【蜗牛】
味咸，性寒，有小毒，未记载归经。主治贼风引起口眼歪斜，惊风导致的筋脉拘挛，收敛大肠脱肛及痔疮疼痛，消除消渴病和疳积。使用时需火炒后应用。
按语：蜗牛之所以得名，是因为其头部有角状突起类似牛。夏季时它们往往攀高，一旦涎液流尽就会枯死，必须用火炒制，确实是为了去除其寒性（并醒酒止渴、治疗痔疮）。品种繁多，功效大致相同，此处不再赘述。
【僵蚕】
味咸、辛，性微温，有小毒，入心、肝、脾、肺四经。主治风温引起的牙关紧闭、失音，疔疮毒邪与风痰结滞，皮肤感觉异常如虫行，小儿惊痫夜间啼哭，女子崩漏带下赤白，止阴部瘙痒，驱除三虫，消除黑斑。需用米泔水浸泡以去除涎液，炒去丝后使用。忌与茯苓、茯神、萆薢、桑螵蛸、桔梗、雄蚕蛾同用。性热，主治固精强阳，性交不知疲倦。
按语：朱丹溪说：白僵蚕属火而兼具土、金、水之性，因此能入心、肝、脾、肺四经。凡使用须选头尾完整的，效力加倍，蚕蛾也是如此。
雷公说：凡使用先需用糯米淘米水浸泡一天，待蚕桑的涎液流出浮在水面上，然后捞出用微火焙干，以……
【蝉蜕】
味咸、甘，性寒，无毒，未记载归经。主催生及排出胎盘，通乳汁，止夜啼惊痫，驱逐邪热，杀疳蛊，也能止渴。
按语：蝉有五种，陈藏器已详细辨别，如今选用形体极大且声音极高，一鸣而不停断的，入药效果最好。西川有一种蝉花，是蝉在壳中出不来而化为花，从头顶生出，功用大致相同，故不另载。
【地龙】
味苦、甘，性平，有小毒，未记载归经。主治五痔、肠风便血，翻胃、鼻衄，腹痛，积聚疝气及阴囊肿痛。需用酒煮熬制后使用，畏桔梗、麦冬。
按语：地龙也有数种，只有苍白色、脚像猪蹄的是佳品，其余都不宜使用，其骨切忌入口，令人消瘦。
[Helix Aspersa / Snail]
Taste: Salty. Nature: Cold. Toxicity: Slightly toxic. Meridian tropism: Not recorded. Indications: Mainly treats facial paralysis due to thief wind (wind-stroke), muscle spasms and contractures of tendons and vessels due to infantile convulsions; astringes large intestine prolapse and hemorrhoidal pain; eliminates thirst and malnutrition syndrome in children. Preparation: Stir-fry over fire before use.
Note: The name "Snail" is derived from the horn-like protrusions on its head resembling that of an ox. In summer, they often climb high; once their mucus flows out completely, they wither and die. Fire-frying is necessary indeed to remove their cold nature [and to awaken thirst and treat hemorrhoids]. There are various species with approximately similar efficacy; further details are omitted here.
[Bombyx Batryticatus / Stiff Silkworm]
Taste: Salty, Pungent. Nature: Slightly warm. Toxicity: Slightly toxic. Meridian tropism: Enters the Heart, Liver, Spleen, and Lung meridians. Indications: Mainly treats trismus and aphonia due to wind-warmth; carbuncles and toxins combined with wind-phlegm stagnation; skin sensations like insects crawling; infantile convulsions and night crying; metrorrhagia and leukorrhea (red and white discharge) in women; stops pruritus vulvae; expels three types of parasites; removes dark spots. Preparation: Soak in rice washing water to remove mucus, stir-fry to remove silk threads. Contraindications: Adverse interaction with Poria cocos (Fuling), Poria cocos with pine root (Fushen), Dioscorea hypoglauca (Bixie), Mantis ootheca (Sangpiaoxiao), Platycodon grandiflorus (Jiegeng), and male silkworm moth (Xiong can'e). Nature: Hot. Indications: Consolidates essence and strengthens yang; prevents fatigue during sexual intercourse.
Note: Zhu Danxi stated: Bai Jiangcan belongs to Fire but also possesses Earth, Metal, and Water qualities, which explains its entry into the Heart, Liver, Spleen, and Lung meridians. When used, those with intact heads and tails are twice as potent; the same applies to silkworm moths.
Lei Gong stated: For preparation, first soak in glutinous rice washing water for one day. Wait until the silkworm/mulberry mucus floats to the surface like snail mucus, then drain and dry over a mild fire...
[Cicada Slough / Periostracum Cicadae]
Taste: Salty, Sweet. Nature: Cold. Toxicity: Non-toxic. Meridian tropism: Not recorded. Indications: Mainly promotes delivery and expulsion of the placenta; unblocks lactation; stops night crying and infantile convulsions; drives out pathogenic heat; kills malnutrition parasites; also relieves thirst.
Note: There are five types of cicadas, distinguished by Chen Cangqi. Currently, those that are extremely large in size, produce very loud sounds, and sing continuously without interruption are considered best for medicinal use. In Western Sichuan, there is a type called "Cicada Flower," where the cicada fails to emerge from its shell and transforms into a flower growing from its crown. Its efficacy is roughly the same, so it is not listed separately.
[Pheretima / Earthworm]
Taste: Bitter, Sweet. Nature: Neutral. Toxicity: Slightly toxic. Meridian tropism: Not recorded. Indications: Mainly treats five types of hemorrhoids, intestinal wind with bloody stool, vomiting (fanwei), epistaxis, abdominal pain, accumulation hernia, and swelling/pain of the scrotum. Preparation: Decoct or simmer in wine. Adverse interactions: Adverse interaction with Platycodon grandiflorus (Jiegeng) and Ophiopogon japonicus (Mendong).
Note: There are several varieties of earthworms. Only those that are pale white with feet resembling pig trotters are considered superior; others are not suitable for use. Their bones must never be ingested, as they cause emaciation.
