Castor beans are filled with ricin.
蓖麻籽富含蓖麻毒素。

The good: Castor oil is used in a number of ways, usually by parents for their kid's stomach aches. You can also find the oil in food flavorings and colorings, such as in candy and chocolate.
益处：蓖麻籽油具有多种用途，父母一般会用作孩子的胃药。你也可以在食品调味剂和调色剂中找到这些东西，如糖果和巧克力。

The bad: Just one castor bean is enough to kill a child, and a few more can kill an adult. A single gram of ricin, the bean's main toxin, is thousands of times more powerful than cyanide. Worst of all, there is no known remedy for a ricin poisoning.
坏处：一粒蓖麻籽就能杀死一个儿童，成年人多吃几粒也会死去。一克蓖麻毒素毒效等于氰化物的上千倍。最糟糕的是，现在还没有针对这种毒素的药方。
