I remember a college friend getting herpes simplex when we were on our third year of college. Our school doctor told her it is because her immunity was so low. She had really bad blisters and sores on her mouth. The best herpes treatment is the one that will boost your immunity. She was recommended to double up on rest and vitamins and take her antibiotics. She was also cautioned that it will recur if her immunity goes down again. She is now cautious with her health now and takes good care of her body.
