Weng Kentang stated: Chest stuffiness caused by anger is due to the stagnation of Liver Qi (Liver Qi). Chest stuffiness accompanied by fatigue is due to the deficiency of Middle Qi (Middle Qi). Chest fullness with excessive phlegm is due to the deficiency of Spleen Qi (Spleen Qi) (from *Yixue Zhunsheng*).

Ancient texts state: Regarding chest stuffiness, the upper half of the body belongs to Yang, and the lower half belongs to Yin; the chest area is the domain where clear Yang distributes, not a blockage by tangible pathogenic factors. If abdominal fullness occurs, it involves tangible pathogens rather than mere pathogenic qi obstruction. However, Pi Qi (stuffiness syndrome) can also cause chest fullness; how to distinguish them? The answer is: Pi Qi arises when pathogenic factors are in the exterior, and purgatives such as Nuxiaoshi (Mirabilite), Dahuang (Rhubarb Root and Rhizome), Badou (Croton Seed), or Qianniuzi (Bunge Morning Glory Seed) are mistakenly used for downward purging, leading to chest distension. One must ask if the patient has undergone purgation. If yes, it is Pi Qi; if no purgation was performed but there is chest fullness, it is a Shaoyang syndrome (half-exterior, half-interior syndrome).

In patients with sores and ulcers, collapse and sinking of Yang Qi may occur due to the excessive use of draining agents, massive loss of pus and blood, following vomiting and diarrhea, or erroneous sexual intercourse during illness. Symptoms include fever and headache, dysuria (difficult and painful urination), or a slippery and rapid pulse with hematochezia (blood in stool); red eyes, restlessness, panting, spontaneous sweating, fever with shortness of breath, dizziness, and physical fatigue; thirst with desire to drink water, yet aversion to cold after drinking; aversion to cold, body heat, aversion to clothing, throwing hands and feet about, profuse sweating like water, opisthotonos (backward arching of the back), continuous muttering (Zhengsheng). These constitute false heat syndromes caused by rootless deficient fire. Alternatively, symptoms may include aversion to cold and headache, cough with regurgitation of air and vomiting, deafness and blurred vision, urinary incontinence or difficulty urinating, diarrhea with borborygmus (rumbling in the intestines), tenesmus and abdominal pain, retraction of the penis, intermittent cold sweat, swelling of gums and teeth, limb numbness, cold extremities with body pain, grinding teeth and biting lips, and stiffness of the tongue root. These constitute true cold syndromes caused by the collapse and sinking of Yang Qi. Regardless of the pulse diagnosis or the condition of the sore, if one or two of these symptoms are present, Shenfu Tang (Ginseng and Aconite Decoction) should be urgently administered to tonify the deficiency. Many patients recover. Generally, after the ulceration of a sore, overexertion leads to the depletion of Yuan Qi (Original Qi); nocturnal emission with essence loss, a slippery and rapid pulse with hematochezia, invasion by external pathogens, or the mistaken use of cold-natured herbs can lead to the collapse and sinking of Qi and Blood, resulting in these syndromes. Treatment with the aforementioned remedies has also led to recovery.

Mei stated: When treating back sores, if the flesh grows too quickly and tenderly, such that the skin cannot cover it, exposure to wind will result in the formation of stiff flesh (rigid granulation tissue). Quickly calcine Hanshuishi (Halloysitum Rubrum), grind it into a fine powder, and apply it to the sore. Then, cover it with a fine powder of Tonglv (Malachite). The flesh will not become stiff (from *Yixue Zhunsheng*).
