【文蛤】
气性平，味咸。无毒。
《本草》记载：主治恶疮，腐蚀五痔，咳逆及胸痹，腰痛胁肋拘急，鼠瘰（淋巴结结核），肛门出血，崩中漏下（妇科非经期大量出血或淋漓不断）。能利水。治疗急性疳积腐蚀口鼻，数日内腐烂殆尽，濒临死亡，将其烧成灰，用腊月猪脂调和后涂抹患处。（此处指）坠痰软坚，止渴，收涩固摄，即蛤粉。咸味能入肾，可以制约水邪。文蛤的尖端带有紫色斑点。
【蜣螂】
气微寒，味苦，平。有毒。
《本草》记载：主治眼中赤痛，目伤流泪，瘀血及血闭，寒热酸痛，无子（不孕）。炒制，去除翅膀和足。
【䗪虫】

《本草》记载：主治驱逐恶血、瘀血及月经闭止，破除血瘕积聚，治疗不孕，通利水道，堕胎。需炒用。畏盐。
苦味入血分，咸味能破血，张仲景在抵当汤中使用虻虫、水蛭，是利用其咸苦之性来泄除蓄积之血。所以《内经》说：“有病则病受之，不会伤害人体。”虽然可以使用这类药物，但也不甚安稳。不如使用四物汤加上酒浸的大黄，各取一半剂量，攻下瘀血，效果极佳。
【土鳖虫】
味咸，寒。有毒。
《本草》记载：主治心腹间寒热战栗，血积症瘕，破除坚硬结块，通下血闭，对生育大有益处。张仲景主治久病形成的瘕结，有大黄䗪虫丸。
《衍义》记载：乳汁不通时，研磨一枚土鳖虫，加入半合水，过滤取清汁服用。不要让服药人知道。
【鼠妇】

《本草》记载：主治气癃导致的小便不通，妇人月经闭止，血瘕引起的癫痫痉挛，寒热，通利水道。张仲景治疗久疟疾，在大鳖甲丸中使用它。因为它主治寒热。
《衍义》记载：鼠妇是湿生虫。
【蜘蛛】
微寒。
《本草》记载：主治大人小儿狐疝。七月七日采集其网，治疗健忘。张仲景治疗杂病。对于狐疝，睾丸偏大偏小，时时上下移动者，用蜘蛛十四个，炒焦，加桂枝半两。研细为散剂。每次八分匕，用酒调服，每日两次。制成蜜丸也可以。

It can promote urination. It treats acute gan accumulation eroding the mouth and nose, causing rotting within a few days to the point of near death; burn it to ash, mix with lard from the twelfth lunar month, and apply externally.
