cold sores
"I've been using this for cold sore outbreaks for about 5 years now.   When I feel a cold sore appearing (hopefully before it actually surfaces), I take the standard 2g immediately and 2g 12 hours later.  So far, it has worked like magic every time.  If I catch it early enough, I see the effect shortly after the second dose.  I'll have some swelling and redness, but within a day it kind of shrinks back into my skin and gradually disappears.  However, if blisters already appeared and the damage to the skin has been done, I'll have a scab.  Either way, the cold sore heals much faster and I've had no side effects."
