Chicle, the main ingredient in chewing gum, is obtained from trunks of the chicle tree. Chewing gum is a type of confection traditionally made of chicle or synthetic rubber. Modern chewing gum was originally made of chicle, a natural latex. Latex from the chicle and jelutong trees is used in chewing gum. Wrigley's gum was traditionally made out of chicle, which was sourced largely from Latin America. Both chicle and mastic are tree resins. Some produce other desirable materials, for example gutta-percha ("Palaquium gutta") and chicle from "Manilkara" species. This area is noted for its tropical hardwoods and the chicle or gum tree. Both the Aztecs and Maya traditionally chewed chicle. It is wind-resistant and the bark is rich in a white, gummy latex called chicle. The Mexican version was directed by Alejandro "Chicle" and edited by Alejandro Davalos Cantu. Its latex is used industrially for products such as chicle. Wrigley Jr. Company in August 1952 announced that it would no longer purchase Guatemalan chicle. A fully ripened fruit has saggy skin and does not release chicle when picked. In its native range, it has been a source of latex used to adulterate chicle.
