（卵生的）谷虫，专门作用于肠胃。味道苦，性质寒凉。它产生于粪便之中，因此仍然利用它进入腹部消除积滞的特性，使其不损伤人体的正气。使用方法是将谷虫漂洗干净后炙黄，研成粉末调服。另外，取几十只蛤蟆，打死放在镡（一种容器或器具）内，放入谷虫让其吃尽，然后淘除污秽之物，将剩下的谷虫焙干。凡是小儿患疳积，出现腹部胀大、腿部瘦弱、眼睛被翳膜遮挡等症状，以及大人因热结导致胡言乱语、毒利伴随呕吐的情况，都适宜服用此药，没有不立即见效的。因此，对于鼻部和齿部的疳疮，取这种有尾的谷虫烧成灰，一钱重，与旧衣服烧成的灰混合均匀，频繁吹入患处，效果最好。至于治疗骨槽风取牙，用白马脑上肉一两二斤，等待生出蛆虫，喂给一只乌骨白鸡食用，收集其粪便阴干，每用一钱加入砂一钱，研磨均匀，用少许涂抹疼痛处，片刻即可脱落。这些都是利用秽浊之物来化解秽浊之邪，意在让药物深入骨肉钻透，没有其他深奥的含义。
《内经》说：营气运行不畅，逆乱于肌肉纹理之间，就会发生痈肿。又说：各种疼痛、疮疡和瘙痒，都属于心火。再看丹溪先生说过：痈疽都是因为阴阳之气相互阻滞而产生的。那么痈疽的发生，固然需要内外因素共同作用，而不仅仅局限于肌肉纹理间的病变。但是，如果毒邪尚未深入，情况类似于伤寒初期，邪气刚刚在体表，用药只宜升散发表，而不应该立即使用苦寒药物，以使毒邪从外部发散。如果稍微向内陷入造成祸殃，那么毒势就会缠绵不断，并且有毒邪攻心的必死征候！我考察发毒的药物，品类非常多。凡是三阳经常用的升麻、柴胡、葛根、羌活、防风、白芷、荆芥、薄荷、桔梗等药物，哪一样不是发散毒邪的最佳选择？穿山甲、皂角等药物，哪一样不是驱赶毒邪、追踪毒邪的方剂？至于蜈蚣能驱风通瘀散结，蛇蜕能驱风辟恶，野菊花能散火逐气，王不留行能行气宣滞，都是祛除消散恶毒的药剂。此外还有蟾酥、蟾蜍，力量能透拔风邪火毒；象牙力量能拔毒使之外脱；枫香力量能透毒外出；人牙力量能入肾推毒；胡桐泪力量能引吐膈部热毒；轻粉、黄丹、银朱，力量能制约外部痈疽疮疥；蝼蛄、蓖麻，力量能通水开窍，拔毒向外行。如果在芙蓉花，虽然药物属性清凉，但仍然兼有表性，因此用它作为敷贴箍束毒邪的方剂。其余治疗毒邪的药剂，仔细审视其具有苦寒性质的，应当另外列入解毒类中，不可归入发毒剂的类别，以便人们都知道毒邪应从外部发散，不能竟然使用内陷的药物。
(Oviparous) Gu Chong (Valvatae Concha, a type of snail shell used in TCM for resolving food stagnation), specifically enters the stomach and intestines. Its taste is bitter and its nature is cold. It originates from feces; therefore, it is still utilized for its ability to enter the abdomen and resolve stagnation, ensuring it does not damage the healthy Qi (Vital Energy). The method involves washing it clean, roasting it until yellow, grinding it into powder, and taking it with water. Alternatively, take dozens of Bufo bufo gargarizans (Toad), kill them, place them in a container, introduce Gu Chong inside to consume them completely, then wash away the filth, dry the remaining Gu Chong by baking. For children suffering from Gan Ji (Malnutrition/Infantile Malabsorption Syndrome) presenting with abdominal distension, weak legs, and corneal opacity covering the eyes, as well as adults experiencing delirium due to heat accumulation, toxic dysentery accompanied by vomiting, this medicine is suitable for all cases, yielding immediate effect without exception. Therefore, for nasal and dental Gan Chuang (Gum Disease/Fistula), burn one qian (approx. 3-5g) of these tailed Gu Chong to ash, mix evenly with ash from old clothes, and blow frequently into the affected area for best results. Regarding the extraction of teeth for bone-related infections, use one or two jin (approx. 500-1000g) of meat from the top of a white horse's brain, wait for maggots to breed, feed them to one black-boned white chicken, collect the feces, dry them in shade, mix one qian with Sha (likely referring to a mineral drug like Realgar or similar, contextually ambiguous but kept as 'Sha'), grind uniformly, apply a small amount to the painful area, and the tooth will fall off in a moment. All these methods utilize foul substances to counteract foul pathogens, aiming for penetration into bone and flesh, with no other profound meaning.
The *Nei Jing* (Inner Canon) states: When Ying Qi (Nutritive Qi) fails to flow smoothly and reverses into the muscle tissue, abscesses and swellings arise. It also states: All pain, sores, itching, and rashes belong to Heart Fire. Furthermore, observing Dan Xi's words: Abscesses and carbuncles arise from the stagnation of Yin and Yang. Thus, the onset of abscesses and carbuncles necessarily involves both internal and external factors, not merely lesions seen within the muscle tissue. However, if the pathogenic toxin has not penetrated deeply, resembling early-stage Shang Han (Cold Damage) where the pathogen is initially at the exterior, medications should only be suitable for ascending and dispersing, rather than immediately using bitter-cold herbs, so that the toxin can be expelled from the exterior. If it slightly penetrates inward causing harm, the toxic condition will become lingering and persistent, leading to fatal signs of toxin attacking the Heart! I have examined drugs for Fa Du (Expelling Toxins); there are many categories. Herbs such as Sheng Ma (Cimicifugae Rhizoma), Chai Hu (Bupleuri Radix), Ge Gen (Puerariae Lobatae Radix), Qiang Huo (Notopterygii Rhizoma et Radix), Fang Feng (Saposhnikoviae Radix), Bai Zhi (Angelicae Dahuricae Radix), Jing Jie (Schizonepetae Spica), Bo He (Menthae Haplocalycis Herba), and Jie Geng (Platycodonis Radix) used in the Three Yang meridians—none are not among the best for expelling and scattering toxins. Shan Jia (Manis Squama, Pangolin Scales) and Zao Jiao (Gleditsiae Sinensis Spina)—none are not formulas for driving out and pursuing toxins. As for Wu Gong (Scolopendra), it can dispel wind, unblock stasis, and dissipate nodules; She Tui (Bombyx Batryticatus, Shed Skin of Silkworm Spider) can dispel wind and ward off evil; Ye Ju Hua (Chrysanthemi Indici Flos) can scatter fire and drive away qi stagnation; Wang Bu Liu Xing (Vaccariae Semen) can promote qi circulation and relieve stagnation. All are agents for removing and dissipating malignant toxins. Externally, Chan Su (Bufonis Venenum, Toad Venom) and Chan Chu (Bufo bufo gargarizans) have the power to penetrate and extract wind and fire toxins; Xiang Ya (Elephantis Dentis Os, Elephant Tooth) has the power to pull toxins outward; Feng Xiang (Liquidambaris Resina) has the power to transmit toxins outward; Ren Ya (Hominis Dentis Os, Human Tooth) has the power to enter the Kidney and push out toxins; Hu Tong Lei (Tamarisci Fucus, Tamarisk Gum) has the power to induce vomiting of heat toxins in the diaphragm; Qing Fen (Calomelas), Huang Dan (Lithargyrum), and Yin Zhu (Cinnabaris Rubra) have the power to control external abscesses, sores, and scabies; Lou Fu (Aspidis Ascaris, Mole Cricket) and Bi Ma (Ricini Fructus, Castor Bean) have the power to open water passages and orifices, pulling toxins outward. In the case of Fu Rong Hua (Hibisci Mutabilis Flos), although the herb is cooling in nature, it still possesses exterior-releasing properties; thus, it is used in formulas for applying and binding toxins. Other treatments for toxins, upon careful examination of those with bitter-cold tastes, should be listed separately under Jie Du (Resolving Toxins), and must not be included in the category of Fa Du (Expelling Toxin) agents, so that people understand toxins should be expelled from the exterior and not treated with internal-depressing medicines that cause sinking inward.
