Antispasmodics are medicines which are intended to counteract 

 excessive muscular action, called sjja.s??i, or, in the limbs, cramp.

APERIENTS. 



(Physic Balls and Drenches.) 



Aperients, or purges, are those medicines which quicken or 

 increase the evacuations from the bowels, varying, however, a good 

 deal in their mode of operation. Some act merely by exciting the 

 muscular coat of the bowels to contract ; others cause an immense 

 watery discharge, which, as it were, washes out the bowels; whilst 

 a third set combine the action of the two. The various purges 

 also act upon different parts of the canal, some stimulating the
