What you may have missed is that maim-stream medicine and all their mouthpieces and minions have been denying that silver has any internal benefits whatsever for years, while those of us who know better have been saying that nano silver in colloidal and ionic solutions is deadly to pathogens of just about every kind. After having everyone from the FDA to the FTC to the EPA condemning silver and threatening silver makers - and parading around Papa Smurf Paul Karason in a coast to coast media circus, now you suddenly you have scientists saying that nano-silver might be the silver bullet for colds and flu. Provided of course that it is delivered in a patentable form where they attach it to bacteria. There is no need to attach silver nano particles to bacteria, that is just the gimmick. It is the silver nano-particles that are deadly and that is the case regardless of how they are delivered.
Normally silver would also be deadly to just about any bacteria, so I find it to be more than a little concerning to find that they are somehow able to attach silver to a bacteria. What if that bacteria were able to pass on it's defense against silver to other forms of bacteria - such as MRSA? Wouldn't that be just like maim-stream science - find a way to use a patented form of silver against viruses while jeopardizing its effectiveness against bacteria? That way maim-stream medicine would have a new patented anti-viral medicine as well as an effecive way to protect all the billions in profits from their patented antibiotics.
