[Correction] Yuxi stated: Chen氏 (Chen Shi) argued that "Yu" refers to the flower of a herb and should not be attached to the Wood category. It is now transferred here.

[Names] Yujin (found in *Taiping Yulan*), Honglanhua (found in *Bencao Gangmu*), Zishuxiang (found in *Bencao Gangmu*), Cao Shexiang, Chumomo (Buddhist scripture term).

Song said: Xu Shen in *Shuowen Jiezi* stated: "Yu is a fragrant herb. Ten leaves form one strand; one hundred and twenty strands are piled up and boiled. Yuchang (a fragrant wine used for sacrifices) is the essence of flowers from hundreds of herbs, mixed and brewed into wine to summon spirits. It was offered by people from distant Yu lands, hence called Yu. Yu refers to present-day Yulin Commandery."

Li Shizhen said: The Han Dynasty's Yulin Commandery corresponds to the areas of modern Guangxi, Guizhou, and Xun, Liuzhou, Yong, and Bin prefectures. *Yitong Zhi* only records that Luocheng County in Liuzhou produces Yujin (Tulip), which is this plant. *Jin Guangming Jing* calls it Chumomo fragrance. This is the fragrance of the Yujin flower, which shares the name but differs in substance from the Yujin root used today. *Tang Shenwei Bencao* incorrectly included this flower under the entry for Yujin root. According to Zhao Gize's *Liushu Benyi*: The character "Chang" depicts rice in a vessel being stirred with a spoon. The character "Yu" contains "Jiu" (mortar), holding a jar placed on a table; "Chang" has decorations, symbolizing the five body parts. The vernacular form is written as "Yu". Thus, "Yu" implies crushing flowers to brew wine, not referring to a place name; the place name derived its name from this herb.

[Collection and Explanation] Canger said: Yujin grows in Daqin (ancient term for Rome or West Asia). It blooms in February and March, resembling Honglanhua. Flowers are harvested in April and May, yielding the spice.

Li Shizhen said: According to Zheng Xuan: Yu grass resembles orchids. Yang Fu's *Nanzhou Yiwu Zhi* states: Yujin originates from Bin Country. Locals cultivate it, first offering it to Buddha statues; after several days of wilting, it is harvested. Its color is bright yellow, resembling lotus buds wrapped in hibiscus flowers, and can be used to scent wine. Additionally, *Book of Tang* records: During Emperor Taizong's reign, the Jiapi Kingdom presented Yujin. Its leaves resemble Ophiopogonis Radix (Mendong); it blooms in September, resembling hibiscus, with purple-green petals. The fragrance spreads dozens of steps. It flowers but does not bear fruit; those wishing to cultivate it take the roots. These two accounts are largely consistent, differing only in flower color, suggesting different varieties. *Ancient Yuefu* states: "Among them is Yujin and Suhe incense," referring to this Yujin. Zuo Guipin of Jin wrote *Ode to Yujin*: "That fragrant strange herb, named Yujin. Crossing distinct regions, precious treasures come seeking. The aroma is intense, pleasing to the eye and heart. Virtue shines through fragrance, admired by virtuous persons."
