As an expert in the field of colloidal silver, I can provide you with information regarding its concentration measurements. Colloidal silver is often measured in parts per million (ppm), which is a common unit for expressing the concentration of a substance in a given mixture.

The ppm for colloidal silver can vary widely depending on the intended use. For example, in some consumer products like health supplements, the concentration might be as low as a few ppm, while in industrial applications or for wound care, it might be much higher, ranging from 10 ppm to 100 ppm or more. It's important to note that the safety and efficacy of colloidal silver at different concentrations are subjects of ongoing debate and research, and the optimal concentration can depend on the specific application.

To ensure safety and effectiveness, it's crucial to follow guidelines provided by relevant health authorities or to consult with a healthcare professional when using colloidal silver products.

PPM of colloidal silver needs to be understood in its entirety. PPM means parts per million. By definition 1 PPM is 1 milligram of silver deposited in 1 liter of water (1,000 ml) (1,000,000 mg). If one were to ingest that 1 mg.read more >>
