Buckwheat: The flavor is sweet, the nature is neutral and cold, and it is non-toxic. It solidifies the intestines and stomach (Chang Wei) and boosts Qi strength (Qi Li). Long-term consumption induces wind (Feng), causing dizziness (Tou Xuan). Consuming it with pork may lead to warm wind disease (Re Feng), resulting in the loss of eyebrows and beard. Although it may trigger various ailments, it still mitigates the caustic effects of Dan Shi (mineral drugs), refining the turbid matter of the five zang organs (Wu Zang) and restoring spirit (Jing Shen). It is beneficial for those taking mineral drugs. Its preparation method involves steaming, then sun-drying until the pods open, pounding to remove the husks, and cooking the kernels into rice. The leaves can be eaten as vegetables; they direct Qi downward (Xia Qi) and benefit the ears and eyes, but excessive consumption causes mild diarrhea. Burning the stalks to ash and using the leachate to wash livestock sores, as well as treating restlessness in donkey and horse hooves, is effective. [Supplementary notes from Chen Cangqi, Meng Shen, Xiao Bing, Chen Shiliang, and Ri Hua Zi.]
*Tu Jing Ben Cao* provides detailed descriptions under the entry for Wheat.
Sun Simiao stated: Consuming buckwheat with pork or mutton can cause wind-leprosy (Feng Lai). *Bing Bu Shou Ji* records: For persistent erysipelas (Chi Dan) in children, apply a paste of buckwheat flour mixed with vinegar to cure it.
*Dan Fang Jing Yuan* records: Boiling powder frost (Fen Shuang) with mugwort-ash buckwheat.
Hyacinth Bean (Bian Dou): The flavor is sweet, and the nature is slightly warm. It primarily harmonizes the middle jiao (Zhong He) and directs Qi downward (Xia Qi).
Leaves: Primarily treat continuous vomiting and diarrhea due to Huo Luan (cholera-like syndrome).
Tao Hongjing stated: People plant them along fences; the pods are delicious when steamed, but there is no specific use for harvesting the beans themselves. The leaves are used singly. Those suffering from chills and fever (Han Re Bing) should not consume them. *Tang Ben Cao Zhu* stated: Northerners call it Que Dou (Magpie Bean) because it is black interspersed with white. Ministers Yu Xi et al., according to Meng Shen, noted: Beans treat continuous vomiting and dysentery due to Huo Luan; taken as powder mixed with vinegar, they direct Qi downward. Additionally, for muscle cramps (Zhuan Jin) after vomiting and dysentery, crush one handful of fresh leaves, soak in a small amount of vinegar to extract the juice, and drink it for immediate recovery.
*Yao Xing Lun* stated: White Bian Dou can also be used alone. It detoxifies all herbal poisons; chewing raw or drinking the decoction yields results.
Ri Hua Zi stated: The nature is neutral, and it is non-toxic. It tonifies the five zang organs (Wu Zang). Leaves applied externally treat snake and insect bites.
*Tu Jing Ben Cao* stated: Bian Dou's origin was not recorded in old texts, but it is now ubiquitous. Planted along fences, it climbs upward with large leaves and small flowers. Flowers are purple or white, and pods grow beneath the flowers. The seeds come in black and white varieties; white ones are warm in nature, while black ones are slightly cold. For medicinal use, the white variety should be employed. It primarily resolves toxins from herbs, plants, and alcohol, and also detoxifies pufferfish poison. The flowers primarily treat leukorrhea (Chi Bai Xia) in women; taken as dry powder mixed with rice water.
The leaves primarily treat muscle cramps after vomiting and dysentery; crushed fresh, ground, soaked in vinegar to extract juice, and drunk, it stops symptoms immediately. The black variety is also called Que Dou because the black color is interspersed with white lines resembling magpie feathers.
*Shi Liao Ben Cao* stated: The nature is slightly cold. It primarily treats retching; long-term consumption prevents graying hair. Those with cold qi (Leng Qi) should avoid it. Its leaves treat mass formations (Jia); cooked with vinegar. For muscle cramps, leaf juice mixed with vinegar is effective.
*Yan Yi* stated: Bian Dou has three types: black, white, and magpie, all having white lines on the bean ridge. The white type treats muscle spasms caused by Huo Luan.
