Drinking a half cup of vinegar also kills whatever is living in your throat, and also cures stomach ache. I did it all the time when I was sick.
That's just bound to make you throw up.
Besides the easiest thing to do, without drinking random stuff, is to just stay under your blankets and sweat a lot. Making sure you also stay hydrated if you sweat a lot.
I did that when I had a sore-throat, cleared up within 1 hour.
