浴。浴讫当大虚惫。可随病与药及饮食补养。非有病患。不宜轻入。（汪颖曰∶庐山有温
泉、方士往往教患疥癣风癞杨梅疮者、饱食入池久浴、得汗出乃止、旬日自愈也、藏器曰
、下有硫黄、即令水热、犹有硫黄臭、硫黄主诸疮、故水亦宜、然当其热处、可 猪羊熟鸡

泉多作硫黄气、浴之则袭人肌肤、唯新安黄山是朱砂泉、春时水即
微红色、可煮茗、长安骊山是矾石泉、不甚作气也、朱砂泉虽红而不热、当是雄黄尔

甘咸平。下膈疏痰止吐。阿井在兖州阳谷县。即古东阿县也。（笔谈云∶古说济水伏流

青州范公泉、亦济水所注、其水用造白丸子、利膈化痰。）
甘平。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

、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。）此山岩土石间所出
泉。流为溪涧者也。（尔雅云∶水正出曰槛泉、悬出曰沃泉、反出曰泛泉、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、陆羽茶经曰∶凡瀑涌漱湍之水
、饮之令人有颈疾、汪颖曰∶昔在浔阳、忽一日、城中马死数百、询之云∶数日前雨、洗出
山谷蛇虫之毒、马饮其水然也。）
温泉，又名温汤。
其性味辛、热，带有微毒。主治各种风邪引起的筋骨挛缩，以及肌肤皮肤的麻木不仁（顽痹）、手足活动不利、不长眉毛头发、疥疮癣疾等病症，这些病位主要在皮肤和骨节之间。
用于洗浴。洗浴完毕后身体会感到极度虚弱疲惫，可以根据病情给予药物及饮食进行补养。如果没有病患，不宜轻易进入温泉浸泡。（汪颖说：庐山有温泉，方士常常教导患有疥疮、癣疾、风癞、杨梅疮的人，吃饱饭后进入池中长时间浸泡，直到出汗才停止，十天左右即可自愈。陈藏器说：泉下有硫黄，使水温升高，水中有硫黄的臭味。硫黄主治各种疮疡，所以泉水也适宜治疗，但在热气最盛的地方，可以煮猪、羊、熟鸡蛋。这里的泉水多带有硫黄气味，洗浴时热气袭人肌肤。只有新安的黄山是朱砂泉，春天时水呈微红色，可以用来煮茶。长安骊山是矾石泉，不怎么产生气味。朱砂泉虽然水红但不热，应当是雄黄。有砒石的地方也有温泉，洗浴会有毒性。）
阿井水，味甘、咸，性平。能下行至膈部，疏通痰浊，止住呕吐。阿井位于兖州阳谷县，就是古代的东阿县。（沈括《笔谈》说：古书记载济水在地下伏流，现在历下凡是挖掘地下都能发现流水，东阿也是济水流经的地方。济水性趋向下行，水质清澈且比重较大，用它可以搅动浊水使其变清，因此可以用青州范公泉的水来制作白丸子，以利于膈部、化痰。）
山岩泉水，味甘，性平。主治霍乱引起的烦闷、呕吐，腹部空虚导致的转筋（肌肉痉挛）。担心毒素进入腹中，宜多服用此水。（这种方法名叫“洗肠”，不要让腹部空着，如果空了就要再喝。人们都害怕这样做，但尝试过确实有效。只是对于身体寒冷、力气微弱的人，要防止导致内脏受寒，应当根据具体情况斟酌处理。）这种泉水是从山岩土石间流出的，汇聚成溪涧。（《尔雅》说：从正下方涌出的是槛泉，从高处悬挂流出的是沃泉，反向流出的是泛泉。这些泉水源头远，水质清冷。如果山上产玉石、长美好的草木，则泉水优良；如果山上有黑土、有毒石头和恶草，则不可使用。陆羽《茶经》说：凡是瀑布奔涌、急流冲刷的水，饮用会导致颈部疾病。汪颖说：过去在浔阳，忽然有一天，城里死了数百匹马，询问原因说是几天前下雨，冲出了山谷里蛇虫的毒素，马喝了这样的水所致。）
Hot Spring, also known as Warm Soup.
Its nature is acrid (Pungent), hot, with slight toxicity. It treats various wind-induced tendon and bone contractions, as well as skin and flesh numbness (stubborn bi-syndrome), inability to move hands and feet, absence of eyebrows and hair, scabies, tinea, and other diseases located in the skin and joints.
Used for bathing. After bathing, one may feel extremely weak and exhausted; medicinal herbs and dietary supplements should be administered according to the condition to nourish the body. If there is no illness, it is not advisable to enter lightly. (Wang Ying said: There are hot springs in Mount Lu. Alchemists often advise patients suffering from scabies, tinea, leprosy, or yaws to eat a full meal before entering the pool for a long soak, stopping only when sweat appears, which leads to self-healing within ten days. Chen Cangqi said: Sulfur is present beneath the spring, heating the water, which retains a sulfur odor. Sulfur treats various sores, hence the water is suitable. However, at the hottest spots, pigs, sheep, and boiled eggs can be cooked. The water here often has a sulfur smell; bathing exposes the skin to intense heat. Only the Zhu Sha Spring on Huangshan in Xin'an is a cinnabar spring; in spring, the water turns slightly red and can be used to brew tea. The Li Shan spring in Chang'an is an alum stone spring and produces little odor. Although the Zhu Sha spring water is red, it is not hot, likely containing realgar. Springs near arsenic stones are toxic for bathing.)
A Well Water, sweet and salty in taste, neutral in nature. It descends to the diaphragm, disperses phlegm, and stops vomiting. A Well is located in Yanggu County, Yanzhou Prefecture, which was ancient Dong'e County. (Shen Kuo's *Brush Talks* states: Ancient texts mention the Ji River flowing underground. Now, wherever digging reveals water, it is flowing water. Dong'e is on the course of the Ji River. Its nature tends downward; the water is clear and heavy. When used to stir turbid water, it clarifies it. Therefore, water from Fan Gong Spring in Qingzhou, also fed by the Ji River, is used to make White Pills to benefit the diaphragm and resolve phlegm.)
Mountain Rock Spring Water, sweet in taste, neutral in nature. It treats dysentery-like symptoms (Huo Luan) involving restlessness, vomiting, and abdominal emptiness leading to muscle spasms (tendon twitching). To prevent toxins from entering the abdomen, it is advisable to drink this water frequently. (This method is called "washing the intestines." Do not let the abdomen remain empty; if empty, drink more. People fear this, but attempts have proven effective. However, for those with cold bodies and weak strength, care must be taken to avoid causing cold damage to the viscera; judgment should be exercised based on individual conditions.) This type of spring emerges from between rocks and soil in mountains, flowing into streams and ravines. (*Erya* states: Water emerging straight up is called Kan Spring; water hanging down is called Wo Spring; water flowing backward is called Fan Spring. These springs have distant sources and cold, clear water. Springs on mountains with jade stones and fine vegetation are good; those with black soil, poisonous stones, and noxious grasses are unusable. Lu Yu's *Classic of Tea* states: Water from rushing waterfalls and turbulent currents causes neck diseases if drunk. Wang Ying said: Once in Xunyang, hundreds of horses died suddenly in the city. Inquiry revealed that recent rains had washed out snake and insect toxins from the valleys, and the horses drank this contaminated water.)
