CROTON OIL — RED IODIDE OF MERCURY 



Croton oil and red iodide of mercury serve also as irritants. 

 The former is generally too irritant for use upon any animal except 

 cattle, the latter is very useful as a deep acting vesicant in diseases of 

 the bones and tendons. 



Chloroform, camphor, and aconite are employed as rubifacients, 

 practically always in the form of a liniment.
