Ancusa,  Anchusa  tinctoria,  Lin.;  the  root  is  used  for  coloring 
pomades. 
Angelica,  the  root  of  Angelica  Archangelica,  Lin.  Dose,  in  powder, 
5  to  10  gm. ;  the  infusion,  15  gni.  to  one  liter  of  water. 
Angostura  verdadera,  the  bark  of  Gal i pea  officinalis,  Hancock,  etc. 
Dose  of  powder,  2  to  4  gm.  ;  of  extract,  0*5  to  10  gm.;  little  em- 
ployed. 
Anis  comun  and  Anis  estrellado  are  Anise  and  Star-anise. 
Anisillo  cimarron,  Schkuhria  abrotanoides,  Roth,  a  Mexican  compo- 
site, is  anti-spasmodic. 
Anona  reticulata  and  A.  glabra,  Lin.,  Mexican  custard  apple.  The 
fruit  is  edible ;  the  decoction  of  the  bark,  leaves  and  green  fruit  is 
reputed  to  be  astringent  and  used  in  diarrhoeas ;  the  infusion  of  the 
leaves  is  anti-spasmodic;  Ihe  powder  of  the  seed  is  employed  as  an 
insecticide  and  is  dangerous. 
Anil,  Indigo,  is  little  used  medicinally. 
Apio,  Parsley,  is  aperitive  and  used  in  infusion  of  15  to  30  gm.  to 
the  liter. 
Arbol  de  la  cera,  Myrica  jalapensis,  Kunth,  nat.  ord.  Myricacea3,  is 
indigenous  to  the  sierra  of  Huauchinango.  The  wax  obtained  from 
the  fruit  by  boiling  with  water  is  green  or  yellow,  according  to  the 
method  of  extraction,  more  brittle  and  unctuous  than  bees'  wax,  has  a 
feeble  odor,  a  slightly  bitter  taste  and  a  density  nearly  equal  to  that  of 
water  and  melts  at  43°  ;  but  on  exposure  the  fusing  point  rises  to  47"5°. 
It  is  wholly  soluble  in  boiling  ether,  insoluble  in  water,  sparingly 
soluble  in  cold  alcohol  and  dissolves  in  20  parts  of  boiling  alcohol, 
depositing  the  greater  part  on  cooling ;  alkalies  saponify  it  readily. 
It  has  probably  the  same  composition  as  myrtle  wax  from  Myrica 
cerifera.  It  is  given  internally  in  powder  against  diarrhea  and  jaun- 
dice, and  is  used  for  making  candles,  for  adulterating  bees'  wax  and 
as  a  substitute  tor  the  latter  in  pharmaceutical  preparations.  The 
bark  of  the  root  is  acrid  and  astringent,  and  in  larger  doses  emetic.
