发明 山獭禀南奥纯阳之气，故其性最淫。专主阳虚阴痿精寒，山中有此，凡牝兽皆避
去，獭无偶则抱木而枯。 女春时入山，獭闻妇人气，跃来抱合牢不可脱，因扼杀而取之也

咸大热无毒。以汉椒、樟脑同收则不坏。
发明 《和剂局方》治诸虚损有腽肭脐丸。滋阴丸药中用之，精不足者，补之以味也。
今人多于房术方中用之，亦可同糯米法曲酿酒服。但功专补阳，阴虚切忌。此物牝者最多，
而牡者绝少。海州人捕得牝者，以家狗外肾用筋缝上，熨贴，如生成无二。然牝户与谷道连
合为一，虽用生筋缝熨，其孔较牡者大而且长，以此辨之最为有据。
甘温无毒。取胆法，用活鼠系定，热汤浸死，破喉取胆，真红色者是也。误食鼠

发明：山獭禀受南方幽深之地纯阳之气，因此其本性最为淫欲旺盛。专门主治阳虚导致的阴痿、精液寒冷。山中若有此物，所有雌性野兽都会避开它；山獭如果没有配偶，就会抱着树木枯死。女性在春季进山时，山獭闻到妇女的气息，就会跳跃过来紧紧抱住交合，牢固得无法挣脱，因此人们扼杀它来取其生殖器。
一名海狗肾。
咸味，大热，无毒。如果用汉椒（花椒）、樟脑一同收藏，就不会腐烂变质。
发明：《和剂局方》中治疗各种虚损的方剂里有腽肭脐丸。在滋阴的丸药中使用它，是因为“精气不足的人，要用厚味的药物来补益”。现在人多在房中术的方子中使用它，也可以同糯米、酒曲一起酿酒服用。但它的功效专于补阳，阴虚者切忌使用。这种动物雌性最多，而雄性极少。海州人捕获到雌性后，用家狗的睾丸用筋缝合上去，熨烫贴合，看起来如同天然生成一般没有二致。然而雌性的产门与肛门连合为一，即使是用生筋缝合熨贴，其孔洞比雄性的要大而且长，以此作为辨别依据是最有根据的。
甘温无毒。取胆的方法是，用活老鼠绑住固定，用热水浸泡至死，剖开喉咙取出胆囊，真正红色的才是真品。误食被老鼠啃食剩下的东西，会让人发生疮疡，这是因为贪欲之火蕴积、馋涎所致。
发明：癸水（肾水）的位置对应地支中的子，气机通于肾脏，它的眼睛夜间能视物，精华储存在胆囊中。所以胆囊能治疗耳聋、目盲。鼠睛能明目，鼠骨能生齿，都是补肾有效的验证。《肘后方》治疗三十年的老聋或突发耳聋，不过三次就能痊愈。让人侧卧，将胆汁滴入耳中，用完一枚胆的量，片刻之后汁液会从耳下流出，起初会觉得听力更差，十日后才会好转。用生鼠血蘸青盐擦牙齿也有效。刚出生的小鼠用香油浸泡至腐化，取汁涂抹治疗火烫伤效果显著。少量的水能制约过盛的火邪，如果老鼠长了毛就不能消融了。牡鼠的粪便俗名叫两头尖，检验其形状笔直才是牡鼠的粪便，入足厥阴肝经和足少阴肾经。所以煮服可以治疗伤寒、劳复（病愈后因劳累复发）、阴阳易（男女交接后互相传染的病证）、腹痛。研成粉末服用可以治疗乳痈（急性乳腺炎）。烧成灰保留药性敷贴可以治疗跌打损伤、疔疮肿毒。所主治的都是厥阴血分的病证。另外被狗咬伤，先洗去牙垢恶血，用炒过的鼠粪研末，黑糖调匀涂抹即可痊愈。
Sweet, hot, non-toxic.
Invention: The mountain otter (Shanta) inherits the pure yang qi of the deep south; therefore, its nature is extremely lustful. It specifically treats yang deficiency leading to impotence and cold semen. In the mountains, where this animal exists, all female beasts avoid it. If a male otter has no mate, it will embrace a tree until it withers and dies. When women enter the mountains in spring, the otter smells the scent of women, leaps over to embrace them for copulation, holding on so firmly that it cannot be detached; thus, people strangle it to obtain its genitalia.
Also known as Sea Dog Kidney (Wanaqi).
Salty, very hot, non-toxic. If stored together with Sichuan pepper (Hanjiao) and camphor (Zhangnao), it will not spoil.
Invention: The *Heji Jufang* (Formulas of the Bureau of Taiyi) contains Wanaqi Wan for treating various deficiencies and damages. It is used in yin-nourishing pills because "for those whose essence is insufficient, supplementation should be done with substances of strong flavor." Nowadays, people often use it in sexual enhancement formulas; it can also be fermented into wine with glutinous rice and yeast. However, its efficacy is specialized in tonifying yang, and it is strictly contraindicated for those with yin deficiency. This species is mostly female, while males are extremely rare. People in Haizhou, upon catching a female, sew a domestic dog's testicle onto it using tendons, ironing and shaping it so that it looks indistinguishable from a natural specimen. However, the female's vulva is connected to the anus; even when sewn with raw tendons and shaped, the opening is larger and longer than that of the male. This serves as the most reliable method for differentiation.
Sweet, warm, non-toxic. The method for extracting the gallbladder is to tie a live mouse securely, drown it in hot water, cut open the throat, and extract the gallbladder. The genuine one is bright red. Accidentally consuming leftovers eaten by mice can cause sores, due to the accumulation of desire-fire and saliva.
Invention: Gui Water (Kidney Water) corresponds to the Earthly Branch Zi, and its qi connects to the Kidneys. Its eyes see clearly at night, and its essence resides in the gallbladder. Therefore, the gallbladder can treat deafness and blindness. Mouse eyes brighten vision, and mouse bones promote tooth growth; these are all proofs of benefiting the kidneys. The *Zhouhou Fang* treats thirty-year chronic deafness or sudden deafness, which heals after no more than three applications. Have the patient lie on their side, drip gallbladder juice into the ear until one whole gallbladder is used up. Within moments, the fluid drains out from below the ear. Initially, hearing may seem worse, but it improves after ten days. Applying fresh mouse blood mixed with green salt to brush teeth is also effective. Immersing newborn mice in sesame oil until they decompose, then applying the liquid to burns yields good results. A small amount of water can control excessive fire; however, if the mouse has grown fur, it cannot be dissolved. The feces of male mice are commonly called "Two-Ended Point" (Liangtoujian); only those that are straight are confirmed as male mouse feces. They enter the Foot-Jueyin Liver Meridian and Foot-Shaoyin Kidney Meridian. Thus, decocting and taking them orally treats Cold Damage, relapse due to overexertion (Laofu), exchange of yin and yang (Yinyangyi), and abdominal pain. Taking them as a powder treats breast abscess (Ruyong). Burning them to ash while retaining their medicinal properties and applying externally treats traumatic injuries and carbuncles. These indications all pertain to diseases of the Jueyin blood level. Additionally, for dog bites, first wash away tooth debris and bad blood, then apply a paste made from stir-fried and powdered mouse feces mixed with brown sugar, which leads to recovery.
