Preparations of silver have long been used in medicine topically for their antimicrobial properties — indeed, I’ve used them in my own practice. Silvadene cream is a commonly used topical medication to treat burn patients, and silver can be infused into bandages and dressings to aid in wound care and infection control.
But colloidal silver is a bit different; it consists of tiny particles of silver suspended in a liquid. Proponents of colloidal silver suggest that, when taken orally or used intravenously (IV), it can have immune-enhancing properties and combat a multitude of infections.
Prescription medications containing silver are effective, topical antimicrobial agents for burns and wounds with well-documented benefits. However, the problem occurs when you take colloidal silver orally or via IV. Although you may notice some systemic effects when you consume it or use it, your body can’t excrete it, so it builds up in your tissues like mercury and other metals.
Over time, people who ingest a lot of colloidal silver may start to notice a buildup in their fingernails, skin, or elsewhere, and there are many reports that people can’t get rid of it. Furthermore, IV colloidal silver use has been associated with anemia and low white blood cell counts. Those are significant risk factors to consider before using colloidal silver.
Generally, over-the-counter colloidal silver is relatively inexpensive compared to other supplements. However, IV colloidal silver can be quite pricey and isn’t covered by insurance. Additionally, research indicates the colloidal silver products you might purchase online don’t always contain the chemical constituents stated on the labels. In my opinion, we’ve got better alternatives to consider for Lyme treatment than using colloidal silver.
