更有内伤劳倦，与中气虚寒之人，脾不摄血而成血痢，当用理中汤加木香、肉桂；或用补中益利汤加熟地、
炒黑干姜，治之而始愈也。
经验久泻血痢，小腹作痛，神效方∶
秋梨（四两） 生姜（五钱） 趋树根皮（一两）
共捣烂，夏布拧汁水，空心服之，立愈。
夏日中暑，红白痢疾，方用∶
焦山楂（五钱） 红糖（五钱） 白糖（五钱） 白萝卜（一个） 藿香（钱半）
水煎服。
若为白痢，用红糖一两，若为红痢，用白糖一两。〔若为红白痢，即用上方〕。
〔大便秘结者〕，人以为大肠燥甚也，谁知是肺气燥乎？盖肺燥则清肃之气，不能下行于大肠，而肾经之
水，仅足以自顾，又何能旁流以润涸哉？方用∶
熟地（三两） 元参（三两） 升麻（三钱） 牛乳（一碗） 火麻仁（一钱）
水二碗，煎六分，将牛乳同调服之，一、二剂必大便通矣。〔此方之妙，全不在润大肠而补肾，尤妙不止补
肾，而且补肺；更妙不正补肺，而且升肺。〕盖大肠居于下流，最难独治，必须从肾〔经〕以润之，从肺〔经〕
以清之，启其下窍，则上窍自然流动通利矣。此下病上治之法也。
〔大便不通，亦多实症，上方乃治虚症之方耳。此方治实症，实有奇效。方用〕∶
大黄（五钱） 归尾（一两） 升麻（五分） 蜜（半杯）
水煎服。
此方大黄泄利，当归以润之，仍以为君，虽泄而不至十分猛烈，不致有亡阴之弊。况有升麻以提之，则泄中有
留，又何必过虑哉？
更有因内伤劳倦，以及中气虚寒之人，脾脏不能统摄血液而形成的血痢，应当使用理中汤加入木香、肉桂；或者使用补中益气汤加入熟地黄、炒黑的干姜来治疗，这样才能痊愈。
经验治疗久泻导致的血痢，小腹疼痛的神效方：
秋梨（四两） 生姜（五钱） 趋树根皮（一两）
共同捣烂，用夏布拧出汁液和水，空腹服用，立刻痊愈。
夏日中暑，出现红白痢疾，方剂如下：
焦山楂（五钱） 红糖（五钱） 白糖（五钱） 白萝卜（一个） 藿香（一钱半）
用水煎服。
如果是白痢，使用红糖一两；如果是红痢，使用白糖一两。〔如果是红白痢，就使用上面的方子〕。
〔大便秘结的人〕，人们认为是大肠过于干燥，谁知道其实是肺气干燥呢？因为肺燥导致清肃之气，不能下行到大肠，而肾经的水液，仅足以顾护自身，又怎么能旁流去滋润干枯的大肠呢？方剂如下：
熟地黄（三两） 玄参（三两） 升麻（三钱） 牛乳（一碗） 火麻仁（一钱）
水两碗，煎至六分，将牛乳一同调和服用，一、二剂后大便必然通畅。〔这个方子的妙处，全不在于润大肠而在于补肾，尤其妙处不止于补肾，而且在于补肺；更妙处不在于直接补肺，而在于提升肺气。〕因为大肠位于下流，最难单独治疗，必须从肾经来滋润它，从肺经来清肃它，开启下面的窍道，那么上面的窍道自然流动通利了。这是下病上治的方法。
〔大便不通，也有很多是实证，上面的方子是治疗虚证的方子罢了。这个方子治疗实证，确实有奇效。方剂如下〕：
大黄（五钱） 当归尾（一两） 升麻（五分） 蜂蜜（半杯）
用水煎服。
这个方子中大黄泄利，当归用来润燥，仍然作为主药，虽然泄下但不至于十分猛烈，不会造成亡阴的弊端。况且有升麻来提升它，那么在泄下中有留存，又何必过分担忧呢？
Furthermore, for those suffering from internal injury due to overwork and fatigue, or with deficiency-cold of the Middle Qi (Middle Jiao Qi), where the Spleen fails to control blood resulting in bloody dysentery, Lizhong Tang (Regulate the Middle Decoction) should be used with added Muxiang (Aucklandiae Radix) and Rougui (Cinnamon Bark); or Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with added Shudi (Prepared Rehmanniae Radix) and Chaohei Ganjiang (Stir-fried Blackened Zingiberis Rhizoma) should be employed for treatment until recovery is achieved.
An effective empirical formula for chronic diarrhea leading to bloody dysentery accompanied by lower abdominal pain:
Qiu Li (Autumn Pear, 4 liang)
Sheng Jiang (Fresh Ginger, 5 qian)
Qu Shu Gen Pi (Bark of Qu Tree Root, 1 liang)
Mash them together thoroughly, squeeze out the juice using summer cloth mixed with water, and take on an empty stomach for immediate cure.
For heatstroke in summer presenting with red and white dysentery, use the following prescription:
Jiao Shan Zha (Charred Crataegi Fructus, 5 qian)
Hong Tang (Brown Sugar, 5 qian)
Bai Tang (White Sugar, 5 qian)
Bai Luo Bo (White Radish, 1 piece)
Huo Xiang (Pogostemonis Herba, 1.5 qian)
Decoct in water and take orally.
If it is white dysentery, use 1 liang of brown sugar; if it is red dysentery, use 1 liang of white sugar. [If it is red and white dysentery, use the above formula].
[Regarding constipation], people assume it is due to extreme dryness of the Large Intestine, but who knows that it is actually dryness of the Lung Qi? When the Lungs are dry, their clear and descending qi cannot flow down to the Large Intestine, and the water of the Kidney Meridian is only sufficient to maintain itself, let alone flow sideways to moisten the arid intestines. The prescription is as follows:
Shu Di Huang (Prepared Rehmanniae Radix, 3 liang)
Yuan Shen (Scrophulariae Radix, 3 liang)
Sheng Ma (Cimicifugae Rhizoma, 3 qian)
Niu Nai (Cow's Milk, 1 bowl)
Huo Ma Ren (Cannabis Semen, 1 qian)
Decoct in 2 bowls of water until reduced to 0.6 parts, mix with cow's milk, and take orally. After one or two doses, bowel movement will surely become unobstructed. [The brilliance of this formula lies not merely in moistening the Large Intestine but in tonifying the Kidney; its further brilliance lies not only in tonifying the Kidney but also in nourishing the Lung; and its greatest brilliance lies not in directly tonifying the Lung but in lifting Lung Qi.] Since the Large Intestine resides in the lower pathway and is difficult to treat independently, it must be moistened via the Kidney Meridian and cleared via the Lung Meridian. By opening the lower orifices, the upper orifices will naturally flow freely. This is the method of treating lower diseases from the upper aspect.
[Constipation often involves excess patterns; the aforementioned formula treats deficiency patterns. This formula treats excess patterns with remarkable efficacy. The prescription is]:
Da Huang (Rhei Radix et Rhizoma, 5 qian)
Gui Wei (Tanacetum Parietarium Radix et Rhizoma / Angelicae Sinensis Cauda, 1 liang)
Sheng Ma (Cimicifugae Rhizoma, 5 fen)
Mi (Honey, half cup)
Decoct in water and take orally.
In this formula, Da Huang promotes purgation, while Gui Wei moistens; Gui Wei remains the sovereign herb. Although it induces purgation, it is not overly harsh, avoiding the risk of Yin exhaustion. Moreover, with Sheng Ma to lift the qi, there is retention within the purgation, so why worry excessively?
