Hard to tell if you are really putting Dr. Weil's opinion forward as something you agree with, but, in any event, I would just like to make a few short comments as other posters have already pointed out the limited usefullness of the medical industry's liver tests.
Dr. Weill really does a great disservice to people when he knocks Liver Flushing without any real basis other than that Liver Flushing hasn't been "scientifically proven" to show benefits, whatever that means. just speaking for myself, I credit Liver Flushing with clearing up my candida totally (I can eat anything and do on occaison, and certainly eat grains every day). more than candida, it totally changed my life. it is worth your while to really look at the issue closely and decide for yourself.
