Camphor is of benefit in exhausting acute diseases (influenza, pneu- 

 monia and canine distemper), for the same reason, and because it pos- 

 sesses diaphoretic and antipyretic properties. It may be combined with 

 alcohol, spirit of nitrous ether, and ammonia compounds, in these affec- 

 tions. 



Respiratory disorders are improved by camphor, since it is an expec- 

 torant, diaphoretic, stimulant and antiseptic. It is prescribed in spas- 

 modic cough, bronchitis and pharyngitis. For the latter, in electuary 

 with belladonna. 



Camphor is a valuable drug in diarrhea, particularly in the serous 

 variety, and in that form following exposure to cold. It is not useful in 

 inflammatory conditions, but checks secretion and pain. Camphor is pre- 

 scribed alone in diarrhea, or with brandy and laudanum.

 of the genito-urinary tract. Camphor has proved of service in purpura 

 hemorrhagica of horses given thrice daily in pills (gr. 75).
