[From Yuan Rong] Tiaowei San Formula / Also a formula for treating typhoid fever in critical condition / [from Ju Fang] Da Yi Han Wan Formula

Treats all kinds of vomiting and regurgitation. Cold limbs due to Shanghan (Exogenous Febrile Disease). Inability to consume porridge or food.
Shihuang (Realgar, *Auripigmentum*), Shuiyin (Quicksilver, *Hydrargyrum*) (each half liang)
First grind Shihuang into an extremely fine powder. Then add Shuiyin and grind them together until the mixture turns black. Take one qian per dose; for severe cases, take two qian. Mix with warm rice water for administration. There are no restrictions on the time of taking the medicine.
Hu notes: In the above formula, Shihuang is used, which is hot in nature and belongs to Fire. It is toxic. It assists the Pericardium superiorly, benefits the Spleen and Stomach centrally, and tonifies the Mingmen (Gate of Vitality) inferiorly. When ground with Shuiyin, it forms black cinnabar-like particles. This is because Shuiyin is also acrid, cold, and toxic. It can be used temporarily to open up the disharmony of cold and heat in the chest and diaphragm, and to address the rebellious upward flow of cold qi causing vomiting and inability to eat, thereby saving patients from various critical conditions. Occasionally, it may yield results. However, if one encounters cold limbs due to Shanghan and instead of using formulas such as Lizhong Tang (Regulate the Middle Decoction) or Sini Tang (Frigid Extremities Decoction), uses this agent which is purely Yang and purely Yin and highly toxic, would this not be adhering rigidly to a formula and harming people's lives? I therefore record and present this formula, specifically elucidating its rationale, to warn future students of medicine.

Chuanwu (Raw, *Radix Aconiti Lateralis Preparata* - note: text says raw, usually processed but here specified as raw for external/special use context or specific preparation method implied by grinding), Nanxing (Raw, *Rhizoma Arisaematis*), Banxia (Raw, *Rhizoma Pinelliae*), Tianma (Raw, removed rhizome, equal parts)
Grind the above ingredients into a fine powder. Take one qian per dose. Administer with Doulin Jiu (Soybean Dripping Wine), slightly warm. Follow with one or two cups. If the jaw is clenched (trismus), force-feed the medicine. As long as the medicine enters the body, there is no case that cannot be saved.
Hu notes: The "Shanghan" mentioned above actually refers to Zhonghan (Cold Damage). The Qi of the Jueyin and Yangming meridians is rebelling upward. Wind-phlegm and cold-fluid retention obstruct the chest and diaphragm, leading to a near-death state. Only this medicine can open these obstructions. Chuanwu dispels wind, assisted by Tianma; Banxia drives out fluid retention, assisted by Nanxing. These pairs of herbs have contrary properties yet work synergistically. This is an emergency rescue formula.

Treats chronic cold accumulation and deep cold. Weakness of the Zang-Fu organs. Pain in the heart and abdomen. Distension and fullness in the chest and hypochondrium. Diarrhea with borborygmus. Spontaneous sweating. Undigested food in stool. Sudden decline of Yang Qi. Predominance of Yin Qi. Cold limbs.
In Shanghan with excess Yin, coma, short pulse, and lethargy of the four limbs, this formula is suitable.
Ganjiang (Six jin, prepared/pao), Gaoliangjiang (Six jin, prepared/pao), Gui (Four jin, Cinnamon Twig/Cortex Cinnamomi), Bibai (Four jin, there should be missing characters below this line)
Take fifty pills per dose, administered with rice water. This medicine is hot and drying. It treats deficiency-cold of the Zang-Fu organs causing slippery diarrhea, as well as diarrhea with borborygmus and undigested food. For cases of heart and abdominal pain, cold stagnation in the Zhongwan region, and loose stools, it is especially suitable.
Hu notes: Ji Earth belongs to the central Yin Earth. If the Earth is cold, all things fail to grow. The medicinal ingredients in the above formula are all acrid and hot, constituting a formula to warm and nourish the Spleen and Stomach.
*Cishi Nanzhi* states: In Yin syndromes, the body is quiet and heavy, speech is silent, breathing is difficult to distribute, vision is unclear, nasal exhalation does not reach out and inhalation does not enter, the breath from mouth and nose feels cold, fluids and food cannot be taken in, and urination and defecation are incontinent. The face feels aversion to cold, as if scraped by a knife. It also states: If the body surface is cool, the disease is known to be in the Yin meridians. This is named Yin Syndrome. It further states: Abdominal pain locations should be differentiated among the Three Yin meridians. Pain in the Zhongwan area belongs to the Taiyin Meridian, treated with Lizhong Tang (Regulate the Middle Decoction), Jianzhong Tang (Establish the Middle Decoction), Huangqi Tang (Astragalus Decoction), etc. Pain around the umbilicus belongs to the Shaoyin Meridian, treated with Sini Tang (Frigid Extremities Decoction), Zhenwu Tang (True Warrior Decoction), Fuzi Tang (Aconite Decoction), etc. Pain in the lower abdomen belongs to the Jueyin Meridian. Severe cases are treated with Zhengyang San (Upright Yang Powder) or Huiyang Dan (Return Yang Pill). Mild cases are treated with Danggui Sini Tang (Angelica Frigid Extremities Decoction). (Lizhong Tang is seen earlier. Jianzhong Tang refers to Zhang Zhongjing's Xiaojianzhong Tang Formula, which is Guizhi Tang with doubled Shaoyao and added Jiaoyi. Huangqi Tang, I believe, is Jianzhong Tang with added Huangqi. *Neitai Fangyi* states it is suitable for treating deficiency pain. Some say Huangqi Tang consists of Huangqi, Renshen, Fuling, Baizhu, Shaoyao, and Gancao. For those with vomiting, add Huoxiang, Shengjiang, and Chenpi. Details on indications are found in *Yinzheng Lüeli*. Other decoctions have been mentioned previously. Zhengyang San and Huiyang Dan are found in Volume 16 Miscellaneous Formulas of *Huo Ren Shu*, now collected and appended here.)
