[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.
