Identity & origin
BOTANICAL IDENTITY
The right name is the first step.
Amaranthus thunbergii is documented in Kew’s SEPASAL inventory. This notice identifies the taxon and a selection of attributed historical uses. It does not recommend medicinal use.
Also known as: Amaranthus thunbergii Moq., Amaranthus graecizans Baker & C.B.Clarke
The accepted name is reconciled with GBIF; historical source names remain visible as synonyms. Other species and plant parts are not interchangeable. A photograph cannot confirm an identification for consumption.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.

Precautions before use
BEFORE ANY USE
Precautions & contraindications.
This guidance does not cover every individual situation. Missing information is not a guarantee of safety.
The following warnings do not constitute a complete review of interactions or contraindications. An unstudied combination cannot be considered compatible.
Contraindications & precautions
- Historical record only. Do not prepare or consume this plant based on this notice.
- A complete clinical contraindication assessment is not available in the references used here. Missing information is not evidence of safety.
Medicine interactions
- Interactions have not been systematically assessed in this historical inventory. Compatibility with medicines cannot be established.
“Reported” does not prove causality; “possible” may reflect indirect evidence. “None reported” means none in the cited source, not that all combinations have been studied. Do not stop a prescribed treatment based on this profile.
Adverse effects
- The historical inventory does not provide a complete adverse-event assessment.
Pregnancy & breastfeeding
Safety during pregnancy and breastfeeding is not established here. No medicinal use is recommended.
Children & adolescents
