Sounds like he would rather people not benefit from a good liver flush.
Since he is in a position of some authority on the subject of helping people healthwise, people will actually believe what he is saying is true unless they already know better, as you and I do.
There is a forum on curezone where if you ask a question about whether something is good or bad, the forum owner will about seventy five percent of the time suggest whatever it is to be bad or worthless.
He will rarely say that something is good.
And I know that a lot of it is good, but it appears that this guy would rather not have people benefit from things that are healthy and valuable.
But since he is in a position of authority on these subjects, being a Dr. of Chiropractic, people simply believe what ever he says about something.
