Cayenne Pepper - it works on soft tissues in the throat (at least for me!) ...
I made the discovery while experimenting with Beef Bouillon cubes while my throat was showing slight signs of a problem - I added several taps of Cayenne Pepper to a cup and MAN! Like 'Drano' for the throat!
My doctor had clued me into the possibility of various 'cultures' growing in the relatively 'cool' area of the throat - and I think (based on just under ten years experience now) I've found a way to keep that area 'cleared out' ...
