About Artemisia annua
Plant: Artemisia annua (Sweet Wormwood) — whole herb
The whole-herb form contains the full spectrum of the plant's active compounds working synergistically together, giving it a wider spectrum of antimalarial action than the isolated artemisinin compound alone. Preferred over isolated artemisinin specifically because using the isolated compound on its own carries a higher resistance risk with continued use.
Reference dosing
| Dosing | Buhner's dosing tables give figures for isolated artemisinin capsules rather than for the whole dried herb specifically — a distinct whole-herb dose isn't separated out in the source material. If using a whole-herb Artemisia annua tincture or capsule product, follow label guidance and start low. |
| Capsule dose (mg) | No capsule mg dose is documented in the source material for this herb. |
Not documented as a standard alcohol tincture ratio in the source material — dosed as capsules/extract instead.
Capsule whole-herb extracts vary by manufacturer (a concentrated extract needs less than a plain powder). Treat these figures as a guide only and follow the product label.
These are figures from the sources used on this site. They are not a prescription. Follow the product label and your prescriber.
Safety and cautions
Contraindications: Memorial Sloan Kettering says people with ulcers or other stomach and gut disorders should not take it. Liver inflammation (hepatitis) has been reported with artemisia and artemisinin products, and rare delayed anaemia has been reported with artemisinin drugs. Lab studies show it can speed up the breakdown of some medicines (CYP2B6 and CYP3A4), but the real-world effect is not established. Pregnancy was not addressed in the source: ask a doctor first. Always check with your prescriber or pharmacist, especially if you take blood thinners or other regular medicines.
Herbs can interact with prescription medicines and other supplements. Check with your prescriber or pharmacist first, and do not use herbs in pregnancy or while breastfeeding unless a doctor agrees.
