（《拾遗》）
【主治】妇人难产，热酒服一钱（藏器）。
（《拾遗》）
【集解】藏器曰∶生南海畔，状如黄土，灰可浣衣。琉璃、玛瑙、玉石，以此灰埋之，
即烂如泥，至易雕刻。
【主治】白癜风、 疡风，重淋取汁，和醋敷之。以布揩破乃敷之，为疮勿怪（藏器）。
（《别录》下品）
【释名】灶心土。
弘景曰∶此灶中对釜月下黄土也。以灶有神，故号为伏龙肝，并以迂隐其名尔。今人又
用广州盐城屑，以疗漏血瘀血，亦是近月之土，盖得火烧之义也。
曰∶凡使，勿误用灶下土。其伏龙肝，是十年以来，灶额内火气积久自结，如赤色石
，中黄，其形貌八棱，取得研细，以水飞过用。
时珍曰∶按《广济历》作灶忌日云∶伏龙在不可移作。则伏龙者，乃灶神也。《后汉书
》言∶阴子方腊日晨炊而灶神见形。注云∶宜市买猪肝泥灶，令妇孝。则伏龙肝之名义，又
取此也。临安陈舆言∶砌灶时，纳猪肝一具于土，俟其日久，与土为一，乃用之，始与名符。
盖本于此。
《独孤滔丹书》言∶伏龙肝取经十年灶下，掘深一尺，有色如紫瓷者是真，可缩贺，伏
丹砂。盖亦不知猪肝之义，而用灶下土以为之也。
【气味】辛，微温，无毒。权曰∶咸。大明曰∶热，微毒。

治心痛狂癫，风邪蛊毒，妊娠护胎，小儿脐疮重舌，风噤反胃，中恶猝魇，诸疮（时珍）。

(From *Bencao Shiyi* [Supplement to Materia Medica])
[Indications] Dystocia in women; take one qian with hot wine. (Sun Zangqi)
(From *Bencao Shiyi* [Supplement to Materia Medica])
[Collection and Explanation] Sun Zangqi stated: It grows by the South Sea, resembling yellow earth; its ash can be used for washing clothes. Glaze, agate, jade, and stone buried in this ash will rot like mud, making them very easy to carve.
[Indications] Vitiligo (Bai Dian Feng), Yang Feng (a stubborn skin disease); take concentrated juice, mix with vinegar, and apply to the affected area. Wipe the broken skin with cloth before application; do not be surprised if sores appear. (Sun Zangqi)
(From *Mingyi Bielu* [Record of Famous Physicians], Lower Grade)
[Names] Zao Xin Tu (Furnace Heart Earth).
Tao Hongjing said: This is the yellow earth beneath the pot in the center of the stove. Because there is a spirit in the stove, it is called "Fu Long Gan" (Hidden Dragon's Liver), which is also a euphemistic name. Nowadays, people also use Guangzhou salt field earth powder to treat bleeding and blood stasis; this is also earth near the moon, presumably deriving meaning from fire burning.
Li said: When using it, do not mistake it for ordinary earth under the stove. Fu Long Gan is formed over ten years by the accumulation of fire energy inside the stove's forehead, resembling red stone, yellow in the middle, with an eight-prismatic shape. After obtaining it, grind it into fine powder and use it after water-floating purification.
Li Shizhen said: According to *Guangji Li* regarding taboo days for building stoves: "Where Fu Long resides, construction should not be moved." Thus, "Fu Long" refers to the Stove God. *Book of Later Han* states: Yin Zifang saw the Stove God manifest form while cooking breakfast on La Day. The annotation says: "One should buy pig liver mud to smear the stove, ensuring the wife's filial piety." Thus, the meaning of the name "Fu Long Gan" is derived from this. Chen Yu of Lin'an said: When building a stove, bury a whole pig liver in the earth; wait until it merges with the earth over time, then use it, which truly matches the name. This likely originates from here.
*Du Gu Tao Dan Shu* states: For Fu Long Gan, dig one chi deep under a ten-year-old stove; those colored like purple porcelain are genuine, capable of contracting He (possibly a typo or specific alchemical term) and subduing Cinnabar. This is likely due to ignorance of the pig liver meaning, using stove earth instead.
[Flavor and Properties] Pungent, slightly warm, non-toxic. Lei Xiao said: Salty. Ma Zhi said: Hot, slightly toxic.
[Indications] Metrorrhagia and hematemesis in women; stops coughing up blood against the reverse flow. Mix with vinegar and apply to carbuncles and swelling toxins (*Mingyi Bielu*). Stops epistaxis, intestinal wind leukorrhea, hematuria, seminal emission, promotes labor and delivery of the placenta, and treats infantile night crying (Ma Zhi).
