Sinusitis is the reason I discovered colloidal silver over 30 years ago. I had been suffering from sinus infections my entire life. My work involved frequent travel all over the world. Within a few days, I would come down with a sinus infection at each destination. I would seek help from the local medical community, which would result in the injection of the latest antibiotic. That would usually clear it up in a few days. I had a long history of trying to remedy this situation. I had seen many ears, nose, and throat specialists and allergists. I even had an SMR (subcutaneous membrane restructure) operation, but I was still subject to infections. I was then, and I still am, disdainful of “alternative medicine.” I was in Las Vegas on a job and had been unable to work for three days. I had been bedridden with a fever that would break and reappear, drink a lot of water, and “sweat it out.” I was awake in the middle of the night and listening to an all-night radio program that featured guests promoting various “wacko” subjects, from flying saucers to conspiracy theories.
One of these guests was promoting colloidal silver. He sounded more rational than the usual people on this program. I had not been aware that silver had been used extensively as an antimicrobial before introducing antibiotics. The following day I called the local health food store and ordered an 8-ounce bottle of the colloidal silver they recommended. They sent it over by a taxi, and the driver delivered it to my hotel room. It came with a dropper, and I started to flood my sinus cavities with it. Within two hours, all my symptoms disappeared. I was determined to never be without this remedy in the future.
A few months later, I went to the Philippines for what was to be a relatively long-term assignment. I had been using the colloidal silver I bought in Las Vegas, and it was preventing any recurrence of my sinus problems. I was down to my last few ounces, so I called the health food store in Las Vegas and told them I wanted more of the same thing. They said that they had switched to a new, improved version. So I accepted this and ordered. I received a dark, amber-colored substance with a vinegar-like taste and was very different from what I expected. I decided to find out precisely what “colloidal silver” was and how to make it. The process of electrolysis was no mystery to me, and Michael Faraday I regarded as an old friend. On researching the “state-of-the-art” for making this substance, I realized that no electronics expertise had been applied. I bought some pure silver, 999, and proceeded to make my own.
When I started the thread, the intent was to “clean up” the subject of making colloidal silver. There exists a great deal of misinformation about making colloidal silver. Some of this was deliberate, propagated by people who wish to sell you a product. They will claim they are the only ones who know how to make that particular “silver cure-all.” The pharmaceutical industry saw silver as a threat to their bottom line. They couldn’t patent silver. They could not prevent individuals from devising methods to suspend particles of silver in water. The earliest processes were grinding the smallest possible pieces of elemental silver and merely adding them to water. Fifty years ago, you would find bottles of colloidal silver with instructions on the label to “shake the bottle” before using it. Some manufacturers added nitric acid to the solution, producing silver nitrate, a solution that could be easily misused. This effect was made famous by Rosemary Jacobs, who turned herself blue with it. The pharmaceutical industry became her publicist.
A “treasure chest” of threads has proven to be of great interest. I am pleased that they chose to put “the art of making colloidal silver” at the top of the list. Here is the proper link to that thread:

That thread is the only source of information about colloidal silver open to everyone with no influence from advertisers whatsoever. Everyone and anyone involved with colloidal silver, its manufacturer and uses, are invited to post.
As you will gather from the thread, I tried to encourage people to use my manual generators to experiment as I had been doing. The object was to obtain the highest PPM without going yellow. I had found that I could do this manually to a degree equal or better to anything offered as an “automatic” generator.
There is no shortage of snake oil salesmen who will say anything in their quest for a quick buck. The advent of the Internet has given crooks the ability to make an impressive pitch to those unable or unwilling to do the research that unveils their deception. They make wild promises and fabricate endless testimonials. You find nothing but a PO Box when you try to track them down. The pharmaceutical industry makes every effort to dissuade the research community from discussing silver’s usefulness in medicine. They cannot patent silver. Therefore there is no profit potential. They are commercial companies. All that matters to them is their profit. There’s nothing good or bad about this. It’s a simple fact. We have to accept it.
That is why you need to make it yourself and make it properly. Follow the information you will find on this site. The fact is that it will work well for sinus difficulties.
