Experts explain:
1, why is oleander so poisonous?
Answer: Its toxic ingredients are similar to those of cardiotonic
"The toxicity of oleander mainly comes from the digoxigenin component contained in it, which is mainly in the leaves, stems and roots. Both fresh leaves and dry leaves are toxic." Huang Peipei, chief physician of the emergency department of Jiangsu Provincial People's Hospital (The First Affiliated Hospital of Nanjing Medical University), told reporters that the ingredients of digitalis are actually very similar to those of clinically used cardiotonic drugs. The main hazards are Cause malignant arrhythmia , leading to sudden death. Toxic ingredients can also irritate the gastrointestinal tract, so patients may experience nausea and vomiting. In some movies and TV dramas, miscarriage caused by the use of oleander is also possible. The main reason is that digoxin induces contraction of uterine smooth muscle.
"Poisoning is related to dose and effect, and toxicity cannot be discussed without dose. If the dose of poisoning is large, treatment will be very difficult." Chief Physician Huang Peipei said that oleander causes poisoning, and there is no direct detoxification method in China. The "antidote" for patients is to first use measures to induce vomiting and gastric lavage to prevent further absorption of toxins; in more serious cases, where malignant arrhythmia occurs, there are now many rescue methods, such as Hemodialysis is used to remove toxins from the body, ECMO (extracorporeal membrane oxygenation technology) is used to support patients' cardiopulmonary function, etc., and comprehensive life support methods are used to help patients overcome difficulties.
2, the whole plant is poisonous, why is it widely cultivated?
Answer: Easy to feed or "environmental protection guardian"
Some citizens are curious, since the whole oleander plant is poisonous, why do many cities like to plant it?
Li Mei, a flower doctor at Zhongshan Botanical Garden, said that in addition to its beautiful tree shape and gorgeous flowers, oleander also has the effects of resisting smoke, dust, poisons and purifying the air.

In addition, oleander has tenacious vitality, a long flowering period, and a fast growth rate, taking shape in two or three years. Oleander is often used as a roadside tree.

Digging herbs and wild vegetables can lead to poisoning after taking them. "For example, Datura , some people believe that plants in the Datura family can cure rheumatism and pain, so they go to the mountains to dig them up and make medicinal wine. The emergency department of Jiangsu Provincial People's Hospital treats several cases of poisoning every year. ."
