Re: Brands and Types of CS

It's probably OK, but with homemade ionic/colloieal silver solutions being so easy and inexpensive to make, why not just make up a fresh batch?  It is very, very hard to turn blue from CS.  Basically you have to make it wrong, such as contaminating it with salt, and drink huge amounts for a long time.

I am not a fan of GSE, especially after seeing studies which found that it was the preservatives used in some GSE products which had the anti-pathogen effect and not the actual GSE.  When it comes to pathogen killers, after colloidal silver I much prefer oil of oregano.
