Herbarium of the Ancients — Detailed Monograph

Arum cylindraceum

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: The entire plant, particularly the red berries and fresh tuber, is toxic and contains calcium oxalate crystals that cause severe irritation of the oral and digestive mucosa. Never consume this plant in any form without appropriate processing performed by a qualified professional, as homemade preparations carry a serious risk of poisoning. Keep strictly out of reach of children, as the attractive berries are a classic cause of accidental poisoning. Confusion with other Araceae or with edible young shoots is common and dangerous; in case of doubt, consult a poison control center or healthcare professional.

Poultice (historical external use only) — Fresh tuber

Traditional external preparation, for historical purposes only

In certain ancient folk traditions, the fresh tuber was grated and applied as a poultice to healthy skin, never to an open wound. This practice is not recommended today without professional supervision, due to the strong irritant properties of the sap. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
