cold sores
"Great product.  I've had cold sores since I was a kid (40+ years).  I carry this product with me all the time.    Usually get a cold sore two / three times a year but when I do, I'm ready.  Real important, the moment you feel the tingle apply the med.  Usually heals the sore in 3-4 days, but better than the normal 8-10 days.  Earlier comment stated, do not squeeze the tube, that is correct.  Even a slight squeeze you will waist alot.   I usually store it (tube) in the prescription bottle that it comes in."
