The drugless answer to cold sores and herpes is a combination of Vitamin C and Lysine. I know people who have used this combination and haven't had so much as a 'paper cut' feeling, much less an outbreak, in years. It's also easier on the liver than pharmaceuticals and strengthens immune function.
People naturally feel better when the colon is kept clean and the diet is seasonal, fresh, organic and full of live enzymes (raw).
