Colloidal silver research

Colloidal silver is a solution composed of solid silver particles suspended in distilled water. This substance may be used for a variety of purposes, from keeping liquids fresh to preventing serious bacterial infections. Research on colloidal silver supports many of its uses, both in the medical community and within other industries. For example, according to an article published in Frontiers in Microbiology[1], colloidal silver has verified antimicrobial properties. These properties stem from colloidal silver’s ability to adhere to microbial cells and penetrate inside them, altering the way they function. Some experts even suggest that colloidal silver could improve the effectiveness of a broad-spectrum antibiotic produced for medical use.

Because colloidal silver has been shown to be effective against bacteria, it is only natural to wonder whether it could be useful against viruses as well. For this reason, multiple research teams have been exploring this possibility for the past several decades. So far, findings have been mostly positive when it comes to colloidal silver’s antiviral properties. Research has shown that colloidal silver may even be effective against viruses. Below is some information about the existing research on colloidal silver.

Scientific research showing that silver can overcome viruses is more than thirty years old. Study after study found that the presence of silver stopped a wide variety of viruses in their tracks, interfering with the virus replication process. Thus, without the opportunity to grow, the viruses could not infect the host.

An article published in the September 1992 issue of Pharmaceutical Chemistry Journal reported that colloidal silver was effective against the smallpox virus. Depending on the concentration of nanosilver, smallpox particles were reduced by either 700 times (the weaker concentration) or 11,000 times (the stronger concentration).

A 2005 study reported in The Journal of Nanobiotechnology even more firmly established the power of nanosilver against viruses. Researchers from universities in Texas and Mexico (“Interaction of silver nanoparticles with HIV-1”, Jose Luis Elechiguerra, Justin L Burt, Jose R.) cooperated to conduct the experiments, which described as the first study of its kind. Capped nanosilver particles within the range of 1 to 10nm were created.

Capping mediums were one of three:

  • foamy carbon;
  • poly (PVP);
  • bovine serum albumin (BSA).

Capping is used to keep the nanoparticles from aggregating (clumping) so they remain their original size. The actual size of the nanoparticles depended on the capping method used. HIV-1, the virus that causes AIDS, was placed in containers, and the various amounts of capped nanosilver particles were added to each container. The containers were kept at 98.6°F (internal body temperature), and observations began. Within three hours, the virus was destroyed, regardless of the capping methods. Researchers theorize that the nanosilver particles bonded with the virus glycoprotein knobs. As mentioned above, this bonding stifled the virus from reproducing, thus causing its death. These results show that as long as they are capped, nanoparticles in the 1 to 10nm size range are effective against HIV-1.

There is an impressive 2010 US Government sponsored study performed through a division of US Army where they showed great activity in vitro against Arenaviruses, the Tacaribe virus family. There is a possibility this testing was performed as part of an initial search done for an antiviral agent, like an “antidote” or protection for the US Army. This study is as close to showing effectiveness against hemorrhagic viruses and Ebola type viruses as possible without endangering the lives of the researchers. This study showed great effectiveness of coated and non-coated nanoparticles against those viruses. The effective concentration was about 50 ppm and it took hours or about a day to destroy the virus. The study is listed on the reference list at the end of the book however if one googles “nanoparticles” and “Tacaribe” it will show on top of the search.

In a 2011 review[2] of available studies, researchers found a wealth of evidence indicating that silver nanoparticles can have an effect on enveloped viruses, regardless of whether the virus has a DNA or RNA genome. In a study[3] entitled “Antiviral Properties of Silver Nanoparticles on a Magnetic Hybrid Colloid,” researchers also discovered that silver nanoparticles have a potential for both antimicrobial and antivirus purposes.

New viruses are constantly emerging, and one such group is coronaviruses, so named because the viruses resemble halos when viewed through an electron microscope. In 2002, severe acute respiratory syndrome (SARS), a coronavirus, was a major global concern. SARS spreads rapidly, places great strain on the respiratory system, and can be fatal. Although things have calmed down considerably on the SARS front and no new cases have been reported since 2004.

Next was Middle East respiratory syndrome coronavirus (MERS-CoV). The virus first appeared in 2012. Research has found that this virus spreads by landing on surfaces and waiting for victims to make contact. For example, a lunch counter infected with a coronavirus is touched by people picking up their food. The virus is transmitted internally when the hands then place food in the mouth, scratch the nose, etc. The next frightening and potentially fatal coronavirus is always waiting in the wings.

To combat coronaviruses and future generations of unknown contact viruses, industry and medicine are combining to produce a range of surface coatings, be they plastic or paint. Regardless of the form, the common factor is the inclusion of nanosilver. When these mixtures make contact with humans, through touch, for example, the embedded nanosilver emits silver ions. These ions destroy any virus that lands on the surface, and some even enter the human body and work there.

“As time passes, more and more studies pit colloidal silver against other viruses. The results consistently come back in favor of the nanosilver. Some healthcare professionals take a strong stand for colloidal silver. Despite the lack of government backing, they recommend nanosilver as a remedy for swine flu (or any other flu) and as a weapon against the predicted viral pandemics that we may face in the not-so-distant future.”

It is important to note that multiple research studies[4] also show that colloidal silver can be toxic when used improperly or consumed in the wrong form. For this reason, it is important for people who want to take advantage of the positive effects of colloidal silver to choose the appropriate product and use it only as recommended. Any concerning side effects should be reported to a medical professional.

Can Colloidal Silver Kill Viruses?

How does colloidal silver kill viruses?

Viruses work inside the human body by invading cells, taking control of the nucleus and then using the cell for replication. When the cell is infected with a virus, it becomes more primitive and delicate in structure, making it easier to destroy. When put into close contact with colloidal silver, researchers have found that viruses can be effectively destroyed in a matter of minutes. Many researchers believe that colloidal silver destroys viruses in the body by interrupting the replication process.

“Even outside the body, colloidal silver can still destroy viruses. When used to treat surfaces, this substance can severely limit the ability of most viruses to survive and infect a host. In fact, even the government has recognized the truth about colloidal silver and viruses. The EPA is just beginning to realize the antiviral properties of silver, as is evident by the availability of a liquid spray disinfectant that consists of 30ppm silver.”

This spray is EPA-approved for businesses and industry, including educational facilities such as daycare centers, schools, and gyms. What’s especially interesting is the stated effectiveness: Garden variety (regular) bacteria are killed in thirty seconds with a residual kill time of twenty-four hours. Residual kill time is essentially how long the product remains active on the surface. Therefore, for up to twenty four hours after application, the disinfectant spray will continue to kill bacteria that reach the sprayed surface. For tougher bacterial strains such as MRSA (Methicillin Resistant Staph Aureus) and VRE (Vancomycin Resistant Enterococcus), the kill time is two minutes. In regard to HIV-1, the kill time is thirty seconds.

Using colloidal silver safely

Based on the available research, it is clear that colloidal silver has many potentially useful properties. One such property, specifically the ability of colloidal silver to destroy a virus or another type of pathogen, is particularly interesting in today’s world. However, it is important for anyone considering the use of colloidal silver for prevention or cure to consider the potential for side effects and complications. For example, in high concentrations, colloidal silver can be toxic. It may also cause a rare side effect known as argyria, which causes the skin to take on a bluish tone.

However, when using a safe colloidal silver product, the risk of serious side effects is low. Many of the studies carried out to determine the safety of silver ingestion use silver nitrate, which is much more concentrated than colloidal silver. Even when ingesting high amounts of colloidal silver, the bioavailability of this substance within the body makes it difficult to accumulate a dangerous amount. Exceptions occur when the particles of silver consumed are particularly large or irregularly shaped. These large and irregular particles are more likely to accumulate in organs and other tissues, leading to inflammation and other effects of toxicity.

“You can use colloidal silver to support your immune system and kill viruses safely by choose a product that has been properly refined and tested.”

Coated Silver: Support for your immune system

In addition to combating viruses directly, colloidal silver may also boost the effectiveness of your own immune responses to viruses and other dangerous pathogens. Silver particles may be beneficial to the immune system in several ways. Specifically, these particles may improve your immune system’s ability to recognize dangerous pathogens, allowing your body to eliminate them before they are able to cause a serious infection. Silver particles may also enhance the effects of antibiotics taken to fight off an existing bacterial infection.

If you are interested in using colloidal silver to support your immune system and/or prevent viral infections, it is important to choose an effective and reliable product. Colloidal silver may be available from a wide variety of manufacturers and sources, and not all of these products will offer the same benefits. Perhaps more concerning, some products with poor design or quality control may even be dangerous. Coated Silver is especially formulated with a high concentration and a small, uniform particle size. Each tiny particle of silver is individually coated to ensure maximum safety and effectiveness. This antiviral liquid can be dissolved in almost any liquid, allowing you to choose the delivery method that works best for you. With coated silver, you can improve your immune function and protect yourself from viruses with little to no health risks. Contact us to learn more or place your order today!
