Identity & origin
BOTANICAL IDENTITY
The right name is the first step.
Ipomoea purpurea 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. Source name: Ipomoea purpurea (L.)Roth.
Also known as: Ipomoea purpurea (L.)Roth, Convolvulus purpureus L., Ipomoea gerrardiana Rendle
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.

Properties & uses.
Historical record: purgative
SEPASAL records an earlier use involving roots under “purgative” (use group 59944). This is a documentary report, not a demonstrated action in humans. The entry does not establish an effective dose, safety or a suitable home preparation. The original publications are cited by Kew; they have not all been consulted directly.
Use reported in a survey or inventory. This establishes neither benefit nor safety.

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
- Toxicity is reported in SEPASAL. No home preparation or ingestion.
- 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 is not a systematic adverse-event review. Toxicity is specifically flagged in the source.
Pregnancy & breastfeeding
Safety during pregnancy and breastfeeding is not established here. No medicinal use is recommended.
Children & adolescents
No paediatric preparation or dose is validated by this notice. Do not extrapolate historical adult uses to children.
If symptoms persist, worsen or are unusual, consult a healthcare professional. In an emergency, contact the emergency services.
