It is stated that when the fetal qi (vital energy) moves internally and cannot remain stable, abortion occurs out of season. After the abortion, if the placenta (bao yi) fails to be expelled, it is because the placenta remains attached to the maternal qi and blood. The blood and qi are still consolidated; during the process of abortion, exposure to wind and cold pathogens causes the blood and qi to coagulate and become stagnant, thereby preventing the expulsion of the placenta. The treatment principle should involve using decoctions that break blood stasis and warm the qi.
