Wind pathogen transmits into the Shaoyin (Lesser Yin) channel. The pulse still presents as Yang floating and Yin weak, indicating that the pathological condition is vigorous; it must reach a state where the Yang pulse becomes faint and the Yin pulse becomes floating for the disease to be on the verge of resolution. This is because when Yang is faint, external pathogens no longer penetrate inward; when Yin floats, internal pathogens completely exit from the exterior. Thus, recovery is indicated.

When the Shaoyin pulse (Chi position) is weaker than the Fuyang pulse (dorsalis pedis artery), it is considered a favorable sign (Shun).

Shaoyin corresponds to Water, while Fuyang corresponds to Earth. In most diseases, one fears Earth overcoming Water; however, in the manifestations of Shaoyin cold damage, one specifically fears that Spleen Earth cannot control Kidney Water. If Kidney Water overflows instead, it leads to vomiting and diarrhea without limit, eventually causing the collapse of the Middle Jiao Earth Qi and the outward floating of True Yang, rendering even miraculous medicines ineffective. This is the subtle implication in pulse diagnosis and the profound essence of the disease's progression.

The above discusses the syndromes of returning Yang in Shaoyin disease.

Shaoyin disease tends to resolve during the hours from Zi (23:00–01:00) to Yin (05:00–07:00).

Each meridian resolves during its time of peak prosperity, but Shaoyin alone resolves during the time when Yang begins to generate. As Yang advances, Yin retreats; as Yang grows, Yin diminishes. This is precisely what is meant by "Yin resolves when it obtains Yang." By this reasoning, the emphasis in Shaoyin disease lies in True Yang, is it not evident?

The above clause describes the signs of spontaneous resolution of the Shaoyin channel.

This indicates a death prognosis. The human body's Yin and Yang rely on each other for attachment. When Yin perishes below and all Yang gathers at the head, moving chaotically, dizziness and frequent syncope occur. When Yang escapes upwards, death ensues. It can be seen that if Yang returns and diarrhea stops, life is preserved; if Yin is exhausted and diarrhea stops, death occurs.

In Shaoyin disease, if after six or seven days the breathing is shallow and high, death is indicated.

All Yang governs Qi. Shallow, high breathing indicates that True Yang rebels upward into the chest, the root is shaken first, and it cannot return to the Qi Sea (Lower Dantian), thus indicating death. The phrase "six or seven days" allows for the finest differentiation. Shaoyin disease with panting and high breathing persisting for six or seven days implies that True Qi has almost entirely escaped upward; why would it not die? This is distinctly different from the exterior syndrome of panting occurring two or three days into Taiyang (Greater Yang) disease. Furthermore, when Shaoyin Kidney Qi ascends to affect the Lungs, the pulse must be faint, minute, and powerless. If panting is caused by Taiyang pathogenic qi obstructing the Lungs, the pulse must be floating, tight, and forceful. They are naturally incomparable.

In Shaoyin disease with diarrhea, a faint and choppy pulse, vomiting, and sweating, accompanied by frequent defecation attempts but scant output, one should apply moxibustion to the upper part.

Diarrhea with a faint Yang and choppy Yin pulse indicates injury to both True Yin and True Yang. Vomiting indicates rebellious Yin pathogen; sweating indicates Yang deficiency failing to secure the exterior and Yin weakness failing to guard the interior. Frequent defecation attempts with scant output occur because Yang deficiency causes Qi to sink downward, and Yin weakness causes straining. Although this syndrome involves Yang deficiency requiring warming, Yin weakness makes pure warming unsuitable. Within a single prescription, simultaneously saving Yang and protecting Yin is difficult to distinguish. Therefore, moxibustion is applied to the Baihui (GV20) acupoint on the vertex to warm the upper region and raise Yang. This prevents Yang from stagnating below and forcing Yin; subsequently, Yin remains tranquil and undisturbed, and diarrhea ceases naturally. If medicinal warming were applied to the lower region, it would likely force Yin further, worsening diarrhea until Yin perishes instantly. Hence, warming medicines are avoided, and only moxibustion is used, achieving such a result in restoring Yang.
