ANTISPASMODICS.

Antispasmodics are a class of remedies which relieve cramps,
convulsions, and spasms, and are closely allied to nervines. Indeed some
authors class them together. The following are a few of the most
important antispasmodics:

ASSAFETIDA (_Assafetida Ferula_). This is a powerful antispasmodic. It
is employed in hysteria, hypochondria, convulsions, and spasms, when
unaccompanied by inflammation. _Dose_--Of the gum or powder, from three
to ten grains, usually administered in the form of a pill; of the
tincture, from one-half to one teaspoonful.
