Comfrey has been used externally for its wound healing capabilities, it has done this very fast – sometimes too fast as skin forms over a wound before it has healed properly. Hence why is best used for shalow wounds.
It is restricted for internal use in Australia.
The lkeaf contains allantoin, rosmarinic acid,and varying degrees of pyrrolizidine alkaloids depending on species and time of harvest. It is the allantoin that has the healing properties.
Comfrey has also guarded against the deformation of scar tissue.
Generally an infusion (strong tea) of fresh or dried leaves is made and either to soak a part such as a sore finger or to dab on a cut with cotton. Crushed foliage can be applied externally, or a raw leaf rubbed on skin lesions such as rashes and sprains. Comfrey should not be applied to deep open wounds or broken skin.
