Zusammenfassung:PROBLEM TO BE SOLVED: To provide a glycyrrhizinic acid or its salt without precipitating or gelling for a long period and physicochemically stable in pH 5.5-8.5 range and approximately 1 osmotic pressure range by using a non-toxic additive for a living body. SOLUTION: This aqueous solution of e.g. a high concentration aqueous solution of ≥50 mg/mL glycyrrhizinic acid or its salt comprises 0.1-5.0 w/v% arginine or histidine. COPYRIGHT: (C)2007,JPO&INPIT
