【别录列为下品】
夏季时，脉象在皮肤表层如钩状；冬季时，脉象在骨骼深层如营气运行。
【气味】味甘，性微寒，无毒。
【主治】主要具有调和脾胃（和中）、降逆下气的作用。
【考证】说：二月播种，藤蔓缠绕在篱笆和墙垣之间。叶子大如杯口，圆形而尖端，花朵有紫色和白色两种颜色，形状像小蛾子，有翅膀和尾状突起。豆荚生在花下，品种有十余种，有的长有的圆，有的像龙爪虎爪，有的像猪耳朵或刀镰，形态各不相同，都成串地结在枝条上。白露节气后，果实更加繁茂，如果秋热持续则不易生长，所以又名“雪眉”，因其同气相求，又名“凉衍豆”，俗称为“羊眼豆”，也是因为形状相似之故。嫩的时候可以作为蔬菜或茶料食用，老了就收获种子煮食。种子有黑、白、赤、斑四种颜色。入药只取白色的，豆荚壳虽然厚实，但种子颗粒粗圆为佳。
先父说：菽是五谷之一，秋天成熟时色泽洁白，气味甘甜芬芳。蕴含了土、金、水三行贯通连系肝、心、肾三脏的意义。因此是调和脾胃、降逆下气的药物。
又说：药势向右迁移而下降，自然能止住暑气、消除热邪，解除口渴、停止痢疾。
【按语】说：“扁”字谐音于“遍”，是门户开启的意象。若夏日脉在肤表，蛰伏的虫子将要离去，这是门户破损或开启的象征。“扁”又谐音于“遍”，嘉禾之菽，是水藏中的谷物。若冬日脉在骨中，蛰虫封闭门户，这是君子安居室内的象征。参考《永类钤方》。确立稳固即将坠落或破碎的胞胎，那么“坏户”与“启户”的意义，真是不用言语形容也清楚了。至于将炎热化为清肃，将摧残转为平和，更是不用言语形容也明白了。如果在秋季受伤于湿气，这就是秋金之气突然收敛，导致体内含有濡湿的缘故。仍然顺应时令而降，从细微到显著，肺气才能清朗，这是顺应秋气的规律，是保养收敛之道的原则。《别录》说主治“和中”，即调和中央长夏的土气，借助火土交接之际，使得金火不相刑克，从而能够下降而入，入后又上升，上升后又外出，五行均衡，运化循环不息，这也是不用言语形容就能明白的道理。
（由夏转秋，将炎热敲打成清肃，这即是点火成金，不需要另外寻找种子。）
[Recorded in the *Bie Lu* as a Lower Grade herb]
In summer, the pulse is at the skin level like a hook; in winter, the pulse is at the bone level like Ying Qi (Nutritive Qi) circulation.
[Flavor and Nature] Sweet, slightly cold, non-toxic.
[Indications] Primarily harmonizes the Middle Jiao (Spleen and Stomach) and directs rebellious Qi downward.
[Evidence] It is said: Sown in February, vines climb and entangle around fences and walls. Leaves are large as cups, round with pointed tips. Flowers come in purple and white, resembling small moths with wings and tail-like appendages. Pods grow beneath the flowers, with over ten varieties: some long, some round, some resembling dragon or tiger claws, others like pig ears or sickles. Shapes vary greatly, all clustering along branches. After the White Dew solar term, fruits proliferate further; if autumn heat persists, growth becomes difficult. Hence, it is also named "Xue Mei" (Snow Eyebrow) due to shared energetic affinity, and "Liang Yan Dou" (Cool Propagating Bean). Colloquially misnamed "Yang Yan Dou" (Sheep Eye Bean), likely due to shape similarity. When tender, it can serve as vegetables or tea ingredients; when mature, seeds are harvested for boiling and eating. Seeds exist in black, white, red, and mottled colors. For medicinal use, only white seeds are selected. Although pods may be thick, seeds that are coarse and round are superior.
My late father said: Shu (Beans) are among the five grains. Ripening in autumn, they turn white, with sweet fragrance. This embodies the meaning of Earth, Metal, and Water connecting three Zang organs (Spleen, Lung, Kidney). Thus, it is a substance for harmonizing the Middle and directing Qi downward.
It is also said: Moving rightward and descending, it naturally extinguishes summer-heat, eliminates fever, relieves thirst, and stops dysentery.
[Commentary] It is said: "Bian" (Flat/Spread) sounds like "Bian" (All-around/Pervasive), symbolizing the opening of doors. If the pulse is at the skin in summer, hibernating insects prepare to leave, representing the image of broken or open doors. "Bian" also sounds like "Bian" (Pervasive); Jia He (Fine Grain) beans are grains of the Water storage. If the pulse is at the bones in winter, hibernating insects seal their doors, representing the image of a gentleman residing indoors. Referencing *Yong Lei Qian Fang*. To stabilize a fetus on the verge of falling or breaking, the meaning of "broken door" and "opening door" becomes clear without need for verbal description. Transforming炎 (Heat/Fire) into Qing Su (Clear and Dry), turning destruction into peace, requires no verbal description either. If injured by dampness in autumn, this is sudden contraction of Autumn Metal, causing internal dampness retention. One must still follow the seasonal descent, from subtle to manifest, so Lung Qi becomes clear. This is the response to Autumn Qi, the way of nourishing conservation. The *Bie Lu* states it harmonizes the Middle, which means harmonizing the Central Earth of Late Summer. Leveraging the handover between Fire and Earth, Metal and Fire do not punish each other, allowing descent and entry. Entry leads to ascent, ascent leads to outward movement. Five Elements remain balanced, cycles revolve endlessly, which again needs no verbal description.
(Transitioning from Summer to Autumn, transforming Heat into Clear Dryness is akin to igniting fire to create Metal, requiring no separate seed.)
