EXTRACTUM RHAMNI PURSHIANJE. 
Extract of Cascara Sagrada. 
Also official in British Pharmacopoeia. This solid extract and the 
Aromatic Fluidextract of Cascara Sagrada are two new preparations 
of the bark introduced into the Pharmacopoeia. Formerly, only the 
fluid extract was official. One part of the solid extract represents 
the activity of four parts b} T weight of the bark. 
Dose. — “Average dose: 0.250 Gm. = 250 milligrammes (4 grains).'’ 
(U. S. P.) This represents 1 Gm. (15 grains) of the bark and is equal 
to the Pharmacopoeial dose of the fluidextract, namely, 1 Cc. (15 
minims).

Proc. Arner. Pharm. Assoc., 1901, p. 288. 
EXTRACTUM SC0P0L.E. 
Extract of Scopola. 
This is prepared by evaporating, to a pilular consistence, the Fluid-

Pharmacopoeia.

FLUIDEXTRACTA. 
Fluidextracts.
