【黄大豆】
具有宽中、利大肠的功效。
味甘，性温。能宽中下气，利大肠，消除水胀和肿毒。将豆子研成粉末，用熟水调和后涂抹于痘疮愈合后的痈疽处。（凡是痘毒生在要害部位，担心导致遗留疾病，让患者的母亲嚼烂生黄豆，浓敷在患处，即可消退；若痘毒转移到其他部位则另当别论。）豆油，味辛、甘，性热，有微毒。用于涂抹疮疥，解除头发问题（注：此处“解发”疑为古籍传抄错误或特定语境下的用法，通常指治疗脱发或头风等，但依原文直译）。
【白豆】
又名饭豆。具有补调中的功效。
味甘，性平。能补益五脏。（孙思邈说：它是肾脏的谷物，肾病适宜食用。）能温暖肠胃，调理中焦，助益十二经脉。豆腐，参见造酿类。叶子，煮食。能利五脏，下气。
【赤小豆】
具有通利、行水散血的功效。
味甘、酸，性平。颜色赤红。是心脏的谷物。其性下行而通利小肠。（心与小肠互为表里，行水液代谢。同鲤鱼一起煮食，能消除水肿，煮粥食用也很好。）能散血消肿，排脓，清热解毒。治疗泻痢、呕吐、香港脚（注：古病名，类似脚气病）。（过去有患香港脚的人，用赤小豆装袋，早晚踩踏，于是痊愈。）外敷各种疮疽。（用鸡蛋清调和药末箍围患处，药性极粘，干了很难揭开，加入苎麻根末就不粘了。宋仁宗患腮部疾病，道士赞宁取四十九粒赤小豆念咒，混合其他药物敷治而痊愈，宦官任承亮亲眼所见。后来任承亮自己患了恶疮，傅永传授给他一种药，立刻痊愈，询问之下，原来是赤小豆，任承亮这才明白道士念咒是假的。后来他经过豫章，看见医生治疗胁部疽病非常快捷，任承亮问：莫非是用赤小豆吗？医生惊讶地拜谢说：我用此药救活三十多人，希望您不要再次宣扬。凡是溃烂几乎断绝的，将药研末敷上，没有不立即见效的。）能止渴，解酒毒，通乳汁，下胞胎（注：此处“下胞胎”可能指催产或排出死胎，需结合具体语境，此处保留原意）。最能渗泄津液。长期服用使人枯瘦、身体沉重。（《十剂》说：燥可去湿，桑白皮、赤小豆这类药物就是如此。）以颗粒紧小、颜色赤暗的入药。那些稍大且颜色鲜红或淡红的，并不治病。现在药店里半粒红半粒黑的，是相思子。（又名红豆，味苦，性平，有毒。能吐除心腹邪气，治疗风痰、瘴疟、虫蛊毒，研碎七枚服用。）
[Yellow Soybean]
Benefits the middle jiao and promotes bowel movement.
Sweet and warm in nature. Benefits the middle jiao, directs qi downward, promotes bowel movement, reduces water retention and swelling/toxins. Grind into powder, mix with cooked water, and apply topically to sores after smallpox resolution. (If smallpox toxins occur in critical areas, fearing sequelae, have the mother chew raw yellow soybeans thoroughly and apply a thick paste to the affected area, which will resolve them; if they appear elsewhere, treat separately.) Bean oil: pungent, sweet, hot. Slightly toxic. Apply for sores and scabies. Resolves hair issues.
[White Bean]
Also known as Fan Dou (Rice Bean). Tonifies and regulates the middle jiao.
Sweet and neutral in nature. Tonifies the five zang organs. (Sun Simiao said: It is the grain of the Kidney; suitable for consumption in kidney diseases.) Warms the intestines and stomach, regulates the middle jiao, assists the twelve meridians. Tofu: see category on fermentation/brewing. Leaves: boiled and eaten. Benefits the five zang organs, directs qi downward.
[Azuki Bean / Red Bean]
Promotes unblocking, moves water, disperses blood stasis.
Sweet, sour, and neutral in nature. Red in color. It is the grain of the Heart. Its nature descends and unblocks the Small Intestine. (The Heart and Small Intestine are interior-exteriorly related; it moves water. Boiled together with carp, it can reduce edema; making porridge with it is also excellent.) Disperses blood stasis, reduces swelling, expels pus, clears heat, and detoxifies. Treats diarrhea, dysentery, vomiting, and Hongjiaojiao (ancient term for beriberi/foot disease). (In the past, someone suffering from Hongjiaojiao used a bag filled with azuki beans, stepping on them morning and evening, and was cured.) Applied externally to all kinds of sores and carbuncles. (Mixed with egg white powder to bind the area; the nature is extremely sticky, difficult to remove when dry. Adding Pueraria lobata root powder prevents stickiness. Emperor Renzong of Song suffered from facial swelling. Daoist Zannin took forty-nine azuki beans, chanted over them, mixed them with other herbs, applied them, and he was cured. Eunuch Ren Chengliang witnessed this personally. Later, Ren himself suffered from a malignant sore. Fu Yong taught him a medicine, which cured him immediately. Upon inquiry, it was azuki bean. Ren then realized the Daoist's chanting was fake. Later, passing through Yuzhang, he saw a doctor treating a flank abscess very quickly. Ren asked: Is it perhaps azuki bean? The doctor startled and bowed, saying: I have saved more than thirty people with this; please do not reveal it again. For any ulceration nearly fatal, applying the powder works instantly.) Stops thirst, resolves alcohol toxicity, promotes lactation, expels the fetus. Most effective at seeping out fluids. Long-term use causes emaciation and heavy body sensation. (The "Ten Formulas" states: Dryness can remove dampness; examples include Bai Sang Pi [Morus Alba Cortex] and Chi Xiao Dou [Azuki Bean].) Use those that are tight, small, and dark red for medicinal purposes. Those that are slightly larger and bright red or pale red do not treat diseases. What is currently sold in shops as half-red and half-black per seed is Xiangsi Zi (Abrus precatorius). (Also known as Hong Dou [Red Bean], bitter and neutral in nature, toxic. Expels evil qi from the heart and abdomen; treats wind-phlegm, miasma malaria, insect/gu poison. Grind twenty-one seeds and take orally.)
