Colloidal Silver Can Kill Any Infection—How To Use It Safely

colloidal silver benefits

Silver has been an essential component of natural healing doctrines since ancient times, millennia before the discovery of antibiotics. For instance, Persian kings used to carry their water in silver containers to avoid contamination and keep the liquid fresh at all times. This is the same reason why copper vessels were used in ancient days.

Fast forward to the modern era, in the 19th and early 20th centuries, silver wires were used to suture wounds, protect burns from infections, and even to make urinary catheters that could be used with low risk of complications.

With the advent of penicillin in 1942, silver assumed a secondary role but has been gaining huge popularity over the last 10-20 years in the form of colloidal silver, a modern and fabulously effective treatment with virtually no side effects—a feat that no antibiotic can really brag about.

But is it really THAT effective? Is there any scientific evidence to back these claims? And what is the right way to take it? If you’ve been asking yourself these question, we’ve got all the answers you need!

What Is Colloidal Silver?

For starters, let’s refresh some basic physics knowledge. Essentially, a colloid is a mixture made of a non-solid base substance (such as a gel, liquid, or foam) and some sort of insoluble particles suspended in it.

For instance, did you know that smoke is a colloid of ash suspended in the air? Likewise, milk is a colloid of butterfat in water.

Colloidal silver, in this case, amounts to microscopic particles of silver suspended in water or gel. The smaller the particles are, the safer and more effective the solution is, even in lower concentrations.

How Does Colloidal Silver Work?

First and foremost, silver is used as a powerful antiseptic agent thanks to its ability to kill all sorts of bacteria, viruses, and fungi (even some of the most dangerous ones). Here’s how it’s done:

Scientifically Confirmed Colloidal Silver Benefits

Effectively Treat Common Respiratory Infections

Did you know that common cold is caused by viral threats in over 80% of the cases? That’s why antibiotics are a terrible idea: they NEVER kill viruses, so taking them would mean just risking your health with all the possible side effects.

Silver, on the other hand, is a whole different story. It does a stupendous job in eliminating a whole lot of viral invaders, including those that cause common cold.

What’s even better is that silver is safe for treating children. In 2011, a study was conducted to check whether colloidal silver could help kids with common cold to get better, so the scientists divided the little patients into two groups: the first one received colloidal silver, the second one was treated with saline solution. Here are the results:

  • In the colloidal silver group, 90% of children recovered by the end of the treatment period. 10% developed infection-related complications like bronchitis, tracheitis, or otitis.
  • In the group that did not receive colloidal silver, 66% of children recovered and 34% developed complications.

How to use colloidal silver to treat common cold and similar respiratory infections:

Fill a clean dropper with your colloidal silver solution. Tilt your head backwards, put 3 to 5 drops of the solution into each nostril, and maintain this position for some 5-10 seconds. Repeat the procedure 3 times per day until symptoms subside.

Cure Sinusitis Without Antibiotics

Colloidal silver in form of nasal sprays shows outstanding healing properties in patients with chronic Staphylococcus aureus rhinosinusitis, a condition that’s quite resistant to conventional antibiotics. When the effect of colloidal silver was then put to a test in a controlled lab environment, it turned out that this natural wonder was able to kill over 98% of the bacteria.

How to use colloidal silver to treat sinusitis:

Just as described in the previous point, tilt your head and put up to 5 drops of colloidal silver into each nostril. If you’re using a colloidal silver spray, go with 2 squeezes into each nostril instead. Repeat 3 times per day until symptoms improve.

Fight Back Nasty Ear Infections

Colloidal silver is one of the most effective treatments for otitis externa (swimmer’s ear) and otitis media. In a sense, it’s much better than even the most powerful conventional drugs as it’s effective not only against bacteria but also kills possible viruses and fungi present in the area.

Without extensive lab testing it’s impossible to pinpoint the cause of one’s ear infection, so having all possible options covered with a single shot is absolutely a great idea.

How to use colloidal silver to treat ear infections:

First of all, warm up your silver solution to body temperature. Lie on your side (with the infected ear facing up) and carefully put 3 drops into the ear canal. Keep lying in this position for about 5 minutes, then let any excess liquid to flow out by either lying on your other side or by standing up and tilting your head in the opposite direction. Repeat the procedure 3 times per day.

Cure Eye Infections Faster Than Ever

The most common eye condition is known as “pink eye,” also known as conjunctivitis. Essentially, this is an inflammation of the inner lining of your eyelids and the eye’s visible surface.

Highly contagious and utterly annoying, this condition can be caused by a whole bunch of bacteria and viruses—and silver fights them all!

Just take into account that if you want to use colloidal silver to treat an eye infection, it is crucial that you use only true colloidal silver, otherwise you could develop local argyria—silver deposits on the conjunctiva. This effect isn’t dangerous in terms of health, but it’s irreversible and doesn’t look pretty at all.

So once again, and it’s important: Look for true colloidal silver, as fake or impure products could become a disaster for you. Keep reading to learn a simple hack on how to choose pure colloidal silver!

How to treat conjunctivitis (pink eye) with colloidal silver:

Assume a comfortable position (standing, sitting, or lying) and tilt your head backwards. Place your finger on the soft tissues directly under the lower eyelid and gently pull them down, thus forming a little “pocket” between the eyeball and the eyelid’s rim. While looking up, gently put 1-2 drops of colloidal silver into the conjunctival pocket, then let go of the lower eyelid and close your eye. Repeat 2-3 times per day.

Disinfect Wounds And Heal Them Faster

No matter which form of colloidal silver you choose to use (liquid, foam, gel), know that it can be safely applied to fresh injuries to inhibit the growth of up to 100% of the germs. Clean wounds heal SO MUCH faster!

How to use colloidal silver to treat fresh wounds:

If the wound is fresh, you can use the colloidal silver solution to rinse the injury and clean it from dirt. Alternatively, you can put 1-2 drops of colloidal silver on a Band-Aid and put the latter on the wound.

Treat Burns For Faster Healing

Before the invention of penicillin, silver has been one of the go-to approaches for treating burns. It was re-introduced only in the 1960s in the form of silver salts (namely silver nitrate) which proved to be effective antimicrobials but came along with a few drawbacks.

For instance, silver nitrate was quite toxic and significantly slowed down regenerative processes. Silver colloids, on the other hand, aren’t toxic and do not inhibit healing, so are absolutely a better option to go with.

How to use colloidal silver to treat burns:

Rinse the burn with colloidal silver solution, then apply a clean bandage soaked in colloidal silver. It is recommended to change the bandage at least twice per day, each time rinsing the wound with colloidal silver.

Support The Immune System

Last but not least, many people take colloidal silver orally to support the immune system. Scientific evidence on this matter is scarce, but the recommended dosage usually doesn’t exceed 1 full dropper (roughly 1 teaspoon) 2 times per day for up to 14 consecutive days.

How To Be Sure Your Colloidal Silver Is The Real Deal

The three most popular silver-containing products on the alternative healing market are:

  • Ionic silver solutions
  • Protein-bound silver solutions
  • True colloidal silver

Ionic silver is significantly weaker than colloidal silver but is very cheap to make and that’s why it’s still sold far and wide. Please, remember that ions are unstable and electrically active particles, so it’s hard to predict how they will interact with the cells of your body. It is recommended to stay away from ionic silver products.

Protein-bound silver solutions are colloids in which the silver particles are attached to protein molecules, then dispersed through water. The main problem with these products is that the present silver particles are quite large, meaning that each drop of the liquid is packed with a much higher dose of the metal than needed for it to impose its health benefits. As a result, protein-bound silver solutions can lead to the development of argyria or silver toxicity. This condition is irreversible.

True colloidal silver, on the other hand, consists of microscopic particles of pure silver suspended in the liquid base. Due to their tiny size and even distribution throughout the liquid, true colloidal silver is fairly safe to take and is believed to never cause argyria.

How can you be sure you’re taking true colloidal silver?

This is a safe brand that we trust and have received positive feedback: Sovereign Bio-Active Silver Hydrosol for Immune Support (10ppm).

Two Easy Steps To Prove True Colloidal Silver

Step 1:

Shine a beam of light through the liquid (a small laser or a flashlight should do the trick). If the liquid is a colloid (protein-bound silver or true colloid), the light will be visible due to the microscopic particles in the solution. This is known as the Tyndall effect, and this phenomenon is NOT seen with ionic silver solutions. Here’s how it looks like:

colloidal silver test

Step 2:

So, let’s say your solution has a positive Tyndall effect. Next step is to see whether the liquid is a protein-silver or a true silver colloid. To do so, shake the bottle of your product: protein-bound silver solutions produce a thick foam that can last for up to a couple of minutes. True silver colloid does not produce any consistent foam when shaken.

This two-step process is exceptionally important because true colloidal silver has virtually no side effects, but ionic silver and protein-bound silver can lead to argyria or silver toxicity.

Argyria is a condition characterized by the formation of silver deposits in the skin, mucous membranes, and inner organs. Argyria is thought to be mostly harmless yet utterly frustrating in terms of appearance—a blue-greyish toned skin color!

Rare sources affirm that argyria could be accompanied by a decrease in kidney function and worsening of night vision.

For safety reasons, most natural healing experts recommend abstaining from taking colloidal silver for no longer than 14 consecutive days orally. Topical application is usually considered to be absolutely safe.


It’s hard to think of a natural healing agent that’s more powerful and versatile than colloidal silver. It’s applied topically and taken orally, used to fight infections and heal wounds, support the immune system and eliminate nasty germs.

What’s also great is that this natural wonder is fairly affordable, so it’s not surprising that thousands of families around the world always keep a bottle or two in their homes.

Just make sure to ALWAYS go through the described two-step process above to make sure your colloidal silver is really pure, safe, and as effective as you’d expect it to be.
