When the seventh day arrives, the pathogenic factor has sufficiently transmitted to the Yin aspect. If there is slight body heat, a yellowish complexion, slightly warm hands and feet, and clear spirit, this indicates that Yang Qi is about to recover and Yin Qi is about to resolve. Even if sudden high fever and sweating occur, this is a sign that the pathogen returns to the exterior and is about to be resolved. If the fever persists with drowsiness and restlessness, this indicates that the pathogen overcomes the healthy Qi, Yin reaches its extreme transforming into heat, which is a fatal prognosis. If between the seventh and eighth days, there is lockjaw with inability to speak, restlessness, body heat, or shivering, this represents a struggle between Yin and Yang. If the pulses at the Cun, Guan, and Chi positions are all present and strong, and the eyes are yellow, this indicates that healthy Qi overcomes the pathogen, and the condition will heal.

If within one or two days of onset, the disease transmits to the Taiyang (Greater Yang) and Yangming (Yang Brightness) meridians, headache and fever should occur, along with restless sleep and a floating, large pulse. If instead the patient sleeps peacefully, has no thirst or irritability in the mouth, maintains a clear spirit, and presents with a deep, slow, and solid pulse without irregular breathing, although the exterior appears affected by cold, it is because Yin Qi is prosperous and resists the pathogen, so the exterior signs do not manifest in the pulse. This condition should resolve after the Three Yang diseases transmit through the Foot meridians, and it should not be discussed as "Yang disease presenting with Yin pulse." However, Yang diseases must heal by the seventh day, and Yin diseases by the sixth day, because Yang diseases follow the number of Fire (seven), and Yin diseases follow the number of Water (six).

A blue nose indicates abdominal pain. If caused by cold, it is fatal. A slightly black nose indicates water retention. A yellow nose indicates difficult urination. A white nose belongs to Qi deficiency. A red nose belongs to Lung Heat. A bright and lustrous nose indicates retained fluids (Liuyin). Dry nostrils indicate epistaxis. A dry nose resembling soot indicates extreme heat from Yang Toxin. Cold, slippery, and black nostrils indicate extreme cold from Yin Toxin. Thick nasal discharge belongs to Wind-Heat. Clear nasal discharge indicates Lung Cold. Distended nostrils indicate Lung Heat with Wind. Scorched red lips and mouth are auspicious. Scorched black lips and mouth are ominous. Swollen and red lips and mouth indicate extreme heat. Blue-black lips and mouth indicate extreme cold. Broken and twisted lips, mouth, and tongue are difficult to treat. Dry and cracked lips and mouth indicate Spleen Heat. Blue lips with curled tongue are fatal. Blue lips and mouth corners are fatal. Black around the mouth is fatal. Mouth open with straight outflow of breath is fatal. Dry teeth without saliva indicate extreme Yangming Heat. Dry front incisors with a deficient pulse indicate Summerheat. Teeth feeling hot are difficult to treat. Black and dry ears indicate Kidney exhaustion. Red eyes, scorched lips, and black tongue belong to Yang Toxin. Dark yellow inside the eyes belongs to Damp-Toxin. Yellow eyes with free urination, black stool, and lower abdominal fullness/pain belong to Blood Stasis. Closed eyes indicate impending epistaxis. Yellow sclera with no thirst and a deep, fine pulse belongs to Yin Jaundice. Yellow eyes indicate the disease is about to heal. Opening eyes to see people belongs to Yang. Closing eyes and unwillingness to see people belongs to Yin. Dim eyes unable to recognize people, eyes rolling upward, small staring pupils, fixed gaze, strabismus, round fixed eyeballs, eyes deviated upward with opisthotonos, and sunken eye sockets—these eight conditions are all fatal. Eyes slightly fixed but occasionally moving belong to Phlegm. Unclear vision and disordered eyes, unable to see clearly, result from pathogenic heat knotting internally. "Unclear" means seeing half and not seeing half. Black eye orbits also indicate internal Phlegm. Swollen tongue is treated with Xionghuang (Realgar). Tongue protruding and unable to retract is fatal. Red cheeks observed in the afternoon indicate rising Deficient Fire and should not be treated as Shanghan. Red face with rapid but weak pulse indicates Fu Yin Disease (Hidden Yin Disease), a false heat syndrome. Red face with deep and fine pulse indicates Shaoyin Disease, external heat and internal cold, with Yin excess repelling Yang; warming methods are appropriate. Misuse of cold/cooling herbs leads to death. Red face with wiry and rapid pulse indicates Shaoyang Disease; Xiaochaihu Tang is indicated for harmonizing. General redness of the face indicates unresolved Yangming exterior syndrome; muscle-releasing methods are indicated, not purgation. Blue face and lips indicate extreme Yin Cold. Blue face with curled tongue and retracted testicles also indicates Yin Cold. Blue face with severe lower abdominal colic indicates Jia Yin Shanghan (Cold Damage involving Yin). Yellow face, eyes, and body with scanty, obstructed urination indicate Damp-Heat. Yellow face, eyes, and body with lower abdominal fullness, hardness, pain, and free urination indicate Blood Stasis Shanghan. White face indicates lack of Spirit or blood loss due to excessive sweating; persons with white faces should not sweat excessively. Confusion and delirium after sweating, purging, or vomiting constitute Huai Bing (Ruined Disease). Fixed gaze, wheezing, fullness, and diarrhea are fatal. Deep pulse with cold limbs is fatal. Black qi in the corner of the eye extending to the Taiyang region is fatal. Black qi entering the mouth from the Renzhong point is fatal. Black qi entering the eyes, ears, nose, or tongue is fatal. In patients with a black face suffering from Shanghan involving deficiency, large tonics like Renshen (Ginseng) and Baizhu (Atractylodes Macrocephala) should not be used, as Qi is often Excess.
