510 Classified List of Drugs, 



PURGATIVES OR CATHARTICS. 



Th-ese are designed to bring about evacuation of the bowels. They 

 are an exceedingly valuable class of remedies. The principal ones are — 



Aloes, 



Salts (Epsom, Glauber and common salt), 



Oils (linseed, castor, Croton). 



Aloes are especially useful in horses ; the salts and the oils, in cattle 

 and sheep. The rules for their administration and formulas for their 

 proper combination will be found in the alphabetical list. 



STIMULANTS. 



These are intended to give prompt assistance in an exhausted condi- 

 tion. The strength they confer is not lasting, therefore too much re- 

 liance should not be placed upon them. But in many emergencies they 

 are invaluable, and save life when nothing else will. The main ones 

 are — 



Alcohol. ("WTiisky, brandy, gin, wine, ale, etc.) 



Ether. 



Carbonate of ammonia. 



Turpentine. 



Ginger. 



Where there is active inflammation or high fever, stimulants should 

 be withheld ; but in wearing chronic disease and in crises of profound 

 nervous exhaustion, they can be administered with advantage. 



TONICS. 



These are intended to sharpen the appetite, and increase the nervous 

 vigor, and thus impro^ve the health generally. They should not be given 

 to already healthy animals, as they are not beneficial ; nor should they 

 be continued for too long a period, as they lose their effect. Small doses 

 should be given at regular intervals, for one or two weeks, and then 

 should be suspended for a few days, or another tonic substituted. They 

 are either of animal, vegetable or mineral origin, as 



Sulphate of iron. (Copperas.) 



Sulphate of copper. (Blue vitriol.) 



Arsenic. 



Vegetable bitters. (Peruvian bark, gentian, quassia, etc.) 



Alcohol. 



Cod-liver oil. 



As the mineral tonics are generally nxore active than those from the 

 vegetable conditions, they are generally prescribed for horses and 

 cattle ; or the two forms are combined.
