Cowhage is used to expel the round worm, which it does by wounding it
with the fine prickles.
_Dose_ of the confection, for a child three or four years old, a
teaspoonful early, for three mornings, followed by a dose of castor
oil. (_See par_ 491.)
The mechanical anthelmintics are strictly confined to those agents
which kill the worm in the body by piercing its cuticle with the sharp
darts or spiculae of the cowhage hairs, or the fine metallic points of
powdered tin (_pulvis stanni_). When these drops are employed, they
should be given in honey or treacle for ten or fifteen days, and an
aperient powder every fourth morning, to expel the killed worms.
