论述说：虫与人生于同一时期，潜伏在隐蔽之处。它们造成的危害，根本原因在于人体正气虚弱。如果既食用了生冷食物，又感受了风邪，就会导致虫体发生各种变化并大量繁殖。起初似乎不足为惧，但严重时足以致人死地。善于养生的人，会饮食清淡，节制欲望，早早去除体内的“三尸”（道教认为寄居人体内作祟的三种害虫），在疾病未发生前就加以防范。这样，那九种虫也会在不知不觉中消亡。如果不遵循此道，就必须通过药物祛除孽障、剔除蛀虫，防止其蔓延滋长，因为确实有药物可以治疗。
论述说：所谓“九虫”，第一种叫伏虫，长度四分；第二种叫蛔虫，长度一尺；第三种叫白虫，长度一寸；第四种叫肉虫，形状像腐烂的杏子；第五种叫肺虫，形状像蚕；第六种叫胃虫，形状像蛤蟆；第七种叫弱虫，形状像瓜瓣；第八种叫赤虫，形状像生肉；第九种叫蛲虫，形状像菜虫，极其微小细微。这九种虫都盘踞在肠胃之间。如果脏腑之气充实，它们就不能造成危害；一旦脏腑气虚，虫体就会发动变化，侵蚀气血，逐渐演变成各种疾病，不可不仔细考察。

Discourse states: Parasites are born with humans, hiding in concealed places. Their harm stems fundamentally from the deficiency of healthy qi (Zheng Qi). If one consumes raw and cold foods and is simultaneously affected by wind pathogens, various changes occur leading to their proliferation. Initially, they may seem harmless, but when severe, they can be fatal. Those skilled in preserving health eat bland diets, moderate desires, and eliminate the "Three Corpses" (Daoist concept of parasites residing in the body causing illness) early on, preventing disease before it arises. In this way, the nine types of parasites will dissolve imperceptibly. If one does not follow this path, one must use medicine to remove pests and eliminate worms, preventing their spread, as there are indeed medicines available for treatment.
The discourse states: The so-called "Nine Parasites" are named as follows: First is the Fu Chong (Hidden Worm), four fen long; second is the Hui Chong (Roundworm), one chi long; third is the Bai Chong (White Worm), one cun long; fourth is the Rou Chong (Flesh Worm), resembling rotten apricots; fifth is the Fei Chong (Lung Worm), resembling silkworms; sixth is the Wei Chong (Stomach Worm), resembling toads; seventh is the Ruo Chong (Weak Worm), resembling melon seeds; eighth is the Chi Chong (Red Worm), resembling raw meat; ninth is the Nuo Chong (Pinworm), resembling vegetable worms, extremely minute. These nine parasites reside within the intestines and stomach. If the qi of the fu and zang organs is sufficient, they cannot cause harm; however, when qi is deficient, they activate and change, eroding blood and qi, gradually developing into various diseases, which requires careful examination.
Guan Zhong Wan Formula for treating the activation of the nine parasites and the resulting various diseases:
Guan Zhong (Cyathulae Radix), Shi Can (Silex Siliceus, lightly fried, each 1 liang 1 fen), Ye Lang Ya (Acanthopanacis Senticosi Caulis, chopped), Lu (likely a typo or missing herb name in source, translated as Lu), Shu Qi (Perillae Fructus or similar depending on context, here kept as Shu Qi), Bai Jiang Can (Bombyx Batryticatus, lightly fried), Hou Po (Magnoliae Officinalis Cortex).
(Note: Source text lists ingredients but implies nine items, some details may be truncated in source).
Crush and sieve the above nine herbs into powder. Mix with refined honey to form pills. Place in a mortar, add a small amount of butter (Su), and pound until uniform and cooked. Form into pills the size of paulownia seeds. Take ten pills per dose, with warm rice water on an empty stomach, and again at noon and before bed.
Ji Zi Wan Formula for treating the nine parasites:

Place the pot on a pile of raw yellow earth. When slightly warm, add the eggs, stir appropriately, return to fire, and cook until suitable for pill formation. Form into pills the size of mung beans. Fast overnight. On an empty stomach, take twenty pills with millet drink; children take five pills.

(Note: Text mentions "six flavors" but lists four main ones plus She Xiang later).
Grind these into powder. Add a small amount of She Xiang (Moschus), grind uniformly. Use vinegar-boiled wheat paste to bind into pills, size of paulownia seeds. Take ten pills with warm water, before meals on an empty stomach.
Shi Liu Zhi Tang Formula for treating parasite activation, abdominal stabbing pain, vomiting clear fluid, dark yellow complexion, and worm-induced heart pain:

Chop the above seven herbs into sizes similar to hemp seeds. Take five qian bi per dose, with 1.5 cups of water, decoct to 0.8 cup, remove dregs, and take warm on an empty stomach.
Qi Xiang San Formula for treating adults and children with moving parasites in the abdomen and unceasing pain:
Gan Qi (Dried Lacca, fried until smoke appears, 2 liang), Xiong Huang (Realgar, ground, 5 qian), She Xiang (Moschus, ground, 1 qian).
