Zi Yu Pi (Celtis Sinensis Bark): The flavor is sweet, and the nature is neutral. It primarily treats obstruction of urination and defecation. It promotes the flow of water passages. It expels pathogenic factors. Long-term consumption makes the body feel light and reduces hunger. Its fruit (elm seeds) is particularly effective. Also known as Ling Yu. It grows in mountain valleys.
*Dream Interpretations for Fortune*: Dreaming of elm trees and fire symbolizes the descent of the ruler's virtue. Dreaming of lush elm leaves symbolizes the retention of fortune and blessings. *Records of Spring Ming Gate* states: According to *Rites of Zhou*, fire sources change with the four seasons; in the Tang Dynasty, only during Qingming Festival were elm and willow fires bestowed upon close ministers and imperial relatives. *Guanzi* mentions that "five fertile soils" are suitable for planting elms. Fan Shengzhi's *Book of Agriculture* records: In March, there is rain associated with elm pods. *General Principles of Agriculture and Sericulture* records: During past famines in Fengpei, people boiled elm bark into powder for food, relying on it to survive. Li Yuying's poem reads: "Elm coins covering the ground cannot cure poverty." *Qimin Yaoshu* records the method of planting elms: If one can plant one qing of land, they can harvest a thousand bolts of cloth annually (indicating economic value).
Suan Zao Ren (Ziziphus Jujuba Seed): The flavor is sour, and the nature is neutral. It primarily treats cold-heat pathogenic stagnation in the heart and abdomen, qi accumulation, soreness and pain in the four limbs, and damp-bi syndrome. Long-term consumption stabilizes the five zang organs, makes the body light, and prolongs life. It grows in riverbanks and marshes.
Tall jujube branches grow upward (pronounced 'ci'), while low ones spread horizontally. Holding them in the mouth naturally generates saliva when thirsty; consuming them awakens one from drunken stupor. One may beg for a share of vinegar from the vat, using plum to season dishes in the cauldron. Nurturing young saplings requires appropriate material selection; what would a gardener mock?
Li Shizhen stated: Jujube trees have a tall nature, so their branches hang heavily; thorny bushes have a low nature, so their branches grow closely together. Li Gao stated: Sour jujube harmonizes Ying and Wei (nutritive and defensive qi) and generates body fluids. Ma Rong praised: "Containing saliva, spitting forth glory." *Qunfang Pu* records: Consumed raw, it causes insomnia. *Huainanzi* states: Vinegar is sour and does not attract mosquitoes. *Records of the Grand Historian* mentions possessing thousands of jars of vinegar sauce. Bao Zhao's poem says: "Eating plums often brings bitterness." Emperor Xuanzong of Tang's poem says: "Salt and plum have already served as condiments in the cauldron." *Zuo Zhuan* states: "I let its fruits fall, but take its timber." *Mencius* states: "If one only nurtures thorns, one is a mean gardener."
Huang Bo (Phellodendri Cortex): The flavor is bitter, and the nature is cold. It primarily treats internal heat accumulation in the five zang organs and intestines/stomach, jaundice, intestinal hemorrhoids, and diarrhea/dysentery. It stops leukorrhea (red and white discharge) in women and treats erosive ulcers in the genital area. Also known as Tan Huan. It grows in mountain valleys.
The leaves resemble those of Toona sinensis, appearing purple, with a color slightly inferior to Gardenia jasminoides yellow. It grows near golden sands and waters, bearing yin and embracing yang. It unblocks the middle jiao, dyes scrolls, brings supreme auspiciousness, akin to a sovereign ruling by doing nothing. It is listed in the upper grade of *Mu Zhi Pin*. It remains lush in winter, corresponding to musical tones such as Fang and Shang.
Han Baosheng stated: Huang Bo leaves resemble the purple leaves of Toona sinensis. Yuan Zhen's poem reads: "Scattered gardenia calyxes appear yellow." Li Shizhen stated: Zhi Mu combined with Huang Bo embodies the principle of Metal generating Water. Zhang Yuansu stated: The flavor is intense and slightly acrid, representing Yang within Yin. *Book of Jin* states: "All things bear yin and embrace yang." *I Ching* states: "The gentleman has yellow in his center and understands principles." *Chuangjian Ji* records: Paper used for writing was dyed with cypress to repel insects, called "Yellow Scrolls." *I Ching* states: "Yellow lower garment, supreme auspiciousness." Li Zhi's fu says: "Integrating the Great Dao, wearing robes in stillness." Tao Hongjing stated: Daoists include it in the category of Wood Fungi. Zhang Yuxi stated: It does not shed leaves in winter, originating from Fangzhou and Shangzhou.
