Note: This section belongs to Mr. Dongyuan's "Differentiation of Internal and External Injuries". Its discussions and prescriptions are exquisite and complete, therefore other books are not selected. However, content not related to internal injury treatment is excerpted but not fully recorded. The discussion on Summerheat Syndrome is appended to the Summerheat Section.

Ancients distinguished between internal injuries and external infections by pulse, comparing the Renying (Human Welcome) pulse and the Qikou (Qi Mouth) pulse. If the Renying pulse is larger than the Qikou pulse, it is an external infection; if the Qikou pulse is larger than the Renying pulse, it is an internal injury. This differentiation is indeed correct, but its explanation is not exhaustive. External contraction of Wind-Cold all belong to excess syndromes, caused by pathogenic factors invading from outside. The disease manifestations must appear in the left hand, because the left hand governs the exterior and circulates Yang for twenty-five degrees. Internal injuries caused by diet, irregular eating habits, and overexertion all belong to deficiency syndromes. The disease manifestations must appear in the right hand, because the right hand governs the interior and circulates Yin for twenty-five degrees. Therefore, when contracting Cold Evil externally, only the left-hand Renying pulse appears floating and tight. Pressing it reveals a surging, large, and tight quality, urgent even exceeding the string-like quality. This is the pulse of the Foot-Taiyang Bladder channel (Water). Pressing it reveals a surging and forceful quality, internally manifesting the pulse of the Hand-Shaoyin Heart channel (Fire). Ding and Ren combine, internally manifesting a surging quality; this is the pulse of Cold Damage (Shanghan). If contracting Wind Evil externally, then the Renying pulse is slow and large, or one, two, or three times larger than the Qikou pulse. For internal injury due to diet, the right Cun position of the Qikou pulse is larger than the Renying pulse by one time. If the injury is severe, involving the Shaoyin channel, it is two times larger; involving the Taiyin channel, it is three times larger. This is the pulse of internal injury due to diet. If due to irregular diet or excessive exertion, the Heart pulse changes appear at the Qikou. This is Heart Fire punishing Lung Metal. Liver Wood, carrying the momentum of Heart Fire, also attacks the Lung Meridian. As stated in the classics: "Insulting what it cannot overcome, lacking fear," refers to this principle. Thus, the Qikou pulse is urgent, large, and rapid, occasionally showing a intermittent pulse (Dai Mai) and choppy quality (Se). Se (choppy) is the root pulse of the Lung. Large indicates Yuan Qi (Original Qi) failing to connect, and Spleen-Stomach insufficiency. Surging, large, and rapid indicates Heart Fire punishing Lung. Urgent indicates Liver Wood carrying Heart Fire counter-attacking Lung Metal. If exertion is not severe, only the right Guan position Spleen pulse appears large and rapid, specifically larger than the other five pulses. Within the rapid quality, it shows slowness, occasionally showing an intermittent pulse. If due to irregular diet or improper adaptation to cold and heat, first the right Guan Stomach pulse becomes damaged and weak; in severe cases, it hides and disappears, only internally manifesting the Spleen pulse as large, rapid, slightly slow, occasionally showing an intermittent pulse. Undigested food retention manifests solely as a deep and slippery pulse at the right Guan position. The classics state: "A slippery pulse indicates retained food."
