Internal. — The therapeutic value of tartar emetic is limited mainly 

 to canine practice. Antimony is still prescribed largely by the Germans 

 as a general and circulatory depressant and expectorant for horses. Gen- 

 eral depressant treatment has gone out of vogue and is not usually indi- 

 cated in inflammatory affections, and even if it were, antimony does not 

 exert such an action in any considerable degree upon horses or ruminants. 

 Aconite is a much more valuable and efficient circulatory depressant 

 than antimony for the horse. There are three indications for antimony 

 in canine practice: 1st, as an emetic; 2nd, as a general depressant in 

 inflammatory diseases and in strong patients; 3rd, as an expectorant in 

 acute bronchitis. The first indication is generally attained more promptly 

 and safely by zinc sulphate. The second and third indications may be 

 combined by prescribing antimony in the first, or dry stage of acute 

 bronchitis in dogs, in the form of hive syrup. For example: 



Syr. SciUae Co. 



Sp't's. Mther. Nitrosi aa 5ss. 



M. Llq. Ammon. Acetatis ad giv. 



S. Teaspoonful every 2 hours. 



Antimony may be employed as an emetic in bronchitis to clear the 

 stomach and upper part of the respiratory tract of secretions. Ipecac is, 

 however, a better and safer agent in dogs for this purpose, and antimony 

 is generally counter-indicated in the second, or exudative stage of bron- 

 chitis.

Ammonii chloridi aa Sss.

S. One powder on the feed t. i. d. 



Tartar emetic is useful in cattle to overcome paresis and impaction 

 of the rumen. 



The Germans prescribe tartar emetic very commonly to horses as a 

 parasiticide against round worms and tape worms. Four or five drams 

 are given in a pail of water to the fasting animal, and followed by the 

 administration of a dose of oil. Tartar emetic has recently been given 

 intravenously in trypanosomiasis, its action resembling arsenic prepara- 

 tions.
