Silver has been used for more than 2,400 years to help safeguard human health. It is a natural element that can be found in whole grains, edible and medicinal mushrooms, mammalian milk, spring water, sea water and tap water. - From the time of Hippocrates, silver's health protective properties have been well-known and vastly researched. Silver was used to help protect the purity and safety of drinking water throughout ancient civilizations.Confused? 10, 50, 250 or 500 PPM? - Some colloidal silver products of higher concentration (ppm) claim that one teaspoon equals multiple teaspoons of our 10 ppm product. On the contrary, scientific peer-reviewed literature has shown that silver is only useful when it is positively charged (bio-active). Bio-Active Silver Hydrosol, with greater than 98% bio-activity, is 8x more potent than a 250 ppm colloidal silver. Higher ppm also = risk of toxicity. There is simply no reason to use a higher ppm product.
