I got this from my high school advisor, or all people. It works like a charm and tastes great, too.
In one cup of hot water, mix about a quarter teaspoon of ginger, a pinch of cinnamon, a pinch of sugar and honey to taste. The ginger is healing and will stimulate the cells in your throat to heal; the honey is soothing; the cinnamon and sugar are just for a little extra kick. Enjoy.
