Symphytum officinale

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: External use only: comfrey contains pyrrolizidine alkaloids that are potentially toxic to the liver if ingested or applied to broken skin over extended periods. Internal use is contraindicated, as is application to non-intact skin, in pregnant or breastfeeding women, and in young children. Never apply to deep open wounds or to a fracture not immobilized by a healthcare professional. Seek the advice of a healthcare professional or qualified herbalist before any use, particularly if undergoing concurrent medication treatment.

Poultice — Fresh leaves

Crushed leaf poultice

Fresh leaves are lightly crushed or steamed briefly, then applied directly to the area to be soothed, held in place with a clean cloth. This poultice was renewed once or twice daily, always on intact skin. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Decoction — Dried root

Decoction for compresses

Dried and crushed root is gently boiled for about ten minutes in water, then filtered. The cooled liquid is used to soak compresses applied locally to healthy skin. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Infused oil — Dried root and leaves

Comfrey oil for external massage

The dried plant is infused for several weeks in vegetable oil, away from light, then filtered. This oil was traditionally used in gentle massage on bruised areas, never on broken skin. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Sourcing the plant

Comfrey can be found growing wild in damp meadows and along ditches in Europe, but is also cultivated in herbalist gardens; its ready-made preparations (oils, ointments) are available at herbalist shops or specialized stores.
