A friend lent it to me-- I put it down after a few chapters because it is so poorly researched and written. It is includes some ancedotal evidence, mostly opinion and an occasional study (no bibliography included). There are several instances when he references a study, but does not cite it so that one can check the facts. That's fishy to me.
Secondly, he makes an effort to appeal to your emotions. Again, fishy. Give me facts. I realize that there have not been many studies on herbs, but there are some he could have used. Or, he should have conducted some himself. Enough with the attempts at manipulation.
The gist of the book is manufactured stuff is bad for you. Lay off things with preservatives, GMO, etc. However, he doesn't offer any real cures in the book, just lays out the problems and side effects of the modern diet.
In his conclusion, he says that for a solution, his readers should go to his new website,
www.naturalcures.com. And there is a membership fee to get the natural cures.
Google him-- it's interesting.
