The head nurse Liu Jiaqi's answer:

Many people think that brown sugar has the function of promoting blood circulation, which can promote postpartum congestion, lochia and uterine involution. In fact, it is not recommended to drink brown sugar water for a long time after delivery, and it is generally enough to drink it for 7 ~10 days. Drinking too much is not good for uterine recovery. Because the lochia gradually decreased on postpartum 10 day, the uterine contraction gradually returned to normal. If you drink too much brown sugar water, the blood circulation of brown sugar will increase the blood volume of lochia and prolong the recovery time of uterus.
