Well i'm a person who gets laryngitis so many times. becuase i talk a WHOLE lot and sing a lot. so i get it a lot. it's usually caused if you have a cold or bad allergies,,and flem goes up and down your throat and that irritates the vocal chords so you loose your voice. my one rememdy is a type of echnichea sold at vitamin places called "Singers saving grace" by herbs etc. the other cure is hot water,,,tablesoon vinegar the juice of half a lemon and plenty of honey all mixed in a tea. both are disguisting tasting but they do wonders for your voice. also try large amounts of HOTT lemonade. hope i helped.
