Cyanogen oxide is toxic enough to make people smell discolored, colorless and odorless, but only one drop can kill people, so it is listed as a prohibited product. And ricin is thousands of times that of oxide cyanogen, there is relevant news that 10 grains of castor is enough to kill, but it has been planted on a large scale in China, what the hell is going on.
I believe that many people have heard the name "potassium cyanide", which is more powerful than the deadly "Crane Top Red" in the film and television, not only through oral poisoning, the gas it plays is also enough to be deadly.
The harm of ricin to humans is even thousands of times more powerful than potassium cyanide, and its toxin is extracted from castor beans, which only takes about 0.2 mg to take the life of an adult, which can be called a fierce role in poison. Relevant data show that even if the castor beans have not been extracted at high concentrations, if they accidentally eat about 10 or so, they can cause children to die of poisoning.
Seeing this, I believe many people will think of China's nursery rhyme "I grow castor for the motherland", more than ten years ago, many rural areas in Our country have castor figures, at the beginning it was because castor can be sold for money and was planted in large quantities. Because castor beans can be pressed into high-grade industrial oil, they can also be made into aviation lubricants, paints and coatings and other chemicals, especially as lubricating oil, which can significantly improve the service life of the machine. It can be seen that castor oil has a major role in industrial development, so it was for this reason that large-scale cultivation was once planted in rural areas of China at that time, which can improve the economic benefits of the planting land.
Although castor seed was later poisonous and was not allowed to be replanted, its seeds were already scattered throughout the country due to previous large-scale cultivation. And because castor is not only resistant to high temperatures and barrenness, so there are many rural places have this phenomenon, although castor is no longer cultivated, but in the field or on the side of the road, you can always find wild castor. For children, they do not know that the fruit with petals is castor, and they do not know that castor is toxic, so children are easy to eat when they play, so every year there are always children who go to the hospital for gastric lavage because of the accidental consumption of castor beans.
Accidentally eating castor beans can also save lives through gastric lavage, which is a blessing in misfortune, mainly because children eat them by mistake, most of them are swallowed directly, and the ricin released without biting is relatively limited.
Unlike the poison that kills instantly, ricin is not that it will not be poisoned immediately in a short period of time, but inhibits the synthesis of human protein through ricin protein to achieve the process of apoptosis of human cells, which is also known as "the most perfect assassination weapon".
The most successful use of ricin in history is the bizarre death of the writer George Markov, if he was not a well-known current political critic at the time, or he did not take the experience of the day as a joke before the poisoning, then it is estimated that the cause of death of this writer would have sunk to the bottom of the sea. According to the relevant description, George Markov went to work as usual on the morning of the murder, but when he passed by someone on the road, he suddenly felt a tingling sensation in his legs, turned his head to see a passerby holding an umbrella, and frequently apologized to himself, when George Markov thought that the pain caused by the accidental scraping of the umbrella of a passerby, and the passerby also apologized.
But no one expected that this brief passing was the key moment when George Markov was killed and poisoned. Although he did not die of poison during the day, he began to have a high fever that night, and even if he was sent to the hospital in time, he was not treated. After George Markov's death, it was found that he had a hollow steel ball of only 1.7 mm in size on one of his legs, and that an ampere toxin emanated from it poisoned George Markov to death. Many people began to suspect that George Markov was assassinated, and this speculation was publicly admitted by the former Head of Bulgarian Intelligence after the incident, indicating that Markov was indeed assassinated, and that it was the Bulgarian government that issued the assassination order, and that the assassination was carried out by the Soviet KGB and the Bulgarian intelligence service at that time, using a "poison gas umbrella gun".
The reason why George Markov was assassinated was because he had publicly attacked the Bulgarian government, and because of its great influence in the local area, it triggered a "common hatred" among many people. Unexpectedly, even though Markov had left Bulgaria to live in Britain, he was still on the assassination list. After Markov's successful assassination, ricin became famous. Since then, ricin has become a common tactic in the assassination community. Moreover, the use of ricin in assassinations is not only in the past, but also in recent years, such as the previous two U.S. presidents.
According to relevant news reports, a person who sent a letter to then-US President Barack Obama was sentenced to 25 years in prison for releasing ricin, but such a heavy sentence was repeated during the Trump era, and the letter sent to then-President Trump contained ricin and was intercepted by the Pentagon.
Ricin only requires a small amount to cause death, and colorless and odorless is more conducive to murder and causes international fear. I believe that many people will be curious, since ricin is a poison, then is there also an antidote, is it possible to save ricin?
In fact, ricin does not have an antidote, although many species in nature may have symbiotic plants that can detoxify the toxin, but ricin is artificially extracted in castor beans, and no antidote has been found. After being infected with ricin, even though medical technology is very developed today, it is impossible to untie ricin and save lives.
Because ricin plays a fatal role in ricin is the castor protein, which can inhibit the synthesis of human protein cells, and finally lead to apoptosis, in this process, poisoned people are often high fever, and accompanied by severe pain, breathing becomes more and more difficult, and even at the time of death, you can clearly feel the pain of the body but can not breathe on your own, and finally die in extreme pain.
In fact, it is not difficult to infer that it is precisely because there is no antidote to ricin and it is difficult to use existing medical technology to rescue the poisoned person that it will be used as a "weapon" in the assassination operation. After all, everyone knows that the people who can be added to the assassination list are "big people", and the assassination operation must be put to death once it starts, so the lethality of ricin is self-evident.
