PREPARATIONS OF VALERIAN. 
nected with the production of this new camphor, but as yet 
experiments are wanting. Mr. Schliesser prefers to get 
more complete determinations, before he gives the results 
of the ultimate analysis he has made. 
"The oil as obtained, contains all the medicinal constitu- 
ents of the root, and in practice has been found t to be identi- 
cal with some fine samples of French manufacture. Indeed, 
the use of the natural fresh root for its production, insures 
a very perfect product, while the process is the result of the 
labors of all the eminent chemists who have studied the 
products of valerian to the present time," 
Prof. Phelps, of Dartmouth College, speaking very highly 
of its efficacy, says : — " In your method of preparation/the 
active principle is detached from the nauseating constitu- 
ents of the root, and obtained in solution. We may look 
upon the Fluid Extract, as a solution of valerianic acid." 
Prof. Cleaveland, of Brunswick College, says : — tC It con- 
tains the active, medicinal principle of valerian in a purer, 
more simple and concentrated statet han any other prepara- 
tion of the root with which I am acquainted. Dr. Stedman, 
of the City Institution, Boston, says: — " In many cases 
where opium is inadmissible as a narcotic, anodyne, or 
antispasmodic, this Extract of Valerian seems to answer the 
indication quite perfectly." Professors Mottand Parker, of 
this city, have also expressed their good opinion of this 
preparation. It is confessedly a simple extract, made by 
boiling the fresh root in pure water, with the addition of a 
little alcohol as a preservant. From the trial which I have 
given it, I am convinced that it will be found to supersede 
the use of assafcetida, musk, camphor, castor, &c, in a 
great degree. In a majority of cases I have found that 
from twenty drops to a teaspoonful, is an ordinary dose, 
repeated as often as every half hour, if necessary. In de- 
lirium tremens much more can be advantageously adminis- 
tered. — Boston Med. and Sw*g. Journ., fromNew York
