Treats Yangming disease presenting with a floating pulse, fever, thirst with desire to drink water, and dysuria (Cheng Wuji states: A floating pulse and fever indicate heat in the Upper Jiao; thirst with desire to drink indicates heat in the Middle Jiao; dysuria indicates heat binding in the Lower Jiao with blocked fluid metabolism. *Zhunsheng* states: The character "floating" here is erroneous; it should be that the character "pulse" is missing the character "not" below it. In the *Ming Pian* of the *Shanghan Lun*, it is also used to treat Shaoyin disease with thirst and diarrhea, taking advantage of its ability to descend fire and promote water metabolism, thereby stopping diarrhea and relieving irritability and thirst. Is this a method of draining the Fu organ of Shaoyin to calm the Jing channel of Shaoyin? Moreover, changing "floating pulse" to "non-floating pulse" has no precedent in formula literature.)

Shaoyin disease with diarrhea for six or seven days, accompanied by cough, vomiting, thirst, irritability, and insomnia. (If diarrhea occurs without thirst, it is an interior cold syndrome; if there is thirst, yang pathogenic factors have entered the interior; irritability and insomnia indicate the presence of heat pathogens; cough, thirst, and vomiting indicate retained fluids; if there is thirst accompanied by diarrhea, it can be inferred that urination must be difficult, indicating that heat pathogens have entered the Bladder. It is appropriate to promote diuresis, so that heat descends and stool solidifies. It is also generally used to treat damp-heat jaundice with thirst and dark red urine.)

Zhu Ling (Polyporus), Fu Ling (Poria), Ze Xie (Alisma Rhizome), Hua Shi (Talcum), E Jiao (Donkey-hide Gelatin) (each 1 liang).

This prescription acts on the Foot-Taiyang and Foot-Yangming channels. When heat obstructs upward, flow downward is blocked; when flow downward is blocked, heat further obstructs upward. Furthermore, dampness stagnation generates heat, and steaming heat exacerbates dampness. (Xu Zhicai states: Because various herbs are overly drying, Donkey-hide Gelatin is added to preserve body fluids. Note: Xu Zhicai stated that dryness can remove dampness, such as Sang Bai Pi (Mori Cortex) and Chi Xiao Dou (Vigna angularis). Wang Haogu stated that Talcum is an extremely drying agent. Generally, they regarded diuretic herbs as drying, rather than heat-drying herbs. Therefore, Tao Hongjing wished to add Cold and Heat categories outside the Ten Categories; in my *Bencao Bei Yao*, I classified heat herbs as drying agents and diuretics as unblocking agents. Wu Ling San addresses excessive dampness, thus using Gui Zhi (Cinnamomi Ramulus) and Bai Zhu (Atractylodis Macrocephalae Rhizome); Zhu Ling Tang addresses excessive heat, thus using Hua Shi (Talcum)).
