is it toxic?
Although they are popularly said to be toxic, but that is incorrect. However, it may cause nausea, diarrhoea, or vomiting if swallowed.
Poinsettia
Poinsettias are popularly, though incorrectly, said to be toxic to humans and other animals. This misconception was spread by a 1919 urban legend of a two-year-old child dying after consuming a poinsettia leaf. In 1944, the plant was included in H. R. Arnold's book "Poisonous Plants of Hawaii" on this premise. Though Arnold later admitted that the story was hearsay and that poinsettias were not proven to be poisonous, the plant was thus thought deadly. In 1970 the US Food and Drug Administration published a newsletter stating erroneously that "one poinsettia leaf can kill a child", and in 1980 they were prohibited from nursing homes in a county in North Carolina due to this supposed toxicity.

An attempt to determine a poisonous dose of poinsettia to rats failed, even after reaching experimental doses equivalent to consuming 500 leaves, or nearly of sap. Contact with any part of the plant by children or pets often has no effect, though it may cause nausea, diarrhea, or vomiting if swal
who introduced the poinsettia to the united states Joel Roberts Poinsett what is this introduced species? It is a commercially important plant species of the diverse spurge family (Euphorbiaceae).
