250 SPECIFICS FOR THE ALIMENTARY TRACT 



colocynth, and is attended with much griping, pain and prostration. 

 In overdoses it is a violent poison. 



Therapeutics. Elaterin is not used to any extent in veterinary 

 medicine but would be indicated, if at all, in those cases where we 

 desire profuse, watery discharges, such as congestion of the brain, 

 ascites, uremia, poisoning, etc. It is contraindicated in inflamma- 

 tions of the digestive tract and pregnancy. 



CAMBOGIA 



Synonyms. Gamboge, Pipe Gamboge 

 This is a gum resin obtained from Oarcinia Hanhurii, a medium 

 sized laurel-like tree of Siam. It occurs as a yellow powder. 



Doses. Cattle. 3ij— §j ; 8.— 30; 



The action and uses of gambogia are similar to those of the 

 other hydrogogues, but it is not of much use. It is too irritant for 

 dogs and horses and practically never used alone, but usually asso- 

 ciated with other cathartics, as epsom salts. One ounce of gamboge, 

 with one-half pound each of epsom salts and common salt in one 

 quart of water make an efficient purgative for cattle.

 gTowa on the eastern slopes of the Mexican Andes. It contains two 

 glucosides, convolvulin and jalapin.

The action and uses of jalap are similar to the other hydrogogues, 

 so they will not be discussed again. It is but little used in veter- 

 inary medicine.
