[Names] Mu (Pronunciation: Tan).
[Collected Explanations] Chen Zangqi stated: The Euodia tree grows in deep mountains of the Jiangnan region among large trees. There are several types of trees; those with dense leaves and large white flowers are used for medicine, while the ash from others is used by dyers.
Li Shizhen stated: This wood is the hardest, known as "Jin Mu" (Fiber Wood) by carpenters. The wood is used for dyeing crimson, and the leaves can also be used to brew wine.

[Black Euodia] (From *Tang Bencao*)
[Names] Wu Jiu.
Li Shizhen stated: Crows like to eat its seeds, hence the name. Lu Guimeng's poem says: "Resting, I often lean on the shadow of the Crow Uncle; picking frequently, I see the heart of Shu Gu." This is correct. Shu Gu refers to Peony. Some say: When this tree ages, its roots rot blackly into a mortar shape, thus getting this name. Zheng Qiao in *Tong Zhi* claimed "Wu Jiu is Gui Liu," which is incorrect.
[Collected Explanations] Su Gong stated: It grows in the plains and marshes south of the mountains. The tree is several ren high, leaves resemble pear or apricot leaves. In May, small yellowish-white flowers bloom. Fruits are black.
Chen Zangqi stated: Leaves can dye soap color. Seeds can be pressed for oil, which burns very brightly in lamps.
Kou Zongshi stated: Leaves are like small apricot leaves but thinner and paler green. Fruits ripen in August and September, initially green then black, splitting into three valves.
Li Shizhen stated: It is abundant in southern plains and marshes. Now people in Jiangxi plant it, harvest seeds, steam them, extract fat to make candles for sale. The fat on the seed skin is superior to the kernel.

[Elucidation] Li Shizhen stated: The root of Black Euodia has a sinking and descending nature, Yin within Yin, promoting diuresis and unblocking the intestines, surpassing the efficacy of *Euphorbia pekinensis*. A rustic suffered from swelling and excess qi strength. He was instructed to dig this root, pound it, decoct in water, and drink one bowl. After several bowel movements, the illness subsided. Those with deficient Qi must not use it. This prescription comes from *Taiping Sheng Hui Fang*, stating its miraculous efficacy.
