The cassava, manioc, casava, or yucca (Manihot esculenta) is a woody shrub of the Euphorbiaceae (spurge family) native to South America that is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. Indeed, cassava is the third largest source of carbohydrates for human food in the world, with Africa its largest center of production.
