In the 90’s I made & used colloidal silver & the results were good. A friend had an imbalance in his ears that would make him so dizzy, he couldn’t stand or walk around without feeling nauseous. He made & used the colloidal silver & it was the only thing that helped him. By making it yourself, you really don’t know how to determine the strength of your batch & I believe that can differ from batch to batch.. It is very cheap to make though.
While I believe it is very helpful, it is still a considered a metal. Around 2003 or 2004, I did a 21 day fast & for the first four to six days there was the worst metallic taste in my mouth. My body was getting rid of all the silver that I had ingested & the taste was terrible. Safe, maybe for short times, but not for constant use. I also wonder about what it does to ones stomach, I have had leaky gut syndrome & stomach issues quite a bit. I thank the Lord for healing me.
Although acetone occurs naturally in the environment in plants, trees, volcanic gases, forest fires, and as a product of the breakdown of body fat,  the majority of the acetone released into the environment is of industrial origin. Acetone evaporates rapidly, even from water and soil. Once in the atmosphere, it has a 22-day half-life and is degraded by UV light via photolysis (primarily into methane and ethane .  ) Consumption by microorganisms contributes to the dissipation of acetone in soil, animals, or waterways.  The LD 50 of acetone for fish is g/L of water (or about 1%) over 96 hours, and its environmental half-life in water is about 1 to 10 days. Acetone may pose a significant risk of oxygen depletion in aquatic systems due to the microbial consumption.
