Chia

Parts Usually Used

The seeds are the primary part used medicinally and nutritionally. The seeds are small, oval-shaped, measuring about 2 mm in length, and can range in color from white to gray and black.

Description of Plant(s) and Culture

Chia is an annual herbaceous plant belonging to the Lamiaceae (mint) family that can grow up to 1 meter in height. The leaves are elongated and serrated, arranged opposite to each other on the stem, measuring 3-5 cm wide and 4-8 cm long. The flowers are small (3-4 mm), hermaphroditic, white or purple in color, and arranged in whorls on the stem with the characteristic structure of the mint family.

The plant is sensitive to daylight and produces small seeds that are ready for harvest when the plant reaches maturity. Under suitable agroclimatic conditions, productivity can reach about 600 kg of seeds per acre.

Where Found

Chia is native to Central America, specifically the southwestern areas of Mexico and Guatemala. The natural sites of occurrence include Belize, Guatemala, Honduras, Mexico, Nicaragua, and Panama, typically found in mountainous areas on sandy loam or clay loam soils with good drainage. Currently, chia is widely cultivated in tropical and subtropical climates including South America (Argentina, Bolivia, Brazil, Ecuador, Colombia, Paraguay, and Peru), Central America (Guatemala, Honduras, Nicaragua, and Panama), North America (Mexico, USA), and Australia.

Mexico remains the largest producer and exporter of chia seeds globally.

Medicinal Properties

Chia seeds possess numerous medicinal properties that have been scientifically documented, including anti-inflammatory, antioxidant, cardioprotective, hypotensive, antidiabetic, hypolipemic, neuroprotective, hepatoprotective, and immunostimulatory effects. The seeds demonstrate significant antioxidant activity due to their high content of polyphenolic compounds, including caffeic acid, chlorogenic acid, quercetin, rosmarinic acid, and myricetin.

These compounds help combat free radicals and may reduce the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. Studies have shown that chia seeds may help reduce blood pressure, lower cholesterol levels, improve blood sugar control, support digestive health, aid in weight management, and protect against inflammation. The omega-3 fatty acids in chia seeds contribute to brain function, heart health, and reduction of inflammation throughout the body.

Biochemical Information

Chia seeds contain several important bioactive compounds. The dominant essential fatty acids are α-linolenic acid (ALA), an omega-3 fatty acid accounting for about 60% of the fatty acid content, and linoleic acid (LA), an omega-6 fatty acid accounting for about 20%. 35 provides significant health benefits. The seeds contain all nine essential amino acids, making them a complete protein source.

7 mg/100g), caffeic acid, chlorogenic acid, quercetin, and kaempferol. The seeds also contain significant amounts of tocopherols (vitamin E compounds) that contribute to their antioxidant properties.

Legends, Myths and Stories

Chia seeds have a rich history dating back over 5,000 years, serving as a staple food for ancient Mesoamerican cultures including the Aztecs and Mayans. Historical records indicate that chia was the second main crop after beans in pre-Columbian societies. In Aztec communities, chia was used not only for food but also for cosmetics and religious rituals. The word “chia” comes from the Spanish word “chian,” which means oily, reflecting the seeds’ high oil content.

Ancient warriors and messengers would carry chia seeds on long journeys for sustained energy, earning them the reputation as a superfood of antiquity.
