To provide an ionized salt-added parenteral solution which enables the direct supply of a minus ion into a human body to improve the flow of humor and the like and activate the cells of the body, by adding an ionized salt, and to provide a method for producing the same.

This ionized salt-added parenteral solution is obtained by charging sodium chloride into a minus-ionized quartz crucible for a prescribed time, calcining the charged sodium chloride in the crucible at a place for a prescribed time to produce an ionized salt, and then preparing a saturated salt solution from the obtained ionized salt. At the place, a negative charge-imparting means made by sealing minus-ionized granular or powdery Si or SiOx [0<(x)≤2] in a glass tube is buried in the ground. When the prepared saturated salt solution is injected into the proper site of a human body, the minus ion is efficiently supplied to the human body to improve the flow of the humor and the like and further activate the cells of the body.
