The use of colloidal silver can not cure cancer, AIDS or diabetes. Too much colloidal silver can cause skin discoloration, seizures and kidney damage.
A 2018 study from Iran concluded that a topical ointment containing silver nanoparticles was able to reduce skin inflammation during healing and speed the regrowth of skin compared to people provided a placebo.
As long as colloidal silver is used topically and in small amounts, it doesn’t pose a great risk of argyria.
Silver can cause skin to turn gray-black or bluish-gray over time if taken long-term. It can also cause seizures or kidney damage. Colloid silver can cause harm to the foetus and should be avoided by pregnant women.
Ultimately, the human body has no need for silver. It is not an essential mineral and serves no biological function of any sort.
Colloidal silver is also claimed to promote healing of skin wounds. According to a 2007 study, silver-containing wound dressings are a more effective barrier against infection than other products that make similar claims.
Colloidal silver is a suspension made up of small silver particles suspended in a liquid. Silver compounds can be used externally to treat or prevent infections. However, colloidal silver has been popularized as an alternative medicine. Although it is promoted as a treatment for diabetes and cancer, there is no evidence that it works in humans. Silver is not necessary for normal body function. The denatured proteins caused by silver can cause many enzymes to lose their effectiveness.
Many of these claims have been supported by test tube studies in which colloidal silver has been shown to exert powerful antibacterial, antiviral, antifungal, and anti-inflammatory effects. What the studies fail to show is what happens outside of the test tube.
The Environmental Protection Agency (EPA) estimates that most people are already exposed to silver every day in their environment.
Colloidal silver is made up of silver particles suspended within a liquid. This is often made by homemade generators. Silver medicinals were used to treat conditions such as epilepsy, gonadotrophia, and colds until the middle of the 20th century. In recent years, safer treatments have replaced silver. It is not considered an essential mineral and has no physiological function. It can denature proteins by binding to their reactive group and inactivate enzymes by forming the hemisilver sulfur sulfides with the enzymes' sulfhydryl chains (1).
A number of studies have investigated the use of silver-containing dressings on skin ulcers and wounds. Many of these have found that the silver particles exerted antibacterial properties that aid the treatment of diabetic ulcers, skin grafts, bed sores, necrotizing fasciitis, and other serious skin injuries.
Colloidal silver is an ingredient in some acne treatments and cosmetics. It’s also sometimes used in an eye drop formula to prevent conjunctivitis in newborns.
One small study found no benefits to a colloidal-silver nasal spray for treating chronic, recalcitrant rhinosinusitis. While silver compounds can still be used externally as antiseptics in preparations, there is a growing interest to use the colloidal form orally as an alternative medicine. Although in vitro studies have shown anti-tumor effects (8), there are no human data to support oral colloidal. Despite the lack of evidence, oral colloidal silver is being promoted as a treatment for AIDS, cancer, diabetes, and other diseases. Silver deposition can occur in the skin and mucous membranes over time, leading to irreversible conditions such as argyria. This condition is characterized by bluish-gray-gray-black pigmentation. Other adverse effects include seizures (6). Coloidal silver can cause developmental abnormalities in the foetus and should be avoided by pregnant women (1).
While silver toxicity is rare, silver can accumulate in the body over months and years. This can lead to severe disfigurement and potentially harmful deposits in the liver, spleen, kidney, muscle, and brain, according to research from Imperial College in London.
Colloidal silver’s most common commercial form is as a liquid tincture. Most health food stores carry it. It can also be bought as a powder to apply to your skin. Some people even make their own colloidal silver at home, using a special machine.
In suspension, silver is inelastic and can bind with proteins. Silver compounds can form hemisilver sulfuric sulfides that contain sulfhydryl group, which inactivates enzymes. The ability of silver to bind amino and carboxyl, as well as phosphate, and imidazole group (1) is also possible. Research has shown that silver can accumulate in the liver of rats and binds to various tissues and basal membranes. It can also alter the activities of glutathione peroxidase, lactate dehydrogenase, and the peroxidation membrane lipids.
When ingested, colloidal silver has the potential to cause toxicity and, in rare cases, death. Moreover, there remains little evidence that silver exerts the same antimicrobial properties when internalized.
A dosing reference chart created by the EPA suggests that your daily silver exposure — topical, oral, or environmental — shouldn’t exceed 5 micrograms per every kilogram you weigh.
The U.S. Food and Drug Administration warned colloidal silver companies that they were marketing false claims about their products helping to prevent or treat the coronavirus disease COVID-19 (15).
That is not to say that silver offers no health benefits. When used topically (on the skin), colloidal silver can aid in healing and prevent infection.
Silver isn’t a vitamin or mineral that naturally occurs in the body. You don’t need to make sure you’re getting an adequate dose of silver or do anything to make up for not being exposed to it.
