The story of Chaihu is told long ago, an old landlord, a rich man, hired two long-term workers named Chai and Hu. The two long-term workers call each other brothers. One day, Hu Di suddenly got a strange disease, fever for a while, and chills for a while. The cruel landlord actually dismissed the sick Hu Di and expelled him from the house.
Brother Chai was very angry and asked the landlord to complain, but the landlord ignored it. Brother Chai was so angry that he picked up Brother Hu and left. At the foot of a mountain, Hu Di could not walk, lying on the ground. Brother Chai went to find wild fruits to satisfy his hunger. Hu Di was hungry and unbearable. He randomly pulled out a kind of grass with bamboo leaves and chewed on the ground. Soon after eating the grass roots, Hu Di felt much more relaxed. When Brother Chai came back, he was surprised to find that Hu Shiling's fever was better! Brother Hu told Brother Chai about eating grass roots.
Both Brother Chai and Brother Hu believed that this kind of wild grass must be a medicine, so they dug some and brought it back, decoctioning the poor people who suffered from cold and heat, but the effect was very good. This proves that this grass does have a curative effect. Since then, the two of them have used this grass to heal people and cured many people. To commemorate them, future generations called this herbal medicine "Chaihu", which continues to this day.
