hemorrhagic, abortivant and vulnerary. Later it has been recommended as a 
substitute for ergot, as an excellent drug to control pulmonary hemorrhage, gene- 
rally as a diuretic, pectoral, diaphoretic, tonic, and a substance to be thought of in 
various forms of uterine trouble. 
The plant has no place in the U.S. Ph. The officinal preparations in the 
Eclectic Materia Medica are: Decoctum Senectt, Extractum Senecti Fluidum, and 
Senecit Oleo-resine. 
PART USED AND PREPARATION.—The entire, fresh, flowering plant, is 
chopped and pounded to a pulp and weighed. Then two parts by weight of 
alcohol are taken, the pulp mixed thoroughly with one-sixth part of it, and the rest 
of the alcohol added. After having stirred the whole, pour it into a well-stoppered 
bottle, and let it stand eight days in a dark, cool place. 
The tincture, separated from this mass by filtration, has a brownish-orange 
color by transmitted light, the peculiar odor of the bruised herb, a sweetish then 
slightly bitter taste, and a strong acid reaction. 
CHEMICAL CONSTITUENTS.—Senecin, an arbitrary oleo-resin, of unknown 
constitution. No analysis of the plant has been made, as far as I can determine. 
Upon adding the tincture to water a decided deposit of resin takes place, and 
tincture of iron shows the presence of tannin, even in a mixture of four drops of 
the drug-tincture in a drachm of alcohol. 
PHYSIOLOGICAL ACTION.—We have several provings of this drug, but its 
action is not determinable from them. |
