The benefits of silver have been appreciated for many centuries and it has been long prized for its protective qualities. The use of silver as an anti-microbial agent actually began many years before the English nobility insisted on silver cutlery. Herodotus, the “Father of History”, accounts that no Persian king, including Cirrus, would drink water that was not transported in silver containers. During the early pioneer days in North America it was common practice to drop silver coins into the transport vessel to preserve water. Higher Nature Colloidal Silver contains particle sizes in the region of 0.6 - 5 nanometres. These small particles are in the nano-range and are naturally occurring. The small size of the silver particles is important because smaller particles provide a greater surface area per volume which in turn allows the silver to exert a greater effect. Made up of 17-21% particulate (colloidal)and 79-83% ionic. The only ingredients in this product are purified water and medical grade silver. Ideal for use at home, when out and about, or on your travels.
