Acyclovir
"I started using acyclovir, 2 months ago. I had 9 separate mouth and tongue ulcers, and anal herpes at that time. Presently, I have no anal issues. But, I have two ulcers that just won't go away completely. What I believe to be hsv2 colitis, that was diagnosed as plain ulcerative colitis has improved, after having an acute flare up that has lasted several months."
