Artemisia Plant (Liu Ji Nu)

Diverse Wormwood HerbThe Chinese name of artemisia is Liu Ji Nu, which was originally the childhood name of Liu Yu (363–422), the founding emperor of the Chinese dynasty Liu Song. This is the only Chinese herb that is named after an emperor. Actually how it was found is related to an interesting story.

One day when little Liu Yu went up to the mountains for cutting firewood, he came across a giant snake. He broke out in a cold sweat and in haste grabbed the bow and arrow to shoot it in the head. Then the snake fled wounded. The next day he went into the hills again and out of the distance came a pounding sound that was quite faint. He followed the sound and found that two boys in green were pounding medicine. Then he came up and asked: “Whom are you pounding medicine for? And what is it for?” The boys replied: “Our king was shot by Ji Nu yesterday and now we are sent to gather herbs for his wound.” Liu Yu heard and roared to them: “I am Liu Ji Nu and coming for you.” These two boys were so scared that they escaped and left the medicine. And the rest is a history.
