〔谨
案〕龟取以酿酒，主大风缓
急，四肢拘挛，或久瘫缓不收摄，皆瘥。
味咸，性平，无毒。主治眼部障翳疼痛、青盲（视力减退或失明）。长期服用可益精明目，使身体轻盈。产于南海。
民间传说这是紫贝，其实略有不同，但也很难得。又有人说它是鳆鱼（鲍鱼）的甲壳，附着在石头上生长，大的如手掌大小，色泽明亮闪耀五色，内部也含有珍珠。现在人们都用紫贝用水浸泡后熨贴眼睛，颇能明目。这种药材，原本也附见于决明条下，因为甲壳既属异类，现在列为副品。
【谨案】此物，是鳆鱼的甲壳，附着石头生长，形状像蛤蜊，只有一片无对、有七个孔的为优良。现在民间使用的紫贝完全不同，不属于此类。
味苦，无毒。主治除湿痹气滞，身体沉重，四肢关节不能动摇。产于山北阴湿的土壤中，二月和八月采收。
这就是山中的龟，不进入水中的，形体大小不定，方药中不常用。龟类虽然多，入药的只有两种罢了。又有种龟，小且狭长尾巴，据说能治疗蛇毒，因为它吃蛇的缘故，用它来占卜则吉凶相反。佩戴秦龟的前骨，让人进入山林不迷路。广州有一种龟，其血液很能治疗俚人（南方少数民族）的毒箭伤。
【谨案】龟腹破裂，见到蛇就会吞食它，荆楚之间，称之为呷蛇龟。秦龟，就是这种龟，没有别的区别。
味咸、甘，性平，有毒。主治漏下赤白（妇科带下病），破除症瘕疟疾，五痔，阴蚀，湿痹，四肢沉重虚弱，小儿囟门不合，治疗头部疮疡难以干燥，女子阴疮及惊恚气，心腹痛不能久立，骨中寒热，伤寒劳复，或者肌体寒热欲死，做成汤剂良好。长期服用可使身体轻盈不饥饿，益气增智，也能使人食欲增加。一名神屋，产于南海池泽及湖水中，随时可采，不要让其中湿，中湿就有毒。
畏沙参、蜚蠊（蟑螂）。这种用水中的神龟，长一尺二寸的为佳，厌恶它可以用来占卜，壳可以用来供药用，也进入仙方，使用时应当炙烤。生龟尿，很能治疗久咳，也能截断疟疾。肉，做羹汤，大补且有神灵之效，不可轻易杀害。书籍记载很多，这里不详细说了。
Salty, neutral, non-toxic. Primarily treats eye obstructions, nebulae, and pain, as well as Qingmang (blindness or severe visual impairment). Long-term consumption benefits essence, lightens the body. Grows in the South Sea.
Folklore claims it is Zi Bei (Purple Shell), which is slightly different but also rare. It is also said to be the shell of the Bao Yu (Abalone/Fissurella), growing attached to rocks, large ones like a hand, shining with five colors, and containing pearls inside. Nowadays, people soak Zi Bei in water and apply it to the eyes for熨 (hot compress), which can improve vision. This substance was originally listed under the Jue Ming (Cassia Seed) entry; since its shell belongs to a different category, it is now listed as a secondary item.
[Note] This substance is the shell of the Bao Yu (Abalone/Fissurella), growing attached to rocks, shaped like a clam, with only one piece without a pair, and those with seven pores are superior. The Zi Bei (Purple Shell) used by common people today is completely different and does not belong to this category.
Bitter, non-toxic. Primarily treats damp-bi qi stagnation, heaviness of the body, and immobility of the four limbs and joints. Grows in the yin soil of mountains, harvested in February and August.
This is the mountain turtle that does not enter water, with variable size, rarely used in prescriptions. Although there are many types of turtles, only two are used in medicine. There is another type of turtle, small with a narrow long tail, said to treat snake venom because it eats snakes; using it for divination yields opposite auspicious/inauspicious results. Carrying the anterior bone of the Qin Gui (Qin Turtle) prevents getting lost in mountains. In Guangzhou, there is a [missing character] turtle, whose blood effectively treats arrow wounds from the Li people (southern ethnic minorities).
[Note] When a turtle's belly is broken, it swallows snakes upon seeing them. In Jingchu, it is called Xi She Gui (Snake-Swallowing Turtle). Qin Gui is exactly this turtle, with no other distinction.
Salty and sweet, neutral, toxic. Primarily treats leukorrhea (red and white discharge), breaks zheng jia (masses) and malaria, five types of hemorrhoids, genital erosion, damp-bi, heaviness and weakness of the four limbs, unclosed fontanelle in infants, difficult-to-dry head sores, female genital sores, shock and anger qi, abdominal pain preventing prolonged standing, cold-heat in bones, relapse of Shanghan (Cold Damage) due to overexertion, or severe cold-heat in muscles and body nearing death; making it into a decoction is excellent. Long-term consumption lightens the body, reduces hunger, tonifies qi, enhances wisdom, and promotes appetite. Also known as Shen Wu, grows in ponds, marshes, and lakes in the South Sea, harvestable anytime. Avoid moisture; if it becomes moist, it becomes toxic.
Incompatible with Shashen (Adenophora Root) and Feilian (Cockroach). For aquatic divine turtles, those one chi two cun long are best. They are avoided for divination, their shells are used for medicine, and they enter immortal formulas, requiring roasting when used. Urine from raw turtles effectively treats chronic cough and can stop malaria. Meat, made into soup, provides great tonification and spiritual efficacy; do not kill lightly. Books record much about it, not detailed here.
[Note] Turtles taken to brew wine primarily treat Feng Zheng (Wind Stroke) with flaccidity/spasticity, limb contractures, or chronic paralysis with loss of control, all of which resolve.
