DRUGS AND THEIR USES 3 



Camphor. — In combination with other agents it is applied as a 

 stimulant to sprained tendons, ligaments, and joints. Internally it is used 

 to arrest catarrh and cough, to check diarrhoea, and to relieve gaseous 

 distension of the abdomen. 



Cantharides. — As a counter-irritant and vesicant it is applied to the 

 skin over the region of joints, tendons, and ligaments to remove chronic 

 enlargements, and to the throat, sides of the chest, and other parts in acute 

 disease of internal organs. 



Carbolic Acid. — Destroys low organisms; antiseptic, disinfectant, 

 and deodorizer. Used in the treatment of wounds and the disinfection 

 of stables, stable utensils, surgical appliances, &c. Inhaled from a nose-bag, 

 it proves serviceable in nasal catarrh, strangles, and influenza. 



Carbonate Of Ammonia. — As a stimulant, combined with vegetable 

 tonics, it is useful in influenza, strangles, and other specific fevers. As an 

 expectorant it is given in bronchitis and broncho-pneumonia. It is also 

 serviceable in indigestion, flatulence, and colic. 



Carron Oil. — This is a mixture of lime-water and olive or linseed oil. 

 It is used as an application to burns or scalds. 



Catechu. — A powerful astringent. Very efficacious in diarrhoea when 

 combined with chalk, opium, and aromatics. 



Chalk (Precipitated). — Useful as an antacid in indigestion, and as 

 an astringent in diarrhoea. Usually combined with opium and aromatics. 



Chloral Hydrate. — As an antiseptic it destroys low organisms and 

 prevents decomposition, but its chief action internally is exercised on the 

 brain and spinal cord, by which it produces sleep and arrests convulsions. 

 It is given in tetanus, chorea, spasmodic asthma, and colic. 



Chlorate Of Potassium. — Used mostly as a gargle or wash in 

 aphtha and superficial ulceration of the mouth, and as an electuary 

 in catarrhal sore-throat. It is sometimes given in strangles, purpura 

 hemorrhagica, and other specific fevers, under the idea that it destroys 

 the poison in the blood by giving up its oxygen. 



Chloric Ether. — Stimulant; antispasmodic and anodyne, useful in 

 chills, colic, asthma, shock, &c. 



Chloride Of Ammonium. — Administered internally in bronchial 

 catarrh, congestion of the liver, and in rheumatism. Dissolved in water 

 with saltpetre and alcohol it forms a cooling application to the legs of 

 horses. 



Chloride Of Mercury (Calomel). — Calomel is used as a cathartic in 

 combination with aloes. It should, however, be given with care, lest super- 

 purgation be induced. It is also given in small repeated doses as an 

 alterative in chronic skin diseases, and in long-standing enlargement of
