I really didn't change my diet all that much. I try to stay away from "trigger foods" but really love chocolate so I still eat it in small portions. I'm a white female. The book didn't say anything about sex or ethnicity.
I just added oil of oregano, several drops under the tongue several times a day. I even quit for a week and then started back again. It's not only great for HSV but it has also kept me from catching colds and I didn't get the flu this year. I teach 7 year olds so I'm around a lot of germs too. It definately works for me and I don't see why it wouldn't work for anyone else. I had tried EVERYTHING for 2 years without any success until this.
