Colloidal Silver Medical Research Before 1940

Medical bureaucrats and other colloidal silver naysayers routinely claim that the modern-day use of colloidal silver constitutes “risk without benefit.”

They go on to claim ad nauseum that there’s no modern medical or scientific evidence for the efficacy of colloidal silver.

What They Omit

What the naysayers always fail to state is that there’s a very good reason for the dearth of modern medical and scientific research on behalf of colloidal silver:

The medical community has simply refused to conduct any significant new large-scale research on colloidal silver since the first patented antibiotic drug (penicillin) came into widespread medical usage in 1940.

In fact, since the advent of prescription antibiotic drugs, the medical community has not conducted any significant medical research on any natural substances with infection-fighting qualities, except for those they could synthesize and turn into patentable drugs.

Red-Headed Step Child

In short, even though colloidal silver was widely used by doctors and enthusiastically studied for its infection-fighting properties prior to 1940, directly after the advent of prescription antibiotic drugs colloidal silver quickly became the “red-headed step child” of the medical research community.

Except for a small handful of studies conducted at independent universities such as Brigham Young University

…plus a number of private clinical studies conducted by some of the larger colloidal silver distributors (most of which had to be conducted outside of the United States)…

… and a number of studies conducted by foreign researchers, or by cutting edge medical and scientific researchers who have bucked the American medical establishment and conducted independent research on their own (see discussions of many of these studies at Colloidal Silver Kills Viruses and Colloidal Silver Cures MRSA)...

…colloidal silver has been largely ignored by the medical research community in this country since 1940.

Prescription antibiotic drugs have become the de facto mainstay of modern medicine in regards to treating infections, in spite of the fact that researchers admit medical science is now losing the battle against infectious microorganisms.

Medical Research Before 1940:
the Evidence for Colloidal Silver is Overwhelming

Another thing the medical bureaucrats and colloidal silver naysayers don’t like to tell you is that when they say there is “no medical or scientific evidence” of efficacy for colloidal silver, what they’re talking about is modern medical research.

It is true that they have effectively quashed modern research into the use of colloidal silver.

But what they omit is that some of the very best medical and scientific research on colloidal silver was conducted prior to the 1940 advent of penicillin.

When you look back on the old pre-1940 medical literature, you’ll find that a wide range of infectious microorganisms and ill-health conditions were routinely treated by the medical community using colloidal silver. This of course was due to the incredibly broad-spectrum infection-fighting and immune-boosting qualities of silver itself.

The following is a list of pathogens and medical conditions documented before 1940 in which patients were successfully treated using colloidal silver.

As you can see, dozens of infectious microorganisms were known to be sensitive to silver, and numerous medical conditions were known to respond to silver treatment.

“I'm often asked which colloidal silver generator I recommend. Hands down, I recommend the Micro-Particle Colloidal Silver Generator from my friend Steve Barwick at Silver Edge…I've touted the benefits of pure micro-particle colloidal silver for years to anyone that would listen. Frankly, it's the best way I know to quickly heal cuts, scrapes, sores and burns... treat a host of common illnesses such as colds, flus and sore throats... as well as kill nasty germs on cutting boards, kitchen counters, tooth brushes and even your pet's water bowl. But most importantly is how it can protect you from the deadly pathogen MRSA that has become resistant to almost all known prescription antibiotics. Having a colloidal silver generator as part of your first aid kit just makes sense... especially if you ever find yourself in an emergency with no access to a doctor or hospital.”

-- Michael Cutler, M.D., Editor, Easy Health Options

"I believe the folks at The Silver Edge are the reigning experts on colloidal silver. Nowhere else will you find more accurate information on how to use colloidal silver to protect yourself and your family..."

-- Bob Livingston, The Bob Livingston Letter

"Thanks for all your brilliant work to educate people about colloidal silver. It is one of nature’s wonders that helps keep us well."

-- Dr. Keith Scott-Mumby, M.D., MBChB, PhD, author Cancer Research Secrets, Complete Parasites Handbook, and Survive Without Antibiotics

"Hi Steve: I have been a supporter of your work for nearly 15 years, and I have used Colloidal Silver for over 30 years without a single problem, EVER! I have cleared up feline herpes in a cat's eyes, and have prevented infection from countless cuts, post surgery, for other injuries sustained during daily life. It is the safest and best antibiotic, anti-fungal, anti-viral that I have ever used, as opposed to the pricey, worthless, side effects loaded junk that the pharmaceutical companies promote. Read the labels for the antibiotics and other "medications" prescribed by physicians, in good, albeit ignorant, faith, and you will find horror abounding in devastating diseases that they can cause you, including death. So, if anyone has any doubt about using natural Colloidal Silver in place of chemicals, think again. This works, with zero side effects."

-- Dr. Kathleen Olsson Nelson, RN, BA, MA, PhD, PhD, FSNPM, FCH., Clinical Psychologist and Nutritional Consultant

“The bottom line is that for colloidal silver to effectively fight pathogens, you must use micro-particle silver rather than conventional colloidal silver or silver protein products… You can actually make your own micro-particle colloidal silver in your own home. In fact, there’s one colloidal silver generator on the market today -- the Micro-Particle Colloidal Silver Generator from a company called The Silver Edge -- that will make colloidal silver with such uncommonly small silver particles, it requires a multi-million dollar Transmission Electron Microscope operating at 175,000x magnification just to see them. This generator allows you to make the most powerful, and highly bioavailable form of colloidal silver right in your own home. And you can make it for pennies…Having a Micro-Particle Colloidal Silver Generator on hand allows you to protect your entire family – and probably your friends and neighbors as well – for just pennies.”

-- Donald S. McAlvany, The McAlvany Intelligence Advisor, October 2013

“I'm so happy I own a Micro-Particle Colloidal Silver generator. No one should be without this wonderful device. I so very much appreciate you sharing your knowledge about colloidal silver.”

-- Gary C. King, best-selling author of Blood Lust: Portrait of a Serial Killer and other true crime books and stories
