Antispasmodics are useful in allaying cramp or spasm, but, as in the case of Alteratives, we do not know how they act. The chief ones are opium, ether, spirits of turpentine, and camphor, prescribed according to the following formulas:

9. - Laudanum.

Sulphuric ether, of each 1/2 to 1 drachm. Camphor mixture, 1 ounce.

Mix, and give in any ordinary spasm, as colic, etc.

An antispasmodic injection:

10. - Laudanum,

Sulphuric ether,

Spirits of turpentine, of each 1 to 2 drachma*

Gruel, 3 to 8 ounces.

Mix, and inject with a common clyster syringe.
