Although I do not have Herpes 2 ..i have been getting cold sores for 24 yrs now..since i was 10.. I have tried EVERYTHING to get it to stop...the first day i felt it coming i applied grapefruit seed extract directly to my lip full strength...I never got it...so it will more than likely work for genital herpes...it did give me dry..cracked lips but would much rather have that than a cold sore..hehe...try this ...nothing else has ever worked for me...originally using it for my acne...seems to do really good on that also..
