Not Just For Pathogens: Colloidal Silver May Have Antitumor Properties

December 14, 2010

Recently published in the Journal of Experimental & Clinical Cancer Research, “Antitumor activity of colloidal silver on MCF-7 human breast cancer cells” is great hope on two fronts: 1) the medical establishment is increasingly starting to tap the benefits of side-effect free colloidal silver, and 2) hard to treat diseases and their expensive, side-effect laden treatments may become things of the past.

Colloidal silver, which is well known for being a natural antibiotic, antiviral, and antifungal agent, as well as for it’s effectiveness in healing wounds like burns, has rarely before been tested for antitumor properties.

An in-vitro test by the researchers Franco-Molina et al. found that the right concentration of colloidal silver for LD100 (meaning all the cancer cells died) was 14ng/mL. The colloidal silver did not kill the PBMC (Peripheral blood mononuclear cells, or, in other words, cells belonging to the immune system).

The researchers concluded that “colloidal silver might be a potential alternative agent for human breast cancer therapy”. This is the very beginning of research, only one type of breast cancer having been tested, and it will take years before human testing begins, much less before it’s approved for mass use. However, given the lack of side effects from colloidal silver use, one hopes that the process will be expedited (most drugs are set back when the side effects are shown to outweigh the benefit).

Colloidal silver is frequently criticized as not being “safe or effective”, numerous studies such as this show that it is probably both, and over the hundreds of years that colloidal silver was used before the discovery of modern antibiotics no negative side effects have been discovered. Argyria is a possible side effect, but is strictly cosmological, and has only been reported with home generators and low-quality colloidal silver knock-offs.

Are you optimistic that this will be a breakthrough in the treatment of cancer?

There is no mercury in colloidal silver. Colloidal silver is made up of nanometer size pure silver particles that are suspended in pure water. Anything containing anything else is NOT colloidal silver.

Further, there are different things out there under the name “colloidal silver”: powder you can buy in a packet and mix in water, as well as generators you can buy and “make” colloidal silver. The silver in these products (the packet kind may contain other things, too) is a MUCH larger particle size that can more easily accumulate in the body.

There’s also another “colloidal silver” out there that is actually ionized silver. Ionized means that the particles have a charge, and that they will bond and form molecules as soon as they meet other charged atoms/molecules, meaning that they don’t do anything for you because they don’t stay pure silver.

Just do a little research about whatever you buy- true colloidal silver is nothing more than small silver particles suspended in water, and the best brands have very few ionized silver particles (it’s more complicated/expensive to make uncharged particles and remove ionized ones, which is why so many people sell ionized silver). Be wary of any product that claims it “has to be kept in glass”, this is one sign that it may be ionized silver, or something else.

It’s required that the contents of dietary supplements be clearly labeled, so if you’re still worried about Mercury, just check the label, and make sure they’re a reputable seller-check customer feedback, the Better Business Bureau page, etc.-here’s a link to Colloids for Life’s BBB page:

I hope all that helps you, please let me know if I can clarify or help in some other way. If you still have questions about the differences between different colloidal silver brands, these articles provide more detail:

Great news. Good to hear that research is being don. A question. The news said that there is mercury is in all silver. Is this true. So, would there be any in colodial silver. My husband stopped using it.
