娠妊在腹，如怀藏宝。服药所忌防其伤胎。医家举笔，留神不可孟浪草率。吾师程钟龄先生，同叶其秦先生
编成歌句，俾后人易于诵记。予略为之增补。此外，仍有信砒、水银、斑蝥、水蛭、蛇蜕、蜈蚣，一切毒物，虽非恒用
之品，或遇生毒别故，皆宜留心避之。
歌曰
乌头附子与天雄，牛黄巴豆并桃仁，芒硝大黄牡丹桂，牛膝藜芦茅茜根，槐角红花及皂角，三棱莪术薏
苡仁，干漆 茹瞿麦穗，半夏南星通草同，干姜大蒜马刀豆，延胡常山麝莫闻，黑丑槟榔同苏木，伤胎之药避
其凶。
此中有安胎止呕，不得不用半夏者，必用开水泡洗三次，以去燥烈之性，呕止即去。有热病闭结，伤寒传
经入腑而必欲大黄者，有中寒于阴，必欲姜桂者。《内经》曰∶有故无殒，亦无殒也。衰其大半而止。此即
有病则病当之，乃从权也。然必不得已而用之，不可过剂。而用药中，亦必有顾胎之味。予意总之胎前有病
症，重在保胎；产后有病症，重在温补。此至稳至当之理。
产后有病，重在温补，乃云至稳至当之理。试问∶仲景云产后有三病，一者病 ，二者病郁冒，三者大
便难，此三证乃血虚火旺，津液不足，亦可以温补治之乎？吾尝谓立言不慎，实贻害于苍生，此类是也。

妊娠期间，胎儿在腹中，如同怀抱珍宝。服药时必须忌讳，以防损伤胎元。医生提笔开方时，务必小心谨慎，不可轻率草率。我的老师程钟龄先生与叶其秦先生共同编写了歌诀，以便后人易于诵读记忆。我对此略作增补。此外，还有信砒、水银、斑蝥、水蛭、蛇蜕、蜈蚣等一切毒物，虽然这些并非日常常用之品，但若遇到特殊病因或急症，也应当留心避免使用。
歌诀说：
乌头、附子与天雄，牛黄、巴豆并桃仁，芒硝、大黄、牡丹皮、肉桂，牛膝、藜芦、白茅根，槐角、红花及皂角，三棱、莪术、薏苡仁，干漆、姜茹、瞿麦穗，半夏、南星、通草同用，干姜、大蒜、马刀豆，延胡索、常山、麝香莫沾闻，黑丑、槟榔同苏木，这些都是伤胎的药物，必须避开以免凶险。
其中有些情况需要安胎止呕，不得不使用半夏的，必须用开水浸泡清洗三次，以去除其燥烈之性，呕吐停止后即停用。有热病导致便秘，伤寒传经入腑而必须使用大黄的，有中寒于阴证而必须使用干姜、肉桂的。《黄帝内经》说：“有病则病当之，亦无殒也。”（意为有病邪存在，药物作用于病邪，不会伤害人体），当病邪消退大半时就应停药。这就是“有病则病当之”的道理，属于权宜之计。然而，如果不得已而使用这些药物，不可过量。且在用药过程中，也必须兼顾保护胎元的药物。我的观点总之是：产前有病证，重在保胎；产后有病证，重在温补。这是最稳妥恰当的道理。
产后有病，重在温补，说是至稳至当之理。试问：张仲景说产后有三病，一是痉病，二是郁冒，三是大便难，这三种证候乃是血虚火旺、津液不足所致，难道也可以用温补法来治疗吗？我曾说立言不慎，实在贻害百姓，此类言论就是例子。
（徐灵胎评注）
During pregnancy, the fetus resides in the abdomen like a hidden treasure. Medications must be avoided or used with extreme caution to prevent damage to the fetus. Physicians must exercise care and prudence when prescribing, avoiding rashness or negligence. My teacher, Mr. Cheng Zhongling (Cheng Yanqin), along with Mr. Ye Qiqin, compiled a mnemonic verse to facilitate memorization for future generations. I have made slight additions to it. Furthermore, substances such as Realgar (Xin Pi), Mercury (Shui Yin), Mustard Beetle (Ban Mao), Leech (Shui Zhi), Snake Slough (She Tui), and Centipede (Wu Gong) are all toxic materials. Although these are not commonly used daily, one should remain vigilant and avoid them unless absolutely necessary due to specific pathological conditions.
The verse states:
Aconite Root (Wu Tou), Prepared Aconite Child (Fu Zi), and Heavenly Hero (Tian Xiong);
Cochlearia Rhizome (Niu Huang - *Note: Contextually likely refers to Bear Bile or similar potent substance, but literal translation of Niu Huang is Gallbladder Calculus Bovis*), Croton Seed (Ba Dou), and Peach Kernel (Tao Ren);
Mirabilite (Mang Xiao), Rhubarb (Da Huang), Peony Root (Mu Dan Pi), and Cinnamon Twig (Gui Zhi);
Achyranthes Root (Niu Xi), Veratrum Rhizome (Li Lu), and White Imperata Rhizome (Bai Mao Gen);
Sophora Fruit (Huai Jiao), Safflower (Hong Hua), and Gleditsia Sinensis Fruit (Zao Jiao);
Bamboo Shavings (San Leng), Curcuma Rhizome (E Zhu), and Coix Seed (Yi Yi Ren);
Dried Lacquer (Gan Qi), Ginger Root (Jiang Ru - *likely typo for Jiang or similar*), and Agrostemma Seed (Qu Mai Sui);
Pinellia Tuber (Ban Xia), Arisaema Rhizome (Nan Xing), and Thladiantha Root (Tong Cao) used together;
Dried Ginger (Gan Jiang), Garlic Bulb (Da Suan), and Horse Bean (Ma Dao Dou);
Cyperus Rhizome (Yan Hu Suo), Hedyotis Herb (Chang Shan), and Moschus (She Xiang) must not be heard of;
Dark Morning Glory Seed (Hei Chou), Areca Nut (Bing Lang), and Sapwood of Paulownia (Su Mu).
These are drugs that harm the fetus; avoid their ominous effects.
In certain cases, such as stabilizing the fetus and stopping vomiting, Pinellia Tuber (Ban Xia) may be indispensable. If used, it must be soaked and washed three times with boiling water to remove its drying and irritating properties, and discontinued once vomiting ceases. In cases of heat disease with constipation, or Taiyang disease transmitting into the Fu organs requiring Rhubarb (Da Huang), or in cases of Cold damaging the Yin requiring Dried Ginger (Gan Jiang) and Cinnamon Twig (Gui Zhi), the *Neijing* states: "If there is pathology, the pathology bears the brunt; there will be no injury [to the healthy qi]." Treatment should cease when the pathogenic factor has been reduced by more than half. This follows the principle that "when there is disease, the disease absorbs the drug's action," which is a flexible approach. However, if these drugs must be used out of necessity, they should not be overdosed. Moreover, medications that protect the fetus should always be included. My general view is: for antenatal diseases, the priority is protecting the fetus; for postnatal diseases, the priority is warming and tonifying. This is the most stable and appropriate principle.
It is said that for postnatal diseases, warming and tonifying is the most stable principle. Let us ask: Zhang Zhongjing stated that there are three common postpartum diseases: one is Spasm (Jing), two is Depression and Vertigo (Yu Mao), and three is Difficulty in Defecation (Da Bian Nan). These three syndromes result from Blood deficiency, Hyperactive Fire, and insufficiency of Body Fluids. Can they truly be treated with warming and tonifying methods? I have often remarked that imprudent statements cause harm to the people, and this type of reasoning is an example.
