[Wang Kentang] In women, constipation (Dabian Butong) arises from the dysfunction of the five Zang organs, where cold and heat pathogens knot in the intestines and stomach. This leads to the exhaustion of body fluids (Jinye), causing obstruction and stagnation in the large intestine, resulting in constipation. Zhang Zhongjing stated: "If a woman suffers from excessive menstrual bleeding, she loses body fluids, which also leads to difficult defecation." One may select and use San Da Wan San (Three Large Abdomen Powder), Si Wu Tang (Four Substances Decoction) added with Qing Pi (Green Tangerine Peel), or Qi Xuan Wan (Seven Ventilation Pills), Ma Ren Wan (Hemp Seed Pills), according to the specific condition.
[Xue Ji] For the aforementioned conditions, whether due to dryness of the large intestine's body fluids or blood deficiency with fire scorching, one should not rely solely on the duration of the illness. If dietary intake is high, one must wait until abdominal fullness occurs, accompanied by the urge to defecate but inability to do so, before using pig bile (Zhu Dan Zhi) to moisten the intestines. Blindly administering bitter-cold or acrid-dispersing agents will further damage Yuan Qi (Primal Qi), potentially leading to unceasing diarrhea or the formation of Zhong Pi (Middle Jiao Stagnation). Generally, for blood deficiency with fire dryness, use Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder). For combined Qi and Blood deficiency, use Ba Zhen Tang (Eight Treasures Decoction). For blood injury caused by drying agents, use Si Wu Tang (Four Substances Decoction) with Lian Qiao (Forsythia Fruit) and Gan Cao (Licorice Root). For Qi injury caused by purgative attacks, use Si Jun Zi Tang (Four Gentlemen Decoction) with Chuan Xiong (Szechwan Lovage Rhizome) and Dang Gui (Angelica Sinensis). For internal heat causing thirst with a desire for warm drinks and a excess pulse, use Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction) [from Miscellaneous Diseases: Xiao Dan]. For internal heat causing thirst with a desire for cold drinks and a choppy pulse, use Si Wu Tang (Four Substances Decoction) to deliver Run Chang Wan (Moisten Intestines Pills). When Liver and Gallbladder overact on Spleen Earth, impairing transport and transformation, use Xiao Chai Hu Tang (Minor Bupleurum Decoction) [from Shaoyang Syndrome of Cold Damage] added with Shan Zhi (Gardenia Fruit) and Yu Li Ren (Bush Cherry Seed). For Qi deficiency of the intestines and stomach failing to transmit, use Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) added with Shao Yao (Peony Root). For constipation due to accumulation of heat from rich flavors, use Qing Wei San (Clear the Stomach Powder) added with Shao Yao (Peony Root) [from Miscellaneous Diseases: Toothache]. For patterns of Heat Dryness, Wind Dryness, Yang Knotting, and Yin Knotting, one must avoid damaging the Middle Qi; practitioners should examine carefully. A certain woman suffered from phlegm-wheezing with internal heat, constipation, and insomnia for two months. Her pulse was洪大 (Surging and Large), but fine upon heavy pressure. This belonged to deficiency of Liver, Lung, and Kidney. She took Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) in the morning and Xiao Yao San (Free and Easy Wanderer Powder) in the evening, each for over thirty doses. After consuming over a hundred bowls of food, her abdomen began to feel distended and blocked, which corresponds to the previously mentioned "blood deficiency with fire scorching." Pig bile was used to guide the bowels open, and she recovered after regulation with Shi Quan Da Bu Tang (Comprehensive Great Tonifying Decoction).

Chu Yushi said: "I have observed that ancients generally used Qi-descending agents for purgatives. Since Lung Qi does not descend, the Large Intestine cannot transmit waste; examples include Xing Ren (Apricot Seed), Zhi Ke (Bitter Orange Pericarp), and He Zi (Chebulic Myrobalan Fruit). Furthermore, the elderly, deficient individuals, and those with wind disorders lack body fluids, leading to constipation. The Classics state: 'For obstruction, use lubricating methods.' Thus, they used Hu Ma (Sesame), Xing Ren (Apricot Seed), Ma Zi Ren (Hemp Seed), and E Jiao (Donkey-Hide Gelatin). Modern practitioners fail to learn from antiquity, arbitrarily adjusting prescriptions. Whenever constipation occurs, they use harsh purgatives to scour the bowels. This depletes body fluids and Qi/Blood; although the bowels move temporarily, they become more obstructed subsequently, generating other diseases. Once in Lushan, I encountered a self-proclaimed Imperial Physician. A resident official, Wang Shi'an, originally from the capital, initially suffered from wind-induced limb disorders. This physician repeatedly purged him with harsh medicines, later causing Fei Wei (Lung Atrophy) with expectoration of pus and blood, ultimately dying from constipation. Ancients were extremely cautious with medication, unlike modern people who treat life lightly. I cite this to warn future generations."
[Xue Ji] For the aforementioned conditions, if Stomach strength is strong but Spleen weakness prevails, preventing body fluids from distributing everywhere, causing them to only transfer to the Bladder, resulting in frequent urination and difficult defecation, use Pi Yue Wan (Spleen-Restriction Pills). If Yin Blood is exhausted and internal fire blazes, causing Spleen and Lung to lose transmission functions, resulting in constipation and frequent urination, use Run Chang Wan (Moisten Intestines Pills). This pill is effective for patients with severe heat and excess Qi, and for those in the Northwest with robust constitutions. However, if used for people in the Southeast or those with deficiency-heat and insufficient Qi/Blood, it will weaken the Spleen further and dry the intestines, causing false stagnation. This is the treatment method of Mr. Dongyuan. Regarding Sou Feng Shun Qi Wan (Search Wind and Smooth Qi Pills), it is effective for nobles and people in the Northwest, but harmful to those in the Southeast. An elderly woman had the urge to defecate but difficulty passing stool, which was not hard. Her abdomen was sometimes normal, sometimes distended. Her pulses at both Guan and Chi positions were floating and large. I diagnosed this as Qi and Blood deficiency of the intestines and stomach. Each time she took Shi Quan Da Bu Tang (Comprehensive Great Tonifying Decoction) added with Rou Cong Rong (Cistanche Stem), she felt relieved after defecation. If she skipped the medicine for two or three days, her abdomen remained distended and defecation difficult. Another elderly woman had not defecated for over a month, suffering from phlegm-wheezing, internal heat, and inability to lie down. Her pulse was surging and large, but fine upon heavy pressure. She took Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) in the morning and Xiao Yao San (Free and Easy Wanderer Powder) in the evening, each for over fifty doses, consuming over a hundred bowls of food. Her lower abdomen then became stuffy, indicating fire-dryness consuming fluids. Pig bile was used to moisten the intestines, and she stabilized with Shi Quan Da Bu Tang (Comprehensive Great Tonifying Decoction). Later, constipation recurred. She was prescribed Ba Zhen Tang (Eight Treasures Decoction) with doubled Rou Cong Rong (Cistanche Stem) for regular use, which resolved the constipation.
