Gels containing the medicinal ingredients of licorice were formed by dissolving herbal medicinal plants into a biocompatible zwitterionic cellulose solvent and successive precipitation. The licorice gels gradually released glycyrrhizic acid, the main medicinal ingredient in licorice, within 3 h. Although the licorice gels were mechanically weak, the gel strength was improved just by the addition of cellulose during the preparation of the gels.
