- Subject: Re: Poinsettias
-
- It's time to settle the poinsettia argument (yeah, right.) I went to
- the library and read several books on poisonous plants.
-
- >From "Plants poisonous to people in Florida and other warm areas", J. F.
- Morton, 1971:
- Poinsettia: Toxicity: "The sap is caustic like that of other members of the
- genus. [...] People who carry the trimmings to their trash piles in their
- bare arms sometimes acquire dermatitis similar to that from poison ivy.
- [In] March, 1955, the writer saw blisters on all fingers of a young woman who
- had merely transplanted a small poinsettia that had been given her in a pot
- at Christmast time.
-
- Internally, the sap is highly irritating and very toxic in quantity. Small
- children in Florida have complained of burning in the mouth and throat from
- sucking a stem, a leaf or flower-bud. They usually quickly desist because
- of the acrid and bitter taste. In Jan., 1965, a 2 1/2 year old child in
- Rochester, NY was exceedingly ill from eating a poinsettia leaf. Dr. H.L.
- Arnold related in _Poisonous Plants of Hawaii_ that a 2 year old child ate a
- poinsettia leaf, experienced vomiting, diarrhea, and delirium and died, in
- 1919. [...] Cattle are poisoned by grazing on the plant but a large bush
- was consumed by a goat in Costa Rica without apparent harm.
-
- >From "Poisonous plants of the Central United States", H.A. Stephens, 1980:
- Poinsettia: Only one human death has been reported from eating the leaves
- of the poinsettia.
-
- >From "A field guide to poisonous plants and mushrooms of North America",
- C.K. Levy, R.B. Primacle, 1984:
- Poinsettia (tissue irritant)
- As is the case with all Euphorbiaceae, its white milky sap is irritating,
- but the poinsettias, like many a handsome specimen, has a very bad
- reputation which may be undeserved. In 1919 there was a report of a child
- in Hawaii dying after eating poinsettia leaves, and in 1965 there was a
- two-and-a-half-year-old in Rochester, New York, who became ill after eating
- poinsettias. However, the leaves are bitter tasting, and most children will
- spit them out. They will irritate the mouth, the sap is a potent irritant
- of the eyes. Some laboratory studies with extracts of the plants failed to
- show any highly toxic substances, but any potent irritant will produce
- gastrointestinal symptoms if swallowed. Still, to be on the safe side, keep
- the plant out of the reach of small children.
-
- So, I suggest updating the FAQ as follows:
- F. The red leaves of Poinsettias (aka the Xmas Plant) are deadly poisonous.
- ["The Poinsettia Myth" in TMP]
- T. Poinsettia sap and leaves are highly irritating and can harm small children.
