Huangqi (Radix Astragali) 5 liang, Shaoyao (Radix Paeoniae Rubra/Alba) 3 liang, Guizhi (Ramulus Cinnamomi) 3 liang.
The above three herbs are mixed with one sheng of Kujiu (Vinegar) and seven sheng of water, decocted until three sheng remain. Take one sheng warm. Heart vexation should occur after ingestion; it will resolve after six to seven days of administration. If heart vexation persists, it is due to the obstruction by Kujiu.

[Formula Analysis]
Heart vexation after taking the medicine occurs because Kujiu stops sweating too abruptly. Since sweat is governed by the Heart, stopping it abruptly prevents its discharge, causing heart vexation. It takes six or seven days to resolve because when the healthy qi recovers, the pathogenic factors retreat naturally.

[Collected Explanations]
Wei Litong said: The ancients called vinegar "Kujiu"; there is no other substance referred to as Kujiu. Fine wine vinegar, which is the she-cu made in households, is the same as Zhenjiang red vinegar. Inferior vinegar, such as Baijiu vinegar, is available everywhere, but she-cu is generally used for medicinal purposes.
You Yi said: What is meant by "obstruction by Kujiu" is that the drug's power desires to move but cannot immediately do so; only after accumulating over time does it move freely. Hence it is said that it resolves after six or seven days of administration.

In the disease of Huanghan (Yellow Sweat), the calves are naturally cold. If fever occurs, this belongs to Lijie (Periarthritis). Sweating after eating, along with spontaneous night sweats while lying down in the evening, indicates Laoqi (Consumptive Qi disorder). If fever occurs after sweating, the skin will eventually become scaly and rough like fish scales (Jiacuo); if fever persists, malignant sores will definitely develop. If the body feels heavy and becomes lighter after sweating, eventually the body will become numb (text missing, inferred as Ma Mu). Numbness implies chest pain. There will be sweating from above the waist but no sweating below the waist, with flaccid pain in the loins and hips, feeling as if something is under the skin. In severe cases, there is inability to eat, body pain and heaviness, irritability, and difficult urination. This is Huanghan (Yellow Sweat), treated primarily with Guizhi Jia Huangqi Tang (Cinnamon Twig Decoction plus Astragalus).

[Commentary]
This passage elaborates on the symptoms of Huanghan. However, the textual coherence is lacking, indicating likely bamboo slip disarray; therefore, it is not explained.

Guizhi (Ramulus Cinnamomi) 2 liang, Shaoyao (Radix Paeoniae Rubra/Alba) 2 liang, Gancao (Radix Glycyrrhizae) 2 liang, Shengjiang (Rhizoma Zingiberis Recens) 3 liang, Dazao (Fructus Jujubae) 12 pieces, Huangqi (Radix Astragali) 2 liang.
The above six herbs are decocted in eight sheng of water until three sheng remain. Take one sheng warm. Shortly after, drink more than one sheng of hot thin porridge to assist the medicinal power. Cover warmly to induce slight sweating. If sweating does not occur, administer again.

The Cun Kou (Radial artery at the wrist) pulse is floating and slow. A floating pulse indicates heat; a slow pulse indicates潛藏 (submergence/retention). The interaction of heat and submergence is named Chen (Sinking). The Zu Yang (Dorsalis pedis artery) pulse is floating and rapid. A floating pulse indicates heat; a rapid pulse indicates restriction/stopping. The interaction of heat and restriction is named Fu (Hidden). The interaction of Sinking and Hidden is named Shui (Water/Edition). Sinking implies deficiency in the collaterals; Hidden implies difficulty in urination. The interaction of deficiency and difficulty causes water to flow into the skin, resulting in edema.

The Cun Kou pulse is wiry and tight. Wiry indicates that Wei Qi (Defensive Qi) does not circulate, leading to aversion to cold. Water fails to follow its normal channels and flows into the intestines.

Question: A patient suffers from water retention, with swelling of the face, eyes, body, and limbs, and difficult urination. Upon palpation, instead of mentioning water disease, the patient complains of chest pain, Qi rushing up to the throat, feeling as if a piece of roasted meat is stuck, accompanied by slight cough and wheezing. If this matches what the Master said, what kind of pulse would it be?
Master said: The Cun Kou pulse is sinking and tight. Sinking indicates water; tight indicates cold. The interaction of sinking and tight binds at the Guan Yuan point. Initially, it was mild, unnoticed in youth. After the decline of Yang, Ying and Wei interfere with each other. Yang is damaged and Yin becomes excessive. The bound cold moves slightly, and Kidney Qi rushes upward, causing throat blockage and pain below the chin. Physicians mistook it for Liu Yin (flowing phlegm-fluids) and used harsh purgatives. The rebellious Qi did not cease, and the disease remained. Later, emetics were used again, causing stomach deficiency and vexation, dry throat with desire for water, difficult urination, indigestion, and swelling of the face, eyes, hands, and feet. Then Tingli Wan (Descurainiae Semen/Papaveris Fructus Pill) was given to drain water. The condition improved slightly at first, but after overeating, the swelling returned. There was bitter pain in the chest/diaphragm, resembling Ben Tun (Running Piglet). The overflowing water caused floating, cough, wheezing, and counterflow Qi. One should first attack the rebellious Qi to stop it, then treat the cough. Once the cough stops, the wheezing will improve naturally. Treat the new disease first; the old disease will follow later.
