 The Clinoptilolite is found in numerous parts of the world in different deposits and it's a quartz-like crystal that acts like a molecular sieve to where it has this very porous honeycomb cage structure that is negatively charged. So it acts like a magnet to bind in a positively charged heavy metals and other environmental toxins in the environment. It's the reason that the Romans used it to line the aqueducts so they didn't die of lead poisoning. And when they didn't use it, we got nero and it's the reason that when Chernobyl melted down that they dropped a half million tons of the powder over the meltdown site because of its ability to bind cesium and strontium, they've used it in Three Mile Island, they used it in Hanford, they've used it in Oak Ridge, they used it in Fukushima. So it's very well published, very well proven.
