This is a post in response to a nurse...I suggested that one could use cs in a 
nebulizer..this was her response. Is it unsafe to use silver as an inhalent?
thanks everyone...deb
in itself it is non toxic.  However,  it is an element,  a sort of solid (  
microscopic particles )  and if they get down into the lungs,  can interfere 
with the cellular transfer of oxygen and carbon dioxide.  So,  when inhaling it 
into your nose you have to make certain you do not inhale too large of 
particles of it,  so that it does not go any further back than the back of your 
throat.
