Artemisinin, derived from a Chinese herbal remedy, is a potent peroxid
e-containing antimalarial. New types of peroxides, derived from this s
tructure, as well as other naturally occurring antimalarial peroxides,

s. Studies on the activities, modes of action, and toxicities of these
compounds are discussed here by Steven Meshnick and colleagues.
