I have found that raw honey patted on a fever blister works just as well, if not better than that tiny little tube of Abreva, which is pretty expensive.
Good raw honey is a helpful item in the family medicine cabinet. Google search for it’s may uses.
But, NEVER give it to infants under 1 year of age!
Good suggestion and I would add, “raw” honey means honey that comes from a local beekeeper and not store bought which means it has been pasteurized which ruins all the “good stuff” in honey.
Moreover, honey will run after it warms to body temperature so you will have to replace it frequently. Best thing would be to put it on in the evening (not out in public) and cover with a small bandage. A bit of a fuss but one you’ll be glad you made, jacquej is right.
Abreva really is expensive but you don’t need very much and it really works for me. If you put it on the when you feel the first tingle it stops it right in its tracks.
Never tried honey. Not sure where to get the “raw” stuff.
