One more attempt to create a reasonable summary of colloidal silver ...

"Many companies sell colloidal silver generators and dozens of web sites provide information for experimenters and home hobbyists. All the machines sold for making colloidal silver use an electrolysis process and make ionic silver. There are no machines sold that are capable of making true colloidal silver."
"True silver colloids are products that do not contain any protein or other additives and whose silver content is predominantly in the form of nanometer-sized silver particles ... In true colloidal silver, the majority of the silver content is in the form of silver particles. True colloids will typically contain more than 50% particles (often 50 – 80%), while the balance (20% to 49%) will be silver ions. When referring to colloidal silver, the word colloid means silver particles. The two critical factors to look for in determining true colloids are the percentage of silver particles and the particle surface area."
"Upon ingestion, the ionic silver present in most colloidal silver solutions will immediately come into contact with the hydrochloric (HCl) acid that normally exists in the stomach to digest food. The chloride ion from the hydrochloric acid combines at once with the silver ion to form silver chloride, an insoluble silver compound. Since hydrochloric acid does not dissolve metallic silver, the silver particles remain unaffected by the stomach acid. Some of the remaining silver particles, due to their nanometer size will pass easily through the lining of the gastro-intestinal tract and will be absorbed into the bloodstream where they will circulate and come in contact with pathogens which will be killed on contact."
Discussion (IMO):
True colloidal silver kills pathogens (bacteria, etc.), but true colloidal silver must be purchased (cannot be made with simple equipment). However, any pathogen not killed by the available colloidal silver circulating in the blood stream (having been absorbed through the intestinal wall), can often reproduce to a level that existed before the colloidal silver was ingested.
Ultimately (IMO), one's immune system is responsible for the real and lasting health of the body. With the possibility that pathogens might remain after colloidal silver therapy (there are many types of pathogens with varying response to colloidal silver dosage and daily frequency) one's functional immune system is a neccessary backup to silver therapy.
Here's a good discussion of the immune system:

Today's "reasonable summary": True colloidal silver is an expensive "medicine" that may or may not be sufficient for the illness requiring intervention (as perceived by the self-prescribing patient)
. Since silver has low toxicity, typical ingestion is rarely problematic but there's a limit to how much silver the body can tolerate (some silver can accumulate in tissues and organs, depending on type ingested, whether or not attaching to bacteria (then killing bacteria and being eliminated by the body), etc.
Obviously
, man's creator intended that immune systems perform the role of disease prevention and recovery (colloidal silver as "medicine" did not exist until the 20th century). That which can be done to improve or heal one's immune system is the better focus for self-prescribed therapy.
