I ordered the tea here, after asking Andreas about it - I wanted to know if he endorsed it and he said yes, that it was the correct recipe. Like I said, this is only day 3, so I can't really tell one way or the other. I sort of expected to feel a little something going on in my kidneys (I did when I drank plain celery seed tea, but that was something you drank all at once, and this is something you sip all day), but so far, nothing. It tastes pretty bad, though, I have to tell you ;)
I bought the book as an ebook, which is great - you can download it to your computer immediately after buying it, and you can print parts out or just read it online. It's a great buy at 6.95!
