Soak the gelatin in one and a-half times its weight of distilled water until quite soft, add the glycerin, heat gently on a water-bath until the gelatin is dissolved and the mass weighs 73.44 (11 3/4 ounces), add the sugar and citric acid, previously dissolved in the orange-flower water; then add the oil of lemon and solution of carmine, mix thoroughly, strain through muslin, and allow to solidify.
Glycogelatin is used as a basis for throat pastilles, the medicament being dissolved or suspended in the melted glyco-gelatin, the mixture poured into trays to solidify, and cut up into the required number of pastilles; or the melted mass may be poured into suitable pastille moulds. A firmer preparation, for stock pastilles, can be obtained by using 16 of gelatin, but it should be noted that the glycogelatin becomes firmer on keeping, owing to loss of water by evaporation.
