Properties: 



Mustard is used for the irritating oil developed in the presence of moisture. It 

 is a powerful, though not rapid, rubefacient and counterirritant, becoming a painful 

 vesicant if applied too long a time. Usually an application for 20 minutes secures 

 ample rubefaction. Mustard was formerly much used for emetic purposes, but is bet- 

 ter supplanted by something less irritating to the gastric mucosa. 



SULPHUR. 



Sulphur is official in three forms: Sulphur Lotum, or Washed Sulphur; Sulphur 

 Praecipitatum, or Milk of Sulphur; and Sulphur Sublimatum, or Flowers of Sulphur. 

 The Washed Sulphur is best for internal use, the precipitated form for ointments, and 

 the sublimed form for disinfection.
