治脾胃湿寒，饮食减少，长作泄泻，完谷不化。
白术（四两） 干姜（二两） 鸡内金（二两） 熟枣肉（半斤）
上药四味，白术、鸡内金皆用生者，每味各自轧细焙熟（先轧细而后焙者，为其焙之易匀也）。再将干姜
轧细，共和枣肉，同捣如泥，作小饼。木炭火上炙干，空心时，当点心，细嚼咽之。曾为友人制此方，和药一
料，服之而愈者数人。后屡试此方，无不效验。
一妇人，年三十许，泄泻数月。用一切治泻诸药皆不效。其脉不凉，亦非完谷不化。遂单用白术、枣肉，
如法为饼，服之而愈。此证并不用鸡内金者，因鸡内金虽有助脾胃消食之力，而究与泻者不宜也。

胞妹××，年四十余岁，体素瘦弱，久患脾胃湿寒，胃脘时觉疼痛，饮食减少，常作泄泻，完谷不化。因照
益脾饼原方，为制一料，服之即愈。为善后计，又服一料，永久祓除病根。
治泄泻久不止，气血俱虚，身体羸弱，将成劳瘵之候。
于术（一两，炒） 生山药（一两） 龙眼肉（一两）
小便不利者加椒目（三钱，炒捣）
龙眼肉，味甘能补脾，气香能醒脾，诚为脾家要药。且心为脾母，龙眼肉色赤入心，又能补益心脏，俾母
旺自能荫子也。愚治心虚怔忡，恒俾单购龙眼肉斤许，饭甑蒸熟，徐徐服之，皆大有功效，是能补心之明征。
又大便下血者，多因脾虚不能统血，亦可单服龙眼肉而愈，是又补脾之明征也。
一妇人，年四十许。初因心中发热，气分不舒，医者投以清火理气之剂，遂泄泻不止。更延他医，投以温
补之剂，初服稍轻，久服，则泻仍不止。一日夜四五次，迁延半载，以为无药可治。后愚为诊视，脉虽濡弱，
而无弦数之象，知犹可治。但泻久身弱，虚汗淋漓，心中怔忡，饮食减少，踌躇久之，为拟此方，补脾兼补心
肾。数剂泻止，而汗则加多。遂于方中加龙骨、牡蛎（皆不用 ）各六钱，两剂汗止，又变为漫肿。盖从前泻
时，小便短少，泻止后，小便仍少，水气下无出路，故蒸为汗，汗止又为漫肿也。斯非分利小便，使水下有出
路不可。特其平素常觉腰际凉甚，利小便之药，凉者断不可用。遂用此方，加椒目三钱，连服十剂全愈。
治疗脾胃湿寒，饮食减少，长期腹泻，大便中含有未消化的食物。
白术（四两） 干姜（二两） 鸡内金（二两） 熟枣肉（半斤）
以上四味药，白术和鸡内金都要用生品，每味药分别碾碎后焙干（先碾碎再焙干，是因为这样焙得容易均匀）。再将干姜碾碎，与枣肉混合，一同捣成泥状，做成小饼。在木炭火上烤干，空腹时作为点心，细细咀嚼咽下。曾为朋友配制此方，服用一料，有好几人痊愈。后来多次试用此方，没有不有效的。
有一位妇女，三十岁左右，腹泻几个月。使用所有治疗腹泻的药物都不见效。她的脉象不凉，也不是完谷不化。于是单用白术、枣肉，按照方法做成饼，服用后痊愈。这个证候之所以不用鸡内金，是因为鸡内金虽然有助脾胃消化食物的作用，但终究不适合用于腹泻患者。

直隶青县张××来信说：
我的妹妹××，四十多岁，身体一向瘦弱，长期患有脾胃湿寒，胃脘部时常感到疼痛，饮食减少，经常腹泻，大便中含有未消化的食物。因为照益脾饼原方，为她配制了一料，服用后即痊愈。为了善后调理，又服用了一料，永久除去了病根。
治疗腹泻长久不止，气血都虚弱，身体消瘦衰弱，将要形成劳瘵（肺结核类消耗性疾病）的征候。
于术（一两，炒） 生山药（一两） 龙眼肉（一两）
小便不通利的加椒目（三钱，炒捣）
龙眼肉，味甘能补脾，气香能醒脾，确实是脾脏的重要药物。而且心是脾的母脏，龙眼肉色赤入心，又能补益心脏，使母脏旺盛自然能荫庇子脏。我治疗心虚怔忡（心悸），常常让病人单独购买龙眼肉一斤左右，在饭甑中蒸熟，慢慢服用，都有很大功效，这是能补心的明显证据。另外大便下血的，多因脾虚不能统摄血液，也可以单服龙眼肉而痊愈，这又是补脾的明显证据。
一位妇女，四十岁左右。起初因为心中发热，气分不畅，医生投以清火理气的药剂，于是腹泻不止。又请其他医生，投以温补的药剂，初服稍轻，久服，则腹泻仍然不止。一天一夜四五次，拖延半年，认为无药可治。后来我诊治，脉象虽濡弱，但没有弦数之象，知道还可以治疗。但是腹泻久了身体虚弱，虚汗淋漓，心中怔忡，饮食减少，犹豫很久，为此拟定此方，补脾兼补心肾。几剂药后腹泻停止，但汗出更多。于是在方中加入龙骨、牡蛎（都不用煅制的）各六钱，两剂药后汗止，又变成了全身浮肿。因为从前腹泻时，小便短少，腹泻停止后，小便仍然少，水气下面没有出路，所以蒸发为汗，汗止后又变成浮肿。这不是分利小便，使水有出路不可。特别她平时常觉得腰部很凉，利小便的药，凉性的绝对不能用。于是用此方，加椒目三钱，连服十剂完全痊愈。
Treats Spleen-Stomach Damp-Cold (Pi Wei Shi Han), reduced food intake, chronic diarrhea, and undigested food in stool.
Bai Zhu (Atractylodis Macrocephalae Rhizoma) [4 liang], Gan Jiang (Zingiberis Rhizoma Recens/Secundum contextum dried/fried, here likely Zingiberis Rhizoma) [2 liang], Ji Nei Jin (Galli Gigerii Endothelium Corneum) [2 liang], Shu Zao Rou (Jujubae Fructus Pulpa, cooked) [0.5 jin].
The above four herbs: Bai Zhu and Ji Nei Jin must be used raw. Each herb is separately ground into fine powder and then roasted (roasting after grinding ensures evenness). Then, Gan Jiang is ground into powder, mixed with Zao Rou, and pounded together into a paste to form small cakes. These are dried over charcoal fire. Taken on an empty stomach as a snack, chewed thoroughly and swallowed. I once prepared this formula for a friend; one course of medication resulted in recovery for several individuals. Subsequent trials of this formula have consistently proven effective.
A woman, approximately thirty years old, suffered from diarrhea for several months. All other anti-diarrheal medications were ineffective. Her pulse was not cold, nor did she present with undigested food in the stool. Therefore, only Bai Zhu and Zao Rou were used, prepared into cakes according to the method, which cured her. This condition did not require Ji Nei Jin because, although Ji Nei Jin aids digestion in the Spleen and Stomach, it is generally unsuitable for patients with diarrhea.
Appendix:
Letter from Zhang XX of Qing County, Zhili:
My younger sister, XX, over forty years old, has always been thin and weak. She has long suffered from Spleen-Stomach Damp-Cold, occasional pain in the epigastrium, reduced appetite, frequent diarrhea, and undigested food in the stool. Following the original prescription of Yi Pi Bing, I had one dose prepared for her, which cured her immediately. For follow-up care, she took another dose, permanently eliminating the root cause of the disease.
Treats chronic diarrhea that does not cease, accompanied by deficiency of both Qi and Blood, emaciation, and symptoms approaching Lao Zhai (consumptive disease/tuberculosis).
Yu Zhu (Atractylodis Macrocephalae Rhizoma, fried) [1 liang], Sheng Shan Yao (Dioscoreae Rhizoma, raw) [1 liang], Long Yan Rou (Longan Aril) [1 liang].
If urination is difficult, add Jiao Mu (Zanthoxyli Semen, fried and crushed) [3 qian].
Long Yan Rou is sweet in taste and tonifies the Spleen; its aromatic qi awakens the Spleen. It is indeed a key herb for the Spleen organ. Furthermore, the Heart is the Mother of the Spleen. Long Yan Rou enters the Heart due to its red color and can tonify the Heart, allowing the Mother organ to flourish and thereby nourish the Child organ. In my treatment of Xin Xu Zheng Chong (Heart Deficiency Palpitations), I often advise patients to purchase about one jin of Long Yan Rou, steam it in a rice steamer until cooked, and consume it slowly. This yields significant effects, providing clear evidence of its ability to tonify the Heart. Additionally, hematochezia (blood in stool) is often caused by Spleen Deficiency failing to control blood; it can also be cured by taking Long Yan Rou alone, which is further evidence of its Spleen-tonifying properties.
A woman, approximately forty years old. Initially, due to heat in the Heart and stagnation of Qi, physicians administered formulas to clear fire and regulate Qi, resulting in persistent diarrhea. Other physicians were consulted, who administered warming and tonifying formulas. Initially, symptoms slightly improved, but with prolonged use, diarrhea persisted. The patient had diarrhea four to five times a day for half a year, deemed untreatable. Later, I examined her. Although the pulse was Ru Ruo (soft and weak), there was no Xuan Shuo (wiry and rapid) aspect, indicating it was still treatable. However, due to prolonged diarrhea and physical weakness, she had profuse spontaneous sweating, palpitations, and reduced appetite. After much deliberation, I prescribed this formula to tonify the Spleen while simultaneously tonifying the Heart and Kidney. After a few doses, diarrhea ceased, but sweating increased. Consequently, I added Long Gu (Fossilia Ossis Mastodi et Fossilia Ossis Cruris) and Mu Li (Concha Ostreae) [6 qian each, uncalcined] to the formula. After two doses, sweating stopped, but generalized edema developed. Previously, during diarrhea, urine output was scanty; after diarrhea ceased, urine remained scanty. With no outlet for water-dampness below, it evaporated as sweat; when sweating stopped, it manifested as edema. This required promoting diuresis to provide an outlet for water. However, since she usually felt extreme cold at the waist, cooling diuretic herbs were strictly contraindicated. Thus, using this base formula, I added Jiao Mu [3 qian]. Ten consecutive doses resulted in complete recovery.
