Mullein

Mullein is an expectorant, which helps the body expel excess mucus, usually by helping make your coughs more productive, to bring up mucus that may be settling in chest, lungs and throat.

Mullein is a common plant used for centuries in herbal medicine. Though most gardeners consider it a weed, herbalists often use its flowers and leaves to treat respiratory problems, digestive issues, and skin conditions, among other health concerns.1
There are many different species of mullein, but the most common of them is Verbascum thapsus, or the mullein leaf.

Animal and human research suggest that mullein tea works by reducing inflammation, thereby helping relax the muscles in your respiratory tract. The flowers and leaves of the plant are also used to treat other respiratory ailments, such as tuberculosis, bronchitis, tonsillitis, and pneumonia.
