¼teaspoonCayenne pepperAdd more if you can - as much as you can stand
Brew tea, then mix everything else in. Stir well.
Gargle with small sips of the tea. Get it as far back in your throat as you can and keep gargling as long as you can stand it. Spit it out, and repeat every 15-30 minutes for several hours. You should feel the burn of the cayenne (within reason!).
