The *Zhou Hou Bei Ji Fang* (Emergency Prescriptions Kept Up the Sleeve) describes methods for distinguishing changes in form due to spleen and stomach injury: Whenever the spleen pulse presents as slightly flooding (Hong), it indicates injury from bitter/astringent substances; the Classics state that salty flavors overcome bitter. A slightly choppy (Se) pulse indicates injury from pungent/spicy substances; the Classics state that bitter flavors overcome pungent. A slightly slippery (Hua) pulse indicates injury from fishy/salty substances; the Classics state that sweet flavors overcome salty. A flooding and slow (Hong-Huan) pulse indicates injury from sweet/rotten substances; the Classics state that sour flavors overcome sweet. A string-tight (Xian-Jin) pulse indicates injury from sour/hard substances; the Classics state that pungent flavors overcome sour. A slightly string-like (Xian) pulse indicates injury from cold/hard substances; the Classics state that warm properties overcome them. A slightly slow (Chi) pulse indicates injury from cold-phlegm accumulation or foul substances; the Classics state to warm the stomach and resolve phlegm. When food intake is excessive, leading to abdominal distension, fullness, and inability to eat, people usually administer Qi-breaking medicines. (Food injury with aversion to food must present with belching of putrid odor and acid regurgitation.) Before the food is injured, medications are subsequently used to attack, so how can Spleen Qi remain healthy and unobstructed? One must primarily use mild tonifying medicines, assisted by others, promoting one ascending and one descending, allowing communication between Spleen and Kidney, and achieving mutual interaction of Water and Fire, so that digestion and transformation occur naturally.

The method for treating accumulations (Ji Ju) prioritizes regulating Qi. Once Qi ascends and descends properly, and body fluids flow smoothly, how can accumulations arise? Danxi claimed that Qi is formless and cannot form masses or accumulations, focusing solely on resolving phlegm and breaking blood stasis, which is erroneous. Formidable objects in the world often arise from formlessness; why should accumulations be an exception? Dai Fu'an used a single formula, Da Qi Qi Tang (Great Seven Qi Decoction) (to harmonize Qi and Blood, enabling free ascent and descent, circulating body fluids to nourish organs, eliminating stagnation so that accumulations dissolve without direct attack), to treat all types of accumulations. He understood this principle. For Liver Accumulation named Fei Qi (Fatty Qi), decoct the aforementioned soup, let it cool, then pour it over a red-hot iron vessel, and drink while hot. For Lung Accumulation named Xi Ben (Panting Oppression), add Bai Sang Pi (Morus Cortex), Ban Xia (Pinellia Rhizoma), and Xing Ren (Prunus Semen) each 5 fen to the aforementioned soup. For Heart Accumulation named Fu Liang (Hidden Beam), add Shi Chang Pu (Acori Tatarinowii Rhizoma) and Ban Xia each 5 fen. For Spleen Accumulation named Pi Qi (Stagnant Qi), administer Hong Wan Zi (Red Pill) with the aforementioned soup. For Kidney Accumulation named Ben Tun (Rushing Pig), double the Gui Zhi (Cinnamon Twig) in the aforementioned soup, and add Hui Xiang (Foeniculum Fructus) stir-fried with Lian Zi Rou (Meliae Semen) each 5 fen.

Contemporary physicians treating various Qi disorders only seek treatment in the Spleen and Lung, neglecting the Kidney, hence efficacy is rare. The Moving Qi in the Kidney region is the root of the Five Zang and Six Fu organs, the source of the Twelve Meridians, the gate of respiration, and the origin of the San Jiao (Triple Burner). Excessive sexual activity or innate constitutional weakness leads to insufficiency of the Kidney Meridian; Qi loses its control, resulting in frequent stagnation and the generation of various diseases. (All Qi stagnations belong to the Lung. Qi provides warmth; if stagnant and unrelieved, Qi mechanism condenses, and Blood becomes obstructed, giving rise to various diseases. Thus, "all diseases arise from stagnation" is clear evidence.) Physicians believe they should regulate Qi, presenting Hou Po (Magnoliae Officinalis Cortex), Xiang Fu (Cyperi Rhizoma), Wu Yao (Linderae Radix), etc., yet Qi becomes even more difficult to regulate. Using dispersing and purging methods, administering drastic laxatives, results in more than half of patients dying. Subsequently, slightly more skilled physicians attribute the condition to Spleen deficiency failing to transport and transform essence, and thus focus on tonifying the Spleen. However, this merely prolongs life temporarily, often leading to delay and untreatable conditions. This is due to ignorance of the need to tonify the Kidney. One should primarily use Po Gu Zhi (Psoraleae Fructus), Hui Xiang Zi (Foeniculum Fructus), and Hu Lu Ba (Trigonellae Semens). Within Qi-regulating medicines, one must simultaneously use Blood-harmonizing medicines as assistants, for there is no case where Qi is stagnant but Blood is harmonious; if Blood is not harmonious, Qi becomes even more stagnant.
