胎毒初患赤游丹，腹肢先后内外参，内服外贴兼砭血，红轻紫重黑难痊。
【注】小儿赤游丹之证，皆由胎毒所致。欲发之时，先身热，啼叫，惊搐不宁，次生
红晕，由小渐大，其色如丹，游走无定，起于背腹，流散四肢者顺；起于四肢，流入胸
腹者逆。或初生之后，外用热水洗浴，兼以火烘衣物，触动内毒，遂成此证。治之者，先
宜砭出恶血，看血色红者轻，紫者重，黑者死。次宜牛、羊肉片，遍贴红晕处，微干再
易，俟肉片不干，换如意金黄散，用蓝靛清汁调敷。内初服大连翘饮，次服消毒犀角饮。
大便秘结，加生大黄三五分；若烦躁、唇焦、面赤者，宜服五福化毒丹；若失治，毒瓦斯入
里，腹胀坚硬，声音雌哑，吮乳不下咽者，宜服紫雪散下之。一二日间，身轻腹软，热退
身凉，砭处肉活，乳哺如常者生，反此者不治。

The initial manifestation of fetal toxin presents as Chiyou Dan (Red Roaming Erysipelas). The onset involves the abdomen and limbs, requiring a comprehensive assessment of internal and external conditions. Treatment combines internal medication, external application, and bloodletting with a lancet. A lighter red color indicates mild disease, purple indicates severe disease, and black is difficult to cure.
[Note] The condition of Chiyou Dan in infants is caused by fetal toxin. Before eruption, the infant first exhibits fever, crying, convulsions, and restlessness. Subsequently, red halos appear, gradually enlarging from small to large, resembling cinnabar in color, and wandering without fixed location. If the rash originates on the back and abdomen and spreads to the four limbs, it is a favorable prognosis (Shun); if it originates on the four limbs and flows into the chest and abdomen, it is an unfavorable prognosis (Ni). Alternatively, after birth, bathing with hot water externally and drying clothes with fire may stir up internal toxins, leading to this condition. In treatment, one should first use a lancet to prick out evil blood. Observe the blood color: red indicates mildness, purple indicates severity, and black indicates death. Next, apply slices of beef or mutton over the entire red halo area; replace them when they become slightly dry. When the meat slices are no longer dry, switch to Ruyi Jinhuang San (Ruyi Golden Yellow Powder), mixed with clear juice of indigofera tinctoria for topical application. Internally, initially administer Dalianqiao Yin (Large Lonicera Decoction), followed by Xiaodu Xijiao Yin (Detoxifying Rhinoceros Horn Decoction). If constipation occurs, add raw Dahuang (Rhei Radix et Rhizoma) 3-5 fen. If irritability, scorched lips, and flushed face occur, Wufu Huadu Dan (Five Blessings Detoxification Pill) is suitable. If treatment is delayed and toxic qi enters the interior, causing abdominal distension and hardness, hoarseness, and inability to swallow milk, Zixue San (Purple Snow Powder) should be used to purge. Within one or two days, if the body feels light, the abdomen becomes soft, fever subsides and the body cools, the flesh at the pricked sites recovers vitality, and feeding returns to normal, survival is possible; otherwise, it is incurable.
