lODOFORMUM. I J 3 



ACTION AND USES. 



The action of creaaote is, practically speaking, the same 

 as that of carbolic acid, to which the student is referred. 

 Before the latter came into general use, creasote was not 

 unfrequently employed for the same purposes internally to 

 which carbolic acid is now put; hut the uncertainty of its 

 composition and strength, as a complex product, renders it 

 inferior to phenol in this respect. 



The Unguentum is employed in dry skin diseases. The 

 Vapor is disinfectant and deodorant in phthisis, chronic bron- 

 chitis, gangrene, and other diseases of the lungs attended by 

 foul discharges. A combination of creasote, iodine, and various 

 volatile substances such as ether, chloroform, and spirit, has 

 lately become popular as a constant inhalation in phthisis. The 

 Mistura Creasoti is intended chiefly as a remedy in vomiting, 

 especially when this is due to pyloric obstruction, dilatation of 

 the stomach, and the development of fermentation ; but it has 

 also been recommended in the vomiting of pregnancy, hysteria, 

 and sea-sickness. 



A specific and remote local effect has lately been claimed 

 for creasote, when given by the stomach, namely, as a dis- 

 infectant and deodorant in phthisis with antipyretic and healing 

 properties.

 1. IMMEDIATE LOCAL ACTIOX AND USES. 



Iodofonn is an antiseptic and disinfectant, but destroys 

 organisms less readily than carbolic acid. It is a very powerful
