Plant Monograph: Amaranth

Name of plant:
Amaranth

Catch phrase (Carmina Gadelica or traditional invocation if available):
No Carmina Gadelica reference exists (non-native to Celtic tradition).
In Indigenous American traditions it is often associated with ideas of endurance and sustenance:
“The grain that does not bow to hunger or frost.”

Family:
Amaranthaceae

Genus and species:
Amaranthus spp. (commonly Amaranthus caudatus, A. cruentus, A. hypochondriacus)

Other names:
Love-lies-bleeding (ornamental species), Red amaranth, Pigweed (wild relatives), Kiwicha (Andean grain variety)

Brief introduction:
Amaranth is a genus of hardy annual plants cultivated both as a leafy vegetable and as a highly nutritious pseudocereal grain. Native to the Americas, it was a staple food crop in pre-Columbian civilizations and remains an important food source globally. It is valued for its resilience, nutritional density, and adaptability to diverse growing conditions.

Traditional uses:

• Leaf vegetable used in soups and stews

• Grain used as staple food and porridge base

• Traditional nourishment for strength and endurance

• Used in ceremonial foods in Indigenous Mesoamerican cultures

• Folk use as a “blood-strengthening” nutritive food

Historical use:

• Domesticated in Central and South America over 6,000 years ago

• Major staple crop of the Aztec, Maya, and Inca civilizations

• Used in ritual offerings and ceremonial cakes in pre-Columbian cultures

• Suppressed during Spanish colonial period due to association with indigenous religious practices

• Rediscovered in modern agriculture as a “lost crop” with high nutritional value

Parts used and method of use:

• Leaves (cooked as greens)

• Seeds (cooked whole, ground into flour, or popped like grain)

• Sprouts (culinary use)

• Occasionally stems (young plants, cooked)

Use in healing (modern herbal practice):

• Nutritive food supporting general health and recovery

• High-protein grain alternative in plant-based diets

• Leafy green source of iron, calcium, and micronutrients

• Supports digestive health due to fiber content

• Considered a “functional food” rather than a medicinal herb in strict clinical herbalism

Pharmacology and biochemistry:

• High in complete plant protein (contains all essential amino acids, including lysine)

• Contains squalene (antioxidant lipid compound)

• Rich in fiber, iron, magnesium, calcium, and manganese

• Contains polyphenols and flavonoids with antioxidant activity

• Leaf forms contain nitrates and oxalates (relevant to dietary considerations)

• Observed effects:

  • Antioxidant activity

  • Lipid metabolism support (dietary context)

  • Glycemic modulation via fiber content

Common dosage:

• Seeds: 50–100 g cooked per serving as food

• Leaves: 1–2 cups cooked greens per serving

• Flour: used as partial replacement in baking (often 10–25% blend with other flours)

• No standardized medicinal dosing (food-based use only)

Safety factors (including side effects):

• Generally very safe as food

• High oxalate content in leaves may be relevant for individuals prone to kidney stones (when consumed in excess)

• Excessive raw leaf consumption not recommended; cooking reduces antinutrients

• Rare allergic reactions possible

• Seeds are well tolerated in most populations

First aid / adverse reaction response:

• Mild digestive upset: reduce intake and ensure proper cooking

• Suspected oxalate sensitivity: discontinue leafy greens and seek dietary guidance

• Allergic reaction (rare): discontinue use and seek medical advice if severe

Drug interactions:

• High fiber content may affect absorption of some oral medications if taken simultaneously (separate dosing if needed)

• Theoretical interaction with anticoagulants is minimal but dietary consistency is advised

• No well-documented clinically significant drug interactions at food levels

Horticultural requirements:

• USDA / Canadian zone: 2–11 (varies by species; very adaptable annual)

• Soil pH: 6.0–7.5 (tolerates a wide range, prefers well-drained soil)

• Light requirements: Full sun

• Moisture: Moderate; drought-tolerant once established

• Other notes (growth habit, harvest timing, etc.):

  • Fast-growing annual (60–200 cm depending on species)

  • Produces dense seed heads (grain types) or ornamental tassels

  • Harvest leaves young for best tenderness

  • Grain harvested when seed heads dry and seeds easily shake free

  • Highly adaptable and resilient in poor soils

Sampling of clinical reports / studies:

• Numerous nutritional studies confirm high protein quality and amino acid completeness relative to most grains

• Research highlights antioxidant activity linked to polyphenols and squalene content

• Dietary studies support amaranth as a beneficial component in gluten-free and plant-based diets

• Agronomic research identifies amaranth as a climate-resilient crop with high food security potential

• Clinical literature primarily focuses on nutritional rather than medicinal effects, classifying it as a functional food crop rather than a therapeutic herb
