Charles do you have a lab assay of some bentonite. I would be very interested in seeing it.
Also if you have some metabolic research that I'm not aware of concerning caffien stimulation via the hepatic nerve, I would also like to see this documentation.
It seems many ND's have varying views in these regards. I know of a top notch, esteemed American ND who swears by both modalities. Her name is Gloria Gilbere and she has authored three books. ALso Sherry Rogers MD also endorses these techniques.
Could you qualify your staments with more depth please.
