[Names] Xiejian Dou (Sword-Clasping Bean).
Li Shizhen stated: It is named after the shape of its pod. According to records, Duan Chengshi in *Youyang Zazu* mentioned that there was a "Xiejian Dou" in the Yuelang region; its pods grew horizontally and obliquely, resembling a person clasping a sword under their arm. This refers to this bean.
[Collection and Explanation] Zhao Ying stated: Dao Dou (Knife Bean) is about one chi long and can be used for making sauce.
Li Shizhen stated: Dao Dou is widely cultivated by people. Seeds are sown in March; the vines grow and extend one or two zhang long. The leaves resemble those of Vigna unguiculata subsp. sesquipedalis but are slightly larger and longer. Purple flowers, shaped like moths, bloom in May, June, and July. Pods form, with long ones approaching one chi in length, slightly resembling Glycyrrhiza uralensis (Licorice) pods, flat with a sword-like ridge, clearly showing three distinct edges. When tender, it is excellent when boiled, made into sauce, or candied in honey. When mature, the seeds are harvested; they are as large as a thumb, pale red in color. Boiled with pork or chicken meat, the taste is particularly delicious.
[Flavor and Properties] Sweet, neutral, non-toxic.
[Indications] Warms the middle jiao and directs rebellious qi downward, benefits the intestines and stomach, stops hiccups, tonifies the kidneys and replenishes primordial yuan (Li Shizhen).
[Elucidation] Li Shizhen stated: Dao Dou was not recorded in earlier Materia Medica texts; only recent minor books record its ability to warm and tonify primordial yang. Additionally, there was a case of a patient suffering from incessant hiccups after an illness, audible to neighbors. Someone suggested taking Dao Dou seeds, burning them until carbonized yet retaining their medicinal properties (Cun Xing), and mixing them with plain water for oral administration. Two qian were sufficient to stop the hiccups immediately. This works by directing qi downward and returning it to its origin, thereby stopping the rebellion.

[Correction] Transferred from the Herb Section to this section.
[Names] Lidou (Gu Ben Cao Gang Mu), Hudou (Tiger Bean).
Meng Shen stated: The beans have patterns resembling the head of a civet cat, hence the name.
Li Shizhen stated: "Li" also means black. The pods of this bean turn black when mature, with hairs exposing the veins, resembling the claws of tigers or civet cats. Its seeds also have spots, similar to tiger or civet markings. When boiled, the juice turns black, hence these names.
[Collection and Explanation] Meng Shen stated: Lidou grows in Jiangnan; its vines resemble Pueraria lobata (Kudzu); the seeds resemble Glycyrrhiza uralensis seeds and bear patterns like a civet's head. People stir-fry and eat them, but they have no other medicinal efficacy. Tao Hongjing, in his commentary on the bile of Rhabdophis tigrinus (Tiger Snake), mentioned "resembling Lidou," referring to this plant. *Erya* states: Zhulu is also called Hushè. Another note on the root says: the seedlings resemble legumes. *Erya*: She, which is Hu... Guo Pu commented: In Jiangdong, ... is called Teng (vine), resembling Kudzu but thicker and larger. It twines around forest trees; the pods have hairy spines. Also known as Dousou, which is now Hudou, i.e., Qiansui Teng.
Li Shizhen stated: The "Hu..." in *Erya* is indeed Lidou. The ancients referred to vines as ..., while later generations erroneously changed ... to Li (civet). The "Shan..." and "Hu..." in *Erya* originally referred to two different species. Chen combined them into one, claiming Zhulu is also called Hushè, and further identified it as Qiansui Teng, which is incorrect. Qiansui Teng is listed in the Herb Section. Lidou is wild, though mountain dwellers also cultivate it. Seeds are sown in March, producing vines. The leaves resemble those of Vigna unguiculata subsp. sesquipedalis, but the venation is oblique. Flowers bloom in clusters in June and July, purple in color, resembling Lablab purpureus (Hyacinth Bean) flowers. One branch bears over ten pods, three to four cun long, as thick as a thumb, covered with white down. When mature, they turn black with exposed veins, resembling dried bear claws. The seeds are as large as Dao Dou seeds, pale purple, with spots resembling civet patterns. After boiling to remove the black juice, re-boiling with pork or chicken yields a good flavor.
[Flavor and Properties] Sweet, slightly bitter, warm, slightly toxic. Excessive consumption causes chest stuffiness.
[Indications] Warms the middle jiao, supplements qi (Li Shizhen).
