泻、利水解毒。
甘涩平。散血消肿。清热解毒。治消渴吐逆。泄痢便数。解鼠莽毒。（按周宪王袖珍方
云∶
中鼠莽毒者、豇豆煮汁饮则解、欲试者、先刈鼠莽苗、以汁灌之、根即烂不生、可见为消伐
之物、又豇豆同米煮作饭、米粒便软小、尤可见其性之克削也、时珍述卢廉夫之言、谓其补
肾、以其豆子微曲如肾形也、不知如肾形者、不过入肾而已、如连翘似心而入心、荔枝核似
睾丸而入肾之类、非能补心补肾也。）
补脾、除湿消暑。
甘平。腥香微黄。（脾之谷也。）调脾和胃。降浊升清。消暑除湿。（能消脾胃之暑。）止
渴止
泻。专治中宫之病。（土强湿去、正气自旺、所以能疗呕吐霍乱、及带下诸证。赤白带下
、炒研末、米饮服二钱、霍乱转筋、研末、醋汤和服、俱妙。）中和轻缓。故无禁忌。然多
食能壅气。伤寒邪炽者勿服。生用或炒研。
涩、祛风。
甘苦涩温。治贼风风痹。味劣。无甚功用。止可作马料。故俗呼马料豆。
下气归元。
甘温。温中下气。利肠胃。益肾归元。止呃逆。（时珍曰∶刀豆本草失载、惟近时小书
载其
暖而补元阳也、有人病后、呃逆不止、声闻邻家、或令取刀豆子烧存性、白汤调服二钱、即
止、此亦取其下气归元、而逆自止也。）
（豇豆）具有止泻、利水解毒的功效。
味甘、涩，性平。能散血消肿，清热解毒。治疗消渴症及呕吐逆气，泄泻痢疾及小便频数，解除鼠莽草的毒性。（按：周宪王《袖珍方》记载：中鼠莽草毒的人，饮用煮熟的豇豆汁即可解毒。想验证这一点的人，可以先割取鼠莽草苗，用豇豆汁浇灌它，其根就会腐烂不再生长，由此可见豇豆具有消伐的作用。另外，将豇豆与米同煮作饭，米粒会变得软小，更可见其药性具有克削之力。李时珍转述卢廉夫的话，认为豇豆能补肾，是因为它的豆子微曲，形状像肾脏。却不知道像肾形的东西，不过是入肾经罢了，就像连翘形状像心而人心经、荔枝核形状像睾丸而入肾经一样，并不是真的能补心或补肾。）
（豇豆）能补脾，除湿消暑。
味甘，性平，气味腥香，颜色微黄。（它是脾谷。）能调和脾胃，降浊升清，消暑除湿。（能消除脾胃中的暑邪。）止渴止泻。专门治疗中焦脾胃的疾病。（脾气强健则湿气去除，正气自然旺盛，所以能治疗呕吐霍乱，以及带下等各种证候。赤白带下，炒熟研成末，用米汤送服二钱；霍乱转筋，研成末，用醋汤调和服用，都非常妙。）药性中和轻缓，因此没有禁忌。但是多吃会壅滞气机。伤寒邪气炽盛者不要服用。生用或者炒熟后研末使用。
（刀豆）具有收敛固涩、祛风功效。
味甘、苦，性涩，温。治疗贼风及风痹。味道劣。没有什么显著功效。只可用作马料。所以俗称“马料豆”。
（刀豆）能下气归元。
味甘，性温。能温中下气，通利肠胃，益肾归元。止呃逆。（李时珍说：刀豆在《本草》中原本没有记载，只有近时的杂书记载它温暖且能补元阳。有人病后呃逆不止，声音传到邻居家，让人取刀豆子烧至存性，用白开水调服二钱，立即停止。这也是取其下气归元的作用，气顺则呃逆自止。）
(Adzuki bean) has the effects of stopping diarrhea, promoting diuresis, and detoxification.
Sweet and astringent, neutral in nature. It dissipates blood stasis, reduces swelling, clears heat, and detoxifies. It treats polydipsia (Xiao Ke), vomiting, and regurgitation; dysentery with diarrhea and frequent urination; and resolves the toxicity of *Rumex japonicus* (Shu Mang). (Note: Zhou Xianwang's *Xiuzhen Fang* records that those poisoned by *Rumex japonicus* can be cured by drinking decoction made from boiled adzuki beans. To test this, one may first cut the seedlings of *Rumex japonicus*, pour the bean juice on them, and the roots will rot and fail to grow, demonstrating its dissolving and reducing properties. Furthermore, when cooked with rice, the rice grains become soft and small, further revealing its nature of overcoming and reducing. Li Shizhen relayed Lu Lianfu's view that adzuki beans tonify the Kidney because their shape is slightly curved like a kidney. However, objects resembling a kidney merely enter the Kidney meridian, just as Forsythia resembles the heart and enters the Heart meridian, or Lychee seeds resemble testes and enter the Kidney meridian; they do not actually tonify the Heart or Kidney.)
It tonifies the Spleen, removes dampness, and dispels summerheat.
Sweet, neutral in nature, fishy and fragrant in odor, slightly yellow in color. (It is the grain corresponding to the Spleen.) It harmonizes the Spleen and Stomach, descends turbidity, and ascends clarity. It dispels summerheat and removes dampness. (It can eliminate summerheat in the Spleen and Stomach.) It stops thirst and diarrhea. It specifically treats diseases of the Middle Jiao (Spleen/Stomach). (When Spleen Qi is strong, dampness is eliminated, and righteous Qi naturally flourishes; thus, it can treat vomiting, cholera-like disorders, and various leukorrhea syndromes. For red and white leukorrhea, roast and powder the beans, take 2 qian with rice water; for cholera with muscle cramps, powder the beans, mix with vinegar water, and take orally; both are excellent.) Its nature is balanced and mild, so there are no contraindications. However, excessive consumption can obstruct Qi flow. It should not be taken when pathogenic factors of Cold Damage are vigorous. Use raw or roasted and powdered.
(Astringent, dispels wind.)
Sweet, bitter, astringent, warm in nature. Treats rogue wind and wind-bi syndrome. The taste is inferior. It has little efficacy. It can only be used as horse feed. Hence, it is commonly called "Horse Feed Bean."
(Descends Qi and returns to the origin.)
Sweet, warm in nature. Warms the middle and descends rebellious Qi, benefits the intestines and stomach, tonifies the Kidney, and returns to the origin. Stops hiccups. (Li Shizhen said: *Douzi* was not recorded in the ancient Materia Medica, but only in recent minor texts that it is warm and tonifies Yuan Yang. A patient suffered from incessant hiccups after illness, audible to neighbors. Someone advised burning Douzi seeds until carbonized, mixing with plain water, and taking 2 qian, which stopped immediately. This also utilizes its ability to descend Qi and return to the origin, causing the rebellion to cease.)
