Salt plus Colloidal Silver = silver chloride, which is what the infamous Papa Smurff used to turn himself blue with Argyria.
Yes I'm aware of that. Also I read that he was drinking about 8oz 3 times a day.
Odd that you say Colloidal Silver burns your nose - I have never had colloidal silver burn me either when irritgating my sinuses or using as an eyewash.
Alone no burning sensation either place. Only when mixed with water to irrigate the sinuses.
The water irritates the nasal membranes. Not sure what would happen with tap water. I use distilled.
You have been scarce. Couldn't decide if the WM ran you off, or Luella, LOL
