History 
The oleoresin of ginger was prepared in 1834 by Beral, a 
Frenchman, but was apparently first brought to the notice of 
American pharmacists by Proctor in 1849. It was intro¬ 
duced into the United States Pharmacopoeia in 1860 and is still 
official at the present time. While the oleoresin has never 
been officially recognized abroad, a similar preparation is said 
to be used extensively in England under the name of gingerin. 1

For this drug, the present pharmaeopceial definition is as 
follows: “The dried rhizomes of Zingiber officinale Roscoe 
(Fam. Zingiberaceae,) the outer cortical layers of which are 
often either partially or completely removed. Preserve it in 
tightly-closed containers, adding a few drops of chloroform or 
carbon tetrachloride, from time to time, to prevent attacks by 
insects.” The official drug has also been described in the 
literature under the following botanical synonyms: Amomum 
Zingiber Linne, and Zingiber Zingiber (Linne) Rusby.
