黄石中间有淡白色的斑点。因此得名“花”。《图经本草》中称为花蕊石。（陈藏器注）
味酸、涩，气平。属于入厥阴经血分的药物。主治金疮出血，治疗妇人血晕及恶露不尽，以及一切失血和损伤。治疗内漏（体内慢性出血）和目翳（角膜云翳）。又能促使死胎排出，脱落胞衣，去除恶血。恶血消散后，胎与胞衣便无滞留之患。李东垣曾说：胞衣不下，用收敛性质的药物反而可以使其下行。所以赤石脂也能促进胞胎排出，与此药道理相同。（李时珍注）将花蕊石与硫黄一同研磨成末，外敷于金疮上，效果极佳。
有人突然被金属利器所伤，来不及进行其他治疗时，只需刮取药末敷在伤口上也有效。（苏颂注）花蕊石是阴性的石头，其功效专在于止血，能使血液化为水状，这是利用其酸性来收敛的缘故。（李时珍注）花乳石是酸、辛、温性的药物，功效专于止血，而其酸敛之气又能化瘀，所以敷治金疮时伤口能迅速愈合，且不会化脓。（陈实功注）
花蕊石散，治疗各种金属利器、箭簇造成的创伤，以及跌打损伤。被狗咬至假死状态的人，紧急将药粉掺入伤口，血液会化为黄水，再次掺药便能苏醒，且不再疼痛。如果是内部损伤，血液进入脏腑，煎煮童便（儿童尿液），加入少许酒，加热调服一钱，立即见效。牲畜角抵受伤，肠子脱出但未破损的，紧急将其纳入腹腔，用桑白皮线缝合伤口，掺入药粉，血止后立即存活。妇人产后败血未尽，出现血晕，恶血攻心，胎死腹中，或胎衣不下，只要心头尚温暖，紧急用童便调服一钱，排出如猪肝状的恶物，终身不再患血风、血气病。如果膈上有瘀血化为黄水，随即吐出，或随小便排出，也非常有效。配方：用硫黄四两，花蕊石一两，共同研为粗末，拌匀。装入瓦罐中，用胶泥密封加固，晒干后，放置在砖上。（砖上刻有八卦五行字样）。用炭一秤，紧密围绕瓦罐。从巳午时（上午9点至下午3点）开始从下方向上生火，直到炭烧尽，冷却后取出，研为细末，瓶装备用。对于多年的白内障（障翳），用花乳石水飞法处理后焙干，配防风、川芎、牛蒡子、甘菊花、白附子各一两，炙甘草半两，研为细末。每次服用半钱，用腊茶送服。
〔论述〕 花乳石产于西方土地，它在血证的治疗上似乎能通过化瘀来达到止血的目的，这或许符合“以母气召子”的道理呢？凡是人不属于阴虚而患有血逆证的，通常应有瘀血存在，使用花乳石以化瘀为止血，有奇效。如花蕊石散所治疗的产后瘀血危重证候，使得患者终身不再患血风、血气病。大概这种药物的化瘀作用，似乎有助于恢复血液的本元，既不属于强行止血，也不属于峻猛导泻以免加重虚损。临证时要审慎判断是否适用，难道不是借助它迅速奏效的优势吗？那些血逆证不属于阴虚的，多属于气虚不能引血归经，这本来另有补气药剂，且应禁用寒凉药物。然而又有偶尔感受寒凉导致血液凝涩而逆乱的，此时补气用药犹宜稍作等待，像这类药物应当是应对这种情况的良好药剂。
凡是虚劳导致的吐血，多是火炎迫血上行所致。除非膈上原有瘀血停聚凝结者，才可以暂时使用。但也必须配合多服童便。如果没有瘀血，则不宜内服。至于因火炎血溢导致的吐血，不属于内伤血凝、胸膈板痛的情况，忌用此药。（陈实功注）
〔炮制〕 凡是用于丸剂或散剂，需用罐子密封加固，经过顶火煅烧，以去除火毒，研细后用水飞法处理，晒干后使用。
Yellow stone with pale white spots in the middle. Hence the name "Flower". *Tu Jing Ben Cao* (Illustrated Classic of Materia Medica) refers to it as Huarui Shi (Flower Stamen Stone). (Chen Zangqi's annotation)
Taste: sour, astringent. Nature: neutral. It is a drug entering the Jueyin meridian blood level. It primarily treats bleeding from metal wounds, uterine syncope due to blood stasis and lochia retention in women, as well as all types of hemorrhage and trauma. It treats internal leakage (chronic internal bleeding) and corneal nebula (clouding of the cornea). It can also expel dead fetus and shed the placenta, removing bad blood. Once the bad blood dissipates, there will be no obstruction for the fetus and placenta. Li Dongyuan stated: for retained placenta, astringent agents can induce its expulsion. Therefore, Chishi Zhi (Red Halloysite) can also facilitate the expulsion of the placenta, sharing the same principle. (Li Shizhen's annotation) When mixed with Liu Huang (Sulfur) and ground into powder, applied externally to metal wounds, it is extremely effective.
For those suddenly injured by sharp metal instruments without time for other treatments, simply scraping the powder and applying it to the wound is also effective. (Su Song's annotation) Huarui Shi is a yin stone; its efficacy specializes in stopping bleeding, transforming blood into water-like fluid, utilizing its sour property to astringe. (Li Shizhen's annotation) Hua Ru Shi is a sour, acrid, and warm drug. Its efficacy specializes in stopping bleeding, while its sour and astringent qi can also resolve blood stasis. Thus, when applied to metal wounds, it promotes rapid healing without suppuration. (Chen Shigong's annotation)
Huarui Shi San (Flower Stamen Stone Powder) treats all injuries caused by metal blades, arrowheads, and blunt force trauma. For individuals bitten by dogs to the point of apparent death, urgently apply the powder to the wound; the blood transforms into yellow fluid. Applying again restores life, and pain ceases. In cases of internal injury where blood enters the zang-fu organs, decoct Tong Bian (Child's Urine), add a small amount of wine, heat, and administer one qian orally for immediate effect. For livestock injured by horn goring, if intestines are prolapsed but intact, urgently reduce them into the abdominal cavity, suture using mulberry root bark thread, apply the powder, stop bleeding, and restore life immediately. For postpartum women with incomplete expulsion of lochia, uterine syncope, malignant blood rushing to the heart, intrauterine fetal death, or retained placenta, provided the heart area remains warm, urgently administer one qian mixed with Tong Bian. This expels foul matter resembling pig liver, preventing future occurrences of Blood Wind and Blood Qi disorders. If blood above the diaphragm transforms into yellow fluid, it can be vomited out or excreted via urine, which is very effective. Formula: Use four liang of Liu Huang (Sulfur) and one liang of Hua Ru Shi, grind together into coarse powder, mix evenly. Place in a clay jar, seal tightly with gum mud, dry in the sun, and place on a brick inscribed with Bagua and Five Elements characters. Surround with one cheng of charcoal. Ignite fire from below starting at Si-Wu hours (9 AM - 3 PM), burn until charcoal is consumed, cool down, remove, grind into fine powder, and store in a bottle. For chronic cataracts (Zhang Yi), process Hua Ru Shi by water levigation and calcination, combine with Fang Feng (Saposhnikovia Root), Chuan Xiong (Ligusticum Rhizome), Niu Bang Zi (Arctium Fruit), Gan Ju Hua (Chrysanthemum Flower), Bai Fu Zi (Arisaema Rhizome) each one liang, and Zhi Gan Cao (Prepared Licorice Root) half a liang. Grind into powder. Take half a qian per dose, washed down with aged tea.
[Discussion] Hua Ru Shi originates from western regions. In treating blood disorders, it seems to achieve hemostasis through resolving stasis, possibly adhering to the principle of "calling the child with the mother's qi." For patients not suffering from yin deficiency but experiencing rebellious blood flow, stasis is likely present. Using Hua Ru Shi to resolve stasis and stop bleeding yields miraculous effects. As seen in the treatment of critical postpartum blood stasis syndromes by Huarui Shi San, patients remain free from Blood Wind and Blood Qi disorders for life. The stasis-resolving property of this herb seems to restore the original state of blood, neither forcibly stopping bleeding nor harshly purging to exacerbate deficiency. Clinicians must carefully assess indications. Does it not rely on its rapid efficacy? Rebellious blood flow not due to yin deficiency often stems from qi deficiency failing to guide blood back to the meridians. This typically requires qi-tonifying formulas and contraindicates cold-natured drugs. However, in cases of sudden cold invasion causing blood coagulation and rebellion, qi-tonifying measures may need delay; such herbs like this serve as appropriate remedies.
For hemoptysis due to consumptive fever, it is mostly caused by fire flaring up forcing blood upward. It can only be temporarily used if there is pre-existing stasis stagnation above the diaphragm. Even then, it must be taken with large amounts of Tong Bian (Child's Urine). If no stasis exists, internal use is inappropriate. For hemoptysis caused by fire flaring and blood overflow, not due to internal injury and blood coagulation accompanied by chest rigidity and pain, it is contraindicated. (Chen Shigong's annotation)
[Processing] For use in pills or powders, seal in a jar, roast over top-fire to eliminate fire toxicity, grind finely, process by water levigation, dry, and use.
