herpes simplex
"Zovirax is my first choice for treatment of cold sores which I've had since I was a young girl. Using it in conjunction with Abreva helps promote healing from within the sores; and eliminates the crusty/scabbing that comes with cold sores. Abreva is best used at the first sign of any itching (that familiar feeling of onset) apply as directed on the bottle, and your cold sore will be gone without anyone noticing you even have one. I am just getting over one and with Abreva alone it took three days, no scabbing or crusty formation making it unsightly and causing embarrassment."
