Frequently Asked Questions
No. Common wormwood (Artemisia absinthium) is a different, bitter species used historically in absinthe. Sweet wormwood (Artemisia annua) is the source of artemisinin.
Yes, it can be grown in temperate climates as an annual herb, but its medicinal potency varies greatly with growing conditions.
The 'sweet' refers to its aromatic scent, not its taste, which is still quite bitter. It is less intensely bitter than common wormwood.
Self-medication is not advised. While used in traditional preparations, the raw plant material is not standardized for modern therapeutic use and should only be used under professional guidance.
