SILVERLAB PRODUCTS Frequently Asked Questions

Can Silverlab ionicᐩ Colloidal Silver stain fabric or surfaces?
  • Some surfaces might be prone to staining; especially plastic based surfaces.
  • Some fabrics (especially white fabrics) might be prone to staining.
  • In terms of sanitising surfaces, always test a small, unnoticeable section of the surface that you want to spray in order to evaluate the risk for staining.
  • When using Colloidal Silver products, take caution not to drip or spill the liquid onto clothing or fabric.
  • When nebulising Colloidal Silver, make sure that the condensation on the face mask does not drip directly onto your clothes or sheets, but rather let it drip onto a cloth or towel.
  • How to remove stains: for white surfaces or white fabric, first use table salt and water (soak for 15-mins then rinse). Then  soak in diluted bleach for 10-mins, then rinse.
How much is too much Daily Immune Booster?

How much is too much of Silverlab Colloidal Silver?

When adults drink Silverlab Colloidal Silver Liquid (18 ppm), it is advisable to use up to 8 litres per year only.

This can be done every year for 70 years. That equates to 555 litres in your lifetime. So 556 litres may be too much. Source: World Health Organisation and FDA, EPA.

How much Daily Immune Booster Liquid is too much?

Even at the full dosage of drinking 555 litres, if a person notices any sign of argyria (a slight blue tint to the skin), he or she may stop using Silverlab Liquid and the condition will immediately stop progressing. The famous Paul Karison drank a large glass of homemade Colloidal Silver of unknown strength twice per day for 25-years. This was more than ten times the recommended dose (i.e. 320 ml x 2 x 365 x 25 years is 5 840 litres), and when he started turning blue he continued taking it. Why? Because he preferred the blue skin tinge to the severe eczema that plagued him. We believe that he did not exercise either wisdom or caution. He continued using it until he passed away from a condition unrelated to the eczema or the use of colloidal silver.

The above relates to an average person of 70 kg mass.

Is Colloidal Silver Safe?

Silverlab ionic colloidal silver has a favourable safety profile and can be taken internally and applied topically. It is a nontoxic, natural remedy that assists with the prevention and management of a number of health conditions.

Someone told me that our bodies cannot absorb colloidal silver. is this true?

There may be some generalized, superficial truth in that statement but it lacks depth.

All elements and minerals that pass into your system have to be carried. Your body has many enzymes for doing this. Did you know that 50% of your body’s enzymes are designed for carrying metals?

When taking colloidal silver it is important to hold it in your mouth for 2 minutes before swallowing. There are 2 reasons for doing this:

1. Homeopaths recognize that you get absorption of minerals, including ionic colloidal silver, directly into your bloodstream from the blood vessels under your tongue which are situated very close to the surface. We call this sub-lingual absorption.

2. The second, and probably more important aspect of holding the liquid in your mouth is so that your saliva can mix with the silver solution. Silver ions then bond onto the enzymes (amino-acids) in your saliva as per their design. This enzyme is now able to:

a. Pass through the acid barrier of your stomach without turning into silver chloride. (Silver chloride is a true colloid and has an efficacy of 1/10 of Silverlab ionic colloidal silver 18 ppm, great for reversing food poisoning).

b. Carry the silver ion through the wall of the gut and deliver it to the area needed in your body.

For food poisoning and tummy upsets you do not hold in mouth before swallowing. This allows the silver to pass through your entire gastrointestinal system, coming into contact with the bad bacteria and microbes, and killing them.

If it were true that ionic silver does not pass through the membranes, then why is it such an effective medicine? If colloidal silver doesn’t work, why is it the most popular alternative medicine on the planet?

The truth is that this is such a good product that it has become the preferred CAMS (complementary and alternative medicines) product for those who are serious about their health.

Use Silver with confidence for:

• Anti-inflammatory action

• Bacterial infections

• Anti-microbial

• Fungal infections

• Viral infections (not effective against all viruses)

• Immune booster

• Promoting faster healing

• Etc.

Is 10ppm Nanosilver better than Silverlab 18 ppm ionic colloidal silver?

A certain Dr Rima incorrectly states (October 2014) that 10ppm nano silver is better than 25ppm nano silver.

She is quoting from the USA Defense Threat Reduction Agency paper cleared for public release. 

The paper does not compare strength of silver (ppm) but the actual size of the particles (nm). It shows 10nm silver to be better than 25nm silver.

If you have read my Scientific Paper, you will be aware that there are many companies around the world trying to establish themselves as a preferred supplier of colloidal silver. They all seem to say “mine is better than yours”.

We have opted to not participate in this negative practice. We have conducted our own research using independent laboratories to establish facts around our products. One of these facts is that “Low concentrations of silver ions are antibacterial. (Ref. 1)”.

Another is that “Silverlab ionic silver, even when diluted 1:4 proves to be a very good anti-inflammatory (Ref. 25)”. Further research has also proved colloidal silver to be anti-viral. See what the experts say here.

When using Silverlab colloidal silver as a tonic it is important to heed the instructions on the bottle. “For best results hold in your mouth for 2 minutes before swallowing”.

This allows the enzymes (saliva) in your mouth to bond onto the silver ions to form a metallo-protein. This metallo-protein carries the silver through the acid barrier of your stomach into the intestines for absorption. They then continue carrying the silver through your body.

The silver in this form is sub-nano, i.e. it is much smaller than nanosilver. (The proponents of nanosilver say that the smaller the silver particle is, the better the product will work.)

So we have established that Silverlab colloidal silver is known to kill bad bacteria, fungus and even parasites and viruses. But now we  know that it is an anti-inflammatory too:

“ All sickness and disease has an inflammatory component. Taken as a tonic, Silverlab Liquid would help to normalize the body at a cellular level, allowing the immune system to operate more efficiently. It helps your body to heal itself.”

[Prof. Patrick Bouic, Synexa Life Sciences, July 2007]

If you are convinced that silver nano particles will assist you, you can be assured that Silverlab ionic colloidal silver will do exactly the same if held in the mouth for 2 minutes before swallowing.

10ml Colloidal Silver Liquid taken daily will assist your own body to fight off disease.

So, to answer the question: Silverlab is equivalent to, if not better than nanosilver and it has the added benefit of being stronger in concentration so lower doses can be administered to get the same effect.

What does colloidal mean?

Colloidal simply means a suspension of ultra–fine particles of one substance, suspended by an electric charge in another substance. With colloidal silver, ultra–fine particles of silver are suspended in distilled water.

Will colloidal silver kill good bacteria?

Absolutely not. Unlike prescription antibiotics it does not kill good bacteria. It has no known side effects reported to date, even in high doses.

Can I overdose on colloidal silver?

Adults should not ingest and/or inhale more than 550 litres of 18 ppm ionic+ colloidal silver in their lifetime, an average of 8 litres per year, to prevent the possibility of Argyria developing. Although this is rare and appears to be purely cosmetic, excessive use could result in the body being unable to efficiently excrete the silver, leading to deposits in the skin, internal organs and tissues. This may result in the skin becoming permanently discoloured a gray or blue-gray colour. There is no known effective treatment for it. Early signs of Argyria include discolouration of the membranes covering the eyes (conjunctival membranes), gums and on the nail beds, just above the moon of the nail. Should this occur, the use and/or intake of colloidal silver should be discontinued.

Can I take colloidal silver for my chronic disease?

Yes! Silverlab’s Colloidal Silver may assist with the management of chronic conditions through its dual anti-microbial and anti-inflammatory actions when taken daily.

Is there a connection between colloidal silver and quick silver?

No, there is NO connection between colloidal silver and quick silver. Quick silver is the common name for mercury and is very poisonous.

I've just started drinking colloidal silver, but feel worse. Why?

Due to the detoxification qualities of colloidal silver, symptoms may temporarily get worse as your body eliminates these toxins. Drink 1 to 2 litres of water for 2 days or until this passes in order to flush out the dead pathogens.

What is Argyria?

Argyria for Health Reboot Campaign

The condition known as Argyria is the only acknowledged effect of excessive intake of colloidal silver over long periods of time. Since inception (2000), Silverlab has never had one reported case of Argyria.

It is characterised as a very rare cosmetic problem, where the body is unable to efficiently excrete excessive amounts of silver, resulting in deposits in the skin tissue. This may result in the skin becoming a grey or blue-grey colour. No other associated adverse health effects or toxic reactions have been reported. 

The onset is gradual and can be detected early. Early signs of Argyria include discolouration of the conjunctival membranes, gums and on the nail beds, just above the moon of the nail. Should this occur, use of colloidal silver should be discontinued. 

According to reports from the World Health Organisation, EPA IRIS and the FDA, it requires an accumulation of more than 10 g of silver for Argyria to manifest. 

Ingestion and excretion: The EPA IRIS report assumes an oral retention factor of 0.04, which means 4 % of ingested silver is retained and 96 % is excreted. 

Safe dosage for Silverlab 18 ppm ionic+ Colloidal Silver: A person with an average weight of 70 kg can safely ingest and/or inhale 8 litres of Silverlab Liquid per year. This equates to 555 litres of Silverlab Liquid over a 70-year lifetime.  Most people do not ingest/inhale volumes of up to 8 litres of Silverlab Liquid year-on-year. This then allows for a high-dose intake protocol to safely be followed for periods of 3 to 4 months. The same applies to high-dose intake/inhalation during times of acute illness. The key is just to remain within the 555-litre limit per lifetime. 

Silverlab Healthcare has done extensive independent studies on the safety of their products, and can confidently conclude that the outcome of all the studies proves a favourable safety profile.

What are the characteristics of a good Colloidal Silver?

It must be manufactured in accordance with Good Manufacturing Practice (GMP) standards

Colloidal silver and the Ebola virus?

Fact # 1

Silverlab colloidal silver liquid has not been clinically tested against the Ebola virus. We do not claim that Silverlab cures Ebola.

Fact # 2

The Defense Threat Reduction Agency in American has released a document into public domain citing colloidal silver as a possible preventative and cure for the Ebola virus. Fore more information, click HERE.

Fact # 3

The paper shows that 10nm silver is better than 25nm silver. In other words, the smaller the particle, the better: Silverlab 18 ppm ionic colloidal silver  was not tested but the particles are smaller than 1 nanometer and would therefore be even better than the 10nm silver tested.
[A certain Dr Rima incorrectly states (October 2014) that 10ppm nano silver is better than 25ppm nano silver. The paper does not compare strength of silver (ppm) but the actual size of the particles (nm). It shows 10nm silver to be better than 25nm silver]

Fact # 4

Silverlab is a complimentary and alternative remedy (CAMS) designed to “assists those with self-diagnosed health conditions”. The South African Constitution allows us to self-medicate.

Fact # 5

South Africa is setting up emergency isolation wards across the country which will enable a person diagnosed with the Ebola virus to be treated. It is possible that untested drugs may be used by doctors.

Fact # 6

The paper mentioned  in #2 suggests that silver is only effective against the virus in the early stages of it’s development. For best results, it is better to start treatment before infection or within a very short time after infection. Prophylactic use is recommended.

Fact # 7

The author of this FAQ (Ian McQueen) and his entire family will immediately start taking Silverlab colloidal silver: 20ml, 4 times per day if there is an outbreak of Ebola in South Africa or if we believe we may have come in contact with it.

For best results hold the colloidal silver Liquid in the mouth for 2 minutes before swallowing. The silver ions will bond onto the enzymes in the saliva forming a metallo-protein. (50% of the enzymes are designed to carry metals around the body).

The metallo-protein carries the silver  ions through the acid barrier of the stomach (hydrochloric acid), carries it through the gut wall and then may help in delivery the site where it is needed.

For combatting acne from the outside, apply the liquid to the skin with a cotton pad.  Follow that up with applying our Healing Gel or Healing Cream after wiping the skin with the cotton pad. If you feel that you are struggling with an oily skin, go for the Healing Gel.  If you feel you are in need of an extra bit of moisture, go for the Healing Cream.

What Is Silver Repair™?

Some products contain a unique formulation of Silver Repair™, containing ionic colloidal silver with proven anti-inflammatory, antibacterial, antifungal and antiviral properties.

It is ideal for the prevention and management of various health conditions associated with the South African climate.

Some of these conditions include, but are not limited to: chafing, sunburn, dermatitis, eczema, dry and cracked skin, ear infection, jock itch, dry lips, scrapes, wounds, and blisters.

What is Jock Itch/Dhobis Itch?

Jock itch or Dhobis itch is a rash between the legs. It can also affect the skin around genitals, inner thighs, and buttocks. It is usually caused by the fungus Candida albicans. This is exacerbated by heat and sweating.

Cyclists and runners often suffer from this condition. It also is more likely to occur in people who are overweight.

The rash can present as being itchy, and often ring-shaped.

Although often uncomfortable and bothersome, jock itch usually isn’t serious. Keeping your groin area clean and dry and applying topical antifungal agents usually are sufficient to treat jock itch.

One such a great antifungal and non-toxic topical agent is the Silverlab Sport Chafing Repair Cream.

Silverlab Sport Chafing Repair Cream with Silver Repair™ is indicated for the prevention and management of jock itch/dhobis itch due to its antifungal properties. It is safe for use in the most sensitive areas.

What is the condition swimmer’s ear?

Swimmer’s ear affects the outer ear. It is a condition that usually occurs after water is trapped in the ear, leading to inflammation, irritation or infection.

Swimmer’s ear not only presents in swimmers, but can also affect those with eczema or excess earwax. It can even result from excessive cleaning of the ear canal, contact with chemicals such as hair spray, or contact with bacteria in hot tubs.

Symptoms can include itching inside the ear, slight fever, discharge from the ear, and pain, often severe throbbing that worsens when the earlobe is touched or pulled. Temporarily muffled hearing and/or a sensation that the ear is “blocked” may also present itself.

The formulated Ear Rescue with Silver Repair™ may relieve and prevent outer ear infection and Swimmer’s ear through its anti-inflammatory, anti-fungal and anti-bacterial properties and assists with the clearing of trapped water from the ear canal.
