Affiliate Marketing Secrets

I’ve been doing some looking around on the internet for ways to get rid of Bacterial Vaginosis, and keep stumbling accross this book “3 Days to Permanent BV Relief” or “BVCures”. It seems like the web is flooded with this, has anyone actually tried this book? I’m not willing to pay $50 for a book, sorry. I see that the “remedy” in this book can actually be found elsewhere on the net, if you’re willing to do the research. Any research I do only turns up tons of marketing websites trying to sell this book.
Is there an actual remedy, or are these just charlatans complaining about the dirty little secret health companies won’t tell you, meanwhile they won’t tell you unless you buy their ridiculously overpriced book?
