尝论此候，因风痰停饮，聚积心胸，再感风热、肺为诸藏华盖，居于膈上，水气泛
溢，则肺为之浮，日久凝而为痰，停滞心胸，兼以风热内发，其外证唇红面赤，咳嗽喘促。
致胸骨高如覆掌，名曰龟胸。治法宽肺化痰利膈，以除肺经痰饮。先用五苓散和宽气饮，
入姜汁、葱汤调服，次清肺饮、雄黄散、碧玉丸、如意膏为治。若投前药，愈而复作传
变，目睛直视，痰涎上壅，兼以发搐，则难治矣。龟背者，盖初生婴孩，未满半周，强
令坐早，客风吹着背脊，传入于髓，故令背高如龟之状，名曰龟背。终成痼疾，何以为治？
婴孩生后，百日之内，半岁以上，忽两眼胞红晕微起，面带青黯色，向夜烦啼，或
脸如胭脂，此伏热在内。亦有脸不红者，始因居胎之时，母受重惊，惊邪伤胎，递相传
袭，降生之后，复受热毒，或再有惊，有惊则有热，热气内蕴，形发于外，初发时散生
满面，状如水豆，脚微红而不壮，出没休息无定，次到颈项，赤如朱砂，名为惊丹。用
四圣散先洗其目，次百解散加五和汤同煎，与解惊热丹毒，牛蒡汤、当归散、三解散、黄
苓四物汤，皆可为治。如惊丹发至胸乳间，微有痰喘作搐，急宜宣热拔毒，免致内流，为
害不浅。五和汤加升麻、生干地黄，水、姜、灯心煎服，则自消除。仍用前数药调治，不
生他证，或投万安饮。
我曾论述这一病候，是由于风痰和停饮积聚在心胸部位，又感受风热之邪。肺为五脏六腑的华盖（覆盖诸脏的最高器官），位于膈肌之上，若水气泛溢，则肺气上浮；日久凝聚成痰，停滞于心胸，再加上风热在内发作，其外在证候表现为嘴唇红、面色赤、咳嗽且呼吸急促。导致胸骨高耸如同倒扣的手掌，名为龟胸。治疗方法应宽利肺气、化痰、通利膈膜，以清除肺经的痰饮。先用五苓散配合和宽气饮，加入姜汁、葱汤调匀后服用；其次用清肺饮、雄黄散、碧玉丸、如意膏进行治疗。如果投用上述药物后，病情好转却又复发并发生传变，出现两眼直视、痰涎上壅，兼有抽搐发作，那就难以治疗了。
至于龟背，是因为初生婴儿未满半周岁时，被强行过早令其坐立，客风吹袭背部脊柱，邪气传入骨髓，从而导致背部高耸如龟壳状，名为龟背。最终成为顽固性疾病，该如何治疗呢？
婴儿出生后百日之内，或半岁以上，忽然两眼眼睑红肿微起，面带青暗色，入夜烦躁啼哭，或者脸色如胭脂般红润，这是伏热蕴结在体内。也有脸色不红的，起因是在母体受孕期间，母亲遭受重大惊吓，惊邪损伤胎元，依次相传袭染，降生之后，又复受热毒，或者再次受到惊吓。有惊则生热，热气内蕴，表现于外形，初发时散布满面部，形状像水痘，脚部微红但不壮实，出没无常无定规，随后蔓延至颈项，红如朱砂，名为惊丹。先用四圣散清洗眼睛，再用百解散加五和汤同煎，用以解除惊热丹毒；牛蒡汤、当归散、三解散、黄芩四物汤，都可以用来治疗。如果惊丹发至胸乳之间，伴有轻微痰喘和抽搐，急需宣散热毒、拔除毒素，以免邪气内流，造成不小的危害。在五和汤中加入升麻、生干地黄，用水、生姜、灯心草煎服，则自然消除。仍然用前述几种药物调理治疗，不生其他病变，或者投用万安饮。
I have discussed this condition, which arises from the accumulation of wind-phlegm and retained fluid in the chest and heart region, compounded by an external contraction of wind-heat. The Lung is the canopy (the highest organ covering all other viscera) among the five zang organs, situated above the diaphragm. When water qi overflows, the Lung becomes hyperfluent; after a long period, it condenses into phlegm and stagnates in the chest and heart. Coupled with the internal emergence of wind-heat, the external manifestations include red lips, flushed face, coughing, and rapid breathing. This leads to the sternum protruding high like an inverted palm, a condition named Turtle Chest (Guixiong). The treatment method involves relaxing the Lung, resolving phlegm, and unblocking the diaphragm to eliminate phlegm-fluid in the Lung meridian. First, administer Wuling San (Five-Ingredient Poria Decoction) combined with Kuanqiang Qi Yin (Harmonizing and Broadening Qi Decoction), mixed with ginger juice and scallion decoction for oral administration. Subsequently, treat with Qingfei Yin (Lung-Clearing Drink), Xionghuang San (Realgar Powder), Biyu Wan (Jasper Pill), and Ruyi Gao (Ruyi Ointment). If, after administering these medicines, the disease recurs and transforms, presenting with fixed staring eyes, upward congestion of phlegm-saliva, and convulsions, it becomes difficult to treat.
As for Turtle Back (Guibei), it occurs when infants under half a year old are forced to sit too early. External wind attacks the spine, transmitting pathogenic factors into the marrow, causing the back to rise like a turtle shell, hence named Turtle Back. It ultimately becomes a chronic, stubborn disease; how should it be treated?
Within one hundred days after birth, or after six months of age, if an infant suddenly presents with slightly raised, reddish eyelids, a bluish-dark complexion, and nocturnal irritability and crying, or if the face resembles cinnabar, this indicates latent heat accumulating internally. In cases where the face is not red, the origin lies in severe fright suffered by the mother during pregnancy. Fright-pathogens damage the fetus and transmit sequentially. After birth, exposure to heat-toxins or further fright may occur. Fright generates heat; this heat accumulates internally and manifests externally. Initially, it appears scattered across the face, resembling water-filled vesicles, with slightly red but non-turgid bases, appearing and disappearing irregularly. It then spreads to the neck, becoming as red as cinnabar, named Jingdan (Fright Erythema). First, wash the eyes with Sisheng San (Four-Saints Powder). Then, decoct Bairen San (Hundred-Resolving Powder) together with Wuhe Tang (Five-Harmonies Decoction) to resolve fright-heat and erysipelas-like toxins. Niubang Tang (Arctium Decoction), Danggui San (Angelica Powder), Sansan Jie San (Three-Dispersal Resolving Powder), and Huangqin Siwu Tang (Scutellaria Four-Substance Decoction) can all be used for treatment. If Jingdan erupts between the chest and breasts, accompanied by slight phlegm-wheeze and convulsions, urgent measures to vent heat and extract toxins are required to prevent internal invasion, which would cause significant harm. Add Shengma (Cimicifugae Rhizoma) and Sheng Dihuang (Rehmanniae Radix Recens) to Wuhe Tang, decoct with water, fresh ginger, and Jiedixin (Centellae Herba), and administer orally; the condition will naturally subside. Continue调理 with the aforementioned medicines to prevent other complications, or alternatively, administer Wan'an Yin (Ten-Thousand-Peace Drink).
