Well, apparently the marketeers have jumped on the band wagon for silver's antibacterial qualities. I know this aspect of silver has been discussed in other threads in this forum somewhere - not to mention the toxicity of silver covered by that wonderful thread about the little silver balls used for decorating cookies

Anyway, the latest thing in new upscale products is to incorporate a bit of silver as a nod to the war against germs. Silver is being put into everything from washing machines to plastic food containers. One owner of the plastic food containers raves that they keep strawberries fresh for two weeks. A bar of soap infused with silver (the Cor soap), by the way, sells for $115 a bar. I'll take my silver in the form of flatware, holloware or jewelry, thank you!

For more on these products, you can read an article called "This War Against Germs has a Silver Lining" in the Wall Street Journal dated June 6, 2006.

Well, the silver in some of these products is often more than just a notional [marketing] nod. Silver burn/wound dressings often are much more effective than alternate choices, the silver coated threads in socks really do help prevent foot odor, etc. These unrecovered uses will spur demand, likely raising the metal's price over time.

No doubt there is some actual benefit to including silver in some of these products. Using silver for antibacterial purposes has gone through many cycles of popularity because there is some solid basis to the claims. Guess I'm just naturally skeptical when the usage becomes inordinately high along with the prices of the underlying products.

Have any of our members actually tried any of these products?

Here is another news item about the antimicrobial/anti-fungal properties of silver:
    "Those still brave enough to exercise outdoors might benefit from Vancouver-based Lululemon's latest contribution to technical exercise wear – a garment that doesn’t absorb the unpleasant smell of sweat. The Silverescent line, launched recently at Lululemon's 40 stores, combines the retailer’s body-fitting designs with fibre enmeshed with silver. Odor-inhibiting workout wear made from the metal-woven fibre has proved so popular that the company has had trouble keeping it in stock….."

Miracle Food Storage Containers
Are Naturally Anti-Germ, Anti-Mold & Anti-Fungus

...... infused with naturally antibacterial silver nanoparticles — it's easy to keep foods fresher three or even four times longer — fruits, vegetables, herbs, breads, cheeses, soups, sauces and meats! Try FresherLonger ™ and prove to yourself what we proved to ourselves in our own homes when we discovered these Miracle Food Storage containers.

......containers are infused with silver nanoparticles because silver (yes, the metal found in silverware) is safe and naturally anti-germ, anti-mold and anti-fungus. In tests comparing FresherLonger to conventional containers, the 24-hour growth of bacteria inside FresherLonger™ containers was reduced by over 98 percent because of the silver nanoparticles!

Compared to regular containers, FresherLonger™ Miracle Food Storage containers with silver nanoparticles reduce the growth of microorganisms by over 98 percent!

Real silver — yes, the mined mineral found in silverware — is naturally anti-germ, anti-mold and anti-fungus.

Silver in microscopic particle form is a safe, medically proven antibacterial agent. That is why silver nanoparticles are infused into the polypropylene containers of the FresherLonger™ system.

Compared to your regular food storage containers, tests showed the 24-hour growth of bacteria inside FresherLonger™ containers — with antibacterial silver nanoparticles — was reduced by over 98 percent.

Created by advanced nanotechnology ("nano" indicating one billionth), these silver nanoparticles average only about 25nm (nanometers) in diameter — 25 billionths of a meter; one 200 thousandth of a human hair. Their natural color gives FresherLonger™ Miracle Food Storage containers their distinctive golden hue.

Note: Due to the antibacterial nature of FresherLonger containers, elimination of desirable "probiotic" bacteria in some products such as yogurt or acidophilus milk may occur. Although it will not affect the taste of your food, or its safety, the FresherLonger system is not recommended for storing these products.

I am glad to hear about the workout suits. Now I can buy one and quit working out. I just tell people thatI have just finished a decathalon and I do not smell because I am wearing an anti-stink suit. Of course I will have to go to the bother of sprinkling water on myself to simulate sweat.

Hello. This is my first post as a new member.

I read in another forum, New uses for silver's antibacterial qualities that there is a debate about the antibacterial qualities of silver. I hope I can contribute a little more information to this topic via this forum by saying that the antibacterial effect of silver is called the "oligodynamic effect" It was discovered by the Swiss chemist KW Nägeli in 1893.

He noticed that water stayed fresher in a silver goblet than that in a glass goblet. Water containers on long distance ships were sometimes silvered by electro-plating. There is even a basis in folklore in the if wine was put into a silver goblet it would reveal traces of poison.

I am putting this response here for the sake of the new member. Silver Sulfadiazine 1% cream is used on burn patients to treat potential infections. Burn patients are very susceptible to infections as the skin barrier has been compromised. At least 20 years ago tracheotomy tubes were sterling silver because of silvers antimicrobial/anti fungal properties. There are a number of other silver compounds in medicine.

Silver Lining to Fighting Germs
By Laura Johannes
WSJ

Copper and silver are making a comeback as germ-fighting agents. The metals have been known for their anti-microbial powers for more than a century, but they were eclipsed by antibiotics in the modern era. Now, due in part to technology that allows them to be woven into fabrics, copper and silver are showing up in consumer products.

Marketers of the products say infusing things as socks, pillows and mattresses with precious metals limit growth of bacteria, fungi and even dust mites. Cupron Inc., Richmond, Va., sells a copper-weave yarn it uses in its own socks and sells to other makers. Aetrex WorldWide Inc. sells socks woven with Cupron yarn ranging in price from $10 to $25. The Teaneck, N.J., company says the copper also helps eliminate odor in the socks.

A 2008 study of 56 chronic sufferers of athlete's foot found significant improvement in symptoms such as itching, swelling and scaling after 40 days of wearing copper-soled socks. The study, which was published in the journal Foot, was funded by Cupron and by Renfro Corp., a Mount Airy, N.C., maker of the socks sold by Aetrex and others. The research shows "some promise," says Philadelphia podiatrist Warren Joseph, but it needs to be repeated with patients randomized to either a control group or copper-sock group. If proven effective, a sock with anti-fungal properties could help in the maintenance of toenail fungus and athlete's foot, since the same fungus is the cause of both, he adds.

Bandages and gels containing silver, long used on wounds and burns in some hospitals, are now available for home use. Marketers say they kill bacteria resistant to standard antibiotic creams. Silverlon adhesive bandages, sold by Argentum Medical LLC of Chicago, to hospitals and to consumers on the Web, are made with medical-grade nylon coated with pure silver. According to company-funded lab tests, the bandages kill Methicillin-resistant Staphylococcus aureus (MRSA). They cost 75 cents each—about 10 times the cost of plain bandages, Argentum says.

Curad Silver Solution, a wound gel that costs about $6 to $8 for a half ounce, was shown by an independent lab to kill all MRSA in 24 hours, says maker Medline Industries Inc. of Mundelein, Ill. While it's true that silver is an antibacterial, the evidence that it prevents wound infections is "not very strong," says Loren Miller, director of the infection control program at Harbor-UCLA Medical Center in Torrance, Calif. More serious infections often go deeper than the skin, where it isn't clear any topical treatments penetrate, he says.

Even if the silver in your first-aid kit does kill MRSA and prevent infections, it's probably overkill, scientists say. "For the general healthy population, there is so little risk [of MRSA infections] that I wouldn't think it would be cost effective or helpful," says Elaine Larson, director of the Center for Interdisciplinary Research on Antimicrobial Resistance, supported by Columbia University School of Nursing.

With most cuts, it's sufficient to wash with soap and water and cover with bandages, doctors say.

For dust-mite sufferers and bacteriophobes, there's the silver mattress. The Dualcomfort Magnifico, $3,599 in queen size, has silver woven into its silk-and-cashmere mattress cover, which maker Magniflex USA Ltd., New York, part of Italy's Alessanderx SpA, says inhibits bacteria and dust mites.

There are no published dust-mite studies on this mattress. But a 63-household German study published earlier this year found that a German company's mattress and coverlet infused with silver resulted in a significant reduction in allergens compared with a standard mattress. The silver is believed to fatally affect the dust mite's digestive processes, says author Archim Neumayr, a paid scientific adviser to Wenatex Das Schlafsystem GmbH of Salzburg, Austria, which sells the mattress. Better independent research is needed, says Darryl C. Zeldin, acting clinical director of the National Institute of Environmental Health Sciences. Inexpensive mattress covers without silver work well in controlling dust mites, he adds.

A number of precious-metal products, including night cream, are marketed as reducing wrinkles. Cupron sells a copper-weave pillowcase it says will "reduce the signs of aging while you sleep" mainly because the copper aids in collagen production. Cupron says it also kills microorganisms on the skin touching the fabric. A 57-person Cupron-funded study published in 2009 in the International Journal of Cosmetic Science, found that sleeping on the Cupron pillowcase for a month resulted in a reduction of crow's feet and wrinkles compared with a control.

Yale University dermatologist Lisa M. Donofrio, who reviewed the study for this article, says it wasn't rigorously designed enough to be meaningful. But, she adds, it's true that copper is a factor in collagen production, and both the pillows and creams may "do a little bit" to help wrinkles. Cupron says unpublished studies have bolstered its claims.

Doctors say it's fine to try products with metal-infused fabric, but don't drink liquid products containing silver, some of which claim to keep you healthy. Severe side effects have been reported in the scientific literature, including several cases of people's skin turning blue.

I heard on the radio that medical professionals in the US & UK are very concerned about antibiotic resistant infections especially MRSA (Methicillin-resistant Staphylococcus aureus).

I was wondering if anyone could point me in the direction of any real scientific studies that show the benefits of silver in treating MRSA?

I have also heard Manuka honey, from New Zealand, has been successfully used to treat MRSA.

The radio report said medical professional are pleading with the pharmacies companies to get back to developing new more powerful antibiotics.

I don't suspect the pharmacies companies will put much research effort into Silver/honey as treatment because the pharmacies companies may end up with nothing to protect their investment.

Lastly, what is the difference between:

  • Ionic Silver
  • Colloidal Silver
  • Silver nano particles
  • Silver filings
  • Silver powder
  • Solid silver

Today I heard a two stories about an intended healthy use of silver that I hadn't heard before ... I don't recommend anyone even consider trying the first. On the other hand, I might test the second idea.
  1. Junkies will apparently recommend using a silver spoon to "cook" their "fix" because it is more hygienic.

    There are also stories about how silver spoon is not a good idea, but without explanation. The unexplained fears were because of the silver tarnish and silver oxide.

    From one junkie to another, the abundance of reasoning for using a silver spoon was that doctors use needles made of silver because it kills germs and prevents infection.

    Don't use drugs


This next idea I might try.
    2. Next time buying milk, instead of a half gallon, get two quarts with the same expiration date. Open both. In one put a clean silver coin/object (solid/sterling). Then close both containers and return same to the refrigerator.

    After a couple of days, start checking both containers. Supposedly, the milk with the silver will last longer.

Ha! I've been seeing articles about a study of how long the covid-19 virus lasts on various substance, including stainless steel (it was something like up to 3 days) and copper (only a few hours--my recollection is 4 hours, but that could be wrong).

I wanted to know: What about pure silver? What about sterling?

    What is the oligodynamic effect?
quote:

The oligodynamic effect was first recognised more than 150 years ago and refers to the fact that some metal ions kill or inhibit the growth of microorganisms. This effect can be observed at extremely low doses. Metals which exhibit the oligodynamic effect include mercury, silver, copper, brass, bronze, tin, iron, lead and bismuth.

Of all metals, the strongest effect is exerted by mercury and silver.
