere with seizure control. No other medication interactions are documented in our data for the ingredient we hold, but that doesn't rule out interactions with your specific prescriptions, so run them through the search tool on this page.

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 a potent herbal extract with serious safety concerns, including neurotoxicity and the risk of organ damage with long-term use. If you take anticonvulsants, you'll need to clear this with your doctor or pharmacist before starting.

Pregnant or breastfeeding? This one's best avoided.

For anyone else, weigh the uncertain benefits against the documented risks with your own healthcare provider.
