This process is essentially that of the National Formulary (1st ed.), which comments as follows: "The essential oils used in this preparation, particularly those of orange and lemon, must be as fresh as possible, and absolutely free from any terebinthinate odor or taste. They should be diluted as soon as received, with a definite quantity of deodorized alcohol, which will retard deterioration. They should not be kept in stock, undiluted, for any length of time, or should at least be kept in bottles completely filled, and in a dark place. The alcoholic solution should be kept in the same manner. If oil of Curaçao orange of good quality can be obtained, it is advisable to use this, in place of ordinary oil of orange, as it imparts to the spirit a finer flavor"—(Nat. Form.).
