I believe Colloidal Silver works. However I do believe that stupid virus can be killed off if you internally use Olive Leaf Extract. Since HSV is such a stubborn virus you'll probably need to use it for a few months in order to completely heal up. I am currently using Olive leaf extract (15% Oleuropein) and have been symptom free for a month now, and in that time I have also been sick (flu and cold) and have not shown any symptoms. I was diagnosed in November 2012 and then started taking 5-6 grams of this stuff a day. Anyhow I am going to do this for 1-2 more months and then see how my body reacts with out it.
