This passage further discusses the Qi of the Yangming channel failing to distribute to the four extremities, resulting in Wei syndrome (flaccidity) and Jue syndrome (cold limbs). "Wei" refers to the weakness of the hands and feet such that they cannot be controlled by one's will. "Jue" refers to the coldness of the hands and feet. The Yangming channel governs the "He" (closing function); if Qi flow is obstructed leading to a fracture of the closing function (He Zhe), the Qi has no place to rest and becomes disordered, giving rise to flaccidity diseases. Yang Qi receives nourishment at the four extremities; when the Qi of the Yangming channel fails to circulate normally, it results in cold extremities.
The Yangming channel resides in the center and belongs to Earth, serving as the "Sea" of water and grain. Just as the ocean generates clouds and mist across the world, the previous text discussed how the Qi of the Yangming channel fails to ascend and descend between the upper and lower parts, while this section discusses its failure to distribute to the four directions. Zhu Yongnian stated: "Shu" means stuffiness. The phrase "binding the four extremities" implies binding the hands and feet to induce a sensation of fullness, then releasing them to treat the disease, thereby guiding the free flow of Qi. Pressing and binding are both methods of Daoyin (guiding and pulling exercises), similar to how the inchworm must first curl up before extending itself. The upper half of the body belongs to Yin-Yang (Yang), and the lower half belongs to Yin; the first half of the day belongs to Yang, and the second half belongs to Yin. "Ri Er" (two days/times) signifies enabling the Qi of Yin and Yang above and below to manifest and communicate with each other. "Bu Ren" (loss of sensation) refers to the stagnation of Ying Blood (Nutritive Blood). Ten days represent the completion of one cycle of the Yin number.
Stimulating the nose with grass to induce sneezing (Ti) cures the condition once the sneeze occurs. If nasal breathing is blocked, rapidly guiding and attracting the Qi will also stop the condition immediately. Being greatly startled can also cure it. (Note: The character "Sui" here should be read as "Yue", pronounced like "Ti").
"Yue" refers to hiccuping. It is named so because the sound produced resembles the ringing of carriage bells with a rhythmic order. This occurs because the Grain Qi received by the Yangming channel attempts to transfer from the Lung to the skin surface, but Lung Qi rebels and returns to the Stomach. The Qi merges and rebels together, exiting again from the Stomach, thus causing hiccups. Therefore, stimulating the nose to induce sneezing is used to unblock Lung Qi. Once Lung Qi is unblocked, Grain Qi can be transported smoothly, and the hiccups cease. "Wu Xi" refers to blocked nasal breathing; "Ji Ying Yin Zhi" refers to continuously inducing sneezes. When food enters the Stomach, its essence scatters to the Heart and Liver. Great fright causes the Qi of the Liver and Heart to scatter, allowing the rebellious Qi of the Stomach to dissipate outward. According to meridian theory, the collaterals of the Stomach connect upwards to the Heart, and the meridians of the Liver flank the Stomach. This indicates that the Qi of the Yangming channel can exit via Lung Qi into the Qi aspect, or via the Liver and Heart into the Blood aspect.
This chapter discusses the causes of miscellaneous diseases: some arise from Qi dysfunction, some involve Jue pathogens in the meridians, and some involve the simultaneous rebellion of meridian Qi. It begins with the Taiyang channel and concludes with the Yangming channel. This is likely because the Taiyang channel is the master Qi of all Yang channels, and the Yangming channel is the source of Qi and Blood generation, allowing Qi to circulate through the upper, lower, and surrounding areas. Whether in the Qi aspect or the Blood aspect, human diseases do not exceed external and internal causes. Both external and internal diseases can cause Qi and Blood to rebel and become stagnant. Therefore, most diseases originate from stagnation and rebellion. If students carefully study the causes and syndromes of Jue rebellion described in these sections, they will grasp the essentials of treatment and understand more than half of the subject matter. Zhang Jiabin stated that "Sui" should be written as "Yue".
