For more than a hundred years, colloidal silver has been promoted as an elixir that cures it all, and for more than a hundred years, people have been spending their money uselessly on it without any documented benefit.
No. Don't kid yourself. Colloidal Silver is basically a liquid suspension of silver. The only thing it has been proven to do is disinfect water, but nothing else. I do not recommend drinking colloidal silver because too much of it can cause a bluish or grayish discoloration of your skin. The website that tries to sell you silver as a treatment for molluscum contagiosum is just selling you a hype, and you will be wasting your money uselessly. You might as well just rub a silver spoon on your molluscum bumps because it has the same effect. It will do nothing to treat your molluscum. Save your money and avoid it.
There is no scientific (or non-scientific) evidence that colloidal silver can be used to treat molluscum. While it is legal to sell colloidal silver as a DIETARY SUPPLEMENT, in 1999 the FDA banned over-the-counter sales and banned labelling it as having any therapeutic benefits. Some Internet sites still market it as beneficial, usually under another name, or simply as "silver". Some even go as far as claiming it has benefits for flus, colds, cancer, diabetes and aids. This is illegal in the United States, and basically what they are trying to do it prey on people's desperation and steal their money. Many of those websites that sell colloidal silver products go around pretending to be users of the product and post made-up benefits on various health-related forums.
Avoid colloidal silver or any other silver-related products being marketed as beneficial for molluscum contagiosum. It is just a marketing hype with no documented benefit. Check with the FDA if you have any doubt.
My Rating for Colloidal Silver: 1/10
