I have no idea where this plant came from, or what it is. What I do know is its leaves are covered in little hairs, there's little thorns growing all over it, and just by rubbing its leaf it burns you and leaves a red mark as well as blisters. It stung my mother and I would like to know what it is so I can find a remedy.
