Any infant suffering from jaundice (Huang Bing) should not be treated uniformly. The root and branch causes differ, so the syndromes and treatments also vary. Therefore, *Yinghan Baoshu* states: Jaundice is caused by stomach heat. From this perspective, it results from deficiency of spleen and stomach qi, contraction of damp-heat pathogens, stagnation in the couli (interstices of skin and muscle), infiltration into the skin, accumulation to form jaundice, steaming outward, thus presenting this syndrome. Alternatively, it may arise from spleen and stomach weakness combined with internal attack by zhengpi (abdominal masses and malnutrition). However, ganxia (malnutrition with diarrhea) also primarily manifests as yellowish skin, erect hair, distended abdomen with visible veins, emaciation, lack luster externally, and inevitable body yellowing; this originates from gan disease, leading to these signs. If the treatment is for cases contracted via damp-heat, where the body yellow resembles smoke-stained color, use Wu Ling San (Five-Ingredient Poria Pill) crushed and added with Ephedrae Herba (Mahuang, 麻黄), decocted with water and ginger, administered orally; inducing sweating will lead to recovery. Alternatively, using Yinchen Hao Tang (Artemisia Capillaris Decoction) to regulate Wu Ling San is also good. If obtained due to ganpi, the appearance resembles yellow earth; use Xingpi San (Spleen-Awakening Powder) and Huapi Wan (Mass-Dissolving Pill) to awaken the spleen, invigorate the stomach, grind away accumulations, and manage gan. Once stomach qi harmonizes, food intake doubles, refining and transporting essence, nourishing all bones and viscera, irrigating the zang-fu organs, with the five colors appearing in their respective regions, essence manifesting in the face, and the yellow naturally eliminating.

Some infants are born with whole-body yellowing, only the sclera thick like gold, accompanied by high fever, named Taihuang (Fetal Jaundice). This occurs because before birth, the mother suffered extreme heat transmitted to the fetus, hence this syndrome. The nursing mother should take Shengdi Huang Tang (Rehmannia Root Decoction) so that the medicine enters the milk, allowing the infant to drink it, ensuring safety.

Why does bleeding occur in the nine orifices of children? Essentially, humans possess blood and qi. The Heart is the master of blood, the Lung is the master of qi. Qi governs movement, blood governs moistening, nourishing all bones and viscera, irrigating sunmai (fine collaterals), ascending and descending, harmonizing ying and wei, naturally smooth. Once unharmonious, diseases arise. Either invaded externally by six excesses (Liu Yin, pathogenic factors), or disturbed internally by seven emotions (Qi Qing), qi stagnates and fails to move, blood obstructs and fails to moisten. Internal and external depression prevents flow and nourishment, inevitably causing reckless movement (bleeding). He Hanzhong stated that Kong Mai (Hollow Pulse) signifies blood loss, as it belongs to yang in the seven superficial pulses. The Yangming channel governs abundant qi and blood, never occurring without heat. Generally, both qi and blood become hot, toxins stagnate and force inward, losing normal regulation, thus flowing recklessly. Some infants in swaddling clothes suffer this due to non-emotional causes, but rather because the nursing mother holds grudges, fails to relax, consumes bland spicy foods, which flow into the milk collaterals; after the infant drinks, stagnation persists, steaming internally, moving blood. Or living in heavy curtains and warm rooms, heated by fire, lacking exposure to wind and sun, accumulating warmth into heat, eventually surging and leaking, causing vomiting, epistaxis, or bleeding in bowel/bladder movements. When qi exits and evil heat takes advantage, blood cannot follow its normal channels, seeping into various meridians, producing leakage syndromes. Their faces are pale white, pulse deep and faint, blood light purple, breath slow—this is the presentation. Moreover, infants are fragile, prone to deficiency and excess; internal heat attack causes blood to follow qi, either obstructing and reversing upward, or flowing downward recklessly, resulting in hematemesis, epistaxis, hematochezia, or hematuria. However, blood does not move on its own but is driven by qi; wind does not generate itself but arises from heat. By this reasoning, one can infer others. Treatment first clarifies deficiency and excess, examines the disease source, treats according to the meridian. Medication without error preserves the key mechanism. For excess patterns, Xiao Chai Hu Tang (Minor Bupleurum Decoction) added with Rehmanniae Radix (Shengdi Huang), Imperatae Rhizoma (Simao Gen), or Sophorae Flavescentis Radix (Kushen) is good, decocted in water; or crush Wu Ling San, combine with Wu He Tang (Five-Harmony Decoction), add Imperatae Rhizoma and Sophorae Flavescentis Radix, decoct in water, and administer Xiao Du Yin (Detoxification Drink), followed by intermittent use of Jisu Wan (Chicken Mint Pill) and San Huang Wan (Three-Yellows Pill) from *Ju Fang*. For deficiency patterns, Lizhong Tang (Regulate the Middle Decoction) and Renshen Xiong Gui Tang (Ginseng, Ligusticum and Angelica Decoction) are suitable. Occasionally, physicians see abundant bleeding, assume extreme heat, over-administer cold agents, causing blood to become cold, unable to return to its source, flowing recklessly, appearing dark purple and stagnant, or forming small clots; one should administer Ginger and Aconite preparations to warm, ensuring natural flow and preventing reckless movement.
