There is a seed in gardens across America that looks like a polished gemstone. Beautiful enough to wear as jewelry. Shiny, modeled, brown, and [music] cream. Perfectly oval. Children pick them up thinking they found treasure in the backyard. One to three of those seeds [music] can kill a child. Four to eight can kill an adult. Not in days, not in weeks, within 72 hours. This is Caster Bean, Rino's communist. You are watching forgotten soil. We reveal the poisonous plants [music] hiding in plain sight. Disguised as food. Every episode we expose one more deadly mimic. If you want to stay safe, subscribe now. This is today's warning. Caster bean grows in [music] public parks, in elementary school gardens, along hiking trails, and in suburban backyards from Florida to California. It reaches 3 m tall in a single summer. Leaves the size of dinner plates. Seed pods covered in [music] soft spines. The plant produces hundreds of seeds per season. Each one capable of stopping a human heart if the outer shell breaks. [music] You have walked past this plant. Your children have played near it. Most people call it tropical, dramatic, ornamental beauty. Nurseries sold it for decades before Florida banned the sale in 2001. It still grows wild where it escaped. The seeds do not look dangerous. That is precisely the problem. They look like something you would string into a necklace. Smooth, heavy for their size. A marbled pattern unique to each seed. Some people actually do make jewelry from them. The seed coat is so hard that if you swallow one hole, it passes through your body without releasing the poison. But if a child bites down thinking it is a nut, if the shell cracks even slightly, the toxin floods out, that toxin is Ryson, 6,000 times more poisonous than cyanide. One of the deadliest substances known to science. The archive opens in 1978. London, a bus stop. A man waiting in line for the morning commute. Georgie Marov, Bulgarian journalist. Defector. He felt a sharp sting in his thigh like an insect bite or thorn prick. He looked down, saw nothing unusual. A stranger with an umbrella walked away quickly into the crowd without apologizing or stopping. 5 hours later, Marov began feeling weak. By evening, he developed a fever. The next day, the fever continued and worsened. Within 36 hours he was in hospital. Fever, rapid heart rate, swollen lymph nodes. Doctors could not identify the cause. On the third day, his blood pressure dropped. His organs began shutting down. He died 72 hours after that sting. The autopsy found a tiny metal pellet embedded in his thigh, smaller than a pin head, containing approximately 500 microgram, 500 microgram of Ryson. delivered through the tip of a modified umbrella, an assassination method from cold war intelligence agencies. This was not fiction. This was not theoretical bioteterrorism. This was a plant toxin harvested from seeds you can find in gardens. But most rice and poisoning does not involve spies or umbrellas. It involves children, gardens, and a deadly misunderstanding about castor oil. Castor oil, the laxative your grandmother knew. extracted from these same seeds [music] used safely for thousands of years in medicine and cosmetics. People see castor oil in drugstores [music] and assume the plant must be harmless. That assumption has killed people across four [music] continents. Ancient Egyptians used castor oil in lamps and eye treatments 4,000 years ago. The seeds [music] were found in tombs. India produces 75% of the world's castor oil today, over 1 million tons annually. It lubricates engines, waterproofs fabric. The oil is extracted through heating and pressing. The heat destroys [music] ryson. The pressing separates it. The oil contains zero toxin. But the seed itself, the whole untreated seed contains 1 to 5% ryson [music] by weight and the pulp inside that shell. So what does Ryson actually do inside a human body? Let me show you the mechanism that makes it unstoppable. Ryson is a protein. Two chains linked together. The B chain binds to cells throughout your body. The A chain enters those cells. Once inside, the A chain attacks ribosomes. Ribosomes are the machinery that builds every protein your cells need to survive and function. One molecule of Ryson can destroy 1,500 [music] to 2,000 ribosomes per minute. A single molecule reaching the cell interior kills it. Your cells cannot make proteins. They cannot repair themselves. They cannot perform any function. They die. Your tissues start breaking down. The intestinal lining sheds. The liver cells rupture. The kidneys fail. Blood vessels leak. Your organs disintegrate at the cellular level. But here is what nobody tells you. Here is the cruelty that Ryson victims describe before they lose consciousness or speech. There is a delay. four to 6 hours on average after you chew and swallow those beautiful seeds before symptoms appear, you feel fine. You tell people you feel fine. You might even forget you ate anything unusual that morning or afternoon. Then the nausea hits, vomiting, abdominal pain that feels like your stomach [music] is tearing itself apart from the inside out. By the time you realize something is catastrophically wrong, the Ryson has already bound to millions of cells throughout your body. It is already inside those cells already destroying ribosomes already making it impossible for your body to repair the damage. Ancient healers did not have the word ribosome. They did not need one. They knew these seeds killed slowly. Inevitably, agonizingly, they knew that once symptoms started, all you could do was watch, hydrate, hope, pray the dose was small enough, because 2,000 years later, we still cannot do much more than that. So, here's the question nobody wants to answer. If this toxin has no antidote and kills reliably within days, why do caster bean plants grow in parks and gardens? The answer is not conspiracy. The answer is a gap between what scientists know [music] and what the public assumes is safe. Let me walk you through what happens when someone swallows caster beans. What can save them? What cannot? What never will? A child finds three seeds under a caster plant in the backyard. They look like fancy beans. She cracks one open with her teeth. Here is the precise moment where everything that happens next becomes a race against cellular destruction that has already begun. Insider 1990 medical literature review. 424 documented caster bean poisoning cases analyzed. 14 died. 3% mortality overall, but separate those cases by treatment. 8% died without medical intervention. 0.4% 4% died with hospital care. You cannot cook the poison out. Ryson remains stable at temperatures above 80° C for extended periods. You cannot induce vomiting safely. The toxin absorbs through the stomach lining within hours. Vomiting causes aspiration risk without removing Ryson. You cannot wait for symptoms to confirm poisoning. Liver damage begins before you feel anything. Treatment must start during that silent window. You cannot trust plant identification apps alone. Seeds look similar to certain nuts. The cost of misidentification is a child's life. You cannot rely on the hard seed coat for protection. Children bite harder than adults assume. One crack releases the poison. 4 to 6 hours after ingestion, the first wave hits. Nausea, vomiting, diarrhea. Some victims describe it as the worst food poisoning imaginable. But this is not food poisoning. This is your intestinal lining beginning to slough off in sheets. Blood appears in the vomit. 6 to 12 hours. Dehydration accelerates. The body loses fluids faster than most people can replace them at home without intravenous support. 12 to 24 hours. Kidneys start failing. Liver enzymes spike. Blood sugar drops. Children deteriorate faster than adults because of their size. 24 to 72 hours. This is where [music] deaths occur. Hypoalmic shock. Cardiovascular collapse. Multiple organ failure. Seizures. Coma. If you survive [music] past 72 hours, full recovery is typical. No lasting damage in most cases. But reaching 72 hours requires hospital intervention. Here is what hospitals can do. Activated charcoal if you arrive within 4 hours. Introvenous fluids. Electrolyte replacement monitoring. Supportive care. Here is what they [music] cannot do. Stop the ry that is already inside your cells. Reverse the ribosome destruction. Give you an antidote. There is no antidote. Experimental vaccines exist in phase one trials. They are preventive, not treatment. They do not save you after exposure. The cruelty is in knowing exactly how Ryson kills at the molecular level, but having no way to interrupt that mechanism. But here is what you can do. Here is what separates the 99.6% who survive from the 4% who do not. [music] Recognition, speed, immediate action. Every minute between ingestion and medical care [music] increases the percentage of ryson absorbed into the bloodstream and tissues. 2024 Belgium. A 47year-old woman ingested six caster beans. She reached the hospital while still asymptomatic within hours. Gastric decontamination. Activated charcoal. 3 days of monitoring and introvenous hydration. Complete recovery. She went home. She lived because she acted fast. 2011. Oman. A 51-year-old man swallowed one caster bean thinking it would cure his cough. Traditional remedy. Catastrophic error. 3 hours later he became confused, disoriented, pupils dilated, heart rate dropped. 2 days in hospital. He survived because one seed because quick treatment. But look at why these poisonings keep happening every year. Different countries, different circumstances, same deadly plant, same preventable mistakes. Children mistake seeds for treasure. Adults mistake folk wisdom for medical advice. Gardeners mistake ornamental beauty for harmless decoration in the landscape. So, here is how you identify a caster bean before anyone in your family picks up those seeds and makes the fatal assumption. The plant itself is unmistakable once you know what to look for. Leaves shaped like giant outstretched hands, 5 to 11 pointed loes, glossy, waxy [music] surface, often red veins. The leaves can reach 70 cm across, bigger than any native plant in most American gardens. But the [music] definitive identifier is the seed pod. Spiny spherical capsules, soft, flexible spines. They look like small green chestnuts covered in rubber spikes. [music] Inside each capsule are three seeds. When the capsule splits open in late summer, those seeds drop to the ground beneath the plant. The seeds are 1 to 2 cm long, oval, shiny, modeled brown, and cream and patterns unique to each seed like fingerprints. There is a warty bump on one end called a caruncle. This is the definitive marker. [music] No edible seed has this structure. If you see this plant in a yard where children play. Do not wait. Do not assume the homeowner knows what they planted. [music] Wear heavy gloves. Cut it at the base before it produces seeds. Bag every part, especially the seed pods and seeds themselves. [music] If a child puts a caster seed in their mouth, call poison control immediately. 1-8002221222. Do not wait for symptoms. Do not induce vomiting. Do not give them water or milk. Call. Tell them caster bean. Tell them how many. The poison control center will tell you whether to go to the emergency room or monitor at home. Most cases require hospital evaluation. Every parent who learns to identify this plant is one more family who will not bury a child because of a shiny seed. The seed they thought was a pretty pebble. The plant they thought was just tropical decoration. The remedy they thought was traditional medicine passed down through generations of healing knowledge and cultural wisdom. Gorgi Marov knew his enemies wanted him dead. The child picking up seeds does not know anything is wrong. The man seeking a cough cure trusted his ancestors. Now you know what all of them learned too late. Caster bean is still here. Still growing in gardens and along roadsides and in parks. Still producing hundreds of those beautiful modeled seeds every fall. Still waiting for the next person who assumes beauty means safety. One seed can kill a child.
