It's so sad that this one lady turns gray from taking silver nitrate nose drops for years and years NOT Colloidal Silver and then tells the whole world that Colloidal Silver made her turn gray. This is a lie put out by the big Pharmas and the media to get people to stop taking cs lest they discover how well it really works and how inexpensive and side effect free it really is. Don't be afraid to take cs. You would drown before you took enough cs to make you turn gray. 5-10ppm cs is more pure water than anything else. Take cs , be healed and don't worry about anymore. Other users chime in please.
