Lysine works wonders on cold sores on/in
the mouth. If you are prone to them, take several doses (1000mg) at the onset
for several days and it will significantly reduce the duration of the cold sore.

I take lysine for me! My chiro recommended
it as an immune system booster when I was coming down with a
cold. Dunno if it really helped, but I didn't get the
cold.
