Zuo Gui Yin (Left-Restoring Decoction) with Fu Ling (Poria) removed, and Sheng Di Huang (Rehmanniae Radix Preparata) and Dang Gui (Angelicae Sinensis Radix) added to nourish the Stomach Yin. If the condition is severe, a potent formula must be sought; San Cheng Qi Tang (Three Inheriting Qi Formulas: Da Cheng Qi Tang, Xiao Cheng Qi Tang, Tiao Wei Cheng Qi Tang) should be used to unblock accumulation, which serves as an excellent guideline.

Food entering the mouth but being regurgitated indicates Cold in the Stomach family; trusting Wu Zhu Yu Tang (Evodiae Fructus Decoction) for treatment is not difficult. Furthermore, in cases of Fire transformation in the Lower Jiao (deficiency fire arising from Kidney Yang deficiency), Li Zhong Tang (Regulate the Middle Decoction) with Hua Jiao (Zanthoxyli Pericarpium) and Fu Zi (Aconiti Lateralis Radix Preparata) added can enhance appetite and provide warming tonification.

For Wei Fan (Stomantic Regurgitation, named "Wei Fan" in *Jin Gui Yao Lue* referring to vomiting and reflux), Ban Xia Tang (Pinelliae Rhizoma Decoction) is recommended first, its efficacy far exceeding ordinary remedies. As long as the Yangming channel can receive and the Chong vessel can descend, there is no need to argue over whether the syndrome is Cold or Warm.

Regarding Ge Zheng (Dysphagia/Obstruction Syndrome), I primarily follow the *Nei Jing* statement "San Yang Jie" (Binding of the Three Yang channels), considering feces resembling sheep droppings as a sign of death. Examining the *Ling Shu · Xie Qi Zang Fu Bing Xing Pian* chapter, it states: "If the Kidney pulse is slightly slow, it indicates Dong (Cavity/Leakage); Dong means food is not digested and comes back out immediately after swallowing." These three sentences serve as a diagnostic method opposite to Ge Zheng. Luo Longji, following the *Nei Jing*, specifically established the disease name as "Dong". The annotation states: "The Kidney governs the two lower orifices." Since the Kidney pulse is slightly slow, Kidney Qi is deficient. Once Kidney Qi is deficient, it cannot secure the stool, so food and drink are not digested; upon swallowing, there is choking, followed by immediate vomiting. "Xuan" (soon/immediately) is synonymous with "Huan" (return). This condition is called "Dong," attributed to Wind pathogen. "Dong" should be written as "Sun" (Sunning/Diarrhea), meaning Wind Qi penetrates the Five Zang organs. *Shi Ji · Cang Gong Lie Zhuan* states: "Sun Feng (Wind of Sunning) causes food and drink to pass down the throat and come out without staying; the illness arises from filth." It also states: "The manifestation of Sun Feng is that food and drink are expelled shortly after swallowing; the illness arises from walking rapidly after a full meal." The annotation explains: "Hou" refers to defecating. Ma Yuantai annotated this as Dong Xie (Loose Stool), which is slightly inaccurate, especially given the subsequent mention of more severe cases. *Ren Zhai Zhi Zhi Fang* uses Bu Huan Jin Zheng Qi San (Metal-Unchanging Upright Qi Powder) administered with An Shen Wan (Kidney-Anchoring Pill), concluding treatment with Er Shen Wan (Two Spirit Pill).

Yao Tong Zheng (Lower Back Pain Syndrome). The *Nei Jing · Ci Yao Tong Pian* states: "Foot Taiyang pulse floating causes lower back pain," indicating external contraction, treated primarily with Wu Ji San (Five Accumulations Powder). *Su Wen · Mai Yao Jing Wei Lun* states: "The waist is the mansion of the Kidney; if turning and shaking are impossible, the Kidney is about to fail," indicating internal deficiency, treated with Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) or Gui Fu Ba Wei Wan (Cinnamon and Aconite Eight-Ingredient Pill) added with Niu Xi (Achyranthis Bidentatae Radix), Du Zhong (Eucommiae Cortex), Yin Yang Huo (Epimedii Folium), Lu Rong (Cervi Cornu Pantotrichum), and Gu Sui Bu (Psoraleae Fructus). Pain like stabbing indicates Si Xue (Dead Blood/Stasis); Cervi Cornu (Deer Antler) powder is taken, along with Rou Gui (Cinnamomi Cortex), Niu Xi, Ru Xiang (Olibanum), Mo Yao (Myrrha), Yuan Hu (Corydalis Rhizoma), Tao Ren (Persicae Semen), and Hong Hua (Carthami Flos) decocted in wine and taken with four qian. Pain that is heavy and fixed, feeling like carrying five thousand coins, indicates Dampness, suitable for Shen Zhuo Tang (Kidney-Dampness Resolving Decoction). Pain that wanders or fluctuates irregularly indicates Phlegm accumulation, suitable for Er Chen Tang (Two-Aged Decoction) added with Nan Xing (Arisaematis Rhizoma Preparatum) and Qi-moving herbs to allow Phlegm to move with Qi. Additionally, can Bai Zhu (Atractylodis Macrocephalae Rhizoma) benefit the waist? For Si Xue, when all other medicines for lower back pain fail, using approximately one liang of Bai Zhu, assisted by a few other herbs, yields miraculous results after one dose. *Tai Ping Sheng Hui Fang* treats Feng Leng (Wind-Cold), Han Bi (Cold Bi), and lower back pain using Chuan Cao Wu (Aconiti Kusnezoffii Radix) three pieces, raw ground into powder, mixed with a little salt water, spread on paper, and applied to the painful area until cured. Since the waist is the mansion of the Kidney, it is listed among Interior Syndromes.
