I believe the prophet Jesus, and that God uses all sorts of folk to speak good! ;)
Hmm.. I have beetroot in my fridge, it's pretty easy to juice! Are the constituents (the makeup of) beetroot and red cabbage similar? I think first of the dark red qualites of both plants when I think of the two, we use them a lot where I live for picked additions to whole-grain open-faced sandwiches.
I'm doing calcium Bentonite internally 2-3x a day for the very reason you list. :)
