[8 ozs. av., 142 grs.]; washed sulphur, eighty grammes (80 Gm.) [2 ozs. av., 360 grs.]; oil of fennel, four grammes (4 Gm.) [62 grs.]; sugar, in fine powder, five hundred grammes (500 Gm.) [1 lb. av., 1 oz., 279 grs.]; to make one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]. Mix the oil of fennel thoroughly with about one-half of the sugar, then add the remainder of the sugar and the other ingredients, and mix thoroughly. Finally pass the powder through a No. 60 sieve, and keep it in well-closed vessels"—(U. S. P.).
Formerly powdered fennel was employed in the preparation of this powder. It has now been replaced with oil of fennel, which renders the powder less liable to take on an unpleasant odor. Moreover, the proportion of liquorice is increased over that of the U. S. P. (1880) formula, giving a pleasanter and more easily prepared preparation.
Action, Medical Uses, and Dosage.—A very efficient laxative, operating kindly in doses of 30 to 60 grains, administered in plenty of cold water.
