 principle is an essential oil, which can be obtained by distillation. The 

 root has been employed in medicine since the time of Hippocrates. 

 By the moderns it is successfully used in the intermittent fevers, 

 even after bark has failed, and is certainly a very useful addition to 

 Cinchona. It is also a useful adjunct to bitter, and stomachic infusions.
