HelloPharmacist Scorecard of Sweet Wormwood by Gaia 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 Sep 17, 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: organic sweet Wormwood (Artemisia annua) aerial parts as a liquid extract. The extract is preserved in organic alcohol and water.

Sweet Wormwood has a long history in traditional medicine, particularly for fever and certain parasitic infections. The plant contains artemisinin and other compounds that are the basis for its use.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: digestive support and healthy elimination.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold shows sweet Wormwood is possibly effective for allergic rhinitis (hay fever). For nonalcoholic fatty liver disease, malaria, and osteoarthritis, the evidence isn't established enough to rate it — we simply don't have sufficient data on those uses.

If you're considering this for a specific condition, talk with your doctor or pharmacist about what the research actually supports.

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.

Orally, sweet Wormwood is generally well tolerated. The most common side effects are nausea and vomiting.

Rare but serious is hepatotoxicity (liver damage) — one documented case involved a patient who developed hepatitis after taking artemisinin (a compound in sweet Wormwood) at high doses for 10 days; symptoms resolved within 2 weeks of stopping. A mild allergic reaction (rash and cough) has been reported with sweet Wormwood tea, and some people have felt numbness of the tongue or throat itching when taking it sublingually.

The safety data advises against sweet Wormwood during pregnancy because of possible harm to the developing baby. There isn't enough safety information to use it while breastfeeding — talk with your doctor or pharmacist for personalized advice.

Sweet Wormwood is generally used short-term; quality and dose vary widely, and it should not replace proven treatments.

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 — Sweet Annie.
  • The most serious interaction on file is rated Moderate.
  • For scale: 893 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, check with your doctor or pharmacist if you take hepatotoxic drugs (medications that stress the liver), or any drugs metabolized by the liver enzymes CYP3A4 or CYP2B6 — a category that includes many heart medications, blood pressure drugs, cancer treatments, and immunosuppressants. Sweet Wormwood may make those drugs more or less effective, or add to liver damage risk.

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.

Sweet Wormwood may be worth considering if you're exploring options for hay fever, though the evidence is modest. The biggest caution is its interaction with liver-metabolizing drugs — if you take any prescription medication, especially anything hard on your liver or metabolized by your liver, check with your doctor or pharmacist before starting.

Avoid it in pregnancy, and don't use it to replace proven medical care.

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.

Sweet Wormwood by Gaia Herbs: Common Questions

Does Sweet Wormwood by Gaia Herbs interact with any medications?
Yes. Based on its ingredients, Sweet Wormwood has a known interaction with 892 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sweet 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 take Sweet Wormwood while pregnant or breastfeeding?
No — the safety data advises against it during pregnancy because of possible harm to the developing baby. While breastfeeding, there isn't enough safety information to know either way, so talk with your doctor or pharmacist before taking it.
What are the side effects?
Most commonly, nausea and vomiting. Rarely, it can cause liver damage (hepatotoxicity). A mild allergic reaction with rash and cough has been reported, and some people feel numbness of the tongue or throat itching when taking it under the tongue.
Does sweet Wormwood actually work for hay fever?
The evidence shows it's possibly effective for allergic rhinitis (hay fever), so there's some promise — but it's not a proven treatment. Talk with your doctor about whether it's worth trying for your situation.
Can I use this instead of my other medications?
No — the label cautions that it should not replace proven treatments. It's meant as a complementary option, not a substitute.
Why is this a liquid instead of a capsule?
The product facts don't specify why the form was chosen, but a liquid extract allows you to adjust the dose more easily and is absorbed quickly.
How long can I take this?
Sweet Wormwood is generally used short-term. Quality and dose vary widely between products, so follow the label and talk with your doctor or pharmacist about how long it's safe for you to use it.
