妇人有少腹之间，自觉有紧迫之状，急而不舒，不能生育。此人人之所不识也，谁知是带脉之拘急乎！夫带脉
系于腰脐之间，宜弛而不宜急。今带脉之急者，由于腰脐之气不利也。而腰脐之气不利者，由于脾胃之气不足也。
脾胃气虚，则腰脐之气闭；腰脐之气闭，则带脉拘急，遂致牵动胞胎。精即直射于胞胎，胞胎亦暂能茹纳，而力难
负载，必不能免小产之虞。况人多不能节欲，安得保其不坠乎？此带脉之急，所以不能生子也。治法宜宽其带脉之
急，而带脉之急，不能遽宽也，宜利其腰脐之气。而腰脐之气，不能遽利也，必须大补其脾胃之气与血，而腰脐可
利，带脉可宽，自不难于孕育矣。
方用宽带汤。
白术（一两，土炒） 巴戟肉（五钱，酒浸） 补骨脂（一钱，盐水炒） 人参（三钱） 麦冬（三钱，去心） 杜
仲（三钱，炒黑） 大熟地（五钱，九蒸） 肉苁蓉（三钱，洗净） 白芍（三钱，酒炒） 当归（一钱，酒洗） 五
味（三分，炒） 建莲子（二十粒，不去心）
水煎服。四剂少腹无紧迫之状，服一月即受胎。此方之妙，脾胃两补，而又利其腰脐之气，自然带脉宽舒，可
以载物而胜任矣。或疑方中用五味、白芍之酸收，不增带脉之急，而反得带脉之宽，殊不可解。岂知带脉之急，由
于气血之虚。盖血虚，则缩而不伸；气虚，则挛而不达。用芍药之酸以平肝木，则肝不克脾。用五味之酸以生肾水，
则肾能益带，似相碍而实相济也，何疑之有？
眉批∶凡种子治法，不出带脉、胞胎二经，数言已泄造化之秘矣。
歌括∶少腹急迫不育雏，腰脐气闭带脉束。
脾胃气虚原致此，大补脾土功效殊。
宽带巴戟熟地术，麦参杜仲补骨脂。
苁蓉归芍莲五味，四剂少腹紧迫除。
妇女中有人自觉小腹部有紧迫不适的感觉，急迫而不舒展，导致无法受孕。这是人们普遍不了解的，谁能想到这是因为带脉拘挛紧急呢！带脉系结于腰部和脐部之间，应当松弛而不应当紧张。如今带脉之所以紧张，是因为腰部和脐部的经气运行不畅。而腰脐经气运行不畅的原因，在于脾胃之气不足。
脾胃气虚，就会导致腰脐部位的经气闭塞；腰脐经气闭塞，就会引起带脉拘挛紧急，进而牵动胞胎。即使精液直接射入胞胎，胞胎暂时也能容纳，但力量难以承载，必然难免有小产的危险。况且大多数人不能节制房事，怎么能保证胎儿不坠落呢？这就是带脉紧张所以不能生育的原因。治疗方法应当舒缓带脉的紧张，但带脉的紧张不能立刻舒缓，应当通畅腰脐的经气。而腰脐的经气不能立刻通畅，必须大补脾胃的气与血，这样腰脐才能通畅，带脉才能宽舒，自然就不难孕育了。
方剂使用宽带汤。
白术（一两，土炒） 巴戟天肉（五钱，酒浸） 补骨脂（一钱，盐水炒） 人参（三钱） 麦冬（三钱，去心） 杜仲（三钱，炒黑） 大熟地黄（五钱，九蒸） 肉苁蓉（三钱，洗净） 白芍（三钱，酒炒） 当归（一钱，酒洗） 五味子（三分，炒） 建莲子（二十粒，不去心）
水煎服。服用四剂后小腹部没有紧迫的感觉，服用一个月即可受孕。这个方子的妙处在于同时补益脾胃，又通畅腰脐的经气，自然使带脉宽舒，能够承载胎元并胜任养育之责。有人怀疑方中使用五味子、白芍的酸收之性，不会增加带脉的紧张，反而能使带脉宽舒，这实在令人不解。哪里知道带脉的紧张，是由于气血虚弱造成的。因为血虚，则筋脉收缩而不能伸展；气虚，则筋脉痉挛而不能通达。使用白芍的酸味来平抑肝木，则肝木不再克制脾土。使用五味子的酸味来滋生肾水，则肾水能滋养带脉，看似相互阻碍，实则相互济助，有什么可怀疑的呢？
眉批：凡是治疗种子（受孕）的方法，离不开带脉和胞胎这两条经脉，这几句话已经泄露了造化的奥秘了。
歌括：
小腹部急迫导致不育雏，腰脐气闭导致带脉束缚。
脾胃气虚原本导致此症，大补脾土功效显著。
宽带汤含巴戟天、熟地黄、白术，麦冬、人参、杜仲、补骨脂。
肉苁蓉、当归、白芍、莲子、五味子，四剂后小腹部紧迫消除。
Women may experience a sensation of tightness and urgency in the lower abdomen, feeling constrained and uncomfortable, which leads to infertility. This is something most people do not understand; who would suspect that it is due to the contraction and tension of the Dai Mai (Girdle Vessel)? The Dai Mai is connected between the waist and the umbilicus; it should be relaxed rather than tense. The current tension of the Dai Mai is caused by the obstruction of Qi flow in the waist and umbilical region. The obstruction of Qi in the waist and umbilical region, in turn, is due to insufficiency of Spleen and Stomach Qi.
When Spleen and Stomach Qi are deficient, Qi closure occurs in the waist and umbilical region; when Qi is closed there, the Dai Mai becomes contracted and tense, thereby pulling on the Bao Luo (Uterus). Even if semen is directly deposited into the uterus, the uterus may temporarily accommodate it, but it lacks the strength to sustain it, inevitably leading to the risk of miscarriage. Moreover, since many people fail to regulate their sexual desires, how can they ensure the fetus does not fall? This is why the tension of the Dai Mai prevents conception. The treatment method should aim to relax the tension of the Dai Mai. However, this tension cannot be relieved immediately; one must first promote the free flow of Qi in the waist and umbilical region. Since Qi flow there cannot be immediately unblocked, it is necessary to greatly tonify the Qi and Blood of the Spleen and Stomach. Once the waist and umbilical region is unblocked and the Dai Mai is relaxed, conception will naturally become easy.
The formula used is Kuan Dai Tang (Broaden the Girdle Decoction).
Bai Zhu (Atractylodis Macrocephalae Rhizoma, 1 liang, stir-fried with soil)
Ba Ji Rou (Morindae Officinalis Radix, 5 qian, soaked in wine)
Bu Gu Zhi (Psoraleae Fructus, 1 qian, stir-fried with salt water)
Ren Shen (Ginseng Radix et Rhizoma, 3 qian)
Mai Dong (Ophiopogonis Radix, 3 qian, heart removed)
Du Zhong (Eucommiae Cortex, 3 qian, stir-fried until black)
Shu Di Huang (Rehmanniae Radix Praeparata, 5 qian, steamed nine times)
Rou Cong Rong (Cistanches Herba, 3 qian, washed clean)
Bai Shao (Paeoniae Radix Alba, 3 qian, stir-fried with wine)
Dang Gui (Angelicae Sinensis Radix, 1 qian, washed with wine)
Wu Wei Zi (Schisandrae Chinensis Fructus, 3 fen, stir-fried)
Jian Lian Zi (Nelumbinis Semen, 20 grains, heart not removed)
Decoct with water and take orally. After four doses, the sensation of tightness in the lower abdomen disappears; after one month of taking the decoction, pregnancy is achieved. The brilliance of this formula lies in its dual tonification of the Spleen and Stomach, while simultaneously promoting Qi flow in the waist and umbilical region. Naturally, the Dai Mai becomes wide and comfortable, capable of bearing and sustaining the fetus. Some may doubt that the use of the sour and astringent properties of Wu Wei Zi and Bai Shao in the formula would not increase the tension of the Dai Mai, yet instead result in its relaxation, which seems incomprehensible. How could one know that the tension of the Dai Mai stems from Qi and Blood deficiency? When Blood is deficient, tendons contract and fail to extend; when Qi is deficient, tendons spasm and fail to reach. Using the sour flavor of Bai Shao to pacify Liver Wood ensures that Liver does not overact upon Spleen Earth. Using the sour flavor of Wu Wei Zi to generate Kidney Water ensures that Kidney nourishes the Dai Mai. Though seemingly obstructive, they actually assist each other; what is there to doubt?
Commentary: All methods for treating infertility revolve around the Dai Mai and the Bao Luo; these few words have revealed the secrets of creation.
Verse:
Lower abdominal urgency prevents conception,
Waist and umbilical Qi blockage binds the Dai Mai.
Spleen and Stomach Qi deficiency causes this condition,
Greatly tonifying Spleen Earth yields remarkable effects.
Kuan Dai contains Ba Ji, Shu Di, and Bai Zhu,
Along with Mai Dong, Ren Shen, Du Zhong, and Bu Gu Zhi.
Rou Cong Rong, Dang Gui, Bai Shao, Lotus Seeds, and Wu Wei Zi,
Four doses remove the lower abdominal urgency.
