According to D.C. Jarvis, M.D. (author of Folk Medicine) apple cider can not only soothe the worst sour throat but make it go away for good. It really has worked for me even after only a couple doses! He suggests a teaspoon of apple cider vinegar in a glass of water but I used a tablespoon.
Simply gargle with a mouthful of the vinegar water for as long as you can and spit it out. Then drink a mouthful it. Now gargle again and spit it out. then drink another mouthful.
Repeat this once every hour until your soar throat is gone. Dr. Jarvis says it may take up to 24 hours to clear a Strep throat. Sure can't hurt to give it a shot!
