夫医之道微矣，医及婴童抑又微矣。盖男妇之疾，感于七情，当其感而成疾也，各能自察其杞 ，各能自周其调折，
即求医而功与医各操其半，故治之易。在幼儿，月内为襁褓，及期曰婴，三岁为孩，七龆、八龀、十岁稚子，十六岁为
童。婴孩则不能言，言亦不能悉；在童则能言，言而不能自摄。婴童之病，独听命于医，而医独为众婴之母，治未易易
也。仓公曰∶医者意也。旨在斯言，意殆为婴儿司命钥乎！顾身之所及，意斯及。身所不及则意穷，意所不及则药穷。
惟是使药不穷于意，意不穷于身，非无穷方术不可也。昔韩子原道，而所喻于薪尽火传，安见夫火传之方脉，即不尽之
薪耶。余家世业岐黄迄今九叶矣。祖孙父子相授受，不啻三折肱矣。其间大小方脉，多所研究，而尤于幼科为专门。纶
潜心觅古，凝志探今，备考先贤之论，附察有验之方，积以岁月，汇成斯帙。一曰痘痧心法；一曰婴童类萃；续以外科
经验诸方，总名曰王氏家抄。遇病则按症寻方，审候则随宜投剂，傥亦火传之遗旨乎 不揣愚陋，悉授梓人，以公吾党，
为幼儿三指之助。俟高明复加删斥正，未必无小补云。
天启二年菊月怡冈王大纶跋
医学的道理是精微的，而针对婴幼儿的医疗则更加精微。因为成年男女的疾病，多由七情（喜、怒、忧、思、悲、恐、惊）引起，在感受病邪并发病时，他们能够自我察觉身体的不适，也能自行周全地调整调养。即使求医治疗，疗效也是医生与患者各占一半，所以治疗相对容易。而对于幼儿，出生一个月内称为襁褓，满周岁称为婴，三岁称为孩，七八岁换牙时期称为龆龀，十岁称为稚子，十六岁称为童。婴儿和幼儿不能说话，即便能说话也不能表达清楚；儿童虽然能说话，却不懂得自我照顾。婴幼儿的疾病，完全听命于医生，医生独自承担着众多婴儿母亲般的责任，因此治疗并非易事。西汉名医仓公说：“医生的关键在于意念。”这句话的深意在于，意念大概是掌管婴儿生命的关键钥匙吧！然而，意念的作用范围受限于身体所能感知的范围，身体无法感知到的地方，意念也就穷尽了；意念无法触及的地方，药物的作用也就局限了。只有使药物不局限于意念，意念不局限于身体感官，才需要运用无穷无尽的方术。过去韩愈在《原道》中用“薪尽火传”来比喻道统的传承，难道这不正像通过脉诊传承医术，如同传递永不熄灭的火种一样吗？我家世代从事中医行业，至今已有九代。祖孙父子之间相互传授医术，正如俗语所说“三折肱知为良医”，经验丰富。其间对内科各科多有研究，尤其以儿科为专门领域。我（王大纶）潜心搜寻古籍，专注探究今人经验，考证先贤的论述，附上经过验证有效的方剂，历经岁月积累，汇集成此书。全书分为两部分：一是《痘痧心法》，二是《婴童类萃》；随后附上外科经验诸方，总名为《王氏家抄》。遇到疾病便根据症状寻找方剂，审察病情则酌情投药，这或许就是“薪尽火传”遗旨的体现吧？我不自量力，愚昧浅陋，将书稿交付刻印工匠，公之于众，作为幼儿诊疗的辅助。等待高明之士加以删改指正，未必没有小小的补益。
天启二年（1622年）农历九月 怡冈 王大纶 跋
The principles of medicine are subtle, and the practice of medicine for infants and children is even more so. The illnesses of adult men and women are often caused by the Seven Emotions (joy, anger, worry, thought, sadness, fear, and fright). When they contract an illness, they can usually perceive their own discomfort and adjust their lifestyle and care accordingly. Even when seeking medical treatment, the therapeutic effect is shared equally between the physician and the patient; thus, treatment is relatively easier. In contrast, infants within one month of birth are called *qiangbao* (swaddled infants); those at one year old are called *ying*; three-year-olds are called *hai*; children aged seven or eight who are losing teeth are called *taochen*; ten-year-olds are called *zizi*; and sixteen-year-olds are called *tong*. Infants and toddlers cannot speak, or if they can, they cannot express themselves fully; older children can speak but lack the ability to self-care. Illnesses in infants and children depend entirely on the physician, who acts as a surrogate mother for many infants; therefore, treatment is not easy. Cang Gong, a famous physician of the Western Han Dynasty, said, "The essence of medicine lies in intention." The profound meaning of this statement is that intention serves as the key to managing the life of an infant. However, the scope of intention is limited by what the body can sense; where the body cannot sense, intention reaches its limit; where intention cannot reach, the efficacy of herbs is also limited. Only by employing infinite methods and formulas can one ensure that herbs are not limited by intention, and intention is not limited by physical sensation. In the past, Han Yu, in his essay *Yuan Dao*, used the metaphor of "passing the fire from one torch to another until the original fuel is exhausted" to describe the transmission of the Dao. Is this not analogous to the transmission of pulse diagnosis and medical skills, like a fire that never goes out? My family has been engaged in traditional Chinese medicine for nine generations. Physicians have passed down knowledge from grandfathers to sons and fathers to sons, accumulating experience akin to the saying, "Three broken arms make a good physician." We have studied various internal medicine specialties extensively, with a particular focus on pediatrics. I, Wang Dalun, have devoted myself to searching ancient texts and exploring contemporary practices, verifying the theories of sages, and compiling verified effective prescriptions. After years of accumulation, this volume was compiled. It consists of two main parts: *Xinfa of Smallpox and Measles* and *Collected Essentials for Infants and Children*, followed by empirical formulas for external diseases, collectively titled *Wang Family Manuscripts*. When encountering a disease, one selects a formula based on symptoms; upon examining the condition, one administers medication appropriately. This may be considered a continuation of the legacy of "transmitting the fire." Presuming my ignorance and shallowness, I have submitted this manuscript to the printers to share it with my peers, hoping it will assist in the examination of young children's pulses. I await the corrections and deletions by experts, believing it may offer some minor benefit.
Dedicated by Wang Dalun of Yigang in the ninth lunar month of the second year of Tianqi (1622)
