Please 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 advice before use.

Enhanced precautions for this plant: Highly toxic plant: the seeds contain powerful cardiotonic glycosides that can cause serious, even fatal, cardiac disturbances, even at low doses. Never use for self-medication; any preparation from this plant falls exclusively under supervised use by a qualified healthcare professional. Contraindicated during pregnancy, breastfeeding, in children, and in cases of pre-existing cardiac disorders or ongoing medication (risk of interaction with cardiac treatments). Handling of seeds and sap must be done with extreme caution, avoiding any contact with mucous membranes or open wounds.

Seed Powder — Seeds

Traditional powder (historical use only)

Dried seeds were ground into fine powder, then mixed with other plant substances for the making of arrow poisons or highly supervised medicinal preparations. This practice, transmitted orally, required precise knowledge of doses, now not reproducible safely outside a specialized traditional framework. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Decoction — Bark and seeds

Ancient cardiotonic decoction

A highly diluted decoction was sometimes prepared by traditional healers from bark or seeds, reserved for occasional and supervised use. This practice cannot be reproduced without strict medical supervision due to the extremely narrow therapeutic margin of the plant. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
