 A poison can be thought of as any chemical substance that causes a harmful change in the body. Medically, it is hard to define a poison, because any cause illness, harm bodily functions, or cause death.

I read "Poison".  I could learn the types, mature, story, and history about poison. It was particularly impressive that poison was used first more that 4500 years ago, and it was used as poisoned spears and arrows for war. Moreover, the various toxic animal was introduced. For example, most poisonous frogs produce their venom from their skin. Some types of their venom contain enough poison to kill ten adult people. This face is so scared that human may be killed even such small animals. In conclusion, I could know the danger of poison again, and I wanted to know more about other poisonous creatures from now on.
