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: All parts of the fresh plant contain protoanemonin, an irritant and potentially toxic compound through contact or ingestion. Internal use strongly discouraged without supervision by a qualified professional. Never apply to broken skin or mucous membranes; a prior skin patch test is recommended for any external use. Keep this plant out of reach of children and strictly avoid during pregnancy or breastfeeding.

Compress — Leaves

Compress of bruised leaves

Fresh leaves were lightly bruised and then briefly applied as a compress to the affected area, according to traditional external uses only. This practice requires extreme caution due to the irritant potential of the fresh plant. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Decoction — Root

Root decoction for external use

Dried root was sometimes prepared as a mild decoction, used exclusively as an external rub and never ingested, according to reported traditional practices. The preparation and its use should be supervised by a healthcare professional trained in traditional plants. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
