Colloidal Silver: Everything Parents Need To Know
What Is Colloidal Silver?
Colloidal silver is a medicine made of tiny silver particles and silver ions suspended in water. Silver has been used in medicine for centuries, and before the advent of antibiotics, silver was one of the most important and widely used antimicrobial remedies. It is still frequently used in burn care, water purification, food packaging, bandages, and wound dressings.
Silver is a trace mineral that is naturally occurring in some foods. Humans typically consume 27-88 micrograms of silver per day in their diets.
What Can Colloidal Silver Treat?
Colloidal silver is one of the most reliable antimicrobials in the natural medicine toolkit. It works for many different viruses, bacteria, molds, yeast, and fungal infections.
As an antiviral, silver can kill the virus that causes Covid-19 and may be an effective adjunctive treatment. There’s also evidence that it may be effective against other viruses of interest, including monkeypox, herpes, RSV, and viruses that cause upper respiratory tract infections (like influenza).
As an antibiotic, silver is effective against a wide range of bacteria including drug-resistant strains. It is also active against the strains of bacteria that cause or worsen ear infections, bronchitis, pneumonia, eye infections, and sinus infections.
As an antifungal, silver is effective against candida (the cause of yeast infections) and Trichophyton mentagrophytes, a major cause of fungal infections of the hair, skin, and nails. In one clinical trial, it was found to be as powerful as Amphotericin B, a powerful antifungal that is considered superior to the more commonly prescribed fluconazole.
Silver is also useful for healing wounds and for treating other skin conditions like acne, eczema, and psoriasis, especially if infection is present.
Silver is a possible treatment for peptic ulcers, allergic asthma, cancer, and cystic fibrosis. It may be an effective blood thinner, immunomodulator, anti-inflammatory, and antioxidant. It will be interesting to see how the research develops for these and other applications in the future.
How Do You Use Colloidal Silver?
Colloidal silver can be taken internally, applied externally, injected, or inhaled using a nebulizer. Dr. Green Mom Colloidal Silver was formulated for internal consumption and external application. It was not formulated to be inhaled or injected. Silver is effective at a very low dose. More is not better.
Follow the directions on the product label for internal dosage of colloidal silver when treating colds, cases of flu, or other infections. Dr. Green Mom Colloidal Silver tastes like water and is easy to give to even the pickiest kids.
For external application, silver can be used to clean wounds. Some moms like to purchase a spray top so that they can spray colloidal silver onto eczema, diaper rash, athlete’s foot, and other skin conditions.
Colloidal silver can be used to wet a cotton pad or washcloth to wipe sore infected eyelids. Dr. Green Mom Colloidal Silver was not formulated to be used directly in the eyes.
Colloidal silver is best taken on its own away from food, herbs, or other medications. It doesn’t interact with any natural or conventional medications, though it may interfere with the absorption of thyroid medications and certain antibiotics.
Some sources recommend taking colloidal silver daily as a preventative, immune booster, or overall health tonic. However, in my home and medical practice, I prefer to use silver for short periods to treat wounds and infections. Always consult a healthcare professional before taking colloidal silver.
How Does Colloidal Silver Compare To Herbal Medicine?
Colloidal silver works well for so many infections that it is easy to wonder if it can replace a whole medicine cabinet worth of remedies! This is partially true. When I am traveling, colloidal silver is often one of the only medicines that I pack and I trust it will help my family through most illnesses that could arise.
However, herbal medicine does much more than simply kill viruses, bacteria, and other disease-causing germs. A well-formulated herbal preparation can support the immune system, heal tissues, soothe symptoms, and provide nourishing strength. For example, Bronchial Calm contains antimicrobial herbs that soothe coughs and thin mucus, while Ear Relief & Resolve contains antimicrobial herbs that soothe pain.
When treating my patients and family, I usually rely on specific herbal medicines, and when necessary, boost the infection-fighting effects by adding colloidal silver.
Will Colloidal Silver Turn Me Blue?
The most frequent safety question regarding colloidal silver is: will it make me turn blue? Argyria is the name for the condition that causes people’s skin to turn slate-gray or blue after the excessive consumption of silver. Consuming larger particles of silver, silver salts, or silver proteins increases the chances of developing agyria as does excessive silver consumption over a long period of time.
While consuming any silver (even the small particles found in colloidal silver) could in theory cause Argyria, the dose of Dr. Green Mom’s Colloidal Silver that would be necessary to do so would likely be in the gallons. When used as directed colloidal silver is safe per the EPA (see below).
How Does Colloidal Silver Impact The Microbiome?
Because silver is a potent antimicrobial, it is important to consider the health of the microbiome while using it. Research shows that while silver is capable of killing both good and bad bacteria, it leaves the microbiome relatively undisturbed when taken for a short time (28 days or less). It is still unclear why a healthy microbiome is resistant to silver treatment, but researchers hypothesize that it is due to a complex interaction of the microbes, silver, and mucus membranes.
Can I Take Colloidal Silver When Pregnant Or Breastfeeding?
Silver passes through the placenta and into breast milk. As with many natural and conventional medications, there haven’t been any human studies assessing the safety of colloidal silver during pregnancy or breastfeeding. While I occasionally use colloidal silver use to fight infection for my pregnant and breastfeeding patients (based on historical use and clinical experience), it isn’t my first choice. Always discuss consumption of natural therapies, including colloidal silver, with your healthcare provider, especially when pregnancy or nursing. As an alternative: Mother’s Immunity Support is a mushroom-based immune support that was formulated specifically for use during pregnancy and breastfeeding.
Is Colloidal Silver Safe?
In my clinical experience, colloidal silver is quite safe when taken as directed. In high doses, silver can be toxic to some organ systems, as can many other metals that we consume including iron, zinc, and copper. As with all herbs, vitamins, minerals, and medications, following appropriate dosing is important for safety.
According to the EPA, colloidal silver is considered to be safe, even for sensitive populations, when taken long-term at a dose of 5 micrograms/kg/day. This works out to be 350 micrograms for a 150 lbs (70kg) adult. Dr. Green Mom Colloidal Silver contains 15 ppm of silver which is equivalent to 75 micrograms of silver per 5ml teaspoon.
Colloidal silver is an effective antimicrobial that can be helpful in treating bacterial, viral, and fungal infections. Colloidal silver is a potent medicine, so I don’t recommend taking it daily as an immune support, but rather think of it as a short term natural infection fighter.
