Mullein (Verbascum thapsus). Mullein tea is a traditional treatment for respiratory problems, such as chest colds, bronchitis and asthma. The leaf tea is slightly bitter; the flower tea sweeter. Both leaves and flowers contain mucilage, which is soothing to irritated membranes, and saponins, which make coughs more productive. Research has shown that the herb has strong anti-inflammatory activity, and lab studies suggest that mullein flower infusions have antiviral properties, as well.
