herpes simplex
"The first two or three times I used this medication my lesions were past the "weeping" stage of the virus and on to healing. Subsequent applications of this medication now seem to have no effect.  I've moved on to using Zovirax which seems like it not only halts any progress of the outbreak and my healing times are faster than any other medication I've used. Abreva just seems to not work at all now."
