Species

About 67 species, see text.

Virola is a genus of medium-sized trees native to the South American rainforest and closely related to other Myristicaceae, such as nutmeg. 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

Several species of this genus have been used to create hallucinogenic snuff powders.[1]

Chemical constituents

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.[2]
