Lungbane/lungwort, Brian.
I usually use the word pulmonaria (in appropriate form).
However, in popular form I've always called it lungbane, but am going to have to change to lungwort.
In the case of the only three usages I saw on-line of lungbane (for Pulmonaria), the author was me!
Checked the RHS Plant Finder, so it's lungwort.
Suspect you know of the origin of the name in the Doctrine of Signatures.
Didn't know comfrey, but despite the very slight resemblance of the plant in Cinda's picture to Virginia bluebells, knew it was not that.
Looking at pictures of comfrey on-line, agree with the plant being comfrey.
