Old knitbone.
This is about the herb Comfrey - also known as old knitbone for it's ability to help broken bones heal.
I've been rubbing it in the skin of my fractured ankle twice a day in the hope that it will help my bone heal.
Just lately I've had to stop using it. The skin where I've rubbed the comfrey ointment has gone dead and is peeling off in great big pieces!
OMG - it shouldn't do that should it?
