Nux Vomica is a member of a widespread and diversified tropical and sub-tropical genus which is characterized by the poisonous alkaloid content of the fruits and seeds. Although it grows wild, it is also cultivated for commercial purposes.
The seeds were first brought to Europe in the 15th century, likely as a poison for game and rodents.
In 1640, the seeds were first used in European medicine as a stimulant.
Related species are equally as potent and have long been used as arrow poisons, including S. malaccensis, from southeast Asia.
