from its toxic action. Unless the doses are excessive or frequently<br />

given, or given with oil, as castor oil, such accidents are less likely to<br />

occur. The treatment consists in stimulation by ammonia and purging<br />

by Epsom salt.<br />

Therapy.—A most certain taenicide, effectually removing tapeworm,<br />

especially the Bothriocephalus latus and the Taenia solium, and said to<br />

be less effective upon the Taenia medio-canellata. Prepare the patient in<br />

the usual manner over night for the administration <strong>of</strong> taenicides by<br />

purging and fasting. In the morning administer 30 grains <strong>of</strong> the<br />

oleoresin in capsules or flavored emulsion, follow at midday with a full<br />

meal without fats, and in the evening give a brisk saline cathartic.<br />

Under no circumstances must oils, especially castor oil, be given with<br />

it during the treatment. They favor absorption <strong>of</strong> the filicic acid,<br />

thought to be the toxic principle. Aspidium is seldom used; the<br />

oleoresin being preferred. The latter is also effectual against the hookworm<br />

( Uncinaria americana).<br />

ASPIDOSPERMA.<br />

The dried bark <strong>of</strong> Aspidosperma Quebracho-blanco, Schlechtendal (Nat. Ord.<br />
