Salvia hispanica, commonly known as chia, is a species of flowering plant in the mint family, Lamiaceae, native to central and southern Mexico and Guatemala. The 16th-century Codex Mendoza provides evidence that it was cultivated by the Aztec in pre-Columbian times; economic historians have suggested it was as important as maize as a food crop. It is still used in Paraguay, Bolivia, Argentina, Mexico and Guatemala, sometimes with the seeds ground or with whole seeds used for nutritious drinks and as a food source.
