Lysine
I got the bottle and got the correct spelling - sorry. It is an amino
acid with B-6. 25 years ago, a guy at GNC told me to give to my husband
who got fever blisters.
A couple of months ago on the internet, a guy told me that when his
nerve damage from shingles reactivates, he takes around 3000 to 4000 mgs
a day for a few days and it goes away.
That’s why I am trying it. Beyond that I don’t know much more and yes it
did get rid of the fever blisters as long as he took 1000mg a day. When
he would forget to take the pills, the fever blisters would come back.
