El cultivo del ricino y el amba’y en comunidades guaraníes del Nordeste Argentino, aproximación etnobotánica de su historia y cosmología

This work studied the historical evidence of the cultivation of “amba’y”, Cecropia pachystachya (Urticaceae) in domestic areas of Guarani communities and its replacement by the castor bean or “ricino”, Ricinus communis (Euphorbiaceae), whose cultivation is a current practice. Information obtained on uses of castor bean and on the mythical origin of the amba’y is useful to achieve an etymological approximation to the name “amba’y” alternative to those previously proposed by Leon Cadogan
