治产难，不可早服，必胎衣破后，小儿头至产门者，然后服之。
野党参（一两） 当归（一两） 生赭石（二两，轧细）
用卫足花子炒爆一钱作引，或丈菊花瓣一钱作引皆可，无二物作引亦可。
或疑赭石乃金石之药，不可放胆重用。不知赭石性至和平，虽重坠下行，而不伤气血。况有党参一两以
补气，当归一两以生
血。且以参、归之微温，以济赭石之微凉，温凉调和愈觉稳妥也。矧产难者非气血虚弱，即气血壅滞，不能下
行。人参、当归虽能补助气血，而性皆微兼升浮，得赭石之重坠，则力能下行，自能与赭石相助为理，以成催
生开交骨之功也。至于当归之滑润，原为利产良药，与赭石同用，其滑润之力亦愈增也。
族侄妇，临盆两日不产。用一切催生药，胎气转觉上逆。为制此汤，一剂即产下。
一妇人，临产交骨不开，困顿三日，势甚危急。亦投以此汤，一剂而产。自拟得此方以来，救人多矣。放
胆用之，皆可随手奏效。
附∶卫足花即葵花，其子即冬葵子。缘此花若春日早种，当年即可结子。而用以催生，则季夏种之，经冬
至明年结子者尤效，故名曰冬葵子。今药坊所鬻者，皆以丈菊子为冬葵子，殊属差误。盖古之所谓葵，与俗所
谓向日葵者原非一种。古所谓葵即卫足花，俗呼为守足花者是也。因此花先生丛叶，自叶中心出茎，茎之下边
尽被丛叶卫护，故曰卫足。茎高近一丈，花多红色、与木槿相似，叶大如木芙蓉。此为宿根植物，季夏下种，
至次年孟夏始开花，结实大如钱，作扁形，其中子如榆荚，为其经冬依然发生，故其结之子名为冬葵子。须于
鲜嫩之时采取，则多含蛋白质，故能有益于人。《圣惠方》谓采其子阴干，是当鲜嫩之时采而阴干之也。若过
老则在科上自干，而无事阴干矣。又有一种，二、三月下种，至六月开花，其下无丛生之叶，不能卫足，而其
茎、叶、花皆与葵无异，其治疗之功效亦大致相同，即药品中之蜀葵。《本草纲目》谓花之白者治 疟，是卫
足葵与蜀葵皆治疟也。
至于俗所谓向日葵者，各种本草皆未载，惟《群芳谱》载之，本名丈菊，一名西番葵，一名迎阳葵，且谓
其性能堕胎。然
用其堕胎之力以催生，则诚有效验，是以大顺汤用其花瓣作引也。向日葵茎长丈许，干粗如竹，叶大如 ，花
大如盘盂，单瓣黄色，其花心成窠如蜂房。迨中心结子成熟，而周遭花瓣不凋枯。其子人恒炒食之，知其无毒，
且知其性滑，曾单用以治淋甚效。后与鸦胆子同用（鸦胆子去皮四十粒，用丈菊子一两炒捣，煎汤送下）治花
柳毒淋，亦甚效，然不知其能治疟也。近阅《绍兴医药学报》载卢××述葵能医疟一节，则丈菊诚可列于药品矣。
丈菊花英，催生之力实胜于子，曾见有单用丈菊花英催生，服之即效者，惜人多不知耳。至于用卫足子催生，
当分老嫩两种。鲜嫩卫足子，须用数两捣烂煮汁服，若用老者，当用两许微火炒裂其甲，煎汤饮之。
治疗难产，不能过早服用，必须等到胎膜破裂、胎儿头部到达产门时，然后才能服用。
野党参（一两） 当归（一两） 生赭石（二两，碾碎）
用卫足花子炒爆一钱作为药引，或者用丈菊花瓣一钱作为药引都可以，如果没有这两样东西做药引也可以。
有人怀疑赭石属于金石类药物，不敢大胆重用。不知道赭石的性质非常平和，虽然具有重坠下行的特性，但不会损伤气血。况且有一两党参来补气，一两当归来生血。并且利用党参、当归的微温之性，来调和赭石微凉的属性，温凉调和后显得更加稳妥。何况难产的原因，不是气血虚弱，就是气血壅滞，导致胎儿不能下行。人参、当归虽然能补助气血，但其药性都略微带有升浮的特点，得到赭石的重坠之性，就能使药力下行，自然能与赭石相辅相成，共同起到催生和开启交骨（耻骨联合）的作用。至于当归的滑润特性，原本就是利于生产的良药，与赭石同用，其滑润之力也会更加增强。
族侄的妻子，临盆两天未能分娩。使用各种催生的药物后，胎气反而觉得上逆。于是为她配制了这方汤剂，服用一剂后即顺利生产。
有一位妇人，临产时交骨不开，困顿三天，形势非常危急。也投以此汤，服用一剂后就分娩了。自从拟定这个方子以来，救的人很多。放心大胆地使用，都能随手取得疗效。
附注：卫足花即葵花，它的种子就是冬葵子。因为这种花如果春天早种，当年就可以结籽。而用来催生时，则在季夏种植，经过冬天到明年结出的种子效果尤其好，所以名叫冬葵子。现在药店出售的，都是用丈菊子当作冬葵子，这确实是有差错的。大概古代所说的葵，与民间所说的向日葵原本不是一种。古代所说的葵就是卫足花，俗称守足花的就是它。因为这种花先长出丛生的叶子，从叶子中心抽出茎，茎的下部都被丛叶护卫着，所以叫卫足。茎高近一丈，花多红色，与木槿相似，叶子大如木芙蓉。这是宿根植物，季夏下种，到次年孟夏才开花，果实大如铜钱，呈扁形，其中的种子像榆荚一样，因为它经过冬天依然发芽，所以结出的种子名为冬葵子。必须在鲜嫩的时候采摘，这样含有较多的蛋白质，所以对人有益。《圣惠方》说采集它的种子阴干，就是指在鲜嫩的时候采摘并阴干。如果过老，就在枝头自然干枯，就不需要阴干了。又有一种，二、三月下种，六月开花，下面没有丛生的叶子，不能护卫茎足，而其茎、叶、花都与葵无异，其治疗功效也大致相同，这就是药品中的蜀葵。《本草纲目》说白色的花治疟疾，说明卫足葵与蜀葵都能治疟疾。
至于民间所说的向日葵，各种本草书中都没有记载，只有《群芳谱》记载了它，本名丈菊，又名西番葵、迎阳葵，并且说它具有堕胎的性能。然而用它堕胎的力量来催生，确实有效验，所以大顺汤用其花瓣作为药引。向日葵茎长约一丈，干粗如竹，叶大如...（原文此处似有缺字或比喻），花大如盘盂，单瓣黄色，花心成窝状如蜂房。等到中心结籽成熟，周围的花瓣却不凋枯。人们经常炒食它的种子，知道它无毒，且知道它的性质滑利，曾单独用来治疗淋证非常有效。后来与鸦胆子同用（鸦胆子去皮四十粒，用丈菊子一两炒捣，煎汤送服）治疗花柳毒淋，也非常有效，然而不知道它能治疟疾。最近阅读《绍兴医药学报》载卢××讲述葵能医疟的一节，那么丈菊确实可以列入药品之中了。丈菊花蕾，催生的力量实际上胜过种子，曾见有人单独用丈菊花蕾催生，服用后立即见效，可惜很多人不知道罢了。至于用卫足子催生，应当分为老嫩两种。鲜嫩的卫足子，需要用数两捣烂煮汁服用；如果用老的，应当用一两左右微火炒裂其外壳，煎汤饮用。
To treat dystocia (difficult labor), it should not be taken too early; it must only be administered after the fetal membranes have ruptured and the infant's head has reached the birth canal.
Wild Codonopsis Radix (Dangshen, 30g)
Angelicae Sinensis Radix (Danggui, 30g)
Raw Hematitum (Zhesishi, 60g, finely crushed)
Use one qian (approx. 3.75g) of fried seeds from Helianthus annuus (Sunflower seeds, known as Weizu Hua Zi) as a guiding drug (Yin); alternatively, one qian of Helianthus annuus petals can be used as a guiding drug. If neither is available, it may also be used without a guiding drug.
Some may doubt that Hematitum, being a mineral substance, should not be boldly used in heavy doses. However, Hematitum has a very mild nature; although it is heavy and directs qi downward, it does not damage qi and blood. Moreover, with one liang (approx. 30g) of Codonopsis to tonify qi and one liang of Angelicae Sinensis Radix to generate blood, the slight warmth of Codonopsis and Angelica balances the slight coolness of Hematitum, making the combination even more secure. Furthermore, dystocia is either due to deficiency of qi and blood or stagnation of qi and blood, preventing descent. Although Ginseng Radix et Rhizoma (Renshen) and Angelicae Sinensis Radix can supplement qi and blood, their properties are slightly ascending and floating. With the heavy, descending nature of Hematitum, their force is directed downward, naturally assisting each other to achieve the effect of inducing labor and opening the pubic symphysis (Jiaogu). As for the slippery and moistening property of Angelicae Sinensis Radix, it is originally an excellent medicine for facilitating childbirth; when used with Hematitum, its slippery and moistening power is further enhanced.
The wife of my clan's nephew labored for two days without delivering. After using various labor-inducing medicines, the fetal qi felt reversed upward. I prepared this decoction for her, and she delivered after taking just one dose.
A woman experienced failure of the pubic symphysis to open during labor, suffering for three days in a critical condition. This same decoction was administered, and she delivered after one dose. Since formulating this prescription, I have saved many people. Use it boldly, and it will invariably produce immediate results.
Appendix: Weizu Hua refers to the sunflower, and its seed is Dong Kui Zi (Semen Malvae). Because if this flower is planted early in spring, it bears fruit in the same year. However, when used to induce labor, those planted in mid-summer and harvested after winter into the following year are particularly effective, hence the name Dong Kui Zi (Winter Okra Seed). Currently, pharmacies sell Semen Helianthi (Sunflower seeds) as Dong Kui Zi, which is a significant error. The "Kui" mentioned in ancient texts is not the same as the common sunflower. The ancient "Kui" is Weizu Hua, commonly called Shou Zu Hua (Guarding Foot Flower). This plant first produces clustered leaves, from the center of which the stem emerges; the lower part of the stem is protected by the clustered leaves, hence the name Weizu (Guarding Foot). The stem is nearly one zhang (approx. 3.3 meters) high, flowers are mostly red and similar to Hibiscus syriacus, and leaves are large like Hibiscus mutabilis. It is a perennial plant; sown in mid-summer, it blooms in early summer of the next year. The fruit is coin-sized and flat, containing seeds like elm samaras. Because it sprouts even after winter, the seed is named Dong Kui Zi. It must be harvested when tender to retain high protein content, thus benefiting humans. *Sheng Hui Fang* states to harvest the seeds and dry them in the shade, meaning harvesting while tender and drying in the shade. If left too long, they dry on the stalk, making shade-drying unnecessary. Another variety is sown in February or March, blooms in June, lacks clustered leaves at the base to guard the stem, but its stem, leaves, and flowers are identical to Kui, and its therapeutic effects are largely the same; this is Shu Kui (Malva verticillata). *Ben Cao Gang Mu* states white flowers treat malaria, indicating both Weizu Kui and Shu Kui can treat malaria.
As for the common sunflower, it is not recorded in various materia medica, only in *Qun Fang Pu*. Its original name is Zhang Ju, also known as Xi Fan Kui or Ying Yang Kui, and it is said to have abortifacient properties. However, using its abortifacient power to induce labor is indeed effective, which is why its petals are used as a guiding drug in Da Shun Tang. Sunflowers have stems about one zhang long, thick as bamboo, leaves large..., flowers plate-sized, single-petaled yellow, with a honeycomb-like center. When the central seeds mature, the surrounding petals do not wither. People often roast and eat the seeds, knowing they are non-toxic and slippery. It was once used alone to treat stranguria (Lin syndrome) with great efficacy. Later, used with Brucea javanica seeds (40 peeled Brucinae Semen, pounded with one liang of sunflower seeds, decocted and taken orally), it effectively treated gonorrheal stranguria. However, its ability to treat malaria was unknown. Recently, reading *Shaoxing Yixue Baoxue*, Lu XX described Kui treating malaria; thus, Zhang Ju can indeed be listed as a medicinal herb. The buds of Zhang Ju have stronger labor-inducing power than the seeds. I have seen cases where using only Zhang Ju buds induced immediate delivery, yet few people know this. Regarding using Weizu Zi for labor induction, it should be divided into old and tender types. Tender Weizi Zi requires several liang, crushed and boiled for juice consumption. If using old seeds, use approximately one liang, stir-fry lightly until the shell cracks, then decoct and drink.
