Artemisia annua(L.) is the plant from which artemisinin (the active
compound in modern anti-malarial drugs) is extracted. It is
commonly known as sweet wormwood, sweet annie or annual
wormwood. Artemisia annuci is known to have originated from China
where it naturally occurs in Chahar and Suiyuan provinces at altitude
1000-1500 masl. Its use as a remedy for malaria- related fevers is
known to date back to 340 AD.
