Does anyone know what this book is about? What kind of diet is being advertised on this rather garish web-site? At $19. it's not so expensive but if anyone has read it, please tell us.
Thanks.

Personally, I don't know about this book, but using fresh garlic and Cayenne daily helps me feel safe from colds, etc. Also, something containing Vit C. like grapefruit, oranges, fresh lemons, other fruits, etc. I also usually take one or two Vit C. caps at least every other day.
