178 a. OLEUM CAMPHORS. OIL OF CAMPHOR. Obtained in the sublimation 

 of camphor from the wood. It is a reddish liquid with a slight yellowish 

 tint, and is probably a mixture of a hydrocarbon and camphor. It resembles 

 the latter in medical properties, but is more of a stimulant, and is especially 

 applicable to those cases of bowel complaint or spasmodic cholera in which 

 an anodyne and stimulant effect is wanted. This volatile oil must not be 

 confounded with Linimentum Camphorae, the common name for which, with 

 many, is oil of camphor. Dose: 2 or 3 njj (0.13 to 0.2 mil).
