A modern medical star! This Chinese antimalarial herb is our last line of defence in parts of the world where the malaria parasite has become resistant to all other drugs. The compound artemisinin extracted from the leaves has potent antimalarial activity. Has been cultivated China for at least 2000 years, but its development as an antimalarial drug was recent and was honoured with a Nobel Prize in 2015. Its highly aromatic branches are also used in dried floral arrangements and to make scented wreaths.
