雷公云∶凡使要重一斤者方采之，每修事先拭去肉上皮毛爪肠，留翅并肉脚及嘴，然后
酒浸一宿，漉出取黄精自然汁涂之，炙令干方用，每修事重一斤一个，用黄精自然汁五两为
度。
【雄雀】
味道甘、咸，性质热，无毒，归入命门经。主要功效为益气壮阳。其脑髓主治耳聋及冻疮，头部血液主治雀盲（夜盲症）。粪便名为白丁香，主治痈疽疖肿，点涂于目内胬肉血膜，消除症瘕伏梁，溃烂癖积块。
按语：雀肉味咸性热，适宜入命门以补火。然而若相火长期过亢，肾水必然衰败，不宜过量服用，以免损伤肾脏，孕妇尤其忌食。脑血及白丁香的功用，皆由其咸热之性所致。
【雀卵】
味道酸、温，无毒。主要功效为下气，治疗男子阳痿不起，增强性功能使其勃起发热，增加精液从而生育子女，脑髓主治耳聋，头部血液主治雀盲。雄雀屎可用于治疗齿痛、目痛，治愈痈疽疖肿，治疗女子带下病、小便不利，消除疝气瘕块。五月采集效果最佳。注释说，两头尖的是雄雀屎。
雷公云：处理雀卵时，不要用雀儿的粪便，那些雀儿口部黄色且未交配过的，其粪便连着苏草。如果底部坐落处尖端朝上，就是雌雀，两头圆润的是雄雀。女性使用雄雀，男性使用雌雀。凡是采集时先去掉两边有附子生长的部分，通用处理后，然后在钵中研磨成粉，用甘草汤浸泡一夜，倒去上层清液，待甘草水吸尽后，焙干备用。
【伏翼】
味道咸，性质微热，有毒，不记载归经。主要功效为驱逐五种淋证，通利水道，去除眼翳明目，使人喜悦快乐，媚好忘忧，久服可延年益寿。粪便名为夜明砂，能破除腹中血气及寒热积聚，消除惊悸。血液可用于点眼，形体重量达一斤，颜色白如雪的为佳。
按语：伏翼原名蝙蝠，因为它白天潜伏夜晚飞翔，所以称为伏翼。它能伏藏元气，冬季不进食，因此多长寿，人服用它，确实具有延年的功效。
雷公云：凡是采集要选重量达一斤的才进行采收，每次炮制前先擦去肉上的皮毛爪肠，保留翅膀以及肉脚和嘴，然后用酒浸泡一夜，滤出取黄精自然汁涂抹，炙烤至干燥方可使用。每次炮制重量为一斤的一个，使用黄精自然汁五两为标准。
[Male Sparrow]
The flavor is sweet and salty, the nature is hot, it is non-toxic, and enters the Mingmen meridian. It primarily tonifies Qi and strengthens Yang. Its brain treats deafness and frostbite; its head blood treats sparrow blindness (nyctalopia). The feces are named Bai Ding Xiang (White Larkspur), which treats carbuncles and boils, can be applied to pterygium and blood membranes in the eye, eliminates Zheng Jia Fu Liang (masses and fixed lumps), and resolves Pi Ji Kuai (accumulated masses).
Note: The salty and hot nature of the sparrow makes it suitable for entering the Mingmen to supplement fire. However, if Ministerial Fire is excessively heated for a long time, Kidney Water will inevitably decline. It should not be taken in excess to avoid damaging the Kidneys; pregnant women are particularly advised to avoid consuming it. The efficacy of the brain blood and Bai Ding Xiang is derived from their salty and hot properties.
[Sparrow Egg]
The flavor is sour and warm, it is non-toxic. It primarily directs Qi downward, treats male impotence (Yin Wei) where erection does not occur, enhances sexual function to induce heat and erection, increases semen to facilitate conception, the brain treats deafness, and the head blood treats sparrow blindness. Male sparrow feces are used to treat toothache and eye pain, cure carbuncles and boils, treat leukorrhea in women, dysuria, and eliminate Shan Jia (hernia and masses). Collected in the fifth lunar month, it is considered optimal. The annotation states that those with two pointed ends are male sparrow feces.
Lei Gong said: When processing sparrow eggs, do not use sparrow feces. Those sparrows with yellow mouths that have not yet mated have feces attached to Su grass. If the base sits with the point upward, it is female; those with two rounded ends are male. Females should use male sparrow [eggs/feces context implies specific preparation], males should use female. When harvesting, first remove any parts adjacent to growing Aconite (Fuzi), then grind into powder in a mortar. Soak overnight in Gancao Tang (Licorice Decoction), discard the upper clear liquid, allow the Licorice water to be fully absorbed, then bake dry for use.
[Fu Yi / Bat]
The flavor is salty, the nature is slightly hot, it is toxic, and its meridian tropism is not recorded. It primarily expels the five types of Lin syndrome (dysuria), promotes urination, removes nebulae to brighten the eyes, induces joy and happiness, alleviates sorrow, and prolongs life when taken for a long time. The feces are named Ye Ming Sha (Night-Bright Sand), which breaks up blood and Qi stagnation in the abdomen, as well as cold-heat accumulations, and eliminates palpitations and fright. The blood can be applied to the eyes; specimens weighing one jin with color white as snow are considered superior.
Note: Fu Yi was originally named Bian Fu (Bat) because it hides during the day and flies at night. It can "hide" Qi (store essence), does not eat in winter, and thus lives long. Human consumption of it indeed contributes to longevity.
Lei Gong said: Only harvest those weighing one jin. Before processing, wipe away all skin, hair, claws, and intestines, retaining only the wings, flesh, feet, and beak. Then soak in wine overnight, drain, and coat with Huang Jing Zi Ran Zhi (natural juice of Polygonatum sibiricum). Roast until dry before use. For each batch weighing one jin (one specimen), use five liang of natural Huang Jing juice as the standard amount.
