I too have had coldsores all my life and am 50 yrs old now. I had a sore in the inside of my nose for 3 days , first I dapped peroxide.3% on the outside and the inside where I felt it sore and there was no change into the 3rd day. On the 3rd day I inhaled 3 or 4 puffs of a mix of half water and half .3% peroxide cheap Wal -Mart kind, from a 2 oz spray bottle that you can buy at Wal Mart for .50 in the toothpaste aisle where they have travel size items, and 2 hours later all the nose pain was GONE and no longer had a sore in my nose , it vanished. I also used Apple cider Vinegar the off brand at Wal- Mart GV . It's such a great value too, only $2.99 and I take the pinch or 1/4th tsp of Baking Soda and 2 TBLS of APPLE CIDER VINEGAR in 4 oz of COLD WATER and it has lowered my heartrate from 117 to 72.This has also lowered my BLOOD PRESSURE from to 112/60 I feel full of energy and I do this before I eat first thing in the morning and last thing at night. I sometimes take it at NOON for a pick me up. I no longer have acid reflux/ GERD. I sleep and breathe better as I have sleep apnea.
