PropoMucil® lozenges contain purified propolis, zinc, vitamin C and natural N-acetylcysteine. Propolis has a strong effect against viruses, bacteria and fungi. NAC reduces the formation of bacterial biofilm, which allows propolis to act antimicrobially, while zinc and vitamin C additionally strengthen immunity. Together they clean and strengthen the defense power of the mucous membrane of the mouth and throat. PropoMucil® lozenges act on the cause of inflammation and pain.
