Ricinus communis has a strong vitality and adaptability. When I was young, in the village where my hometown was located, whenever there was a small piece of open space in front of and behind my house, I was planted with Ricinus communis, which really can be seen everywhere. Moreover, Ricinus communis has a strong adaptability, and it can grow vigorously with a similar piece of land. When I was young, I didn't know that castor beans were poisonous, and I often picked them and threw them on my friends, because the castor beans were wrapped with small thorns that could stick to clothes. I used to pick them for fun.

why did many people grow castor in rural areas before?

This is because castor is a treasure all over the body. For example, the stem bark of castor can be used to make hemp rope. In our hometown, even children knew how to make it, and the hemp rope made is very durable.

Ricinus communis is one of the top ten oil crops in the world. Energy plants? Castor bean is rich in oil components, even under the ordinary production process, the oil yield can reach about 45%. Castor oil is a kind of non-drying oil with light yellow viscosity and no volatility, which is very biodegradable. Because it comes from plants, it is very environmentally friendly. Castor oil prepared from castor oil has high burning point, low freezing point and high specific gravity, so it is often used as a natural lubricant in chemical industry, light industry, electromechanical and other fields. Moreover, especially the refined castor oil can also be applied to aerospace and military industry.

Ricinus communis leaves can be used to make environmentally-friendly insecticides and mosquitoes. This is because ricinine, ricin and other toxic substances are contained in Ricinus communis leaves. Ricinus communis leaves can be dried and ground into powder, and then enough water can be added to make natural insecticides and mosquitoes.

In addition, castor can also be used as medicine. From these aspects, it is not an exaggeration to say that castor is full of treasures.

Although the economic value of castor is very high, there are deadly toxins hidden in the castor plant, and the most toxic part is castor bean. As the seed of castor bean, it contains ricinine and ricin, among which ricin is the most toxic to human body and one of the strong natural toxins. Studies show that ricin is toxic to all mammals.

According to some data, even the raw castor seeds in the wild may lead to death if children eat 2-7 seeds by mistake, and death if adults eat 2 seeds by mistake, and poisoning is caused by eating castor beans by mistake. The incubation period after poisoning is also very long. Most of them begin to show symptoms 3-24 hours after eating castor seeds by mistake. The symptoms are: fever, vomiting, nausea, abdominal pain and diarrhea, throat irritation, and in severe cases, high fever and bloody stool.

Up to now, there is no specific detoxification drug, and only symptomatic treatment can be carried out according to the cause, so the cause should be determined as soon as possible before treatment, otherwise the best treatment opportunity will be delayed. After it is confirmed that it is ricin poisoning, gastric lavage and drainage should be carried out at the first time, and at the same time, fluid replacement and diuresis should be carried out, and the toxin in the body should be eliminated as much as possible by using hemoperfusion technology to achieve the purpose of treatment.

Because ricin is easy to be prepared, this strong natural toxin is easy to be used by terrorists for sabotage, and may also be made into extremely destructive toxin warfare weapons. At the end of 197s, a BBC reporter was assassinated. The weapon used by the murderer was a poison prepared from ricin. The murderer put the poison into a special umbrella. When he pretended to bend down to pick up the umbrella, he shot out a small cylinder the size of a needle. The small cylinder contained ricin, and released the toxin after entering the human body. According to the autopsy results, the BBC reporter died only because he was injected with about .45mg of ricin. It can be seen that
