味咸，性热，有毒。（《寓意草》中提到，服用红铅会损伤脑部，其热性和毒性由此可见。张士材说：服用红铅后出现热症，饮用童便或人乳即可解毒。）用于解箭毒。以及治疗女劳复（因房事过早导致的热病复发）。月经带，用于治疗金创（金属利器造成的创伤）出血不止。（将其炙烤热后熨烫伤口。）又用于治疗虎、野狼咬伤。以及箭头嵌入腹部。（均烧成灰，用酒送服一方寸匕的量，每日三次。）《素问》称之为月经。又称之为天癸。邪术家称之为红铅。（李时珍说：女子属于阴类，以血为主，其血上应太阴，下应海潮，月亮有盈亏，潮汐有早晚，月经每月来潮一次，与之相符，所以称为月水、月信、月经。“经”是常的意思，有固定的规律。“天癸”，是天一生水的道理。邪术家称之为红铅，这是错误的名称。女子的月经，有的提前，有的推后，有的通畅，有的闭塞，这些属于病态。还有违背常规的情况，古人并未提及，不可不知道。有的在行经期只吐血、鼻出血，或者眼耳出血的，这叫做逆行；有的三个月来潮一次的，这叫做居经，俗名按季；有一年来潮一次的，这叫做避年；有一生都不来潮却能受孕的，这叫做暗经；有受孕之后，每月仍来月经并生产孩子的，这叫做盛胎，俗名垢胎；有受孕数月，突然大量出血而胎儿不堕落的，这叫做漏胎。这些虽然可以用气血有余或不足来解释，但也异于常态。女子十四岁天癸至，四十九岁天癸绝，这是常态。有女子十三四岁就生育孩子的，如褚记室所载，平江苏达卿的女儿十二岁受孕；有妇女五十六十岁还生育孩子的，如《辽史》所载，亟普的妻子六十多岁生了两个男孩一个女孩。这又是异常中的极端情况。学医的人对于这类情况，恐怕也应该留心。女子来月经时，体液污秽腥臭，所以君子远离它，认为它不洁净，会损耗阳气并导致疾病。煎膏制药、出痘疮、持戒修炼性命的人，都对此避忌，就是因为这个原因。现在有些方士邪术，鼓弄愚人，用方法获取童女初次来的经血服用，称之为先天红铅，巧立名目，多方配合，声称是《参同契》中的金华、《悟真篇》中的首经，都是指这种东西。愚人相信它，吞服作为秘方，往往引发丹疹，实在令人叹息厌恶。据萧丫真《金丹诗》云：“一等旁门性好淫，强阳复去采他阴，口含天癸称灵药，似恁洳沮枉用心。”唉，愚人看了这首诗，可以自我醒悟了。张士材过分夸大红铅能治病延年，这是不经之谈。男子患阴疮，因为不忌讳月经，导致阴部溃烂，用处女的血衲（沾染经血的布），在瓦上烧至存性，研成粉末，用麻油调和敷用。）
Salty in flavor, hot in nature, and toxic. (In *Yuyi Cao*, it is mentioned that taking Hongqian damages the brain, indicating its heat and toxicity. Zhang Shicai stated: If heat symptoms occur after taking Hongqian, drinking child's urine or human milk can detoxify it.) Used to antidote arrow poison. Also treats female labor relapse (recurrence of fever due to premature sexual intercourse). Menstrual cloths are used to treat bleeding from metal wounds (apply by heating them after roasting). It also treats bites from tigers, wild wolves, and arrows embedded in the abdomen (all burned to ash, taken with wine, one cun qi per dose, three times a day). The *Suwen* calls it menstruation. It is also called Tian Gui (Heavenly Water / Pubertal Essence). Cult practitioners call it Hongqian (Red Lead). (Li Shizhen said: Women belong to Yin and are primarily governed by blood. Their blood corresponds to the Moon above and the sea tides below. Just as the moon waxes and wanes, and tides rise and fall daily, menstruation occurs once a month, aligning with this pattern; hence it is called Yue Shui (Moon Water), Yue Xin (Monthly Trust), or Jing Jing (Menstruation). "Jing" implies constancy and regular rhythm. "Tian Gui" refers to the principle of Heaven generating Water. Calling it Hongqian is an erroneous name. Regarding menstrual disorders, some may come early or late, flow freely or be obstructed; these are pathological. There are also variations from the norm not previously discussed by ancients, which must be known. Some experience epistaxis, hematemesis, or bleeding from eyes/ears during their period; this is called Ni Xing (Retrograde Flow). Some menstruate only once every three months; this is called Ju Jing (Resident Period), colloquially known as seasonal. Some menstruate only once a year; this is called Bi Nian (Avoiding Year). Some never menstruate but can conceive; this is called An Jing (Hidden Period). Some continue to menstruate monthly even after conception and give birth; this is called Sheng Tai (Abundant Fetus), colloquially Gou Tai (Dust Fetus). Some experience heavy bleeding several months into pregnancy without miscarriage; this is called Lou Tai (Leaking Fetus). Although these can be explained by excess or deficiency of Qi and Blood, they deviate from the norm. For women, Tian Gui arrives at age fourteen (2x7) and ceases at age forty-nine (7x7); this is normal. However, there are exceptions: girls giving birth at thirteen or fourteen, as recorded by Chu Jishi (e.g., Su Daqing’s daughter conceiving at twelve); or women giving birth at fifty or sixty, as recorded in the *History of Liao* (e.g., Ji Pu’s wife bearing children in her sixties). These are extreme abnormalities. Medical students should pay attention to such cases. When women menstruate, the fluids are foul and impure; thus, gentlemen avoid them, considering them unclean and capable of damaging Yang Qi and causing disease. Preparations involving decoctions, treating smallpox, and those practicing ascetic cultivation all avoid menstruation for this reason. Currently, some charlatans deceive fools by collecting the first menses of virgin girls for consumption, calling it Xiantian Hongqian (Prenatal Red Lead). They invent names and complex formulations, claiming it is the "Jinhua" (Golden Flower) from *Can Tong Qi* or the "Shou Jing" (First Menses) from *Wu Zhen Pian*. Fools believe this and take it as a secret recipe, often developing drug eruptions (Dan Zhen), which is truly lamentable and disgusting. As Xiao Yazhen wrote in his *Jin Dan Shi*: "Those on heterodox paths love lust, forcing Yang to harvest Yin; holding Tian Gui in the mouth, they call it spiritual medicine; such muddy efforts are in vain." Alas, fools reading this poem can awaken themselves. Zhang Shicai’s exaggerated claims that Hongqian cures diseases and prolongs life are baseless. For men suffering from yin sores due to ignoring menstrual taboos, resulting in ulceration of the genitalia, use blood-stained cloth from a virgin girl, burned on tiles until the essence remains, ground into powder, and applied with sesame oil.)
