On the first day of cold damage (Shanghan), the Foot-Taiyang meridian is affected. The Taiyang meridian belongs to the Bladder, and as the head of the three Yang meridians, it is the first to be affected. Its collaterals connect to the waist and spine, and govern the space between muscles and skin; therefore, it can be cured by applying ointments or using moxibustion to induce sweating. If the five Zang organs are disharmonious, the six Fu organs are obstructed, and Ying (Nutrient) and Wei (Defensive) Qi fail to circulate, death may occur after three days under such conditions.
[Note: The original text contains apparent textual corruption ("He Man") before describing the Shaoyang pattern. Based on standard Shanghan Lun theory, this section describes the third day.] The meridian courses along the hypochondrium and ascends to the neck and ears. Thus, on the third day of illness, there is heat in the chest and hypochondrium accompanied by deafness. The meridians of the three Yang stages begin to transmit sequentially; since the pathogen has not yet entered the Zang organs, it can be resolved through diaphoresis (sweating).
On the fourth day of cold damage, the Foot-Taiyin meridian is affected. The Taiyin meridian belongs to the Spleen and is the head of the three Yin meridians. Therefore, after the completion of the three-day cycle affecting the Yang meridians, the transmission moves to the Yin, and the Taiyin meridian becomes affected. Its collaterals connect to the Spleen and govern the throat. Thus, on the fourth day, abdominal fullness and dryness of the throat occur. Since the disease location is in the chest and diaphragm, it can be cured by emesis (vomiting).
On the fifth day of cold damage, the Foot-Shaoyin meridian is affected. The Shaoyin meridian belongs to the Kidney. Its channel penetrates the Kidney, connects with the Lung system, and links to the root of the tongue. Thus, on the fifth day, there is heat in the mouth, dryness of the tongue, thirst, and a desire to drink water. Since the disease location is in the intestines, it can be cured by purgation (downward draining).
On the sixth day of cold damage, the Foot-Jueyin meridian is affected. The Jueyin meridian belongs to the Liver. Its vessel courses through the yin regions and connects to the Liver. Thus, on the sixth day, there is vexation, abdominal fullness, and retraction of the genitals. At this stage, both Yin and Yang meridians are affected, and toxic pathogens reside in the Stomach; it can be cured by purgation.
On the seventh day, the Taiyang disease begins to recede, and the headache improves slightly. Generally, on the seventh day of cold damage, the condition should show slight improvement because the transmission through the Yin and Yang meridians has reached its conclusion. If the condition worsens after the seventh day, it indicates a "re-transmission" (Zai Jing Bing), meaning the meridians have been affected again.
On the eighth day, the Yangming disease begins to recede, and body heat subsides slightly. If the condition persists beyond eight days, it may be due to repeated infection of the various Yin and Yang meridians, or because toxic pathogens remain incomplete after previous treatments such as sweating, vomiting, or purging; thus, the symptoms persist.
On the ninth day, the Shaoyang disease begins to recede, and deafness slightly improves, allowing for faint hearing. If the condition remains unresolved after nine days, it might be because one meridian was disturbed and transmission ceased, or because the transmission through the three Yang meridians was completed but failed to enter the Yin, causing stagnation for several days. Consequently, the disease lingers, and the clinical manifestations change over time.
On the tenth day, the Taiyin disease begins to recede; the abdomen and stomach return to normal, and appetite returns.
On the eleventh day, the Shaoyin disease begins to recede; thirst ceases, vexation and abdominal fullness disappear, and dryness of the tongue resolves.
On the twelfth day, the Jueyin disease is cured; retraction of the scrotum and lower abdominal distension subside, all toxic pathogens are eliminated, and the course of the disease concludes.
