494  Comparison  of  Galenical  Preparations.  {^^"(£"^1883*^*^' 
Rub  the  extract  with  the  water  until  uniformly  soft,  then  gradually 
add  the  petrolatum  and  mix  thoroughly.  Very  much  preferable  to 
the  officinal,  in  the  treatment  of  hemorrhoids. 
Ungue^itum  Sulphuris. — Sulphur  Ointment. — Sublimed  sulphur, 
thirty  parts;  petrolatum,  seventy  parts.  Rub  the  sulphur  with  the 
petrolatum,  gradually  added  until  they  are  thoroughly  mixed.  Prob- 
ably no  better  than  the  officinal. 
Unguentum  Sulphuris  Alkalinum. — Alkaline  Sulphur  Omt- 
ment. — Washed  sulphur,  twenty  parts ;  carbonate  of  potassium,  ten 
parts ;  water,  five  parts ;  petrolatum,  sixty-five  parts.  Rub  the  sul- 
phur with  the  carbonate  of  potassium  and  the  water,  gradually  add  the 
petrolatum,  and  mix  thoroughly.  Preferable  on  therapeutic  grounds, 
to  the  officinal. 
Unguextum  YERATRiNiE. —  Veratrine  Ointment. — Veratrine,  four 
parts;  alcohol,  six  parts ;  petrolatum,  ninety-six  parts.  Rub  the  vera- 
trine with  the  alcohol  in  a  warm  mortar  until  dissolved,  then  gradu- 
ally add  the  petrolatum  and  mix  thoroughly.  This  ointment  is  much 
darker  in  color  than  the  ointment  formerly  officinal,  due  to  the  com- 
plete solution  of  the  veratrine.  When  made  from  petrolatum  it  is 
probably  more  efficient  than  when  made  from  lard,  because  of  its  more 
rapid  absorption. 
Unguentum  Zinci  Oxidi. —  Ointment  of  Oxide  of  Zinc. — Oxide 
of  Zinc,  twenty  parts  ;  petrolatum,  eighty  parts.  Rub  the  oxide  of  zinc 
with  twenty  parts  of  petrolatum  previously  melted,  until  the  mixture 
is  perfectly  smooth  then  add  the  remainder  of  the  petrolatum  and  mix 
thoroughly.  This  ointment  does  not  equal  the  officinal  in  appearance ; 
it  is  not  white  nor  does  it  have  the  pleasant  balsamic  odor  due  to  the 
benzoin,  but  when  used  to  allay  irritation,  as  in  acute  eczema,  the  oint- 
ment made  from  petrolatum  will  frequently  be  preferred.
