Colloidal silver can be poisonous if swallowed. There is no evidence to suggest that silver retains the same antimicrobial qualities when internally ingested.
According to the Environmental Protection Agency, (EPA), most people have already been exposed to silver every single day.
In order to develop an argyria condition, it would be necessary to consume silver compounds over a lengthy period. But, it isn't clear how many and when you might be at risk (16).
This suggests that topical, short-term use of silver-containing items has its place in treatment.
The ingredient of some cosmetics and treatments for acne is colloidal-silver. It is also used in some eye drops formulas to prevent conjunctivitis from newborns.
You're at greatest risk of developing Argyria when you consume a silver-containing food supplement, or work in a position that requires you to ingest large quantities of silver.
Silver toxicity is rare but can occur over months and even years. According to research done by Imperial College London, this can lead to severe disfigurement, as well harmful deposits in your liver, spleen and kidneys.
Colloidal Silver is a great example of anecdotal research that is significantly different from scientific research. The FDA has not approved oral colloidal silver as a medical product.
Furthermore, if the silver buildup in the tissue surrounding an open wound is frequent, localized argyria may occur (18).
The human body does not require silver. It's not an indispensable mineral and serves no purpose in biology.
A dosing guide chart from the EPA states that your daily silver exposure, whether oral, topical or environmental, should not exceed 5 mg per kilogram.
The risk of ingesting colloidal sodium is lower than that of applying it to your skin. These nanoparticles can be absorbed by your skin (17).
A 2018 study by Iran found that topical ointments containing silver nanoparticles were able to reduce the skin's inflammation during healing, and speed up the skin's growth. This was in contrast to placebo.
Colloidal silver doesn't pose a risk to argyria if it is only used topically and in small quantities.
There are no known risks associated with ingesting nanoparticles. These may be found in colloidal Silver products.
This does not mean silver isn't good for your health. Colloidal silver can help prevent infection by being applied topically (on the skin).
It is not a mineral or vitamin that naturally occurs in the human body. There is no need to supplement your silver intake with any other vitamins or minerals.
Argyria, a condition in which the skin turns a dark blue-gray colour due to a buildup or silver metal particles within the body and skin, is called "Argyria". Silver deposits can also develop in the liver (16), intestines (16), kidneys (16), and other parts of the body (16).
There have been many studies that looked into the effectiveness of silver-containing dressings to treat skin wounds or ulcers. Many studies have demonstrated that silver particles are antibacterial and can help treat diabetic ulcers.
Most commonly, colloidal silver is sold in liquid tinctures. Most health food shops carry it. It can also come as a powder you can use on your skin. You can even make your own colloidal Silver at home with a special machine.
These particles are considered a health risk because they can more easily get into your cells and possibly cross over the blood-brain boundary.
