[OLDN] Nanosilver potential danger

 

 

 

 

Thanks to Doug Fearn of LDA SE Pennsylvania for this item.

This article appeared in Science News. Here are a couple of interesting quotes:"They found that the tinier silver nanoparticles tended to ratchet down the secretion of cytokines such as tumor necrosis factor, also known as TNF, and of various interleukins such as IL-6. This occurred at the parts-per-quadrillion level. Such cytokine suppression, Perkins says, indicates 'your immune system is not operating at peak capacity by any stretch.'The take-home message, Perkins says, would appear to be that silver nanoparticles can materially alter immunity, in some instances 'taking away the ability for your immune system to deal with pathogens.'"

I think that the safety of silver has been well established, including the discovery that some body tissue actually has silver receptors - indicating that silver is a necessary item for optimal health and healing.

The two passages that stood out to me were these:

"The Connecticut researchers then focused on the ability of immune cells to gobble up foreign bodies for disposal. In their tests, the foreign bodies amounted to tiny naked beads — ones lacking any silver coating. Cells encountered the beads alone or after a three-hour exposure to nanosilver."

"It's also possible, Perkins points out, that the effects his team is reporting would be smaller in a person. Remember, to date they've only been witnessed in a test-tube full of white blood cells or other immune cells."

Which indicates that first of all, the test used artificially created beads exposed to non colloidal silver particles for three hours and secondly that the test was conducted on white blood cells and other immune cells in a test tube, and may not apply to colloidal silver nanoparticles in the human body where such particles release ionic silver upon contact with single celled pathogens and are are neither "gobbled up" by white blood cells and other immune cells nor expose healthy cells to damaging amounts of free radicals.

When there is ever a non-aligned study demonstrating danger from colloidal silver to the human body, then I might be concerned. So far, toxicity levels have been established as 20,000 tablespoons of 20 PPM nano-sized silver particles - an amount that is clearly impossible to ingest.
