If a pregnant woman is emaciated and weak, or complicated by disease, leading to deficiency and damage of the Zang-Fu organs and exhaustion of Qi and Blood, since she cannot nourish the fetus, causing fetal movement instability and insecurity, ultimately failing to secure the pregnancy, abortion (induced expulsion of the fetus) may be performed to prevent harm to the mother. If a pregnant woman is infected with pathogenic factors from warm epidemics or Cold Damage (Shanghan), which enter the uterus and Zang-Fu organs, causing fetal death, if the area where fetal movement was previously felt feels cold, indicating fetal death, abortion may be performed.
