I can feel a cold coming on right now, so I am going to start using collodial silver again.
We know for a fact that the body is able to process colloidal silver quite well if it is made correctly and the dosage levels and concentrations are not too high.
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.
The discoloration is very minimal. I have not turned blue. The extent of skin discoloration is not even remotely near what the news media are saying. It is barely noticeable.
