Preparation.—"Take of pareira root, in No. 40 powder 1 pound (av.), boiling distilled water, a sufficiency. Digest the pareira root with a pint of the water for 24 hours, then pack in a percolator, and, adding more of the water, allow the liquor slowly to pass until about a gallon has been collected, or the pareira is exhausted. Evaporate the liquor by a water-bath until the extract has acquired a suitable consistence for pills"—(Br. Ph.).

Medical Uses and Dosage.—(See Pareira). A diluted alcoholic menstruum will, in our opinion, make a better preparation, and one freer from inert matter. Dose, 10 to 30 grains.
