Datura is poisonous. Why are there many ethnic groups in front of and behind rural houses?
Datura Datura, also known as Solanum lyratum Thunb, Datura flower and Solanum lyratum Thunb, is widely distributed in China and distributed in almost every province and city.
Datura stramonium is toxic to the whole plant, among which fruit is the most toxic, young leaves are the second, and hay is the least toxic. Symptoms usually appear after eating for about half an hour. If the dose is small, the symptoms will disappear on their own. If the dose is large, it may lead to drowsiness, spasm and even death.
Datura stramonium once participated in a poisoning incident in history as a poison. 1908, some Vietnamese wanted to poison the maharaja of Hanoi, France, so they arranged for the chef to add Datura flower to the dinner of the French garrison. However, a chef went to church and told the French priest. Despite this, nearly 200 French people were poisoned. In history, this event was called:? River city poisoning incident? .
The toxic components of Datura stramonium are mainly scopolamine, atropine and scopolamine, among which atropine can stimulate or inhibit the central nervous system, while scopolamine has a sedative effect on the brain.
The toxic effects of these alkaloids on people are mainly to excite the central nervous system first and then inhibit it. Therefore, after poisoning, the sympathetic nerve of human body will be highly excited, which will stimulate brain cells to produce strong turmoil, stimulate the reflex system of essence and gas, and cause convulsions and spasms.
Datura stramonium poisoning is life-threatening, but it can be treated as long as the treatment time is timely, and the treatment success rate is high. This poisonous creature can be seen everywhere in rural areas of China because Datura stramonium has strong adaptability to the environment and low requirements for the environment, so it can often be seen in rural fields.
Why is Datura toxic? Datura stramonium is toxic because toxicity can be used for self-protection. We know that animals can move, and when they are in danger, they can run to protect themselves from harm. But plants can't. Plants can't escape when they are hurt. Different plants have evolved different coping mechanisms in order to protect themselves and avoid being eaten part of themselves.
Some plants have evolved bitter taste, which makes animals feel bad after eating, thus avoiding being eaten. Some plants have evolved thorns, which hurt each other through sharp parts and make them give up eating themselves. Other plants have evolved toxicity, and Datura is such a creature. This is because the digestive system of mammals will destroy the seed activity of Datura stramonium and make its offspring have low survival rate. In this environment, they have evolved corresponding toxicity.
The pharmacological action of Datura stramonium is toxic, but in Chinese medicine, Datura stramonium is actually a blind medicinal material, which can relieve asthma and can be used as anesthesia during surgery. Often mentioned in martial arts novels? Sweat medicine? It is said that the raw material is Datura stramonium.
Scopolamine is the main component of Datura stramonium, which can inhibit sweat gland secretion and relax muscles. According to Compendium of Materia Medica, Datura stramonium was picked in August, dried in the shade with hemp seed, and then served to San Qian with hot wine. He will fall asleep after a while, and it won't hurt to have an operation at this time.
Although Datura stramonium has pharmacological effects, it can only be used at moderate doses. Once the dose is exceeded, the drug will become poison. With the progress of science, we have been able to extract the effective components of plant pharmacology and purify the pharmacological components of Datura stramonium for treatment. However, some pharmacological components have toxic effects themselves, so they can also be produced while treating diseases? Side effects? However, considering that the medical effects and side effects of the drug obviously outweigh the disadvantages, the ingredient will still be used for medical treatment, but there will be a guiding dose and it is not allowed to be taken in excess.
To sum up, Datura stramonium is very common, because it is not particularly toxic and almost no one will eat it. And its adaptability is very strong, as long as people don't deliberately destroy it, it can take root and sprout in the field and survive.
