if ur snot is yellow/green ya might have an infection and need an Rx…if it’s clear then maybe try Zicam or the 'ol standby: NyQuil…another thing that’s kind of an “old world” remedy is drinking warm wine…preferrably red…put like 1/2 cup or so in a sauce pan, add some sugar, and heat it up on da stove til its just boiling…turn off stove (most important part here…lol)…inhale the vapors…pour in a cup and drink away
