Research◇3. Colloidal Silver. Part 2.

On September 5, 2022, my husband and I leaving for Eastern Europe for a 3-month hiking trip through Croatia, Montenegro and Albania. We want to hike their side of the Alps. Once again, we are going to carry everything on our backs. For this reason I want to minimize the things containing Colloidal Silver I pack. In my previous post Research◇2. Colloidal Silver. Part 1. I already explained that I took Silver Lozenges, soap and gel with me on our Mexico trip. This time I am planning to taking even less. Can I improve on my health supporting products without sacrificing the strength?Is it possible to take a very concentrated silver solution that can be used internally and externally? Let’s find out. This is the result of my research.

How Dangerous is Colloidal Silver?

There are many benefits of Colloidal Silver. Let’s explore the side-effects first. The Internet is full of warning against use of silver. The most easiest and cheapest way to make it is to run electricity through water with a chunk of solid silver in it. This way, you get water filled with positively charged silver ions. The bactericidal and antiseptic effect of silver ions on skin was scientifically proven. However, it is toxic for prolonged use, causing a permanent bluish-gray discoloration of the skin (argyria) or eyes (argyrosis), toxic effects, like liver and kidney damage, irritation of the eyes, skin, respiratory, and intestinal tract, and changes in blood cells. Yuck! This alone whats me to stop this research and throw away all the products I own with Colloidal Silver.

But then I discover silver nanoparticles – neutral coated silver particles that are stable and incredibly small. A Potent antiviral effect of silver nanoparticles on SARS-CoV-2 study concludes that silver nanoparticles( size:10 nm) damaged virus at concentrations ranging between 10 and 100 ppm. Yet another study Anti-tumor activity of colloidal silver on MCF-7 human breast cancer cells suggests that colloidal silver might be a potential alternative agent for human breast cancer therapy. Yet another, Efficacy of silver nanoparticles against the adults and eggs of monogenean parasites of fish reports damage observed to adult parasites and eggs, which are tolerant to any anti-parasite drugs we have to date. Well, nanoparticles look promising. What is the damage here? Based on the studies, coated silver nanoparticles have been demonstrated to be the least damaging even at 50 ppm in mammalian cells.

It looks like there is more than one kind of liquid silver solutions. And some kinds could be more toxic than others. Currently, there are 30+ brands selling silver solutions on Amazon. How can I find the right one?

Ingredients, Anyone?

If you look at the ingredients, most of them list only distilled water and silver. However, the color of silver liquids vary dramatically for different manufacturers from transparent to golden yellow, brown, tan or gray. How can that be?

First, there seems to be 3 types of PURE silver solution: Protein, Ionic, and True Colloidal. And then, there are infinite combinations of them in different proportions. Even food coloring can be thrown in to fake the appearance and rise the product’s concentration measurement. One reviewer questioned if the silver solution he bought was diluted by vitamin B. And, the ingredient label does not list it, or any others, because by FDA regulations companies does not have to list an ingredient if it is just under the certain amount. On top of it, no regulations or quality control is enforced on the production. That is is the huge problem as no-one can verify if the product is even real.

How Strong is the Concentration?

The manufactures print silver concentration in Parts Per Million of 99.9% Pure Silver on the packaging and nutritional labels. When looking at the concentration that is stated on the bottle, 10 ppm is a weaker solution than 30 ppm. The higher concentration solution like 1000 ppm are supposed to be used by literally drops or dissolved in water to make weaker solutions.

Going through the reviews I noticed that some customers have special meters that can measure the concentration. (Some even went farther and bought kits and produce the silver water solution themselves.) I am going to state all customers’ readings for any product I read reviews on. In general, I have found that the manufacturers’ stated levels of concentration to be on average twice as higher than the actual, and different batches of the product vary significantly.

A 50 ppm is the recommended serving.

Is it a Protein Silver?

Disclaimer: This guide the result of my personal research from information available to anyone on Amazon online store only. I did not communicate directly with any of the brand included, nor tested their products’ chemical qualities. I might be wrong about any brand, the type of protein they produce and its quality.

The easiest to spot is the Protein Silver.

Sometimes, a company puts the protein officially on the list, like Ultra Silver®. While trying the make higher concentration solutions silver molecules start to join together forming larger particles. Protein (possibly gelatin or glycerine) coats the separate molecules, preventing them from conglomeration. Ultra Silver®’s protein helps to stabilize the silver in the insanely high concentrations of 10,000 ppm. However, the protein also adds up to the ppm reading, making it impossible to know the true silver concentrate in the product.

Silver molecules, covered in protein, might be less effective. They might be a cause of sudden allergy, as one customer claimed for Ultra Silver® product. A silver protein is the one type that can also result in argyria, a permanent skin condition from the silver build up.

The first give away that the solution might have protein-coated-silver is brown color. But to know for sure, you can use a shake test. If after a few shales the solution develops foam, it has protein.

Here are some that I spotted right away:

Ultra Silver®
Supposed: 500 ppm
Actual: 30 ppm, 60 ppm, 66 ppm, 76 ppm and 100 ppm.

Brands With Protein Silver

Is it Ionic Silver?

Ionic Silver is produced by electrolysis when one electron was taking away from each Silver Atom, making the atoms become positively charged and repeal each other. That makes a stable but short lived solution. As soon as such atoms get into human digestive system they easily form salts and loose their effectiveness of killing any virus. The best chance Ionic Silver got to be effective is during topical applications.

To know if it Ionic, you can use a salt test. If after adding a sprinkle of salt to the solution, it becomes cloudy, it contains Ionic Silver.

The color of Ionic silver solution can range from clear to tint of color, yellow or even brown depending on the quality of the water used and time spent in electrolysis process.

Is it True Colloidal Silver?

Colloidal Silver solution contains Neutral Silver Particles. The most important factor while choosing the solution is the size of its silver particles, with the extremely small being the best. The effectiveness of this type of silver comes from its contact with biomaterial. Silver connects to some receptors, breaking cells/organism communications. Smaller particles have a higher damaging potential. They can damage some types of mammalian cells as well. Some silver manufacturers on Amazon claim that their product is safe and even probiotic friendly if you follow the recommended serving size. I think, it is a good idea to take probiotics a few hours after taking silver.

Each solver solution contains some limited amount of silver. If the amount of the silver is the same, what is better: the large number of smaller particles or the small number of large particles? The product with the large number of smallest particles has better chances of silver contact with a virus or a bacteria or a cancer cell. It also reduces the size of the damage to our healthy cells. On the other hand, if the silver particles are to scarce and too big, they can make people sick while reducing the chance of coming into contact with a virus! So, the correct silver size particle is the key to be the safest and the most effective when taken internally. To be truly labeled a colloidal the solution must have particles ranging at or below 9 nm, as anything larger than 9nm cannot pass through the nuclear membranes pores. Also, skin and mucosal membranes posses a real challenge for nanoparticles to get through, as they highjack transportation of any foreign materials.

True Colloidal Silver solution is clear with no color. Imagine tiny shiny reflective silver particles flowing in the water. You won’t see any color, but may notice extra shines. Any color tint indicates either it is contaminated with other substances to falsely inflate ppm measuring.

Is it a Combination?

Most manufacturers sell the combination on Ionic and Colloidal. Some manufacturers display their third party lab test results that specify the proportions. For example, SilverGuard disclaim it solutions to by 40% Ionic and 60% Neutral.

Will it Feminize Marijuana Plants?

Yes! I found it to be an interesting indicator of potent Colloidal Silver Solution. Here is the list of product whose reviews mentioned someone’s attempted to feminizing his plants and was unsuccessful.

Brands That Failed to Affect Plants

My Way to Rate the Brands

Finally, after removing obvious brands that might not be True Colloidal, I made a list of what is left. Even with some weeding out done, I still got plenty of brands selling silver liquids on amazon online store. Now, I needed some measurable way of organizing the silver solutions. So, I chose the measure of Price I Pay for Serving and organized the table from the cheapest to the most expensive.

And, here is how I came up with the measuring formula. Every product with silver in it, contains certain amount of total dissolved silver. Total Silver amount can be calculated as the Size (ml) x PPM of 1ml. For example,

Trinity NutraLab‘s Total Silver in one 32oz bottle is 245,960parts (946ml x 260ppm), while

Silver Doc‘s Total Silver in one 32oz bottle is only 18,920parts (946ml x 20ppm).

In addition, both products are priced differently.

Trinity NutraLab‘s 245,960parts costs $32.81, making the Price of 1part =$0.0001334 ($32.81 / 24,5960ppm), while

Silver Doc‘s 18,920ppm costs $27.99, making the Price of 1part =$0.00148 ($27.99 / 18,920ppm).

I could stop here and it would be a good measurement, but, instead, I decide that it would be fun to see how much I would pay not for 1 part but for a recommended serving (single use with the strength of 50 ppm). So,

Trinity NutraLab‘s Price of one Serving would come to $0.00667 ($0.0001334×50), while

Silver Doc‘s Price of one Serving would come to $0.074 ($0.00148×50).

I understand that my formula to rate the brands might not be be best indicator for the quality of actual products, as I am not aware of the true differences in its silver manufacturing and can only work with the numbers that the brands officially released through their product info. However, based on the numbers, here is what I got.

Testing Phase

Now, I ordered the #2 from my list – Guardian Of Eden 120ppm – for its price per serving and crazy concentration of 240parts for 1 ml. This way, I hope, I can bring the small amount of liquid with me that gives one of the highest concentration of silver available on the market.

I also tried it out. I put it directly on my face and hands twice a day for a week now. I was a little worried about the high concentration of silver and was afraid my skin cells will be damaged. I felt a light tingling sensation. It gave my skin a drying out effect. That was it! I will use it with moisturizer.

The label says to dilute it for internal use. So, I diluted it to use in my eyes. Even when diluted, my eyes could feet that it is not simply water. The solution has some thickness to it, even though it looks like water. I also was drinking some in the morning and at night for a week now. There is almost no taste to it. My throat felt a little bit dry afterwards. So, a sucking on a spoon of honey should fix the dryness.

I will keep testing it and update the blog!

Research◇2. Colloidal Silver. Part 1.

On October 6, 2021, right in the middle of pandemic, when many countries had to close their borders to visitors, my husband, my mom and I flew to Mexico City for a 6 month winter season. We came with only a backpack each and were planning on actively exploring the country. During these month we never rented a car, instead we used public transportation: flew locally twice (Leon -> Cancun and Cancun -> Oaxaca), took many taxis, subway rides and countless local and inter-cities busses. In this post, you will find the list of health supporting products that we took with us and that we bought in Mexico.

Last year, while researching on what ONE small face care product to take with me on our 6 month trip to Mexico, I accidentally stumble upon Colloidal Silver products. It seems like countless companies on Amazon online store are selling Silver gels and Silver liquids. They claim that Colloidal Silver products are made with 99.99% pure silver and are responsible for boosting immunity support, helping heal skin cuts and prevent getting sick. So, while going through reviews, I found the benefits that people bragged about.

Benefits of Colloidal Silver

  • safe – it can be used on kids and pets!
  • anti-viral – heals starting and advanced flu, cold, sore throat and upset stomach!
  • anti-bacterial and a substitute for antibiotic – heals skin cuts and burns, tooth abscesses, gum infection, pink eye, Strep, ears infections!
  • anti-fungal – clear blemishes, acne, warts, bad yeast skin infection in pets!
  • cures shingles rash!
  • speeds recovery time and healing!
  • can be used for cleaning and disinfecting purposes of surfaces (computers, toothbrushes and more) and clothes!

but the most surprising were

  • prescribed by a doctor to treat Lyme Disease, apparently, with success,
  • to feminize marijuana plants, and
  • to preserve cow milk for a few more weeks after the expiration date! This particular benefit, first, came from someone’s grandma who used to put silver coins in her milk for freshness. Today, the family keeps the tradition by adding a tablespoon of Colloidal Silver to one gallon of milk.

People found so many benefits to the Colloidal Silver. It sounds too good to be true, right? I read through so many reviews of true believers who claim that with this Heals-All-Solution our health care system will go out of business!

I also found out that topical EXTERNAL Colloidal Silver application on skin wounds don’t cause harm – they either improved or did nothing to correct the problem. However, some people reported plenty of side effects for taking it INTERNALLY, which attributes to the way of how the solutions are currently being manufactured. Here are just a few:

Possible Side Effects of Colloidal Silver

  • it interacts negatively with several common medications: not to be taken when you are on thyroid medication!
  • skin breaks out in very itchy hives – this one looks like allergic reaction to added protein used by some companies to bind the silver particles.
  • turns skin blue!

To see the full list, as well as my product research of Colloidal Silver liquids available on amazon, check out my next post Research◇3. Colloidal Silver. Part 2.

What I Took to Mexico

Well, I bought into the hype and decided to ordered some items to take with us to Mexico. I got

  • 3 bags of Silver Lozenges, any brand. They all seems to be working well and are made the same way. I figured that if I cannot bring much liquid on the plane in my carry on, then the Silver Cough drops are close enough alternative. We used them while flying or taking long bus rides. They worked, as we didn’t get Covid and we never got sick. Once in our journey, we came close to getting a cold, but taking the Silver Cough drops for a few days before going to bed stopped it dead in its tracks. Since we had only 3 bags, we kept them for special occasions only, meanwhile relying on the very good local cough drops (see below).
  • 1 bar of Soap by Silver Miracles. Again, to minimize the liquid, I ordered a soap that the manufacturer claims to be for body and face, unscented, uncolored, gentle enough for a baby, and great for shaving too. Of course, there are plenty of soap in Mexico, not with silver though. I used this one for soaping my face, ears and inside my nose every morning and leaving it on for hours while we visited markets and other tight places full of people.
  • 1 – 3.4 oz Colloidal Silver Gel by Institut Katharos. I picked it based on size of the bottle. Again, the airport security regulations limit the size of the container with liquid. I wasn’t very impressed by the gel. We used it on skin cuts, bug bites and I used it on my face for acne.

That is all we took with us!

Since our return from Mexico I ordered and tested the following topical EXTERNAL gels: ACS200 (200 ppm) by Results RNA, Sovereign Silver First Aid Gel (10ppm), Super Silver (45ppm) by Bodycare, for face acne and skin cuts with some limited results. Nothing I tried proved to be a game changer, however ACS200 by Results RNA won my daughter’s heart. She uses it in combination with other acne fighting products and claims that it is working.

What We Bought in Mexico

We didn’t get sick in Mexico, not with Covid, not with flu or cold. Besides occasional use of Silver Lozenges, my mom enjoyed Bicoestol Cough Drops (or Pastillas) with Eucalyptus by Mexican brand Broncolin for her chronic cough. You can find them at any pharmacy. The best price we got was in Mega Store. They sell it by jars.

We also bough some vitamins by Solanum. We took Platinum 50+ Vitamins And Minerals and Col-Q10 Colageno, which can be found in some Chedraui Super Stores. The were impressed by the combination of the minerals and vitamins for the price and fun jewel-like shells.

That is it! We also had so many fresh fruits and veggies!

Stay safe! Stay healthy! Travel light!

Mexico City◇5. Tenochtitlán

Let’s play! Today will will explore who the Aztec were and how, in 1325, they founded a city in a most unusual place that, by 1500, became one of the largest and most beautiful city in the world.

As you probably remember from my last post about the pilgrimage, that it took Aztec roughly 50 years after their arrival into the Valley of Mexico, to settle. It is possible, that the tribes controlling the valley, were not excited about sharing the land with new arrivals. That might explain why the only available lands were the islands. However dim the Aztec situation looked at the time, the not-so-desirable location turned out to be a blessing.

The first rule of survival is sustainable food production. Aztec caught fish and duck, but the island wasn’t big enough to support agriculture of corn, beans, amaranth, squash, chili or chia. They had to figure out how to grow food on water. And they did! Could it be due to their fish-rich diet?

Aztec came up with an idea of floating gardens. First, you weave a mat out of reeds, which are plenty, then you anchor the mat with a fresh tree branch from a willow tree, which are plenty, to prevent the mat from drifting away, and, last, you scoop mud from the bottom of the lake, thanks for the shallow lake Texcoco, onto the mat and plant seeds in it.

This technique ended up to be revolutionary, giving many advantages over growing on land. The first one Aztec experienced right away. With the mats floating on top of the water, you never have to water the plants, as their roots are always within water reach. This along removed dependance on rain, allowing the farmers to collect very high crop yields with up to four crops a year. Aztec never had to experience soil depletion as many different plants shared the same lake water that served as a good fertilizer. But wait, there is more! With time even willow tree branches that were holding the mats took root, turning the floating gardens into the floating islands. That is when Aztec realized that they could shape the land in any way they desired. It must felt pure magic to them.

Quest #1: Visits the World Heritage Site of Xochimilco. This network of canals is part of a 400-acre ecological park what remains of the lake, boats, and floating gardens of the ancient Tenochtitlán. Xochimilco's farms still farm the old way.

With food crisis avoided and new technique to “grow” the land, Aztec set about building their city. It was a matter of time when Aztec became the wealthiest tribe in the valley with lots of time on their hands for building what would become the largest and most beautiful city in the world.

The city was thoughtfully built with a symmetry. All constructions had to be approved by the city planning committee.

Three wide causeways or raised roads connected the island to the mainland in the north, south, and west directions. For strategical purposes (Aztecs already made enemies, remember the last post?) the causeways were interrupted by bridges (simple wood planks, really) that were removed at night. The bridges also allowed canoes to pass freely.

Two aqueducts were built, each more than 4 km (2.5 mi) long, to provided the city with fresh water from Chapultepec water spring.

The city had about 45 public buildings, temples, and palaces. The largest ceremonial center was at the Great Temple, dedicated to the gods of war and rain. There were also the temple of the Serpent, the Sun Temple and some minor temples, a ball game court, a platform for the gladiatorial sacrifice, a zoo, a botanical garden, schools, museums, public parks, a library, markets. Willow trees that anchored the island and more trees planted on top of buildings, provided great protection from sun, creating a microclimate of a lush and cool oasis.

In 1519, when Spanish Conquistadors saw Tenochtitlán for the first time, the city struck awe with them. Here is how it is described by one of the solder under Cortes command.

“… we were amazed and said that it was like the enchantments… on account of the great towers and cues and buildings rising from the water, and all built of masonry. And some of our soldiers even asked whether the things that we saw were not a dream?…

Quest #2: The last Aztec emperor Montezuma II 's Palace stood where is now the National Palace (Free). Visit the building in search for Diego Rivera Murals (painted between 1929 and 1951). Can you find the one of the Great Tenochtitlán?

Besides being the most unusual city in the world, it was also one of the largest, with estimation of more than 250 thousand inhabitants in 1519, and the population of the Valley of Mexico is estimated to be about one million. In comparison, at that time London had population of 50 thousand inhabitants, Paris – 185 thousands, Constantinople – 200 thousands, Beijing – 672 thousands. Today, after 500 years of challenging history, Mexico City again is among the largest. In 2020, Greater Mexico City was rated the 6th largest metropolitan area in the world.
