【绿豆】
气味寒。味道甘。无毒。主治丹毒、烦热、风疹、因服用金石类药物引发的药毒、热气上冲导致的奔豚病。将生绿豆研磨后绞取汁液服用，也可以煮食。具有消肿、下气、压制热邪、解金石毒的功效。使用时不要去除豆皮，否则会导致人体轻微的气机壅滞。
绿豆性寒，禀受自然界冬季寒冷的水气，进入足少阴肾经。味道甘且无毒，获得大地中正的土味，进入足太阴脾经。
其气味作用降多于升，属性为阴。丹毒、烦热、风疹，都属于心火亢盛。绿豆入肾经，其寒性足以清泻心火，其甘味可以解除热毒，所以能主治这些病症。金石类药物性质大热，多服则导致热毒发作。绿豆之所以能主治，是因为其甘寒之性能解除热毒。奔豚病属于心病范畴。心受到火邪侵袭，将邪气藏于肝；肝受邪后，又将邪气藏于肾。肾气上逆突起，如同小猪奔跑冲撞一般。绿豆之所以能主治，是因为寒性可以清火，甘味可以缓解气逆上冲。热邪过胜则导致肿胀，绿豆性寒能清热，所以能消肿。火性炎上，气热则向上炎蒸，绿豆性寒能清热，所以下气。绿豆性寒所以能压制热邪，味甘所以能解金石之毒。豆皮性寒，所以使用时不可去皮。去皮会导致人体轻微壅滞的原因，是因为失去了皮的寒性制约而偏于甘缓所致。
制方：
绿豆与赤豆、黑豆一起，用醋调敷治疗痘疮痈肿。与大黄、薄荷一起，涂抹治疗丹毒。
扁豆性微温，禀受自然界春季初生的少阳之气，进入足少阳胆经和手少阳三焦经。味道甘且无毒，获得大地中正的土味，进入足太阴脾经。
其气味作用皆主升，属性为阳。所谓“和中”，指的是调和脾胃。扁豆气温入胆经，胆气生发，则脾胃之气宣通，所以说它能调和脾胃。味甘入脾经，脾气健运则气机下行，所以能下气。
制方：
扁豆与人参、白术、白茯苓、甘草、山药、薏苡仁、莲子肉、桔梗、砂仁末配伍，名为参苓白术散。
治疗脾虚湿盛引起的泄泻，以及小儿脾虚证。与麦冬、五味子、黄连、葛根配伍，可解酒毒。
[Green Bean]
The nature is cold. The flavor is sweet. It is non-toxic. It primarily treats erysipelas (Dan Du), vexing heat, wind-rash, drug toxicity triggered by the ingestion of mineral medicines, and Qi rushing upward causing Ben Tun (a condition characterized by a sensation of gas rising from the lower abdomen to the chest). Crush raw green beans, squeeze out the juice, and take it orally; alternatively, it can be boiled and eaten. It reduces swelling, directs Qi downward, suppresses heat, and resolves mineral toxicity. When used, do not remove the skin, as doing so may cause slight Qi stagnation in the body.
Green bean has a cold nature, inheriting the cold water Qi of winter from Heaven, and enters the Foot-Shaoyin Kidney Meridian. Its flavor is sweet and non-toxic, obtaining the central Earth flavor from Earth, and enters the Foot-Taiyin Spleen Meridian.
Its descending action exceeds its ascending action, belonging to Yin. Erysipelas, vexing heat, and wind-rash all belong to Heart Fire. Green bean enters the Kidney meridian; its cold nature is sufficient to clear Heart Fire, and its sweet flavor can resolve heat toxicity. Therefore, it is indicated for these conditions. Mineral drugs have a hot nature; excessive consumption leads to the activation of heat toxicity. Green bean treats this because its sweet-cold property can resolve heat toxicity. Ben Tun is a disease of the Heart. The Heart receives Fire pathogenic factors and stores them in the Liver; the Liver receives them and stores them in the Kidney. Kidney Qi rises abruptly, resembling a pig running and charging. Green bean treats this because coldness can clear fire, and sweetness can relieve the upward rush. Excessive heat causes swelling; green bean’s cold nature clears heat, thus reducing swelling. Fire nature flares upward; when Qi is hot, it flares upward. Green bean’s cold nature clears heat, thus directing Qi downward. Green bean’s cold nature suppresses heat; its sweet flavor resolves mineral toxicity. The skin is cold in nature, therefore it should not be removed during use. Removing the skin causes slight stagnation due to the loss of the skin's cooling constraint, leaving the sweet nature unbalanced.
Prescription:
Green bean combined with red bean and black bean, mixed with vinegar, applied topically to treat acne and carbuncles. Combined with Rhubarb (Da Huang) and Mint (Bo He), applied topically to treat erysipelas.
[Hyacinth Bean / Lablab Bean]
The nature is slightly warm. The flavor is sweet. It is non-toxic. It primarily harmonizes the middle Jiao and directs Qi downward.
Lablab bean has a slightly warm nature, inheriting the early Shaoyang Qi of spring from Heaven, entering the Foot-Shaoyang Gallbladder Meridian and the Hand-Shaoyang Sanjiao Meridian. Its flavor is sweet and non-toxic, obtaining the central Earth flavor from Earth, and enters the Foot-Taiyin Spleen Meridian.
Both its nature and flavor are ascending, belonging to Yang. "Harmonizing the middle" refers to harmonizing the Spleen and Stomach. Lablab bean’s warm nature enters the Gallbladder meridian; when Gallbladder Qi generates and flourishes, the Qi of the Spleen and Stomaxis becomes unobstructed and circulating. Thus, it is said to harmonize the middle. Sweet flavor enters the Spleen meridian; when Spleen Qi is robust, Qi moves downward. Thus, it directs Qi downward.
Prescription:
Lablab bean combined with Ginseng (Ren Shen), Atractylodes Macrocephala (Bai Zhu), Poria (Bai Fu Ling), Licorice (Gan Cao), Chinese Yam (Shan Yao), Coix Seed (Yi Yi Ren), Lotus Seed (Lian Rou), Platycodon (Jie Geng), and Amomum (Sha Ren) powder, named Shen Ling Bai Zhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder).
It treats diarrhea caused by Spleen deficiency with dampness, and pediatric Spleen deficiency syndromes. Combined with Ophiopogon (Mai Dong), Schisandra (Wu Wei Zi), Coptis (Chuan Lian/Huang Lian), and Kudzu Root (Ge Gen), it resolves alcohol toxicity.
