Elephantopus is a genus of perennial plants in the daisy family.[4][5][6]

The genus is widespread over much of Africa, southern Asia, Australia, and the Americas.[3] Several species are native to the southeastern United States,[7][8] and at least one is native to India and the Himalayas.[9][10][11]

Uses

Elephantopus scaber is a traditional medicine[12] and other species, including E. mollis[13] and E. carolinianus,[14] have also been investigated for medicinal properties. Elephantopus scaber contains elephantopin which is a germacranolide sesquiterpene lactone containing two lactone rings and an epoxide functional group.[15]
