Both the Europeans and the Indians smoked the dried leaves to treat bronchitis. Used as a fish poison. A methanol extract has been used as an insecticide for mosquito larvae. Mullein stalks were traditionally used as a cheap torch.  Mullein is Latin for “soft”.  Was used for lamp wicks before cheap cotton was available.  Mullein oil used to naturally treat dog ear infections.  Quaker women rubbed Mullein leaves on their cheeks to make them pink.  Anyone using Mullein leaves as toilet paper found those cheeks pink as well.
