 【Predecessors release medicine】
 "Compendium of Materia Medica": "The roots, stems, flowers, leaves and fruits of Leonurus japonicus are all used as medicine and can be used together. If it is used to treat wind-heat in the blood of the hands and feet, improve eyesight and improve essence, and regulate women's meridians, it is better to use Cnidium monnieri alone. If it is used to treat swelling, poison, sores, ulcers, water elimination and blood circulation, and women's pregnancy and childbirth diseases, it is appropriate to use them together. This is because its roots, stems, flowers and leaves are specialized in promoting circulation, while its seeds are tonifying while promoting circulation."
 "Compendium of Materia Medica" states: "Motherwort promotes blood circulation and nourishes blood. It promotes blood circulation without hurting new blood, nourishes blood without stagnating blood, and is truly a holy medicine for blood . When a woman is about to give birth, her qi is not smooth, and the blood is forced to flow indiscriminately, or it is reversed upward, or it is uterine bleeding, or it is not smooth, or the fetus dies in the abdomen, or the placenta does not fall, or lochia attacks the heart, blood swelling and blood dizziness, or it is difficult to produce blood, or it is difficult to go down, or it is vomiting, nausea, restlessness and dizziness. These are all critical symptoms of childbirth, and only motherwort can cure them. In addition, the sore and swelling department uses it to eliminate various toxins, resolve carbuncle, carbuncle, and ulcer, because it can promote blood circulation and detoxify. Eyes It is used by doctors to treat blood in the pupil , headache, and eye pain, because it can promote blood circulation and remove wind. It is believed that motherwort is beneficial to women and focuses on the blood, so it is often used. However , it is good at moving , can promote blood circulation and dredge the menstruation, and can quickly remove blood stasis and stagnation. From its treatment of swelling, carbuncle, and blood obstruction in the eyes, it is known that it can promote blood circulation. It is suitable for postpartum diseases caused by blood stagnation and disharmony of qi and blood vessels. If the name of motherwort is used to treat prenatal symptoms, such as blood deficiency, timidity, insufficient yin, liver deficiency, insufficient blood, dilated pupils, blood loss and metrorrhagia, and yang exhaustion and yin loss, it will always bring harm to the patient. "
 "Compendium of Materia Medica" states: "Motherwort is slippery and astringent in nature, and is good at regulating various symptoms of pregnancy and childbirth in women, hence the name of Motherwort. However, it cannot be said that it is a must-have for women because of its name. It is fine to use its slippery and astringent nature, but it is not good for its tonic effect. "Compendium of Materia Medica" says that long-term use of it can improve sperm quality and lighten the body, but this is not credible. In addition, it can reduce edema, relieve water retention, eliminate blood stasis, and promote urination and defecation, all because of its astringent effect."
 "Ben Jing Feng Yuan" states: "The recipe for the pill is to dry the young leaves of Leonurus in the shade, mix them with urine of a child and aged wine, steam them nine times and dry them nine times, and add them to Siwu Decoction to make pills. It is used to treat various symptoms after childbirth. However, it is only effective in promoting blood circulation, so it is not suitable for those with metrorrhagia, uterine bleeding, weak spleen and stomach, and weak large intestine, because it is of downward nature . In recent times, it is used to treat abdominal pain and vomiting caused by sha, and it is effective to boil it in a concentrated way, add a little raw honey, and drink it warm, because it can disperse bad blood."
 "Compendium of Materia Medica" states: "Motherwort can eliminate water and promote blood circulation, remove blood stasis and promote new blood, regulate menstruation and detoxify, and is an essential medicine before and after pregnancy. Therefore, if there is hematuria, blood retention, metrorrhagia, leucorrhea and blood pain in the absence of pregnancy, fetal leakage in the pregnancy, labor difficulties in labor, blood fainting after delivery, carbuncle, breast swelling and other symptoms, taking this herb can remove blood stasis and promote new blood circulation. The pungent taste can disperse wind and activate blood, the bitter taste can eliminate blood stasis and remove knots, and the cold qi can treat heat, and it can be used according to the symptoms, which is beneficial to the mother."
 "Compendium of Materia Medica" states: "Although Yimu is not a very warm and hot medicine, it has a strong smell and bitter taste . It is a warm and dry medicine. If you take it for two or three days after giving birth, you will have dry mouth and throat. This is especially true. Therefore, it is suitable for cold people with cold body, but not for hot people with hot body. It is regarded as a must-have for postpartum women in my hometown. Even in the hot summer, it must be kept on hand. In addition, it is afraid of its bitterness and dryness, so it is always mixed with sugar. If you take this turbid, bitter and dry medicine during the dog days of summer and have a weak body after giving birth, it will consume blood and attract evil spirits, which may cause unexpected changes, which is even more worrying."
