【龟甲】又名败龟板。《格物考》记载：天上有早春时的雷震，山中有自然死亡的乌龟。乌龟听到雷声，口中含着的处于冬眠状态的东西就会出来。（此处原文有缺漏或排版错误，意指龟感应雷声而出蛰）
【性味归经与功效】味道咸、甘，气平。被湿气浸染的龟甲有毒，未被湿气浸染的无毒。气味均属阴，入足少阴肾经。畏沙参。具有补阴的作用。主治……（原文此处有严重缺漏，似为“主久痢”、“久疟”等，但原文仅存“主阴及久借其甲皆鹿五产下气”，语意不通，依文直译如下）：主治阴证及长久……借助其甲……都是……鹿……五……产后气虚……孕妇不宜使用。身体虚弱而无热邪的患者，也不宜使用。（引自陈实功/仲淳）
【鉴别与治疗炮制】阳龟的壳圆，底板白色；阴龟的壳长，底板黄色。男性患者用阴龟，女性患者用阳龟。锯去四周边缘，在石上磨净。用灰火炒过，涂酥油炙至黄色使用。也有酒炙、醋炙、猪脂炙、烧成炭使用的。（引自李时珍/濒湖）。凡是入药，必须研磨得极细。
【龟肉】味道甘甜、酸，气温。酿酒服用，治疗风痛引起的拘急痉挛，四肢拘挛，或者年久不愈的瘫痪弛缓，都有疗效。筋骨疼痛……（原文此处插入另一段关于龟肉的描述，逻辑稍显跳跃，按原文顺序翻译）：取一个龟，分为四只脚，每次用一只脚，加入天花粉、枸杞子各一钱二分，雄黄五分，麝香五分，槐花……（原文缺量词，推测为“一钱”），水一碗，煎服。
【龟肉论述】龟肉是治疗痛风的重要药物。朱丹溪在治疗阴火痛风时必定使用它。这是因为该病症多属于血虚，而血脏即对应风木之……（原文缺漏，推测为“脏”或相关五行关系），湿邪……（原文缺漏，语意不全）。
【其他用法】以猪鬃或……（原文缺字，推测为“艾”）叶针刺其鼻子，龟尿即流出。滴入耳中，治疗耳聋。点于舌下，治疗成人中风导致的舌强不语，小儿惊风导致的不能说话。按摩胸背，治疗龟胸、龟背（长期按摩才能痊愈）。染发髭须。岣嵝神书说，龟尿磨瓷器，能使瓷器变软；磨墨书写石头，能渗入数分深。由此可以推断龟尿具有走窍透骨的功效。
[Guibang (Tartar Testudinis Carapax et Plastrum)] Also known as Baiguiban. *Gewu Kao* records: When there is early spring thunder in the sky, there are naturally deceased turtles in the mountains. Upon hearing the sound of thunder, the turtle expels what it holds during hibernation from its mouth. [Note: The original text here is fragmented and likely refers to the turtle emerging from hibernation upon hearing thunder.]
[Properties, Flavor, Meridian Tropism, and Efficacy] Flavor: salty, sweet. Nature: neutral. Turtles infected with dampness possess toxic properties; those not infected are non-toxic. Both flavor and nature are Yin. It enters the Foot-Shaoyin Kidney Meridian. It is incompatible with Shashen (Adenophorae Radix). It tonifies Yin. It treats... [The original text contains significant gaps or typographical errors here ("主阴及久借其甲皆鹿五产下气" is nonsensical in standard medical context]. Based on literal translation: It treats Yin syndromes and prolonged... utilizing its shell... all... deer... five... postpartum Qi deficiency... Pregnant women should avoid using it. Patients who are deficient without heat pathogens should also avoid using it. (Quoted from Zhongchun/Chen Shigong)
[Differentiation and Processing] The shell of a Yang turtle is round with a white plastron; the shell of a Yin turtle is elongated with a yellow plastron. Men should use Yin turtles, and women should use Yang turtles. Saw off the four edges, grind clean on a stone. Stir-fry over ash fire, coat with su (rendered animal fat), and roast until yellow. Alternatively, it may be processed with wine, vinegar, or pig lard, or calcined into charcoal. (Quoted from Binhu/Li Shizhen). For medicinal use, it must be ground extremely fine.
[Guitou (Testudo Carnis)] Flavor: sweet, sour. Nature: warm. Brewed in wine and taken, it treats wind-pain causing spasms and tightness, limb contracture, or chronic flaccid paralysis that does not resolve, showing efficacy. For bone and joint pain... [The text inserts a prescription]: Take one turtle, divide into four feet. Use one foot per dose, add Tianhuafen (Trichosanthis Radix) and Gouqizi (Lycii Fructus) each 1.2 qian, Xionghuang (Realgar) 0.5 qian, Shexiang (Musk) 0.5 qian, Huaihua (Sophorae Flos)... [missing unit, likely 1 qian], one bowl of water, decoct and take.
[Discussion on Guitou] Turtle meat is an essential medicine for treating gout. Zhu Danxi invariably used it for treating gout caused by Yin-fire. This is because such conditions mostly belong to Blood deficiency, and the Blood organ corresponds to Wind-Wood... [text fragment], Dampness... [text fragment incomplete].
[Other Applications] Prick its nose with a hog bristle or... [missing character, likely mugwort leaf] needle, and the urine will flow out. Drip into the ear to treat deafness. Apply under the tongue to treat adult stroke-induced aphasia and pediatric convulsions with muteness. Massage the chest and back to treat "Turtle Chest" and "Turtle Back" (prolonged massage leads to recovery). To dye beard and hair. *Goulou Shenshu* states that grinding porcelain with turtle urine can soften the porcelain, and grinding ink with it allows writing on stone to penetrate several fen deep. From this, we can infer its ability to open orifices and penetrate bones.
