【地胆】
味辛，性寒，有毒。主治鬼疰（一种具有传染性、症状迁延的虚劳病证），寒热往来，鼠瘘（颈部淋巴结结核），恶疮，死肌（坏死的肌肉组织），破除症瘕（腹内结块），堕胎（导致流产）。能腐蚀疮疡中的腐肉，若将药粉纳入鼻中，服用一刀圭（古代量词，约0.5-1克）即可排出。又名青，又名青蛙。产于汶山川谷，八月采收。畏甘草。真正的地胆出自梁州，形状像带翅膀的大蚂蚁；伪品则是由斑蝥变化而来，形状像大豆，大多治疗作用大致相同，但必定不如真品有效，因此有“青”的名称。“地”字乃是异体字，恐怕是沿袭下来的错误罢了。
〔谨案〕形状像大蚂蚁的，如今在益州所见到的就是这种。形状像大豆的，未曾见过。
【马刀/蛤蜊类】
味辛，微寒，有毒。主治漏下赤白（妇女非经期阴道出血，色红白相兼），寒热往来，破除石淋（泌尿系结石），杀灭禽兽和贼鼠。清除五脏间的热邪，去除肌肉中的鼠瘘，止利机关（此处疑为衍文或指通利关节，原文语境稍显晦涩，暂译为止滑脱或通利）。使用时应当经过炮制，否则遇水会腐烂进入肠道伤人。又有人说遇水反而好。又名马蛤。产于江湖之中。李云说生于江汉中，长六、七寸，汉中人名为单姥，也食用其肉，肉质像蚌。现在的人大多不认识它，大体上像现在的KT（注：此处原文可能有误或指代不明，依原文直译），而非普通的蛤蜊。方书中用到它的很少。凡是这类东西都不可多吃，且不正规入药，只有蛤蜊煮食可以解酒。蚬壳陈久者可以止痢。车螯、蚶、蛎等属类，也可以食用，无补益也无损害，未见其主要功效。野鸡入大水变为，说是大蛤，其实是蚌，煮食各种蜊蜗与菜，都不利于人。
〔谨案〕蚬，性冷，无毒。主治时气（季节性流行病）开胃，压制丹石药（矿物药）的药性，以及疔疮，下行湿气，下乳，糟煮服用良好。生浸取汁，洗疔疮。多食引发咳嗽，并引起冷气，消肾。陈旧的壳，治疗阴疮，止痢。蚬肉，性寒，去除暴热，明目，利小便，下行热气，治疗香港脚（脚气病），湿毒，解酒毒，目黄。浸取汁服用，主治消渴（糖尿病类疾病）。烂壳，性温，烧成白灰后冲服，主治反胃，吐食，去除心胸痰水。壳陈久，治疗胃反及失精。
[Di Dan]
Taste: Pungent; Nature: Cold; Toxicity: Toxic.
Indications: Governs Gui Zhu (a contagious, lingering consumptive disease), alternating chills and fever, Shu Lou (cervical lymph node tuberculosis), malignant sores, dead muscle tissue, breaking up Zheng Jia (abdominal masses), and inducing abortion. It can erode foul flesh in sores. If the powder is insufflated into the nose, a dose of one Dao Gui (an ancient unit of measure, approx. 0.5-1g) will cause expulsion.
Synonyms: Qing, Qing Wa.
Habitat: Produced in valleys of Mount Wen; harvested in the eighth lunar month.
Incompatibility: Averse to Gan Cao (Glycyrrhizae Radix et Rhizoma).
Description: The genuine Di Dan originates from Liang Zhou, resembling a large winged ant. The counterfeit is transformed from Ban Mao (Mylabris), resembling a soybean. Their therapeutic effects are largely similar, but the counterfeit cannot match the efficacy of the genuine product; hence the name "Qing". The character "Di" is likely an variant form, probably an error passed down through generations.
[Commentary]: Those resembling large ants are seen today in Yi Zhou. Those resembling soybeans have not been observed.
[Ma Dao / Clam-like Species]
Taste: Pungent; Nature: Slightly Cold; Toxicity: Toxic.
Indications: Governs red and white leukorrhea (non-menstrual vaginal discharge with red and white colors), alternating chills and fever, breaking up Shi Lin (urinary calculi), and killing birds, beasts, and rats. Clears heat between the five zang organs, removes Shu Lou from muscles, and regulates joint function (Note: Text implies regulating joints or stopping slippage). When used, it must be processed; otherwise, upon contact with water, it may rot and damage the intestines. Another view states that water enhances its effect.
Synonym: Ma Ha.
Habitat: Produced in rivers and lakes.
Li Yun stated it grows in the Jianghan region, measuring six to seven cun. People in Han call it "Dan Lao" and consume its meat, which resembles clam meat. Most people today do not recognize it; it generally resembles modern [KT - text unclear/unidentified], rather than common clams. It is rarely used in prescriptions. Generally, such species should not be consumed in large quantities and are not standard medicinal materials. Only Ge Li (Clam) boiled can resolve alcohol intoxication. Old Xian (Corbicula) shells can stop diarrhea. Che Ao (Tridacna), Han (Arcidae), and Li (Oyster) belong to this category and can be eaten, offering no particular benefit or harm, with no specific primary indications recorded.
When a pheasant enters deep water, it transforms into [Species Name Missing], said to be a large clam, but is actually a mussel. Boiling and eating various clams, snails, and vegetables is detrimental to humans.
[Commentary]: Xian (Corbicula fluminea), cold nature, non-toxic. Governs seasonal epidemic diseases, opens the stomach, counteracts the toxicity of Dan Shi medicines (mineral drugs), treats Ding Chuang (furuncles), drains dampness, promotes lactation. Cooked with lees is beneficial. Fresh juice applied externally washes Ding Chuang. Excessive consumption induces cough, causes cold qi, and depletes the kidneys. Old shells treat yin sores and stop diarrhea. Xian meat, cold nature, removes sudden heat, brightens the eyes, promotes urination, drains hot qi, treats Hong Kong Jiao (Charley Horse/Beriberi), damp-toxin, resolves alcohol toxin, and treats yellow eyes. Juice taken internally governs Xiao Ke (wasting-thirst syndrome). Rotten shells, warm nature, burned to white ash and taken with water, govern regurgitation, vomiting, and removes phlegm-fluid from the chest and heart. Old shells treat gastric regurgitation and seminal emission.
