"Senna, sixty grammes [or 2 ounces av., 51 grains]; Manna, one hundred and twenty grammes [or 4 ounces av., 102 grains]; Magnesium Sulphate, one hundred and twenty grammes [or 4 ounces av., 102 grains]; Fennel, bruised, twenty grammes [or 309 grains]; Water, a sufficient quantity, to make one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]. Pour eight hundred mils [or 27 fluid-ounces, 24 minims] of boiling water upon the senna, manna, and fennel contained in a suitable vessel, and allow the mixture to macerate for half an hour. Then strain, express and dissolve the magnesium sulphate in the infusion, and again strain. Lastly, add enough water through the strainer to make the Infusion measure one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]. This preparation must not be dispensed unless it has been recently prepared." U. S. (See Mistura Sennae Composita, Br.)
This preparation is used in Europe and to some extent in this country. The synonym, "Black Draught" has been deleted from the U. S. P. IX because of the similarity in name to "Black Drop" (Acetum Opii), death having resulted through the confusion in names. The taste is bitter and nauseous and the infusion is now rarely employed.
Dose, four fluidounces (120 mils).
