Geranium is a lumpy substance made from the wounded fluid that accumulates between the bamboo joints after the parasitic geranium wasp bites the holes, and then dries and coagulates. However, since the natural production is very small, most of the bamboo forests are burned and the leachate that overflows after the heat is intense is solidified in the bamboo nodes. The story of Tianzhu Huang Legend has it that long ago, there were a hundred families living in peace and happiness deep in the Jing Mountain. One year, a strange disease suddenly became prevalent among the newly born babies here. Once the disease took hold of them, the babies were convulsing all over their bodies and their horns were reeling, so people sought help everywhere, but to no avail. A young man in the village was determined to visit a famous doctor to cure the strange disease. He heard that there was a miracle doctor in Wudaoxia who could cure this disease, so he brought dry food and went over the mountains with the stars and the moon to look for this famous doctor. When he arrived at Wudaoxia, he met an old man who was hunting firewood, and he said that the doctor had gone to Shuangtizhai in the past few days. The young man said goodbye to the old man and hurried to Shuangtizhai. He suffered a lot and finally climbed up to the double ladder fortress, but because of overwork, he fainted in the cave. When he woke up, he saw the firewood hunter he met in the woods. The young man hurriedly told the old man about the strange disease that the babies in their village were suffering from, and the old man smiled and took him to a bamboo forest. In the bamboo forest, the old man took out some lumps from the bamboo joints and asked him to take them back to the village. The young man was about to thank the old man when he found that the old man had disappeared. The young man could not help but exclaim: “What a miracle doctor!” The young man hurried back to the village and boiled a big pot of the herbs given by the divine doctor and fed the sick babies to drink, and the sick babies in the village gradually got better. People said that the herb was a gift from the gods and was taken from the bamboo, so they called the herb “Tianzhu Huang”.
