"The Qin dynasty is the main cold and heat evil, cold and damp wind, limb pain, water, and urination." It is said that "Qin 艽 can cure the wind, no question for a long time, and rushing through the body", "Qin 艽 飞 飞 山谷 山谷 ” , , , 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘 弘Good." Su Shi: "There are many rivers and rivers in Shaanxi Province. The roots are yellow and correct. They are one foot long and have different thicknesses. The branches are five or six inches high... In the middle of June, they bloom purple, like Gehua... Every spring and autumn roots dry."
