TEXEZUELAN MEDICINAL PLANTS. 279 
Jargest quantity of Cehadllla is sent to Hamburg and Philadelphia. 
The export, however, diminishes from year to year. The powder of 
the seeds, mixed with honey, is administered by practitioners against 
intestinal worms, beginning with two grains a day, and gradually in- 
creasing the doses to ten, 
Ceholla {Allium Cepa^ L.). Two or three drops of the juice are 
said to cure sinp;infi: in the ear. But some cotton with Oleum rutce 
must be put into the entrance of the ear, so after all the onion may 
not be the most efficacious part of the remedy, Tour or six spoonfuls 
of water, wherein an onion had been placed for twenty-four hours, 
are considered to have an anthelmintic effect. 
Cedro (Cedrela odorata, L.)- This lofty tree yields excellent timber, 
and is also medicinal. The powdered bark is used for bathing w^ounds 
and ulcers, and also acts as a mild emetic. The gummy substance which 
exudes from the stem, enters into the composition of a much used eye- 
water- The hard wood is of a bitter taste, and is not attacked by 
insects; but it is rather brittle. I have seen a perfectly sound board, 
nearly five feet long and one inch thick, resting with its ends on strong 
square beams, broken in an almost straight line, under the weight of a

Cereza (^MalpigJiia glahra, L., and other sp.). The astringent fruits 
are not only used by w^ay of dessert, but likewise in cases of dysentery, 
here called Pujo, very common, especially at the beginning of the rainy 
season, and sometimes exceedingly difficult to stop. The Cereza-stones, 
powdered, and taken in wine with some resin of the same tree, are 
good for pectoral complaints. 
Ceri^aja {BrachyrampJms intyhacens, De Cand,), The milky sap 
applied to sties, cures them speedily.

Challota or Chayota {Sechiun edule, Sw.). The vernacular name 
is of Aztec origin. The insipid fruit is used for poultices, and ap- 
plied to irritated parts of the skin. 
ChiqincJiique (Cassia hrflo7'a^ L.), Common near houses. The 
leaves, soaked in cold water, make a refreshing draught, principally 
taken in fevers caused by insolation, but also in intermittents. Of 
the leaves poultices for the insolated parts of the skin are made. 
Chirca^ Chilca. Plants from San Carlos (south of the lake of Valen- 
cia) sent under .this name, proved to be Jacquinia ai'millaris, L, In 
the neighbourhood of Caracas it is not met with, and another plant, a
