Cough and sore throat

Good Evidence

ESCOP monograph supports traditional use; trial-grade evidence is modest but consistent with mucilage demulcent mechanism.

How it works

Plantago lanceolata leaves contain mucilage, iridoid glycosides (aucubin, catalpol), and phenylethanoids that contribute to soothing (demulcent) and mild expectorant effects in the upper respiratory tract. Aucubin has antimicrobial activity in lab studies. ESCOP monographs recognize Plantago lanceolata for respiratory and oral mucosal use.
