夫九虫者，一曰伏虫，长四寸；二曰蛔虫，长一尺；三曰白虫，长一寸；四曰肉虫，状
如烂杏；五曰肺虫，状如蚕形；六曰胃虫，状如虾蟆；七曰弱虫，状如瓜瓣；八曰赤虫，状
如生肉；九曰蛲虫，至细微，形如菜虫。伏虫，群虫之主也。蛔虫贯心则杀人。白虫相生，
子孙转大，长至四、五尺，亦能杀人。肉虫令人烦满。肺虫令人咳嗽。胃虫令人呕吐，胃逆
喜哕。弱虫又名隔虫，令人多唾。赤虫令人肠鸣。蛲虫居胴肠，多则为痔，剧则为癞，因人
疮处，以生诸痈疽、癣 、 疥。龋虫无所不为，人亦不必尽有，有亦不必尽多，或偏有，
或偏无者。此诸虫根据肠胃之间，若腑脏气实，则不为害。若虚则能侵蚀，随其虫之动而变成
诸患也。（《外台》卷二十六）

The nine types of parasites are: the first is called Fuchong (Hidden Worm), four cun in length; the second is called Huichong (Roundworm), one chi in length; the third is called Baichong (White Worm), one cun in length; the fourth is called Rouc (Flesh Worm), resembling a rotten apricot; the fifth is called Feichong (Lung Worm), resembling a silkworm; the sixth is called Weichong (Stomach Worm), resembling a toad; the seventh is called Ruochong (Weak Worm), resembling a melon seed; the eighth is called Chichong (Red Worm), resembling raw meat; the ninth is called Nuochong (Pinworm), extremely minute, resembling a vegetable worm. Fuchong is the leader of the group of worms. If Huichong penetrates the heart, it causes death. Baichong reproduces, and its descendants grow larger, reaching four or five chi in length, which can also cause death. Rouc causes vexation and fullness. Feichong causes coughing. Weichong causes vomiting and a tendency for stomach qi to rebel with belching. Ruochong, also known as Gechong (Diaphragm Worm), causes excessive salivation. Chichong causes borborygmus (bowel sounds). Nuochong resides in the tongchang (rectum); if numerous, it leads to hemorrhoids; if severe, it leads to leprosy-like conditions; entering human sores, it generates various yongju (carbuncles and ulcers), xuan (tinea), and jie (scabies). Quchong (Tooth Worm) does everything possible; humans do not necessarily have them all, nor must they be numerous; some may have them predominantly, others not at all. These various worms reside between the fu organs and chang organs. If the qi of the fu and zang organs is solid, they do not cause harm. If deficient, they can erode the body, transforming into various ailments according to the movement of the specific worm. (From *Waitai Miyao*, Vol. 26)
