I have asthma and bronchiectasis (Chronic Obstructive Pulmonary Disease). Was diagnosed 8 years ago. I was suffering from monthly (sometimes twice monthly) chest infections, and had to take antibiotics for every outbreak and becoming more and more resistant and sensitive to the drugs. I started using Colloidal Silver in my nebuliser (5ml, 3-5 times per day) about a year ago now and have not had a chest infection since. As soon as I feel my sputum changing (from clear to yellow) I use the colloidal silver and the infection does not develop any further. Some times I have to do it more than once, but mostly once is enough. I hope this will help anybody out there that is struggling with the same problem. Good luck!!

Colloidal silver works on chest colds very well. I had used CS for years, making my own beginning 18 years ago but on occasion the cold would get to lungs where I'd get terribly sick. Then upon this happening seven years ago I mentioned to my wife if a nebuliser with the silver might work. She went out and bought a nebuliser at Walgreens. This kind has a plastic mold that fits around the nose and mouth. You breathe in the steam DEEPLY for five minutes. Repeat four hours later. Do that for two or three days. The infections have never gone further than when I started the nebuliser. Soon, in two or three days the upper respritory infection is gone.

This discovery has been a God-send to me because I am so susceptible to sinus infections dropping to lungs.

I've used both ionic and nano (30ppm) and the nano is very effective both topically and orally. The ionic did nothing. I've also read many reviews stating nano is the way to go. Most recently I put 5ml of nano colloidal silver into a nebulizer to treat a nasty case of bronchitis. It worked really well and I was better in about 4 days.

You can buy Colloidal Silver (CS) from health food stores. For a cough you can try gargling 10ml for around 1-3 minutes then spitting it out, two or three times a day. Or, if it's down in your lungs, I suggest buying a nebuliser machine from the chemist, pouring 5ml of CS into the nebulising chamber and nebulising for 5 minutes, 2-3 times per day. This is what has worked for me!

Two weeks ago I had bronchitis setting in. Then two days after I started getting the bronchitis, I woke up with a raging, burning sore throat and felt so ill, that I was thinking about calling in sick for work. Desperate, I grabbed the my Colloidal Silver that comes with an eyedropper, tilted my head back and squirted it across the back of the roof of my mouth, letting it run down into my throat. (Only used about 1/4 dropper). Within literally seconds, the pain was easing! The left side more so than the right and realized that I used more on that side than the other.. So I reapplied more to the right. Sure enough, both sides were now feeling nearly perfect! It was so fast, it was astonishing! And, I am not talking about a little better... I mean the pain completely gone! I waited a few more minutes and to be on the safe side, applied it one more time. About three hours later, a little discomfort started back up, so I reapplied it again, and once more, had the same results. Discomfort gone in no time at all. Kept up with the silver every six hours after that for next three days, making certain it was completely gone. Now, what was crazy, was that I hadn't even noticed nor thought about the fact that my bronchitis had also cleared up! This stuff is an absolute Godsend! It will heal a canker sore lightening fast and I also recently used it on what I thought was a brown recluse spider bite. Both issues disappeared in no time! (Used food-grade hydrogen peroxide also on bite). Please note: Most colloidal silvers sold today are in the 20-40 ppm range and I would think, probably would not work. The 500 is very concentrated yet safe, even for children. This is a must have in every medicine cabinet!

Hi Rob,

I would agree with you about adding a few drops of hydrogen peroxide to colloidal silver. I have also read other "opinions" from research, who say that hydrogen peroxide causes colloidal silver particles to agglomerate. I'm sorry but I just don't believe that.

However, I will always believe what Ted from Bangkok has to say about colloidal silver because he is a qualified biochemist and researcher, who has no reason to lie.

Here's what Ted says about the benefits of adding drops of hydrogen peroxide to colloidal silver:

"Agyria is a common problem with using a straight batch of colloidal silver, often the skin is not really blue, it is closer to gray color. The problem occurs when a free silver ions react with the sulfur in your body to from AgS, or silver sulfide. Most colloidal silver produced are actually either a nonreactive Ag or a reactive Ag with a charge, then it reacts with the body's available sulfur to cause a "blue skin", more more accurately is "gray skin".

This problem can be prevented, which I solved over a decade ago, which required that a couple of drops of hydrogen peroxide is added to a liter of colloidal silver. The peroxide, reacts with the FREE silver ions to form Silver Oxide. When I first add this, I get a cloudly solution, and after three days, this cloudy solution becomes a clear white transparent water. However, an unreacted Ag or Silver in a solution will show itself is a faint yellow transparent solution. So this ia an easy way to tell. If you add a drop of H2O2 into this it becomes cloudy. However, if the solution is Silver oxide, it won't become cloudy as there is no longer any "free" silver ions. When they are no longer free, it won't react with the body's sulfur to form silver oxide. Hence, if a hydrogen peroxide, at least, is added to the colloidal silver you buy, the silver is no longer free, and the condition of blue skin or gray skin or agyria is prevented.

However, there is ANOTHER way, that DOES NOT REQUIRE you to wait for three days to fully digest the free Silver. When I make a batch of colloidal silver, using the silver wire or silver rods as an electrode using any D.C. adapter, the BEGINNING solution is distilled water with a 0.5% H2O2 concentration, which is 1/2 percent H2O2 concentration, or approximate amount such as one tablespoon (plastic spoons!) of 3% H2O2 in a 1 or 1.5 liter of colloidal silver is generally sufficient, to prevent any free metal silver form occuring..."

I pour 1 teaspoon of colloidal silver into the nebuliser cup, turn the machine on and breathe deeply for 5 minutes. I repeat 2-3 times per day (morn, noon, eve) for 3-4 days. When starting, I only breathe it for 2 minutes as I find I can get a headache. Great for lung infections and bronchitis.

Hi amr2003,

I use one of the smaller ultrasonic humidifiers to use colloidal silver nanoparticles. It can run on as little as 2 ounces of CS. The larger units may not be able to run on just 2 ounces of CS. I think my unit can only handle 500 ml.

I inhale directly from the output port of the humidifier. I alternate between mouth and nose breathing and I use it for 7 to 10 minutes per use and usually 3 times per day. I use new CS for each use as the ultrasonic effect causes agglomeration of some of the silver which appears as little black specs on the floor of the reservoir. So I never reuse the leftover CS in the reservoir. I use new CS with each use. So I am using 20 ppm silver nanoparticles which are yellow in color and I do not dilute with water.

I think Amazon has cool mist humidifiers as small as around 8 ounces to 500 ml, but the bigger ones are the most common.

Hello Teejay,

I am a Nutritionist of 22 years and I agree with the person who told you to take 5000 iu of vitamin d3 it is based on weight 150 pound for 5000 iu. So a 200 pound person would have to take 10000 iu. So if you're not taking it start now. It will take a few months to raise your blood level to be where it has to be. it's also great for pain only at these levels and dose is the proper dose. I learned it from a Doctor by the name of Dr. Richard Becker. I hope this will help you don't give up and keep trying to help yourself and God Bless take care

I don't agree….

I learned that mixing CS 10ppm with 3% H2O2 from Canadian Herbalist during the plandemic increased its effectiveness 100 times.

Colloidal Silver with Hydrogen Peroxide is sufficient to increase the efficacy of colloidal silver by up to 100 times against bacterial infections.

Per Art's email:

Hi Rob

This is how Chat GPT describes the reaction of silver nanoparticles and the potent oxidant H2O2 :

1. Oxidation and Dissolution of Silver Nanoparticles

Hydrogen peroxide can oxidize metallic silver (Agâ) into silver ions (Agâ):

Ag0+H2O2→Ag++OH−+OH•text{Ag}^0 + text{H}_2text{O}_2 rightarrow text{Ag}^+ + text{OH}^- + text{OH}•Ag0+H2O2→Ag++OH−+OH•

The oxidative dissolution process reduces the size of the nanoparticles and can eventually destroy them.

This occurs more rapidly at higher H2O2 concentrations and in acidic or neutral pH.

The generated hydroxyl radicals (•OH) are highly reactive and contribute to further degradation.

This is how Google AI describes the reaction :

Yes, hydrogen peroxide (H2O2) can cause silver nanoparticles (AgNPs) to break down and, depending on the conditions, can lead to their agglomeration or other morphological changes. This occurs through a redox reaction in which hydrogen peroxide acts as an oxidizing agent.

H2O2cap H sub 2 cap O sub 2 𝐻2𝑂2 . Without their protective layer, the nanoparticles lose their repulsive surface charge and are more susceptible to clumping together (agglomeration) due to van der Waals forces.

I have previously tested this reaction and the yellow nanoparticles turn almost instantly from yellow to clear and colorless as I add the H2O2 to the AgNPs suggesting a return to ionic silver. Once added together the clear solution slowly turns gray and eventually you see tiny black specs forming on the floor of the container indicating the silver has agglomerated and has gotten too large to remain in suspension. The AgNPs are no more and no longer have their potent antimicrobial effects.

I just retested this mixture again by adding H2O2 to some 20 ppm AgNPs that I had. Again, the same reaction, the yellow AgNPs turned clear after the addition of the H2O2 and with a little more time the mixture will start to turn grey as the silver starts to agglomerate and fall to the floor of the container.

During the initial pouring of the H2O2 into the AgNPs I would expect the mixture to be highly deadly to pathogens due to the highly increased level of hydroxyl radicals caused by mixing the two agents along with the potent antimicrobial activity of the silver ions and the H2O2, but also quite destructive to normal cells. During this reaction, you don't know exactly what you have at any given time point as the silver is agglomerating and for me personally, while the pathogen killing effectiveness may be temporarily increased, so is the negative impact to normal cells, which in my opinion could be dangerous especially occurring in the lungs which was the original intended use by the poster, amr2003.

According to the science shown above, another feature of this mixture is that the silver particle size initially shrinks before the agglomeration process starts. I am starting at a particle size in the range of 12 nm to 20 nm with my yellow AgNP solution. Particle size below 10 nm becomes very toxic to normal cells, so this is another problem with this mixture.

I don't doubt that this mix can increase the pathogen killing power of the mixture by 100 times over AgNPs, but this mix is not going to just ignore normal human cells and the alveoli of the lungs seem like a really bad place to find this out!

I personally would not use this mixture as an antimicrobial or otherwise.

@ Bill (Philippines) and Art (California)

Glad I always copy & paste interesting information. Here is what was posted in Canada.

Silver Complete Plus
Colloidal silver combined with H2O2 (food grade hydrogen peroxide) is quickly proving to be an effective combination. This combination can be used in oral and external treatments. Adding H2O2 to a completed batch of colloidal silver ionizes silver particles remaining in the solution. According to Water and Science Technology, a 2000:1 solution of colloidal silver to H2O2 is sufficient to increase the efficacy of colloidal silver by up to 100 times against bacterial infections.

High H2O2 colloidal silver strengths can be used externally with fine results. A 1.5% H2O2 colloidal silver solution can be used as an excellent disinfectant and water treatment method, and can be used as a skin cleanser/conditioner for healthy skin tissues.

Using colloidal silver to augment H2O2 therapy, a 2000:1 colloidal silver to H2O2 solution is created. For external use and for use as a mouthwash, the 1.5% solution need not be diluted. The H2O2/colloidal silver external solution is EXCELLENT to treat ear conditions and infections that use the inner ear as an "incubation chamber".

Hi amr2003,

The potent oxidant action H2O2, will cause the silver nanoparticles to agglomerate turning from the active yellow color to the inactive gray color. If you plan to use both, they will have to be used separately at alternating times.

Hi Madelyn,

In case you don't here back from the original poster, I believe Earth Clinic sells the yellow/gold silver in their merchandise shop here :

https://www.amazon.com/stores/page/E6CB2FEF-8467-4823-8193-06EFA0A010B7?ingress=3

You can't see the color because EC puts their CS in a brown glass bottle. A picture of it in a clear glass illustrates the yellow/gold color very well. Maybe they will add a picture like that someday as part of the product image! Their colloidal gold is the ruby red color, as it should be and an image of that in a clear glass would be helpful also!

Thank you Art,

Yeah, found one at amazon. It is small with 250ml capacity. Tiny, will see it it works... Do you know whether the yellow colloidal silver can be mix with H202? I read some place that it was supposed to make it more potent, but maybe that was for the ionic silver?

Thanks again for the great info...

Hello, Does anybody know the concentration of CS used with the ultrasonic humidifier? The introdu tion/beginning explanation says 2ounces of CS, my humidifier usually takes a gallon of water. So, would that be just 2ounces in a gallon? seems tiny, please elaborate. Thanks

The question here is, are we talking about true colloidal silver or ionic silver? Much of the stuff sold as colloidal silver is, in fact, ionic silver, not suitable for internal use at all. True colloidal silver is a bright golden colour. Ionic silver is clear.

Thank you for this distinction. I was not aware. I recently purchase new CS not even knowing there is a difference and it is golden where as the older CS I had was not. I refilled my spray bottle with the new stuff so essentially mixed the two together. Should I throw it out and just fill it with the new CS or is it ok that I mixed it? It is probably 70/30 with the 30 being ionic.
