黄柏一味，炒褐色，为末作丸。
大便燥结，睡中口渴者，此方主之。
肾主五液，肾水一亏，则五液皆涸，故上见口渴，下见燥结也。黄柏味苦而浓，质润而
濡，为阴中之阴，故能滋少阴、补肾水。此经所谓燥者濡之，又谓之滋其化源也。他如六味
地黄丸、虎潜丸，皆益肾之药，均可选用。二方见虚损门。
玄明粉（三钱） 当归尾（五钱）
煎汤调服。
血热便秘者，此方主之。
玄明粉咸寒，取其软坚；当归尾辛利，取其破血。此攻下之剂也，宜量人之虚实而用之
燥在广肠，欲其速出，气弱不能传送而出者，宜用蜜煎导法，或猪胆导法。二法皆见伤
寒门。
叙曰∶霍乱有阴阳二证，夫人共知之。若霍乱未显之时，及霍乱始定之际，医者不察，
而以逆剂左之；病者不识，而以腻食啖之，则死道也。今考古方八首以治霍乱，大都喜通而
恶塞尔。
人参 白术（炒） 干姜（炒） 甘草（炙，各二两）
共为末，蜜丸如鸡黄大，每服一丸，沸汤和下。
寒犯太阴，腹痛，吐泻，霍乱，寒多不饮水者，此方主之。
寒犯太阴脾脏，非止外感寒径中太阴，凡吞寒饮冷，皆是寒气塞于中宫。中、下二焦之
阳不得宣发，则乖隔而腹痛，而吐泻，而霍乱也。霍乱与吐泻有别，乃吐泻之久，亡其津液，
手足抽掣而挥霍，眼目旋视而了乱也。寒者温之，故用干姜之辛热；邪之凑也，其气必虚，
故用人参、白术、甘草之温补。
One ingredient: Huangbai (Phellodendri Cortex), stir-fried until brown, ground into powder and made into pills.
For dry and constipated stools accompanied by thirst during sleep, this formula is indicated.
The Kidney governs the five fluids. Once Kidney Water is deficient, all five fluids become depleted; thus, thirst appears above and dryness/constipation below. Huangbai is bitter and dense in flavor, moist and lubricating in texture, belonging to Yin within Yin; therefore, it can nourish Shaoyin and tonify Kidney Water. This corresponds to the *Neijing* principle of "moisten what is dry," also referred to as nourishing the source of transformation. Other formulas such as Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) and Huqian Wan (Tiger-Kneading Pill), which benefit the Kidney, may also be selected. These two formulas are found in the section on Deficiency Damage.
Xuanmingfen (Natrii Sulfas, 3 qian)
Dangguiwei (Angelicae Sinensis Radix, 5 qian)
Decoct in water and take mixed with the solution.
This formula is indicated for constipation caused by Blood Heat.
Xuanmingfen is salty and cold, used for its ability to soften hardness; Dangguiwei is acrid and promoting circulation, used for its ability to invigorate blood and break stasis. This is a purgative formula; dosage should be adjusted according to the patient's deficiency or excess condition.
When dryness affects the large intestine (Guochang), and one desires rapid evacuation but Qi deficiency prevents transportation and expulsion, the Mi Jian Dao Fa (Honey Suppository Method) or Zhu Dan Dao Fa (Pig Gallbladder Suppository Method) should be used. Both methods are described in the section on Cold Damage.
Narration: Huoluan (Cholera-like disorder) presents with two patterns: Yin and Yang, which everyone knows. However, before Huoluan fully manifests, or immediately after it subsides, if physicians fail to examine carefully and administer contrary treatments, or if patients do not understand and consume greasy foods, death may result. Here, eight ancient formulas are examined for treating Huoluan; generally, they favor unblocking and oppose obstruction.
Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma, stir-fried), Ganjiang (Zingiberis Rhizoma, stir-fried), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, each 2 liang)
Grind all into powder, form pills with honey the size of a chicken egg. Take one pill per dose, dissolved in boiling water.
This formula is indicated when Cold invades Taiyin, presenting with abdominal pain, vomiting, diarrhea, Huoluan, predominance of cold symptoms, and lack of desire to drink.
Cold invading the Taiyin Spleen involves not only external Cold directly striking Taiyin, but also internal accumulation from consuming cold drinks and food, causing Cold Qi to block the Middle Jiao. When Yang Qi of the Middle and Lower Jiao cannot disperse and ascend, disharmony occurs, leading to abdominal pain, vomiting, diarrhea, and Huoluan. Huoluan differs from simple vomiting and diarrhea; it arises after prolonged vomiting and diarrhea deplete body fluids, resulting in violent convulsions of limbs and dizziness/confusion of vision. For Cold conditions, warmth is applied; hence, Ganjiang’s acrid-hot nature is used. Where pathogenic factors gather, Qi is necessarily deficient; therefore, Renshen, Baizhu, and Gancao are used for their warming and tonifying properties.
