（《拾遗》）
【释名】时珍曰∶此山岩土石间所出泉，流为溪涧者也。《尔雅》云∶水正出，曰滥泉
；悬出，曰沃泉；仄出曰 泉。其泉源远清冷，或山有玉石美草木者为良；其山有黑土毒
石恶草者不可用。陆羽云∶凡瀑涌漱湍之水，饮之令人有颈疾。
颖曰∶昔在浔阳，忽一日城中马死数百。询之，云∶数日前雨，洗出山谷中蛇虫之毒，
马饮其水然也。
【气味】甘，平，无毒。
【主治】霍乱烦闷，呕吐腹空，转筋恐入腹，宜多服之，名曰洗肠，勿令腹空，空则更
服。人皆惧此，然尝试有效。但身冷力弱者，防致脏寒，当以意消息之（藏器）。
（《拾遗》）
【主治】有毒，杀人。洗诸疮皆瘥（藏器）。
（《拾遗》）
【集解】藏器曰∶乃古冢中食罂中水也，取清澄久远者佳。古文曰∶蔗留余节，瓜表遗
犀。言二物不烂，余皆成水也。
【气味】辛，平，有小毒。
【主治】鬼气中恶疰忤，心腹痛，恶梦鬼神，杀蛔虫。进一合，不可多饮，令人心闷。
又云，洗眼见鬼，未试（藏器）。
【附方】新一。噎疾∶古冢内罐罂中水，但得饮之即愈，极有神效。（《寿域方》）
（《拾遗》）
【集解】藏器曰∶此泽间小泉有赤蛇在中者，人或遇之，经雨取水服。
【气味】有小毒。
【主治】瘕结气，诸瘕，恶虫入腹，及咬人生疮者（藏器）。
(From *Bencao Shiyi* [Supplement to Materia Medica])
[Names] Li Shizhen states: This spring water emerges from the crevices of rocks and soil in mountain cliffs, flowing to form streams. The *Erya* states: A spring that flows vertically upward is called "Lanquan" (Overflowing Spring); a spring that hangs and flows down is called "Woquan" (Pouring Spring); a spring that flows obliquely is called "Quan" (Oblique Spring). Such springs have distant sources and cold, clear water quality; if the mountains contain jade or fine vegetation, the water is considered good; however, if the mountains contain black soil, toxic stones, or noxious plants, it should not be used. Lu Yu stated: Water from cascades and turbulent rapids, if consumed, causes neck diseases.
Ying stated: In Xunyang, hundreds of horses suddenly died in the city one day. Upon inquiry, it was said that rain a few days prior washed toxins from snakes and insects out of the valleys, and the horses drank this contaminated water.
[Flavor and Nature] Sweet, neutral, non-toxic.
[Indications] For cholera with restlessness, vomiting, abdominal emptiness, and muscle spasms (tetany) fearing ascent into the abdomen, drink abundantly. This is termed "washing the intestines." Do not let the abdomen feel empty; if it does, take more. People are often afraid of this, but trials show it is effective. However, for those with cold bodies and weak strength, care must be taken to prevent internal coldness; use discretion based on individual condition. (Cited from Zang Qi)
(From *Bencao Shiyi*)
[Indications] Toxic, can cause death. Used to wash various sores and ulcers, leading to healing. (Cited from Zang Qi)
(From *Bencao Shiyi*)
[Collection and Explanation] Zang Qi states: This is stagnant water found in earthenware jars within ancient tombs. Clear,澄 (clear), and long-stored water is preferred. Ancient texts say: "Sugarcane retains its nodes, melon rinds resemble rhino horn," meaning these items do not rot, while others decompose into water.
[Flavor and Nature] Pungent, neutral, slightly toxic.
[Indications] For "ghost qi," sudden evil invasion, chronic infectious diseases (zhu wu), heart and abdominal pain, nightmares, and spiritual disturbances; kills roundworms. Take one he (a unit of volume); do not drink excessively as it may cause chest stuffiness. It is also said that washing eyes with this water allows one to see ghosts, though this has not been tested. (Cited from Zang Qi)
[Attached Prescriptions] New Prescription 1. Dysphagia (Yie Ji): Drink water from jars in ancient tombs; recovery is immediate and highly effective. (From *Shouyu Fang*)
(From *Bencao Shiyi*)
[Collection and Explanation] Zang Qi states: This refers to small springs in marshes containing red snakes. If encountered by humans, the water is collected after rain for consumption.
[Flavor and Nature] Slightly toxic.
[Indications] For jia syndrome (abdominal masses due to qi stagnation), various jia conditions, poisonous insects entering the abdomen, and sores caused by snake bites. (Cited from Zang Qi)
