 Sig. External use. 



Zinc ointment is used externally in the form of a dust- 

 ing powder, ointment or paste. In eczema, erythema and 

 scratches, the zinc oxide ointment is valuable and can be 

 combined with carbolic acid (gr.x. to § i.) or creolin (5 per 

 cent.) to great advantage, when itching is a prominent symp- 

 tom. Still better than zinc ointment is a paste containing 

 zinc oxide, 2 parts ; starch and vaseline, each 3 parts. Zinc 

 acetate can be used in all cases as a substitute for zinc 

 sulphate.
