I keep organic ACV in the fridge and use it all the time but had never tried it on cold sores which I occasionally suffer from. After a really busy period without enough rest I was starting to feel very run down and sure enough the other morning I woke up with one cold sore above my lip, and a separate one just starting nearby. I thought i'd try the ACV - dabbed straight on with a cotton bud. Immediately I could tell it was helping, so I applied it a few more times during the day. The one that had already started dried up to a mild scab and the other one retreated completely without erupting. Glad to see others know about this too, it really works.Replied By Anonymous (Canada) on 12/20/2016
This is probably what I should have done. Instead I held the cotton ball on my lip for 5 minutes or more. My lip swelled and it's still swollen a day later. I'll try this again in the future if I get another sore, but definitely will use it carefully. I used organic apple cider vinegar.
