Disclosed is a method for dissolving hyaluronic acid and/or a salt thereof, in which a stirring tank provided with a stirring blade selected from a turbine-type serrated blade, a dispersion-type serrated blade, a dispersion-turbine-type serrated blade, an anchor-type serrated blade and a paddle-blade equipped serrated blade is used when dissolving hyaluronic acid and/or a salt thereof in an injectable solution selected from injection grade water, physiological saline, and phosphate buffered saline. The method for dissolving hyaluronic acid and/or a salt thereof enables large-scale production of injectable solutions of hyaluronic acid with a molecular weight of 1,500,000 to 4,000,000. |
