Iodine Painting: A Natural Remedy for Sore Throat

Iodine to cure sore throat- It didn't work for me! I was so surprised and a little skeptical because so many were saying all you do is rub some iodine on your wrists and neck. I've had a sore throat for 4 days now and I tried it in desperation, but nothing happened. I have a big presentation tomorrow and all I have to show for my herbal remedy to cure my excurciatingly sore throat are yellow neck and wrists! Maybe I did it wrong, but gargling 1 tsp of the Apple Cider Vinegar in a glass of warm water worked better for me!!
