"Don't use tap water to make your colloidal silver. Use pure distilled water only. And don't take very large dosages or strong concentrations for long periods of time"

This quote by Stan Jones is cautioning against the use of faucet water when making colloidal silver. He recommends to utilize only pure water instead. He also cautions versus taking big dosages or strong concentrations of colloidal silver for prolonged amount of times. This is likely due to the capacity for unfavorable side effects, such as argyria, which is a condition that causes the skin to turn a bluish-gray color. It is necessary to keep in mind that colloidal silver is not approved by the FDA for any medical use, and it is not understood to be efficient for any medical condition. Therefore, it is important to consult with a healthcare expert before taking colloidal silver, and to follow their recommendations relating to dosage and period of use.
