Is poinsettia poisonous

There are two theories about whether poinsettia is toxic or not. Some people think that the whole plant of poinsettia is toxic, the milk of stems and leaves is easy to irritate human skin, and it may be poisoned to death when eating stems and leaves by mistake. Another theory is that poinsettia is not toxic, and there are experiments that have proved that the experimental mice did not show signs of death or poisoning. Poinsettia, also known as ivory red, old Laijiao, Christmas flowers, Christmas red, poinsettia, is a kind of discolored foliage plant native to Central Africa. For the two theories of poinsettia toxicity, the analysis is as follows:

Some people think that poinsettia is toxic, mainly considering that poinsettia belongs to Euphorbiaceae, and most Euphorbiaceae plants are toxic. These people think that the whole plant of poinsettia is poisonous, and the white milk in its stem contains a variety of toxic alkaloids, which will irritate the skin. If the skin comes into contact, it can easily lead to allergic symptoms such as redness and swelling, fever, strange itching and local papules, such as accidental ingestion of stems and leaves. Mild cases lead to gastrointestinal reactions and nervous disorders, severe cases are extremely easy to die of poisoning.

Another theory is that poinsettia is non-toxic. In 1971, Ohio State University in the United States conducted a special study on the toxicity of poinsettia. But poinsettia has been proved to be non-toxic and no part of poinsettia poses a danger to humans or animals. Only a small number of experimental mice showed red skin, runny nose and so on.

Can poinsettia be put in the bedroom

Flower friends are not advised to put a poinsettia in the bedroom. Because:

1. Poinsettia is a short-day plant, but it likes light, while the light in the bedroom is generally weak, so it is suitable to put some shade-tolerant plants, such as asparagus, copper grass, tortoise back bamboo and so on.

2. Poinsettia is colorful and easy to attract children and pets at home. Children and pets will have allergic symptoms after eating by mistake, so the children's room must not be placed.

3. Bedroom plants require simplicity and convenient management. Poinsettia is not easy in management. It takes time to water, fertilize, control temperature and humidity, and so on. The most suitable plant for bedroom display is succulent plant, which is small and does not take up space. It is also very hardy and easy to manage.
