气味苦，微寒，无毒。主治皮肤热，大腹水气，四肢面目浮肿，丈夫阴气不足。
（泽漆《本经》名漆茎，李时珍云∶《别录》、陶氏皆言泽漆是大戟苗。日华子又言是大
戟
花，其苗可食。然大戟苗泄人，不可为菜。今考《土宿本草》及《宝藏论》诸书并云∶泽漆
是猫儿眼睛草，一名绿叶绿花草，一名五凤草。江湖原泽平陆多有之，春生苗，一科分枝成
丛，柔茎如马齿苋，绿叶如苜蓿叶，叶圆而黄绿，颇似猫睛，故名猫儿眼。茎头凡五叶中分
，中抽小茎五枝，每枝开细花，青绿色，复有小叶承之，齐整如一，故又名五凤草，绿叶绿
花草。茎有白汁黏人，其根白色，有硬骨，以此为大戟苗者，误也。据此则泽漆是猫儿眼睛
草，非大戟苗也。今方家用治水蛊、香港脚有效，尤与《神农》本文相合，自汉人集《别录》
，误以名大戟苗，故诸家袭之尔。）
（愚按∶泽漆与大戟同类，而各种用者，须知之。）
（李时珍曰∶泽漆利水功类大戟，人又见其茎有白汁，遂误以为大戟，大戟根苗皆有毒
泄人，而泽漆根硬，不可用
苗，亦无毒，可作菜食，而利丈夫阴气，甚不相侔也。）
泽漆五枝五叶，白汁白根，禀金土之精，故能制化其水，盖金生水而土制水也。气味苦
寒，
故主治皮肤热，土能制水，故治大腹水气，四肢面目浮肿，金能生水，故治丈夫阴气不足。
《金匮》有泽漆汤，治咳逆上气，咳而脉浮者，浓朴麻黄汤主之，咳而脉沉者，泽漆汤主之
。
【气味】味苦，性微寒，无毒。
【主治】皮肤发热，大腹水气病，四肢及面目浮肿，男子阴气不足。
（泽漆在《神农本草经》中名为“漆茎”。李时珍说：《名医别录》和陶弘景都记载泽漆是大戟的幼苗。日华子又说它是大戟的花，其苗可以食用。但大戟的苗会泄人正气，不能作为蔬菜。现在考证《土宿本草》及《宝藏论》等书籍都说：泽漆是猫儿眼睛草，又名绿叶绿花草，又名五凤草。在江湖、原野和平地多有生长，春天生苗，一科分枝成丛，柔嫩的茎像马齿苋，绿色的叶子像苜蓿叶，叶片圆而黄绿色，很像猫的眼睛，所以名叫猫儿眼。茎头通常五片叶子从中分开，中间抽出五根小茎，每根小茎开细小的花，青绿色，下面有小叶托着，整齐如一，所以又名五凤草、绿叶绿花草。茎中有白色汁液粘人，根部白色，有硬骨。认为它是大戟幼苗的人，是错误的。根据这些记载，泽漆是猫儿眼睛草，不是大戟的幼苗。如今医生用它治疗水蛊病、脚气病有效，尤其与《神农本草经》本文相符。自从汉代学者汇集《名医别录》，错误地将其命名为大戟幼苗，所以各家沿袭了这个说法。）
（我按语：泽漆与大戟同类，但各种用途不同，需要知晓这一点。）
（李时珍说：泽漆利水的功效类似大戟，人们又看到它的茎有白色汁液，于是误以为它是大戟。大戟的根和苗都有毒，会泄人正气；而泽漆根硬，不可用苗，也没有毒，可以作为蔬菜食用，且能补益男子的阴气，两者相差甚远。）
泽漆有五枝五叶，白色汁液白色根，禀受了金和土的精华，所以能够制约和转化水湿。大概是因为金生水而土制水。气味苦寒，所以主治皮肤发热；土能制水，所以治疗大腹水气、四肢面目浮肿；金能生水，所以治疗男子阴气不足。
《金匮要略》中有泽漆汤，治疗咳嗽气逆上冲，咳嗽且脉浮的，用厚朴麻黄汤主治；咳嗽且脉沉的，用泽漆汤主治。
[Taste and Nature] Bitter, slightly cold, non-toxic.
[Indications] Skin heat, abdominal water retention (ascites), edema of the four limbs and face, insufficiency of Yin-Qi in men.
(Zeqi was named "Qijing" in the *Shennong Bencao Jing*. Li Shizhen stated: Both the *Bielu* and Tao Hongjing recorded that Zeqi is the seedling of Daji. Ri Huaizi further stated it is the flower of Daji, and its seedlings are edible. However, Daji seedlings purge the body's Qi and cannot be used as vegetables. Current examinations of texts such as *Tusuxingbencao* and *Baocanglun* indicate: Zeqi is *Euphorbia helioscopia*, also known as "Cat's Eye Grass," "Green Leaf Green Flower Grass," or "Five Phoenix Grass." It grows abundantly in rivers, lakes, plains, and dry land. Seedlings emerge in spring; one cluster branches into a tuft. The tender stems resemble those of *Portulaca oleracea* (Purslane); the green leaves resemble those of *Medicago sativa* (Alfalfa). The leaves are round, yellowish-green, resembling cat eyes, hence the name "Cat's Eye." Typically, five leaves branch from the stem tip, with five small stalks emerging from the center. Each stalk bears tiny flowers, bluish-green, supported by small leaves below, arranged neatly and uniformly, hence the names "Five Phoenix Grass" and "Green Leaf Green Flower Grass." The stems exude a white, sticky juice. The roots are white and hard-boned. Those who claim it is a seedling of Daji are mistaken. Based on this, Zeqi is Cat's Eye Grass, not a seedling of Daji. Currently, physicians use it effectively to treat hydroperitoneum (water gu) and podagra/foot qi, which aligns well with the original text of the *Shennong Bencao Jing*. Since Han dynasty scholars compiled the *Bielu*, erroneously naming it a seedling of Daji, subsequent authorities have followed this error.)
(My commentary: Zeqi belongs to the same category as Daji, but their various applications differ; this must be understood.)
(Li Shizhen said: Zeqi's diuretic function is similar to that of Daji. People see the white juice in its stems and mistakenly identify it as Daji. The roots and seedlings of Daji are toxic and purgative, whereas Zeqi has hard roots, its seedlings should not be used medicinally, are non-toxic, can be eaten as vegetables, and can benefit the Yin-Qi of men. The two are vastly different.)
Zeqi has five branches and five leaves, white juice, and white roots. It inherits the essence of Metal and Earth, thus enabling it to control and transform Water. Generally speaking, Metal generates Water, while Earth controls Water. Due to its bitter and cold nature, it treats skin heat. Because Earth controls Water, it treats abdominal water retention and edema of the limbs and face. Because Metal generates Water, it treats insufficiency of Yin-Qi in men.
The *Jin Gui Yao Lue* contains Zeqi Tang, indicated for cough with rebellious Qi ascending. For cases where cough is accompanied by a floating pulse, Houpo Mahuang Tang is the primary formula; for cases where cough is accompanied by a deep pulse, Zeqi Tang is the primary formula.
