赤游丹，是由于胎儿在母体内受热毒侵袭，或出生后护理过于保暖，导致热毒向外发散，表现为皮肤红肿，颜色如同涂抹了丹砂，且游走不定，遍布全身，因此称为赤游丹。如果病症发于头面四肢并向内心腹内部蔓延的，属于难治之症。内服治疗应以清热解毒为主。外用治疗宜采用砭法（用石针或金属针浅刺皮肤出血以泄热）。通过砭法去除恶血后，用鲜猪瘦肉切片贴敷患处。对于已经溃烂破损的部位，使用明雄黄、银朱各等份研成细末撒布其上，确有显著疗效。
按语：本卷列举了二十四种证候，虽然遗漏的病证很多，但治疗方法不依赖汤药，因为小儿不喜欢服药，这种方法对小儿最为适宜。各种按摩手法，也是《灵枢》和《素问》中明确记载的内容。市井医生不懂得遵循经典，而以浅薄鄙陋的眼光看待它，不阅读古书，妄加议论，把凤凰看作鸡，把龙看作蛇。医术的败坏，不是一天形成的了。然而我不敢说所采集汇编的各种方法足以完备，等待将来把汤液方药的方法集成一书，以补充本书的缺失，向海内各位专家请教以弥补不足，这便是我编纂述作的一片诚心，无法抑制罢了。（惕厉子）
Chi You Dan (Red Roaming Erysipelas) arises from heat-toxin in the womb or excessive warmth after birth, causing heat-toxin to manifest externally. The skin becomes red and swollen, resembling cinnabar paint, with a migratory nature that spreads over the entire body; hence it is called Chi You Dan. If the eruption occurs on the head, face, limbs, and moves inward toward the heart and abdomen, it is considered incurable. Internal treatment should primarily focus on clearing heat and detoxifying (Qing Re Jie Du). External treatment should utilize Bian Fa (Stone Needle Therapy). Bian Fa removes bad blood (stagnant blood), followed by applying slices of fresh lean pork to the affected area. For broken or ulcerated areas, apply an equal mixture of finely ground Ming Xiong Huang (Realgar) and Yin Zhu (Vermilion) as a powder dusting; this yields remarkable efficacy.
Note: This volume lists twenty-four syndromes. Although many disease manifestations are omitted, the treatments do not rely on decoctions because infants dislike taking medicine, making this approach most suitable for children. Various massage techniques are also clearly documented in the *Ling Shu* (Spiritual Pivot) and *Su Wen* (Basic Questions). City physicians fail to follow the classics, viewing these methods with superficial contempt, without reading ancient texts and instead engaging in baseless speculation. They mistake the phoenix for a chicken and the dragon for a snake. The deterioration of medical skills has not occurred overnight. However, I dare not claim that the collected methods are sufficient to be complete. I await the opportunity to compile a book on herbal decoction methods to supplement the deficiencies of this work, seeking correction from experts throughout the land to address my shortcomings. This sincere intent to compile and transmit knowledge cannot be suppressed. (Ti Li Zi)
