Sweet Annie

Artemisia annua, also known as sweet wormwood, sweet annie, sweet sagewort, annual mugwort or annual wormwood, is a common type of wormwood native to temperate Asia, but naturalized in many countries including scattered parts of North America.

The chemical compound artemisinin, which is isolated from A. annua, is a medication used to treat malaria due to Plasmodium falciparum, the deadliest species of malarial parasite. Discovery of artemisinin and its antimalarial properties made the Chinese scientist Tu Youyou recipient of the 2011 Lasker Prize and 2015 Nobel Prize in Physiology or Medicine.
