The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "When Shaoyang (Lesser Yang) qi arrives, it manifests as vomiting and regurgitation." It also states: "If wind is injured in spring, sunxi diarrhea (diarrhea with undigested food) arises in summer." The syndrome begins with injury to milk and food, followed by contraction of wind pathogen, thereby damaging the Spleen and Stomach, leading to incessant vomiting and diarrhea. Gradually, coldness spreads to the entire body, limbs, mouth, nose, and nostrils; the hands and feet exhibit slight twitching; the child sleeps deeply with eyes half-open (exposing the sclera). Since infants rely entirely on milk and food for life, excessive vomiting prevents intake, while excessive diarrhea prevents retention. Vomiting injures Qi, and diarrhea injures Blood. Once milk and food are exhausted, and Qi and Blood are further damaged, one must urgently rescue the True Yuan (Original Qi) to avoid exhaustion and collapse.

Liu Junzi Tang (Six Gentlemen Decoction) treats severe damage to the Spleen and Stomach after vomiting and diarrhea in children; or loss of appetite for milk and food after a major illness; and all chronic conditions involving deficiency-cold of the Middle Jiao (Middle Burner).
Ingredients: Ren Shen (Ginseng Radix et Rhizoma, 1 qian), Baizhu (Atractylodis Macrocephalae Rhizoma, stir-fried, 2 qian), Fuling (Poria, 1.5 qian), Banxia (Pinelliae Rhizoma, processed, 0.5 qian), Chenpi (Citri Reticulatae Pericarpium, 0.5 qian), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, 1 qian).
For cold extremities (Jue Leng), add Jiangtan (Zingiberis Rhizoma Preparatum); for severe cases, add Fuzi (Aconiti Lateralis Radix Praeparata, 0.5 qian). For twitching of hands and feet, add Rougui (Cinnamomi Cortex, 0.7 fen), Gouteng (Uncariae Ramulus cum Uncis, 1 qian).
Take as one dose, with Sanjiang (Zingiberis Rhizoma, roasted), three red dates, and a pinch of early rice. Decoct in water and take warm.

(Pediatricians often mistake this for Ji Jing Feng [Acute Convulsion], hence the detailed differentiation.)
Zhang Jingyue stated: "Sudden great fright most easily damages the Qi of the Heart and Gallbladder in children." The *Huangdi Neijing · Kouwen Chapter* states: "Sudden great fright or terror causes separation of Qi and Blood, dispersion of Yin and Yang, severance of meridians, blockage of pulse pathways, reversal of Yin and Yang, emptiness of meridians, disharmony of Qi and Blood, resulting in loss of normal function." This is what the *Neijing* generally describes regarding diseases caused by fright. How much more so for children, whose Qi and Blood differ significantly from adults? If subjected to sudden great fright or terror, the True Shen (Spirit) and Qi will scatter, causing extreme mental confusion. In such a state, where could there be any Excess pathogen? At this time, even rescuing the Correct Qi may prove insufficient; how can one possibly use clearing and dispersing methods again! Herbs like Zhusha (Cinnabaris) and Hupo (Succinum), merely serve the purpose of sedation and anchoring, but they are not methods to treat the root cause. Current pediatric texts erroneously categorize all cases of great fright as Ji Jing Feng (Acute Convulsion), which is a significant error. One should understand that Ji Jing Feng arises from Wind-Heat, while Man Jing Feng (Chronic Convulsion) arises from Spleen-Kidney deficiency; neither necessarily results from fright. (My thousands of words refuting 'Convulsion due to Fright' are fully summarized in Zhang Jingyue's twenty-three characters. If later scholars can comprehend these few sentences, my tedious elaboration here would be unnecessary.) This condition, brought about by great fright, stems fundamentally from injury to the Heart and Gallbladder and the sudden detachment of Spirit and Qi. Treatment should focus primarily on recovering Spirit and Qi. Suitable formulas include Mizhi Anshen Wan (Secret Instruction Calming Spirit Pill), Tuanshen San (Round Ginseng Powder), and Dushen Tang (Single Ginseng Decoction), decocted with Silver and Gold substances.
