Haven't had a serious sore throat in almost a DECADE now since using, along with hot sauces, Cayene Pepper ...
Seriously, I had roughly one sore (strep) throat a year - and cured that cycle through the use of Cayene Pepper (several taps in coffee usually). I have *never* been so healthy in my life ...
I guess my dad was smarter than I gave him credit for. When I was about 14 (1954) I tried to beg off school because of a cold. He gave me 2 tablespoons of hot sauce & pronounced me cured. I don't think I ever complained about a cold again.
