鸡肉合糯米食，令子生寸白虫。食犬肉，令子无声。鲤鱼同鸡子食，令子生疳，多
疮。食兔肉，令子缺唇。食羊肝，令子多厄。食鳖肉，令子项短缩颈。鸡子与桑堪
同食，令子倒生，心寒。鲜鱼同田鸡食，令子喑哑。雀肉同豆酱食。令子面生 黑子。
食螃蟹，令子横生。食生姜，令子多指。食冰浆，令绝产。食雀肉饮酒，令子多淫无
耻。食慈菇，消胎气。食驴马肉，过月难产。豆酱合藿香食之，堕胎。食山羊肉，
令子多病。食鳅无鳞鱼，难产。食诸般菌，生子惊风而夭。食雀脑，令子患雀目。
歌曰∶ 斑水蛭及虻虫，乌头附子配天雄，野葛水银并巴豆，牛膝薏苡与蜈蚣，三棱
代赭芫花麝，大戟蛇脱黄雌雄，牙硝芒硝丹皮桂，槐花牵牛皂角同，半夏南星与通草，瞿麦
干姜桃仁通， 砂干漆蟹脚爪，地胆茅根莫用好。（此药外，或有未尽者，可以类推）
便产须知云∶勿乱服药，勿过饮酒，勿妄针灸，弗向非常地便；勿举重登高涉险，心有
大惊，犯之产难，子必癫痫；勿多睡卧，时时行步；勿劳力过伤，使肾气不足，生子解颅，脑破
下合；衣毋太温，食毋太饱，若脾胃不和，荣卫
虚怯，子必羸瘦多病。自家及邻家修造动土，犯其胎气，令子破形殒命。刀犯者，形必伤；泥
犯者，窍必塞；打击者，色青黯；紧缚者，相拘挛，有此等，验如影响，切宜避之。

歌诀说：斑蝥、水蛭及虻虫，乌头、附子配天雄，野葛、水银并巴豆，牛膝、薏苡仁与蜈蚣，三棱、代赭石、芫花、麝香，大戟、蛇蜕、黄雌雄（指黄狗或黄猫等动物药，此处泛指峻烈之品），牙硝、芒硝、丹皮、桂枝，槐花、牵牛子、皂角同用，半夏、南星与通草，瞿麦、干姜、桃仁共用，砂仁、干漆、蟹脚爪，地胆、茅根不要使用。（除了这些药物外，或许还有未尽列举的，可以类推避免。）
《便产须知》中说：不要乱服药，不要过量饮酒，不要随意针灸，不要在非正常地点分娩；不要举重、登高涉险，心中不要有大惊恐，触犯这些会导致难产，孩子必定患癫痫；不要长时间睡卧，要时常行走；不要过度劳累伤身，致使肾气不足，导致胎儿出生时囟门不合（解颅）、脑部破裂下陷；衣着不要太温暖，饮食不要太饱足，如果脾胃不和，营卫虚弱怯弱，孩子必定瘦弱多病。自家及邻居家修造动土，触犯其胎气，会导致胎儿畸形甚至死亡。被刀兵所犯者，形体必受伤；被泥土所犯者，七窍必闭塞；被打击者，肤色青暗；被紧缚者，肢体拘挛抽搐，有这些情况，验证灵验如影随形，务必避开。

(Besides these medicines, there may be others not fully listed, which can be inferred by analogy.)
"Bi Chan Xu Zhi" (Essentials for Childbirth) states: Do not take medicines indiscriminately, do not drink alcohol excessively, do not perform acupuncture and moxibustion arbitrarily, and do not give birth in unusual places; do not lift heavy objects, climb high, or venture into danger, and avoid great fright in the mind, as violating these will cause difficult labor, and the child will surely suffer from epilepsy; do not sleep and lie down too much, walk frequently; do not overexert yourself and injure your body, causing insufficiency of Kidney Qi, which results in the child being born with open fontanelle (Jie Lu) and sunken brain; clothing should not be too warm, food should not be too filling; if the Spleen and Stomach are disharmonious, and Ying and Wei (Defensive and Nutritive Qi) are weak and deficient, the child will surely be emaciated and prone to illness. Construction and earth-moving activities at home or by neighbors, if they offend the fetal qi, may cause fetal deformity and death. Offended by blades, the form will surely be injured; offended by mud, the orifices will surely be blocked; struck, the complexion will be dark blue; tightly bound, the limbs will be contracted and spasmodic. For such occurrences, verification is as immediate as shadow following form; one must strictly avoid them.
