Short answer: Mullein Leaf Extract is traditionally used to support lung function and soothe the respiratory tract, while Bromelain (Pineapple) is a natural enzyme traditionally used to support respiratory health and help maintain open, clear airways.
Why an enzyme is paired with a traditional botanical
Bromelain's enzymatic action offers a genuinely different mechanism than Mullein's soothing, traditional botanical role — two complementary contributions to the same spray.
Why this pairing forms PureLung's "Clear Airways" pathway
PureLung's Mullein, Bromelain and Ginger are traditionally used to soothe the respiratory tract and help maintain open, clear breathing pathways — one of the kit's three stated mechanisms.
💡 Worth knowing: Bromelain is sourced from pineapple — worth noting for anyone with a pineapple or bromelain-specific sensitivity.
