Once while Pam and I were away from home for a few days, we walked into a store that sold natural remedies. They had everything on sale for half off. I had heard and read a bit about colloidal silver, and when I saw some on the shelf, I bought the bottle.
It worked well for me, and so I wondered if there might be information on the internet telling how to make it. Sure enough, I found http://www.silversolutions.com and read their material. I built my own colloidal silver generator and began to use it.
NOTE: http://www.silversolutions.com is now unfortunately defunct, but you might find a copy of their old website at http://wayback.archive.org/web/*/http://silversolutions.com ? - Meanwhile, you can find lots of good information at http://colloidalsilversecrets.blogspot.com/ and at Colloidal Silver How-To
I used to get severe sinus infections about once every couple of years. Dry weather would result in dried and cracking sinus linings that would then become infected, producing great green gobs of mucous, fevers, and much general discomfort. Not being especially fond of doctors, I would try to "tough it out" and get rid of the infection on my own. I tried hot and spiced tea, garlic, and various other home remedies, all to no avail.
Finally in desperation I would walk into a storefront medical clinic and pay a doctor $75 bucks to tell me what I already knew -- that I had a sinus infection! With the doctor's magic writing (a prescription) in hand, I would then go and pay a pharmacist $50 - $100 bucks for some antibiotics.
Now I simply heat some distilled water, hook up my silver rods to about 30 volts DC, and in 45 minutes I have a very effective antibiotic.
Colloidal silver is perfectly safe to use internally in moderation. The CRC Handbook lists elemental silver as "non-toxic". I've been taking it internally for years, and four out of five friends still consider me perfectly normal. :)
My friend Cal, a microbiologist, tested some of the silver I made by applying it to a colony of staph and strep bacteria in a petri dish. He said that wherever the bacteria were in contact with the silver for a minute or more, they died.

Here is a site that I found recently (2012) with some very good and helpful information about colloidal silver. They also offer some parts and accessories that could help you if you choose to construct your own CS generator: Colloidal Silver How-To

Over several years of use, and after reading about this subject more widely, I've developed my own recommendations for a simple apparatus and procedure for making your own colloidal silver.
NOTE: (January 2012) I've learned a few things that supersede the article below - for example, if you add a 4.7K resistor and LED in series with the batteries, you get two things for a very low additional cost; (1) a battery-check indicator (LED must be in the correct polarity, unless you use TWO LEDs back-to-back!) and (2) a simple constant-current source that keeps lowering the voltage applied across the collidal silver solution to keep the current in the low milliamp range (about 1ma to 5ma, depending on source voltage) as the silver dissociates from the rods into solution. You may also want to use a small aquarium pump "bubbler" to agitate the solution while operating. I hope to update the doc below soon with some more of these details! :)
If you follow these simple instructions carefully, you should be able to easily and reliably make a very effective solution at home.
