Anti-tumor aqueous solution, anti-cancer agent, and methods for producing said aqueous solution and said anti-cancer agent

A method for producing an antitumor aqueous solution for killing cancer cells, comprising:

• an aqueous solution preparation step of preparing an aqueous solution through addition, to water, of a solute containing at least one of disodium hydrogen phosphate (Na2HPO4), sodium hydrogen carbonate (NaHCO3), L-glutamine, L-histidine, and L-tyrosine disodium dihydrate (L-tyrosine.2Na.2H2O);
• and
• a plasma irradiation step of irradiating the aqueous solution with atmospheric pressure plasma generated in a plasma generation region by means of a plasma generator.

An antitumor aqueous solution for killing cancer cells, produced by dissolving, in water, a solute containing at least one of disodium hydrogen phosphate (Na2HPO4), sodium hydrogen carbonate (NaHCO3), L-glutamine, L-histidine, and L-tyrosine disodium dihydrate (L-tyrosine.2Na.2H2O), to thereby prepare an aqueous solution, and irradiating the aqueous solution with atmospheric pressure plasma.
