mystery substance helps quite a bit [SEP] i have no idea what this stuff is or how it works but it helps my mouth when it is irritated or when i have a sore in it i had a canker sore which i tend to get when i am sick or stressed and it healed it up before it grew larger as it usually does i burnt my tongue on hot tea last week and swished this around my mouth mixed with water a few times and my tongue was fine the next day it does not heal you up right away but it seems to make you heal faster it burns and tingles too so if you hate that feeling i would avoid it
