What Exactly Is Colloidal Silver? 

It really is silver—”colloid” is a chemistry term, describing a mixture of particles dispersed or suspended in another substance. The silver particles can range in size, but most are considered nanoparticles, less than 100 nanometers in diameter. You’ll find colloidal silver in liquid forms, usually in a base of purified or deionized water, or in topical first-aid gels or ointments. 

What Is It Used For?

Colloidal silver is really nothing new—silver itself has a long history of use in both conventional and alternative medical fields. It was routinely used to treat infections in ancient civilizations, with the earliest recorded use dating back to around 1500. During the Middle Ages, wealthy families used silver so frequently that they developed bluish skin discolorations—thought to have led to the term “blue blood.” 

In Western medicine, silver was first used in 1891 by a surgeon to sterilize wounds, and was widely used to treat infections until the 1940s, when antibiotics were developed. Even now, modern medicine routinely uses medical-grade forms of silver to treat burns, topical infections or wounds by killing or preventing the growth of bacteria. Until recently, it was also used to prevent conjunctivitis (pink eye) in newborns.

Does It Work?

Study results are mixed; some demonstrate the anti-inflammatory actions of colloidal silver, suggest it can kill a variety of bacteria and viral compounds, and support its use as a broad-spectrum antimicrobial agent. But results are mixed, and colloidal silver as an antibacterial or antiviral agent hasn’t been thoroughly tested in humans. Anecdotally, however, colloidal silver is the go-to immune health remedy for many people. I have repeatedly seen nanoparticle silver knock out viral infections in the early stage,” says Jeanette Ryan, DC, IFMCP, a functional medicine doctor based in Santa Monica, Calif.
