Chia seed comes from the plant known by the Latin botanical name of Salvia hispanica. Salvia hispanica is an annual herb that is native to Mexico, but chia herb is also grown commercially in South America as well as Australia. Chia belongs to the botanical family Labiatae or Lamiaceae, which is the mint family, and is one of the few members of that family where the seeds are the primary part of interest of the plant. Chia seed is used as food and contains Omega-3 fatty acid, and thus has garnered interest for its health benefits. You may buy chia seed from quality online bulk herb processors.

Chia seeds are also used in the interesting porous clay figures known as Chia Pets. The chia seeds are moistened and then placed on the clay figure, where the chia seeds sprout.

The chia seed is made up of approximately one-third protein, a third oil and a third soluble dietary fiber. The oil in the seed from Salvia hispanica contains two-thirds concentration of omega-3 fatty acid. The seed also contains antioxidants and amino acids. A team of Canadian doctors determined that less than a half-cup of chia approximately contains a similar amount of omega-3 oils as does a pound and a half of salmon, as much calcium as would be found in three cups of milk, and as much iron as would be available in five cups of raw spinach. Chia is also gluten free.

Chia seed can be eaten either raw or cooked. It can be taken as a supplement to add fiber and omega-3 to the diet. Ground seed is used to make a pudding or porridge, and can also be added to breads or biscuits. The seeds can be added to water or juice for a gelatinous and nutritional boost. The seeds can also be sprouted and used as an addition to sandwiches and salads.

Chia has been around for many thousands of years. The Aztecs made wide use of Salvia hispanica in their culture. The name of the seed actually comes from the Aztec word "chian," which is Aztec for "oily." The Aztecs ate the seeds of Chia as one of their primary food sources. When the Aztec priests demanded taxes and tribute to be paid, people were expected to bring the seed of chia plants as payment.

Although there is a similar plant that goes by the name of Golden Chia, that plant is not grown widely for commercial harvest. Look for a quality online dried herb provider that directly sources their chia from suppliers when you decide to buy chia seed.
