LIST OF MEDICINES. 457 



Castor is stimulant and antispasmodic (reducing pain). It 

 is used in lock-jaw and hysteria. The dose is from one to 

 two drams of the substance itself — from four to six drams of 

 the tincture. 



Castor-oil. — This article is only spoken of for the purpose of 

 warning those who may be tem2:)ted to rely on it as a physic 

 for the horse, of its utter uncertainty and frequent danger. It 

 would have to be given in a pound or pound and a half dose, 

 and even then it would be uncertain. 



Catechu. — This is one of the best astringents used. It may 

 be used in the form of powder, or the tincture may be given. 

 The dose is fi'om one to two drams of the powdered drug; 

 of the tincture, one to two ounces. It is useful in violent 

 purging, or scours. But it is best to give medicine to correct 

 the condition of the bowels, or give it in combination with such. 



Caustic ])otash is one of the most active caustics. It is found 

 in round sticks in the stores. It dissolves or .eats the flesh 

 away where it is applied very fast. It produces pain like a 

 coal of fire or hot iron. The stick may be used to open deep 

 ulcers or abscesses. 



Common potash. — The common potash is used as a cure for 

 fistula and poll-evil. The pipe, or sinus, is stuffed full of the 

 potash. A most powerful inflammation is excited, and large 

 quantities of matter are thrown out. The inflammation and 

 swelling commence to go down in a few days, leaving a whitish 

 pipe sticking up, which readily comes out. All that is then 

 necessary to effect the cure is rest, and, in some cases, simple 

 dressings, as wet cloths, or some mild salve. 



Cayenne Pejijyer. — This article is generally found as a red 

 powder, and known by the name of caimcum. It is stimulant, 

 carminative, (removing wind), and antispasmodic (relieving 

 pain). It may be used wherever a quick and powerful stimu- 

 lant is necessary. The dose is from ten to twenty grains. It 

 is often used in combination with other remedies. It is some- 

 times used in the form of tincture, which see.
