This plant, which is common in the countryside, castor beans, contains highly toxic seeds that can easily kill an adult with only 0.2 mg of toxin.
Based on this, ricin is often used as an assassination.
However, what is even more unexpected is that although castor beans are highly toxic, countries around the world still rush to it, and the United States regards it as a strategic material, and China's annual demand has reached 400,000 tons.
What do you want it to do with such a poisonous thing?
How poisonous are castor beans?
Former U.S. President Donald Trump should be familiar to everyone, right?
Once, he was almost assassinated with castor!
It happened that on September 19, 2020, Trump suddenly received a letter from the White House.
Fortunately, the first person to get the letter was an experienced security officer, and after the security officer got the letter, he keenly noticed that the letter might be wrong, so he handed the letter to the professional testing department for testing.
The results of the test showed that there was indeed something wrong with the letter, and ricin was detected inside.
If Trump hadn't paid attention and opened the letter without any protection, he would have been poisoned and died......
Letter to Trump
The ricin here is extracted from castor beans.
Ricin is a cytotoxic genre.
It is composed of the combination of two chains, A and B, after entering the human body, the two chains will separate, and the B chain will combine with the cell surface, and then invade the cell, opening a "channel" for the A chain, helping the A chain to penetrate the cell membrane more easily into the cytoplasm, after the A chain enters the cytoplasm, it will begin to play a role, so that the ribosomes in the cell are inactivated, so as to achieve the purpose of inhibiting protein synthesis, and eventually lead to the death of the cell.
Ricin is divided into A and B chains
Poisoned people will show different symptoms depending on the way ricin is ingested.
For example, people who are poisoned by inhalation will mainly have lung problems and may eventually die of lung failure, those who are poisoned by food will have digestive problems and may eventually die of multi-organ failure, and those who are poisoned by injection will have problems such as blood fever and may eventually die of blood poisoning.
Ricin causes red blood cell agglutination (left and center), normal red blood cell state (right)
If Trump had opened the letter, perhaps he would have died of lung failure from inhaling ricin.
The most important thing is that ricin is very toxic, and the most toxic grade D ricin can easily kill an adult with only 0.2 mg.
Therefore, this toxin is widely used in assassination, and it is the most popular toxin among killers after cyanide......
Castor is so poisonous, why are countries still rushing to ask for it?
It is said that the bigger the wind and waves, the bigger the fish, and the same is true for castor.
Although castor beans are poisonous, their value in other areas should not be underestimated.
In the medical field, ricin can be used in the treatment of cancer, and as Okawa mentioned earlier, ricin can disintegrate normal cells in the human body, and in this case, it has the same disintegrating function for cancer cells.
Therefore, in the medical field, ricin is often used to inhibit the growth of cancer cells such as lymph node cancer.
In agriculture, ricin is also often used to eliminate pests such as snails, and the effect is very significant.
Of course, its value in the industrial field should not be underestimated, and the United States regards it as a strategic material based on its role in the industrial field.
Castor beans contain a lot of oil, which is different from our common vegetable oils when squeezed out, and has excellent characteristics such as high viscosity and low freezing point.
Therefore, it can be used in the processing of lubricants and engine oils for machinery and equipment.
For now, the biggest problem with castor beans is its yield.
In China alone, the demand for castor beans is as high as 400,000 tons a year, and the rest of the world also needs it, but the problem is that its production is too low.
Research data show that the perennial planting area of castor in the mainland is only about 3 million mu, and the output is even more pitiful, so we have to hope that a large number of high-quality castor beans are imported from India and other countries every year.
At present, the key to solving this problem lies in how to increase the yield of domestic castor beans and how to improve the quality of domestic castor.
Only by solving these problems can the mainland truly realize the freedom of castor, and even realize the export of castor......
