Salvia! It's a herb that works wonders with sore
throats. I boil some, and gargle
when its lukewarm.
I'm quoting this from some random web page I found. Hope you feel better soon!
"It was used by herbalists externally to treat sprains, swelling, ulcers, and bleeding. Internally, a tea made from sage leaves has had a long history of use to treat sore throats and coughs; often by gargling.
