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.

Yellow Jessamine.]

YELLOW JESSAMINE (_Gelseminum Sempervirens_). The root is the part used.
This is a valuable remedy in various

diseases when associated with restlessness and a determination of the
blood to the brain; also in the neuralgia. _Dose_--Of the fluid extract,
three to eight drops; of the concentrated principle, Gelsemin,
one-fourth to one grain. The use of this drug by non-professional
persons should be attended with great caution.

VALERIAN (_Valeriana Officinalis_). The root is the part used. Valerian
is an effective remedy in cases of nervousness and restlessness.
_Dose_--Of the infusion, (one-half ounce to a pint of water) one-half
ounce; of the tincture, one-half to two tablespoonfuls; of the
ammoniated tincture of valerian, from one-half to two teaspoonfuls in
sweetened water or milk; of the valerianate of ammonia, one-half to
three grains.
