Sweet Wormwood
Artemisia annua
Sweet wormwood has a long history in Chinese herbal medicine, where it is known as qinghao and was recorded in fever remedies dating back over a thousand years, including the writings of the fourth-century physician Ge Hong. Growers and herbalists have also valued its feathery, intensely aromatic foliage, using cut stems as a natural moth and insect deterrent in closets and gardens. Its modern fame rests on a single compound, artemisinin, drawn from this plant and developed into the antimalarial medicines that have since saved millions of lives worldwide, a discovery honored with the 2015 Nobel Prize.

Traditional preparations.
In traditional Chinese herbal practice, a light infusion of the dried leaf was used as a cooling drink during feverish spells. This is a mild, historical preparation, not a treatment for malaria or any serious illness.
Traditionally, a tea is made by steeping 1/2 teaspoon of the dried leaf in 250 ml of just-boiled water, covered, for 5 to 10 minutes, then strained. Used occasionally rather than daily.
Safety.
Sweet wormwood should be avoided during pregnancy and breastfeeding, and it can interact with blood thinners and other liver-metabolized medications. This plant is the source of pharmaceutical artemisinin, but homemade preparations are not a substitute for medically supervised malaria treatment. Those with ragweed or daisy family allergies should also be cautious.
