This salt is introduced into the Phar, U. S. because much | 
_ used by American practitioners. The late Dr. Samuel 
Powell Griffitts used it extensively as a febrifuge tonic. Dr. 
Zollikoffer, of Baltimore, commends it in intermittents.—= 
May be given during the paroxysms—in the apyrexia, indis- 
_ criminately. Dr. Worthington, of Washington, has used it 
in uterine hemorrhage, which it checks, while it assuages _ 
the priate on: uipice it may depend. His dose is 3j. As 
a febrifuge tonic, the dose is, grs. v to x, twice a day. B 
the recommendati wiow of the late Dr. Grilith, Lused it re- 
peatedly in the fever of 1823 and 1824, ing in this 
city and neigh d, and can attest to the efficacy of 
its tonic powers. I cured many cases by a mer- 
curial purge, this salt, and centaury drink freely. I gave 
the prussiate in 10 grain doses three times a day, and 
often every two hours. It is an American practice, desery-_ 
ing of further trials, and would be a good subject fora 
practical inaugural dissertation, by which, if judiciously _

Native of the south of Persia, growing on the : 
mountains, in 
the provinces of Chorasaan and Laar, where it is named 
kingisch. Kempfer has described it in the Ameenitates exo- 
tice, 535, with a figure 536. Stem nine feet high. Seeds 
have a porraceous odour, and ‘a sharp bitter taste. The | 
drug’ is obtained from the roots when 4 years old, by twist. 
ing the stems off at the corona, when the plant has be 
to decay, removing the earth from the upper portion of the 
root, and cutting it transversely. After 48 hours, the juice, 
which has flowed spontaneously in the sun, is scraped off, 
and another transverse incision made, This is repeated 3 
successive times, when the root is allowed to remain una 
touched for 8 or 10 days, at which time another excision 
is made. After this, the root perishes. The juice, collected 
from a number of roots, is put together, and dried in the 
sun; it is then the drug of commerce. is
