Comon people are not ignorant! Everone know this guy poisned himself with self made chemical colloidal silver soup! He admitted it!!! What dangers? Where are the Blue People? Where are the dead bodies? With almost 100 years of documented use and they can only come up with 3 Questionable Cases of people with Argyria, and a few 50 year old picture of people with argyria?  With the Billions of people that have existed since 1914, when a reported average of 10,000,000 people that use colloidal silver a year and they can only find 3 poorly documented cases of people with Argyria?  LOW Grade and LOW PPM products aka nanoparticle silver, silver nanoparticles, are made with chemicals, they are effective, but take a VERY Long time to achieve results, and counterproductive due to the chemical consumption.  You would have to drink a gallons of 8 - 20 PPM Colloidal Chemicals a day to have some kind of effect., Just as Paul Karason did. Notice how his beard and hair is now gray. Nobody in their right mind would drink horrific nitrates or other chemicals that would cause you to loose your hair or get premature gray much more, turn you blue, except for Paul Karason. He is forever a classic reason and example as to why you should NOT to make your own colloidal silver, and he is also proof that you have to consume gallons of nanoparticle products to have some kind of effect. So, I ask again, where are the dead bodies? Or Where are the blue people, with over 10,000,000 Users of Colloidal Silver you would see blue people on every corner, maybe one out of 10. You would be hearing News Reporters DAILY showing the deaths of blue people, but the TRUTH is you don’t. Because there are NO real dangers. You would have to be allergic to silver and or consume gallons upon gallons of low grade chemical colloidal silver, at time for it to be a real danger. YOU have to remember, silver was heavily used before the 1940’s as an antiviral and antibacterial element by doctors, and published in medicinal books with applications and treatments. Silver was replaced in the 1940’s by more “Patentable” drugs such as penicillin, and others, and was quickly forgotten about. But it has re-emerged as a notable antiviral antibacterial product due to the fact that modern viruses and bacteria have mutated into stronger strains that are no longer affected by the patentable drugs that USED to work. HIGH GRADE REAL Colloidal Silver is non chemically made, has atom size particles and comes in 3000 PPM to 15000 PPM. It is colorless and is resistant to UV Rays, and extreme heat or cold conditions, and it is CONFIDENTANTLY packaged in clear bottles. High Grade Colloidal Silver Atoms are much more effective due to the fact that single colloidal silver atoms, that re 200 to 300 times smaller than nanoparticles, penetrate into the heart of viruses and bacteria much easier than low grade nano silver. If you can picture 3000 to 15000 atoms penetrating a virus or bacteria, you would see total annihilation of the invaders, low grade low ppm colloidal silver nanoparticles would simply bounce off the viruses and possible only bruise the invaders.
