I bought the DMSO spray to use on my face a few weeks ago. I tried it and it burned like hell so I had to wash it off. I had a genital outbreak about 3 days ago, I spray it on the spot and the bump was gone in about 2 days.
I haven't bought the book. I'm not sure if I want to, but so far the DMSO worked. I also take lysine, vitamin C, zinc and vitamin B. Try it, it might work for you. Valtrex is sooo expensive.
