In Europe _euphorbia lathyris_ has been found to produce in animals,
colic, constipation, tympany, followed by bloody diarrhœa, stupor and
hæmaturia. In America the euphorbia corollata (large flowering spurge)
and euphorbia ipecacuanhæ (ipecacuanha spurge) though less potent have a
similar action. _Treatment_ consists in favoring elimination by emesis,
and abundant mucilaginous and demulcent agents.
