20 Natural Remedies for a Cold Sore
Vanilla Extract
It keeps our baked goods smelling delicious, but did you also know that vanilla extract can also help interrupt the life cycle of a cold sore and keep it from erupting? But there's nothing really magical about the vanilla--it has more to do with the fact that pure vanilla extract is at least 35% alcohol, which can help to kill germs and viruses.
If you think that a cold sore might be coming on, apply pure vanilla extract to the problem area a few times per day. You might just save yourself a little pain and annoyance down the road!
