蓖麻毒素是一种来自蓖麻子的致命毒药。 一粒沙大小的剂量足以杀死人。 毒素通过使核糖体失活并停止蛋白质生产而起作用，这最终是一个致命的问题。 没有毒药的解毒剂，但如果剂量足够小则可以生存。 蓖麻毒素在1978年被用来暗杀保加利亚人格奥尔基·马尔科夫。虽然您不太可能会遇到纯化的毒药，但在蓖麻植物的种子中发现了这种毒素。 吞下整个种子不会使您中毒，但儿童和宠物应远离看起来有趣的豆类，因为咀嚼它们可能释放出足够的毒素而造成伤害。
Ricin is a deadly poison from ricin. A sand-sized dose is enough to kill a person. Toxins work by inactivating ribosomes and stopping protein production, which is ultimately a fatal problem. There is no antidote for poison, but it can survive if the dose is small enough. Ricin was used in 1978 to assassinate Bulgarian personality Olki Markov. Although you are unlikely to encounter purified poison, this toxin has been found in the seeds of the castor plant. Swallowing whole seeds won’t poison you, but children and pets should stay away from beans that look interesting because chewing them can release enough toxins and cause harm.
