1. A young wife in the Jin family, a daughter of an official's household, had a willful nature and frequently suffered from chest and hypochondriac pain accompanied by vomiting, which resolved promptly after treatment. Later, at the end of autumn, these symptoms recurred with more severe vomiting. The illness persisted for two days, progressing to cold extremities, unconsciousness, and a critical state resembling impending death. I was subsequently consulted. Upon arrival, I found several physicians surrounding the patient, all stating that decoctions and other medicines could not be retained; anything taken was vomited immediately, leaving them without recourse. One physician remarked, "Only by using *Dushen Tang* (Single Ginseng Decoction) is there hope for survival." I then examined her pulse and found it chaotic and extremely rapid, accompanied by vexation, heat, and restlessness beyond description. I surmised that unless it was Fire of the Yangming channel, how could it be so acute? I asked if she desired cold water. She nodded immediately. I gave her half a *zhong* (a unit of measure), and this was the only thing she did not vomit; indeed, she seemed to desire more. I then gave her another *zhong*, after which she felt slightly calmer. I then administered *Taiqing Yin* (Supreme Clarity Drink). Others questioned whether this was appropriate since it was not a *Shanghan* (Cold Damage) disease and it was late autumn, asking if her constitution could withstand such cold medicine. I did not argue. After the medicine was swallowed, she slept soundly for half a day, and the vomiting ceased. Subsequently, she recovered after being regulated with light, yin-nourishing formulas. Most vomiting cases belong to Stomach Cold, but here we have a Fire syndrome. As the Classics state: "All upward rushing and counterflow symptoms belong to Fire," which applies exactly to this case. From then on, whenever I encountered vomiting characterized by vigorous and forceful expulsion, a洪数 (Hong-Shu / Surging-Rapid) pulse, and symptoms of vexation and heat, I cured them using this method. This is something one must not fail to know.

2. A three-year-old child in the Hu family accidentally suffered from irregular diet. The pediatrician prescribed medicines primarily for clearing fire and resolving stagnation, which further damaged the Stomach Qi. Consequently, vomiting and loose stools ensued. Additional diuretic and clearing treatments were applied, leading to the expulsion of roundworms (*Ascaris*). Initially, only a few worms were expelled, gradually increasing to dozens, thin as rush grass, sometimes clumping together and emerging continuously day and night. The stool contained similar worms. The child became extremely emaciated and weak, seeking my treatment. I prescribed *Wenwei Yin* (Warm the Stomach Drink) for two or three doses. However, the worms continued to appear morning and evening in large numbers. I initially did not understand their origin or their rapid proliferation. The father pleaded earnestly, "This is our only son; his life depends on you. I implore you to expel these worms first. If the worms are not eliminated, the disease will worsen daily, and he cannot survive." I did not heed his request. Instead, I doubled the amount of Renshen (Ginseng Radix et Rhizoma) in the previous formula and added Fuzi (Aconiti Lateralis Radix Praeparata). After two or three doses, vomiting gradually decreased, and diarrhea stopped. Following the cessation of diarrhea, I alternated between *Liyin Jian* (Nourish Yin Decoction) and *Wenwei Yin* with modifications. Over ten days, the number of worms diminished. After more than a month, appetite returned, muscle mass increased, and health was fully restored. The grateful father asked, "The child's condition was indeed critical. Why did you treat neither the worms nor the vomiting and diarrhea, yet all three conditions resolved? Please instruct me." I replied, "What you fear is the worms; what I fear is the Stomach Qi. Moreover, all vermifuges damage the Stomach Qi. Had the Stomach Qi been further damaged, not only would the worms not have been expelled, but life itself would have been lost. What harm could be greater? Therefore, the key to preserving life lies in understanding the root and the branch. If the Spleen and Stomach are strengthened daily, the source of worm generation is eradicated, and all three diseases are resolved simultaneously. How dare the worms and diarrhea persist?" Those who heard this sighed in admiration and recorded this commentary.

Another case involved a young wife in the Wang family, under twenty years old, who habitually enjoyed melons and raw/cold foods. She frequently suffered from heart and abdominal pain, during which she abstained from food for several days. After turning twenty, each episode was accompanied by vomiting roundworms. Initially, few worms were vomited, but the frequency and quantity increased daily, often expelling ten to twenty worms per episode, accompanied by ten days of fasting. Previous physicians focused solely on attacking the worms; the worms were expelled but regenerated, rendering various medicines ineffective. I examined her pulse and symptoms and investigated the cause, determining that injury from raw/cold foods led to Spleen and Stomach Deficiency-Cold, causing Yin-Dampness to accumulate. Thus, this syndrome arose. Without warming and nourishing the Spleen and Stomach to cut off the source of Cold-Dampness generation, merely attacking the worms would result in their recurrence without benefit. I prepared *Wenzang Wan* (Warm the Viscera Pill) for her. The illness resolved before the medication was finished. Later, due to her youthful indiscretion, she resumed consuming raw fruits, causing a relapse. Taking the pill again led to complete recovery. Observing these two cases: the boy developed worms because cold medicines injured the Spleen; the woman developed worms because raw fruits injured the Stomach. This demonstrates that internal invasion of Yin-Dampness and Spleen-Stomach Deficiency-Cold are the causes of worm generation. Therefore, in treating worm syndromes, provided there are no other signs like Childhood Malnutrition Heat (*Ganre*), the primary approach should always be warming and tonifying the Spleen and Stomach.
