Virola is a genus of flowering plants in the nutmeg family, Myristicaceae. It includes medium-sized trees native to rainforests of the tropical Americas, ranging from southern Mexico to Bolivia and southern Brazil.[1] Species are known commonly as epená, patricá, or cumala. They have glossy, dark green leaves and clusters of tiny yellow flowers, and may emit a pungent odor.

Traditional use

[edit]

Several species of this genus have been used to create hallucinogenic snuff powders.[2]

Chemical constituents

[edit]

The tops of Virola oleifera have been shown to produce lignan-7-ols and verrucosin that have antifungal action regarding Cladosporium sphaerospermum in doses as low as 25 micrograms. Lignan-7-ols oleiferin-B and oleiferin-G worked for Cladosporium cladosporioides starting as low as 10 micrograms.[3]
