Urena is a genus of plants which grow in various tropical and subtropical areas throughout the world. Some view the plant as a weed, but others make use of its fiber for various purposes. Extracts from its leaves or roots have broad spectrum antibacterial qualities. The leaves and flowers are also a famine food in Africa.
Its seeds are spread by animals. Roots and bark are used as cure for hydrophobia. Fibres obtained from it are used for making coffee sacks in Brazil.
