I'm having genital herpes outbreak, usuallly I take acyclovior. But pharm told me it might affect my ulcer. Any home remedies I can do to dry this up?!

Unlikely. In several studies less than one-half of 1% of people taking an Acyclovir salt developed ulcers and all were over 50 years old. If you already have an ulcer this needs evaluation and treatment, possibly after upper GI endoscopy. See a GI doctor and continue acyclovir. No home remedies work.
