Botanical Description

Annual herb (Lamiaceae), 1-1.5 m tall, with square stems. Leaves are opposite, ovate to oblong with a toothed margin. Small purple to white, two-lipped flowers are borne in dense terminal spikes, followed by small oval seeds (grey-brown, mottled, or occasionally white) - the part used.[1]

Height: 1-1.5 m
Habit: Erect annual herb
Leaves: Opposite, ovate to oblong, toothed
Flowers: Small, purple to white, two-lipped, in dense terminal spikes
Stem: Square, erect
Root: Fibrous annual root system
Fruit: Small oval seeds, grey-brown and mottled (or occasionally white)
Flowering Period: Variable, typically late summer in its native range

Habitat & Distribution

Native to central and southern Mexico and Guatemala, historically a staple crop of Aztec and Mayan agriculture; now cultivated commercially in warm subtropical and tropical regions worldwide (notably South America and Australia) as a food crop.[1]

Harvesting

Seed heads are harvested once dry, typically in autumn, and threshed to release the small seeds.[1]

Parts: Seed
Season: Autumn, once seed heads have dried

Key Constituents

Alpha-linolenic acid (omega-3 fatty acid)[1]

The dominant fatty acid of chia oil, one of the richest plant sources of omega-3 known.

Mucilage polysaccharides (seed coat)[2]

Responsible for the seed's characteristic gel-forming property when soaked.

MucilagePolysaccharides
Phenolic antioxidants (chlorogenic acid, caffeic acid, quercetin, kaempferol)[1]

Contribute to the seed's antioxidant activity.

Protein and dietary fibre[2]

Chia is a complete plant protein source and exceptionally high in dietary fibre.

Pharmacological Actions

Anti-inflammatory[2, 9, 10, 12]
Antioxidant[1, 2, 4, 7, 10, 12]
Digestive aid[12]

Traditional Use & History

Chia seed has an ancient Mesoamerican food-medicine tradition as an energy-sustaining staple food for Aztec warriors and runners. Its modern popularity centres on its dense nutrient profile - fibre, omega-3 (alpha-linolenic acid) fatty acids, protein and antioxidants - studied for metabolic, cardiovascular and digestive support.[1]

Preparations

Whole or ground seed (culinary)[1]

Eaten whole, ground, or soaked to form a gel (due to the seed's high mucilage content), stirred into food or drinks.

Dosage

Whole/ground seed[1, 2]

Typical dietary and study amounts range from about 15-25 g (roughly 1-2 tablespoons) of seed daily, usually soaked or ground for better digestibility. Educational reference only, not a prescription; always take with adequate liquid, never dry-swallowed.

Safety, Cautions & Contraindications

Safety note[12, 13, 14]Info

Never swallow a spoon of dry chia seeds and “chase” with water. They can swell fast and (rarely) cause a blockage, especially if someone already has swallowing problems (American College of Gastroenterology, 2014) Blood pressure / diabetes meds: if you’re on medication for blood pressure or blood sugar, chia as a major daily addition may slightly add to the effect for some people-monitor and talk to your clinician (Saadh et al., 2024) (Pam et al., 2024).

Safety note[12, 13, 14, 15]Info

Duke (2002) does not include a dedicated entry for Chia (Salvia hispanica) in the Handbook of Medicinal Herbs, Second Edition.

Harvest Readiness

[11]

Part: seed
Signals: Harvest the seed after flowering, once the flower heads dry, in late summer to autumn.
Basis: traditional
Source Quote: It is in flower from July to August.
Species Confirmed: 1
Notes: PFAF (REF-3330); the seed follows flowering (July-August) and is collected once the flower heads dry (seed maturation depends on a warm enough summer). PFAF gives the flowering stage rather than an explicit seed-harvest sentence. Single lineage -> provisional.
