Colloidal Silver

Colloidal silver is a product made of tiny silver particles suspended in a liquid. It is typically sold over the counter in a liquid form for ingestion, as a nasal spray, or as a body spray.

What is silver?

Silver is a greyish-white metal that occurs naturally in the environment. It is used for making jewelry, silverware, electronic equipment, and dental fillings.

Medicinal uses of silver

Medicinal uses of silverHistorically, silver has been used for therapeutic purposes for centuries as a blood purifier, for offensive breath, for heart palpitations and for epilepsy.

In the late 19th century, pre-antibiotic, silver became popular as an anti-bacterial agent, being applied to wounds and burns to prevent infections, used in nose drops for the treatment of sinusitis and common-cold, and for the treatment of syphilis. 

Silver is still used in foil coverings for burn wounds and topical applications for ulcers, as well as in dressings on surgical incisions, and for coating of both temporary and permanent medical devices.

Colloidal silver itself lost some of its popularity in the 1930s and '40s, when antibiotics like penicillin came along; however, with increased resistance of bacteria to antibiotics, the interest in colloidal silver has risen again. From the 1990s it has been used for the treatment of ear infections, skin conditions such as tinea, eczema, psoriasis, and acne, as a throat gargle, and even as a natural support of immunity

How does colloidal silver work?

How does colloidal silver work?Silver is toxic to germs and has been shown to have the ability to destroy over 650 microorganisms including bacteria, fungus and even some viruses.

Colloidal silver does not attack bacteria directly but rather destroy the enzymes responsible for the reproduction and metabolism of microorganisms, killing them off very rapidly. This is why some researchers have called colloidal silver “a wonder antibiotic”.

Colloidal silver in Australia

Despite its antimicrobial properties, it is illegal in Australia to make any claims of therapeutic benefit for colloidal silver products. This is partly because there is not enough scientific evidence regarding their benefits, and partly because of the potential toxicity of colloidal silver.

Safety of colloidal silver

Long-term use of colloidal silver products can result in silver building up in the body’s tissues and organs, including the skin, liver, spleen, kidney, cornea, and muscle tissues.

Safety of colloidal silverThis can lead to an irreversible condition called argyria, a bluish-grey discolouration of the skin, especially in skin areas exposed to the sun such as the face, neck, and arms. The discolouration may also appear in the eyes, internal organs, nails and gums. 

The condition is rare and is not thought to cause any serious health problems other than the cosmetic appearance; however, once the silver is deposited, there is no way of getting it out.

The use of excessive amounts of colloidal silver can have an impact on the central nervous system and have been shown to cause kidney damage and seizures.

If you decide to use colloidal silver topically for short time and in small amounts, you will probably not turn blue. The National Center for Complementary and Integrative Health (part of the American Government’s agency for scientific research) suggests that it can be used in bandages and dressings to treat burns, skin wounds, or skin infections, but warns that colloidal silver should not be taken by mouth.

Do not use of colloidal silver if:

  • You are taking antibiotics or thyroxin. Colloidal silver may interact with the medications and prevent them from working effectively. 
  • You are pregnant or breast-feeding. There is not enough evidence regarding the safety of colloidal silver in pregnancy or when breast-feeding.  Australia’s best online discount chemist
