The yellow oleander is an American plant native to tropical regions. It is grown on an industrial scale for its seeds, of which an oil is extracted and used in the manufacture of soaps. The bark has medicinal properties and natives consider its fruit poisonous; so in Florida is called with the name of another inedible plant, Mexican oleander, although in reality its leaves are narrower. The thevetia name is dedicated to the sixteenth-century French monk Andrew Thevet, extraordinary traveler who is credited with the discovery of a plant that would change the universal history of drugs and leisure, tobacco. However, while Thevet was traveling the Americas, in Sevilla the physician Nicolas Monardes (1508-1577) took advantage of the very condition of the city as a port and stop to America, to acquire and acclimate in his garden seeds and seedlings of species of the New World in order to be able to use them in his medical treatments. Including tobacco, from which he analyzed its narcotic effects it has on those who smoke it as a hobby or to get drunk. Monardes, along with Thevet, was one of the introducers of tobacco consumption in Europe. Two hundred years after the death Monardes, the first tobacco factory in Europe was built in Seville, near the Alcázar, with which it shared the water from the pipes of Carmona, today it is the main building of the University of Seville.
