Analivegam – Alstonia venenata – A Potential Remedy for Snake Bite

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.

Note: Some readers have mentioned that the photos given here are of Theeppala instead of Analivegam. Some have also mentioned that Analivegam is not Alstonia venenata. There is another tree called Analivenga, whose scientific name is Pittosporum neelgherrense. The similar-sounding names in Malayalam can be confusing.

As far as I could find out, the photos in this post are of Alstonia venenata, although I couldn’t confirm it.

Potential Medicinal Values

So far, certain tribals in India have been using the various parts of this tree for therapeutic purposes as well as against snake bites.

However, in ancient literature, there seem to be no prominent mentions of Alstonia venenata. So, even though some sources refer to its use as an anti-venom due to the presence of an alkaloid called indole, it may not be common in the current system of medicines. A study about the phytochemical properties of A.venenata detected the presence of terpenoids as well as various other compounds.

If proper studies or research are done, this plant could turn out to be another valuable addition to the herbal treasure of the Western Ghats. It can be the remedy for snake bites and certain skin diseases.
