HelloPharmacist Scorecard of Wormwood 450 mg by Nutricost

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

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: sweet wormwood at 450 mg per capsule. Sweet wormwood (also called Sweet Annie) has been used traditionally, particularly for malaria and hay fever symptoms.

The capsule itself is made from vegetable material and contains olive oil as an inactive ingredient.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Sweet Annie's overall clinical evidence instead.

Moderate

Some clinical evidence supports Sweet Annie for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Allergic rhinitis (hay fever) — rated "Possibly Effective" (Natural Medicines).

The evidence for sweet wormwood is mixed. It's rated possibly effective for allergic rhinitis (hay fever).

For nonalcoholic fatty liver disease and osteoarthritis, the evidence isn't established enough in our data to say whether it works. For malaria, similarly, there isn't reliable evidence we can point to.

Because this supplement is generally used short-term and quality varies widely, it shouldn't replace proven treatments for any of these conditions.

The evidence, ingredient by ingredient Sweet Annie

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.

Taken by mouth, sweet wormwood is generally well tolerated. The most common side effect is nausea and vomiting.

Rarely, it may cause liver injury — one case reported hepatitis with elevated liver enzymes after taking the artemisinin component, though symptoms resolved within two weeks of stopping. A mild allergic reaction (rash and cough) has been reported in one person drinking sweet wormwood tea.

Avoid this supplement during pregnancy because of possible harm to a developing baby. There isn't enough safety information to use it while breastfeeding, so skip it then too.

Because of the liver concerns, be cautious if you take other medications or supplements that stress the liver.

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 — Sweet Annie.
  • The most serious interaction on file is rated Moderate.
  • For scale: 890 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.

Before taking this product, double-check with your pharmacist if you take drugs that stress the liver (hepatotoxic drugs), or any medication broken down by the liver enzymes CYP3A4 or CYP2B6. These are Moderate-severity interactions and could change how your drugs work.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Sweet wormwood may help with hay fever symptoms, but the evidence is still developing and it shouldn't replace proven treatments. If you take any medications that affect or are processed by the liver, or anything metabolized by the CYP3A4 or CYP2B6 pathways, check with your pharmacist first — the interaction risk is real.

Avoid it if you're pregnant or breastfeeding.

Cytochrome P450 2B6 (Cyp2B6) Substrates

Sweet Annie may alter plasma levels and clinical effects of drugs metabolized by CYP2B6.
In vitro research shows that the Sweet Annie constituent artemisinin induces CYP2B6, possibly increasing CYP2B6 activity by 1.6-fold. However, Sweet Annie extract seems to inhibit the activity of CYP2B6 in vitro, suggesting that other constituents of Sweet Annie play a role in its effects on the overall activity of this enzyme. More information is needed to determine whether taking Sweet Annie extract affects the metabolism of CYP2B6 substrates.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Sweet Annie may alter plasma levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that the Sweet Annie constituent artemisinin induces CYP3A4, possibly increasing CYP3A4 activity by 1.9-fold. However, Sweet Annie extract seems to inhibit the activity of CYP3A4 in vitro, suggesting that other constituents of Sweet Annie play a role in its effects on the overall activity of this enzyme. More information is needed to determine whether taking Sweet Annie extract affects the metabolism of CYP3A4 substrates.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use might have additive adverse hepatotoxic effects.
There is some concern that Sweet Annie can adversely affect the liver.

Wormwood 450 mg by Nutricost: Common Questions

Does Wormwood 450 mg by Nutricost interact with any medications?
Yes. Based on its ingredients, Wormwood 450 mg has a known interaction with 889 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wormwood 450 mg 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 take this while I'm pregnant?
No — the safety data advises against sweet wormwood during pregnancy because of possible harm to a developing baby. Talk with your doctor if you're thinking about it.
Is it safe to breastfeed while taking this?
There isn't enough safety information to know either way, so it's best to avoid it while breastfeeding. Check with your pharmacist or doctor for personalized advice.
What's the most common side effect?
Nausea and vomiting are the most common side effects. Rare cases of liver injury have been reported, so if you develop belly pain, dark urine, or jaundice, stop and call your doctor.
Does this work for hay fever?
Sweet wormwood is rated possibly effective for allergic rhinitis (hay fever), meaning there's some evidence but it's not rock-solid. It's generally used short-term, and because quality varies, it shouldn't be your only treatment.
Why does this interact with so many medications?
Sweet wormwood contains a compound called artemisinin that can rev up or slow down liver enzymes responsible for breaking down hundreds of different drugs. That's why it's crucial to check your specific medications before starting.
