spirit that of the aromatic. It imparts its virtues to water in dis- 
tillation along with a small quantity of essential oil, amounting 
only to two ounces from fifty pounds of the root, according to 
Hoffman; but Neuman and Cartheuser obtained the oil in a much 
larger proportion. ; 
The root of Calamus, though not heating like the spices, mani- 
fests to the taste considerable pungency, and a moderate share of 
bitterness, and has therefore been deemed useful as a warm 
stomachic, and was ae much used here in combination with 
the more ition, were rendered 
more - grateful and catminntve: It has been reco ded in 
vertigo, proceeding from a vitiated stomach,* and in intermittent 
fevers, which we are told were cured by this root, after the bark 
had failed. We are also informed of its efficacy in scorbutic and 
hemorrhagic complaints ;* but to this, little credit will be given, 
and much less to the supposed elexipharmic power of Calamus, 
though it is an ingredient in the theriaca and mithridate of 
dignified memory, and still is much used in eastern countries 
as’ a preservative against contagion.
