Herpes Simplex
"I get a cold sore every May and December... Last December I used Abreva
&quot; At the first tingle &quot; and it just never developed and was totally healed in 2 days. 
Now it&#039;s May and I cut this one off at the pass even sooner but the results are totally opposite. It does seen smaller and less painful then if I didn&#039;t use anything but it&#039;s still a full blown cold sore.
The jury is still out on this subject. I really can&#039;t tell with just 2 uses. But the good news is I have the rest of my life to do more research. I&#039;ll update my review next December."
