PaRTs USED In Mepicinz, anp Mopr or PREPARATION.— 
The root must be taken before the plant flowers, therefore 
before the month of June, and the juice is to be expressed 
from it, and prepared according to the mode previously men- 
tioned of preparing the recent plant. The root has a very 
nauseating, biting taste and disagreeable smell. It grows some-

different to that of the Bryonia dioica, being more branched 
and more covered with tubercles.
