i have never tried it but i have thought about it. it sounds like it would be a great idea. chlorophyll is a superb detoxer and will detox and neutralize pathogens. also there is a direct pathway between the lower bowels and the liver which means that the wheatgrass juice will go directly to the liver which would be a good thing also.
if you try it please post how it goes, i would be interested in hearing about it.
