The best time for pregnant women to take Colla Corii Asini is during mid-pregnancy, half an hour to one hour after meals. Colla Corii Asini is non-toxic, warm in nature and has the effect of nourishing blood, calming the fetus and nourishing Yin. After pregnancy, pregnant women need more nutrients and are often anemic, especially after mid-pregnancy when the fetus grows faster and needs more nutrients, so most pregnant women start to take Colla Corii Asini to nourish their blood after mid-pregnancy. If through routine blood tests, it is found that hemoglobin, etc. is reduced, indicating anemia, it can be taken at any time. However, it is important to control the dosage when consuming it. It is generally recommended to maintain the dosage at about 15g a day, as too much consumption of Colla Corii Asini can easily cause fire or diarrhea. Although the effects of Colla Corii Asini are many, it is not recommended to take it in early and late pregnancy because it has the effect of activating blood and can cause contractions, which can lead to miscarriage in serious cases. Therefore, pregnant women must be cautious when consuming Colla Corii Asini, and it is best to take it under the advice of a doctor.
