寇宗奭说：叶子像小杏叶，但更薄且绿色较淡。果实八月、九月成熟，初为青色后变黑，分为三瓣。

[Euodia Fructus / White Barked Euodia] (Pronunciation: Liang Ren Qie. From *Bencao Shiyi*).
[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.
Ash of Euodia Wood
[Properties and Flavors] Sweet, Warm, slightly toxic.
[Indications] Sudden onset of abdominal masses (Zhen Jia), hardness, fullness, and fixed accumulations (Pi Ji). Extract eight sheng of juice from Euodia leaves, ferment with one dou of rice. Once the wine is ready, take half he in warm liquid each time, gradually increasing to one or two zhan, until cured (Chen Zangqi, from *Zhou Hou Bei Ji Fang*).
[Chinese Tallow Tree] (From *Bencao Shiyi*).
[Names] Mu Nu.
[Collected Explanations] Chen Zangqi stated: According to *Guang Zhi*, Chinese Tallow grows in the valleys of southern Guangxi. Persians use its wood to build boats.

[Properties and Flavors] Pungent, Neutral, slightly toxic.
[Indications] Abdominal dropsy (Da Fu Shui Bing). Collect bark, boil in water, remove dregs, and decoct until it can be formed into pills the size of Sophora seeds. Take three pills on an empty stomach at dawn, and one pill shortly after. Qi and water will discharge through urination (Chen Zangqi).
[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.
White Bark of Black Euodia Root
[Properties and Flavors] Bitter, Slightly Warm, Toxic.
Meng Shen stated: Nature is Cool; use only after slow-fire roasting until yellow.
[Indications] Sudden edema, pathological accumulations and masses (from *Tang Bencao*).
[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.
