Many people use lemon when suffering from a sore throat. This is the incorrect thing to do-in fact-it may make your throat worse!
Lemon is in fact alkaline and further irrritates an already sore or inflamed throat.
Also, some people have a sensitivity to citrus which includes lemon.
Best bets when your throat is sore or hurting?
1. Rest your voice. No talking or whispering.
2. Drink lots of room temperature pure filtered water.
3. Warm (not too hot) black tea with a little bit of honey.
