豆豉味苦，性寒，无毒。主治伤寒病，头痛及寒热往来，瘴气恶毒，烦躁胸闷，虚劳导致的喘息急促，以及双脚疼痛发冷。又能杀灭六畜胎子中的各种毒素。
陶弘景说：豆豉是饮食中常用的物品。春夏季节气候不和时，经过蒸炒后用酒浸泡服用，效果极佳。根据康伯的方法：先用醋和酒调和蒸煮并晒干，再用麻油拌和，再次蒸煮并晒干，总共重复三次，然后加入花椒末、干姜屑混合均匀，用来送服食物，比现在制作的油豉更好。患脚气的人常将豆豉用酒浸泡，用剩下的渣滓敷在脚上，都能痊愈。好的豆豉产自襄阳、钱塘，香气浓郁美好，取其中间部分效果更好。臣禹锡等人谨按《药性论》记载：豆豉得良（此处疑为脱文或特定配伍，原文如此），能杀六畜毒，味苦、甘。主治下血痢疾如针刺般疼痛者，用豆豉一升，用水浸泡至刚刚淹没豆豉，煎煮一、两沸，绞取汁液一次性服用。如果未愈可再服。又有治疗伤寒突发痢疾腹痛者，用豆豉一升，薤白一把切碎，再煮，待汤色变黑去掉豆豉，分为两次服用。如果未愈再服。熬成粉末能止汗，主治消除烦躁。治疗时行热病，能发汗。又治疗阴茎上的疮痛溃烂，用豆豉一分，蚯蚓湿泥二分，加水研磨调和后涂在上面，干了就换，禁止吃热食、酒、菜、蒜。又有寒热风邪引起的胸中疮，新鲜的可以捣碎做成丸剂服用，效果好。陈藏器说：蒲州的豆豉，味咸，无毒。主治解除烦热，热毒，寒热往来，虚劳，调理中焦，发汗，通利关节，去除腥气，治疗伤寒鼻塞。其制作方法与其他豆豉不同，味道猛烈。陕州还有豆豉汁，放置多年不坏，能大除烦热，入药并不像现在的豆豉心，因为那里没有加盐的缘故。孟诜说：豆豉能治疗长期盗汗的患者，用一升豆豉微炒至香，用清酒三升浸泡，满三天后取汁，冷暖任由患者服用，如果未愈，再做三、两剂就能停止。日华子说：治疗中毒药，蛊气，疟疾，骨蒸劳热，都治疗狗咬伤。
《图经本草》在大豆黄卷条目下有详细记载。
《食疗本草》说：陕府的豆豉汁，远胜于普通豆豉。用大豆制成黄蒸，每斗大豆加盐四升，花椒四两，春天晒三天，夏天两天，冬天五天就制成了。半熟时，加生姜五两，既干净又精细，胜过埋在马粪中发酵的。黄蒸可以用好的豆豉心代替。
《圣惠方》：豆豉以充足为限，只要觉得刺痛就嚼碎豆豉敷在上面，一会儿看到豆豉中长毛就好了。没看到，再嚼碎敷上，昼夜不停，直到看到长毛为止。

Douchi (Fermented Soybean) tastes bitter, is cold in nature, and is non-toxic. It primarily treats Shanghan (Cold Damage disease), headache with alternating chills and fever, miasma and toxic pathogens, restlessness and chest oppression, deficiency-type labor with panting and rapid breathing, and coldness and pain in both feet. It can also kill various toxins found in the fetuses of six domestic animals.
Tao Hongjing stated: Douchi is commonly used in food. During spring and summer when the weather is unharmonious, after steaming and frying, it is soaked in wine and taken, which is excellent. According to Kang Bo's method: First, mix with vinegar and wine, steam, and dry; then mix with sesame oil, steam, and dry again. Repeat this process three times. Then, add ground Sichuan pepper and dried ginger powder, mix well, and take with meals. This is superior to the oil douchi made today. People suffering from foot conditions often soak douchi in wine and apply the residue to their feet, resulting in recovery. The best quality comes from Xiangyang and Qiantang, characterized by strong fragrance and richness; taking the center part is even better. Minister Yuxi and others respectfully note according to *Yaoxing Lun* (Treatise on the Nature of Medicinals): Douchi, obtaining "Liang" (likely a textual error or specific context), kills toxins of the six domestic animals. Its taste is bitter and sweet. It primarily treats bloody dysentery feeling like stabbing. Use one sheng of douchi, soak in water just enough to cover it, boil for one or two boils, squeeze out the juice, and take in one dose. If not cured, take again. For sudden dysentery with abdominal pain due to Shanghan, use one sheng of douchi and one handful of cut scallion white parts, boil further until the soup turns black, remove the douchi, and divide into two doses. If not cured, take again. Roasted into powder, it stops sweating and primarily eliminates restlessness. It treats epidemic febrile diseases and induces sweating. It also treats painful, ulcerated sores on the penis: mix one part douchi with two parts wet mud from earthworms, grind with water, apply topically, change when dry, and avoid hot food, wine, vegetables, and garlic. For sores in the chest caused by wind-cold-heat pathogens, fresh ones can be crushed into pills for oral administration, which is effective. Chen Cangqi stated: Douchi from Puzhou tastes salty and is non-toxic. It primarily resolves vexation and heat, heat toxins, alternating chills and fever, deficiency labor, regulates the middle jiao, induces sweating, opens joint passages, removes fishy odors, and treats nasal congestion due to Shanghan. Its preparation method differs from other douchis, and its flavor is intense. Shanzhou also has douchi juice that does not spoil for years, greatly resolving vexation and heat. In medicinal use, it is not like modern douchi hearts because it contains no salt. Meng Shen stated: Douchi can treat patients with chronic night sweats. Take one sheng, lightly stir-fry until fragrant, soak in three sheng of clear wine for three days, take the juice, and let the patient drink it at any temperature. If not cured, prepare three or two more doses to stop the sweating. Ri Huazi stated: It treats poison ingestion, gu qi (poisonous gas/miasma), malaria, bone-steaming consumption, and dog bites.
*Tujing Bencao* (Illustrated Classic of Materia Medica) details this under the entry for Da Dou Huang Juan (Yellowed Soybean Sprouts).
*Shiliao* (Food Therapy) stated: Douchi juice from Shanfu is far superior to ordinary douchi. Make huang zheng (fermented soybean starter) from soybeans, adding four sheng of salt and four liang of Sichuan pepper per dou of beans. Sun-dry for three days in spring, two days in summer, and five days in winter. When half-cooked, add five liang of fresh ginger. It is clean and refined, surpassing fermentation in horse manure. Huang zheng can be replaced with good quality douchi hearts.
*Shenghui Fang* (Holy惠 Formulas): Limit douchi heart usage to sufficiency. If stinging occurs, chew douchi and apply as a poultice. After a short while, if mold appears on the douchi, it heals. If not, chew and apply again, day and night without interruption, until mold appears.
*Buyu*: Take three sheng of douchi and three sheng of water, stir to extract juice and drink. Moxibustion with Ai Ye (Mugwort) should be performed gently to maintain warmth. If there are existing ulcer holes discharging fluid that does not resolve after three or four days, causing chest... Divide into three doses, take twice daily. Mix, take three times daily, incomparable. Also, bleeding from each point like needle holes. Take three [units] of douchi...
*Xin Jing* (Mirror of the Mind): Primarily treats wind toxicity, spasms and stiffness of feet and knees, and pain in bone joints.
[Various Formulas]: Method to ward off epidemic warmth: Roast douchi and Baizhu (Atractylodes Macrocephala Rhizome), chop fourteen pieces, add three sheng of water, decoct to obtain one sheng, and drink. Another formula for children with alternating chills and fever, invaded by evil qi: Gather douchi with yellow clay, bake until cooked, cool, remove, grind douchi into powder. Mix equal parts of douchi and garlic, pound evenly, form pills the size of wu zi seeds. Each dose... Later, when toxic vapors attack hands, feet, and cause general edema, use Douchi Wine Formula: Lightly stir-fry five he of douchi... Yao Hezhong treated pediatric erysipelas (Dan Du), broken into sores with yellow fluid discharge. Scorch douchi until... After febrile disease attacks eyes causing nebulae: Burn fourteen douchi pieces, grind into powder, blow into eye using a tube... To treat miscarriage with complete blood loss, vexation, and fullness: One sheng of douchi, three sheng of water, boil three times... Grind into powder and apply, not exceeding three or four times. Mao Ting Ke Hua: Small toads are toxic. If the owner suffers from urinary retention, lower abdominal distension, and pain leading to death: Take one he of raw douchi, pour into half a bowl of fresh well water, soak until the water becomes thick/concentrated, drink in one dose, and recover.
