【气味与主治】
味甘、酸，性寒。治疗赤白久热痢疾。取一升蚯蚓泥炒至烟尽，加入半升水汁，过滤后饮用。治疗一切丹毒，用水调和蚯蚓泥外敷。治疗反胃吐食，用地龙粪一两、木香三钱、大黄七钱，研为细末。每次服用五钱，用无根水调服一二剂，效果神奇。忌食煎炸、爆炒、酒、醋、花椒、生姜及热性食物。治疗足部烂疮，取韭菜地里的蚯蚓粪干燥后研细，加入轻粉，用清油调和后外敷。治疗下部杨梅结毒（梅毒硬下疳或树胶肿），取韭菜地里的蚯蚓泥和硫黄，等分研匀，用泥封固做成团块，煨烧过后取出研细，用生桐油调和涂抹。
【论述】
蚯蚓在孟夏（农历四月）开始出土，仲冬（农历十一月）蛰伏结团。下雨时先出土，天晴时夜间鸣叫。似乎具有成形的阴质，而化生气的阳能，因此能得气之先机。郭璞称赞它为“土精”。土本来就是阴阳合和而成的，不能说是它专属阴寒。它所食用的枯壤，已经脱化了寒水之气，而它转化排出的粪便，就是脱化之后所剩余的物质。土本主湿，反而能行湿，是因为阴阳相互依附。再看它脱化排出的过程，乘着转化的气机，来行湿并清热，功效难道不是更快捷吗？（《内经》说“三阳结”会导致目疾。）蚯蚓又名六一泥。大概是指六种药材（矾石、黄矾、蚯蚓粪、咸土、盐各一两，黄泥一斤）同为细末，捣和成泥，用来固济炼药的盒子罢了。如果单独把这个名字归于蚯蚓粪，似乎不完全正确。
虚寒滑利者，不宜使用。（仲淳评注）
【孩儿茶】
又名孩儿茶。产于南洋爪哇、暹罗等国。现在云南老挝暮云场地方也有制造。取细茶末放入竹筒中，两头紧紧塞住，埋在污泥沟中，日久取出，捣汁熬制而成。块小且润泽的为上品，块大而焦枯的次之。（濒湖评注）按此药内治用法极少。味苦涩，气平寒。清上膈热，化痰生津。涂金疮及一切诸疮，生肌定痛，止血收湿。得污泥中至阴之气，而能凉血清热。苦能燥湿，涩能收敛，所以主要主治收湿气。（仲淳评注）同薄荷叶、细茶研为细末，蜜丸，饭后含化三五粒，能消痰。牙疳口疮，孩儿茶、硼砂等分为末，搽之。下疳阴疮，孩儿茶一钱，真珠一分，片脑半分，研为细末外敷。各种肿毒，孩儿茶、蝉蜕各等分，研为细末，用雄猪胆汁调和外敷，有效。脱肛气热，孩儿茶二分，雄胆五分，片脑一分，研为细末，用人乳调和搽于肛门上，热气自下而肛门收缩。也治疗痔疮。
[Flavor, Properties, and Indications]
Sweet, sour, and cold in nature. Treats chronic dysentery with red and white discharge due to heat. Take one sheng of earthworm mud (Qiu Yin Ni), stir-fry until smoke disappears, add half a sheng of water juice, filter, and drink. For all types of erysipelas (Dan Du), mix earthworm mud with water and apply externally. For regurgitation and vomiting of food, use one liang of earthworm feces (Di Long Fen), three qian of Costus root (Mu Xiang), and seven qian of Rhubarb (Da Huang), grind into powder. Take five qian each time, mixed with unrooted water for one or two doses; the effect is miraculous. Avoid fried, roasted foods, alcohol, vinegar, Sichuan pepper, ginger, and hot-natured foods. For ulcerated sores on the feet, take dried earthworm feces from leek fields, grind finely, add Calomel (Qing Fen), and apply externally mixed with refined sesame oil (Qing You). For chancres or gummas of syphilis (Yang Mei Jie Du) in the lower body, take earthworm mud from leek fields and Sulfur (Liu Huang) in equal parts, grind uniformly, seal with mud to form a ball, roast over coals, take out, grind finely, and apply externally mixed with raw Tung oil (Sheng Tong You).
[Discussion]
Earthworms emerge at the beginning of Mengxia (the fourth lunar month) and hibernate in Zhongdong (the eleventh lunar month). They emerge first when it rains and cry at night when it is clear. It seems to possess formed Yin substance while transforming Qi through Yang, thus obtaining the initiative of Qi. Guo Pu praised it as the "Spirit of Earth" (Tu Jing). Earth is inherently formed by the harmony of Yin and Yang, so it cannot be said to belong exclusively to Yin-cold. The withered soil it consumes has already transformed away the Qi of Cold-Water, and its excreted feces are merely the residue of this transformation. Earth naturally governs dampness, yet it can also move dampness because Yin and Yang adhere to each other. Furthermore, looking at the process of excretion driven by transformative Qi, it moves dampness and clears heat; is its efficacy not even more rapid? (The *Classic* states that "binding of the Three Yang" leads to eye disorders.) Earthworm mud is also known as Liu Yi Ni (Six-One Mud). This likely refers to six ingredients (Alum, Yellow Alum, Earthworm Feces, Salty Soil, Salt, each one liang, and Yellow Mud one jin) ground together and mixed into a paste, used to seal and secure crucibles for refining medicines. If this name is attributed solely to earthworm feces, it seems incomplete.
It is not suitable for those with deficiency-cold and loose stools. (Comment by Zhong Chun)
[Child's Tea / Hai Er Cha]
Also known as Hai Er Cha. Originates from Nanyang countries such as Java and Siam. Currently, it is produced in the Muyun Chang area of Laos, Yunnan. Fine tea powder is placed into bamboo tubes, both ends tightly plugged, buried in muddy ditches, and after a long period, taken out, juiced, and boiled into cakes. Small and moist cakes are superior; large and scorched/dry cakes are inferior. (Comment by Bin Hu) According to this, internal use is very rare. Bitter and astringent, neutral and cold in nature. Clears heat in the upper diaphragm, transforms phlegm, and generates fluids. Applied to metal wounds and all kinds of sores, it promotes tissue regeneration, relieves pain, stops bleeding, and absorbs dampness. By acquiring the extreme Yin Qi from the mud, it cools blood and clears heat. Bitterness dries dampness, and astringency consolidates, hence it primarily treats the absorption of dampness. (Comment by Zhong Chun) Mixed with mint leaves and fine tea powder, made into honey pills, sucked slowly after meals (3-5 pills), can resolve phlegm. For gingival ulcers and oral thrush, mix Hai Er Cha and Borax (Peng Sha) in equal parts and apply. For chancres and genital sores, mix one qian of Hai Er Cha, one fen of Pearl (Zhen Zhu), and half a fen of Borneol (Pian Nao), grind into powder, and apply. For various swellings and toxic sores, mix Hai Er Cha and Cicada Slough (Chan Tui) in equal parts, grind into fine powder, and apply externally mixed with bile from a male pig; effective. For prolapsed rectum due to Qi-heat, mix two fen of Hai Er Cha, five fen of male gallbladder bile (Xiong Dan), and one fen of Borneol, grind into powder, and apply to the anus mixed with human milk; the heat flows downward and the anus retracts. Also treats hemorrhoids.
