Back in October 2001 the prestigious Health Sciences Institute pointed out
that nebulizing colloidal silver directly into the lungs (see this short
to nebulize colloidal silver) is one of the fastest ways of effectively
eliminating serious upper respiratory infections, including bronchitis and
One of their well-known health symposium panelists, Dr. Victor A.
Marcial-Vega, M.D., had discovered, while dealing with pneumonia patients,
that colloidal silver can be quickly and easily atomized into a fine mist
and inhaled into the lungs using a device called a nebulizer. The silver is
then easily carried into the human blood stream and from there directly into
the body's cells and tissues.
The apparent result was rapid and highly effective remission of pneumonia
symptoms, as the tiny silver particles in the colloidal silver killed the
infectious agents causing the pneumonia.
What's more, a clinical
study on animals was conducted several years ago in which inhalation of
silver nanoparticles appeared to provide miraculous protection against
In fact, in the above-linked article on this study, it was reported that
mice purposely infected with pneumonia bacteria easily survived the
infection when they were allowed to inhale silver nanoparticles once per
day, whereas mice with the same infection but which were
allowed to inhale silver nanoparticles all died.
While this is one of the very few clinical studies to date conducted on
inhaling antimicrobial silver, it does seem to offer profound hope that a
safe, natural way has been discovered to help staunch the devastating
effects of serious upper respiratory infections.
Not so Fast...
However...additional safety studies on animals have found that long-term
inhalation of silver into the lungs can lead to accumulation of silver in
the soft tissues of the lungs, as well as inflammation, reduced lung
function and other problems.
While these animal studies are not conclusive regarding the safety of
nebulizing colloidal silver into the lungs, they do indicate that until
safety studies are conducted, significant caution and common sense should be
utilized when considering such a means of delivering colloidal silver into
In just a moment we'll take a look at those animal safety studies, and
discuss their significance to humans. But first, for those who may be
unfamiliar with the idea of nebulizing, here's a brief overview:
Nebulizing: the Short
process of "nebulizing" certain liquid medications is chiefly used by
asthmatics who need to get their medications deep into the lungs as rapidly
as possible during the course of an asthma attack, or to prevent one from
But it can also be used with other liquid medications, as well as natural
liquid substances such as certain homeopathic remedies, or even colloidal
Here's how it works: A liquid medication is poured into a small basin, or
water well that's generally located in the neck of a device called an
When the nebulizer is started, the liquid is
aerosolized into a super-fine mist. And depending upon which
type of nebulizer you own, the mist gently emits through a small mouthpiece,
or through a mask that goes over the face.
As the fine atomized mist comes out of the mouthpiece, or the mask, it can
then be easily inhaled directly into the lungs. And from the lungs the body
can efficiently and effectively distribute the medication straight into the
blood stream, cells and tissues.
Obtaining a Nebulizer
Nebulizers are considered to be medical devices, so most commercial drug
stores or medical outlets want a prescription from your doctor before
they'll sell you one. However, people often sell them on eBay and other web
sites, with no requirement of a medical prescription.
So if you're adventurous, and you understand that this is highly
experimental and you're
to take personal responsibility for your own decisions, you can
easily pick one up for under $40 or so by going to eBay and using the eBay
Just search under the term "nebulizer" or "Omron nebulizer" and you're sure
to find one. (Omron is one of the top manufacturers of commercial
nebulizers. I have the Omron brand, but there are others you can get if you
One Doctor's Successful Results
Here's what the Health Sciences Institute told their members about
nebulizing colloidal silver back in 2001. (This was directly after the 9-11
attacks on New York City and Washington D.C., and subsequent anthrax
mailings; hence the references to anthrax):
"Just in his last decade of medical practice, Dr. Marcial-Vega has treated
hundreds of people with a variety of viral, fungal, and bacterial
pneumonias. And of all the available treatments, he has seen the greatest
success with nebulizer treatments using a colloidal silver preparation.
Silver has long been known for its anti-bacterial properties, and the
nebulizer allows the mineral to reach the lungs and kill harmful bacteria.
Now, in the face of the anthrax threat, he believes it can do the same thing
with anthrax spores.
'We are constantly filtering all kinds of bacteria through our lungs,'
explained Dr. Marcial-Vega. Normally, a healthy body is able to kill off any
dangerous bacteria on its own. But in the case of illness, like pneumonia,
or an especially lethal bacteria like anthrax, the body may need some extra
Dr. Marcial-Vega says there are no concerns about using this treatment
because colloidal silver has no toxicity and no side effects. He has used
the colloidal silver nebulizer treatments on infants, the elderly, and AIDS
patients with pneumonia and has seen great results. All have responded
quickly to the treatment even when no other approach seemed to help, and no
one reported any adverse reactions."
his web site, Dr. Marcial-Vega explains more about how to nebulize
-- Excellent for respiratory tract infections such as
pneumonia and bronchitis.
Put 15 cc (two teaspoons) in the included receptacle, turn on the machine
and breathe deeply and slowly for approximately 15 minutes or until all the
liquid is gone. Repeat three times a day for colds, pneumonias, bronchitis
If it makes you cough too much, add 20-30 grains of sea salt to the liquid
just before nebulizing and shake.
This is a natural antibiotic that contains water and silver in a colloidal
suspension. It is effective against bacteria, viruses and fungi."
-- Dr. Victor Marcial-Vega, M.D., former Clinical Assistant Professor at the
University of Miami School of Medicine from 1990 to 1994.
Unfortunately, Dr. Marcial-Vega doesn't state on his web site the specific
concentration of colloidal silver he uses when nebulizing colloidal silver.
But from what I've read on the internet, most people who nebulize colloidal
silver are using between 5 ppm and 10 ppm, with some daring souls going as
high as 20 ppm.
Use Caution and Common
In spite of Dr. Marcial-Vega's comment that "no one reported any adverse
reactions" during the numerous times he's used colloidal silver with a
nebulizer to treat various forms of pneumonia, you should always remember
that nebulizing colloidal silver is a HIGHLY EXPERIMENTAL procedure.
And just because "no one reported" any adverse reactions during short terms
of treatment, doesn't mean there won't be any over the longer-term if
inhalation of colloidal silver is continued on a regular basis. As we now
know, silver toxicity from excessive intake and long-term accumulation can
take years to show up.
I say that because literally ZERO
clinical safety studies have been conducted on this method of treatment with
colloidal silver. In other words, in the short-term, nebulizing colloidal
silver may be perfectly safe. But in the long-term, no one really
knows what the cumulative effects of nebulizing tiny silver particles
directly into the soft tissues of the lungs may be.
This is why I always state that if you intend to nebulize colloidal silver,
you should do so only with the clear and distinct understanding that
experimenting on yourself, and that nebulizing excessively (and
no one at this point knows what "excessively" is) might produce significant
negative consequences somewhere down the road.
Considering this, it makes sense to conclude that if you decide to nebulize
should limit your use of nebulized colloidal silver to only those times when
you feel it's absolutely necessary, such as for short periods of
time during an upper respiratory infection.
And even then, proceed only with due caution and common sense, and
preferably with your doctor's oversight.
Nebulizing colloidal silver should NOT be done on a regular basis as a
standard means of consuming colloidal silver. Until clinical research
demonstrates otherwise, the potential risks are just too great.
I know there are folks on the internet who say nebulizing colloidal silver
as a regular means of intake is "perfectly safe" as long as your colloidal
silver is made correctly.
There's even a gentleman who sells a conventional colloidal silver generator
along with a cheap nebulizer, who advocates the regular ongoing use of
nebulized colloidal silver.
But do yourself a favor: Write and ask the advocates of this process to show
clinical study on humans demonstrating that regular, long-term use of
nebulized colloidal silver causes no harm to the lungs.
Be sure to ask them to show evidence that nebulizing colloidal silver
regularly over long periods of time will not create argyria of the lungs, or
harm the cilia of the lungs. And finally, ask them for proof that colloidal
silver inhaled regularly over long periods of time will not pass through the
blood-brain barrier and accumulate in the brain.
They won't answer you, of course, because they have no such clinical
evidence. They just continue to tout the same, tired old canard that as long
as the colloidal silver is "properly made," there's no harm whatsoever no
matter how of it much you nebulize, or how often.
But remember, that's exactly what was said by cavalier colloidal silver
advocates about argyria back in the late 1980's and early 1990's, i.e., "You
can't get argyria as long as your colloidal silver is made correctly."
Well, a lot's been learned since that time. We now know that ongoing
use of even the very highest quality colloidal silver in the world can cause
argyria and other toxicity problems
if it is
used in excess, daily, for long periods of time.
Unfortunately, it has taken nearly two decades -- and a number of unhappy
argyria victims -- to come to this realization.
And yet there are
people on the internet claiming you can drink as much colloidal silver as
you want on an ongoing basis and it "can't harm you as long as it's properly
My fear is that eventually we're going to find out the same thing about
nebulizing colloidal silver regularly, over long periods of time, directly
into the tender, soft tissues of the lungs.
Maybe this fear is an unfounded one. That's quite possible. But to date no
one has yet satisfactorily allayed it with
clinical evidence that would prove otherwise. And I certainly
don't want to be the first colloidal silver user with "blue lung syndrome."
Animal Studies Demonstrate
The only two clinical safety
I'm aware of dealing with the inhalation of silver into the lungs were
conducted on laboratory rats.
Both studies used laboratory engineered silver nanoparticles, rather than
commercial colloidal silver. But the idea of what happens to silver when
it's inhaled daily into the lungs for long periods of time is what was
The first study was a 28 day study which concluded there was no significant
long-term harm to laboratory rats that were forced to inhale various levels
of silver nanoparticles for varying periods of time on a daily basis for
four weeks. That's
definitely good news. Very exciting!
The second study, however, was conducted on rats over a period of 13 weeks
(i.e., 90 days). It concluded that there were "dose-dependent
increases in lesions related to silver nanoparticle exposure, including
mixed inflammatory cell infiltrate,chronic alveolar inflammation,
and small granulomatous lesions. Target organs for silver
nanoparticles were considered to be the lungs and liver in the male and
female rats. No observable adverse effect level of 100 μg/m3
is suggested from the experiments."
In other words, at higher daily doses for longer periods of time there were
significant negative results including chronic inflammation of the alveolar,
i.e., the delicate air sacs deep within the lungs where oxygen is taken into
Also observed by the researchers were increases in inflamed cells, and small
nodules, or tiny lumps of inflamed tissue. And silver nanoparticles
apparently accumulated in the lungs and liver of the rats.
Interestingly, in this study there were no observable adverse effects at 100
μg/m3, or 100 micrograms of silver per cubic meter of air. Once
again, that's at least
encouraging news because it indicates that when silver is inhaled daily,
there apparently are levels of silver inhalation which
-- at least in the rat model
-- are relatively safe even when used for weeks on end. But beyond those
levels significant negative results were indeed observed.
The study researchers wrote:
The results...indicated that lungs and liver were the major target
tissues for prolonged silver nanoparticle accumulation.
...Based on the test article-related effects (minimal bile-duct hyperplasia
in males and females, chronic alveolar inflammation and macrophage
accumulation in the lungs of males and females, and erythrocyte
aggregation in females) reported in this study, we found a NOAEL of 100 μg/m3.
...lung function changes previously
reported from this study (Sung et al., 2008) indicate significant
physiological decreases in tidal volume
dose levels in males and minute volume decreases for all
dose levels in females.
The origin of the difference in effects measurements remains to be resolved.
This basically means that over the course of 90 days of inhaling the silver
nanoparticles each day, the tiny silver particles accumulated in the lungs
and livers of the rats.
What's more, the tiny air sacs in the lungs known as the alveoli became
inflamed, and as a result lung function was
significantly reduced. The reduction in lung function was higher
for male rats than it was for female rats in the study. The researchers
don't know why.
Finally, macrophage accumulation in the lungs of these rats would seem to
indicate the body was attempting to remove foreign substances from the
lungs, i.e., the accumulated silver.
A macrophage is a form of phagocyte. And a phagocyte is a cell, such as a
white blood cell, that engulfs and attempts to eliminate toxic substances,
waste material, harmful microorganisms, or other foreign materials in bodily
tissues as well as in the bloodstream.
Remember, these rats were
sick. They were simply inhaling silver nanoparticles. So there would have
been no reason for the body to send macrophages into the lungs except to
remove accumulated silver particles from the lung tissues.
This is similar to what's observed when people are exposed to inhalation of
asbestos on a chronic basis. The asbestos lodges in the lungs. And the body
sends in macrophages whose job is to attempt to rid the area of the
accumulated foreign objects by engulfing them.
In short, macrophages are the "clean-up crew" of the human body, and they're
called in when there's something to clean up.
This demonstrates pretty much beyond
any shadow of a doubt that silver particles, when inhaled regularly, over
long periods of time, can become embedded in the soft tissues of the lungs
and cause a decrease in lung function.
The Great Unknown...
Now let me emphasize these were animal studies,
human studies. People are not rats (well,
of them, anyway), and therefore you cannot necessarily extrapolate a
straight across correlation between what happened to the rats, and what
might happen to humans when nebulizing colloidal silver every day for 90
In humans it could result in no damage to lung function at all...or less
damage. We simply don't know for sure because
human studies have not been conducted.
And really, that's my entire point; the long-term safety of inhaling
silver into the lungs is simply
Also, it's important to note that these rats were exposed to what appear to
be ungodly levels of silver nanoparticles -- up to six hours a day in an
Even the study authors admit the concentrations of silver nanoparticles used
in this animal study were "difficult to relate to human exposures." That
usually means they were
So you can't take the study as "proof positive" that inhaling silver
directly into the lungs each day for 90 days is going to be as harmful in
humans as it was in the rats.
But then, when a person is nebulizing colloidal silver regularly, is there
really any way to know how much might be accumulating in the lungs over
the problem. Without human clinical safety testing, there's no way to know
for sure what's going on when you nebulize colloidal silver regularly. At
what degree is it safe? And at what degree is it potentially harmful?
To a reasonable observer, the study should confirm my hypothesis that
nebulizing colloidal silver is still a
experimental procedure with no significant human safety data
behind it, and that if undertaken, it should only be done so with much
caution, on a limited basis (if at all)
more is known.
Serious Lung Disease
Finally, it's very important to understand that nebulizing colloidal silver
may actually be
contraindicated for some people with certain serious lung
conditions or diseases, or in late-stage COPD or other conditions. So always
check with your bona-fide licensed medical practitioner before nebulizing
colloidal silver, particularly if you have a chronic lung disease of any
Nebulizing colloidal silver could
actually cause a serious (and perhaps even fatal) decrease in lung function
for some people, under certain rare but very possible conditions.
As an article on SilverMedicine.org points out:
"If an individual is incredibly weak due to a severe lung condition to the
point that breathing is laborious, do NOT use a colloidal silver oxygen
nebulizer or humidifier without a fully qualified medical staff present...It
is possible that the first treatment could arrest the breathing of the
individual being treated."
Finally, SilverMedicine.org warns never to inhale a silver product that may
have been combined with proteins, salts or other chemicals as it could lead
to silver poisoning. They don't give any citations for this claim, but it
seems reasonable to take it into consideration. In some forms, such as
silver nitrate and other silver salts, silver can be very caustic to any
soft tissues it comes into contact with.
Please Don't Shoot Me,
I'm Only the Piano Player...
I know some of the above opinions will leave me on the outs with many
colloidal silver advocates who see nebulizing colloidal silver on a regular
basis as a safe and highly effective way to get more silver directly into
the bloodstream, tissues and organs faster and more effectively than using
colloidal silver orally.
As I've already pointed out, some colloidal silver advocates -- such as Dr.
Victor Marcial-Vega -- apparently even build the bulk of their upper
respiratory treatment program around nebulizing colloidal silver. (Which is
fine, as long as the nebulizing is stopped after the treatment proves to be
either successful or unsuccessful. It is the
nebulizing of silver that appears to be potentially problematic.)
And as I've also pointed out, at least one colloidal silver generator
manufacturer has been building his entire program chiefly around nebulizing
colloidal silver, even supplying a cheap nebulizer with his generator and
telling people the best way to use colloidal silver is to inhale it directly
into the lungs.
I think this is potentially dangerous advice, however, because it encourages
people to nebulize colloidal silver
matter of course, rather than only occasionally, on an "as
needed" basis, if at all.
In my humble opinion, it is bordering on the irresponsible to recommend
inhaling colloidal silver into the lungs as a normal,
way to use colloidal silver. Doing so tends to negate the highly
experimental nature of the procedure, making it seem "mainstream" when
indeed it is clearly potentially dangerous until proven otherwise.
My Own Nebulizer Usage
For the record, I've personally nebulized colloidal silver for upper
respiratory infections, and generally to good effect. So have other friends
and family members. Indeed, on several occasions over the past 10 years
nebulizing colloidal silver has kept my wife -- who suffers on occasion with
a swollen and infected voice box -- off the prednisone and antibiotics the
doctors like to prescribe.
But as I've emphasized in this article, nebulizing colloidal silver is
something I'd do on a regular ongoing basis. Through reason and common
sense, I recognize it's a highly experimental procedure with very limited
clinical testing behind it, and ZERO human clinical safety data.
Indeed, as I mentioned earlier there have been
human clinical safety studies whatsoever. And as you've seen, the limited
animal safety data available indicates there's at least a
for silver accumulation in the lungs and perhaps even harm to lung function
if silver is inhaled into the lungs on a regular daily basis over a period
And therefore, as an experimental procedure, it's something I would do only
gingerly and with great restraint, and with the clear understanding in mind
that should I make the choice to nebulize with colloidal silver, any
negative consequences to my body are my
After all, knowing it's experimental should help you understand that when
you do it, you're
experimenting on yourself.
Again, I'm very conservative when it comes to nebulizing colloidal silver.
Some would say overly-conservative. So be it. I think that's the prudent
course considering the dramatic lack of human safety data available.
When I nebulize, I use only 5 to 10 ppm colloidal silver made with a
Silver Generator from TheSilveredge.com.
I nebulize colloidal silver
when I have an upper respiratory infection that feels like it's about to get
out-of-control, or when I feel unusually congested, which is rare.
But I don't overdo it. A couple or three minutes at a time, three or four
times a day, for a few days in a row, and I'm done. I may not nebulize again
for several months or even several years if I don't have any upper
respiratory issues to deal with.
Now that's just me. I'm not "prescribing" anything here. I'm just reporting
what I do. You have to make your own decisions and take personal
responsibility for them.
Other people nebulize colloidal silver much more frequently than I ever
would, and longer per session, and to date I haven't heard of
anyone having any negative
consequences. But I always like to err on the side of caution with something
like this, until I can see some bona-fide clinical research demonstrating
If It Ain't Workin'
Why Keep Doing It?
Finally, I feel it's important to note that on the very few occasions over
the past 10 years that I've nebulized colloidal silver for an upper
respiratory condition, it didn't always work.
Sometimes nebulizing colloidal silver was
effective. And sometimes it was decidedly ineffective. But in every single
case I've been able to tell whether or not it was helping
the very first day.
When the procedure proved helpful I experienced rapid remission of the
symptoms of upper respiratory infection and was feeling quite well after
using the nebulizer for only two or three days, at most. And when it did not
prove helpful right away, continuing the treatment for additional days did
not result in any discernible improvement whatsoever.
This demonstrates to me that when it works, nebulizing colloidal silver is a
very effective treatment that does not need to be carried on for weeks or
months at a time. And when it
work, continuing to nebulize colloidal silver is...well...unnecessary and
Indeed, if there's no sign of relief in the first few days of nebulizing, I
simply recognize it's not helping and I stop using the nebulizer and switch
to some other natural health protocol. Or go see my doctor if necessary.
Or, if I get some symptomatic relief, but after two or three days of
nebulizing colloidal silver it begins to look like the only way I can
the symptomatic relief is to keep nebulizing indefinitely on an ongoing
basis, then for the sake of safety I quit nebulizing altogether and choose
another route, i.e., some other natural health protocol, or even go to the
doctor and take the darned antibiotic drugs if I have to.
I'm simply not willing to risk nebulizing colloidal silver for long periods
of time, considering the fact that nobody knows for sure whether or not
there's a potentially
cumulative negative effect on the lungs from the tiny silver
For me, the bottom line is that no one really knows if the tiny silver
particles being inhaled into the soft tissues of the lungs daily, for long
periods of time, can ultimately become embedded in the lungs just like they
do in other parts of the body when used to excess.
So if you're nebulizing colloidal silver for weeks and months at a time to
keep a health condition under control, please consider that you may well be
Hey, it's your health and well-being that's at stake. So I'm not
telling you what to do. And again, I'm not "prescribing" here, I'm only
and I'm pointing out what I feel is abundantly obvious for those with
wisdom, common sense and discretion.
I'll write more on this topic again in the future, particularly if new
studies come out demonstrating the safety (or lack thereof) of nebulizing
In the meantime, I remain...
Yours for the safe, sane and
responsible use of colloidal silver,
