Hagenia abyssinica

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: This plant must be handled with extreme caution: the flowers contain potent active compounds (including kosine) that can cause severe digestive disturbances, nausea, and vomiting in case of overdose. Traditionally not recommended for pregnant or breastfeeding women, nor for young children, due to lack of safety data and the plant's potency. Never use for self-medication as a vermifuge: this historical use absolutely requires supervision by a healthcare professional. Avoid any combination with other treatments without medical advice, as interactions cannot be ruled out.

Infusion — Dried Flowers

Traditional vermifuge infusion

In Ethiopian tradition, dried and powdered flowers were infused in hot water, generally taken on an empty stomach in the morning. This preparation, historically reserved for vermifuge use, requires precise dosing and should only be considered under the supervision of a healthcare professional. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Powder — Dried Flowers

Traditional powder

The flowers were also ground into fine powder then mixed with water or honey before ingestion, according to Ethiopian folk practices. Due to the potency of the active principles, medical advice is essential before any use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
