First of all, we have to see which kind of traditional Chinese medicine is suitable, what exactly are the ingredients of traditional Chinese medicine, and whether there are any medicines that may not be used during pregnancy, if not, this kind of traditional Chinese medicine is not very influential. The most common Chinese medicines that are drunk for fear of having an effect on pregnancy are those that invigorate blood circulation and remove blood stasis. The medicines that invigorate blood circulation and remove blood stasis are actually not so bad as to cause malformations of the embryo, but mainly because of the invigoration of blood circulation and removal of blood stasis, signs of pre-miscarriage may occur. If the patient is taking drugs that activate Blood and remove Blood stasis, and if she does not experience bleeding or abdominal pain during her early pregnancy, which are signs of preeclampsia, it is generally considered to be fine, as long as she undergoes regular obstetric checkups. Drugs with clear teratogenic effects should never be used during pregnancy, for example, like the Western drug virazole, which has clear teratogenicity and embryonic reproductive toxicity, so it should never be used during pregnancy. As for the study of reproductive toxicity of traditional Chinese medicine, there is no such discovery of drugs that are clearly teratogenic or clearly embryotoxic. Regulate menstruation drugs are generally regulating the qi and blood of Chinese medicine, the impact on the fetus is not great, the impact of traditional Chinese medicine on the fetus, the main consideration is that the toxicity of the drug will have a greater impact.
