Sweet Wormwood vs Wormwood: Artemisia annua and Artemisia absinthium Explained (2026 Guide)
Two plants, two names, one letter apart
If you have looked at herbal supplements for any length of time you will have seen both of these on labels, often in the same shop:
- Wormwood — Artemisia absinthium
- Sweet wormwood — Artemisia annua
They share a genus. They are not the same plant, they do not contain the same compounds, and they are not interchangeable. People buy the wrong one regularly, because the common names differ by a single word and the botanical names differ by a few letters.
This is a short guide to telling them apart on a label.
Common wormwood (Artemisia absinthium)
A perennial shrub native to Europe, North Africa and Asia, with silvery-grey, deeply divided leaves and a strong bitter aroma.
It is best known historically as the botanical used in absinthe, and its characteristic compound is thujone. Thujone content is the reason wormwood is regulated as a food and beverage ingredient in many countries, including Australia, with limits on how much may be present.
Where you will see it: most commonly in combination formulas alongside black walnut hull and clove. That three-herb pairing has a long history in traditional Western herbalism and is why the three are so often sold together.
Taste: intensely bitter. The name "absinthium" shares a root with the Greek word for undrinkable.
Sweet wormwood (Artemisia annua)
An annual herb native to temperate Asia, now grown worldwide. Feathery, fern-like leaves and a markedly sweeter, more camphor-like aroma than its bitter cousin — which is where the common name comes from.
Also known as sweet annie or qinghao, its traditional Chinese name.
Its characteristic compound is artemisinin, which is a different molecule entirely from thujone.
An important regulatory note: isolated artemisinin and its derivatives are prescription-only medicines in Australia. Whole-herb Artemisia annua preparations sold as supplements are a different thing from isolated artemisinin, but the association is worth understanding if you are comparing products.
Where you will see it: usually as a single-ingredient liquid extract or capsule, rather than in combination blends.

| Other names | Absinthe wormwood, green ginger | Sweet annie, qinghao |
| Plant type | Perennial shrub | Annual herb |
| Leaf | Silvery-grey, divided | Green, feathery, fern-like |
| Aroma | Sharply bitter | Sweet, camphor-like |
| Key compound | Thujone | Artemisinin |
| Usually sold as | Part of a blend | Single ingredient |
How to tell which one you are holding
Read the botanical name. It is the only reliable marker. Common names vary between suppliers; the Latin binomial does not.
Look for it in the supplement facts panel, in brackets after the ingredient name. A label that says only "Wormwood" with no botanical name has told you less than it should have — reputable products state the species.
Second check: what is it sold with? If wormwood appears alongside black walnut and clove, it is almost always absinthium. If it is on its own, particularly as a liquid, it is more likely annua.
What else to check on either
- Botanical name — as above, non-negotiable
- Amount per serving — in mg, from the panel
- Plant part — leaf, aerial parts, whole herb; these differ in composition
- Extract ratio — a 10:1 extract is concentrated; dried herb is not. These are not comparable milligram for milligram
- Base — liquid extracts use either alcohol or vegetable glycerin. Glycerin-based products are alcohol free, which matters to some people
- Allergens — combination formulas containing black walnut must declare tree nuts
Who should avoid Artemisia species
Artemisia species are not recommended during pregnancy. This applies to both plants.
They also belong to the Asteraceae (daisy) family, so people with allergies to ragweed, chrysanthemum, marigold or echinacea may be sensitive.
Both are adult products. Speak to your doctor or pharmacist before use if you are taking any medication or managing a medical condition.
