Abstract

Abstract A silver-ionic water having the pH of not more than 5 or not less than 8 and silver ion concentration of 0.03 to 10 ppm. The silver-ionic water can be used as a bacteriostatic water, a growth promotive acidic water for plant cultivation, a growth promotive alkaline water for plant cultivation, a therapeutic water for pathogenobacterial skin diseases and external cavity mucosal diseases, a wound-curative water, a disinfectant water, or a therapeutic water for digestive organ mucosal diseases and keratoconjunctivitis.
