![Asclepias is a genus of herbaceous, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged.[3][4][5] Most species are toxic to humans and many other species, primarily due to the presence of cardenolides, although, as with many such plants, there are species that feed upon them (i.e. leaves) and from them (i.e. nectar). The genus contains over 200 species distributed broadly across Africa, North America, and South America.[6] It previously belonged to the family Asclepiadaceae, which is now classified as the subfamily Asclepiadoideae of the dogbane family, Apocynaceae.](https://media.istockphoto.com/id/1667861664/photo/common-mullein-in-new-england-stone-wall.jpg?b=1&s=612x612&w=0&k=20&c=Q6Dnj_QhVJQH76K3d5YpLVgamUAr71na2GjeX84vBS0=)
