混堂水：即今人浴池烧水供人沐浴的水，因人数众多，污垢积聚所致。人的气息熏蒸浸泡，体质虚弱的人接触后会感到昏晕，这种症状称为“晕堂”。这是因为人体之气与污水相互渗透交融的缘故。
此水可治疗疥癣、通利淋证及浊尿。
用于蛇鳞缠身之症。刘羽仪的验证方：饮用洗浴后的汤水，即可解毒。
用于痘疮。杭州士元的方法：痘疮发出八九日后出现黑陷，用混堂水煎煮药物，痘疮可立即起发。
《太元玉格新书》中记载了制作鸡神水的方法，《眼科要览》选录了其方剂。制作方法：选取一个大萝卜，开一个大孔，必须在靠近茎部的一端开口，不要伤及其根部，这样才能保持其活性。孔内放入一枚鸡蛋，然后将萝卜重新种在土地上，等待其发芽长叶成熟后，取出鸡蛋内的液体滴入眼中，视力可恢复如儿童般明亮。
具有明目、去除眼翳的功效。
泰西（西方）所制的日精油，《本草补》记载：其药材原料大多非中国本土所有，旅行者跋涉九万里将其带入中国，绝非寻常浅显之效，不可轻视它啊。用于治疗一切刀枪、木石撞击以及马踢、犬咬等外伤，能止痛并促进伤口愈合，有极大的奇效。用法：先观察伤口大小如何，如果伤口长宽且皮肤绽开，先用酒清洗擦拭干净，随即用线缝合，大约一寸三分的长度缝一针，缝合时不可太密。伤口较小者，无需缝合。缝合后，再次用酒清洗擦拭干净，将洁净瓷器中的油加热，取男人穿过的旧棉布，根据经线和纬线的长短，以伤口大小为度，逐缕蘸取热油，贴满疮口。再用男人穿过的旧布包裹，忌讳使用女人穿过的布料，等到三四天后解开，涂抹少许润油，像之前一样包扎牢固，数日即可痊愈。如果伤口日久血液干枯，稍微抓破或用刀刮开，使血水流通以通达药气，然后像之前一样包扎牢固。但血液过多会导致药物流失，所以无血不行，多血也不行。受伤处忌讳水和唾液，最应防范，如果伤口已经化脓或骨折，此油无益，不必使用。如果是心腹、耳、鼻、手足及各处骨节疼痛，确实属于风寒引起，而非燥热所致，则此油可以治疗。询问疼痛的具体部位，用油揉擦直至极热，然后用男人穿过的旧布包裹。用药期间，必须坐在密闭的房间内，切勿见风，并忌食寒冷等食物。（出自《本草补》）
Huntang Shui (Bathwater): Refers to the water heated in modern bathhouses for bathing. It becomes turbid and accumulates filth due to the large number of people. The vaporization of human qi and moisture can cause those with deficient constitutions to feel dizzy upon contact; this condition is termed "Yun Tang" (Dizziness in the Bath). This occurs because human qi permeates and blends with the water.
It treats scabies and tinea, and promotes urination in cases of stranguria and turbid urine.
For snake-scale entanglement on the body. Verified prescription by Liu Yuyi: Drinking the bathwater can detoxify the body.
For smallpox. Prescription from Hang Shi Yuan: If smallpox lesions turn black and sink after eight or nine days of eruption, decocting medicine with huntang shui can cause them to rise immediately.
The *Taiyuan Yuge Xinshu* records a method for preparing Jishen Shui (Chicken Spirit Water), which was selected in the *Yanke Yaolan* (Essentials of Ophthalmology). Preparation method: Select one large radish, cut a large hole near the stem end without damaging the root, so that it remains alive. Place one egg inside the hole, replant the radish in the ground, and wait until it sprouts leaves and matures. Extract the liquid from within the egg and apply it to the eyes; vision will become clear as that of a child.
It brightens the eyes and removes ocular opacities.
Rizhi Jing You (Sun Essence Oil) manufactured in the West. The *Bencao Bu* states: Its medicinal ingredients are mostly not native to China. Travelers have brought them across ninety thousand li to the Central Plains; they certainly possess effects far beyond ordinary remedies, and should not be underestimated. It treats all injuries caused by knives, spears, wood, stone, horse kicks, and dog bites, providing pain relief and promoting wound closure, with remarkable efficacy. Usage: First assess the size of the wound. If the wound is long and wide with split skin, first wash and wipe clean with alcohol, then suture with thread. Approximately one stitch per inch and three fen; sutures should not be too tight. For smaller wounds, suturing is unnecessary. After suturing, wash and wipe clean again with alcohol. Heat oil in a clean porcelain vessel. Take old cotton cloth worn by men, considering the warp and weft lengths, and use the wound size as the measure. Dip each strand/thread into the hot oil and apply it to cover the entire wound surface. Then wrap with old cloth worn by men; avoid using cloth worn by women. After three or four days, untie the dressing, apply a little moisturizing oil, and re-wrap securely as before. Healing occurs within a few days. If the wound has been present for a long time and blood is dry, slightly scratch or scrape it with a knife to allow blood and fluid to flow, thereby facilitating the penetration of medicinal qi, then re-wrap securely as before. However, excessive bleeding causes the medicine to run off, so neither lack of blood nor excessive blood is suitable. The injured area must be kept away from water and saliva, which should be strictly avoided. If the wound is already suppurating or involves bone fracture, this oil is of no benefit and should not be used. For pain in the heart, abdomen, ears, nose, hands, feet, and various joints, if it is indeed caused by wind-cold rather than dryness-heat, this oil can treat it. Identify the specific location of the pain, rub and massage with oil until extremely hot, then wrap with old cloth worn by men. During treatment, one must sit in a sealed room, avoid exposure to wind, and refrain from consuming cold foods and substances. (From *Bencao Bu*)
