124      Materia  Medica  of  the  Mexican  Pharmacopoeia.  { *mM_l™h,  Searm' 
Violeta  espanola  (sweet  violet  petals),  are  mentioned  as  medicinal 
articles. 
Tanibata,  Ipomoea  stans,  De  Cand. ;  Convolvulaceae ;  in  the  moun- 
tains of  Guadalupe.    The  root  is  purgative. 
Taray  de  Mexico,  Varennea  polystachya,  De  Cand.;  Leguminosae; 
in  the  ravines  of  Mochitiltic,  near  Puebla,  &c.  The  wood  is  seen  in 
commerce  in  pieces  of  various  dimensions;  bark  fissured,  reddish 
brown;  wood  yellowish  with  a  brownish  tint,  some  layers  reddish, 
compact;  taste  sweetish  and  astringent  when  fresh,  and  after  drying 
slightly  astringent.  The  infusion  is  used  in  diseases  (epizootias)  of 
chickens,  and  the  decoction  in  inflammations  of  the  kidneys  and  of 
the  bladder.  For  this  wood  that  of  "  palo  dulce,"  Eysenhartia  amor- 
phoides,  of  the  same  natural  order  is  frequently  substituted;  it  is 
readily  distinguished  by  its  white  color.  The  taray  of  Europe,  Tama- 
rix  gallica  is  not  used  in  Mexico. 
The  gum,  which  exudes  spontaneously,  is  in  small  agglutinated 
fragments,  superficially  opaque,  the  fractures  glossy  and  vitreous,  red- 
dish brown,  resembling  kino;  odor  faint;  taste  very  astringent  and 
free  from  bitterness.  According  to  Oliva  it  consists  of  tannin  with  a 
small  quantity  of  coloring  matter  and  impurities.  It  has  the  same 
medicinal  properties  as  tannin  and  may  advantageously  be  substi- 
tuted for  kino. 
Te  limon,  a  cultivated  grass,  probably  Andropogon  citratus,  Be 
Cand.  The  infusion  of  the  leaves,  1:250,  is  used  as  a  digestive  stimu- 
lant and  antispasmodic. 
Te*  de  Milpa,  Bidens  tetragona,  De  Cand.;  Compositae;  in  the 
Mexican  valley,  &c.  The  leaves  after  having  been  transiently  sub- 
jected to  the  action  of  boiling  water,  then  dried  and  rolled  like  Chinese 
tea,  are  used  like  the  latter.  Mendoza  found  them  to  contain  tannin, 
fat,  concrete  volatile  oil,  protein  compound  and  coloring  matters. 
Bidens  leucantha,  De  Cand.,  is  known  by  the  same  name  and  the 
leaves  are  used  in  a  similar  manner. 
Tecomate,  Crescentia  Cujete,  Lin.;  Bignoniaceae ;  in  hot  districts. 
The  pulp  of  the  fruit  is  used  in  various  affections  of  the  liver  and  for 
its  pectoral  properties. 
Tejocote,  Crataegus  mexicana,  Mocmo  et  Sesse;  Rosaceae;  indige- 
nous and  cultivated.  The  decoction  of  the  root  has  antidysenteric  and 
diuretic  properties,  and  that  of  the  fruit  is  pectoral ;  the  latter  yields 
an  abundance  of  jelly  and  is  much  used  as  an  aliment.
