I don't actually see where Waiora claims that their "Natural Cellular Defense" product can be used to treat cancer. In fact, their website states, "These products are not intended to diagnose, treat, cure or prevent any disease." However, what they do claim sounds rather dubious to me:
Waiora’s Natural Cellular Defense has been clinically formulated to help support a healthy immune system, remove heavy metals and toxins, and balance your body’s pH levels.
Natural Cellular Defense is 100% natural and non-toxic and is derived from zeolites. For centuries, the powdered forms of specific zeolites have been used as traditional remedies throughout Asia to promote overall health and well being. The story of these “volcanic rocks” has been passed down from generation-to-generation as more and more people have experienced its life-changing benefits.
Zeolites are natural volcanic minerals with an unique, complex crystalline structure. It’s honeycomb framework of cavities and channels (like cages) works at the cellular level attracting heavy metals and harmful toxins. In fact, because it is one of the few negatively charged minerals in nature, zeolites act as magnets drawing toxins to it, capturing them in its cage and removing them from the body.
According to Wikipedia
, zeolites are often used in filtration systems, such as water purification systems. In aquariums they're sometimes used to absorb ammonia and other nitrogenous compounds. They're also the active ingredient in QuikClot, an emergency coagulant.
So maybe Waiora is right that zeolites will attract toxins inside the body. What I would worry about, however, is that they would also remove good minerals from the body. I'm not a doctor, so I'm in no position to pass judgement on the therapeutic value of zeolites. But I would want to see a lot more evidence before I accepted Waiora's claims.
