BYU study shows colloidal silver is as good as penicillin

Tests of a colloidal silver solution have concluded that it provides an alternative to antibiotics.

 Researchers in Brigham Young University’s department of microbiology were asked to test the antimicrobial activity of Colloidal Silver. Silver is “colloidal” when it is suspended in small amounts in liquid. Silver in various forms has been used for centuries as an antimicrobial agent. In the 1800s and early 1900s, people put silver coins in their water barrels to kill microbes and make the water potable. A silver nitrate ointment is applied to the eyes of newborn babies to prevent certain eye problems. And silver sulphadiazine is regularly used to treat burn wounds.

 Use of Colloidal Silver, once common, faded with the advent of antibiotics. Recently, though, concerns about overuse of antibiotics and the development of antibiotic-resistant microbes has lead to a resurgence of silver’s popularity.

 And with good reason, according to the study, conducted by BYU’s David A. Revelli, microbiologist, and Ron W. Leavitt. The study compared Colloidal Silver to five classes of antibiotics: the tetracyclines, fluorinated quinolones (Ofloxacin), the penicillins, the cephalosporins (Cefaperazone) and the macrolides (Erythromycin).

 Both the silver and antibiotics were tested on a variety of microorganisms, including streptococcuses, pneumonia, E. coli, salmonella, shigella  and others.

 According to the study, silver “exhibits an equal or broader spectrum of activity than any one antibiotic tested.” Where each antibiotic was effective against specific susceptible organisms, silver “is equally effective” against both gram positive and gram negative organisms.

 ”The data suggests that with the absence of toxicity associated with Colloidal Silver, in general, and the broad spectrum of antimicrobial activity of Colloidal Silver, it may be effectively used as an alternative to antibiotics,” Revelli and Leavitt wrote.

 Dr. Dianne Farley-Jones, a family practitioner, recommends Colloidal Silver to her patients for external problems. She hasn’t used it internally much, though she said it works quite well for ear infections. “With any kind of abrasion or skin problem, it works really well and really fast. And it seems to have an anti-inflammatory effect, though that hasn’t been proven.”

 Colloidal Silver also seems to have an antiviral effect, Farley-Jones said. She’s used it at different times but hadn’t recommended it until she saw the BYU research data. Now she encourages patients to use it as a nasal rinse for sinus infection or to spray their throats if they feel like they’re getting a viral sore throat.

 Antibacterial Product Testing Results Summary 

 The following results suggest that Colloidal Silver is a broad spectrum antimicrobial agent – it is able to effectively stop the growth of, and in fact kill, a variety of bacteria. 

 Colloidal Silver has been tested against the following organisms. 

 > Staphylococcus aureus (Pneumonia, eye infections, skin infections (boils, impetigo, cellulitis, and post-operative wound infections), toxic shock syndrome, meningitis, food poisoning, osteomyelitis, and many others) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/22/99 BYU Report.

> Salmonella arizona (Food poisoning, etc.) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/28/99 BYU Report.

> Salmonella typhimurium (Food poisoning and enteric fever) inhibited and killed at a concentration of 2.5 ppm. 6/7/99 BYU Report.

> E. coli (Food poisoning, urinary tract infections, traveler’s diarrhea, diarrhea in infants, respiratory tract infections, and wound infections) inhibited and killed @ 2.5 ppm. 1/22/99 BYU Report.

> Haemophilus influenzae (Otitis media (ear infection), pneumonia, meningitis, throat and sinus infections (including epiglottitis in children and sinusitis), and suppurative arthritis in children) inhibited and killed @ 1.25 ppm. 1/22/99 BYU Report.

> Klebsiella pneumoniae (lower respiratory tract infections, nosocomial infections (infections spread in hospitals), urinary tract and wound infections, and bacteremia) inhibited and killed @ 2.5 ppm. 1/28/99 BYU Report.

> Klebsiella oxytoca, (Similar to those infections caused by K. pneumoniae) inhibited and killed at a concentration of 2.5 ppm. 6/7/99 BYU Report.

> Pseudomonas aeruginosa (severe burn and wound infections, keratitis, pneumonia, meningitis, nosocomial infections, urinary tract infections, etc.) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/22/99 BYU Report.

> Streptococcus pneumoniae (pneumonia, meningitis, sinusitis, otitis media (ear infection) inhibited @ 2.5 ppm and killed @ 5 ppm. 4/21/99 BYU Report.

> Streptococcus pyogenes (skin infections, upper respiratory infections (i.e. strep throat) impetigo, hospital-acquired infections, scarlet fever, etc.) inhibited and killed @ 1.25 ppm. 1/22/99 BYU Report.

> Streptococcus faecalis (Urinary tract infections, endocarditis, wound infections, etc.) inhibited @ 2.5 ppm and killed @ 5 ppm. 1/22/99 BYU Report.

Our tests demonstrated the same results!

You can see our FDA-certified independent lab tests on some of the worst pathogen know the humanity. Not only were the scientists who conducted our tests amazed, so were we!

      This article is highly misleading. These effects were noted in agar plates (petri dishes) and not in the human body. Many compounds work outside the body (in vitro) while having no effect inside (in vivo). This is a critical distinction the author purposely left out with the express intent of distorting sound science in order to scam you out of a buck (or a few thousand).

      Furthermore, I doubt anyone familiar with microorganisms would make the claim that anything would cure an ear infection without a huge smirk on their face. Medications, including antibiotics do nothing for an ear infection. They simply cannot be touched by medicine. The body takes care of that itself.

        Do you truly expect anyone to believe “anonymous” over Brigham Young University scientists?

        Also, not agreeing with the author does not mean it is a scam; it means you do not agree, which is fine. Please reframe from insults; recess is over now…

        As far as the author’s intention; presuming to know is exactly like guessing, thanks for your guess…. :wink:

          No. I expect them to believe science. Anyone here can take the info I provided and check it out for themselves. It’s not hard. Do you expect ad hominem attacks will gain your snake oil some credit?

          Dare I comment on the bias of the named “scientists”?

          What I posted is not a matter of personal opinion. It is fact.

      Anonymous wants us to trust big pharm and has been drinking too much floride in his water.

      antibiotics won’t work much longer due to over prescription in the 1960-90′s and because meat is being pumped full of the stuff so you had better hope silver is some use else we will be dropping like fly’s in ten years time.

      Nano-bots might come to our aid as we become less human and more machine

        That’s good. Set up a straw man and send me after a red herring. Don’t come at me with unrelated nonsense. My statement stands and facts are facts. I’ve personally tested colloidal silver against many other compounds in the lab. Indeed, silver has great antibacterial properties in a setting outside the body but it simply does not work well inside the body.

        I’ve seen it with my own two eyes. I’ve actually done it using science!

        I couldn’t possibly argue against silver as a topical solution (against ACTUAL organisms) but ingesting it can be harmful if nothing else. There is no big grand conspiracy here. Take an introductory microbiology class at your local community college and see for yourself!

        • Danser

          Humans have been drinking colloidal silver for 2,000 years; it does work in the body and you need to do some homework. Your own two eyes lied to you.

          I spend thousands every year on FDA-certified lab tests and we can not find a pathogen we could not kill quickly and safely. 5 independent toxicity tests demonstrate zero toxicity, so what are you going on about?

          What Community College did you graduate from?
