ELATERINUM — ELATERIN 249 



powerful irritant when applied to the skin, exciting inflammation, 

 vesication and even pustulation. 



Internally. Croton oil contains some free crotonoleic acid, 

 which is irritant to the body tissues. It is decomposed in the small 

 intestines to Croton oleates which are much more actively irritating 

 than the ricinoleates. It is therefore a drastic purgative, producing 

 copious amounts of feces. Its action is attended with a great deal of 

 griping and oftentimes nausea. Large or excessive doses cause 

 gastroenteritis, accompanied by prostration and collapse. 



Therapeutics. Its internal use is almost entirely confined to 

 cattle practice, where it is used as a strong purgative. It is not 

 usually employed except as an extreme measure. 



Externally as a strong counterirritant, for blister, etc. It is often 

 used upon cattle but rarely on horses, as its action is very severe. 



Administration. It should be given by the mouth, mixed with 

 some bland oil or as an emulsion.
