Artemisinin

Artemisia annua, also known as sweet wormwood, sweet annie, sweet sagewort or annual wormwood, is a common type of wormwood native to temperate Asia, but naturalized throughout the world.

In 1971, scientists demonstrated the plant extracts had antimalarial activity in primate models, and in 1972, the active ingredient, artemisinin (formerly referred to as arteannuin), was isolated and its chemical structure described. Artemisinin may be extracted using a low boiling point solvent, such as diethylether, and is found in the glandular trichomes of the leaves, stems, and inflorescences, and it is concentrated in the upper portions of plant within new growth
