巢氏云∶疳湿之病，多因久利，脾胃虚弱，肠胃之间虫动侵蚀五脏，使人心烦
懊闷，其上蚀者，则口鼻齿龈生疮，其下蚀者，则肛门伤烂，皆难治。或因久利，
或因脏热嗜眠，或好食甘美之食，并令虫动，致生此病也。《圣惠》夫小儿嗜食甘
味多而动肠胃间诸虫，致令侵蚀脏腑，此犹是 也。凡食五味之物，皆入于胃，其
气随其腑脏之味而归之，脾与胃为表里，俱象土，其味甘，而甘味柔润于脾胃，脾
胃润则虫动，虫动则侵蚀成疳也，但虫因甘而动故名之为疳也。若虫蚀下部，则肛
门生疮烂开，急者数日便死，宜速疗之。夫小儿乳食不节，冷热相乖，伤于脏腑，
致疳气也。若脾胃虚弱，则哺乳不消，大肠虚寒，遂变泄痢，因其久痢不止，肠胃
俱虚，为水湿所乘，腹内虫动，侵蚀下部，故名疳痢湿 也。

Chao Yuanfang stated: The disease of Gan-dampness (Gan with dampness) is mostly caused by prolonged diarrhea, leading to the deficiency and weakness of the Spleen and Stomach. Parasites between the intestines and stomach move and erode the five Zang organs, causing mental restlessness, vexation, and oppression. If the erosion occurs upwards, sores will grow in the mouth, nose, and gums; if downwards, the anus will be damaged and rot. Both are difficult to treat. Some cases arise from prolonged diarrhea, some from internal heat causing lethargy, or a preference for sweet and delicious foods, all of which cause parasites to move and result in this disease. *Taiping Shenghui Fang* records that children who consume too many sweets tend to have various parasites in the intestines and stomach move, leading to the erosion of Zang-Fu organs. This still belongs to Gan disease. All foods of the five flavors enter the Stomach. Their Qi returns to the corresponding organs according to their flavors. The Spleen and Stomach are exterior-interior pairs, both symbolizing Earth, with a sweet flavor. Sweetness moistens the Spleen and Stomach; when the Spleen and Stomach are moist, parasites move. When parasites move, they erode and form Gan disease. Because parasites move due to sweetness, it is named Gan disease. If parasites erode the lower part, sores and rot develop in the anus. In acute cases, death may occur within a few days, so rapid treatment is necessary. Irregular breastfeeding and diet, imbalance of cold and heat, damage to Zang-Fu organs lead to Gan Qi. If the Spleen and Stomach are weak, milk cannot be digested, the Large Intestine becomes deficient and cold, resulting in diarrhea and dysentery. Due to persistent dysentery, both intestines and stomach become deficient, invaded by water-dampness. Parasites move inside the abdomen, eroding the lower part, hence named Gan-dysentery-dampness.
