Herbarium of the Ancients — Detailed Record

Erythrina vespertilio

Please read before use: the information provided 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 with children, seek advice before use.

Enhanced precautions for this plant: The genus Erythrina is known to contain alkaloids (erythrines) with potentially sedative and neuroactive effects; internal use should only be undertaken under the supervision of a qualified professional. Use is not recommended during pregnancy or breastfeeding due to insufficient safety data. Do not combine with sedatives, anxiolytics, or other central nervous system depressants without medical advice. The traditional uses reported primarily concern Australian Aboriginal communities with detailed and contextual knowledge of the plant; Western scientific documentation remains limited, warranting great caution outside of this framework.

Poultice — Bark

Bark poultice for skin

Fresh bark was pounded and moistened to form a paste, applied directly to the affected skin area. The preparation was traditionally made at the time of use, without prolonged storage. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Decoction — Bark or root

Traditional decoction for external use

A piece of bark or root was boiled in water, then the cooled liquid was used as a wash or compress on joint pain. Internal use exists in some traditions but requires guidance from an experienced practitioner due to the alkaloids present. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Sourcing the plant
