I also take it for a sore throat or if i feel like i may be coming down with something usually about 2 or 3 times a year. i have learned that it doesn't take much to make it very strong, after taking it a few times it does become easier, but man that stuff is bitter. But it will clear up a sore throat fast.
Yeah K_duce, brave alittle crazy and desperate! More often that not I can't breathe through my nose and it's driving me nuts. I'm to find something that will help besides an ENT doc.
I dig some every year for sore throat and think it works as good if not better than anything.
