Gelsemium is a genus of flowering plants belonging to family Gelsemiaceae. The genus contains three species of shrubs to straggling or twining climbers. Two species are native to North America, and one to China and Southeast Asia.
Carolus Linnaeus first classified G. sempervirens as Bignonia sempervirens in 1753; Antoine Laurent de Jussieu renamed the genus in 1789. Gelsemium is a Latinized form of the Italian word for jasmine, gelsomino. G. elegans is also nicknamed "heartbreak grass".[1]

All three species of this genus are poisonous. In December 2011 Chinese billionaire Long Liyuan was killed when cat-stew that he was eating was allegedly poisoned with Gelsemium elegans.[2]
Gelsemium has been shown to contain methoxyindoles.[3]
Gelsemium was used as an analgesic drug in the 18th century, and was administered until the patient presented with slight ptosis (drooping eyelids).[citation needed]
