With respect to the collection (harvesting) of the foregoing 
and their preparation for use, there is little of a general nature 
to be said as the plants from which these drugs are obtained 
differ so widely in their habits. This subject will, therefore, 
not be given consideration here, but will be discussed in Part II 
under the treatment of the individual preparations. 
Solvents Used. 
At the present time, ether is the solvent directed to be em¬ 
ployed in the preparation of the official oleoresins with the ex¬ 
ception of the oleoresin of cubeb which is prepared with alcohol. 
It will be recalled that the first of this class of preparations to 
make its appearance, namely, the Huile de Fougere of Peschier, 
was also prepared with ether. In fact, ether appears to have 
been the only solvent 2 ) given consideration in this connection 
by the early European investigators. 
1 One animal drug, cantharides, has been utilized for the preparation of 
an ethereal extract. This preparation, which was official in the Belgian 
Pharmacopoeia of 1854, cannot propterly be classed with the oleoresins since 
it contained no resin—the animal organism being free from constituents of 
this nature. 
a Buchner in 1826 experimented with alcohol in preparing the Extractum 
Filicis resinosum, while Brandes, in 1827, made use of a menstrum con¬ 
taining both alcohol and ether, namely the Liquor anodynus, for the same 
purpose. Later, 1828, Dublanc and Oberdoerffer employed alcohol in the 
preparation of the oleoresinous extract of cubeb.
