〔时珍曰〕方用或炮、或烧，或酥炙、醋炙、童便炙，或油煎、土炒、蛤粉炒，当各随
本方，未有生用者。仍以尾甲乃力胜。
〔时珍曰〕古方用酥炙或酒炙。惟治传尸劳瘵天灵盖丸，以石蜥蜴连肠肚，以醋炙四十
九遍用之，亦一异也。
〔 曰〕其毒在眼。须去眼及甲上、尾上、腹上肉毛，以酒浸透，隔两重纸缓焙令干，
以瓷器盛，悬屋东角上一夜用之，力可十倍，勿伤尾也。〔日华曰〕凡用去头、足，洗去鳞

安蜕于中，一宿取出，醋浸炙干用。〔时珍曰〕今人用蛇蜕，先以皂荚水洗净缠竹上，或酒、

〔弘景曰〕炙黄用。〔 曰〕凡使勿用沙鱼骨，其形真似。但以上文顺者是真，横者是

以龟甲锯去四边，石上磨净，灰火炮过，涂酥炙黄用。亦有酒炙、醋炙、猪脂炙、烧灰

〔李 曰〕经卜者更妙。以酥或酒炙黄用。
〔时珍曰〕此龟古方无用者。近世滋补方往往用之，大抵与龟甲同功。刘氏先天丸用之

〔李时珍说〕方剂中使用时，有的炮制、有的烧制，有的用酥油炙、醋炙、童便炙，有的用油煎、土炒、蛤粉炒，应当各自遵循原方的规定，没有生用的。仍然以尾部的甲片药效最强。
〔李时珍说〕古方中使用酥炙或酒炙的方法。只有治疗传尸劳瘵（一种慢性消耗性传染病）的天灵盖丸中，使用石蜥蜴连肠肚一起，用醋炙四十九遍后使用，这也是一种特殊用法。
〔无名氏曰〕其毒性在眼睛处。必须去掉眼睛以及甲上、尾上、腹上的肉毛，用酒浸透，隔两层纸缓慢焙干，用瓷器盛装，悬挂在房屋东角一夜后使用，药效可增强十倍，注意不要损伤尾部。〔日华子曰〕凡是用绿毛龟，要去掉头、足，洗去鳞鬣内的污物。
〔无名氏曰〕凡是用蛇蜕，不要用青色、黄色、苍色的，只用白色如银的。先在地下挖一个坑，深一尺二寸，将蛇蜕放入其中，过一夜取出，用醋浸后炙干使用。〔李时珍说〕现在人用蛇蜕，先用皂荚水洗净缠绕在竹子上，或用酒、或用……
〔苏颂说〕头尾各有一尺长，有大毒，不可用。只用中段干燥的，用酒浸，去掉皮、骨，炙过后收存则无毒。不炙，头尾……炭火……
〔陶弘景说〕炙黄后使用。〔无名氏曰〕凡是用沙鱼骨（鲨鱼骨），不要用沙子做的假骨，形状非常相似。但以上文顺纹的是真品，横纹的是假货。用血卤水浸泡，并煮一个时辰后捞出。挖一个坑烧红，将鱼骨放入在内，经过一夜取出入药，药效加倍。
用龟甲锯去四边，在石上磨净，用灰火炮制过，涂酥油炙黄后使用。也有用酒炙、醋炙、猪脂炙、烧成灰使用的。
〔李时珍说〕这种龟古方中没有使用的。近世滋补方剂中往往使用它，大致功效与龟甲相同。刘氏先天丸中使用它，其方法是取九枚龟，将两条活鲤鱼放入釜中，加入水，上面覆盖米筛，将龟放在筛上蒸熟，取出肉晒干。其甲仍然……
[Li Shizhen said] In prescriptions, they may be processed by calcination, burning, frying with butter, frying with vinegar, or frying with children's urine; or fried in oil, stir-fried with soil, or stir-fried with clam powder. One should follow the specific prescription, and there is no use of raw material. The scutes from the tail are considered to have the strongest efficacy.
[Li Shizhen said] Ancient prescriptions used methods such as frying with butter or wine. Only in the Tianlinggai Pill (Heavenly Skull Cap Pill) for treating Chuan Shi Lao Zhai (a chronic consumptive infectious disease), Stone Lizard (Shexi, 石蜥) including intestines and stomach is used, fried with vinegar forty-nine times, which is a unique method.
[Anonymous] Its toxicity lies in the eyes. One must remove the eyes and the flesh and hair on the shell, tail, and abdomen. Soak it thoroughly in wine, slowly dry it by baking through two layers of paper, store it in a porcelain vessel, hang it in the east corner of the house for one night before use, which can increase its efficacy tenfold. Do not damage the tail. [Ri Hua said] When using Green-haired Turtle (Lumao Gui, 绿毛龟), remove the head and feet, and wash away the dirt within the scales and bristles.
[Anonymous] When using Snake Slough (Shetui, 蛇蜕), do not use those that are green, yellow, or grayish-blue; only use those that are white like silver. First, dig a pit in the ground one chi and two cun deep, place the slough inside, leave it overnight, take it out, soak in vinegar, and fry until dry for use. [Li Shizhen said] Nowadays, people clean snake slough first with soap pod water, wrap it around bamboo, and then either use wine or...
[Su Song said] The head and tail, each about one chi long, contain severe toxicity and should not be used. Only use the dried middle section. Soak in wine, remove skin and bones, and process by frying before storage to eliminate toxicity. Not fried, head and tail... charcoal fire...
[Tao Hongjing said] Fry until yellow for use. [Anonymous] When using Shark Bone (Shayu Gu, 鲨鱼骨), do not use bone made of sand, as the shape is very similar. However, those with longitudinal grain are genuine, while those with transverse grain are fake. Soak in saline water, boil for one fu shi (approx. 2 hours), then drain. Dig a pit, heat it red-hot, place the fish bone inside, leave overnight, then take out for medicinal use, which doubles its efficacy.
Saw off the four edges of the Tortoise Shell (Guijia, 龟甲), grind it clean on a stone, process by firing with ash, coat with butter, and fry until yellow for use. Some are processed by frying with wine, vinegar, or pig lard, or burned to ash for use.
[Li Gao said] It is even better if processed by diviners. Fry with butter or wine until yellow for use.
[Li Shizhen said] This type of turtle was not used in ancient prescriptions. In recent times, it is often used in nourishing prescriptions, with effects generally similar to Tortoise Shell (Guijia, 龟甲). Liu's Xiantian Pill uses it; the method involves taking nine turtles, placing two live carp in a pot with water, covering with a rice sieve, placing the turtles on the sieve, steaming until cooked, taking out the meat, and drying it. The shells are still...
