Is Comfrey Safe for Skin?
Safety discussions around comfrey often stem from its content of pyrrolizidine alkaloids (PAs) — compounds that can be harmful if ingested or absorbed in large amounts over time.
Modern regulatory bodies, including the European Medicines Agency (EMA), distinguish clearly between internal use (contraindicated) and controlled topical use.
Key safety considerations include:
-
External use only
-
Avoid application on broken skin
-
Limit duration of use
-
Prefer PA-reduced or filtered preparations
