Largely employed as a domestic remedy, and known 

 in some parts of the country as THOROUGHWOKT. 

 Its activity depends upon a bitter extractive and 

 it, like the bitter aromatics generally, is much en- 

 hanced in action by the hot water in which its 

 infusion is made.

Euphorbia resinifera has a resinous juice, and it 

 is used as a rubefacient and vesicant; it is too irritant 

 for internal administration.
