I am a little bit late on this, but my favorite sore-throat soother is hot foods. Fresh made Channa-chur ( Spelling? It is that indian snack foods with almonds and dried lentil and crunchy hotness) will sooth. If that cannot be found, try Better-Maid extra hot barbeque potato chips. It is a great counter-irritant. In non-snacky environments, cinnamon altoids will suppress the tickle and urge to cough.
