Nux

Nux is the Latin word for "nut" and is encountered in scientific nomenclature as a descriptive element in the naming of species or traits related to nuts. The most widely known usage is in the binomial name Strychnos nux-vomica, commonly called the poison nut tree, which is native to tropical regions of Asia. The epithet nux-vomica reflects the plant's toxic seeds.

Strychnos nux-vomica is an evergreen tree that bears orange fruit and contains seeds rich in alkaloids, especially strychnine and brucine. These compounds are highly toxic, capable of causing convulsions and death at sufficient doses. Historically, the plant was used as a stimulant in tiny doses and as a poison; in modern regulation, handling and preparation are tightly controlled, and many uses are prohibited or require licenses. Some traditional medicine systems have used crude extracts or purified alkaloids in very restricted contexts, but contemporary evidence for safety or efficacy is limited.

In popular culture, Nux is the name of a fictional War Boy in the 2015 film Mad Max: Fury Road; the character's arc centers on loyalty and transformation.
