[Research on the changes of name of Wuzhuyu (Medicinal Evodia Fruit)].

The name of Wuzhuyu (Medicinal Evodia Fruit) comes from the place of "Wu", and the shape of its fruit, which is like a 'Zhuyu'. In addition, it is also called "Yi, Sha, Jiao, Dang, Yuejiao and Qiu" for different reasons; for example, "Yi" because of its processing and sacrificial function; and "Sha" because of the bug-killing function of its root and cortex. In Xin Xiu Ben Cao (Newly Revised Materia Medica) of the Tang Dynasty, its names were unified as Wuzhuyu. Because it can be eaten, it was also called "Shizhuyu". In the Song Dynasty, with the discontinued vogue of eating Zhuyu, people had difference attitudes to the "Wuzhuyu" and "Shizhuyu". Nowadays, "Wuzhuyu" is the established name of these kinds of materia medica.
