warm or cold water depending on preference
2-3 tablespoons of honey
Juice from ~1/3 Lemon
I SWEAR by this whenever my throat is bothering me. I was on vacation last month at Disneyland, just getting over a sore throat/cough. One day it was really cold, damp and I was yelling / screaming with my kids on roller coasters. By the evening I couldn't even talk, my voice was shot and on the verge of going for good. That evening I simmered in a hot shower, inhaling the steam and sipped the honey/lemon drink throughout the next morning. By mid-day my throat was completely healed. My parents were SHOCKED.
I had an ex-co worker ~6 months ago who lost his voice completely. He was struggling with it for 2-3 days. I told him about the honey drink and within a day his throat was healed completely and he could talk again.
Give it a shot... it tastes pretty good too. I drink it all the time now, its healthier than sodas and works well in allergy season. If you use locally grown honey, it helps build your allergy immunities too, if you're allergic to pollen.
if that doesn't work I usually use a throat spray, vics or Chloraseptic.
