To treat infants and young children suffering from the accumulation of four syndromes: **Jing Feng** (Convulsive Wind), **Re Bing** (Heat Disease), **Feng Tan** (Wind-Phlegm), and **Shi Ji** (Food Retention) in the chest and diaphragm. This causes the child to be drowsy, heavy, with blocked orifices and closed qi mechanisms in all pulses. Consequently, the child remains silent, desires food but cannot eat, wishes to rise but lacks strength, and is fatigued and prone to lying down. Those who do not understand these symptom patterns should administer this prescription if there has been no vomiting or diarrhea; it will immediately restore consciousness. **Da Xiao Shu Feng San** (Great Efficacy Wind-Dispersing Powder) is an excellent formula.

* Jin Wen Da Huang (Rhubarb Root and Rhizome, *Rhei Radix et Rhizoma*) - 3 liang, firm texture
* Ji Xin Bing Lang (Betel Nut, *Arecae Semen*) - 2 liang
* Jiu Chen Ju Pi (Tangerine Peel, *Citri Reticulatae Pericarpium*) - 2 liang, white pith removed
* Po Xiao (Mirabilite, *Natrii Sulfas*) - 1 liang
* Hei Qian Niu (Black Morning Glory Seed, *Pharbitidis Semen*) - 1.5 fen, cooked

Grind the above five herbs into powder. For a two-year-old child, administer half a spoonful; for a three-year-old, one spoonful. First, mix with raw honey, then decoct Mint Water (*Bohe Tang*, *Menthae Haplocalycis Herba*) to wash down the powder. Administer at any time.

Commentary: Wind-phlegm located in the upper jiao causes vomiting; located in the lower jiao causes diarrhea. After one dose, peace and comfort are determined. Do not hastily administer other medicines, as they may interfere and cause errors. Ordinary people merely mix substances like Borneol (*Naozi*), Musk (*Shexiang*), Cyperus (*Xiang Fu*), Ginseng (*Ren Shen*), Poria (*Fu Ling*), Atractylodes (*Bai Zhu*), and Prepared Aconite (*Fu Zi*), which lack purgative properties. How can such a mixture properly regulate these four syndromes?

Commentary: The Five Kan (Chronic Malnutrition Syndromes) and Eight Dysenteries are detailed in classic texts. However, fundamentally, Kan arises from pathologies in the five Zang organs, hence its five names. As it transmits according to shun/ni (favorable/unfavorable) patterns and affects the Zang-Fu, the disease does not strictly follow fixed symptom patterns. One cannot rigidly adhere to the numbers "Five Kan" and "Eight Dysenteries." Kan originates from dietary irregularities leading to Kan-Dysentery; Dysentery originates from Spleen-Stomach weakness accepting accumulated toxins. The principle of treating Kan is to regulate the Spleen and Stomach, warm the middle, tonify Qi, and eliminate Kan-worms. The principle of treating Dysentery is to regulate the intestines and stomach, remove dampness, harmonize the middle, nourish blood, and harmonize Qi.

When infants and young children consume meat too early, damaging the Spleen and Stomach, causing indistinguishable water and grain, retention of stagnation, and failure to transform, resulting in Kan-Qi symptoms, **Da Xiao Shi Jun Bing Lang Wan** (Great Efficacy Quinquina Betel Pill) is appropriate.

* Rou Dou Kou (Nutmeg, *Myristicae Semen*) - 2 pieces, processed
* Bing Lang (Betel Nut, *Arecae Semen*) - 1 piece, raw
* Xuan Lian (Coptis Rhizome, *Coptidis Rhizoma*)
* Hu Huang Lian (Picrorhiza Root, *Picrorhizae Rhizoma*)
* Chen Pi (Tangerine Peel, *Citri Reticulatae Pericarpium*)
* Qing Pi (Green Tangerine Peel, *Citri Reticulatae Pericarpium Viride*)
* Chuan Li Zi Rou (Fructus Toosendan, *Toosendan Fructus*) - stir-fried
* Wu Yi (Alpinia Oxyphylla Fruit, *Alpiniae Oxyphyllae Fructus*) - stir-fried, peel removed
* Shen Qu (Massa Medicata Fermentata, *Medicated Leaven*)
* Mai Ya (Sprouted Hordeum Grain, *Hordei Fructus Germinatus*) - both stir-fried
* Mu Xiang (Aucklandia Root, *Aucklandiae Radix*)
* Ye Ming Sha (Bat Guano, *Vespertilionis Faeces*) - stir-fried, soil removed
* Lu Hui (Aloe, *Aloes*)
* Chuan Xiong (Sichuan Lovage Rhizome, *Ligustici Chuanxiong Rhizoma*) - each 1 liang
* She Xiang (Musk, *Moschus*) - 1 zi

Grind the above into powder. Form pills using Pig Bile (*Zhu Dan*) and Mint juice, sized like hemp seeds. Take 30-50 pills per dose, washed down with warm rice water.

Commentary: Retention is the mother of Kan; thus, untreated retention eventually becomes Kan syndrome. If treatment fails to move the retention, it remains while the Zang become deficient, forming Kan, which is particularly serious. Generally, when children suffer from Kan, does diarrhea always present with wind signs? No. Only Kan-diarrhea is termed Heat Diarrhea because the movement of Zang-Fu is limited, so it does not generate wind. Although there is diarrhea without wind, it may transform into other symptoms: thirst, deficiency heat, dryness and irritability, dysentery, swelling and fullness, panting and urgency—all are Kan deficiency symptoms. Ancient texts state: "Kan deficiency requires tonification," indicating that Kan disease must not be treated with purgatives that disturb the Zang-Fu. At the onset, it is called Kan-Qi; abdominal distension and urgency is called Kan-Xu; frequent diarrhea and dysentery is called Kan-Ji; five-palm heat and vexation is called Kan-Re; brittle hair, prominent abdominal veins, and pica is called Kan-Ji (pathology has reached the extreme); alternating fever and chills, emaciation, dull complexion, and loss of muscle color is called Kan-Lao; small hands and feet, long neck, exposed bones, flat buttocks, abdominal distension, and protruding umbilicus is called Ding Xi; vomiting upon eating, separated cranial sutures, drinking water, and worms emerging from the mouth is called Bu Lu. These are all Kan symptoms.

Furthermore, excessive consumption of cold, raw, sticky, fatty, and greasy foods leads to retention in the Zhong Wan (Middle Jiao) that fails to digest, eventually becoming Kan over time. The method for treating Kan involves assessing severity, regulating the Zang-Fu, harmonizing the Zhong Wan, and smoothing the San Jiao (Triple Burner). This warms the Stomach Qi to increase appetite, strengthens the Spleen via pills to aid digestion, thereby naturally adjusting the Zang-Fu. It ensures Qi and Blood meridians interact, abdominal tendon strength and bone strength are robust, spirit is clear, Kan dissipates, worms dissolve, and recovery occurs gradually. If one uses drugs to attack, the Five Zang become dispersed, the intestines and stomach purge retained toxins, and worms are expelled. Although this appears medical, it is not the correct treatment. Because children's Zang-Fu are deficient: deficiency generates worms, deficiency causes retention, deficiency leads to Kan emaciation, deficiency causes distension. How can purgatives be used further? If the intestines and stomach are further disturbed, deficiency leads to Kan, Kan-deficiency symptoms arise, and innocent children become difficult to save.
