This is Zuozi Wood (Zaomu, 柞木). It is wood that can serve as a chisel handle; its internal texture is entirely white. The leaves are small with fine serrations, smooth and tough, remaining evergreen through winter. Its wood and leaf forks both possess thorns.
Bark
Taste: bitter, sour, astringent. Qi nature: neutral. The property tends to descend and penetrate, primarily benefiting the orifices. It treats Jaundice (Huangdan, 黄疸) [Burn to ash, take one cun-bi with water, three times daily]. It is used for difficult labor to induce delivery, and treats Shulou (Rat Scrofula/Lymphatic Tuberculosis, 鼠瘘). Jaundice arises from damp-heat stagnating in the intestines and stomach. This herb's bitterness dries dampness, its slight coldness clears heat, and its descending action benefits the orifices, thereby allowing damp-heat to exit via urination. Combined with Yubiao (Fish Bladder, 鱼鳔), Renshen (Ginseng, 人参), Qianlima (Grass Sole/Plantain Seed area grass, 千里马), Baicaoshuang (Soot from kitchen chimney, 百草霜), Niuxi (Achyranthes Root, 牛膝), Baizhi (Angelica Dahurica, 白芷), Danggui (Angelica Sinensis, 当归), and Yimucao (Motherwort, 益母草), it serves as a sacred medicine for inducing delivery. For difficult labor, Zaomu Yin (Oak Decoction) is effective regardless of breech presentation or fetal death in utero. Use one chi of large Zaomu branch, washed clean; five cun of large Gancao (Licorice Root, 甘草), cut into cun segments. Add three sheng and half of freshly drawn water, place in a new clay pot, seal tightly with triple-layered paper, and decoct over mild to strong fire until reduced to one sheng and half. When the patient experiences heavy pain in the waist and abdomen and is ready to give birth, drink one small cup warm. One will feel the lower body opening up, accompanied by thirst. Drink another one to three cups more, and the fetus will be born heavily without other suffering. Do not omit the Gancao.
Leaves
Primary indications: swelling, toxins, carbuncles, and sores. Zaomu Yin treats various types of carbuncles and back abscesses. Use four liang each of dried Zaomu leaves, the center of dried Lotus leaves, dried Daylily roots, Gancao joints, and Diyü (Sanguisorba Root, 地榆). Finely chop. Take half a liang per dose, add two bowls of water, decoct to one bowl. Take once in the morning and once in the evening. For those already suppurated, the pus and blood will gradually dry up; for those not yet suppurated, the toxin will dissipate naturally. Avoid all toxic foods and substances.
Also known as Wei Mao (Euonymus Alatus, 卫矛). In the Qi region, arrow feathers are called "Wei" (Guard). This plant, when dry, has straight feather-like structures resembling a spearhead guarding itself. Burning it dispels evil spirits, hence the name. It grows among mountain rocks, forming clumps from small shrubs. The tender branches have structures like arrow feathers.
Taste: bitter, sour, astringent. Qi nature: cold. Primarily treats women's Bengzhong (Metrorrhagia/Metrostaxis, 崩中) and bleeding, abdominal fullness, and sweating. It expels evil, kills ghost toxins, Gu poison, and Zhu disease (chronic wasting disease, 蛊疰). It treats sudden severe abdominal pain caused by evil qi. It is highly effective for women's blood and qi disorders. It regulates menstruation, breaks masses, stops metrorrhagia and leukorrhea, and kills intestinal parasites. It also treats postpartum blood-stasis abdominal cramps. Ancient formulas treat Zhu disease affecting the heart with unbearable pain using Guijianyu Tang (Arrow-guarding Twig Decoction, 鬼箭羽汤). It is also used in Dahuang Tang (Rhubarb Decoction, 大黄汤) for sudden severe chest pain or acute poisoning by evil qi. (Note by Su Song)
For postpartum blood晕 (fainting due to blood loss) or blood stasis clustering in the chest, shifting to the lower abdomen, or extending to the hypochondrium, use Siwu Tang (Four Substances Decoction, 四物汤) with doubled Danggui, plus Guijianyu, Honghua (Safflower, 红花), removing Huxue (not explicitly named but implied exclusion), each one liang. Grind to powder and decoct for administration.
[Discussion] The Guijianyu recorded in the *Shennong Bencao Jing* seems to specialize in treating the blood aspect of women. The ancient formulas described by Su Song appear to specialize in Zhu diseases and poisons from evil qi affecting the blood. However, medical texts mention Mudanpi San (Moutan Powder, 牡丹皮散) for treating amenorrhea in women, and Jian[X] Wan for treating abdominal distension in men, indicating it is not exclusively for women's blood disorders. Generally, its efficacy is precise and specialized in the blood aspect. Since women prioritize blood, its therapeutic effect on women is more direct and accurate compared to its effect on men.
