Hi John,

This is an excerpt from the article:
"Critics of NCD, however, are saying this substance causes cancer. How can that be? They're referring to the fibrous structure of zeolite crystals and the problems encountered when a person inhales tiny crystalline structures. Inhaling asbestos, for example, is known to cause lung cancer. The tiny, knife-edge fibers in asbestos slice up the tissues of your lungs, then embed themselves and interfere with normal lung tissue function, ultimately leading to cancer (20 or 30 years down the road, sometimes).
My first response to the critics is simply that the zeolites in NCD are never inhaled. This is a product that's swallowed, not breathed in. So we're talking apples and oranges here. Of course volcanic rock will cause cancer if you grind it into fine dust and inhale it for hours on end. Almost any crystalline substance would do the same. But consuming it orally is an entirely different story.
We consume many other crystalline structures orally, including minerals and amino acids from our daily diet. Silica, for one, is a common nutritional supplement, and there's no indication that swallowing silica is harmful. Even spinach contains crystalline structures. And zeolites are on the GRAS (Generally Recognized As Safe) list maintained by the FDA. Not that the FDA has any credibility in my view, but it is a GRAS substance.
You can see this GRAS status mentioned at:
http://www.gsaresources.com/PDSZK406H.htm. There, the page goes on to explain, "Natural zeolites are inert, non-toxic minerals which are federally classified as GRAS (generally recognized as safe) in most applications and exempted from regulations and reporting when used in accordance with good agricultural practice and when less than 2% in animal feed products (40 CFR, Part 180.1001)."

I would also question the critics of zeolites with an obvious question: if zeolites caused cancer, then how did 78% of the stage 4 cancer patients in the clinical trial find themselves in a state of full remission after taking NCD? Obviously, if the substance promoted cancer, those people should never have survived the study. Seven subjects didn't survive, actually, but they were late-stage cancer patients, and the trial lasted 14 months.
Keep in mind this was a small study, so it doesn't prove anything conclusively all by itself. I've seen some talk on the 'net that claims this substance has been proven to cure all cancers with a 100% cure rate and other similar nonsense. That's extremely irresponsible, given how little we actually know about the efficacy of this supplement in the context of different diseases or conditions. More research clearly needs to be conducted. It may someday be solidly proven that NCD prevents or treats cancers, but the supplement is nowhere near that status today. (It would cost probably half a billion dollars just to fund the studies to determine the answer to those questions, by the way.)
The Scientific Research Monograph by Rik Deitsch explains more about the safety of NCD:
The zeolite particles are negatively charged in the entire pH range (pH 1–11). Electron microscopy shows an absence of fibers, and most particles are round with a very rough surface. The absence of fibrous, positively charged particles is encouraging since such particles are present in asbestos and erionite zeolites, which are highly carcinogenic and mutagenic. In addition, activated zeolite particles do not catalyze the production of hydroxyl radicals, unlike asbestos or erionite. It seems that absence of fibrous particles capable of producing hydroxyl radicals makes this zeolite sample nontoxic and noncarcinogenic, at least when applied orally."
I will let you know in a few weeks when my mother has her blood test.
Thanks for caring,
Joan
