PART USED AND PREPARATION.—The fresh plant, gathered when the | 
flowering season is about half completed and the fruits rapidly forming, is chopped 
and pounded to a pulp and weighed. Then two-thirds by weight of alcohol is 
taken, the pulp thoroughly mixed with the spirit and the whole pressed out ina 
piece of new linen, The tincture thus prepared has, after filtration, an orange- 
brown color by transmitted light, a peculiar odor, resembling decayed vegetation, 
a pungent taste, too like its odor, and an acid reaction. 
CHEMICAL CONSTITUENTS.—Several partial analyses have been made of 
this plant, but none have resulted in the separation and determination of a pecu- 
liar principle. The general constituents of plants, and a volatile oil said to be 
identical with oil of mustard, as well as a fixed oil, have been determined. 3 
Clinical Uses.—In the absence of provings of this drug, it has been found 
curative in various uterine hemorrhages, especially those with which uterine cramp 
and colic are associated ; also in various passive hemorrhages from mucous sur- 
faces.* A thorough proving is greatly to be desired.
