ECZEMA. 391 



In cases of extensive redness of the skin we must apply com- 

 presses of lead-water or thymol (1 per cent.), creolin (1 to 2 per 

 cent.), carbolic-acid water, thiol water (20 per cent, thiol, liquid, 

 50 per cent, glycerin, and 50 per cent, water); but powdering is 

 preferable, as every skin is not benefited by liquid applications. 

 As soon as the marked symptoms of the disease have decreased 

 we may replace the use of powder by ointments of zinc or lead, 

 white precipitate ointment, or by mild ichthyol soaps. 



(6) In very moist eczema with a prolonged course the use of 

 powder is not always successful. In those cases we must apply 

 drying fluids, such as corrosive sublimate solution (1 to 1000), 

 nitrate of silver solution (2 per cent.), twice daily by means of a 

 brush or a cotton tampon. Sublimate ointments (1 per cent.) or 

 subiodide of mercury (2 per cent.) are beneficial, but strong solu- 

 tions of blue-stone or crude sulphate of iron and tormentilla root 

 are not to be recommended.

(c) In cases of pustula we may use the same treatment as is 

 indicated in b, after having pressed out and emptied the pustules. 

 The author has also obtained good results with ichthyol liniment 

 and salicylic ointment (see Acne). 



(d) In eczema when it has reached the scaly stage we must first 

 clean the skin thoroughly with some mild, non-irritating soap, but 

 not carbolic or tar soap. The best kind to use is Castile, ivory, 

 or a pure potash soap of the Pharmacopoeia. The author has had 

 good results from "Hebra's" alcoholic potash soap :

Hebra's soap is poured or rubbed upon the surface which is
