即蝙蝠屎，名夜明砂
咸平无毒。伏翼 灰，用夜明砂淘净焙用。
《本经》主目瞑痒痛，明目夜视有精光，其屎治面痈肿，皮肤洒洒时痛，腹中血气，破
寒热积聚，除惊悸。
发明 《本经》治目瞑痒痛用伏翼。近世目科惟用夜明砂，鲜有用伏翼者。要皆厥阴肝
经血分药也。其伏翼屎能破结血消积，故目翳盲障，疟魅淋带，瘰 痈疽皆用之。然蝙蝠食
之大能利人，稍虚不可轻用。
即寒号虫矢，又名
苦酸寒小毒。研细酒飞去砂石晒干。生用则破血，炒
用则和血。
发明 ，候时鸟也。晋地有之。春夏羽仪丰盛，冬时裸形昼夜哀鸣，故杨氏《丹铅
录》谓之寒号虫，屎名五灵脂，谓状如凝脂，而受五行之灵气也。其气腥秽，其味苦酸，大
伤胃气。《纲目》言其甘温，恐非正论。虽有治目翳、中脘疼痛之功，惟藜藿庶可应用，终
非膏粱所宜。同蒲黄名失笑散，治一切心胸腹胁少腹诸痛，及产后结血、血崩，目中生翳往
来不定，其性入肝散血最速。但性极膻恶，脾胃虚者，不能胜其气也。
甘平无毒。
发明 斑鸠补肾，故能明目，治虚损益气，食之令人不噎。目科斑鸠丸、锦鸠丸用之，
取气血为引导，以助补肾明目之功也。
平有毒。
发明 方药未有用者。其毛治小儿继病，欲作 病。取毛带之，继病者，母有娠乳儿，
儿病如疟痢，他日相继腹大或瘥或发，他人有娠相近亦能相继也。北人未识此病。
It is the feces of bats, named Yeming Sha (Night-bright Sand).
Salty, neutral, non-toxic. When using Fuyi Hui (Bat Ash), it must be washed clean with Yeming Sha and then roasted for use.
Ben Jing (Divine Farmer's Materia Medica) records that it primarily treats dimness, itching, and pain of the eyes, enhances visual acuity allowing clear night vision, and its feces treat facial carbuncles and swelling, intermittent skin pain, stagnation of blood and Qi in the abdomen, breaks up cold-heat accumulations, and eliminates palpitations due to fright.
Invention: Ben Jing uses Fuyi (Bat) to treat eye dimness, itching, and pain. In modern times, ophthalmologists only use Yeming Sha, rarely using Fuyi. Both are medicines acting on the Blood aspect of the Jueyin Liver Meridian. The feces of Fuyi can break up congealed blood and dissipate accumulations; therefore, it is used for cataracts and blindness, malaria, stranguria and leukorrhea, scrofula, and carbuncles. However, while large consumption of bats benefits humans, those slightly deficient should not use it lightly.
It is the feces of the "Cold Number Bug" (Trogopterus dung), also known as Wulingzhi.
Bitter, sour, cold, slightly toxic. Grind into fine powder, fly with wine to remove sand and stones, and dry in the sun. Raw use breaks blood, while stir-fried use harmonizes blood.
Invention: Wulingzhi comes from a migratory bird found in the Jin region. In spring and summer, its plumage is abundant and majestic; in winter, it appears naked and cries mournfully day and night. Thus, Yang Shi's Danqian Lu calls it the Cold Number Bug. Its feces are named Wulingzhi because they resemble solidified fat and are said to receive the spiritual energy of the Five Elements. Its odor is fishy and foul, and its taste is bitter and sour, severely damaging Stomach Qi. Gangmu states it is sweet and warm, which is likely incorrect. Although it has efficacy in treating eye opacities and epigastric pain, it is suitable only for commoners, not for those accustomed to rich diets. Combined with Puhuang (Polygoni Multiflori Herba), it forms Shixiao San (Laughing Dispersal Powder), treating various pains in the chest, heart, abdomen, hypochondrium, and lower abdomen, as well as postpartum blood stasis, metrorrhagia, and unstable eye opacities. Its nature enters the Liver to disperse blood most rapidly. However, its smell is extremely fishy and repulsive, and those with Spleen-Stomach deficiency cannot tolerate its Qi.
Sweet, neutral, non-toxic.
Invention: Banjiu (Turtledove) tonifies the Kidney, thus enhancing vision, treating deficiency and benefiting Qi. Consuming it prevents dysphagia. Ophthalmic formulas such as Banjiu Wan and Jinjiu Wan use it, taking the Qi and Blood as guides to assist in tonifying the Kidney and improving vision.
Neutral, toxic.
Invention: No prescriptions or medicines currently use it. Its fur treats neonatal tetanus (Jibing), preventing the onset of wind-stroke symptoms. Carrying the fur prevents Jibing. Jibing refers to infants born to pregnant mothers who are breastfeeding; if the infant suffers from illness resembling malaria or dysentery, other infants may subsequently develop abdominal distension, recovering or relapsing later. Other pregnant women nearby may also sequentially contract the disease. People in the North are unfamiliar with this illness.
