the skin. The animal should be controlled by tying up the head, or 

 using a cradle, or side-bar attached to the halter and surcingle, to pre- 

 vent horses from biting the blistered area. The tail should be tied up 

 if the blister is applied within its reach. Dogs should be muzzled, but 

 are apt to rub the sore spot. The serum discharged from the blister 

 must be continually sponged off with soap suds and water, to prevent 

 excoriation of the subadjacent skin, or the latter may be covered with 

 rosin cerate, or, better, a solution of rosin in alcohol, by means of a 

 brush. 



The blister is washed off in 36 or 48 hours after its application, and 

 vaseline should thereafter be kept on the part. The use of cantharidal 

 blisters is contraindicated in weak or young animals, usually in dogs ; on 

 the flexures of joints; or delicate skin on the inner aspect of the upper 

 part of the limbs ; on acutely inflamed areas ; and in renal disease. 



Uses Internal. — Cantharides is rarely administered internally. It 

 is sometimes successful in stopping incontinence of urine, when due to 

 relaxation of the neck of the bladder, and it may be used as a stimulant 

 in chronic cystitis and pyelitis. Cantharides is recommended to increase 

 sexual desire in cows and mares, but it has usually to be given in toxic 

 doses to produce an aphrodisiac action. The tincture should be employed 

 when the drug is exhibited internally.
