Has anyone tried diatomaceous earth for cold sores? I use it to get rid of parasites in my body and I believe can cure cancer. I had polyups in my colon which had cancer cells in them but not started growing twice at my testing. I drank diataemeous earth every day and when I went for last two testings I had polyps no cancer cells. it says it can cure viruses. Check it out. There's human grade and pool grade so make sure to get human grade. It's ground up seashell full of minerals and silica. I have taken it for health reasons and it gives energy and makes you feel great. They give it to animals to take parasites out of their bodies. has great benefits. I have taken it for years. I believe it can suppress cold sores and possibly cure the virus.
