For adults, only 1 mg of ricin or 160 mg of ephedrine is required。
Such severe toxicity is not an exaggeration, but is derived from the bulletin on the prevention of incidents of food intoxication due to eating leprosy seed issued by the national commission for health and health in 2006。
Why is the ricin so violent? In short, toxins interfere with protein synthesis, causing cells to be unable to sustain normal activity, causing a high number of deaths within two to three days and spreading to organs such as the liver, kidneys, spleen and lungs, with the ultimate cause of death being “organ failure”。
The most common form of poisoning is oral, with children eating between 1-2 ricin seeds and adults eating between 3-12 grafts leading to severe poisoning or death
Most strongly, chewing, boiling (shortly) or baking do not completely destroy the ricin toxin, which used to grow in rural areas, where many thought that cooking would remove the toxicity and eventually lead to poisoning deaths。
A lot of ricin
If the ricin is so poisonous, why do you have to grow it so much? To understand whether it's easy to grow mainly by looking at two points? Can value be produced
The ricin is very drought-resistant, adapts to sandy, border and gravel soil, with roots at a depth of 2-3 metres, extracts deep moisture and survives in soil at 4. 5 ~ 8. 5 ph, with little need for fertility, except in parts of china that are cold and deserts, but where there is a little sip in the soil, the ricin survives。
It is easy to see ricin in the wasteland without manual care, and it is rich in toxins, with few common pests and pests, and is not easily eaten by cattle and sheep。
After 70 and 80, it should be recalled that since the 1950s, when we planted large quantities of ricin and were acquired by a single sales agency, why is there such a culture
Because fibres can be extracted from the plume, they can make ropes, paper and high-density plates, they are high-quality industrial raw materials, they can be used to feed the plume, they can harvest high-quality textile raw materials, and they can be fed to pigs after detoxification of the plume, which was a rare high protein feed。
So the reason for the high level of ricin cultivation is that ricin is easy to grow, has a high output and is economically efficient。
Strategic goods
The most valuable thing about ricin oil is that it contains 46%-55% of the oil and is referred to as "oil from the land"。
It has strong temperature stability, does not coagulate at 18°c, does not burn at 500°600°c, is well suited for use as motor lubricant for aerospace, has the advantage of stabilizing mobility, protection against wear and tear, and can be used as hydraulic fluid for missiles, brake oil for military vehicles, etc。
Most valuable of all is the amount of ricin in ricin, which is as high as 80 ~ 90 %, the chemical reaction activity is extremely high, and the key intermediates, i. E., diicin, cortisol and so forth, are, by humans, important ingredients for more than 3,000 products, covering the entire industrial system。
So ricin oil is indispensable for a country's aerospace, military, high-end manufacturing industries, etc。
United states demand for ricin oil is about 460,000 tons per year, but since the 1970s the united states has ceased to grow ricin and is totally dependent on imports, mainly from india, brazil and china。
Taking into account uncertainties such as trade frictions and geo-conflicts, the united states officially included ricin oil in the agricultural materials act 1984 as "strategic goods essential to national defence"。
