Drinking a small amount of patchouli before pregnancy is found to have little effect, but its application is not recommended in early pregnancy. Huo Xiang Zheng Qi Shui contains alcohol and herbal ingredients, and long-term intake of alcohol by pregnant women has the risk of causing fetal malformation. In addition, the herbal ingredients in Huo Xiang Zheng Qi Shui may lead to fetal miscarriage and premature birth, so it is recommended not to use it during pregnancy especially in the first trimester, as this is the critical period that can easily lead to fetal malformation. Of course, if you find a small amount of patchouli before pregnancy, pregnant mothers do not need to be overly nervous and worried, it is recommended to moderate indoor ventilation, drink more water, ensure sufficient rest, and avoid the application of patchouli again. If you feel unwell, go to a regular hospital in time for examination and medication, as well as pay attention to regular maternity checks during pregnancy.
