【释名】乌金（《纲目》）、陈玄（《纲目》）、玄香（《纲目》）、乌玉 。
时珍曰∶古者以黑土为墨，故字从黑土。许慎《说文》云∶墨，烟煤所成，土之类也，
故从黑土。刘熙《释名》云∶墨者，晦也。
【集解】宗 曰∶墨，松之烟也。世有以粟草灰伪为者，不可用；须松烟墨方可入药，
唯远烟细者为佳，粗者不可用。今高丽国所 墨于中国，不知何物合，不宜入药。 延有石
油，其烟甚浓，其煤可为墨，黑光如漆，不可入药。
时珍曰∶上墨，以松烟用 皮汁解胶和造，或加香药等物。今人多以窑突中墨烟，再三
以麻油入内，用火烧过造墨，谓之墨烟；墨光虽黑，而非松烟矣，用者详之。石墨见石炭下。

[Compendium of Materia Medica]
[Collected Explanations] Li Shizhen stated: This is the black soil collected from the walls of kilns used for smoking cowhide and from the flues of brick-and-tile kilns.
[Therapeutic Actions] For white alopecia capitis (tinea capitis), scabies, and tinea versicolor accompanied by itching, pain, and oozing fluid. Take the soot-gum (Yanjiao) from the cowhide kiln wall, grind it into powder, mix with sesame oil, and apply topically. Alternatively, mix with a small amount of calomel (Qingfen) (Li Shizhen).
[Supplementary Prescriptions] Three new prescriptions.
Cowhide blood tinea: Yanjiao 3 qian, Hanshuishi (Calcitum) 3 qian, Baifan (Alumen) 2 qian, Huajiao (Zanthoxyli Fructus) 1.5 qian. Grind into powder, mix with lard from the twelfth lunar month, and apply externally. (From *Jide Tang Fang*)
Xiaoke yin yin (Polydipsia due to Xiao Ke): Black coal from the flue of a tile kiln, dry and resembling iron slag, half jin. Grind into powder, add four liang of fresh ginger, pound together, place in a silk bag, soak in five sheng of water to extract juice, drink five he each time. (From *Shengji Lu*)
Retention of placenta: A pinch (three fingers' width) of black soil from behind the flue, taken with wine at the fifth watch (early morning). (Chen Zangqi)
[Song Dynasty *Kaibao Bencao*]
[Names] Wujin (Gold Black) (*Bencao Gangmu*), Chenxuan (Dark Mystery) (*Bencao Gangmu*), Xuanxiang (Dark Fragrance) (*Bencao Gangmu*), Wuyu (Black Jade).
Li Shizhen stated: In ancient times, black earth was used to make ink, hence the character 'Mo' consists of 'black' and 'earth'. Xu Shen in *Shuowen Jiezi* said: "Ink is formed from soot, belonging to the earth category," thus the character includes black and earth. Liu Xi in *Shiming* said: "Mo means darkness."
[Collected Explanations] Su Song stated: Ink is the smoke of pine trees. There are fakes made from grain straw ash in the world, which cannot be used; only pine-soot ink can be used for medicine, and the fine soot collected from a distance is best, while coarse soot is unusable. The ink currently imported from Goryeo into China is made of unknown substances and is not suitable for medicinal use. Yanzhou has petroleum; its smoke is very thick, and its coal can be made into ink, which is black and glossy like lacquer, but it cannot be used for medicine.
Li Shizhen stated: The aforementioned inks are made using pine soot mixed with hide glue dissolved in liquid, or with added aromatic herbs. Nowadays, people mostly use soot from kiln flues, repeatedly adding sesame oil and firing it to make ink, called "soot ink"; although this ink is black and shiny, it is no longer pine soot. Users should distinguish carefully. Graphite is described under the entry for Shi Tan (Coal). Ink from the squid (Wuzei Yu) and horse treasure ink (Ma Zhi Bao Mo) are described in their respective entries.
[Flavor and Toxicity] Acrid, warm, non-toxic.
[Therapeutic Actions] Stops bleeding, promotes tissue regeneration, heals metal wounds, treats postpartum syncope (blood晕), sudden heavy uterine bleeding (Beng Zhong); take vinegar-ground ink orally. Also stops bloody dysentery and pediatric Ke Wu (sudden fright/illness); grind, sieve, and take with warm water. Also treats foreign bodies/thorns entering the eye; apply/massage on the pupil (*Kaibao Bencao*). Promotes urination, regulates menstruation, treats carbuncles and swellings (Li Shizhen).
[Elucidation] Zhu Zhenheng stated: Ink belongs to Metal and contains Fire; it is very potent when used medicinally, and its nature can stop bleeding.
[Supplementary Prescriptions] Ten old prescriptions, six new prescriptions.
