Regular consumption of this formula aids digestion and resolves phlegm; it is indispensable for those who prioritize health preservation.

Zhiqiao (Fructus Aurantii, 1.5 liang, stir-fried), Guigui (Cortex Cinnamomi, 1 liang), Banxia (Rhizoma Pinelliae, washed with decoction), Jiegeng (Radix Platycodonis, each 2 liang).
Grind the above ingredients into a fine powder. Use ginger juice to cook a wheat paste, mix with the powder to form pills the size of *Koelreuteria* seeds. Take twenty pills per dose at any time, administered with ginger soup. Administer one to two doses daily.

This formula was originally used to treat arm pain, as recorded in *Zhimi Fang*. It states that someone suffered from arm pain, unable to lift their limbs, or experienced stagnation in the Zhongwan region, where Spleen Qi failed to circulate smoothly. The Qi clashed upwards. Since the four limbs belong to the Spleen, Spleen stagnation causes Qi to fail to descend and instead ascend, resulting in arm pain. Later practitioners identified this arm pain as a Phlegm syndrome; treating the Phlegm naturally stopped the pain. Furthermore, women suffering from asthma and edema of the four limbs postpartum were cured using this formula.

Banxia (Rhizoma Pinelliae, 2 liang), Fuling (Poria, 1 liang), Zhiqiao (Fructus Aurantii, pith removed, bran-fried, 0.5 liang), Fenghua Puxiao (Fused Mirabilite, 1 fen).
Grind the above ingredients into a fine powder. Use ginger juice to cook a wheat paste, mix with the powder to form pills the size of *Koelreuteria* seeds. Take thirty pills per dose, administered with ginger soup. Fused Mirabilite is difficult to prepare quickly; however, one can sprinkle Puxiao (Natrii Sulfas) on a bamboo tray, add a small amount of water, and place it in a windy area. It will dry rapidly into a substance resembling Mangxiao (Natrii Sulfas crystallized). Scraping and using this is also acceptable.
Repeatedly, individuals troubled by Phlegm reported that during the night, both arms felt as if being pulled, and their hands trembled so severely they could not even hold a teacup. Symptoms resolved immediately upon taking the medicine. Although there are many formulas for treating Phlegm, none produce such miraculous effects as swiftly as this one.

Human Qi and blood vessels should flow continuously throughout the body to protect and nourish it. In a day and night, through inhalation and exhalation, there are 13,500 breaths. Blood circulates 810 zhang throughout the body without ceasing, meeting every fifty cycles, like a circle without beginning or end. Therefore, those practicing Chan meditation sit cross-legged and engage in deep visualization; those learning Daoist immortality practices perform Tu Na (breathing exercises), Yin Dao (guiding and pulling), and massage. Those who understand the Dao are not driven by Qi and blood but rather utilize them. If emotions such as joy, anger, sorrow, and happiness are not regulated properly, or if daily routines and diet deviate from normalcy, Ying and Wei (Defensive and Nutritive Qi) become obstructed, and Qi and blood become turbid and degenerated. This generates various syndromes of Tan (Phlegm), Xian (Saliva), and Yin (Fluid retention). When condensed and stagnant in the chest and diaphragm, it causes dizziness, palpitations, dysuria or epigastric fullness, asthma, cough, and shortness of breath; when stagnant in the joints, it causes muscle spasms, joint pain, limb dragging, and alternating chills and fever. These three originate from the same source but require different treatments. Tan (Phlegm) resides in the Pericardium, floats upward with Qi, lodges in the Lung Meridian, and manifests due to coughing; Xian (Saliva) resides in the Spleen source, overflows upward with Qi, and flows out from the corners of the mouth; only Yin (Fluid retention) arises in the Stomach Fu organ, manifesting as vomiting. These distinctions must be carefully examined.
