350 MEDICINAL TREATMENT IN GENERAL. 



Medicinal Hgctits. 



Are substances liquid, solid or gaseous, which are adminis- 

 tered with a view to their exerting some particular effect on the 

 animal economy by which changes incidental to a perversion of 

 normal conditions arising from any cause whatsoever may be 

 overcome and the subject restored to health. 



By the therapeutic action of a medicine, we mean 

 the result obtained on the system from the amount of a certain 

 drug necessary to alleviate or cure disease. By the physiological 

 action of a drug, we mean that action obtained on the system by 

 a drug which is the same both in health and disease. 



The following columns describing the therapeutics of the 

 common drugs used, doses and also a certain number of prescrip- 

 tions, are not written so much for the use of the veterinarian, 

 who by his education is specially fitted to know what agents are 

 indicatec} and how to combine them to meet certain conditions, 

 but for the sheep-owner, who can refer to them for guidance, the 

 matter being written in plain language without Latin terms, or 

 abbreviations, so that it can readily be understood, a slight 

 definition of certain terms describing the medicinal actions of the 

 drugs being all that will be necessary. 



Hstringcnts. 



Agents which cause a contraction of the tissues- 

 Hltcratiws. 



Drugs which by their modification of the nutrition over- 

 corne certain pathological conditions, permitting the parts to re- 

 turn to a healthy condition. 



Hntt-Spasmodics. 



Are feeble cerebral stiraulants, which by their action on the 

 nerve-centers increase their tone, thus overcoming minor spasms 

 and nervous conditions.
