These three conditions all represent severe deficiency syndromes. They arise from the dispersion of spirit and essence, leading to an inability to govern the body autonomously. Treatment should involve administering large doses of Dushen Tang (Ginseng Decoction) or Zuogui Yin (Left Restoring Decoction). There are cases where patients survive due to this treatment. (Referencing *Xitang Gan Zheng*)
Shao's Commentary: The symptoms of grasping at clothes (xun yi), touching the bed (mo chuang), and picking at empty air (cuo kong) often occur sequentially. They result from yin deficiency with excessive heat, causing the depletion of the primordial spirit (yuan shen) and loss of autonomous control, presenting as a false excess pattern arising from extreme deficiency. Dushen Tang is used to tonify the primordial spirit, while Zuogui Yin is used to strengthen kidney water to rescue the condition.
When yangming heat reaches its extreme and is left untreated, it leads to grasping at clothes and touching the bed, accompanied by slight panting and fixed staring. If the pulse is wiry (xian), survival is possible; if the pulse is choppy (se), death is certain. This belongs to the "bad disease" (huai bing) of Yangming. A wiry pulse indicates that the qi extends long and superabundant, suggesting that stomach qi remains, so purgatives like Chengqi Tang may be used. However, the condition is extremely critical. It must be understood that those showing signs of life may not necessarily survive, whereas those with a choppy pulse will certainly die, regardless of whether purgation is administered or not. (Referencing *Shu Gu*)
Shao's Commentary: In extreme Yangming heat, pathogenic factors are solid in the middle jiao, and yin qi is nearly exhausted, manifesting as grasping at clothes, touching the bed, slight panting, and fixed staring, with the primordial spirit depleted and uncontrolled. Therefore, pulse diagnosis is essential. If a wiry image is seen, it indicates remaining stomach qi; Chengqi Tang should be used to purge the excess heat to preserve a thread of yin qi, hoping for a chance of survival. If the pulse is choppy, it indicates exhaustion of yin and depletion of blood, making death inevitable.
In Taiyang disease, improper use of fire therapy to induce sweating causes excessive yang heat to injure yin, leading to grasping at clothes and touching the bed. If yin has not yet been exhausted, urination will be free, indicating potential survival; if yin has already been exhausted, urination will be difficult or absent, usually resulting in death. (Referencing *Yi Zong Jin Jian*)
Shao's Commentary: Fire therapy injures yin, causing extreme yang heat. The spirit is forced away by the fire and loses its residence, leading to grasping at clothes and touching the bed. The presence or absence of free urination is used to verify the existence or exhaustion of yin qi. If yin exists, there is life; if yin is exhausted, there is death.
In typhoid diseases, some patients present with constipation and anorexia. It is necessary to nourish stomach yin. When stomach yin is sufficiently replenished, pathogens will naturally be expelled, bowel movements will become smooth, and appetite will return. If nourishment is insufficient, pathogens will not immediately dissipate, and lack of appetite is acceptable.
Shao's Commentary: Constipation and anorexia indicate deficient stomach fluids with pathogenic stagnation. Yin deficiency causes constipation; pathogenic stagnation in the stomach causes anorexia. Treatment requires nourishing stomach yin. Once yin fluids recover, pathogens will recede naturally.
In typhoid diseases, some patients present with constipation but retain the ability to eat. This reflects the process of eliminating the old and generating the new, with the spleen and stomach functions benefiting, allowing for natural patency. There is no need to worry about constipation. (These two items are from *Xitang Gan Zheng*)
Shao's Commentary: Constipation with preserved appetite indicates yin deficiency without pathogenic stagnation in the stomach. Fluid deficiency causes constipation; the absence of pathogenic factors in the stomach allows for eating. The treatment consists solely of nourishing yin and fluids. Once yin fluids are sufficient, bowel movements will naturally become smooth.
