味辛，性平。具有杀虫、明目的功效。用于治疗虚劳咳嗽（劳瘵）及五种疳积，以及痘疹痊愈后眼睑生翳。（李时珍说：獭肝能解毒杀虫，所以在治疗眼疾、疳积、虚劳、疮疡、痔疮的方剂中，常常使用它。沈括在《良方》中记载：江阴人万融患虚劳病，四肢如火烧般灼热，忽冷忽热，烦躁不安，夜里梦见有人抱着一个月亮的光明进入他的腹部，使他心骨都感到寒冷。等到睡醒后，孙元规派人送来药物，服用后病情随即平稳。询问那是什么药，原来是“明月丹”。这才明白之前的梦境是预兆。“明月丹”治疗虚劳传尸虫，用兔屎四十九粒研成粉末，配伍硇砂（如兔屎大小四十九粒）研成粉末，用生蜂蜜制成梧桐子大小的丸药。在农历十五之前，将甘草浸泡在水中一夜，五更天时取甘草汁送服七丸。如果有虫排出，急忙夹入油锅中煎炸杀死；如果三天后没有虫排出，再服用。）獭肝，能泻肝热，所以能明目。獭肉，性凉血，能解热毒，通利大肠。孕妇忌食獭肉（会导致滑胎）。獭脑，外涂可治冻疮。
獭肝，能杀虫，治疗传尸劳。
味甘、咸，性温。能止咳杀虫。治疗传尸鬼疰有神奇功效。（葛洪说：尸疰、鬼疰，使人寒热交替，神情沉默，不知道病痛所在，但全身各处都不舒服，积累数月多年，直至死亡，死后传染他人，甚至灭门。只有将獭肝阴干研末，用水送服二钱，每日三次，以病愈为限度。鹤皋说：獭是阴物，白天潜伏夜间出来活动，所以能治疗鬼疰。）獭肉，味甘、咸，性寒。治疗骨蒸潮热的虚劳，血脉不通，营卫虚弱胀满，以及女子经络不通、血热、大小肠便秘。治疗疫病、温病，以及牛马流行的疾病。不宜多吃，因为会消耗男子的阳气。
The liver of the otter, also known as "Tian Gou" (Sky Dog).
Sweet and sour in flavor, neutral in nature. It tonifies the middle jiao and benefits qi. It is suitable for consumption. It is indicated for pediatric malnutrition with emaciation and can kill roundworms. The meat is suitable to be eaten. Its efficacy is similar to that of rabbit feces.
Rabbit feces, also known as "Ming Yue Sha" (Bright Moon Sand).
Pungent in flavor, neutral in nature. It expels parasites and improves vision. It treats consumptive disease (Lao Zhai) and five types of childhood malnutrition (Wu Gan), as well as corneal opacity occurring after smallpox/variolae recovery. (Li Shizhen stated: [The otter liver] can detoxify and expel parasites; therefore, it is often used in formulas treating eye diseases, malnutrition, consumptive diseases, sores, and hemorrhoids. Shen Kuo in *Liang Fang* recorded: Wan Rong from Jiangyin suffered from consumptive disease, his four limbs felt like burning, he experienced alternating chills and fever, irritability, and dreamed at night that someone held a moon's brightness into his abdomen, making his heart and bones feel cold. Upon waking, Sun Yuanguan sent medicine, which cured him upon ingestion. Inquiring about the medicine, it was revealed to be "Ming Yue Dan" (Bright Moon Pill), leading him to understand his dream. "Ming Yue Dan" treats parasitic consumptive disease using 49 grains of rabbit feces ground into powder, combined with 49 grains of Nao Sha (Ammonium Chloride) of similar size, ground into powder, and formed into pills the size of wutong seeds with raw honey. Before the full moon, soak licorice root in water overnight, take the juice at dawn, and swallow seven pills. If worms are expelled, immediately clamp them into hot oil to fry and kill; if no worms are passed after three days, administer again.) Otter liver clears liver heat, thereby improving vision. Otter meat cools blood, resolves heat toxicity, and promotes bowel movement. Pregnant women should avoid it (as it may cause miscarriage). Otter brain applied topically treats frostbite.
Otter liver expels parasites and treats transmissive consumptive disease (Chuan Shi Lao).
Sweet and salty in flavor, warm in nature. It stops coughing and expels parasites. It has miraculous effects in treating transmissive ghost-related diseases (Chuan Shi Gui Zhu). (Ge Hong stated: Shi Zhu and Gui Zhu cause alternating chills and fever, silence and depression, unknown source of pain, discomfort everywhere, accumulating over months and years until death, then transmitting to others, potentially wiping out a family. Only by drying otter liver in the shade, grinding it into powder, and taking two qian with water, three times daily, until recovery, can it be treated. Hegao stated: The otter is a yin entity, hiding during the day and emerging at night, thus it treats ghost-related diseases.) Otter meat is sweet and salty, cold in nature. It treats bone-steaming heat due to consumptive disease, stagnation of blood vessels, deficiency and fullness of Ying and Wei, obstruction of meridians in women, blood heat, constipation of the large and small intestines. It treats epidemic febrile diseases, warm diseases, and seasonal diseases in cattle and horses. It should not be consumed in excess, as it depletes male yang qi.
