《千金要方》云∶人腹中生虫,大率有九,皆能食人脏腑。一曰伏虫,长四分,群虫之
主也。二曰蛔虫,长一尺,生发多则贯心而杀人。三曰白虫,长一寸,子孙相生,其母转大
,长至四五丈,亦能杀人。四曰内虫,状如烂杏,令人烦满。五曰肺虫,状如蚕,令人咳嗽
。六曰胃虫,状如虾蟆,令人呕吐胃逆喜哕。七曰弱虫,又名膈虫,状如瓜瓣,令人多唾。
八曰赤虫,状如生肉,令人肠鸣。九曰蛲虫,致细微,形如菜虫,居广肠之间,多则为痔,
剧则为癞。因人疮痍,即生诸痈疽、癣 、 疥、龋虫,无所不为,其害匪细。凡此
诸虫,大则根据附脏腑之间,小则侵蚀肌肤之内。若元气尚实,未为大害,稍有虚损,遂肆其
毒,甚至如劳瘵杀人,及传尸疰怪,或应声溪鼠之类。而非理之可测者多矣。业医者,不可
不究其所致之本,及治之之法也。
仲景曰∶狐惑之为病,状如伤寒,默默欲眠,目不得闭,起卧不安,蚀于喉为惑,蚀于
阴为狐,不欲饮食,恶闻食臭,其面目乍赤、乍白、乍黑。蚀于上部则声哑,甘草泻心汤
主之。蚀于下部则咽干,苦参汤洗之。蚀于肛者,雄黄熏之。愚按∶此仲景云狐惑之为病,
状如伤寒,则可见本非伤寒也。而后世即以狐惑为伤寒者,岂非误乎!
《千金要方》曰∶凡得伤寒及天行热病,腹中有热。又食少,肠胃空虚,三虫行作求食
,蚀人五脏及下部。若齿龈无色,舌上尽白,甚者唇里有疮,四肢沉重,忽忽喜眠,当数看
其上唇内有疮唾血,唇内如粟疮者,心内懊 痛闷,此虫在上蚀其五脏;下唇内生疮者
,其人喜眠,此虫在下,蚀其下部。人不能知,可服此蚀虫药,不尔, 虫杀人。又曰
∶凡患湿 者,多是热病后,或久泻不止,或有客热结在腹中,或易水土,温凉气着,
多生此病。亦有干 ,不甚泻痢,而下部疮痒。不问干湿,久则杀人。凡湿得冷则苦痢
,单煮黄连及艾叶、苦参之属,皆可用之。若病患齿龈无色,舌上白者,或喜眠烦愦,不知
痛痒处,或下痢,急治下部。不晓此者,但攻其上,不以下部为意,下部生虫,虫蚀其肛,
肛烂见五脏便死,烧艾于竹筒熏之。
The *Qianjin Yaofang* states: The parasites that arise in the human abdomen are generally of nine types, all capable of eroding the internal organs. The first is called *Fuchong* (Hidden Worm), measuring four fen in length, which serves as the master of all worms. The second is called *Hui Chong* (Roundworm), measuring one chi in length; if numerous, it may pierce the heart and cause death. The third is called *Bai Chong* (White Worm), measuring one cun in length; its offspring multiply continuously, with the mother growing larger, reaching lengths of four to five zhang, also capable of causing death. The fourth is called *Nei Chong* (Internal Worm), resembling rotten apricots, causing irritability and fullness. The fifth is called *Fei Chong* (Lung Worm), resembling silkworms, causing coughing. The sixth is called *Wei Chong* (Stomach Worm), resembling a toad, causing vomiting, rebellious stomach qi, and frequent belching. The seventh is called *Ruo Chong* (Weak Worm), also known as *Ge Chong* (Diaphragm Worm), resembling melon seeds, causing excessive salivation. The eighth is called *Chi Chong* (Red Worm), resembling raw meat, causing borborygmus (bowel sounds). The ninth is called *Tao Chong* (Pinworm), extremely minute, resembling vegetable larvae, residing between the broad intestines; when numerous, they cause hemorrhoids, and when severe, they cause leprosy-like conditions. Due to skin sores and ulcers, various abscesses, tinea, scabies, and dental caries worms arise, doing no evil they do not commit, their harm being significant. All these worms, whether large or small, either attach themselves between the internal organs or erode within the skin and muscles. If the primordial qi (*Yuan Qi*) remains substantial, they are not a major threat; however, with slight deficiency or damage, they unleash their toxicity, even killing like *Lao Zhai* (Consumption/Tuberculosis) or spreading through *Chuan Shi Zhu Guai* (Transmitted Corpse Parasitic Diseases), or involving phenomena like the "Echoing Stream Rat," many of which defy rational explanation. Practitioners of medicine must not fail to investigate the root causes of their emergence and the methods of treatment.
Zhang Zhongjing stated: In the disease of *Hu Huo* (Fox-Hu Syndrome), the presentation resembles *Shang Han* (Cold Damage); the patient is silent and desires sleep but cannot close their eyes, feeling restless sitting or lying down. Erosion of the throat is termed *Huo*, while erosion of the yin organs is termed *Hu*. There is a lack of appetite and aversion to food odors; the facial complexion alternates between red, white, and black. If erosion occurs in the upper part, hoarseness results, treated primarily with *Gancao Xiexin Tang* (Licorice Decoction for Draining the Epigastrium). If erosion occurs in the lower part, dryness of the throat results, washed with *Kushen Tang* (Sophora Root Decoction). If erosion occurs at the anus, fumigation with *Xionghuang* (Realgar) is used. I observe: Since Zhang Zhongjing stated that the symptoms of *Hu Huo* resemble *Shang Han*, it is evident that this condition is originally not *Shang Han*. Yet later generations equated *Hu Huo* with *Shang Han*; is this not an error?
The *Qianjin Yaofang* states: Whenever one contracts *Shang Han* or epidemic febrile diseases, heat accumulates in the abdomen. Coupled with poor intake and empty intestines and stomach, the three worms become active seeking food, eroding the five viscera and the lower body. If the gums appear colorless and the tongue is entirely white, or severely, sores appear inside the lips, accompanied by heavy limbs, mental confusion, and drowsiness, one should frequently inspect for sores and spitting of blood inside the upper lip, or millet-grain-like sores inside the lips; this indicates inner restlessness, pain, and oppression, signifying worms eroding the five viscera from above. If sores appear on the inside of the lower lip, the person tends toward sleep, indicating worms eroding the lower body from below. If people do not understand this, they may take vermifuge medicines; otherwise, the worms will kill. It further states: Those suffering from *Shi Bi* (Dampness Bi Syndrome) often do so after febrile diseases, or due to chronic diarrhea, or because pathogenic heat is knotted in the abdomen, or due to acclimatization issues where warm and cold qi invade. Dry *Bi* may not involve severe diarrhea but presents with itching sores in the lower parts. Whether wet or dry, prolonged duration leads to death. When dampness encounters cold, it causes painful dysentery; decocting alone *Huanglian* (Coptis Rhizome), *Ai Ye* (Mugwort Leaf), or *Kushen* (Sophora Root) is applicable. If the patient has colorless gums, a white tongue, or prefers sleep with irritability and confusion, losing sensation of pain and itch, or suffers dysentery, urgent treatment of the lower part is required. Those ignorant of this principle attack only the upper part, neglecting the lower part; consequently, worms arise in the lower part, eroding the anus until it rots exposing the viscera, leading to death. Moxa burned in a bamboo tube should be used for fumigation.
