（菽豆）安胃养肾
豇豆（专门入肾经，兼入胃经）。味道甘甜且咸。性质平和，无毒。考察李时珍的说法，豇豆可以作为蔬菜、水果或谷物食用，用途最为广泛，是豆类中的上品。又说，豇豆开花结荚时，必定成对垂下，具有“习坎”（重险之意，此处指阴阳相济）的含义；豆形微曲，像人的肾脏，所以称其为“肾谷”，这正适合用来解释它的作用。因此，当肾气虚损时，必须依靠它来主治。（使用豇豆加入少许盐食用，效果很好。）而且此物味甘性平，入肾又入胃，所以凡是胃津不足、口渴不止、呕吐逆气、泄泻痢疾、小便频数以及草莽毒中毒等情况，都能通过其甘味进行调理，从而使各种病症平息。（《袖珍方》记载：中鼠莽毒的人，用豇豆煮汁饮用即可解毒。想尝试的人可以先割取鼠莽苗，用其汁液泼洒，根就会腐烂不再生长。）书中记载治疗各种疾病没有禁忌，唯独水肿患者忌食。补肾气时，也不宜多吃。
（造酿）泻胃火，过服则生寒动气
豆腐（专门入脾、胃、大肠经）。由豆子磨烂后，加入石膏或卤水制成。其性质不温，所以书籍都记载其味甘咸，气寒微毒。并且认为寒性能扰动气机，凡是服用豆腐过多，导致肾中寒气发动，并出现疮疥、头风等症状的，需要用莱菔汤或杏仁来解。（《延寿书》记载：有人因喜好食用豆类中毒，医生无法治愈，一位做豆腐的人说，如果莱菔放入汤中，豆腐就做不成，于是用莱菔汤送下药而痊愈。苏颂说：引发肾气、疮疥、头风的病，杏仁可以解除。）只有当胃火冲击，内热郁蒸，症状表现为消渴、胀满，以及休息痢久治不愈时。（可用白豆腐煎食。）赤眼肿痛。（服用祛风清热药，夜间用盐水浸泡的豆腐片贴敷，酸浆豆腐不可用。）杖疮青肿。（用豆腐切片贴敷，频繁更换。或者用烧酒煮过的豆腐贴敷，颜色变红即更换。）烧酒醉死的人。（心口发热者，用热豆腐切片通身贴敷，冷了就频繁更换。）这时才应当使用它来投治。至于说它能调和脾胃，正是火热去除、热邪清除之后安宁和顺的意思，并不是指体内虚无、无热无火时的温补作用。豆皮性质与豆腐相同，能消除斑痘翳障。（因为质地轻，所以能除翳。）豆芽作为蔬菜，须防止引发疥疮和扰动气机。（因为芽有生的含义，主升发。）
(Shudou) Nourish the Stomach and Support the Kidney
Jiangdou (Vigna unguiculata var. sesquipedalis; Cowpea) [specifically enters the Kidney meridian, and additionally enters the Stomach meridian]. Its taste is sweet and salty. Its nature is neutral and non-toxic. According to Li Shizhen, Jiangdou can be used as a vegetable, fruit, or grain, with the widest range of applications, making it a superior grade among beans. It is also stated that when Jiangdou flowers and forms pods, they hang down in pairs, embodying the meaning of "Xi Kan" (repeated danger/yin-yang interplay); the bean shape is slightly curved, resembling the human kidney, hence referred to as the "grain of the Kidney," which aptly explains its therapeutic action. Therefore, for deficiency and damage of Kidney Qi, reliance on this herb is essential. (Consuming Jiangdou with a small amount of salt is very effective.) Furthermore, since its taste is sweet and nature neutral, entering both the Kidney and Stomach, it can regulate conditions such as insufficient Stomach fluids, persistent thirst, vomiting and regurgitation, diarrhea and dysentery, frequent urination, and poisoning from wild herbs, thereby calming all these symptoms through its sweet property. (The *Xiu Zhen Fang* records: For those poisoned by *Ranunculus ternatus* (Shu Mang), drinking decoction made from Jiangdou resolves the toxicity. To test this, one may first cut the shoots of *R. ternatus*, sprinkle them with Jiangdou juice, causing the roots to rot and preventing regrowth.) The texts record no contraindications for various diseases, except for edema, which should avoid it. When tonifying Kidney Qi, excessive consumption is not advisable.
(Zao Niang) Clear Excess Stomach Fire; Overconsumption Generates Cold and Disturbs Qi
Tofu (Doufu) [specifically enters the Spleen, Stomach, and Large Intestine meridians]. It is made by grinding beans into a paste and adding gypsum or brine. Its nature is not warm; thus, texts record its taste as sweet and salty, and its qi as cold with slight toxicity. It is believed that cold nature can disturb Qi. If Tofu is consumed excessively, leading to the activation of Cold Qi in the Kidneys and resulting in symptoms such as sores, scabies, and wind-headache, it must be resolved using Radish Decoction (Laifu Tang) or Apricot Kernels (Xingren). (The *Yan Shou Shu* records: A person who loved eating beans suffered from poisoning that doctors could not cure. A tofu maker noted that if radishes were added to the broth, the tofu would not set. Consequently, administering medicine with Radish Decoction cured him. Su Song stated: For conditions triggered by Kidney Qi, sores, scabies, and wind-headache, Apricot Kernels can resolve them.) Only when there is an assault by Stomach Fire, internal heat stagnation and steaming, presenting as polydipsia, distension and fullness, and chronic intermittent dysentery, [is it indicated]. (White Tofu can be boiled and eaten.) For red eyes with swelling and pain, take wind-heat resolving formulas; at night, apply slices of Tofu soaked in salt water (sour浆 Tofu should not be used). For contusions and bruising from beating, apply sliced Tofu frequently changing it; alternatively, apply Tofu boiled in rice wine, changing it when it turns red. For death-like coma from alcohol intoxication: if the heart area is hot, apply hot sliced Tofu over the whole body, changing frequently as it cools. In these cases, Tofu should be used. The statement that it harmonizes the Spleen and Stomach refers to the state of tranquility after fire is extinguished and heat is removed, not to warming tonification for interior deficiency without heat or fire. Bean skin has properties similar to Tofu and can remove macules and pustules opacities (due to its light quality, it can clear opacities). Bean sprouts serve as vegetables, but one must guard against inducing scabies and disturbing Qi (as sprouts have the meaning of growth and ascending).
