What kind of gynecological treatment did Chen Ziming propose in Song Dynasty?

Because obstetrics and gynecology was an independent discipline in Song Dynasty, it developed rapidly and there were many monographs, such as Yang Zijian's Ten Productions. Chen's "Women's Prescription" is more representative and is regarded as a classic by the gynecological field of traditional Chinese medicine. There are 24 volumes and 8 chapters in The Good Prescription for Women. The first 3 chapters are the general introduction of gynecology, which discusses menstrual diseases, common miscellaneous diseases and infertility. The last five departments are obstetrics, focusing on the formation and development of fetus, pregnancy examination, delivery, postpartum care, treatment of prenatal and postpartum diseases, and contraindications to medication. Chen believes that menstruation must be adjusted first to treat gynecological diseases, and irregular menstruation will produce many diseases. He put forward the treatment principle of menstrual disease in detail, and realized that the week after menstruation is a woman's pregnancy (equivalent to before and after ovulation). As for whether she is pregnant or not, he suggested that in addition to pulse-cutting, there is also a drug abortion method, that is, grinding raw Chuanxiong into fine powder, roughly frying it, and taking two yuan with wormwood leaf soup as a guide on an empty stomach. If she feels a slight movement in her abdomen, she will be pregnant. Many treatments of gynecological diseases in the book are still very valuable today, such as Ganmai Jujube Decoction for treating women's dirty rashness, Buzhong Yiqi Decoction for treating uterine prolapse and so on. The method of treating amenorrhea caused by female tuberculosis with tonic advocated by him has a great influence on later generations.
