CS>Newbie/Particle Size

[rwtnbch816]

Hi,   
 I’m not very familiar with the use if colloidal silver so I though I'd drop 
in and listen for a while.  I usually use herbal and nutrition therapies.  I 
recentlyheard that the particle size makes a big difference in whether or not 
cs is safe or not.  Is this true?  Thanks,
Becky
