What is Ricin?
Ricin is a natural substance that stops cells from making the proteins they need to live. Imagine your body's cells are like tiny factories. Ricin comes in and shuts down the machines that build new parts for the factory. When cells cannot make these important proteins, they stop working and eventually die.
Where Does Ricin Come From?
Ricin is found in the seeds of the castor oil plant. This plant grows in many warm parts of the world. While castor oil, which is used in some medicines and products, is made from these seeds, the ricin is removed during the process. This makes the oil safe to use. However, the raw seeds themselves are very dangerous if eaten.
How Does Ricin Harm Living Things?
Ricin works by getting inside the cells of the body. Once inside, it targets the ribosome, which is like the protein-making machine in a cell. Ricin stops the ribosome from doing its job. Without new proteins, cells cannot repair themselves or grow, and they start to die. This can cause serious damage to many parts of the body.
Why is Ricin Dangerous?
Ricin is very dangerous because it can harm the body in many ways, depending on how it gets inside. If someone breathes it in, it can damage the lungs. If it is swallowed, it can hurt the stomach and intestines. Because it is so powerful and can be very harmful, ricin is considered a serious threat. It is important to know that castor beans should never be eaten or handled without proper safety measures.
