need advise

hello all, a very close friend of my family (he is like a brother) was just diagnosised with stage 4 colon cancer and moved to his lymphnodes and some spots on liver.  he is now just beginning an agressive form of chemo therapy.  i am doing alot of research on line to help gather information to contribute in saving my dear friends life.   THE WORLD IS A BETTER PLACE WITH GONZO IN IT!!!... anyways, i was wondering if anyone can be totally honest with me about this mineral i have just learned about called "zeolite". i have seen NO clinical studies BUT  i read so much positive articles and blogs on zeolite ....then i come to a few negative articles and bam ...knocks my high cloud of hope ...
