FORMULA  FOR  THE  FLUID  EXTRACTS. 
EXTRACTUM  ZINGIBERIS  FLUIDUM. 
From  Jamaica  Ginger,  in  powder.    No.  60. 
Remarks.— This  is  a  new  class  of  Fluid  Extracts  embracing 
the  more  important  aromatics,  and  stimulants  owing  their  virtues 
to  oleoresins.  By  the  employment  of  Atwood's  deodorized  alcohol 
of  95  per  cent.,  the  menstruum  does  not  depreciate  the  odors,  and 
when  the  concentrated  portion  is  added,  but  little  if  any  pre- 
cipitation occurs.  Several  of  the  extracts  are  more  appropriate 
for  dental  purposes  than  medicine,  instance  the  Pellatory,  Ele- 
campane, Xanthoxylum,  Orris,  and  Myrrh,  although  most  of 
them  may  be  used  in  medicine.  The  Fluid  Extract  of  Cubebs 
as  thus  made  has  some  advantages  over  the  oleoresin  in  mix- 
tures that  are  not  emulsive.  The  preparations  of  cloves,  carda- 
mom and  ginger  are  admirable  carminatives  for  pills  or  mixtures, 
and  the  capsicum  affords  a  stimulant  for  external  application 
well  fitted  as  an  addition  to  liniments,  where  a  decided  impression 
is  needed. 
By  combining  the  fluid  extracts  of  ginger,  cloves  and  cin- 
namon in  the  proportion  of  a  fluid  cunce  of  the  former,  to  half 
a  fluid  ounce  each  of  the  two  latter,  a  liquid  is  obtained,  which, 
when  applied  by  means  of  two  or  three  layers  of  lint  or  Canton 
flannel,  saturated,  affords  an  excellent  extemporaneous  spice 
plaster.  Or  a  compound  fluid  extract  may  be  made  by  the  fol- 
lowing formula. 
EXTRACTUM  AROMATICJE  FLUIDUM. 
Take  of  Ginger  in  powder,  eight  ounces. 
Cloves  "  four  ounces. 
Cinnamon      "  four  ounces. 
Alcohol,  a  sufficient  quantity. 
Mix  the  powders,  moisten  them  with  four  fluid  ounces  of  alco- 
hol, pack  them  in  a  percolator,  cover  the  surface  with  a  disc  of 
cloth,  and  pour  on  alcohol  until  two  pints  have  slowly  passed. 
Reserve  the  first  twelve  fluid  ounces,  evaporate  the  remainder 
to  four  fluid  ounces,  and  mix  it  with  the  reserved  tincture  and 
filter. 
When  it  is  desirable  to  increase  the  stimulation  of  this  appli- 
cation, add  a  small  quantity  of  capsicum. 
In  the  preparation  of  these  fluid  extracts,  the  powders  should 
be  as  fine  as  possible,  provided  the  substances  are  not  injured
