Are Poinsettia Plants Poisonous? Fact or Fiction?

Myths and rumors about the toxicity of the
poinsettia plant are common late in the year, when the popular red-leaved plants
take center stage in holiday
decorations. While the genus (Euphorbia) to which the poinsettia plant belongs
does contain some highly toxic plants, the popular poinsettia itself is not
toxic. Some sources attribute the rumor about the dangers of poinsettia leaves
to a case of poisoning in 1919 that led to the death of a two year-old child. At
the time, the cause of the poisoning was incorrectly determined to be a
poinsettia leaf.
According to the POISINDEX information source - the
primary resource used by the majority of poison control centers nationwide - a
child who weighed 50 lbs. would have to eat over 500 poinsettia leaves to reach
an even potentially toxic dose of compounds in the poinsettia plant. Doctors at
the Children's Hospital of Pittsburgh and the Pittsburg Poison Center conducted
a review of 22,793 reported cases of poinsettia exposures, the majority (93%) of
which occurred in children, and found that 92% of those exposed did not develop
any symptoms at all. Ninety-six per cent of those exposed were not even treated
in a health care
facility. Furthermore, no deaths resulting from poinsettia ingestion have ever
been documented.
Even though accidental ingestion of poinsettia leaves
will not damage your body or kill you, it may lead to nausea and vomiting in
some cases. Since the taste of poinsettia leaves is reportedly very unpleasant, it is unlikely that a
child or animal who attempts to eat or chew the leaves will continue to do so
after the first taste. While ingestion of house plants is never a good idea
(some popular plants can be extremely dangerous when eaten) parents of young
children can be assured that the poinsettia plant is not a dangerous risk in the
home.
