Hu Dou (Vicia faba, Broad Bean) has a sweet taste and is non-toxic. It primarily treats Xiao Ke (Wasting-Thirst syndrome, characterized by excessive drinking, eating, urination, and emaciation). Do not boil it with salt to eat. Its seedlings resemble bean plants and grow in wild fields; they are often found mixed with rice grains.

Dong Yi (likely referring to *Setaria italica* or similar grain, contextually distinct from millet but related) has a sweet taste, is neutral in nature, and non-toxic. It benefits Qi, lightens the body, prevents hunger when taken for a long time, strengthens bones and tendons, and enables long-distance walking. It grows in the Hexi region. Its seedlings resemble *Artemisia* (Peng), and its seeds resemble *Malva* (Kui) and can be used as food. The *Book of Wei* records that Dong Yi grows there. It ripens in the ninth and tenth lunar months. The *Guang Zhi* records that Dong Yi's seeds resemble *Malva*, are greenish, and occasionally appear in Liangzhou. The colloquial speech of the Hexi people says: "Lend me Dong Yi, and I will repay you with Tianliang (millet)." ("Yi" is pronounced similarly to "Ji Yang Qie").

Mai Miao (Wheat Seedling) has a pungent taste and is cold in nature, non-toxic. It primarily treats Gu Du (Gu poison). Boil it to extract the juice, filter it through fine silk, and take the decoction. ("Bi" refers to芒秕, chaff/husk, pronounced "Yu Ben Qie").

Cu (Vinegar) has an acidic taste and is non-toxic. It eliminates carbuncles and swelling, disperses water retention, and kills pathogenic toxins (Recorded in *Mingyi Bielu*). [Names] Xi, Ku Jiu (Tao Hongjing stated: Vinegar is derived from wine fermentation, penetrates everywhere, and improves with age; hence called "Xi". Due to its bitter taste, it is commonly called "Ku Jiu" [Bitter Wine]. *Yan Yi* states: Vinegar is made from wine lees; "Qi Lin Zhe" refers to this substance. However, there are types such as Rice Vinegar, Wheat Vinegar, and Date Vinegar, none of which are as mellow as Rice Vinegar. For medicinal use, Rice Vinegar is preferred because it retains the full Qi of the grain, making it superior to vinegar made from lees.) However, modern people find that consuming sour foods softens teeth; this is because Water generates Wood. When Water Qi is weak, Wood Qi becomes excessive, leading to this condition. Vinegar is necessary in tanning leather to create wrinkles, demonstrating its astringent nature, consistent with the theory that "Acidity astringes."
