I have had great success by applying a therapeutic grade of essential oil of Frankencense to the "itchy" area prior to a sore appearing. The sore doesn't even appear for me as long as I catch it soon enough.
Since herpes 2 is a virus, I drink water with a drop of essential oil of Peppermint in it and I also drink warm tea with a drop of Frankencense in it regularly.
It has been months instead of weeks between "flare ups". Of course I also eat well and exercise to releive stress, however, if the "itch" does begin, I don't need to deal with it by using the Frankencense.
I get my oils from www.youngliving.com. It will ask you for the ID# of the person who referred you -- 315504
