（宋嘉 ）
【气味】咸平，无毒。
【主治】主解毒箭，并女劳复。
【核】曰∶月水，《素问》谓之月经，又谓之天癸。丹家谓之月信，又谓之红铅。采取
合法，成服食上丹，否则非徒无益，而又害之矣。女子二七，月事始以时下而有子。经行三
日，时日不移者，为经，为尝；或先，或后，或通，或塞者，为病，为变。三月一行者，谓
之居经；一年一行者，谓之避年；一生不行而孕者，谓之暗经；受孕仍以时下者，谓之盛胎；
受孕数月，经忽大下者，谓之漏胎；每月数至，或至无休息，或大下崩决者，谓之病经；十
二而孕，六十尤乳者，谓之变生，皆非嘉品。采取上药，须择首经。一法，即收经水绵帛，
或纸，用童溺漂洗即落，乌梅煮汁点之，铅即澄淀于底，泌去黄水，淡灰 干，此属下乘。
一法，用黑铅作偃月，橐 ，经至系之，满则倾置盘内，以上乘秋石，少筛经水之上，即作
薄衣，浮结于上，轻轻取起，随筛随结，以尽为度，此属中乘。其最上乘者，俟女子二七，
天癸将至，眉心先有红气，光艳夺目，丹家所谓上应星，下应潮者是也。其法亦用偃月橐 ，
先以头生男乳，晒取成粉，轻抹橐 之内，次筛上乘秋石于乳粉之上，经至则系之，经下遂
结药于橐 之内矣。倾去黄水，随筛随系，以竟为度。首经者，中结枚子，或一或二或三；
次行者，仅有散砂，即无枚子。采得枚子，先炼五气上丹，制一金丸，径大九分，丸分两开
，中作子口；上下俱实五气上丹。子口处，须令均平，次以极圆青豆，置于金丸之中，上
下合成，则中有圆窍，即藏枚子于丹窍之内，以蜂蜡封固，子半之后，午半之前，护系童女
脐上；午半之后，子半之前，护系童男脐上。满四十九日，枚子遂长满其窍，用时如法服食。
不则仍如前法护系，此得之异授，不敢自私，用公海内。
先人云∶濒湖未见神奇，徒自妄诋，若得童女首经，内含至药。如不可得，即未经残破
女子者，亦堪服食。以天癸为生身之基，两精相搏，便生一人，亦奇异矣。一法用红铅三两，
先
色如桃花，仅得百厘，每用一厘，重绵裹护，子寅二时，纳左鼻孔，行数百息，即随息入脑
，尽此百厘，为返老还童，长生不死之至实也。欲识神异，以死人胫骨，镂一小孔，置数厘
于孔内，仍埋土中过宿，至明起视，枯骨如生；或置分许于磁盘内，覆磁杯于丹上，水和麦
面，封固其口四围，缓火炙之，麦面焦黑，俟冷开视，其丹尽渗杯内，击碎其砭，都成丹色
，仍以杯砭乳细，入釜温养，丹复提出，毫末不减，此亦异术也。
【 】曰∶服食家，择处子相好端洁，生辰在仲秋者，禀太阴金水之一气，作鼎甚良，
俟其蒸变已足，黄道已归，上应星，下应潮，天癸至，任脉通，太冲脉盛，月事以时下矣。
丹诀云∶三十时中两日半，二十八九君当算，落红满地是佳期，金水过时空涸乱，故必三缘
会合采取合宜，时中月望，乃结枚子如芥粒，不假人力为也，更炼龙虎两弦，退却阴符，进
添阳火，候七七光生，食之接延寿命。即女子未经破残，或生辰在四季余月者，如法采取，
亦可却病，岂小补云乎哉。近所尚者，先天一气已失，仅取糟粕剩余，不唯无补于形神，反
致燎炎其焦府，既失授受之源，亦且择非其鼎，宜乎见者闻者，弃之勿顾。
【宋嘉】
【气味】味咸，性平，无毒。
【主治】主治解毒箭（中毒箭），以及女劳复（因房事过早导致的疾病复发）。
【核】说：月经，《素问》中称为“月经”，又称为“天癸”（指促进生殖功能成熟的物质）。丹家（炼丹术士）称为“月信”，又称为“红铅”。采取方法合法，可炼成服食用的上丹；否则不仅无益，反而有害。女子十四岁（二七），月经开始按时来潮并能生育。经期持续三天，时间固定不变的，称为“经”，也称为“尝”；或提前、或推后、或通畅、或闭塞的，属于病态，属于变异。三个月来一次月经的，称为“居经”；一年来一次月经的，称为“避年”；一生不来月经却能怀孕的，称为“暗经”；怀孕后仍按时来月经的，称为“盛胎”；怀孕数月后突然大量出血的，称为“漏胎”；每月多次来月经，或者来时无休止，或者大量崩漏决堤般的，称为“病经”；十二岁就怀孕，六十岁还能哺乳的，称为“变生”，这些都不属于优良正常的品类。采取上等药材，必须选择处女初潮时的经血。一种方法，是收集经血时的丝绵或纸张，用童子的小便漂洗，经血渍即可脱落，再用乌梅煮出的汁液点染，铅质就会沉淀到底部，滤去黄色的水，用淡灰干燥，这属于下乘之法。另一种方法，用黑铅做成半月形容器，套在经血到来时系在身上，满了之后倾倒在盘内，将上乘的秋石（经过特殊处理的盐类矿物药）少量筛在经水上，就会形成薄衣状，浮结在上面，轻轻取起，随着筛选随着结集，以尽为止，这属于中乘之法。最上乘的方法，等待女子十四岁时，天癸将至，眉心先出现红色气色，光彩夺目，这是丹家所说的“上应星，下应潮”的现象。这种方法也用半月形容器，先用头生男婴的乳汁，晒干制成粉末，轻轻涂抹在容器内部，其次将上乘秋石筛在乳粉之上，经血到来时系在身上，经血下来后就在容器内结成药物了。倒去黄水，随着筛选随着系挂，以完成为度。初潮者，中间结成的颗粒像芥子，或一个、或两个、或三个；第二次来潮的，仅有散沙状的粉末，没有颗粒。采得颗粒后，先炼制五气上丹，制成一颗金丸，直径九分，丸子从中间剖开，中间做成子口；上下都填实五气上丹。子口处，必须令其平整，其次用极圆的青豆，放在金丸之中，上下合拢，则中间有圆孔，即将颗粒藏在丹药的孔穴之内，用蜂蜡封固，在子时过半之后、午时过半之前，护持系挂在童女的肚脐上；午时过半之后、子时过半之前，护持系挂在童男的肚脐上。满四十九天，颗粒就长满其孔穴，用时按法服用。如果不这样，仍像前法护持系挂，这是得到异人传授，不敢私藏，用来公开于天下。
前人曾说：李时珍（濒湖）未见神奇之处，只是胡乱诋毁，如果得到童女初潮经血，内含至药。如果得不到，即使是未经破身的残损女子，也值得服用。因为天癸是生成身体的基础，两精相搏，便生出一个人，也是奇异之事。一种方法用红铅三两，先处理到颜色如桃花，仅得百厘（重量单位），每次用一厘，用重绵包裹护持，在子时和寅时，纳入左鼻孔，呼吸数百次，气息随即进入脑部，用完这一百厘，就是返老还童、长生不死的极致实证。想要识别神异，可以用死人的胫骨，雕刻一个小孔，放置几厘丹药在孔内，仍然埋在土中过夜，到第二天早上起来看，枯骨如同活的一样；或者放置少许在磁盘内，用磁杯覆盖在丹药上，用水调和麦面，封固四周口沿，用慢火烘烤，麦面焦黑，等冷却打开看，丹药全部渗入杯内，击碎底下的砭石，都变成丹药颜色，仍以杯和砭石研磨细，放入釜中温养，丹药再次提出，毫发无损，这也是奇异之术。
【卢之颐】说：服食家，选择处女相貌端正洁净，生辰在仲秋的，禀受太阴金水的一气，作为鼎炉很好，等待其蒸变已足，黄道已归，上应星，下应潮，天癸至，任脉通，太冲脉盛，月经按时来潮了。丹诀说：“三十时中两日半，二十八九君当算，落红满地是佳期，金水过时空涸乱”，所以必须三缘会合采取适宜，时中月望，才结出颗粒如芥子大，不需要人力干预，再炼制龙虎两弦，退却阴符，进添阳火，等候七七光生，服用以延长寿命。即使是女子未经破身残损，或者生辰在四季余月的，按法采取，也可以祛病，岂止是小补呢。近来崇尚的，先天一气已经失去，仅取糟粕剩余，不仅对形体精神无补，反而导致燎炎其焦府（三焦腑），既然失去了授受的源头，也选择了非正确的鼎炉，难怪见者闻者，弃之不顾。
[Song Jia]
【Flavor and Nature】 Salty, neutral, non-toxic.
【Indications】 Mainly treats poison from venomous arrows (poisoned by venomous arrows) and female labor relapse (disease recurrence due to premature sexual activity).
【Analysis】 It is said: Menstrual blood (menstruation), referred to as "Jingyue" in the *Suwen* (*Basic Questions*), is also called "Tiangui" (substances promoting reproductive maturity). Alchemists call it "Yuexin" or "Hongqian" (Red Lead). If the collection method is lawful, it can be refined into superior elixirs for ingestion; otherwise, it brings no benefit but causes harm. At age fourteen (two sevens), a girl's menstruation begins to occur regularly, enabling her to bear children. If the menstrual period lasts three days with fixed timing, it is called "Jing" (regular menstruation) or "Chang" (trial); if it occurs early, late, freely, or obstructedly, it is pathological, representing variation. Menstruation occurring once every three months is called "Jujing" (residing menstruation); once a year is called "Binian" (avoiding the year); never menstruating yet conceiving is called "Anjing" (hidden menstruation); menstruating regularly during pregnancy is called "Shengtai" (abundant fetus); sudden heavy bleeding several months into pregnancy is called "Loutai" (leaking fetus); menstruating multiple times a month, without rest, or experiencing severe flooding and bursting is called "Bingjing" (pathological menstruation); conceiving at twelve and lactating at sixty is called "Baisheng" (transformed birth). These are not considered normal or excellent varieties. To collect superior medicinal material, one must select the first menstrual flow of a virgin. One method involves collecting silk or paper used during menstruation, rinsing it with urine from an uncircumcised boy until the blood stains fall off, then treating it with juice boiled from dark plums (*Wumei*). The lead will settle at the bottom. Filter out the yellow water and dry with light ash; this belongs to the inferior grade. Another method uses black lead shaped like a crescent moon, tied to the body when menstruation arrives. When full, pour it into a dish, sprinkle superior "Qiushi" (autumn stone, a processed mineral salt) lightly over the menstrual water. A thin film will form and float on top. Gently remove it, continuing to sift and collect until finished; this belongs to the intermediate grade. The highest grade waits until the girl is fourteen, when Tiangui is about to arrive. A red aura appears first at the glabella, dazzling in brightness. This is what alchemists call "responding to the stars above, responding to the tide below." This method also uses a crescent container. First, take milk from a first-born male infant, dry it into powder, and lightly smear it inside the container. Then sieve superior Qiushi onto the milk powder. When menstruation arrives, tie the container to the body. As menstrual blood flows, it forms medicine inside the container. Pour out the yellow water, sifting and tying continuously until complete. For the first menstruation, the formed particles resemble mustard seeds, either one, two, or three; for subsequent flows, only scattered sand-like powder remains, without particles. After obtaining the particles, refine them into "Wuqi Shangdan" (Five-Qi Superior Elixir), forming a golden pill with a diameter of nine fen. Split the pill in half, creating a socket in the middle. Fill both halves with Wuqi Shangdan. Ensure the socket surface is level. Place a perfectly round green bean inside the golden pill. Join the top and bottom halves, creating a central cavity. Hide the particle within the elixir's cavity, sealing it firmly with beeswax. Between the halfway point of Zi hour (11 PM-1 AM) and Wu hour (11 AM-1 PM), protectively tie it to the navel of a virgin girl. Between the halfway point of Wu hour and Zi hour, protectively tie it to the navel of a virgin boy. After forty-nine days, the particle fills the cavity. Use according to method for ingestion. If not done so, continue protective tying as before. This was received from an unusual transmission and is not kept private but made public for all.
My ancestor said: Li Shizhen (Binhu) did not see the miraculous effects and merely slandered it blindly. If one can obtain the first menstrual flow of a virgin, it contains supreme medicine. If unavailable, even that of a damaged virgin who has not been sexually active is suitable for ingestion. Since Tiangui is the foundation of bodily generation, the union of two essences creates a person, which is indeed wondrous. One method uses three taels of Hongqian, processed until the color resembles peach blossoms, yielding only one hundred li (weight unit). Use one li each time, wrap it securely in heavy silk, and insert it into the left nostril during Zi and Yin hours. Breathe hundreds of breaths, allowing the essence to enter the brain with the breath. Consuming this entire hundred li constitutes the ultimate reality of reversing aging and achieving immortality. To identify its spiritual properties, carve a small hole in a dead person's tibia bone, place a few li of the elixir inside, bury it in soil overnight. The next morning, upon inspection, the dry bone appears alive. Alternatively, place a small amount in a porcelain dish, cover the elixir with a porcelain cup, seal the edges with wheat flour paste mixed with water, and bake slowly over low heat. When the flour turns charred black, let it cool. Upon opening, the elixir has fully permeated the cup. Crush the underlying stone, which now resembles the elixir's color. Grind the cup and stone finely, warm-nourish in a pot, retrieve the elixir, which remains unchanged in weight. This is also a miraculous technique.
[Lu Zhiyi] says: Those practicing ingestion select virgins with dignified and clean appearances, born in mid-autumn, who inherit the qi of Taiyin Metal and Water. They serve as excellent cauldrons. Wait until their transformation is sufficient, the Yellow Path returns, they respond to stars and tides, Tiangui arrives, the Ren Mai (Conception Vessel) opens, the Chong Mai (Penetrating Vessel) becomes abundant, and menstruation occurs regularly. The alchemical verse states: "In thirty shichen, there are two and a half days; calculate twenty-eight or twenty-nine. When red falls covering the ground, it is the auspicious date; when Metal and Water pass, emptiness leads to chaos." Therefore, one must wait for the convergence of three affinities to collect appropriately. At the midpoint of the month, particles like mustard seeds form naturally, without human intervention. Further refine Longhu Liangxian (Dragon and Tiger Two Strings), retreat Yin Fu, advance Yang Fire. Wait for the light to generate after seven sevens, then ingest to extend life. Even if the girl has not been sexually active, or was born in other months of the four seasons, collecting according to method can also dispel disease, far exceeding minor benefits. What is currently popularized has lost the Primordial Qi, taking only dregs and residues. Not only does it fail to nourish form and spirit, but it also causes inflammation in the Jiaofu (Sanjiao/Fire Ministry). Having lost the source of transmission and chosen the wrong cauldron, it is no wonder that those who see and hear discard it without looking back.
