Herpes Simplex, Suppression
"Lysine is a wonderful amino acid that suppresses cold sores (fever blisters/herpes simplex/HSV-1).  It is also good to take Vitamin C and E with the lysine, but cut down on any supplements and foods high in  L-arginine such as chocolate, peanuts, gelatin, white and whole wheat flour, wheat germ, carob, oats and coconut.  The ratio between lysine and L-arginine plays a role in HSV-1 and HSV-2 as does stress and not getting enough sleep."
