E.,
Reduce sugar consumption as it impairs immune function by interfering with white blood cell production and depletes the body of important B vitamins. Instead, snack on whole foods such as hardboiled eggs, rice crackers, soft cheeses, fruits, and vegetables. You may want to even ask your OB if you are able to take extra vitamin B-12 or B-6 as they prevent herpes anywhere in your body. To other minerals are selenium and zinc. I do know that they sell these in Health Food Stores. But PLEASE make sure it is OKAY with your doctor first before trying anything new that could harm you or the baby. These are things that I do when I have a cold sore on my face anywhere. Hope this helps! Good Luck
