I have been diagnosed with a fungal infection in my lungs, so I have been doing a lot of research on colloidal silver. Some people are concerned about the darkening of the skin when using colloidal silver, but the research I have done indicates that happens primarily when people overdose on it. I was going into an exacerbation with non-stop coughing/mucous and was about to call my doc for prednisone and an antibiotic. I had just received a bottle of colloidal silver and had read that it is effective when used in the nebulizer. That night I put 1 tsp in the nebulizer and the next morning woke up with no coughing, very little mucous and feeling great. It was truly amazing. I have continued using 1 tsp 2x a day in neb and feel great - no prednisone or antibiotic. TheSilverEdge.com has a lot of info on the silver and here are some links for anyone interested.
