Active Silver contains Silver in a colloidal form which is known to have natural antiseptic & antimicrobial properties. Made using electro-controlled technology & very pure water from a 9-stage water purification process to achieve a very small particle size (0.0006 to 0.005 microns). This small particle size is important because it provides a much greater surface area for contact with bacteria & it is this which gives colloidal silver its disinfectant & antiseptic properties. Tasteless & safe even on small children. The 15ml refillable size with handy funnel is ideal for carrying in a bag or pocket. Use the 200ml non-spray-nozzle size to refill the 15ml & 100ml spray-nozzle sizes. Suggested intake & usage External Spray as needed into the back of the throat onto the skin & surfaces or use dropper to apply to ears or nostrils. Contents Purified water & 99.999% pure Silver at a concentration of 10ppm (parts per million). Suitable for use by vegetarians & vegans.
