What Researchers Say -- Nano Silver
How does Colloidal Silver work
Colloidal Silver has no known negative side effects. It provides the catalyst which disables the enzyme that all one-celled invaders use for their oxygen metabolism.
In effect, Colloidal Silver 'strangles' over 650 disease-creating bacteria, fungi (including yeasts), viruses, and parasites by cutting off their oxygen supply. Because these micro-organisms are suffocated, rather than poisoned, resistant strains fail to develop (the germs cannot mutate and develop), keeping your body protected and healthy throughout the years.
Yet Colloidal Silver is of no harm to human enzymes or any part of the human body chemistry. It kills all disease-causing organisms, in six minutes or less, upon contact. The body does not develop a tolerance to Colloidal Silver and sufficient amounts of this substance in your body is equivalent to a superior second immune system!
Certain bacteria are essential to healthy body function. Several researchers claim Colloidal Silver only attacks the unfriendly pathogens and will not harm the friendly ones, but one must wonder how it can possibly differentiate. The explanation is that the friendly bacteria are aerobic, while unfriendly bacteria are anaerobic. Silver does not attack bacteria directly, but rather decomposes certain enzymes the anaerobic bacteria, viruses, yeast, and molds require. The silver acts as a catalyst and is not consumed in the process. It is probable that this indirect action is also the reason bacteria cannot develop a resistance to silver, as they do to antibiotics.
