During this time (pre-industrial revolution), cloth was a pretty scarce commodity. A woman (and it was mostly women) could spend weeks, even months making a single piece of clothing. Would you waste such efforts binding up a minor scratch or arterial wound? Heck no! That’s what Lamb’s Ear is for, as any sensible woman from the 1700s would have told you.
Long ago, it was used as a bandage for minor and major wounds. Supposedly, it has some antiseptic properties, but because it is no longer used in it’s original herbal manner, there is no supporting proof of this beyond the fact that other plants in the Stachys family have been proven to have antiseptic properties.
But for the same reasons Lamb’s Ear made a great Band-Aid back in the day, are the same reasons we use it in our garden today. Soft, furry (absorbent) leaves that just make you want to give the whole plant a great big hug.
