I did a search for "wooly lamb's ear uses" and the first item was
this blog and a list of the medicinal aspects of its use.
This was a good bit from it:
Other Medicinal Uses
Wooly Lamb’s Ear actually has many medicinal uses. You can heat a few bruised leaves in a pot of simmering water, and use the cooled infusion as an eyewash to treat pinkeye and sties.
Drink a tea made from young, dried Wooly Lamb’s Ear leaves to help with fevers, diarrhea, sore mouth and throat, internal bleeding, and weaknesses of the liver and heart.
You can bruise the leaves so that the juices are released, and put them on bee stings or other insect bites to help reduce the swelling. The same effect can be seen when used for treating hemorrhoids, or for postpartum recovery.
And of
course, there is its use as a field expedient toilet paper, much like mullein.
Look forward to seeing what you and others come up with.
