This lady doctor is really brave to have published this website. There are some youtube clips posted on that site that you can watch from this post (further down).
She does sell a product, but apart from that there are a LOT of good points and truth in what she says. She basically talks about how parasites wrec havoc in our bodies and then she mentions the importance of clean and functioning bowels.
Enjoy (?) watching those youtube clips from that website (below). They can be somewhat gross and horrid. I wanted to run, run and run!
