论曰：凡是下痢不止，或者是时气病余邪未清，被水湿之邪所侵袭，客居于肠胃之中，导致九虫皆动。侵蚀腑脏。所以形成湿病，所谓“蛊”（指因虫积或湿热导致的严重病变），是因为虫在隐蔽处活动而难以察觉的缘故。说这些虫因为湿气而活动，所以名叫湿蛊。其症状表现为上部则腐蚀唇口，下部则腐蚀肛门；上唇生疮，这是虫蚀五脏的表现，令人心烦懊恼；下唇生疮，这是虫蚀下部的表现，令人肛门受伤溃烂。如果胃气虚弱且气机上逆，就会转变为呕吐呃逆，严重时腑脏受到损伤，上下牙龈都生疮，牙齿颜色黯黑。这就是其征候。如果下痢排出瘀血，则不可治愈。

Commentary states: Whenever dysentery persists without cessation, or is due to residual pathogens from seasonal epidemic diseases, it is invaded by water-dampness. This pathogen lodges in the intestines and stomach, causing the "Nine Worms" (parasitic worms) to become active. They erode the fu organs and zang organs. Thus, a dampness disease arises. The condition referred to as "Gu" (a severe pathological state caused by worm accumulation or damp-heat) gets its name because the worms move in hidden places and are difficult to detect. It is said that these worms become active due to dampness, hence the name Damp-Gu. The symptoms manifest as erosion of the lips and mouth superiorly, and erosion of the anus inferiorly; sores appear on the upper lip, indicating that worms are eroding the five zang organs, causing mental restlessness and vexation. Sores appear on the lower lip, indicating that worms are eroding the lower part, causing injury and ulceration of the anus. If the stomach qi is deficient and rebellious, it transforms into vomiting and hiccups. In severe cases, the fu organs are damaged, sores appear on both the upper and lower gums, and the teeth turn dark black. These are the signs. If bloody stool with clots is passed during dysentery, it is incurable.
