With the progress of society, the knowledge of eugenics is deeply rooted in people’s hearts, and there are often pregnant female patients referred from other departments in outpatient clinics asking for TCM treatment. They are mainly worried about the impact of careless medication on pregnancy, while Western medicine is limited in its choice of medication and has more toxic side effects, and many drugs are labeled “use with caution during pregnancy”, so there is no way to start. Pregnant women must be careful with their medication because some drugs can damage the fetus or cause miscarriage, especially those with a history of habitual abortion. Of course, you can’t say that pregnant women can’t be treated if they have a disease, especially some common diseases, see a Chinese doctor, with the advantages of Chinese medicine, Chinese medicine has fewer side effects, safe, many Chinese medicine and the role of fetal preservation and fetal. Chinese herbal antifetuses can be divided into those that clear heat and calm the fetus such as Scutellaria baicalensis, those that regulate qi and calm the fetus such as Ziziphi and Sharen, those that strengthen the spleen and calm the fetus such as Atractylodes macrocephala, those that supplement the liver and kidneys and calm the fetus such as Eucommia globulus, Sequoia, and Sang Sang. For those pregnant women with habitual miscarriage, they can be combined with corresponding drugs to achieve the effect of stabilizing and nourishing the fetus. The ancient physicians have long been aware of the contraindications to the use of drugs in pregnancy, and the degree of harm to pregnancy varies from drug to drug. Therefore, they should be treated differently in clinical practice. In modern times, contraindications to pregnancy are divided into two categories: prohibited and cautious, which are mostly highly toxic drugs, or drugs with harsh effects, and drugs with strong abortifacient effects, and cautious drugs are mainly drugs to activate blood circulation and remove blood stasis, qi, attacking drugs, and some of the drugs in the warmth. In the many contraindications to pregnancy gradually deepen the understanding of the reasons for contraindications to pregnancy, mainly from the perspective of eugenics, considering the impact on the mother, fetus, labor, and pediatric. For pregnancy contraindications, without special needs, should try to avoid the use to avoid medical accidents and disputes. If pregnant women have to use them, they should pay attention to accurate identification, master the dosage and treatment course, and minimize the harm of drugs to pregnancy through proper preparation and compounding, so as to achieve effective and safe use of drugs. Since most Chinese medicines are relatively calm and safe for clinical use, they can be used in a synergistic manner through reasonable preparation and combination, and can be used to treat various diseases that occur during pregnancy.
