Having a deep tap root makes Comfrey a little difficult to get established in some soils but once settled it seems to last for years.
Because it contains phosphorus, potassium, calcium and allantoin it is extremely useful as a healing agent speeding up the cell renewal in damaged muscle.
A tea made from the old Comfrey leaves as you clean up around them, is fantastic as a compost accelerator.
A poultice of the leaves is also useful in the healing of cuts and bruises and root tincture added to an ointment base has worked well for us in the treatment of arthritic joints.
