时珍曰∶ ，本作扁，荚形扁也。沿篱，蔓延也。蛾眉，象豆脊白路之形也。

颂曰∶蔓延而上，大叶细花，花有紫、白二色，荚生花下。其实有黑、白二种，白者温
而黑者小冷，入药用白者。黑者名鹊豆，盖以其黑间有白道，如鹊羽也。
时珍曰∶扁豆，二月下种，蔓生延缠。叶大如杯，团而有尖。其花状如小蛾，有翅尾形
。其荚凡十余样，或长或团，或如龙爪、虎爪，或如猪耳、刀镰，种种不同，皆累累成枝。
白露后实更繁衍，嫩时可充蔬食茶料，老则收子煮食。子有黑、白、赤、斑四色。一种荚硬
不堪食。惟豆子粗圆而色白者可入药，本草不分别，亦缺文也。

（读音为“扁”，收录于《名医别录》中品）
【释名】沿篱豆（俗称）、蛾眉豆。
李时珍说：本作“扁”字，是因为豆荚形状扁平。沿篱，指其藤蔓蔓延生长。蛾眉，形容豆脊上白色纹路像蛾眉的形状。
【集解】陶弘景说：扁豆是人家种植在篱笆墙垣边的，它的豆荚蒸熟后食用味道很美。
苏颂说：藤蔓向上蔓延，叶子大花朵细，花有紫色和白色两种颜色，豆荚生长在花下。果实有黑色和白色两种，白色的性温，黑色的性微寒，入药使用白色的。黑色的称为鹊豆，大概是因为它黑色中夹杂着白色条纹，像喜鹊的羽毛一样。
李时珍说：扁豆在二月播种，蔓生缠绕。叶子大如杯口，圆形而有尖端。它的花状如小蛾，有翅膀和尾巴的形状。豆荚有十余种样式，有的长有的圆，有的像龙爪、虎爪，有的像猪耳、刀镰，各不相同，都成串地长在枝条上。白露节气后果实更加繁茂，嫩的时候可以作为蔬菜或茶料食用，老了就收种子煮食。种子有黑、白、赤、斑四种颜色。有一种豆荚坚硬不堪食用。只有豆子粗圆且颜色白的可以入药，本草书籍没有区分，这也是文献的缺失之处。
【修治】李时珍说：凡是用药，选取硬壳扁豆的种子，连皮炒熟，用于入药。也有用水浸泡去皮以及生用的，根据具体方剂的要求而定。
【气味】甘味，微温，无毒。
孟诜说：性微寒，患有冷症的人不要食用。
陶弘景说：患有寒热往来病症的人不可食用。
【主治】调和脾胃，降气（出自《名医别录》）。补益五脏，主治呕吐逆气。长期服用头发不会变白（孟诜）。治疗霍乱导致的吐泻不止，研磨成粉末用醋调服（同上）。行散风气，治疗女子带下病，解除酒毒、河豚鱼毒（苏颂）。解除一切草木毒素，生嚼或煮汁饮用，可获疗效（甄权）。止住泄痢，消暑，温暖脾胃，祛除湿热，止住消渴症（李时珍）。
【发明】李时珍说：硬壳白扁豆，其子充实，色白微黄，气味腥香，性质温平，得中和之气，是脾之谷。进入太阴经气分，通利三焦，能化清降浊，所以专门治疗中焦脾胃的疾病，具有消暑除湿解毒的功效。软壳及黑鹊色的扁豆，性质微凉，仅供食用，也能调理脾胃。

藤
(Pronounced "Bian", recorded in the Middle Category of *Bie Lu*)
**[Names]** Yanli Dou (common name), Emmei Dou.
Li Shizhen said: It was originally written as "Bian" because the pod shape is flat. "Yanli" refers to its creeping growth habit. "Emmei" describes the shape of the white ridge on the bean, resembling a moth's eyebrow.
**[Collection and Explanation]** Tao Hongjing said: People plant Bian Dou along fences and walls; its pods are very delicious when steamed.
Su Song said: The vines creep upwards, with large leaves and small flowers. The flowers are either purple or white, and the pods grow beneath the flowers. There are two kinds of fruits: black and white. The white ones are warm in nature, while the black ones are slightly cold. The white variety is used for medicinal purposes. The black one is called Que Dou (Magpie Bean), likely because it has white streaks amidst the black color, resembling magpie feathers.
Li Shizhen said: Bian Dou is sown in February and grows as a climbing vine. The leaves are as large as a cup, round with pointed tips. The flowers resemble small moths, with wing-like tails. There are over ten varieties of pods, varying in length and shape—some like dragon claws, tiger claws, pig ears, or sickles—all growing in clusters along the branches. After the White Dew solar term, the fruits become more abundant. When tender, they can be eaten as vegetables or tea ingredients; when mature, the seeds are harvested and boiled. The seeds come in four colors: black, white, red, and spotted. One variety has hard pods that are inedible. Only the coarse, round, white beans are suitable for medicinal use. The Materia Medica does not distinguish between them, which is an omission in the text.
**White Flat Bean (Bai Bian Dou)**
**[Processing]** Li Shizhen said: For medicinal use, select the seeds from hard-shelled flat beans, stir-fry them with the skin until cooked, and then use them. Some methods involve soaking in water to remove the skin or using them raw, depending on the specific prescription.
**[Flavor and Properties]** Sweet, slightly warm, non-toxic.
Meng Shen said: Slightly cold; those with cold syndromes should avoid eating it.
Tao Hongjing said: Those suffering from alternating chills and fever should not eat it.
**[Indications]** Harmonizes the middle jiao, directs qi downward (*Bie Lu*). Tonifies the five zang organs, treats vomiting and reflux. Long-term consumption prevents graying of the hair (Meng Shen). Treats persistent vomiting and diarrhea caused by Huoluan (cholera-like syndrome); grind into powder and take with vinegar (ibid.). Disperses wind-qi, treats leukorrhea in women, resolves alcohol toxicity and pufferfish poisoning (Su Song). Resolves all vegetable and herb toxins; chew raw or drink the decoction for efficacy (Zhen Quan). Stops dysentery, clears summerheat, warms the spleen and stomach, removes dampness-heat, and stops polydipsia (Li Shizhen).
**[Elucidation]** Li Shizhen said: The hard-shelled white flat bean has plump seeds, white with a slight yellow tint, smelling fishy and fragrant. Its nature is warm and neutral, attaining the balance of the middle, making it the grain of the spleen. It enters the Taiyin qi level, unblocks and benefits the Sanjiao, transforms clear yang and descends turbid yin. Therefore, it specifically treats diseases of the Middle Jiao, resolving summerheat, removing dampness, and detoxifying. The soft-shelled and black-magpie-colored beans have a slightly cool nature and are primarily for food, though they also regulate the spleen and stomach.
**[Prescriptions]** Nine new prescriptions.
Huoluan with vomiting and diarrhea: Bian Dou and Xiang Ru (Moslae Herba) each 1 sheng, water 6 sheng, boil to obtain 2 sheng, divide and take (from *Qian Jin Fang*).
Huoluan with muscle cramps: Grind Bai Bian Dou into powder, mix with vinegar and take (from *Pu Ji Fang*).
Polydipsia drinking water: Jin Dou Wan (Golden Bean Pill): Soak Bai Bian Dou, remove skin, grind into powder, mix with juice of Tian Hua Fen (Trichosanthis Radix) and honey to make pills the size of wu zi (wu berry), coat with gold foil. Take ... [text incomplete].
Red and white leukorrhea: Stir-fry Bai Bian Dou, grind into powder, take 2 qian with rice water.
Poisonous abortion: For women suffering abdominal pain after taking herbs to induce abortion. Use raw Bai Bian Dou, remove skin, grind into powder, take 1 cun bi (square inch spoonful) with rice water, or drink concentrated decoction, or form into pills. If fetal qi is damaged but not yet aborted, or if there is jaw stiffness, limb rigidity, spontaneous sweating, head drooping, resembling stroke, with only one chance in nine of survival. Physicians often fail to recognize this, mistaking it for ... [text incomplete].
Arsenic poisoning: Grind raw Bai Bian Dou, squeeze out juice with water and drink (both from *Yong Lei Fang*).
Toxicity from meat of six domestic animals: Burn Bai Bian Dou until carbonized but retaining properties (cun xing), grind into powder, take with cold water; effective (from *Shi Lin Guang Ji*).
Toxicity from bird meat: Take raw Bian Dou powder with cold water (ibid.).
Malignant sores with scabs, itching, and pain: Mash Bian Dou and apply externally; heals when scabs fall off (from *Zhou Hou Bei Ji Fang*).
**Flower**
**[Indications]** Treats red and white leukorrhea in women; take dry powder with rice water (Su Song). Roast, grind, and take to treat metrorrhagia and leukorrhea. Eat as wontons to treat dysentery. Mash with water and drink to resolve fatal drug poisoning. Efficacy is similar to the bean itself (Li Shizhen).
**[Prescriptions]** Two new prescriptions.
Unstopping metrorrhagia: Roast Bai Bian Dou flower until dry, grind into powder. Take 2 qian each time, empty stomach, brew fried rice in water, add a little salt, mix and take; effective immediately (from *Qi Xiao Liang Fang*).
All types of dysentery: Select freshly bloomed Bai Bian Dou flowers, clean without washing, blanch in boiling water. Mix with one strip of pork loin, one green onion, seven peppercorns, and soy sauce. Use the water from blanching the flowers to make dough, wrap into small wontons, grill and cook thoroughly (from *Bi Yong Shi Zhi Fang*).
**Leaf**
**[Indications]** Persistent vomiting and diarrhea due to Huoluan (*Bie Lu*). For cramps after vomiting and diarrhea, crush a handful raw, add a little vinegar, squeeze out juice and drink; immediate relief. Roast with vinegar, grind, and take to treat malaria (Meng Shen). Mash and apply externally for snake bites (Da Ming).
**Vine**
**[Indications]** Huoluan, decocted in equal parts with Lu Gen (Reed Rhizome), Ren Shen (Ginseng Root), and Cang Mi (aged rice) (Li Shizhen).
