lO'i  MEDICINAL  ACONITIA  AND  ITS  SUBSTITUTES. 
aconitia  and  extractive  matter.  From  this  the  weaker  prepara- 
tions are  made  by  dilution,  and  the  stronger  by  evaporation, 
thus  : 
Tinctura  Aconiti  Radicis,    U.  S.  P. 
Take  of  Normal  solution  of  aconite,  three  fluid  ounces. 
Alcohol,  twelve  fluid  ounces. 
Mix  them. 
Fleming's  Tincture  of  Aconite  Root. 
Take  of  Normal  solution  of  aconite,  five  fluid  ounces. 
Alcohol,  ten  fluid  ounces. 
Mix  them. 
Aconite  Liniment. 
Take  of  Normal  solution  of  aconite,  half  a  pint. 
Glycerin,  a  fluid  ounce. 
Evaporate  the    solution  to  seven    fluid  ounces,  add  the 
glycerin,  and  mix  them. 
Aconite  Plaster. 
Take  of  Normal  solution  of  aconite  root,  half  a  pint. 
Adhesive  plaster,  a  sufficient  quantity. 
Evaporate  the  solution  of  aconite  until  it  assumes  the  consist- 
ance  of  thick  honey,  then,  having  weighed  it,  add  as  much  ad- 
hesive plaster,  previously  melted,  as  will  make  the  whole  weigh 
sixteen  ounces. 
Extractum  Aconiti  Radicis. 
Take  of  Normal  solution  of  aconite,  half  a  pint. 
Evaporate  it  carefully  on  a  water  bath  until  reduced  to  the 
proper  consistence  for  an  extract. 
In  regard  to  the  merit  of  this  mode  of  proceeding,  it  can  be 
said  that  it  assures  the  thorough  extraction  of  the  aconite,  and 
promotes  uniformity  in  the  strength  of  the  preparations,  and 
also  aff'ords  a  very  great  convenience  to  the  dispenser,  who  can, 
by  preparing  a  quantity  of  the  strong  solution,  quickly  produce 
the  other  preparations  at  will,  in  quantities  to  suit  his  require- 
ments.
