曰病者是也。凡人家小儿，勿与怀孕妇人抱之，如胎禀强者则无碍，怯弱者犯之即成 病，如客忤之类。治

巢氏云∶小儿被 病者，妇人怀胎孕，有 神导其腹中，胎嫉妒小儿，致令此病。其状微微下利，寒热往
来，毛发 ，情思不悦也。《千金》论 者，小儿鬼也。凡妇人先有小儿，未能行而母继有胎妊，令儿渐渐

薛东明治王生子，周岁，忽不乳食，肌肉消尽，医疑为疳。薛曰∶此相思症也。众皆嗤笑之。薛命取平时
玩弄之物，悉陈于前，有小木鱼儿，一见遂笑，疾遂已。（《江南通志》。）
万密斋治胡三溪子，岁半，日入后，忽啼不止，时七夕也。三溪招万饮，已而报啼甚，请入视之，无病也。
饮未竟，儿啼甚，人以儿故，意不乐。三溪强再视，细察之，实无病。无病而哭，必心有所欲，不能言也。乃
问曰∶儿今日所喜弄者何物？乳母曰∶马鞭子。即令取至，乃笑而持之，击其乳母，不复哭矣，于是畅饮而罢。
明日有问者，曰∶此小儿害相思病也，可以为案。
一儿半岁，忽日惨然不乐，昏睡不乳。万曰∶形色无病，将谓外感，则无风寒之症，将谓内伤，则无乳食
之症。此儿莫有所思，思则伤脾，乃昏睡不乳也。其父母悟云∶有一小 相伴者，吾使他往，今三日矣。乳母
亦云∶自小 去后，便不欣喜，不吃乳。父急命呼之归，儿见其童嬉笑。父曰∶非翁妙术，不能知也。
万密斋诊治一名两岁的小儿，经常排出绿色稀便，身体消瘦得像鬼一样。医生将其作为疳积病治疗，但无效。万密斋说：“这不是疳积，而是胎气所害，这种病名叫‘妒病’（因嫉妒胎气而致病）。一般家中的小儿，不要让怀孕的妇女抱他，如果胎儿禀赋强健则无碍，若禀赋怯弱，被孕妇抱了就会患上此病，类似于客忤（外邪侵袭所致惊悸）。治疗时，只需补益其脾胃，等那个孕妇生下孩子后，这个患儿自然就会痊愈。用肥儿丸主治。钱乙的肥儿丸组成：黄连、神曲、木香、槟榔、肉豆蔻、使君子、麦芽，用面糊制成丸药，大小如麻子，每次服用三五十丸。
巢元方说：小儿患妒病者，是因为妇人怀有身孕，腹中有神灵引导，胎儿嫉妒小儿，导致发生此病。症状表现为轻微腹泻，寒热往来，毛发枯黄稀疏，神情抑郁不乐。《千金方》论述此类病症，认为是小儿中邪。凡是妇人先有一个孩子，还不会走路时，母亲又再次怀孕，导致原来的孩子渐渐消瘦，骨立形销，毛发稀黄不长，时常出现高热，大便不调，这就是妒病，又称继病。治法应当用紫霜丸攻下，再用乳益散补益。（紫霜丸组成：代赭石醋淬七次、赤石脂各一两，杏仁五十枚，巴豆去皮去油三十枚，蒸饼为丸，大小如粟米。一岁的服五丸，百日内的服三丸，用乳汁调服。）让小儿断奶后即能安宁。消乳丸、异功散也是极好的方剂。如果有其他妇女怀孕，却抱着别人的婴儿，也会出现这种症状，治疗方法相同。若有热象，用龙胆汤。
薛己诊治王家的儿子，周岁大，突然不吃奶和食物，肌肉消尽，医生怀疑是疳积。薛己说：“这是相思症。”众人都嗤笑他。薛己命人取来孩子平时玩耍的物品，全部陈列在面前，其中有一个小木鱼儿，孩子一见就笑了，疾病随即痊愈。（出自《江南通志》。）
万密斋诊治胡三溪的儿子，一岁半，傍晚后忽然啼哭不止，当时正值七夕。胡三溪邀请万密斋饮酒，过了一会儿报告说孩子哭得很厉害，请万密斋进去查看，发现并无疾病。酒还没喝完，孩子哭得更凶，旁人因为孩子的缘故心情不悦。胡三溪强请万密斋再次查看，仔细检查后，确实没有病。没病而哭，一定是心里有所想要，但不能表达。于是问道：“孩子今天喜欢玩弄什么东西？”乳母说：“马鞭子。”立即让人拿来，孩子笑着拿过马鞭，敲打乳母，就不再哭了，于是大家畅饮而散。第二天有人问起此事，万密斋说：“这个小儿害的是相思病，可以作为医案记录。”
另一个半岁的孩子，忽然面色惨淡不快乐，昏睡不吃奶。万密斋说：“形色上没有病征，说是外感，却没有风寒的症状；说是内伤，却没有乳食停滞的症状。这孩子必定有所思念，思虑伤脾，所以昏睡不吃奶。”他的父母醒悟道：“有一个小同伴陪伴他，我让他出去了，已经三天了。”乳母也说：“自从小同伴离开后，孩子就不高兴，不吃奶。”父亲急忙派人叫同伴回来，孩子见到同伴嬉戏欢笑。父亲说：“如果不是您高明的医术，不能知晓病因。”
Wan Mizhai treated a two-year-old child who frequently passed green watery stools and was emaciated like a ghost. Physicians treated it as *gan* syndrome (malnutrition syndrome) without effect. Wan said, "This is not *gan*, but harm caused by fetal qi, named 'Du Bing' (Disease of Fetal Jealousy). Generally, children in households should not be held by pregnant women; if the fetus has strong constitution, there is no harm, but if weak, contact with the pregnant woman will cause this disease, similar to *Ke Wu* (Sudden fright from external influences). Treatment involves merely tonifying the Spleen and Stomach; once that pregnant woman gives birth, the child will naturally recover. Use Fei'er Wan (Fetus-Enriching Pill) as the main prescription. Qian's Fei'er Wan consists of: Huanglian (Coptidis Rhizoma), Shenqu (Massa Medicata Fermentata), Muxiang (Aucklandiae Radix), Binglang (Arecae Semen), Roudoukou (Myristicae Semen), Shijunzi (Quisqualis Fructus), Maiya (Hordei Fructus Germinatus), made into pills with wheat paste, size of hemp seeds, 30-50 pills per dose.
Chao Yuanfang stated: Children suffering from Du Bing are affected because a pregnant woman carries a fetus whose spirit guides the womb; the fetus becomes jealous of the child, causing this illness. Symptoms include slight diarrhea, alternating chills and fever, sparse and yellowish hair, and depressed mood. The *Qianjin Fang* discusses such cases as possession by spirits. When a woman first has a child who cannot yet walk, and then becomes pregnant again, the older child gradually becomes emaciated, bony, with sparse yellow hair that does not grow, experiencing frequent high fevers and irregular bowel movements; this is Du Bing, also called Ji Bing (Successive Disease). The method requires using Zishuang Wan (Purple Frost Pill) to purge, followed by Buyi San (Breast-Nourishing Powder) to tonify. (Zishuang Wan consists of: Daizhe Shi (Hematitum) quenched in vinegar seven times, Chishizhi (Halloysitum Rubrum), each one tael; Xingren (Pruni Armeniaci Semen), fifty pieces; Badou (Crotonis Fructus), peeled and oil-extracted, thirty pieces; formed into pills with steamed bread dough, size of millet grains. One-year-olds take five pills; infants within 100 days take three pills, administered with breast milk.) The child will be at peace upon weaning. Xiaoru Wan (Milk-Digesting Pill) and Yigong San (Extraordinary Power Powder) are also excellent formulas. If another pregnant woman holds someone else's infant, similar symptoms may occur, treated identically. If heat signs are present, use Longdan Tang (Gentian Decoction).
Xue Ji treated the son of Mr. Wang, aged one year, who suddenly refused milk and food, with muscles wasting away. Physicians suspected *gan* syndrome. Xue said, "This is Xiangsi Syndrome (Lovesickness)." Everyone laughed at him. Xue ordered the retrieval of objects the child usually played with, displaying them before him. Upon seeing a small wooden fisher toy, the child smiled, and the illness immediately resolved. (*Jiangsu Tongzhi*).
Wan Mizhai treated Hu Sanxi's son, aged one and a half years, who cried incessantly after sunset on the evening of the Qixi Festival. Hu invited Wan to drink wine. Later, he reported that the child was crying severely and asked Wan to examine him. Wan found no illness. Before the wine was finished, the child cried even louder. Others were displeased due to the child's distress. Hu insisted Wan examine the child again. After careful examination, Wan confirmed there was truly no illness. Crying without illness implies the heart desires something it cannot express. Wan asked, "What object did the child wish to play with today?" The wet nurse replied, "A horsewhip." It was fetched immediately. The child took it laughing, tapped the wet nurse with it, and stopped crying. They drank happily and concluded the gathering. The next day, when asked about the case, Wan said, "This child suffered from Lovesickness; it can serve as a medical record."
Another infant, six months old, suddenly appeared gloomy, slept excessively, and refused milk. Wan said, "There are no pathological signs in appearance or color. If considered an external contraction, there are no wind-cold symptoms; if considered internal injury, there are no symptoms of milk or food stagnation. This child must be preoccupied with thoughts. Overthinking injures the Spleen, leading to lethargy and refusal of milk." The parents realized, "We sent away a young companion who used to stay with him for three days." The wet nurse added, "Since the companion left, the child has been unhappy and refuses milk." The father urgently ordered the companion to be brought back. Seeing the companion playing and laughing, the child recovered. The father said, "Without your profound medical skill, this cause could not have been known."
