Here he speaks to the fact that he sells products on his natural medicine website, and explains his motivations. I have followed his email newsletter since 2000. He started it in 1997. I have found that he often breaks news that nobody else will cover. He brings new science to my attention, and elaborates on the possible ramifications of it. He explains the conflicts of interest inherent in our system of corporate medicine. I find that he has no conflict of interest, his mission is clear and he is accomplishing it.
