少壮之妇，于生产之后，或闻嫌谇，遂致两乳胀满疼痛，乳汁不通，人以为阳明之火热也，谁知是肝气之郁结
乎！夫阳明属胃，乃多气多血之府也。乳汁之化，原属阳明，然阳明属土，壮妇产后，虽云亡血，而阳明之气，实
未尽衰，必得肝木之气以相通，始能化成乳汁，未可全责之阳明也。盖乳汁之化，全在气而不在血，今产后数日，
宜其有乳，而两乳胀满作痛，是欲化乳而不可得，非气郁而何？明明是羞愤成郁，土木相结，又安能化乳而成汁也。

妇女产后完全没有乳汁，人们以为是乳管闭塞，哪里知道这是气和血都枯竭了呢！乳汁是由气血转化而成的，没有血液固然不能生成乳汁，没有气也不能生成乳汁。然而在这两者之中，血转化为乳汁的速度，不如气所转化的那样迅速。刚分娩的妇女，血液已经大量亏损，血液自身尚且顾不过来，又怎么能用来化生乳汁呢？乳汁完全依赖气的力量，来推动血液并转化它。现在产后几天，却一滴乳汁也下不来，这说明血少气衰是显而易见的。气旺盛则乳汁旺盛，气衰弱则乳汁减少，气枯竭则乳汁也枯竭，这是必然的趋势。世人不知道大补气血的妙处，而一味地通利乳窍，哪里知道没有气则乳汁无法化生，没有血则乳汁无法生成。治疗方法应当兼顾补气以生血，那么乳汁自然就会下来，不必专门用利窍的方法来通乳。
方名：通乳丹。
人参（一两） 生黄芪（一两） 当归（二两，酒洗） 麦冬（五钱，去心） 木通（三分） 桔梗（三分） 七孔猪蹄（二个，去爪壳）
水煎服。服用两剂后乳汁就会像泉水涌出一样。这个方子专门通过补益气血来生成乳汁，正因为乳汁生于气血之中。产后气血枯竭而没有乳汁，这与因乳管闭塞而没有乳汁的情况不可相提并论。不采用通乳的方法却命名为“通乳丹”，也是因为服用后乳汁通畅才这样命名；如果现在不通利乳窍而乳汁自生，即使命名为“生乳丹”也可以。
歌诀：产后乳汁点滴全无，原因是气血两虚吗？
气血充足乳汁旺盛，气血衰弱乳汁必干枯。
生乳丹中有参、通草，当归、麦冬、苦桔梗。
使用两个七孔猪蹄，服用两剂乳汁如泉涌。
年轻力壮的妇女，在生产之后，或者听到嫌弃责骂的话，导致两侧乳房胀满疼痛，乳汁不通，人们以为是阳明经的火热所致，哪里知道这是肝气郁结呢！阳明经属于胃，是多气多血的脏腑。乳汁的化生，原本属于阳明经，然而阳明经属土，壮年妇女产后，虽然说是失血，但阳明经的气实际上并没有完全衰竭，必须得到肝木之气的相通配合，才能化生乳汁，不能完全归咎于阳明经。大概乳汁的化生，全在于气而不在血，现在产后几天，按理说应该有乳汁，但两侧乳房胀满作痛，是想化生乳汁却做不到，这不是气郁是什么呢？明明是羞愤导致气机郁结，土木之气相互纠结，又怎么能化生乳汁呢？治疗方法应当大力舒展肝木之气，那么阳明经的气血自然通畅，乳汁也就通了，不必专门去通利乳窍。方名：通肝生乳汤。

Women who have absolutely no milk secretion after childbirth are often thought to suffer from blocked mammary ducts, but little do they know that this is actually due to the exhaustion of both Qi and Blood. Milk is transformed from Qi and Blood; without Blood, milk certainly cannot be generated, and without Qi, milk also cannot be generated. However, among these two, the transformation of Blood into milk is not as rapid as the transformation by Qi. A woman who has just given birth has already suffered a significant loss of Blood. Since her Blood is insufficient even to sustain herself, how can it be used to transform into milk? Milk relies entirely on the power of Qi to move Blood and transform it. Now, if several days have passed since childbirth and not a drop of milk is produced, it is evident that there is a deficiency of Blood and a decline of Qi. When Qi is vigorous, milk is abundant; when Qi declines, milk decreases; when Qi is exhausted, milk is also exhausted. This is an inevitable trend. People in the world do not understand the wonder of greatly tonifying Qi and Blood, but instead blindly use methods to unblock the ducts. They do not realize that without Qi, milk cannot be transformed, and without Blood, milk cannot be generated. The treatment method should involve tonifying Qi to generate Blood, so that milk will naturally flow down. There is no need to use methods that promote urination or open orifices to force lactation.
Formula Name: Tongru Dan (Cinnamon Twig Decoction for Lactation).
Ren Shen (Ginseng Radix) (1 liang), Sheng Huang Qi (Astragali Radix) (1 liang), Dang Gui (Angelicae Sinensis Radix) (2 liang, washed with wine), Mai Dong (Ophiopogonis Tuber) (5 qian, heart removed), Mu Tong (Akebiae Caulis) (3 fen), Jie Geng (Platycodonis Radix) (3 fen), Seven-hole pig trotters (2 pieces, claws and shells removed).
Decoct in water and take orally. After two doses, milk will gush forth like a spring. This formula specifically tonifies Qi and Blood to generate milk, precisely because milk is born from Qi and Blood. Postpartum exhaustion of Qi and Blood leading to lack of milk cannot be compared to cases where milk is absent due to blocked ducts. Although the method does not directly unblock the ducts, it is named "Tongru Dan" (Unblocking Milk Decoction) because milk flows freely after taking it; today, since milk generates without forcing its passage, it could equally be named "Shengru Dan" (Generating Milk Decoction).
Song Verse: Postpartum milk drops are nonexistent, is the cause the dual deficiency of Qi and Blood?
When Qi and Blood are sufficient, milk is abundant; when weak, milk must dry up.
In Shengru Dan, there are Ginseng and Akebia, Angelica, Ophiopogon, and Platycodon.
Use two seven-hole pig trotters; after two doses, milk flows like a spring.
For young and robust women, after childbirth, if they hear words of disdain or scolding, it may lead to distension and pain in both breasts with blocked milk secretion. People assume this is due to Heat-Fire in the Yangming channel, but little do they know it is actually caused by the stagnation of Liver Qi! The Yangming channel belongs to the Stomach, which is a reservoir abundant in Qi and Blood. The transformation of milk originally belongs to the Yangming channel. However, since Yangming belongs to Earth, and although a robust woman loses blood after childbirth, the Qi of Yangming is not completely depleted. It requires the connecting influence of Wood (Liver) Qi to facilitate the transformation of milk; thus, one cannot solely blame Yangming. Generally speaking, the transformation of milk depends entirely on Qi rather than Blood. Now, several days postpartum, milk should theoretically be present, yet the breasts are distended and painful. This indicates an attempt to transform milk that fails—what else could this be but Qi stagnation? Clearly, shame and indignation have led to Qi stagnation, causing Earth and Wood to knot together. How can milk be transformed and become fluid under such conditions? The treatment method should be to greatly soothe and disperse the Qi of the Liver (Wood), so that the Qi and Blood of Yangming will naturally flow, and milk will also flow. There is no need to specifically target the unblocking of milk ducts. Formula Name: Tonggan Shengru Tang (Soothe Liver and Generate Milk Decoction).
Bai Shao (White Peony Root) (5 qian, stir-fried with vinegar), Dang Gui (Angelicae Sinensis Radix) (5 qian, washed with wine), Bai Zhu (Atractylodis Macrocephalae Rhizoma) (5 qian, stir-fried with soil), Shu Di Huang (Rehmanniae Radix Praeparata) (3 fen), Gan Cao (Licorice Root) (3 fen), Mai Dong (Ophiopogonis Tuber) (5 qian, heart removed), Tong Cao (Tetrapanacis Medulla) (1 qian), Chai Hu (Bupleuri Radix) (1 qian), Yuan Zhi (Polygalae Radix) (1 qian).
Decoct in water and take orally. Patency is achieved after one dose; no further doses are necessary.
Marginal Note: Mai Dong should be stir-fried with millet. Not only does this prevent it from chilling the Stomach, but the flavor of the grain also guides it directly into the Stomach, thereby accelerating the generation of milk more rapidly.
Song Verse: Young women's milk should be rich, but shame and anger cause blockage and congestion.
Liver Qi stagnation causes breast distension and pain; soothing and unblocking Liver Qi allows milk to flow naturally.
Tonggan Shengru Tang contains White Peony, Angelica, and Ophiopogon, followed by Atractylodes, Bupleurum, and Polygala.
Rehmannia, Tetrapanax pith, and raw Licorice; after ingestion, milk flows like water.
