Could there possibly be another use for poison?

Hey guys, what's up? ;) I hope your doing well. In this entry I will talk about another very important use of poison. Can you guess what it is? Since poison can kill, what can you use it for? (No, I don't mean killing people, but you're on the right track.) Most people are afraid of poison because it is very dangerous, but humans found a way to benefit from it: Using poison to hunt.

The Poison Dart Frog is a very poisonous amphibian which is commonly found in South American jungles. It is one the most poisonous animals in the world. An adult Phyllobates Terribilis contains 1 milligram of poison, which is enough to kill between ten and twenty humans. You might be wondering, why do they call it "Poison Dart Frog"? Colombian Indians use the frog's poison to cover their darts with it and make them lethal. The blowpipe and darts are made by hand out of slivers of palm wood, hardened over a fire. These darts are commonly used on game such as deer, armadillos, and several species of large forest birds. Sometimes they were used in battles. The Émbera people are famous for their high accuracy with blowpipes. Since the poison is very lethal, 1 direct hit will kill the target very quickly.

How does this tribe extract the poison from the frog? The frog is first impaled on a sharp piece of wood, and then it is sort of cooked in fire. Blisters, which are full of poison, will start to emerge on the frog's skin. The darts are then rubbed against these blisters, and the poison will adhere to them. Curiously, this poison can be stored in the frog for years and will still affect its target. Even if the toxins are transferred to another surface, the poison is still very dangerous. (Dendro Works)

As I continue to post entries about this topic, my interest grows more and more. I hope you are liking it too, cheers. :)
