Horehound

Marrubium vulgare
herbcoughexpectorantbitterdigestionsyrup

Horehound is a classic bitter herb used for cough support, especially when mucus is involved. It’s famously used in horehound candy and syrups because the bitter compounds can help support a more productive cough and soothe the throat when paired with honey. It also has a secondary role as a digestive bitter.
