Mullein tea may possess many benefits. This can potentially include supporting lung health, and having an antimicrobial effect. However, there is limited evidence supporting this and more research is still necessary.
Mullein tea is a beverage that has played a role in traditional medicine for hundreds of years. People have used tea made from the leaves of the common mullein plant (Verbascum thapsus) as a herbal remedy for persistent coughs, asthma, and colds.
Mullein refers to a genus of plants, containing over 2,500 species, native to Europe, Asia, and Africa. V. thapsus is a single species of mullein. People worldwide have tried it for its aromatic flavor and potential medicinal properties.
