Chia (Salvia hispanica) is a plant of the genus Salvia in the Mint family. It originated in the central Valley of Mexico. It was largely cultivated by the Aztecs in prehispanic times and was one of the five more important food plants in that time. After the arrival of the spaniards, the plant almost became extinct because of cultural and religious reasons.

Chia is grown commercially for its seed, a food that is very rich in omega-3 fatty acids, since it is the vegetable source with the most Omega 3 content, specifically α-linolenic acid or ALA. It also adds antioxidants and a variety of vitamins, minerals and fiber. For all these health related benefits, chia is in the process of application before the EU authorities to be considered as a novel food.
