Colloidal silver is a term you might have come across in conversations about natural remedies and alternative medicine. But what exactly is it? And more importantly, what is colloidal silver used for? This article dives into the world of colloidal silver, unravelling its uses, potential benefits, and controversies that surround it.

What is Colloidal Silver?

Colloidal silver is a solution consisting of tiny silver particles suspended in a liquid base. It’s essentially the same silver that you find on your periodic table or in your jewellery box, but instead of being used to make ornaments, this silver is often promoted as a health supplement or an alternative remedy for various health conditions.

The word “colloidal” refers to the particles of silver that remain suspended in the liquid rather than dissolving. The size of these silver particles varies, with some being so tiny that they’re referred to as nanoparticles. These are less than 100 nanometers in size and are invisible to the naked eye.

Historical Use of Silver

Silver’s use as a healing substance stretches back thousands of years. Ancient civilizations, from the Greeks to the Romans, used silver for its antimicrobial properties. They used it as a treatment for wounds, as an antimicrobial for food and water storage, and even claimed it could prevent the plague.

Fast forward to the 20th century, and silver-based medicines were common for treating various ailments. However, the discovery of effective antibiotics led to a decline in the use of silver as a primary treatment option. Nevertheless, colloidal silver has recently seen a resurgence in popularity as a natural remedy, with advocates claiming it can replace antibiotics or other medical therapies to treat bacterial, viral, and fungal infections.

Modern Uses of Colloidal Silver

In the modern context, colloidal silver is marketed as a solution for a wide range of health problems. From minor infections to serious diseases, proponents of colloidal silver claim that it’s a potent cure-all. Here are some of the common uses of colloidal silver:

Treating Sickness and Conditions

One of the primary uses of colloidal silver is in the treatment of various illnesses and conditions. Its antimicrobial properties make it a popular choice for those looking for a natural alternative to antibiotics. These properties mean that colloidal silver can potentially help fight off common bacteria and viruses responsible for sinus infections, pink eye, ear infections, pneumonia, shingles, and other ailments.

The beauty of colloidal silver, advocates say, is that, unlike antibiotics, bacteria will not develop resistance to it. This means that theoretically, bacteria will always be susceptible to its effects. But remember, these claims have not been officially endorsed by regulatory authorities like the FDA.

Skin Care

Colloidal silver also has a place in skincare. Its antibacterial properties can be beneficial when applied topically to wounds, cuts, and rashes. It can reduce inflammation and stimulate new cell growth, speeding up the healing process. It’s also useful for treating skin conditions like psoriasis and eczema.

Pet Care

Even our four-legged friends can supposedly benefit from colloidal silver. Some pet owners use it to treat various conditions in their pets, from colds to ear infections. However, as with human use, it’s crucial to consult with a veterinary professional before using colloidal silver on pets.

Is it Safe to Drink Colloidal Silver?

Now that we’ve looked at what colloidal silver is used for, the question that naturally arises is: Is it safe to drink colloidal silver? The answer, according to medical experts, is no. The U.S. Food and Drug Administration (FDA) has explicitly warned that colloidal silver is not safe or effective for treating any health condition. The agency has even taken action against companies selling the product with misleading health claims.

Ingesting colloidal silver can lead to a condition known as argyria, a bluish-grey discolouration of the skin that is usually permanent. It can also interfere with the absorption of certain medications, such as antibiotics and thyroid drugs.

Can You Put Colloidal Silver Directly on Skin?

While oral ingestion of colloidal silver is discouraged, applying it topically might be beneficial for certain conditions. Silver has been used in the past to treat wounds, and some modern dressings contain silver to aid in the healing process. However, it’s essential to consult with a healthcare provider before applying colloidal silver to the skin.

Does Colloidal Silver Actually Work?

The effectiveness of colloidal silver is a topic of debate within the medical community. While some studies have indicated potential benefits, especially regarding its antibacterial properties, these findings are often based on laboratory or animal studies. Human trials are limited, and the results are often inconclusive.

Moreover, regulatory authorities like the FDA have not endorsed colloidal silver’s effectiveness in treating any medical condition. Therefore, while anecdotal evidence may suggest certain benefits, it’s crucial to approach these claims with a healthy dose of scepticism.

Is Colloidal Silver an Antibiotic?

Colloidal silver is often touted as a natural antibiotic due to its antimicrobial properties. It’s believed to kill bacteria by damaging their cell membranes and interfering with their metabolic processes. However, unlike conventional antibiotics, colloidal silver is not selective in its action – it can potentially harm human cells as well.

What is the Difference Between Silver and Colloidal Silver?

Silver is a metallic element, commonly used in jewellery and various industrial applications. Colloidal silver, on the other hand, is a solution of tiny silver particles suspended in a liquid. The term “colloidal” refers to these suspended particles. It’s this suspension of silver particles that is used in alternative medicine and marketed as a health supplement.


In conclusion, while colloidal silver has a long history of use and is often promoted as a natural remedy for various health conditions, there’s a lack of robust scientific evidence to support these claims. Moreover, it can cause serious side effects, especially when taken orally. Therefore, it’s crucial to consult with a healthcare provider before using colloidal silver. As with any health supplement or alternative remedy, it’s essential to weigh the potential benefits against the risks.
