Prepared sagapenum (sagapenum præparatum—Ph. L.) is ordered to be prepared in the same manner as ‘prepared ammoniacum.’

Obs. Sagapenum is the feeblest of all the fetid gum resins.—Dose, 5 to 15 gr., made into pills; as an antispasmodic and emmenagogue.

SA′GO. Syn. Sago (Ph. L., E., & D.), L. “The fæcula (starch) from the stem of Sagus lœvis, S. Rumphii, and, perhaps, of other species of palms.” (Ph. L.) It forms the principal portion of the pith of the Sago palms, the Gommuti palm, the Talipot palm, and other allied trees. Its properties and uses, for the most part, resemble those of arrow-root. It is used for making puddings, jellies, &c.

Under the microscope the starch-grains of sago present an elongated form, rounded at the larger ends, and compressed at the smaller. They differ altogether in appearance from potato starch.

The pilum of the sago starch-grains is a point, or, more frequently, a crop, slit, or star, and is seated at the smaller end, whilst in the marsanta arrow-root the pilum is situated at the larger end. Rings are more or less clearly seen.

Sa′go, To Prepare. Wash an ounce of pearl sago in cold water; then boil it very gently in a pint of fresh water, stirring it frequently till dissolved. It may be flavoured with wine, spices, and sugar. For children, and for consumptive and debilitated persons, it will be found advantageous to substitute milk for water. The common sago being in larger grains, more time is required to dissolve it, and it is usually steeped for some hours before boiling it.

Sa′go Milk. (See above.)
