[YEA] The best remedy I know for sore throat is Drambuie. It's a Scottish liquer made with malt whiskey and spiced honey, and is 40%. Other similarly strong alcohols might help, but I have never tried them. Weak alcoholic drinks do NOT work.
Just one small sip always provides immediate relief for myself and all my family. If the liquid doesn't seem to touch the particular spot in your throat, I like to gargle just a little bit. I know it sounds gross, and please remember this is a liquer, so you only want a sip and not a whole mouthful.
If the sore throat comes back, two or three more sips throughout the day might be necessary. I have never had to use it more often than this.
Of course I don't think I need to mention that this isn't for kids as the taste is very strong and could upset sensitive stomachs.
Also, just a warning, that a 375ml bottle here in Canada will cost you about $25. This bottle will however last you a VERY long time. If you don't want to fork out that much, there are always small sample size bottles available too.
Honestly though, this has worked in my family for the past 20 years at least.
