About the genus

Vincetoxicum is a genus of plants in the family Apocynaceae. Although the species in Vincetoxicum have sometimes been included in Cynanchum, chemical and molecular evidence shows that Vincetoxicum is more closely related to Tylophora, now included in Vincetoxicum. The generic name means "poison-beater" in Botanical Latin because of the plants' supposed antidotal effects against snakebite.
