，与细锉海芋叶拌蒸，从巳至申，去芋叶，晒干用之。太上八帝玄变经大戟必泻。
味苦、甘，性寒至大寒，有小毒。主治蛊毒，各种水肿病（十二水），腹部胀满急痛及积聚症，中风引起的皮肤疼痛，呕吐逆气，颈部和腋下的痈肿，头痛；具有发汗、通利大小肠的功效。又名邛钜。生长在常山。十二月采集根部，阴干。（与甘草相反。）
陶隐居说：附近道路两旁到处都有。非常低贱。臣禹锡等谨按《唐本草》记载：畏惧菖蒲、芦草、鼠尿。《蜀本草》和《图经本草》记载：苗像甘遂一样高大硕壮，叶子有白色汁液，花黄色。根像细苦参，皮黄黑色，肉黄白色。五月采集苗，二月、八月采集根部使用。《尔雅》说：荞，即邛钜。注释说：现在的本草中大戟就是这种药。《药性论》说：大戟为佐使药。与芫花、海藻相反，用菖蒲解其毒。味苦、辛，有大毒。破除新旧瘀血，排出恶血癖块，腹内雷鸣般作响，通调月经，善于治疗瘀血，能导致流产。日华子说：小豆为之使，厌恶薯蓣。泻解毒药，泄除天行黄病、温疟，破除症结。
《图经本草》说：大戟，是泽漆的根。生长在常山，现在附近道路多有生长。春天生出红芽，逐渐长成丛状，高一尺左右。叶子像初生的杨柳小团。三月、四月开黄紫色花，团圆像杏花，又像芜荑。根像细苦参，皮黄黑色，肉黄白色，秋冬采集根部，阴干。淮甸出产的茎圆，高三四尺，花黄色，叶心也像百合苗。江南生长的叶子像芍药。医家用它治疗隐疹风，以及风毒脚肿，并煮水热淋，一天多次服用就会痊愈。李绛《兵部手集方》：治疗水肿病，不论年月深浅，即使脉象恶劣也主治此病。大戟、当归、橘皮各一大两切碎，用水二大升，煮取七合，一次性服用。利水二三斗，不要奇怪。病情严重，不过再服用一次就会好转。禁食毒物一年，水退后继续服用，永不复发。此方出自张尚客。
雷公说：凡使用，不要用新鲜生用的，如果服用后冷泄气不禁，就用煎荠子汤解救。采得之后，在槐木砧板上细细切碎，与切碎的海芋叶拌蒸，从巳时到申时，去掉芋叶，晒干使用。《太上八帝玄变经》说大戟必定泻下。
Euphorbiae Pekinensis Radix (Daji)
Bitter, sweet; cold to very cold; slightly toxic. Primarily treats gu poison (parasitic poisoning), twelve types of edema (shiershui), abdominal distension with acute pain and accumulations, skin pain due to wind-stroke, vomiting and regurgitation, carbuncles and swellings in the neck and axilla, headache; induces sweating, promotes urination and bowel movements. Also known as Qiongju. Grows in Changshan. Harvest roots in the twelfth lunar month, dry in shade. (Incompatible with Glycyrrhizae Radix et Rhizoma [Gancao].)
Tao Hongjing stated: It is found everywhere along nearby roads. It is extremely common and cheap. Ministers Yuxi et al. carefully noted according to *Tang Bencao*: It fears Acori Tatarinowii Rhizoma (Changpu), Phragmitis Rhizoma (Lugao), and rat urine. *Shu Bencao* and *Tujing Bencao* record: The seedling resembles Euphorbiae Kansui Radix (Gansui), tall and robust; leaves contain white latex; flowers are yellow. The root resembles Sophorae Flavescentis Radix (Xiku Shen); bark is yellow-black, flesh is yellow-white. Harvest seedlings in the fifth lunar month, harvest roots in the second and eighth lunar months for use. *Erya* states: Qiao, i.e., Qiongju. The annotation states: This is the Daji in current materia medica. *Yaoxing Lun* states: Daji acts as an assistant or envoy herb. Incompatible with Genkwanis Radix (Yuanhua) and Sargassum (Haizao); its toxicity is resolved by Acori Tatarinowii Rhizoma (Changpu). Bitter, pungent; highly toxic. Breaks down new and old blood stasis, expels evil blood and masses, causes rumbling in the abdomen, regulates menstruation, excels at treating blood stasis, can induce abortion. Ri Huazi stated: Adzuki Bean (Xiaodou) acts as its guide; it dislikes Dioscoreae Rhizoma (Shuyu). It purges toxic substances, clears Tianxing jaundice, warm malaria, and breaks down fixed masses.
*Tujing Bencao* states: Daji is the root of Phyllanthi Defini Herba (Zeqi). It grows in Changshan and is now abundant along nearby roads. In spring, red buds emerge, gradually growing into clumps about one chi high. Leaves resemble small clusters of young willow shoots. In March and April, yellow-purple flowers bloom, round like apricot blossoms, resembling Meliosmae Fructus (Wuyi). The root resembles Sophorae Flavescentis Radix (Xiku Shen); bark is yellow-black, flesh is yellow-white. Harvest roots in autumn and winter, dry in shade. Those from Huaidian have round stems, three to four chi high, yellow flowers, and leaf centers resembling Polygonati Rhizoma (Bahe) seedlings. Those growing in Jiangnan have leaves resembling Paeoniae Radix Rubra (Shaoyao). Physicians use it to treat hidden rashes and wind-pathogens, as well as wind-toxic swollen feet, and boil water for hot strangury; taking it multiple times a day leads to recovery. Li Jiang's *Bingbu Shouji Fang*: Treats water diseases, regardless of duration; even if the pulse is unfavorable, it is indicated. Daji, Angelicae Sinensis Radix (Danggui), and Citri Reticulatae Pericarpium (Jupi), each one da liang, chopped; decoct in two da sheng of water until seven he remains; take in one dose. It will promote the discharge of two to three dou of water; do not be surprised. For severe cases, no more than one additional dose is needed for improvement. Avoid toxic foods for one year; after water recedes, continue taking it to prevent recurrence permanently. This prescription comes from Zhang Shangke.
Lei Gong stated: When using, do not use fresh/raw material. If taken and causes cold diarrhea with inability to retain qi, resolve it by decocting Descurainiae Semen Lepidii Semens (Qizi) soup. After harvesting, finely chop on a locust wood cutting board, mix with finely chopped Arisaematis Cum Bile (Haiyu Ye - note: text says Haiyu leaf, likely referring to a specific preparation context or typo for another herb, but translated literally as Arisaema leaf), steam from Si hour to Shen hour, remove the Arisaema leaves, dry in the sun for use. *Taishang Badi Xuanbian Jing* states that Daji inevitably causes purgation.
