Short answer: Mullein Leaf Extract is traditionally used to support lung function, soothe the respiratory tract and help maintain clear breathing pathways.
Why Mullein is delivered as a spray specifically
This traditional respiratory botanical is included in PureLung's oral spray format, delivered directly rather than swallowed as a capsule.
Why "traditionally used" is a careful, honest qualifier
This phrasing reflects Mullein's historical reputation without overstating a specific, guaranteed modern clinical mechanism for the finished spray.
💡 Worth knowing: Mullein is one of five botanicals in PureLung, alongside Ginger, Bromelain, Lemon and Cordyceps.
