《泊宅编》云∶永州通宅听军员毛景，得奇疾，每语喉中必有物作声相应。有道人教之
读《本草》药名，至兰而默然，遂取兰捩汁而饮之，少顷吐出肉块，长二寸余，人形悉具。
刘思在永州亲见其事。《千金翼》云∶兰主疳蚀，则固杀虫物尔。

蔡定夫戡之子康积，苦寸白虫。医者教之以月初三日前，先炙猪肉一脔，置口中，咀咽
其津而勿食，诸虫闻香争咂，如箭攻攒，却以槟榔细末一两，取石榴东引根煎汤调服之。蔡
如其言，不两时，腹中雷鸣急泻，虫下如倾，以杖挑之，皆连绵成串，其长几丈，尚蠕蠕能

古称九虫∶一曰伏虫，长四寸，为群虫之长。二曰白虫，相生至多，形长一寸，其母长

《泊宅编》记载：永州通判衙门听事军员毛景，患了一种奇特的疾病，每次说话时喉咙中必定有物体发出声音与之相应。有一位道士教他诵读《本草》中的药名，当读到“兰”字时，他默然无声（即喉中异物不再发声），于是取兰草的汁液饮用，不久后吐出一块肉状物，长约两寸多，人形俱全。刘思在永州亲眼目睹了这件事。《千金翼方》记载：兰主治疳蚀症，那么它确实是杀虫的药物。
陈正敏《遁斋闲览》记载：杨姓男子，中年患上奇异疾病，每次发言应答时，腹中有小虫模仿他的声音，几年间，那声音逐渐变大。一位道士看见后惊讶地说：“这是应声虫。”如果长久不治疗，会波及妻子儿女，应当诵读《本草》，遇到虫子不回应（即沉默）的药名时，那个药名对应的药物就能治愈此病。（原文此处中断，意指找到对应药物即可治愈）。
蔡定夫戡的儿子蔡康积，深受寸白虫（绦虫）之苦。医生教他在农历月初三日前，先烤一块猪肉，放入口中，咀嚼吞咽其津液而不吞食肉块，各种虫子闻到香味争相吸吮，如同箭矢聚集一般，然后用一两槟榔细末，取石榴树向东生长的根部煎汤调服。蔡康积照做，不到两个时辰，腹中雷鸣般急泻，虫子排出如倾泻一般，用棍棒挑开看，都连绵成串，长度几乎有几丈，仍然蠕蠕能动，于是全部放入火中烧掉，宿疾顿时痊愈。
古书称九种寄生虫：第一种叫伏虫，长四寸，是群虫的首领。第二种叫白虫，繁殖极多，形状长一寸，其母体长达四、五尺。第三种叫肉虫，形状像烂杏，使人烦闷。第四种叫肺虫，形状像蚕，使人咳嗽且声音嘶哑。第五种叫胃虫，形状像蛤蟆，使人呕吐逆气。第六种叫弱虫，形状像瓜瓣，使人唾液增多。第七种叫赤虫，形状像生肉，使人肠鸣。第八种叫蛲虫，极其微小，形状像菜虫，居住在洞肠之间，停留处会导致痔漏、痈疽等各种疮疡。第九种叫蛔虫，长一尺，若贯穿心脏则致死。又有三种尸虫，形状像大马尾，附着在筋上依托脾脏居住，都有头尾，各长三寸。还有劳虫、膈噎虫、癞虫、蛊虫、狐惑虫等，难以一一列举，医生可以推究其类而进行治疗。
The *Bozhai Bian* records: Mao Jing, a military officer in the yamen of Yongzhou Prefecture, suffered from a strange disease. Whenever he spoke, an object in his throat would make a sound in response. A Daoist priest instructed him to recite the names of herbs from the *Bencao* (Materia Medica). When he reached the name "Lan" (Orchid), he fell silent (the throat object ceased responding). He then drank the juice extracted from Lan, and shortly after, vomited out a piece of flesh-like matter, slightly over two cun long, with a complete human form. Liu Si witnessed this event personally in Yongzhou. The *Qianjin Yifang* states that Lan treats gan erosion (ulcerative conditions caused by parasites or deficiency heat); thus, it is indeed an insecticidal substance.
Chen Zhengmin's *Dunzhai Xianlan* records: A man surnamed Yang developed a bizarre illness in middle age. Whenever he spoke or answered, small insects in his abdomen mimicked his voice. Over several years, the sound gradually grew louder. A Daoist priest saw this and exclaimed in surprise, "This is a 'responding-sound insect' (Yingsheng Chong)." If left untreated for a long time, it will spread to his wife and children. One should recite the *Bencao*; when encountering a herb name that does not elicit a response from the insect, that herb will cure the condition. (Note: The original text here is incomplete, implying that finding the non-responding herb identifies the cure).
Cai Kang, son of Cai Dingfu Kan, suffered bitterly from Ascaris lumbricoides (specifically referring to tapeworms/segmented worms, known as Cunbai Chong). The physician instructed him to roast a piece of pork on the third day before the beginning of the lunar month. He was to place it in his mouth, chew and swallow the saliva without swallowing the meat. The various insects, attracted by the aroma, would swarm to suck at it like arrows gathering. Then, one liang of fine powder of Areca Seed (Binglang) should be taken, mixed with a decoction made from the eastward-growing roots of Pomegranate Bark (Shiliu Pi), and administered orally. Cai followed these instructions. Within less than two shi (four hours), thunderous sounds erupted in his abdomen accompanied by urgent diarrhea. The worms were expelled in great quantities; when probed with a stick, they were found to be connected in long chains, nearly ten zhang in length, still wriggling. They were all thrown into fire and burned, and his chronic ailment was instantly cured.
Ancient texts describe nine types of intestinal parasites: 1. Fu Chong (Hidden Worm), four cun long, is the leader of the group of worms. 2. Bai Chong (White Worm), reproduces excessively, one cun long in shape, while its mother can reach four or five chi in length. 3. Rou Chong (Flesh Worm), shaped like a rotten apricot, causes mental restlessness and oppression. 4. Fei Chong (Lung Worm), shaped like a silkworm, causes coughing and hoarseness. 5. Wei Chong (Stomach Worm), shaped like a toad, causes vomiting and regurgitation. 6. Ruo Chong (Weak Worm), shaped like melon seeds, causes excessive salivation. 7. Chi Chong (Red Worm), shaped like raw meat, causes borborygmus (bowel sounds). 8. Tiao Chong (Pinworm), extremely minute and shaped like vegetable worms, resides in the intestinal cavities; its presence leads to hemorrhoids, fistulas, carbuncles, sores, and other ulcers. 9. Hui Chong (Roundworm), one chi long; if it pierces the heart, it causes death. There are also three types of Shī Chong (Corpse Worms), shaped like large horse tails, thin and attached to the tendons, relying on the Spleen for residence, possessing both head and tail, each three cun long. Additionally, there are Lao Chong (Consumption Worms), Ge Ye Chong (Dysphagia Worms), Lai Chong (Leprosy Worms), Gu Chong (Gu Poison Worms), and Hu Huo Chong (Fox-Haunting Worms), which are difficult to list completely. Physicians may treat them by inferring their categories.
