It's very good for pregnant women. You can eat black beans if you are pregnant, because Folium Artemisiae Argyi is a Chinese herbal medicine that has the effects of warming meridians, stopping bleeding and preventing miscarriage. For pregnant women with palace cold, Folium Artemisiae Argyi has a good effect of dispelling cold. For pregnant mothers with a history of habitual abortion, drinking boiled eggs with Folium Artemisiae Argyi often during pregnancy can achieve a greater effect of preventing miscarriage. However, boiled eggs with mugwort leaves can not protect all pregnant women from miscarriage. If you are a person with a warm constitution, it is best not to eat boiled eggs with mugwort leaves during pregnancy, because mugwort leaves are warm herbs, and it is easy to get angry if you eat too much.
