This plant is originally from America,but is naturalized in Europe. [Fig. FloreMedic. IV. 232.)
The herb and seeds are employed.
The herb (Herta Datttrœ seu Stramoniiseu Solani maniaci) is composed of a thick,
fistulous, very ramified stem, with slightlycompressed branches, somewhat grooved,furnished with large, petiolated, alternate,glabrous, ovo-angular leaves, sinuated onthe borders, the angles unequal and veryacute. It has a virous and repulsive smell,and a bitter and nauseous taste.
The seeds are reniform, slightly com-pressed, and rugose ; they are blackishwithout, and white within, inodorous, andof a nauseous taste.
Thisplant contains, according to Brandes,a peculiar alcaloid, Daturinum, Datu-rina, Daturia, which is the source of itsactivity.
The Datura fastuosa, Linn., is, accord-ing to Ainslie, employed in the EastIndies ; it exhibits the same properties.
It is excitant, and is reputed anti-spas-modic and narcotic. It is extolled in con-vulsive affections, neuralgia, and rheu-matism.
Dose, from one to twenty grains, pro-gressively increased, of the powder.
