牡鼠粪中两头尖细的，味道苦、咸，性微寒，无毒，归属于水行，进入足阳明胃经和足厥阴肝经。它主治小儿癫痫，以及大腹水肿和伤寒病愈后因劳累导致的复发（劳复），这些病症都是热邪在阳明经所致。其苦寒之性能清除这两条经络的热邪，因此能主治上述病症。此外，还用于治疗男子“阴易”（伤寒病后男女交接导致的热毒转移）引起的腹痛，以及妇人吹乳（乳汁淤积）和乳痈（乳腺炎）。这都是利用它清热、软坚散结、泄下结滞，并能走窜入肝、胃二经的功效。与白芷、山茨菇、山豆根、连翘、金银花、蒲公英、夏枯草、贝母、橘叶、栝蒌根、紫花地丁、牛蒡子等药同用，治疗乳痈和乳岩（乳腺癌）有效。
对于男子阴易及劳复，使用鼠屎汤：取两头尖的鼠屎十四枚，韭菜白根一大把，加水两盏，煎至一盏，温服，以出粘汗为见效。若未出汗可再服一次。对于妇人吹奶，取鼠屎七粒，红枣七枚，去核后将鼠屎包裹在内烧存性，加入少许麝香，用温酒调服，并可用于治疗初起的乳痈。
牡鼠入药，只取雄性。其膏脂可煎制后外敷烫伤或火烧造成的溃烂疮口；生捣碎可治疗跌打损伤；主治小儿疳积（因营养不良或寄生虫引起的慢性消耗性疾病），可熬酒后随饮。用于补益成人骨蒸痨热（结核病等引起的潮热盗汗），可在做羹时食用。胆汁滴眼可使视力明亮，耳聋也可滴用，但老鼠刚死时胆就会消失，所以最为难得。膏脂还可治疗疮疡以及烫伤灼伤。其粪便煎煮可治疗小儿癫痫，以及伤寒劳复、阴阳易等危重病症。
味咸，性寒，无毒。使用时去掉翅膀和足，炒制。

The feces of the male rat that are pointed at both ends taste bitter and salty, are slightly cold in nature, non-toxic, belong to the Water element, and enter the Foot-Yangming Stomach Meridian and Foot-Jueyin Liver Meridian. It is indicated for pediatric epilepsy (Xian Ji), abdominal distension, and recurrence of illness after recovery from Shanghan due to overexertion (Lao Fu), all of which involve heat pathogens in the Yangming meridian. Its bitter and cold properties can clear the heat in these meridians, thus treating these conditions. It also treats abdominal pain caused by "Yin Yi" (a condition where heat toxins are transferred between partners after recovery from febrile disease) in men, and breast engorgement (Chui Ru) and mastitis (Ru Yong) in women. This utilizes its ability to clear heat, soften hardness, dissipate nodules, and drain accumulation, while traversing into the Liver and Stomach organs. When combined with Baizhi (Angelicae Dahuricae Radix), Shancigu (Colchici Cormus), Shandougen (Sophorae Tonkinensis Radix), Lianqiao (Forsythiae Fructus), Jinyinhua (Lonicerae Japonicae Flos), Pugongying (Taraxaci Herba), Xiakucao (Prunellae Spica), Beimu (Fritillariae Cirrhosae Bulbus), Juye (Citri Reticulatae Pericarpium Viride), Gualougen (Trichosanthis Radix), Zihuadiding (Viola Yedoensis Herba), and Niubangzi (Arctii Fructus), it is effective in treating mastitis and breast cancer (Ru Yan).
For Yin Yi and Lao Fu in men, use Shushi Tang: Take fourteen pointed rat feces, a large handful of the white root of Chinese chives (Jiu Bai Gen), add two cups of water, decoct to one cup, and take warm. Efficacy is indicated by the excretion of sticky sweat. If no sweat occurs, administer again. For breast engorgement in women, take seven rat feces and seven red dates, remove the pits, wrap the feces inside the dates, char until carbonized but retaining substance (Cun Xing), add a small amount of Moschus (Shexiang), and mix with warm wine for oral administration. This also treats early-stage mastitis.
Only male rats are used for medicinal purposes. Their fat can be decocted into an ointment and applied externally to burns or scalds with ulceration; raw and crushed, it treats traumatic injuries; it is indicated for pediatric Gan syndrome (malnutrition/parasitic chronic wasting disease in children); it can be decocted in wine and taken immediately. It tonifies adults suffering from bone-steaming consumption (Gu Zheng Lao - tidal fever and night sweats typical of tuberculosis); it can be eaten as part of a soup. Rat bile dropped into the eyes improves vision, and it can be dripped into ears for deafness, but the gallbladder dissolves shortly after the rat dies, making it extremely rare. The fat/oil treats sores and ulcers as well as burns and scalds. Decoction of its feces treats pediatric epilepsy, and critical conditions such as Lao Fu and Yin Yi following Shanghan.
Taste: Salty. Nature: Cold. Toxicity: Non-toxic. Preparation: Remove wings and feet, stir-fry.
Lougu, also known as Tu Gou (Mole Cricket), is instantly effective for treating ten types of edema. Its efficacy varies by location: swelling on the left is treated to resolve on the left, swelling on the right to resolve on the right; upper body swelling is reduced superiorly, lower body swelling recedes inferiorly. Furthermore, it is said that promoting urination and defecation below the waist constitutes the "Lower" method, serving as a key remedy for obstruction of urine and stool; astringing and consolidating above the waist constitutes the "Upper" method, serving as a simple prescription for incontinence. It also treats mouth ulcers and breast toxicity when ground in wine and taken orally; applied topically, it is quite effective for scrofula (Luo Li); it is particularly spiritual in resolving hard bone nodules. Those with deficiency constitution should avoid it due to its urgent/potent nature.
