Discussion on Diarrhea Syndromes: Sudden watery diarrhea and water-like diarrhea are common in summer and autumn, mostly caused by dietary injury and consumption of raw or cold foods. The manifestation is sudden, severe, and incessant diarrhea, requiring careful inquiry into the medical history. If accompanied by belching with acid regurgitation, dry heaving, and foul odor, this indicates food stagnation (accumulation of undigested food). One may first administer one or two doses of Yinggan Wan (Miracle Response Pill), followed by Lizhong Wan (Regulate the Middle Pill), Renshen Doukou San (Ginseng and Cardamom Powder), Shouzhong Jin Wan (Guard the Center Gold Pill), Laifu Dan (Restore Life Elixir), or Wenyi Wan (Warm the Stomach Pill) (all above medicines have warm properties); for severe cases, Fuzi Lizhong Wan (Aconite Regulate the Middle Pill), Lizhong Wan, Sizhu San (Four Pillars Powder), Yihan Wan (Eliminate Cold Pill), Wenzhong Liangjiang Wan (Warm Middle Galangal Pill), Erjiang Wan (Two Gingers Pill), Huolun San (Fire Wheel Powder), Chaozhen Dan (Pay Homage to Truth Elixir), Zhengyuan San (Correct Origin Powder), Jinye Dan (Golden Fluid Elixir), Erqi Dan (Two Qi Elixir) (all above medicines have hot properties), or Dingxiang Doukou San (Clove and Cardamom Powder) (slightly hot with astringent and consolidating effects) may be used. Careful examination is essential; if there is no food stagnation, Yinggan Wan should not be given, and antidiarrheal medicines should be used directly. For vomiting and diarrhea accompanied by abdominal pain, Muxiang Tuiqi Wan (Costus Directing Qi Pill), Chenxiang Wan (Agarwood Pill), Dingxiang Wan (Clove Pill), or Yinggan Wan may be administered. For patients with chronic illness, weakness, advanced age, or deficient qi, who suffer from persistent visceral diarrhea, Renshen Doukou San, Nongchang Wan (Thick Intestine Pill), Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder), Buhuanjin Zhengqi San (Unchanging Metal Correct Qi Powder), or Sijunzi Tang (Four Gentlemen Decoction) may be prescribed.
Discussion on Cholera-like Vomiting and Diarrhea Syndromes: Vomiting and diarrhea associated with cholera (Huo Luan) present as either cold or heat syndromes. In cases dominated by cold without thirst, Lizhong Wan, Jiangfu Tang (Ginger and Aconite Decoction), or Laifu Dan may be given. For cholera-like vomiting and diarrhea with heat signs, restlessness, and thirst, Xiangru San (Elsholtzia Powder), Wuling San (Five Ling Powder), Jiahe San (Harvest Abundance Powder), Shenling Baizhu San, or Sijunzi Tang may be taken. After cholera-like vomiting and diarrhea, to regulate the spleen and stomach, Shenling Baizhu San, Jiahe San, Wuling San, Sijunzi Tang, or Tiaoqi San (Regulate Qi Powder) may be used. For thirst, Shenling Baizhu San can be used to alleviate it; prolonged use is particularly beneficial. In cases of cold sweat and softness of the hands and feet, add Jinye Dan, Erqi Dan, or Chaozhen Dan. If ineffective, moxa acupuncture may be applied to Qihai (CV-6). Once vomiting and diarrhea cease, hot-natured medicines should be stopped, and only warm-natured medicines should be used to tonify the spleen.
Discussion on Dysentery Syndromes: These arise from dietary irregularity damaging the spleen and stomach, causing mixing of water and grain, dysfunction of transformation and transportation, retention within the body leading to difficult evacuation, and the interplay of cold and heat pathogens, resulting in dysentery. When cold qi interacts, the stool is white; when heat qi interacts, the stool is red. The treatment principle involves first using warm medicines to harmonize the spleen and stomach, followed by syndrome-specific treatment. Generally, diagnosis requires careful inquiry regarding tenesmus (urgent desire to defecate with heavy sensation in the anus), abdominal pain (or lack thereof), frequent visits to the toilet, passing three to five times up to five to seven times daily with little or no output. It is also noted that constipation combined with tenesmus and unceasing periumbilical abdominal pain indicates dysentery in both young and old, including pregnant women. It is not merely "no stool"; failing to recognize this syndrome leads to misdiagnosis as simple constipation, so careful differentiation is needed. When a patient visits the toilet and passes only a few drops of stool, which may be red, white, or resemble fish brains, these are all signs of dysentery. For dysentery with mixed red and white discharge, or pure pus, or loose stools, if preceded by cramping periumbilical pain that ceases after defecation, this is accumulation dysentery. Muxiang Tuiqi Wan and Yinggan Wan may be given, two to three doses each, followed by treatment based on the color of the discharge. For mixed red and white dysentery, Zhuche Wan (Park the Cart Pill), Huanglian Ejiao Wan (Coptis and Donkey-hide Gelatin Pill), Nongchang Wan, or Weifeng Tang (Stomach Wind Decoction) may be used. For dysentery with more white than red discharge, Nongchang Wan, Zhuche Wan, or Renshen Doukou San may be prescribed. For dysentery with less white than red discharge, Huanglian Ejiao Wan, Wanjin Wan (Ten Thousand Gold Pill), or Jinxie Wan (Gold Dust Pill) may be used. For pure red or fresh blood dysentery, Huanglian Ejiao Wan, Diyue San (Sanguisorba Powder), or Wanjin Yin (Ten Thousand Gold Drink) decocted with Maidongzi (Ophiopogon seeds) may be administered. Pure blood dysentery requires careful inquiry; fresh blood indicates heat. A slight sensation of tenesmus during defecation also indicates heat. Pure white slippery discharge indicates a cold syndrome; Dingxiang Doukou San, Helile Wan (Terminalia Pill), or Zhuche Wan may be given. If dark clots or purple-black blood are passed, indicating extreme deficiency-cold, with slight slipperiness during defecation, Zhuche Wan, Nongchang Wan, and Dingxiang Doukou San should be used. For chronic mixed red and white dysentery that recurs, with intermittent abdominal pain and resistance to various medicines, Muxiang Tuiqi Wan, Bu'er Wan (Not Two Pill), Zhuche Wan, Nongchang Wan, or Yinggan Wan may be prescribed. For frequent day-and-night dysentery with deficiency and slipperiness, Dingxiang Doukou San and Sizhu San may be taken alternately. Another type is spleen-toxin bleeding, presenting similarly to heat-toxin dysentery but without mental restlessness, dry mouth/thirst, or aversion to cold drinks; for this, Baidu San (Resist Toxin Powder) from *Wangshi Boji Fang* may be used, with Huaihua (Sophora flower) and Kufan (Alum) ground into powder and taken with Wu Mei (Mume fruit) decoction. If there is only dysentery without periumbilical cramping pain, there is no accumulation, and Yinggan Wan is unnecessary initially.
Discussion on Intestinal Wind and Hemorrhoid Syndromes: For intestinal wind bleeding, organ toxin bleeding, or constipation with heat, Sanhuang Wan (Three Yellow Pill) or Huanglian Ejiao Wan may be taken, swallowed with thickly decocted Muxiang Tang (Costus Decoction). For heat syndromes, Jisu Wan (Chicken Mint Pill), Changfeng Heisan (Intestinal Wind Black Powder), Jinxie Dan, Wanying Wan (Universal Response Pill), or Siwu Tang (Four Substances Decoction) decocted with Jingjie (Schizonepeta) and Fangfeng (Saposhnikovia) may be used. For various hemorrhoid flare-ups, Diaochang Wan (Hook Intestine Pill) may be administered. For unruptured hemorrhoids, Qudu San (Drive Out Toxin Powder) may be used, along with topical application of pig bile.
