妇人有一交合则流血不止，虽不至于血崩之甚，而终年累月不得愈，未免血气两伤，久则恐有血枯经闭之忧。
此等之病，成于经水正来之时交合，精冲血管也。夫精冲血管，不过一时之伤，精出宜愈，何以久而流红？不知血
管最娇嫩，断不可以精伤。凡妇人受孕，必于血管已净之时，方保无虞。倘经水正旺，彼欲涌出而精射之，则欲出
之血反退而缩入，既不能受精而成胎，势必至集精而化血。交感之际，淫气触动其旧日之精，则两相感召，旧精欲出，
而血亦随之而出。治法须通其胞胎之气，引旧日之集精外出，而益之以补气补精之药，则血管之伤，可以补完矣。
方用引精止血汤。
人参（五钱） 白术（一两，土炒） 茯苓（三钱，去皮） 熟地（一两，九蒸） 山萸肉（五钱，蒸） 黑姜（一
钱） 黄柏（五分） 芥穗（三钱） 车前子（三钱，酒炒）
水煎。连服四剂愈，十剂不再发。此方用参术以补气，用地萸以补精，精气既旺，则血管流通；加入茯苓、车前
以利水与窍，水利则血管亦利；又加黄柏为引，直入血管之中，而引夙精出于血管之外；芥穗引败血出于血管之内；
黑姜以止血管之口。一方之中，实有调停曲屈之妙，故能祛旧病而除陈 。然必须慎房帏三月，破者始不至重伤，
而补者始不至重损，否则不过取目前之效耳。其慎之哉！宜寡欲。
眉批∶欲种子者，必将落红后，即三十时辰，两日半也。经来之时，数足三十时辰，便可入房。一日男，二
日女，三日男，四日女，五日男，六日女，过七日即不能受孕矣。
歌括∶妇人交合宫血流，恐有血枯精闭忧。
治法须通胞胎气，补精益气病可瘳。
引精止血熟地黄，参术茯苓萸肉姜。
黄柏荆芥车前子，服药还须慎帏房。
A woman may experience continuous bleeding after every act of intercourse. Although it may not be as severe as metrorrhagia (profuse uterine bleeding), if it persists year after year without healing, it inevitably leads to a dual deficiency of Qi and Blood. Over time, there is a fear of developing blood exhaustion and amenorrhea (cessation of menstruation).
This condition arises from intercourse during the flow of menstrual blood, where semen impacts the blood vessels. While the impact of semen on the blood vessels causes only temporary injury, and should heal once the semen is expelled, why does the red bleeding persist? The truth is that the blood vessels are extremely delicate and cannot withstand injury from semen. For conception to occur, it must happen when the blood vessels (uterine lining) have been completely cleared of menstrual blood to ensure safety. If intercourse occurs while menstrual blood is abundant and surging, the incoming semen causes the outgoing blood to retreat and retract. Consequently, fertilization cannot take place, and the accumulated semen transforms into blood. During intercourse, sexual energy stirs up the old accumulated semen, leading to mutual resonance; the old semen desires to exit, and the blood follows it out. The treatment method requires unblocking the Qi of the uterus and womb, guiding the old accumulated semen out, and supplementing with herbs that tonify Qi and essence. In this way, the injury to the blood vessels can be healed. The formula used is Jingjing Zhixue Tang (Semen-Guiding Hemostatic Decoction).
Ren Shen (Ginseng Radix et Rhizoma, 5 qian), Bai Zhu (Atractylodis Macrocephalae Rhizoma, 1 liang, stir-fried with soil), Fu Ling (Poria, 3 qian, peeled), Shu Di Huang (Prepared Rehmanniae Radix, 1 liang, steamed nine times), Shan Yu Rou (Corni Fructus, 5 qian, steamed), Hei Jiang (Blackened Ginger Rhizome, 1 qian), Huang Bo (Phellodendri Cortex, 0.5 fen), Jie Sui (Schizonepetae Spica, 3 qian), Che Qian Zi (Plantaginis Semen, 3 qian, stir-fried with wine).
Decoct in water. Take continuously for four doses to achieve cure; ten doses will prevent recurrence. This formula uses Ren Shen and Bai Zhu to tonify Qi, and Di Huang and Shan Yu Rou to tonify Essence. Once Qi and Essence are robust, the blood vessels become patent. Fu Ling and Che Qian Zi are added to promote diuresis and open orifices; when water pathways are clear, blood vessels also become clear. Huang Bo is added as a guide herb to enter directly into the blood vessels and draw out retained semen from within them. Jie Sui guides stagnant blood out from inside the blood vessels. Hei Jiang seals the openings of the blood vessels. Within this single formula lies the subtle art of harmonious regulation, thus enabling the removal of old diseases and chronic accumulations. However, one must strictly abstain from sexual activity for three months; otherwise, the damaged areas will suffer further severe injury, and the tonification efforts will be severely compromised. Otherwise, one merely achieves temporary relief. One must be cautious! It is advisable to reduce desires.
Marginal Note: Those wishing to conceive should wait until after the cessation of menstruation (luohong), specifically after thirty shichen (two and a half days). Only after the menstrual period has lasted its full thirty shichen can intercourse resume. On the first day, a male child is conceived; on the second, a female; third, male; fourth, female; fifth, male; sixth, female. After the seventh day, conception is no longer possible.
Verse:
When intercourse causes uterine blood flow, fear the worry of blood exhaustion and essence closure.
Treatment must unblock the Qi of the uterus and womb; tonifying essence and Qi cures the disease.
