I had an unexpected breakout on Thursday morning. I had no Valtrex. I started reading everything I could to figure out how to get rid of this cold soar. I kept reading about lemon balm and lemon juice was mention as well. I purchased a bottle of pure lemon juice and used Q-tips to apply it through out the day and night. It's Saturday and my cold soar is almost completely gone. I can hardly believe it. I have dealt with this for almost 20 years and no product has worked this quickly for me. A bottle of $1.93 lemon juice. Wow. Am amazed.
