Quite a lot of woo (suggesting that you can get a high by feeling the pain of your period without painkillers was an eyebrow raiser) but I was prepared to look past that for what I thought was the genuine science in the book as well. Then I got to to section about "seed cycling" which was presented as a fact but if you do a little research hasn't been proved by any genuine studies. Makes me very suspicious about the rest of the "facts" in there so rather than have to cross check every little claim in the book to see if it's nonsense I'm going to drop it there.
