Wind-stroke of Jueyin. A pulse that is slightly floating indicates impending recovery; if not floating, the disease has not yet resolved.
This refers to a syndrome where the Jueyin meridian directly contracts wind pathogenic factors. A slight pulse indicates that the pathogenic factor is diminishing, while a floating pulse indicates that the disease is located in the meridians. Since the disease is in the meridians and the pathogen is weak, it indicates impending recovery. Alternatively, if the pulse was initially neither slight nor floating but later transforms into a floating pulse, this is a sign of transformation from Yin to Yang, also indicating impending recovery. This is what is meant by "those with Yin diseases obtaining Yang pulses will survive." However, this must be accompanied by symptoms such as mild fever and slight sweating. Zhang Zhongjing did not explicitly state these because the pulse encompasses the symptoms. If the pulse is not floating, the pathogen remains lodged within the Yin aspect without an outlet, making recovery uncertain; thus, it is said that a non-floating pulse indicates the disease has not resolved.

In cold damage, diarrhea occurring more than ten times a day, with a pulse that is surprisingly solid/excess (Shi), indicates death.
In cold damage with diarrhea reaching over ten times a day, the pathogens are not yet exhausted, but the healthy Qi is already severely depleted. The pulse should be thready or weak; if it is surprisingly solid/excess, it indicates excess pathogenic factors, known as "the disease overcoming the Zang organs." Therefore, it leads to death.

In diarrhea, a deep and wiry pulse indicates heaviness in the lower rectum (tenesmus); a large pulse indicates the condition has not stopped; a faint and rapid pulse indicates that the diarrhea is about to stop spontaneously. Even if there is fever, it will not be fatal.
A deep pulse indicates interior and downward conditions; a wiry pulse belongs to Yin. In diarrhea, a deep and wiry pulse indicates Yin pathogens in the interior and flourishing in the lower part, hence the sensation of heaviness in the lower rectum. A large pulse indicates flourishing pathogens; as the Classic states, "Large indicates disease progression," so the condition has not stopped. A faint pulse indicates weak pathogens; a rapid pulse indicates the return of Yang Qi. For Yin-cold diarrhea, the return of Yang Qi and weakening of pathogens indicate impending recovery. Even if fever occurs, it is caused by the internal sufficiency of Yang Qi and cannot be compared to the rule that diarrhea with fever indicates death.

In diarrhea, with slight fever and thirst, and a weak pulse, spontaneous recovery is expected. In diarrhea, with a rapid pulse, slight fever, and sweating, spontaneous recovery is expected. If the pulse becomes tight again, the disease is not resolved.
These two clauses are designed for cases of Yin pathogens sinking downward. Slight fever with thirst, and rapid pulse with slight fever and sweating, are all signs of internal sufficiency of Yang Qi, while a weak pulse is a sign of declining Yin Qi; thus, spontaneous recovery occurs. By "weak pulse," it means the pulse changes from tight to weak. If it becomes tight again, it means Yin pathogens remain strong, so how can the disease suddenly resolve?

In diarrhea, if the pulse is rapid and there is thirst, spontaneous recovery is expected. If it does not improve, pus and blood will inevitably appear in the stool, due to the presence of heat.
This is also a case of Yin-pathogen diarrhea where Yang Qi has already recovered. A rapid pulse with thirst is consistent with "diarrhea with slight fever and thirst." However, since the pulse is not weak but rapid, the recovery of Yang has exceeded the normal limit. Although Yin-cold is resolved, heat rapidly increases, which will further injure Yin and cause pus and blood in the stool.

Fever and cold extremities for seven days, accompanied by diarrhea, is difficult to treat.
Fever with cold extremities means the body is hot while the hands and feet are cold; the disease belongs to Yang, but the interior is deficient. By the seventh day, healthy Qi gradually recovers and pathogens retreat, so cold extremities should resolve first, followed by the disappearance of fever. Now, if cold extremities and fever remain unchanged, and diarrhea is added, it indicates that healthy Qi fails to recover and interior deficiency worsens. If the disease is not Yin-cold, one cannot use pungent-sweet-warm herbs to warm the interior; yet, due to internal insufficiency, one cannot use bitter-cold herbs to firm the lower jiao. This is why it is difficult to treat.

In cold damage, with fever, diarrhea, cold extremities, restlessness, and inability to lie down, indicates death.
In cold damage, with fever, diarrhea, and cold extremities, pathogens move from exterior to interior and flourish inside. When progressing to restlessness and inability to lie down, it indicates an imminent collapse of Yang Qi; therefore, it is fatal. This is transmitted-meridian pathogen, where Yin Qi exhausts first, followed by the cessation of Yang Qi.

In cold damage, with fever, severe diarrhea, and unceasing cold extremities, indicates death.
Fever, severe diarrhea, and cold extremities present similarly to the previous clause. However, severe diarrhea indicates impending exhaustion of Yin; unceasing cold extremities indicate injury to Yang. Even without restlessness, it is still fatal. This is also a transmitted-meridian pathogen, where Yin exhausts first and Yang follows.

In cold damage, on the sixth or seventh day, when there was previously no diarrhea, sudden onset of fever and diarrhea, with incessant sweating in the patient, indicates death, due to having Yin but no Yang.
Cold injuring the Yin aspect, fever appearing on the sixth or seventh day usually indicates Yang recovery and Yin resolution; even with diarrhea, it should stop spontaneously. This is what is meant by "in cold damage, if there is initial cold extremities followed by fever and diarrhea, the diarrhea must stop." However, in cold damage on the sixth or seventh day, if there was originally no diarrhea but sudden fever and diarrhea appear together, this is not Yang-recovery heat, but rather Yin flourishing internally and Yang perishing externally. If the patient has incessant sweating, not only can Qi not guard internally, but there is also no protection externally. This is called "having Yin but no Yang," and death is certain.

In diarrhea, with cold extremities and absent pulse, if moxibustion does not warm the limbs, and if the pulse does not return but instead slight panting occurs, indicates death.
Yin-cold diarrhea progressing to cold extremities and absent pulse indicates that Yang Qi is about to exhaust, leading to death. Moxibustion is used to restore severed Yang Qi. If cold extremities do not reverse, the pulse does not return, and slight panting occurs, it indicates residual Yang rushing upward and vital Qi collapsing downward; therefore, it is fatal.

After diarrhea, if the pulse is absent and extremities are cold, but the pulse returns at intervals and extremities become warm, survival is possible; if the pulse does not return, death ensues.
"Interval" refers to a full cycle (e.g., twelve double-hours). After diarrhea, absent pulse and cold extremities indicate Yin exhaustion preceding Yang cessation. One should wait for a cycle for the meridian Qi to circulate once; then the pulse should return and extremities should warm. If the pulse does not return and extremities remain cold, death will occur.

In cold damage, on the sixth or seventh day, with a faint pulse, cold extremities, and irritability, moxibustion applied to the Jueyin meridian; if cold extremities do not resolve, indicates death.
On the sixth or seventh day of cold damage, it is the time when Yang Qi should recover and Yin pathogens should resolve. Yet, the pulse is faint rather than floating, and extremities are cold rather than merely irritable; this indicates Yin advancing while Yang retreats. Irritability signifies Yang struggling against Yin but failing to overcome it. Moxibustion on the Jueyin meridian aims to disperse Yin pathogens and restore Yang Qi. If Yang recovers, cold extremities will naturally resolve. If they do not resolve, it indicates Yang cessation and death. Thus, for transmitted-meridian pathogens reaching Jueyin, death does not occur if Yin Qi is not exhausted; for direct invasion pathogens entering Jueyin, life is impossible if Yang Qi does not recover.

In cold damage, with a slow pulse persisting for six or seven days, if one erroneously administers Huangqin Decoction to clear heat: Slow pulse indicates cold. Administering Huangqin Decoction further removes heat. The abdomen should feel cold, and appetite should be lost. If the patient can eat contrary to expectation, this is named "Chu Zhong" (Elimination of the Middle), indicating certain death.
Rapid pulse indicates heat; slow pulse indicates cold; this is a fundamental principle of pulse diagnosis. Heat is cleared; cold is warmed; this is the primary method of treatment. However, in cold damage, if the slow pulse persists for six or seven days without change, it is undoubtedly cold. Erroneously administering Huangqin Decoction (Scutellaria Root Decoction) to clear heat exacerbates the cold. Consequently, Yang Qi perishes, and Yin-cold dominates. Physiologically, the abdomen should be cold and appetite absent. If the patient can eat, it is not due to robust Stomach Qi, but rather the exposure of Stomach Yang without reserve. It is like a poor person boasting of wealth, displaying everything they own; although dazzling momentarily, their emptiness is immediately apparent. Therefore, it is directly diagnosed as "Chu Zhong" (Elimination of the Middle), indicating certain death.

The time when Jueyin disease tends to resolve is from Yin hour to Mao hour.
Jueyin belongs to the Wind-Wood viscera. Yin and Mao hours are the times when Wood Qi is dominant. When the visceral Qi prevails, pathogens resolve. This follows the same pattern as the Three Yang meridians and the Taiyang-Shaoyin and Shaoyang-Taiyin pairs.
