陶隐居说：燕子有两种，一种是胡燕，一种是越燕。胸部紫色、体型轻小的是越燕，不用于入药；胸部有黑斑、叫声大的是胡燕。俗称为夏候，它们筑巢喜欢把巢做得很长，有人说能容纳一匹绢的长度，据说能让家庭富裕。燕巢也可以入药，与燕屎功效相同，多用来煮水洗澡，治疗小儿惊邪。巢口朝北以及尾部弯曲且颜色白色的，都是几百岁的老燕，食用可以延年益寿。凡是燕肉不可食用，吃了会让人在水中遭遇蛟龙吞食。也不宜杀害燕子。唐本注说：《别录》记载，胡燕的卵，主治水肿浮满。燕肉，可去除痔疮中的虫。越燕的屎也能治疗痔疮，杀虫，去除眼部的翳障。现在考察陈藏器的草类药物记载：燕屎有毒。主治疟疾。取方寸匕大小的量，让患者在发病当天的清晨，与一升酒混合搅匀。患者双手捧碗在鼻子下方承接气味，千万不要入口，因为对人有毒。另外，主治蛊毒。取燕屎三合，炒至香味出来，独头蒜十枚，去皮，一起捣碎制成丸药。服用三丸，大小如梧桐子，蛊毒会随着痢疾排出体外。臣禹锡等人按照孟诜的说法：石燕，生长在乳穴石洞中的，冬季采集，可以食用。其他的不能吃，只能治病，食用方法如同常规饮食，取二十枚，投入一斗酒中浸泡，三天后取出饮用。每次服用一两盏，根据体质适量，非常补益气力。日华子说：石燕，性暖，无毒。壮阳，温暖腰膝，添精补髓，益气，滋润皮肤，缩小便，抵御风寒、山岚瘴气和瘟疫之气。

《外台秘要》治疗蠼 尿疮（一种绕身一周即致命的恶疮），用燕巢中的泥土、猪脂、醋调和后敷贴。《肘后方》：治疗突然发作的大腹水病。取胡燕卵中的蛋黄，一次性吞服十枚。葛氏方：突然患上浸淫疮，有渗出液，多发于心部，如果不早治疗，环绕全身就会致死。用胡燕巢中的泥土，用水调和后敷贴。另一个方子：如果是石淋（尿路结石），取燕屎粉末，用冷水送服五钱匕，早晨服用直到吃饭时应该能排出结石和水。贾相公牛经：牛在非正常时间吃了混杂的虫子，导致腹胀满。取燕子粪一合，与水浆二升混合，灌服，有效。
Pungent in flavor, neutral in nature, and toxic. It primarily treats gu poison (parasitic poisoning) and gui zhu (a chronic wasting disease caused by evil qi), expels inauspicious evil qi, breaks the five types of long (urinary retention or difficulty in urination), and promotes diuresis. It grows in high mountains and flat valleys.
Tao Hongjing stated: There are two types of swallows: Hu swallow and Yue swallow. The Yue swallow, characterized by a purple chest and small size, is not used for medicinal purposes; the Hu swallow, characterized by black spots on the chest and loud calls, is used. Commonly called "Xiahou," they prefer to build long nests, with some said to be long enough to hold a bolt of silk, which is believed to bring wealth to the household. Swallow nests can also be used medicinally, similar to swallow droppings, often boiled for bathing to treat pediatric fright-evil. Nests facing north or those with curved tails and white colors belong to hundreds-of-years-old swallows; consuming them prolongs life. Swallow meat must not be eaten, as it is believed to cause one to be swallowed by dragons in water. Killing swallows is also inadvisable. The Tang Ben Zhu notes: *Bie Lu* records that Hu swallow eggs treat edema and floating swelling. Swallow meat removes worms from hemorrhoids. Yue swallow droppings also treat hemorrhoids, kill parasites, and remove eye nebulae. According to Chen Cangqi's herbal records: Swallow droppings are toxic. They treat malaria. Take a measure of one square inch, and on the morning of the patient's fever day, mix it with one sheng of wine and stir well. The patient should hold the bowl under their nose to inhale the fumes, strictly avoiding ingestion due to toxicity. Additionally, it treats gu poison. Take three he of swallow droppings, roast until fragrant, combine with ten peeled single-clove garlic bulbs, pound into pills. Take three pills, sized like wu tong seeds; the gu poison will be expelled via diarrhea. Ministers Yuxi et al., following Meng Shen, state: Stone swallows found in limestone caves are harvested in winter and are edible. Others are inedible but medicinal; consume twenty pieces soaked in one dou of wine for three days, then drink. Take one or two cups per dose according to tolerance, which greatly boosts qi and strength. Ri Hua Zi states: Stone swallow is warm and non-toxic. It strengthens yang, warms the waist and knees, replenishes essence and marrow, tonifies qi, moistens the skin, reduces urination, and resists wind-cold, mountain miasma, and epidemic qi.
The Tu Jing provides detailed illustrations under the entry for Sparrow Eggs.
*Waitai Miyao* treats qu niao chuang (a fatal ulcer encircling the body) by applying a mixture of soil from swallow nests, lard, and vinegar. *Zhouhou Fang* treats sudden onset of massive abdominal ascites by swallowing ten Hu swallow egg yolks at once. Ge Shi's Formula treats sudden impetigo with exudate originating from the heart; if untreated early, it spreads around the body and causes death. Apply soil from Hu swallow nests mixed with water. Another formula for stone lin (urinary calculi): take swallow droppings powder, administer with cold water, five qian bi in the morning; stones should be passed by mealtime. Jia Xiang Gong Niu Jing states: For cattle suffering from abdominal distension after ingesting mixed worms at irregular times, take one he of swallow dung, mix with two sheng of water-gruel, and drench the animal; this is effective.
