The child may suffer from convulsions due to fright, or physiological changes during growth (Bianzheng), or food stagnation, or alternating chills and fever. If they mistakenly take exterior-releasing or purgative medicines, the Spleen and Stomach are damaged, making it difficult for Qi and Blood to be generated. Symptoms include sallow complexion, emaciation, eye twitching, teeth grinding, sparse hair, and weak legs unable to walk. This belongs to Stomach deficiency, not Liver or Kidney pathology. It should be managed with long-term, gradual regulation to restore Stomach Qi.

My commentary: Medicines with extreme properties are not suitable for the Spleen and Stomach. Moreover, children's diseases often arise from irregular diet, improper temperature regulation, which deplete Spleen and Stomach Yuan Qi. When the root is not solid, pathogens can invade. Some cases are caused by the nursing mother's exposure to the Six Evils, emotional disturbances, or improper diet and lifestyle. If one does not understand the origin and progression of the disease, nor distinguish between urgent and chronic conditions, and mistakenly uses harsh and potent medicines, it severely damages the life-generating Qi of the Spleen and Stomach. This leads to various complications and accelerates premature death. Whose fault is this? Mr. Danxi discussed this in detail in *Ci You Lun* (Treatise on Nurturing Children).

If a child frequently develops wind spots on the body and redness/swelling of the toes, this is Wind-Heat in the Spleen Meridian. Use Fangfeng Tongsheng San (Windproof Unblocking Holy Powder) removing Mangxiao (Mirabilite) and Dahuang (Rhubarb), adding Niubangzi (Arctii Fructus) and Jiuchao Huanglian (Coptidis Rhizoma fried with wine), ground into powder for oral administration. Alternatively, decoct Fangfeng (Saposhnikoviae Radix), Baizhi (Angelicae Dahuricae Radix), Bohe (Menthae Haplocalycis Herba), Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Huangqi (Astragali Radix), and Huangbai (Phellodendri Cortex) in water, and bathe while avoiding wind.

My commentary: For the aforementioned symptoms, if caused by Spleen Qi deficiency with Damp-Heat pouring downward, use Renshen (Ginseng Radix et Rhizoma), [missing character], Danggui (Angelicae Sinensis Radix), and Baizhu (Atractylodis Macrocephalae Rhizoma) to tonify Spleen Qi; Shengma (Cimicifugae Rhizoma) and Chaihu (Bupleuri Radix) to raise Yang Qi; Fuling (Poria) and Zexie (Alismatis Rhizoma) to drain Damp-Heat. If caused by food stagnation generating internal heat, use Sijunzi Tang (Four Gentlemen Decoction) to strengthen the Spleen and Stomach; ShanZha (Crataegi Fructus) and Shenqu (Massa Medicata Fermentata) to digest food; Shanzhi (Gardeniae Fructus) and Chuanxiong (Ligustici Chuanxiong Rhizoma) to clear Liver Heat. If caused by Wind pathogen constricting the Couli (pores), or contracting wind after bathing, use Buzhong Yiqi Tang (Decoction for Supplementing the Middle and Augmenting the Qi) to tonify Yuan Qi, adding Chuanxiong (Ligustici Chuanxiong Rhizoma), Baizhi (Angelicae Dahuricae Radix), and Qianghuo (Notopterygii Rhizoma et Radix) to disperse Wind pathogen. Mrie Jiegu stated: Ban (macules) appear on the skin surface and are often painful; Zhen (papules/rash) hide within the skin and are often itchy. Generally, medicines that stabilize the interior serve as the main treatment, while exterior-releasing medicines serve as auxiliaries.

One child presented with itching, fever, fatigue, and poor appetite. This was Spleen and Lung Qi deficiency with external pathogens clashing. Initially treated with Xiaofeng San (Eliminate Wind Powder) for two doses, followed by Buzhong Yiqi Tang (Decoction for Supplementing the Middle and Augmenting the Qi) added with Fuling (Poria) and Shaoyao (Paeoniae Radix), resulting in recovery.

Another child suffered pain from this condition, with fever and thirst. After taking exterior-releasing agents, symptoms worsened. The child appeared fatigued in form and Qi, with a floating and rapid pulse. This indicated pathogens in the meridians, where mistaken dispersal damaged true Qi. Treated with Ren'an Wei San (Ginseng Stomach-Calming Powder) and Buzhong Yiqi Tang (Decoction for Supplementing the Middle and Augmenting the Qi), leading to recovery.

Another child had itching and fever. After using Xijiao Xiaodu San (Rhino Horn Detoxification Powder), vomiting and diarrhea occurred suddenly. This indicated pathogens exiting through both upper and lower pathways. The rash indeed subsided, and the child recovered without further medication.

Another child had redness and swelling of the scrotum. I treated it as fetal toxin, leading to improvement. Later, the child developed fever and phlegm-wheezing. Examination revealed the mother had constrained Fire and Blood Heat. Using medicines to resolve constraint and cool blood, both mother and child took the herbs and recovered. Subsequently, the child experienced vomiting, diarrhea, dark scanty urine, and eye twitching. Palpation of the Yin-Mao Guan pulse showed redness, indicating Wind-Heat. Treated with Chaihu Qinggan San (Bupleurum Liver-Clearing Powder) added with Goutenguncus Uncariae cum Ramulis uncinatis) and Muzeicao (Equiseti Hiemalis Herba), recovering after one dose.

Another child had leg lesions resembling rosy clouds moving unpredictably. First, Sesame Oil was applied to the affected area, and Bianci (pricking therapy) was used to release evil blood, dispersing the toxin. Then, Jiwei Jiedu San (Nine-Ingredient Detoxification Powder) was administered, bringing stability after one dose.

Another child presented with mild external signs but severe internal constipation. This indicated the pathology was in the Zang organs. Treated with Da Lianqiao Yin (Large Forsythia Drink) and topical application of Shengong San (Divine Efficacy Powder), resulting in recovery.
