When Qi and Blood are harmonious, myriad diseases do not arise; once there is stagnation (Fuyu), various diseases emerge. Therefore, most diseases of the human body originate from stagnation. Cangzhu (Atractylodis Rhizoma) and Fuxiong (Chuanxiong Rhizoma) can generally resolve all types of stagnation, with additional herbs added according to the specific syndrome.

All stagnations occur in the Middle Jiao (Middle Burner). Cangzhu and Fuxiong are used to lift and raise the Qi. For instance, if food is stagnant in the upper aspect of the Qi level, lifting the Qi will cause the food to descend naturally. Additionally, Dai Yuanli stated: "Stagnation" refers to condensation that cannot be dispersed. What should ascend fails to ascend, what should descend fails to descend, and what should transform fails to transform, leading to dysfunction in transmission and transformation. Thus, the six types of stagnation syndromes appear. Qi stagnation manifests as pain in the chest and hypochondrium, with a deep and choppy pulse; Dampness stagnation manifests as wandering pain throughout the body or joint pain, which flares up upon exposure to cold, with a deep and fine pulse; Phlegm stagnation manifests as panting upon movement, with a deep and slippery pulse at the Cun Kou position; Heat stagnation manifests as dizziness and oppression, dark red urine, and a deep and rapid pulse; Blood stagnation manifests as weakness in the four limbs, normal appetite but blood in the stool, and a deep pulse; Food stagnation manifests as sour belching, abdominal fullness with inability to eat, a peaceful Ren Ying pulse, and a flourishing Qi Kou pulse.

Li Dongyuan's *Bian Zheng Lu* (Differentiation of Internal and External Injury) discusses this in great detail, and many people in the world suffer from this disease. However, some cases involve concurrent Phlegm, some involve concurrent Exterior pathogens, and some involve concurrent Heat stagnation. The primary treatment is to tonify Yuan Qi (Primal Qi), while adding herbs based on the concurrent pathogen. For cases with concurrent Phlegm, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Banxia (Pinelliae Rhizoma) and Zhuli (Bambusae Sap), along with a small amount of Jiangzhi (Ginger Juice) as a guiding vehicle. Whenever internal injury causes macules (ban), it is due to extreme deficiency of Stomach Qi, causing Fire to wander to the exterior; this is also caused by Phlegm-Heat. For Fire, use tonification combined with descending methods; for Phlegm-Heat, use mild sweating to disperse it. One must absolutely avoid purgatives, lest critical conditions arise. After the retreat of internal injury diseases, if dryness and thirst persist, it indicates residual Heat in the Lung. One may use Renshen (Ginseng Radix et Rhizoma), Fuling, Gancao (Glycyrrhizae Radix et Rhizoma), and a small amount of Ginger Juice, taken cold, or administered drop by drop with a tea spoon. For deficient constitutions, Renshen may be used.

[Appendix] The origin of internal injuries lies in excessive joy or anger, irregular diet, inappropriate temperature regulation, and overexertion. Yuan Qi is the Qi that generates and ascends among the Yang energies. When food enters the Stomach and causes damage, the Middle Qi becomes insufficient. Insufficient Middle Qi leads to the cessation of the Six Fu Organs' Qi externally, which is the fundamental pathology of the Six Fu Organs. When Qi is injured, the Zang organs become diseased; when Zang organs are diseased, the形体 (body/form) responds. This indicates that the True Qi of the Five Zang and Six Fu Organs is all insufficient. Only Yin Fire flourishes alone, ascending to the Yang regions, causing the Wei Qi (Defensive Qi) to lose its guard, and thus various diseases arise. Diseases initially caused by dietary and fatigue injuries must present with high-pitched breathing and panting, fever and irritability, shortness of breath with upward reversal, regular nasal breathing, lethargy and desire to lie down, heaviness and lassitude of the four limbs, lack of Qi to move, and lack of Qi to speak. These are all Heat injuring Yuan Qi. Using sweet-warm agents to tonify Qi is essentially a method of draining Fire. Upon palpation of any such disease, the skin and muscles will definitely feel very hot, accompanied by dry heat, oppression, restlessness, and irritability, or thirst. In long-standing diseases, there is usually no thirst. Or there may be superficial deficiency with aversion to wind and cold. One must strictly avoid giving cold-cooling medicines. The Classics state: "For exhaustion, use warmth; for deficiency, use warmth." Only use warm medicines like Buzhong Yiqi Tang to tonify Yuan Qi and drain Fire evil. The *Neijing* states: "Warmth can eliminate great heat," which precisely refers to this.
