Herbarium of the Ancients — Detailed Monograph

Amaranthus dubius

Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek professional advice before use.

Like many amaranths, the leaves may contain oxalates and nitrates, especially if the plant grows in soils rich in nitrogen fertilizers; proper cooking is traditionally recommended before substantial consumption. People prone to kidney stones or following a low-oxalate diet should consult a healthcare professional before regular consumption. Avoid harvesting near polluted or treated areas, as the plant tends to accumulate nitrates and heavy metals from the soil. For any use other than regular culinary purposes (poultice, prolonged use), consulting a healthcare professional is advised.

Cooked leaves as vegetable

Young leaves are washed then cooked in water for a few minutes, similar to spinach, often accompanied by oil or other vegetables according to local traditions. A handful of fresh leaves per serving, consumed as a meal accompaniment.

Infusion — Dried leaves

Compress — Fresh crushed leaves
