PoporHYLiin, Resin of.—Is prepared in the following 
manner :—Mandrake root is exhausted by percolation with 
rectified spirits. The spirit is then distilled off, and the 
remaining liquid slowly poured into three times its volume of 
water. The deposited resin is afterwards washed on a filter 
with distilled water and dried. The resin acts as a drastic 
purgative, not unlike jalap or scammony resins; it how- 
ever, differs from them in its power of causing an increased 
secretion or flow of bile. That it frequently causes an emptying 
ofthe gall bladder is certain, but its operation in increasing 
the secretion of bile is doubted by some, for if many 
evacuations, they say, are caused by its action, the latter ones 
are of a mucous character rather than bilious. It is much 
used for congestion of the liver. Dose: } to 1 grain. 
Dangerous. 9d. per drachm. |

power. It also checks the sweating of extreme debility. As 
an antiperiodic, quinine acts as a specific in ague, malarious 
remittents, miasmatic, neuralgia, hepatic and splenic engorge- 
ments. Quinine is able to cure or relieve certain forms of 
neuralgia, which are not due to malaria. As an antipyretic, 
doses of 5 to 15 grains have a marked effect in reducing 
temperature in pyrexia, to whatever cause it may be due. It 
has also been employed in the continued fevers. Dose: tonic, 
1 to 8 grains; antiperiodic, 5 to 15 grains. In divided doses, 
use it carefully, as serious consequences have accrued from 
large doses. 1s. per drachm.
