小儿初生饮半盏能解胎毒及出痘疹稀少是其功也(菽园杂记)
《春秋左传》中说：“土壤深厚，地下水深，居住在那里不会生病。”这是说地势高燥的缘故。我往年担任江表地区的郡守，那里地气卑湿，得了痔漏下血的病，将近二十年没有痊愈。不曾有一天不发作。景德年间，跟随皇帝巡幸洛阳；前年陪同祭祀汾阴，往返途中都安然无恙。今年退隐居住在嵩山脚下，井水很深几丈却极其甘美，这个病于是就好了。（出自杨亿《杨文公谈苑》）
黄庭坚在给曹使君的信中说：“您的公子患痈肿，也是因为天气亢旱，所以有热邪的人先受其害。如果脏腑秘滞不通，可以用犀角丸服用，使得大便流利顺畅，那么痈肿自然就会消退。如果有头痛发热，适宜用消风散。大概是因为脓液凝结不能溃破。像这样治疗，没有不好的。犀角丸的方子：甘草（炙）一两，生大黄一两，朴硝一两。先将甘草、大黄制成细末，研磨朴硝与之混合，用炼蜜制成梧桐子大小的药丸。初次服用二十丸，逐渐增加到三十丸，空腹时用温热水送服。（出自曾慥《道山清话》/注：原文标注为刀笔，实指曾慥或相关笔记，此处依原文标注）”
有一人患发背疽，肠胃外露，各种药物都不见效。一位医生教他用楸叶膏敷在外部，又用云母膏做成小丸子服用，吃完四两后，没过几天，云母就从皮肤透出，与楸叶膏粘连在一起，看疮口随即平复，功效也很奇特。他的方子是：在立秋日太阳未升起之时，采集楸叶熬成膏，敷治一切疮疡恶疮肿毒，立即痊愈，称为楸叶膏。（出自葛立方《韵语阳秋》）
还元水的方法是：腊月里用空坛子，不拘大小，用细布封口，系上绳子，浸入大粪坑中。日子久了，粪水渗入坛内，取出后埋在土中二三年，化为清水，完全没有秽气。凡是痈疽毒疮初发时，取一碗饮用，毒性即刻消散。这个方法很好，俗名叫做金汁。小儿刚出生喝半盏，能解除胎毒，以及出痘疹稀少，就是它的功效。（出自陆次云《菽园杂记》）
树汗（汗斑）调轻粉，用生姜切片蘸药擦拭，汗斑自然消退。（出自戴冠《雇缨杂录》）
从前有人肩部和髀部受伤，血流如涌出。医生用原蚕蛾炒成细末敷在上面，血立刻停止。另一说法是用真降香保留药性研成末贴敷，尤其奇妙。（出自俞文豹《吹剑续录》）
The *Zuo Zhuan* (Commentary of Zuo) states: "When the soil is deep and the groundwater is high, residing there prevents illness." This refers to the advantage of high and dry terrain. In my previous years, while serving as the prefect in the Jiangbiao region, where the local qi was low and damp, I suffered from hemorrhoids with bleeding for nearly twenty years without cure, never having a day without symptoms. During the Jingde era, accompanying the Emperor on his tour to Luoyang; and two years prior, accompanying sacrifices at Fenyin, I remained unharmed during both journeys. This year, upon retiring to reside at the foot of Mount Song, where the well water was deep (several zhang) yet extremely sweet and pure, this ailment finally ceased. (From Yang Yi's *Yang Wengong Tan Yuan*)
Huang Tingjian wrote in a letter to Envoy Cao: "Your honorable son suffers from carbuncles and swelling due to excessive heavenly heat; thus, those with internal heat are affected first. If the viscera are constipated and stagnant, one may take Xijiao Wan (Rhinoceros Horn Pill). Once bowel movements become smooth, the carbuncle will naturally subside. If accompanied by headache and fever, Xiaofeng San (Wind-Dispersing Powder) is appropriate. This is likely because pus has condensed but not ulcerated. Such treatment yields no failures. The prescription for Xijiao Wan (Rhinoceros Horn Pill): Licorice Root (roasted) 1 liang, Raw Rhubarb 1 liang, Mirabilite 1 liang. First, process Licorice and Rhubarb into fine powder, grind Mirabilite, mix them together, and refine honey to form pills the size of paulownia seeds. Initially take 20 pills, gradually increasing to 30 pills, taken on an empty stomach with warm water. (From *Dao Shan Qing Hua*, cited here as *Dao Bi*)"
A person suffered from a back carbuncle (Fa Bei), with intestines exposed, and various medicines failed to heal him. A physician instructed him to apply Qiuye Gao (Mulberry Leaf Ointment) externally, and also swallow Yunmu Gao (Mica Ointment) formed into small pills. After consuming four liang, within a few days, mica emerged through the skin, adhering to the Mulberry Leaf Ointment, and the wound surface flattened. The efficacy was remarkable. The method is: On the day of Start of Autumn, before sunrise, collect mulberry leaves and boil them into an ointment. Applied to all sores, malignant ulcers, swellings, and toxins, it heals immediately, hence called Qiuye Gao. (From Ge Fangli's *Yunyu Yangqiu*)
The method for making Huanyuan Shui (Return-to-Origin Water): In the twelfth lunar month, use an empty jar of any size, seal the mouth with fine cloth, tie it with a rope, and immerse it in a human feces pit. After many days, fecal liquid seeps into the jar. Remove it and bury it in the earth for two to three years until it transforms into clear water with absolutely no foul odor. When a carbuncle or toxic sore first appears, drink one bowl; the toxicity dissipates immediately. This method is excellent, commonly known as Jinzhi (Golden Juice). Infants drinking half a cup at birth can resolve fetal toxins and result in fewer chickenpox/smallpox lesions, which is its merit. (From Lu Ci Yun's *Shuyuan Zaji*)
For tree sweat (tinea versicolor), mix Qinfen (Calamine) with fresh ginger slices dipped in the medicine to wipe the area; the spots will naturally recede. (From Dai Guan's *Gu Ying Zalu*)
In the past, someone had a wound in the shoulder and thigh area with blood gushing out. A doctor used roasted silkworm pupae ground into fine powder applied to the wound, stopping the bleeding immediately. Another account suggests using genuine Agarwood (Xiang) preserved with its original properties, ground into powder and applied, which is even more miraculous. (From Yu Wenbao's *Chui Jian Xulu*)
