Analivegam is an indigenous tree found in the deciduous forests of southern India. Its common name in English is Poison Devil Tree. This small tree is believed to have several medicinal values although a solid study is lacking.

Its scientific name is Alstonia venenata. In Malayalam, the word anali refers to Pit Viper – a group of venomous snakes. So this name might have come from it.A study about the phytochemical properties of A.venenata detected the presence of terpenoids as well as various other compounds.
