Mullein grows in every U.S. state and can often be found along roadsides and in fields and meadows. This plant can grow more than 6 feet high, and it’s recognizable by its large, hairy leaves and stalk of yellow flowers. The entire plant is covered in fine, downy hairs, and mullein’s big, soft leaves are a good substitute for toilet paper — in fact, it’s often called “cowboy toilet paper.” Tea made from mullein leaves can be used to treat coughs, sore throats and bronchitis, and a few drops of oil from the plant’s flowers can be used to relieve pain from earaches.
